This study adopts a discrete choice modelling methodology to evaluate individuals’ preferences over planning alternatives for an urban site of environmental interest. Since such projects involve some uncertainty and irreversibility, a special attention is devoted to the estimation of the quasi-option values which are associated to project development. Two distinct measures for the quasi-option value are estimated, and both coefficients indicate that the public places a significant value on reduction of the possibility of adverse irreversible effects: a more prudent development strategy is valued about four times more than a procedure that provides a lesser hedge against undesired outcomes. Furthermore, the study involved elicitation of intertemporal...

In this paper we compare results from an in-store field experiment and a mail survey choice experiment (CE) to investigate CE’s capacity in predicting grocery store market share. For the comparison, we used three seafood products: freshwater prawns, marine shrimp, and lobster. CE estimates were obtained via four econometric models: the conditional logit, the random parameter logit, the heteroskedastic extreme value, and the multinomial probit. We found that the level of control in the grocery store experiment and the choice of econometric model influenced the capacity of CE to predict grocery store market shares.

An Evaluation of Factors Affecting the Choice of Coastal Recreational Activities

Paudel, Krishna P.; Caffey, Rex H.; Devkota, Nirmala.

A visitor’s decision to use a particular recreational site is influenced by the individual’s taste as well as the characteristics of the site. For this reason, improved knowledge of the visitors’ interests and factors influencing their choices are vital for both planning and policy formulations in coastal development. This study examines visitor characteristics and desired site specific characteristics in order to determine the factors affecting use of the Louisiana coast for specific recreational purposes. We use a multinomial logit model and internet survey data to evaluate the factors affecting individuals’ decisions to visit coastal Louisiana for a specific use. Results suggest that the major variables affecting the choice of coastal recreational...

Are Consumers in Developing Countries Willing-to-Pay More for Micronutrient-Dense Biofortified Foods? Evidence from a Field Experiment in Uganda

Chowdhury, Shyamal K.; Meenakshi, J.V.; Tomlins, Keith; Owori, Constance.

Vitamin A deficiency is a major health problem in Africa and in many other developing countries. Biofortified staple crops that are high in pro vitamins A and adapted to local growing environment have the potential to reduce the prevalence of vitamin A deficiency. One such example is the orange-fleshed sweetpotato. However because of its distinctive orange color, which is in contrast to the white varieties that are typically consumed in Africa, it is important to assess whether consumers will accept it. It is this question that this paper attempts to address, using a choice experiment with the real product to quantify the magnitude of the premium or discount in consumers’ willingness to pay that may be associated with it. In addition, it also considers...

The urgent need to improve livestock productivity in sub-Saharan Africa in order to keep pace with expected increases in demand for meat and milk is very topical. Breed improvement provides key entry points for increasing productivity in cattle populations. However, there are tendencies for breed improvement programs to focus on single, market driven traits such as milk or meat production in isolation of environmental constraints and broader livestock system functions which cattle assume in developing countries. This potentially leads to genotypes that are not well adapted to the environment and not capable of performing the multiple roles that cattle assume in cattle production systems of developing countries. In developing countries, many important...

Steiner, Bodo E.; Yang, Jun.

Following the May 2003 Canadian BSE case, food safety issues have become even more prominent to policymakers and consumers. In both Canada and the US, governments and industry have responded with a variety of quality assurance, traceability and labeling schemes. However, there is little information available on the extent to which consumer perceptions differ regionally across North America towards labeling schemes. This paper attempts to fill this gap, by providing results on a variety of beef labeling strategies from choice experiments that were conducted in Alberta (Canada) and Montana (US). The analysis focuses on consumers' perceptions towards negative voluntary labeling with regard to BSE testing, genetically modified organisms (GMO) and the use of...

Carbon Mitigation Costs for the Commercial Sector: Discrete-Continuous Choice Analysis of Multifuel Energy Demand

Newell, Richard G.; Pizer, William A..

We estimate a carbon mitigation cost curve for the U.S. commercial sector based on econometric estimation of the responsiveness of fuel demand and equipment choices to energy price changes. The model econometrically estimates fuel demand conditional on fuel choice, which is characterized by a multinomial logit model. Separate estimation of end uses (e.g., heating, cooking) using the 1995 Commercial Buildings Energy Consumption Survey allows for exceptionally detailed estimation of price responsiveness disaggregated by end use and fuel type. We then construct aggregate long-run elasticities, by fuel type, through a series of simulations; own-price elasticities range from -0.9 for district heat services to -2.9 for fuel oil. The simulations form the basis of...

Campbell, Danny.

This paper reports the findings from a discrete choice experiment study designed to estimate the economic benefits associated with rural landscape improvements in Ireland. Using a mixed logit model, the panel nature of the dataset is exploited to retrieve willingness to pay values for every individual in the sample. This departs from customary approaches in which the willingness to pay estimates are normally expressed as measures of central tendency of an a priori distribution. In a different vein from analysis conducted in previous discrete choice experiment studies, this paper uses random effects models for panel data to identify the determinants of the individual-specific willingness to pay estimates. In comparison with the standard methods used to...

Prices for nearly all basic commodity rose at unprecedented rates throughout early 2008, only to fall nearly as fast as financial markets and global economies began to collapse. Rising food prices in 2008 led to concerns that commodity price spikes would lead to more general food inflation, but by early 2009 interest focused more on the seeming inability of food prices to fall back down with commodity prices. This study provides an empirical investigation into the pass-through of commodity prices to retail prices for two different types of food products: potatoes and fluid milk. The results show that pass-through depends on the nature of the food in question, but is generally consistent with theoretical models of pricing by sellers of multiple,...

European statistics show that one of the most widespread source of health risks related to food is mycotoxins. The objective of this paper is to evaluate the Italian consumers’ perception of the mycotoxins’ risk and, more specifically, their willingness-to-pay (WTP) for a hypothetical bottle of milk obtained by cows in which the feed ration contains maize certified for the ‘good practices’ that reduce such risk. For this purpose, a web-based stated choice (SC) experiment involving a representative sample of 973 Italian consumers has been carried out and WTP has been measured using the panel data version of a Random Parameters Logit (RPL) model. