Simplified Marginal Effects in Discrete Choice Models
Provedor de dados: 31
Autores: Anderson,   Soren T.; Newell,   Richard G.
We show that after a simple normalization of explanatory variables so that they equal zero at some desired reference point, marginal effects for continuous variables in probit and logit models simplify dramatically, becoming a function of only the estimated constant term. We present similar simplifications for computation of the asymptotic variance of marginal effects, as well as for the effects of dummy variables on predicted probabilities. We provide a simple table, which in combination with raw probit or logit estimates, is all one needs to compute the desired effects.

Factors Influencing Job Choice among Agricultural Economics Professionals
Provedor de dados: 31
Autores: McGraw,   Katherine; Popp,   Jennie S. Hughes; Dixon,   Bruce L.; Newton,   Doris J.
This article identifies factors that influence agricultural economics professionals’ job choice between academic and government employment. Respondents agreed that job responsibilities were the most important factor in choosing their current position. They also agreed that having a positive work environment, good salary, family time, adequate resources, and professional and social interaction were important job attributes. Proportionally more women than men regarded partner opportunities, nondiscrimination, time for child care, and supportive colleagues as very important attributes influencing their decisions. A binomial probit of respondents’ current job sector indicates significant job choice determinants include sector preference (academic or...

THE INFLUENCE OF ATTRIBUTE CUTOFFS ON CONSUMERS’ CHOICES OF A FUNCTIONAL FOOD
Provedor de dados: 31
Autores: Ding,   Yulian; Veeman,   Michele M.; Adamowicz,   Wiktor L.
This study investigates evidence of non-compensatory preferences by incorporating attribute cutoffs into the modeling of consumer choices in the context of food with health-related attributes (omega-3 content) that may be associated with fortification or may result from genetic modification (GM). Data for this study were collected through a nation-wide internet-based survey drawn from a representative panel of Canadian households maintained by a major North American marketing firm. In addition to querying respondents on their perceptions and attitudes regarding food and health, choices of canola oils are elicited using a stated choice experiment in which product alternatives are identified based on attributes of price, country of origin, omega-3 content...

Consumer Acceptance of GM Applications in the Pork Production Chain: A Choice Modelling Approach
Provedor de dados: 31
Autores: Novoselova,   Tatiana A.; van der Lans,   Ivo A.C.M.; Meuwissen,   Miranda P.M.; Huirne,   Ruud B.M.
This study evaluates consumer acceptance of different GM applications in the pork production chain. In general, results indicate that consumers prefer conventional pork over pork for which genetic modification was applied. However, the negative impact of the GM applications is compensated by improvements in quality, increased animal welfare, a lower impact on the environment, less residues and a price discount. Of these benefits, increased animal welfare has the most positive effect on consumer choices. With substantial monetary compensation and presence of various benefits the consumers will attach higher utility to the GM pork than to the conventional pork. The amount of monetary compensation is dependent on the type of GM application.

Factors Affecting Perceived Improvements in Environmental Quality from Precision Farming
Provedor de dados: 31
Autores: Larkin,   Sherry L.; Perruso,   Larry; Marra,   Michele C.; Roberts,   Roland K.; English,   Burton C.; Larson,   James A.; Cochran,   Rebecca L.; Martin,   Steven W.
This study identified the factors that influenced whether farmers in the Southeastern United States perceived an improvement in environmental quality from adopting precision farming technologies (PFTs). Farmers with larger farms or higher yields were more likely to believe that they observed positive externalities associated with PFTs. Farmers who found PFTs profitable or who believed input reduction was important had higher probabilities whereas those with higher incomes or who were more dependent on farm income were less likely to perceive such benefits. Interestingly, the importance of environmental quality and length of time using PFTs were not found to affect the probability of perceiving an improvement in environmental quality.

Do Interest Groups Compete?
Provedor de dados: 31
Autores: Ando,   Amy Whritenour.
This paper conducts a test of the hypothesis that interest groups compete strategically for influence with a policy-making agency. It adapts econometric methodology from the empirical industrial organization literature that was designed to work with discrete game-theoretic models, and uses data on whether or not supporting and opposing interest groups submitted comments to the Fish and Wildlife Service about each of 173 proposals to add new species to the endangered species list. The results imply that groups do respond to variations in the expected costs and benefits of a listing when deciding whether to pressure the agency. There is no support, however, for the hypothesis that the levels of pressure exerted by the groups emerge from the Nash equilibrium...

Land Use Change: A Spatial Multinomial Choice Analysis
Provedor de dados: 31
Autores: Carrion-Flores,   Carmen E.; Flores-Lagunes,   Alfonso; Guci,   Ledia.
Urban decentralization and dispersion trends have led to increased conversion of rural lands in many urban peripheries and exurban regions of the U.S. The growth of the exurban areas has outpaced growth in urban and suburban areas, resulting in growth pressures at the urban-rural fringe. A thorough analysis of land use change patterns and the ability to predict these changes are necessary for the effective design of regional environmental, growth, and development policies. We estimate a multinomial discrete choice model with spatial dependence using parcel-level data from Medina County, Ohio. Accounting for spatial dependence should result in improved statistical inference about land use changes. Our spatial model extends the binary choice “linearized...

Effects of Socio-Institutional and Emotional Factors of Japanese Farmland Rental Transactions
Provedor de dados: 31
Autores: Kunimitsu,   Yoji.
Farmland reallocation between farmers through rental transactions is critical for improving Japanese rice productivity.  This study examined effects of socio-institutional and emotional factors as well as economic factors on rental transactions.  A stochastic choice model was applied to contingent valuation data by considering regional heteroscedasticity.  Empirical results showed (1) existence of economic inefficiencies, 3% loss of economic surplus due to socio-institutional restriction, which is probably reflected in transaction costs; (2) a 15% reduction in surplus due to emotional reluctance of farmers; and (3) strong influences of rice price, wages, and geographical location on the rental rate and agreement level.

Can Co-Management Improve the Governance of   A Common- Pool Resource? Lessons From A Framed Field Experiment in A Marine Protected Area in the Colombian Caribbean
Provedor de dados: 31
Autores: Moreno-Sanchez,   Rocio del Pilar; Maldonado,   Jorge Higinio.
Complexities associated with the management of common pool resources (CPR) threaten governance at some marine protected areas (MPA). In this paper, using economic experimental games (EEG), we investigate the effects of both external regulation and the complementarities between internal regulation and non-coercive authority intervention—what we call co-management—on fishermen’s extraction decisions. We perform EEG with fishermen inhabiting the influence zone of an MPA in the Colombian Caribbean. The results show that co- management exhibits the best results, both in terms of resource sustainability and reduction in extraction, highlighting the importance of strategies that recognize communities as key actors in the decision-making process for the...

An Analysis of Demand Elasticities for Fluid Milk Products in the U.S.
Provedor de dados: 31
Autores: Davis,   Christopher G.; Blayney,   Donald P.; Cooper,   Joseph C.; Yen,   Steven T.
This study examines retail fluid milk products purchase data from Nielsen 2005 home scan data. The demand for seven categories of fluid milk products were estimated: whole milk, whole flavored milk, reduced fat milk, flavored reduced fat milk, buttermilk, canned milk and all other fluid milk products.  Analyses of the purchases of seven fluid milk categories based on the Nielsen 2005 home scan retail data are used to determine the roles marital status, age, race, education, female employment status and location play in the empirical estimations of aggregate demand elasticities.  To derive the demand elasticities, a censored translog demand system is used.  The results reveal that price and income are the main determinants of demand for fluid milk products...

Diversification of the marketing chains among organic producers
Provedor de dados: 31
Autores: Corsi,   Alessandro; Borsotto,   Patrizia; Borri,   Ilaria; Strom,   Steinar.
Diversification of consumers’ demand and environmental concerns are at the origin of a trend towards short marketing chains and towards direct links between consumers and farmers in developed countries. This paper explores farmers’ motivations for choosing these types of marketing chains and/or the “traditional” ones. To this purpose, a theoretical model of marketing chain choice is developed, and a multivariate probit model of organic farmers’ choice of the marketing chain is estimated from a unique data set of organic farms in an Italian region.

Residential Land Values in Urbanizing Areas
Provedor de dados: 31
Autores: Kaltsas,   Ioannis K.; Bosch,   Darrell J.; McGuirk,   Anya M.
Zoning decisions related to residential lot size and density affect residential land value. Effects of size on residential parcel value in Roanoke County, VA, are estimated with fixed effects hedonic models. Parcel size; elevation; soil permeability; proximity to urban areas, malls, and roads; and location influence parcel value, but the effects vary by value of construction and development status. Parcel value per square meter declines with increasing parcel size. The estimated relationships could be used to evaluate zoning decisions in terms of land values and tax revenues if model estimation uncertainties and responses by developers to zoning strategies are considered.

Testing for a Supply Constraint to Fertility: Interpreting the Up to God Response to the Survey Question on Desired Family Size
Provedor de dados: 31
Autores: Sinha,   Nistha.
The paper outlines a methodology that allows us to determine whether couples’ fertility is supply constrained based on the response they give to the subjective desired family size question. The central idea of the paper is that, when faced with the desired family size question, both constrained and unconstrained couples compare their demand for children with knowledge of their biological supply and unconstrained couples respond with a number while constrained couples respond with a qualitative response such as, “It is Up to God” (UTG), that essentially conveys the notion of demanding as many children as the supply function can yield. I then test this interpretation using data from Bangladesh. I find that controlling for demand side characteristics,...

The study focuses on various types of food safety risks: biological (zoonoses), chemical (chemical treatment of the meat) and technological (use of genetically modified feed). The emphasis was on how the perceived risks affect the purchase intentions in the case of broiler meat. In the case of each risk products the attitude-level variables had importance in explaining the buying intentions. The heterogeneity of the respondents regarding the purchase intentions of risk products was analysed by latent class logistic regression that included all three risk products. About 60% of the respondents belonged to the group of risk avoiders in which the purchase intention of risk food was significantly lower than in the second group of risk neutrals in which 64% of...

Autores: Lapar,   Ma. Lucila A.; Toan,   Nguyen Ngoc; Que,   Nguyen Ngoc; Jabbar,   Mohammad A.; Tisdell,   Clement A.; Staal,   Steven J.
This paper reports on the findings of a study to investigate market outlet choice decision-making of urban consumers in Vietnam with regards to fresh pork purchases and generate empirical evidence on factors that influence these choices.  Data from a survey of 600 consumers in Hanoi and Ho Chi Minh City was used to estimate a multinomial logit model of market outlet choice based on three alternatives: traditional temporary market outlets, permanent open markets, and modern retail outlets.  Results suggest that market outlet choice by consumers of fresh pork in urban cities of Vietnam is conditioned by factors related to mobility and level of affluence, time budgets, concerns about food safety and hygiene, proximity to market outlets, and geographical...

Do Environmental Services Buyers Prefer Differentiated Rates? A Case Study from the Colombian Andes
Provedor de dados: 31
Autores: Moreno-Sanchez,   Rocio del Pilar; Maldonado,   Jorge Higinio; Wunder,   Sven; Borda,   Carlos Andres.
Flat user fees in payment for environmental services (PES) schemes promote administrative ease, and are sometimes perceived as egalitarian. However, when environmental service (ES) buyers are heterogeneous in their income and water consumption levels, this may not be optimal, as total payments become too low and services are under-supplied. This paper identifies ES buyer preferences and estimates their willingness to pay (WTP) differentiated fees in an ongoing PES initiative in an Andean watershed in Colombia. Small, flat user payments have recently been introduced to implement incipient watershed protection upstream. Environmental service users fall into two highly heterogeneous categories: smallholder peasants and owners of recreational houses. We...

Use of Spike Models in Measuring Consumers' Willingness to Pay for Non-GM Oil
Provedor de dados: 31
Autores: Hu,   Wuyang.
In this paper, Chinese consumers' preferences and their willingness to pay (WTP) for non-genetically modified (GM) vegetable oil were elicited by a payment card approach. In addition to the conventional model, spike models, which were originally developed to evaluate public goods, were adopted in this paper. These spike models recognize the possibility of zero WTP and provide opportunities to analyze two correlated decision stages: whether to pay a premium for non-GM oil and how much the premium is. Results show that consumers behaved consistently in the two decision stages and there is a premium associated with non-GM oil.

Autores: Araujo,   Claudio; Araujo-Bonjean,   Catherine; Brunelin,   Stephanie.
The aim of this paper is to exploit grain price data to detect the warning signs of looming food crises in Mali, Burkina Faso and Niger. Firstly we identify which markets play a leading role at the national and regional level. The second step consists of identifying crisis periods and characterizing price movements during the period proceeding a crisis. This analysis leads to the identification of early warning indicators whose relevance is tested using panel data qualitative choice models. The results show that monitoring price movements on "leading markets" during crucial periods of the year can help in forecasting future crises.

Discrete choice models, which one performs better?
Provedor de dados: 31
Autores: Gallardo,   Rosa Karina; Chang,   Jae Bong.
For over the last thirty years the multinomial logit model has been the standard in choice modeling.  Development in econometrics and computational algorithms has led to the increasing tendency to opt for more flexible models able to depict more realistically choice behavior.  This study compares three discrete choice models, the standard multinomial logit, the error components logit, and the random parameters logit.  Data were obtained from two choice experiments conducted to investigate consumers’ preferences for fresh pears receiving several postharvest treatments. Model comparisons consisted of in-sample and holdout sample evaluations.  Results show that product characteristics hence, datasets, influence model performance. We also found that the...

Using a series of hurdle choice models, this study considers both nay-saying and yeah-saying to alternatives offered in a conjoint experiment.  These behaviors are characterized by respondents persistently choosing the no-choice alternative or choosing at least one of the non-empty options offered in a survey.  Results show that jointly consider nay-saying and yeah-saying in a two-hurdle model drastically improves model fit; welfare implications based on hurdle models are also different from those based on models without hurdle specification.

Standard and Shuffled Halton Sequences in a Mixed Logit Model
Provedor de dados: 31
Autores: Staus,   Alexander.
Modeling consumer choice in different areas has lead to an increase use of discrete choice models. Probit or Multinomial Logit Models are often the base of further empirical research of consumer choice. In some of these models the equations to solve have no closed-form expression. They include multi-dimensional integrals which can not be solved analytically. Simulation methods have been developed to approximate a solution for these integrals. This paper describes the Standard Halton sequence and a modification of it, the Shuffled Halton sequence. Both are simulation methods which can reduce computational effort compared to a random sequence. We compare the simulation methods in their coverage of the multi-dimensional area and in their estimation results...

Precaution and Protectionism: GM Food and the WTO
Provedor de dados: 31
Autores: Rigby,   Dan; Burton,   Michael P.; Young,   Trevor.
The dispute between the US and EU over GM foods at the WTO is examined in terms of the issues it raises about protectionism and environmental protection and precaution. The issue of whether GM, GM Derived and Non-GM foods are equivalent to each other is examined using data from a national choice modelling study in the UK. These categories of food are critical since they underpin the EU's new food labelling regime which it hoped would defuse the WTO dispute. The results are analysed using a Bayesian mixed logit model which allows greater flexibility in the modelling of preference distributions. This is particularly crucial where, as in this case, bi-modal distributions are identified with some indifferent or mildly averse to GM foodtypes while others are...

Estimating Tourist Externalities on Residents: A Choice Modeling Approach to the Case of Rimini
Provedor de dados: 31
Autores: Figini,   Paolo; Castellani,   Massimiliano; Vici,   Laura.
During their holidays, tourists produce direct and indirect effects on local residents, which can either be positive or negative. In this paper we investigate how residents of Rimini, a popular Italian seaside resort hosting more than ten million national and foreign overnight stays every year, internalise such effects. We use a stated preference approach and, in particular, a discrete choice modelling technique; within this framework, we are able to test some conjectures about residents’ welfare, by measuring their willingness to pay for alternative scenarios regarding the use of the territory. Tourist policies and public investments in the destination affect residents’ welfare, and our results might suggest areas of potential synergies and trade-off,...

Economics of Groundwater Irrigation in Nepal:  Some Farm-Level Evidences
Provedor de dados: 31
Autores: Bhandari,   Humnath; Pandey,   Sushil.
This article examines the economics of groundwater irrigation and shallow tubewell (STW) ownership decision making, using farm-level data collected from 324 households in Nepal.  STW irrigation generated a significant positive effect on rice yield and farmers’ incomes.  Based on a probit model, the farm size, land fragmentation, access to electricity, and access to credit were found to significantly influence farmers’ decisions to own STWs.  Although the water market benefited poor farmers, it is too small and monopolistic.  Policy reforms needed to make groundwater accessible to the poor majority include effective credit programs, investments in rural electrification, and public sector support for promoting suitable pumping technologies

We study the effects of a conditional transfers program on school enrollment and performance in Mexico. We provide a theoretical framework for analyzing the dynamic educational decision and process including the endogeneity and uncertainty of performance (passing grades) and the effect of a conditional cash transfer program for children enrolled at school. Careful identification of the program impact on this model is studied. This framework is used to study the Mexican social program Progresa in which a randomized experiment has been implemented and allows us to identify the effect of the conditional cash transfer program on enrollment and performance at school. Using the rules of the conditional program, we can explain the different incentive effects...

Autores: Barreiro-Hurlé,   Jesús; Espinosa-Goded,   Maria; Dupraz,   Pierre.
El carácter voluntario de los programas agroambientales hace que su éxito dependa del grado de aceptación por parte de los agricultores. La decisión de participación es compleja, ya que está condicionada por una gran variedad de factores. Este estudio amplía el análisis de la elección de la mejor alternativa de gestión para una explotación agraria en presencia de programas agroambientales analizando de manera explícita el papel que juega el capital social. Los resultados señalan la importancia de este concepto, tanto en medidas con escasos requisitos de cambio como en medidas más exigentes para los agricultores.

Food purchasing in Brazil has undergone major changes in the last few decades caused by structural shifts such as urbanization, changes in demographic characteristics and increase in participation of women in the labor force. Therefore, it is necessary to identify thoroughly new consumption patterns of families, especially concerning determinants of food purchasing decision. The objective of this study was to understand the consumption pattern of Brazilian families for food products by means of a qualitative response variable model including eighteen food products using POF 2002/2003 data. The Probit model was chosen to estimate this decision. Estimation results showed that purchasing probabilities of staple foods were negative related to family monthly...

Determinants of the Extension of Part-time Farming--Results from a Probit Approach
Provedor de dados: 31
Autores: Harsche,   Johannes.
This paper presents a Probit model explaining the employment decisions of farmers located in the German State of Hesse. The model is based on a cross-section analysis including data from 74 Hessian farmers. It indicates empirically a strong impact from wages on employment decisions of farmers. It also verifies the importance of the personal type of entrepreneur for their working behaviour. Finally, we can conclude that, regarding working behaviour, farmers react to signals from the labour market conditions as well as to the structural transformation process in the agricultural sector.

Integrating Routine, Variety Seeking and Compensatory Choice in a Utility Maximizing Framework
Provedor de dados: 31
Autores: Adamowicz,   Wiktor L.; Swait,   Joffre.
Given the large number of choices that consumers make each day it seems likely that they will generally adopt decision strategies that minimize cognitive effort, particularly with low price products such as most items found in a supermarket. One such strategy may be to simply choose what has been chosen in the past, i.e. to fall into a pattern of routine choices or decisions. In contrast, there may be preferences for variety in markets for low price, highly differentiated goods. We develop a conceptual and empirical model of routine choice, and the factors that result in transitions to two strategies other than routine selection, to wit, utility maximizing choice among available alternatives and a variety seeking strategy. The empirical approach we employ...

Modern Supply Chains and Product Innovation: How Can Smallholder Farmers Benefit?
Provedor de dados: 31
Autores: Schipmann,   Christin; Qaim,   Matin.
There is an emerging body of literature analysing how smallholder farmers in developing countries can benefit from modern supply chains. However, most of the available studies concentrate on export markets and fail to capture spillover effects that modern supply chains may have on local markets. Here, we analyse the case of sweet pepper in Thailand, which was initially introduced as a product innovation in modern supply chains, but which is now widely traded also in more traditional markets. Using survey data from smallholder farmers and econometric techniques, we show that sweet pepper cultivation contributes significantly to higher household incomes. Strikingly, at this stage, participation in modern supply chains does not lead to higher incomes than...

Does Price or Income Affect Organic Choice? Analysis of U.S. Fresh Produce Users
Provedor de dados: 31
Autores: Smith,   Travis A.; Huang,   Chung L.; Lin,   Biing-Hwan.
This study analyzes consumer purchasing behavior of organic fresh fruits and vegetables using the 2006 Nielsen Homescan panel. An ordered logit model was estimated to quantify the impacts of economic and socio-demographic factors on the probability of a household belonging to a specific organic user group—devoted, casual, or nonuser. Results suggest that price and income, to some extent, affect consumer purchases of organic produce. Additionally, the profile of an organic produce user is most likely to consist of an Hispanic household residing in the Western United States with children under 6 years old and a household head older than 54 years with at least a college degree.

Measuring Retail Service Quality in Farm Supply Cooperatives
Provedor de dados: 31
Autores: Wilson,   Norbert L.W.; Hall,   Thomas; Fields,   Deacue.
Based on the Retail Service Quality Scale (RSQS), we develop a tool for mangers of local farm cooperative stores to assess which customer service groups matter to their customers. Principal component analysis (PCA) reveals three customer groups. The results of the multinomial logit model showed younger patrons and homeowners are likely to deem customer service and personal interaction as important. Customers, who consider appearance and accessibility as important, are college graduates and persons dependent on farming. Older patrons and wildlife enthusiasts are likely to view the policies and reliability as important factors of service quality.

Testing Nonlinear Logit Models of Performance Effectiveness Ratings: Cooperative Extension and Organic Farmers
Provedor de dados: 31
Autores: Lohr,   Luanne; Park,   Timothy A.
Survey evidence from U.S. organic farmers is evaluated to identify the factors influencing effectiveness ratings of cooperative extension advisors by organic farmers. A nonlinear logit model is specified for the ratings provided by organic producers, and critical demographic and management factors that influence the ratings are identified. The impact of the organic farmers’ status in transitioning to organic production is highlighted. The results indicate that part-time, newer adopters of organic farming methods are more likely to rate extension service providers as effective providers of information. Scenarios to predict extension effectiveness when interacting with specific groups of organic farmers are developed.

Like Oil and Water or Chocolate and Peanut Butter? Ethnic Diversity and Social Participation of Young People in England
Provedor de dados: 31
Autores: Fumagalli,   Elena; Fumagalli,   Laura.
The paper studies the impact of ethnic diversity on social participation of young people. We first propose a theoretical model in which the agents choose between structured and unstructured social activities by taking into account the ethnic composition of the groups they join. We test our predictions using English census data together with the `Longitudinal Survey of Young People in England' (LSYPE) and we find that ethnic segregation increases the probability of hanging around near home, while ethnic fractionalization decreases it. Furthermore, more structured activities are not affected by ethnic fractionalization. Finally, we use an IV strategy based on both historical and geographical data to correct for endogenous sorting into neighborhoods. The...

U.S. cheese consumption has grown considerably over the last three decades. Using a censored demand model and Nielsen Homescan retail data, this study identifies price and non-price factors affecting the demand for differentiated cheese products. Own-price and expenditure elasticities for all of the cheese products are statistically significant and elastic. Results also reveal that a strong substitution relationship exists among all cheese products. Although demographic influences are generally smaller than those related to prices and expenditures, empirical findings show that household size, college educated female heads of household who are age 40 and older, residing in the South, Central, and Western regions of the United States, as well as Black heads...

A TWO-STEP ESTIMATOR FOR A SPATIAL LAG MODEL OF COUNTS: THEORY, SMALL SAMPLE PERFORMANCE AND AN APPLICATION
Provedor de dados: 31
Autores: Lambert,   Dayton M.; Brown,   Jason P.; Florax,   Raymond J.G.M.
Several spatial econometric approaches are available to model spatially correlated disturbances in count models, but there are at present no structurally consistent count models incorporating spatial lag autocorrelation. A two-step, limited information maximum likelihood estimator is proposed to fill this gap. The estimator is developed assuming a Poisson distribution, but can be extended to other count distributions. The small sample properties of the estimator are evaluated with Monte Carlo experiments. Simulation results suggest that the spatial lag count estimator achieves gains in terms of bias over the aspatial version as spatial lag autocorrelation and sample size increase. An empirical example deals with the location choice of single-unit start-up...

Estimation and Welfare Calculations in a Generalized Corner Solution Model with an Application to Recreation Demand
Provedor de dados: 31
Autores: Phaneuf,   Daniel J.; Kling,   Catherine L.; Herriges,   Joseph A.
The Kuhn-Tucker model of Wales and Woodland (1983) provides a utility theoretic framework for estimating preferences over commodities for which individuals choose not to consume one or more of the goods. Due to the complexity of the model, however, there have been few applications in the literature and little attention has been paid to the problems of welfare analysis within the Kuhn-Tucker framework. This paper provides an application of the model to the problem of recreation demand. In addition, we develop and apply a methodology for estimating compensating variation, relying on Monte Carlo integration to derive expected welfare changes.

Community Pressure and Clean Technology in the Informal Sector: An Econometric Analysis of the Adoption of Propane by Traditional Mexican Brickmakers
Provedor de dados: 31
Autores: Blackman,   Allen; Bannister,   Geoffrey J.
In many developing countries the informal sector, comprised of low-technology unlicensed micro-enterprises, is a major source of pollution. Environmental management in this sector is exceptionally challenging. Though clean technologies offer a means of mitigating the problem, to our knowledge there has been no rigorous empirical research on why informal (or even small-scale) firms do and do not adopt them. As a first step towards filling this gap, this paper presents the results of an econometric analysis of the diffusion of propane among informal 'traditional' brickmakers in Cd. Juárez, Mexico--a leading source of air pollution owing to their reliance on cheap, highly polluting fuels such as used tires and scrap wood. The two key policy implications of...

Autores: Davis,   Christopher G.; Stefanova,   Stela; Hahn,   William F.; Yen,   Steven T.
In this study we estimated the price elasticities among meats, vegetables, grains, and potatoes and the impact that different levels of income have on the demand for these commodities.  The 2005 Nielsen retail home scan data were used to construct a censored demand system of 14 equations.   Results revealed that the uncompensated cross-price elasticities for both low and high-incomes suggest both substitution and complement relationships, while the compensated price elasticities are dominated primarily by substitution relationships.  Our findings also revealed that expenditure elasticities among both low and high-income households differ for most commodities.

Participation of small businesses in the market for public contracts is widely recognized as a key policy issue. It is also commonly held that the adoption of e-procurement solutions can be effective in pursuing such an objective. To this end, we analyze the transactions completed in the period 2004-2007 through the Italian Government’s e-procurement platform, that is, the marketplace managed by the Italian Public Procurement Agency (Consip S.p.A.). Although descriptive statistics indicate that micro suppliers are the most represented group of firms in the marketplace, our econometric treatment provides some evidence that the former are less successful than all other suppliers in getting public contracts.

Cow-Calf Producer Risk Preference Impacts on Retained Ownership Strategies
Provedor de dados: 31
Autores: Pope,   Kelsey Frasier; Schroeder,   Ted C.; Langemeier,   Michael R.; Herbel,   Kevin L.
Considerable efforts have been made to provide cow-calf producers with information to help them make informed decisions about adding value to calves. Despite demonstrated market incentives to retain calves, many producers still sell right after weaning. We postulate this observed behavior is related to producer risk aversion. Our study concludes risk aversion is an important factor affecting calf retention as the most risk-averse producers have more than a 60% probability of selling calves at weaning and the most risk tolerant have less than a 20% probability of selling at weaning.

Autores: Tiller,   Kelly; Feleke,   Shiferaw T.; Starnes,   Jane H.
This study explores the relationship between family/farm characteristics and the probability of exiting burley tobacco farming in Tennessee, North Carolina, and Virginia. Following the termination of the federal tobacco program in 2004, 54% of burley tobacco–growing households in Tennessee, North Carolina, and Virginia exited burley tobacco farming by 2006. Tobacco yield, tobacco farm cash receipts, tobacco price, off-farm employment, and farm size are the most dominant variables discriminating between exiting and surviving tobacco farms. Data for this study came from a mail survey of burley tobacco producers in Tennessee, Virginia, and North Carolina in May 2006.

MONITORING CHOICE TASK ATTRIBUTE ATTENDANCE IN NON-MARKET VALUATION OF MULTIPLE PARK MANAGEMENT SERVICES: DOES IT MATTER?
Provedor de dados: 31
Autores: Scarpa,   Riccardo; Thiene,   Mara; Hensher,   David A.
Land management in Alpine Parks provides multifunctional services to separate groups of users. Choice experiments can be used to derive estimates of value for different management attributes. However, little research has been conducted on how frequently respondents ignore attributes used to describe policy management scenarios. We fill this gap using an approach that identifies and compares both serial and choice-task attribute non-attendance addressing five different visitor types. Our results indicate that accounting for choice-task non-attendance significantly improves model fit and yield estimates of marginal WTP with a more plausible pattern of signs and greater efficiency.

To reduce the potential for response bias on the follow-up bid in multiple-bound discrete choice CVM questions while maintaining much of the efficiency gains of the multiple-bound approach, we introduce the one-and-one-half-bound (OOHB) approach. Despite the fact that the OOHB model uses less information than the double-bound (DB) approach, efficiency gains in moving from single-bound to OOHB capture a large portion of the gain associated with moving from single-bound to DB. In an analysis of survey data, our OOHB estimates demonstrated higher consistency with respect to the follow-up data than the DB estimates and were more efficient as well.

Demand for Private Marketing Expertise by Organic Farmers: A Quantile Analysis Based on Counts
Provedor de dados: 31
Autores: Lohr,   Luanne; Park,   Timothy A.
We study the demand by organic farmers for technical advice using a quantile regression for the demand of organic farmers for consultations with private information providers. There is substantial heterogeneity in the impact of critical explanatory variables on consultations of organic farmer. Larger farm size has a positive effect on contacts, but the effect is absent for the highest number of consultations. Internet use has a positive marginal effect on visits to private information providers across each quantile, suggesting that expanded efforts to deliver programs through web-based resources are a useful investment for information providers.

Autores: Watson,   Susan; Nwoha,   Ogbonnaya John; Kennedy,   Gary A.; Rea,   Kenneth.
The probability of a business paying various amounts of money for an e-commerce presence ultimately depends on demographic features, experiences with e-commerce from a buyer’s and seller’s perspective, technological expertise, and knowledge of e-commerce opportunities and limitations.  Estimating functions to assign probabilities associated with the willingness to pay for an e-commerce presence will assist in forecasting regional likelihood of certain profiles paying various monetary amounts for an e-commerce presence.  In addition, if services are provided at no cost by a third party, value to a society will be maximized by selecting profiles with the highest willingness to pay.

Modelling heterogeneity in response behaviour towards a sequence of discrete choice questions: a probabilistic decision process model
Provedor de dados: 31
Autores: McNair,   Ben J.; Heshner,   David A.; Bennett,   Jeffrey W.
There is a growing body of evidence in the non-market valuation literature suggesting that responses to a sequence of discrete choice questions tend to violate the assumptions typically made by analysts regarding independence of responses and stability of preferences. Decision processes (or heuristics) such as value learning and strategic misrepresentation have been offered as explanations for these results. While a few studies have tested these heuristics as competing hypotheses, none has investigated the possibility that each explains the response behaviour of a subgroup of the population. In this paper, we make a contribution towards addressing this research gap by presenting a probabilistic decision process model designed to estimate the proportion of...

An increasing number of studies deals with consumer decisions regarding organic food, but only a few provide quantitative estimates of price and income elasticities. This paper contributes to the existing literature by providing own-price elasticity estimates as well as an analysis of the sociodemographic determinants of demand for organic milk. The analysis is based on the GfK Consumer Scan Scanner panel dataset on food purchases of German households covering a sample period of four years from 2004 to 2007. A two-step estimation procedure is applied. First, a probit regression examines which household characteristics affect the probability to buy organic milk. Second, a fixed-effects panel regression determines factors that have an impact on the quantity...

Autores: Kimenju,   Simon Chege; De Groote,   Hugo.
A survey of 600 consumers was conducted in Nairobi to determine attitudes and willingness to pay (WTP) for GM maize meal. WTP was estimated using the double-bounded logit model. Overall, 38% are aware of GM crops. Most consumers believe in the technology's positive impacts, but are concerned about environmental and health risks. Majority (68%) would buy GM maize meal at the price of their favourite maize meal brand. The mean WTP for GM maize meal is KShs 58 for a 2kg packet, a premium of 13.7 % over mean average price of favourite brands. WTP is influenced more by subjective than socioeconomic characteristics.

Promotion and Fast Food Demand: Where's the Beef?
Provedor de dados: 31
Autores: Richards,   Timothy J.; Padilla,   Luis.
Many believe that fast food promotion is a significant cause of the obesity epidemic in North America. Industry members argue that promotion only reallocates brand shares and does not increase overall demand. This study weighs into the debate by specifying and estimating a discrete/continuous model of fast food restaurant choice and food expenditure that explicitly accounts for both spatial and temporal determinants of demand. Estimates are obtained using a unique panel of Canadian fast food consumers. The results show that promotion primarily increases demand and has very little effect on restaurant market shares.

Farming Exit Decision by Age Group: Analysis of Tobacco Buyout Impact in Kentucky
Provedor de dados: 31
Autores: Pushkarskaya,   Helen N.; Vedenov,   Dmitry V.
This article analyzes factors that affected the decision to exit tobacco production in the wake of the tobacco buyout program using the data collected through a survey of Kentucky tobacco farmers. Using the Heuristic logistic regression model, we find that the decision to exit tobacco growing was affected by efficiency considerations, availability of off-farm employment, and exit barriers. Availability of off-farm employment had the strongest effect on farmers younger than 46, while the effect of variables measuring efficiency and exit barriers seemed to be more uniform across age groups. Based on the results we suggest several policy interventions.

Information generated by precision farming technologies is of particular importance to producers. Precision farming technologies implies the ability to improve the management of production factors using site-specific information. This study examines factors influencing cotton farmers’ perceptions about the importance of crop consultants, farm input dealerships, Extension, other farmers, trade shows, the Internet and printed news/media for making precision farming decisions using a rank ordered logit model (ROLM). Results suggest that age, land tenure, income, percentage of income from farming, and location may affect farmers’ perceptions about the importance of different information sources when making decisions about precision farming technologies....

Where one shops, food beliefs and food knowledge have the largest significant impact on the probability that shoppers buy organic food. Among the demographic characteristics, only the lack of religious affiliation, higher education, and youth are significant explanatory variables.

Why Don't Farmers Adopt Precision Farming Technologies in Cotton Production?
Provedor de dados: 31
Autores: Paudel,   Krishna P.; Pandit,   Mahesh; Mishra,   Ashok K.; Segarra,   Eduardo.
We used the 2009 Southern Cotton Precision Farming Survey data collected from farmers in twelve U.S. states (Alabama, Arkansas, Florida, Georgia, Louisiana, Missouri, Mississippi, North Carolina, South Carolina, Tennessee, Texas, and Virginia) to understand why farmers do not adopt seemingly profitable precision farming technology. Farmers provided cost, time constraint, satisfaction with the current practice and other as reasons for not adopting precision farming technology. Results from a multinomial logit regression model indicated that manure application on field, more formal education, larger farm size, participation in conservation easement or agricultural easement generally decreases the probability of nonadoption of precision agriculture in cotton...

An Ordinal Regression Model using Dealer Satisfaction Data
Provedor de dados: 31
Autores: Staus,   Alexander.
This article analyses dealer satisfaction data in the agricultural technology market in Germany. The dealers could rate their suppliers in the ’overall satisfaction’ and in 38 questions which can be summarized in 8 dimensions. An ordinal regression model which is also known as the proportional odds model is used to analyse the ordinal scaled rating of the dealers. The ordinal regression model is a well examined method in econometric theory, but many authors prefer using a linear regression model due to better interpretation, even the assumptions of a linear regression do not fit the data. Since the estimated coefficients of an ordinal regression model can not be properly interpreted we show other methods for a better insight of the relationship of the...

Mapping preferences for the restoration of environmental damage caused by illegal dumping
Provedor de dados: 31
Autores: Campbell,   Danny; Sinclair,   Victoria.
In this paper we use a discrete choice experiment to elicit the economic benefits associated with restoring environmental damage caused by illegal dumping activities. Our study focuses on an extensive rural upland area close to Belfast, where illegal dumping activities are prevalent. Using a random parameters logit model to account for unobserved taste heterogeneity, we exploit the panel nature of the dataset to retrieve partworths, or willingness to pay (WTP) values, for every individual in the sample. We subsequently investigate the existence of spatial dependence of these estimates. As a means of benefit transfer, we also employ geostatistical methods to extend across the whole of the study area the WTP estimates derived from the collected data. The...

The Dynamics of Food Stamp Program Participation: A Lagged Dependent Variable Approach
Provedor de dados: 31
Autores: Atasoy,   Sibel; Mills,   Bradford F.; Parmeter,   Christopher F.
This paper investigates the existence of Food Stamp Program (FSP) participation state dependence and its sources in by analyzing the dynamics of participation in the FSP using a lagged dependent variable approach. Results show that FSP receipt in the previous year is an important determinant of current FSP receipt. However, estimated persistence rates declined significantly after 1996, suggesting that long-term FSP dependency was reduced following broader welfare reform measures. The source of FSP state dependence among low-income households is mostly structural implying that a welfare trap does exist.

Job Instability and Family Planning: Insights from the Italian Puzzle
Provedor de dados: 31
Autores: Sabatini,   Fabio.
This paper carries out an investigation into the socio-economic determinants of couples’ childbearing decisions in Italy. Since having children is in most cases a “couple matter”, the analysis accounts for the characteristics of both the possible parents. Our results do not support established theoretical predictions according to which the increase in the opportunity cost of motherhood connected to higher female labour participation is responsible for the fall in fertility. On the contrary, the instability of the women’s work status (i.e. their being occasional, precarious, and low-paid workers) reveals to be a significant dissuasive deterrent discouraging the decision to have children. Couples with unemployed women are less likely to plan childbearing as...

Analyzing Landowner Demand for Wildlife and Forest Management Information
Provedor de dados: 31
Autores: Munn,   Ian A.; Hussain,   Anwar; West,   Ben; Grado,   Stephen C.; Jones,   W. Daryl.
Determining appropriate topics and target audiences is essential to design effective educational outreach programs.  Based on landowner responses to a mail survey, we determined both the importance and the availability of wildlife and forest management information topics to Mississippi landowners.  Combining this information clearly identified the appropriate subject matter for outreach programs-topics important to landowners and for which information was relatively unavailable.  The importance of wildlife and forest management information relative to its availability depended on the region, land use patterns, and landowner characteristics, thus demonstrating which segments of the population should be targeted to maximize program impact.

Household's Choice of Fuelwood Source in Malawi: A Multinomial Probit Analysis
Provedor de dados: 31
Autores: Jumbe,   Charles B.L.; Angelsen,   Arild.
This paper addresses the following question: What determines household's choice of fuelwood collection source? We address this question by estimating the multinomial probit model using survey data for households surrounding Chimaliro and Liwonde forest reserves in Malawi. After controlling for heterogeneity among households, we find strong substitution across fuelwood sources. Attributes of the fuelwood sources (size and species composition) and distance to them are the most important determinants of fuelwood choice. Further results show that customary forests generate environmental benefits by reducing pressure on both plantation forests and forest reserves. These findings support the need to focus more on community forests in national forest policies,...

The demand for health: differences between the native Dutch and immigrants in the Netherlands
Provedor de dados: 31
Autores: Cornelisse-Vermaat,   Judith R.; Maassen van den Brink,   Henriette.
This paper estimates the demand for health by using a health capital model for different population groups (native Dutch, Surinamese/Antillean, Moroccan, and Turkish) in the Netherlands. Also the effect of overweight on health utility is investigated. We found a decrease in the demand for health for age, overweight, and smoking, we found an increase in the demand for health for level of education and marital status. The analyses show a strong effect of gender. Being female in all groups is negatively related to health utility. Turkish and Moroccan ethnicity is negatively related to health status.
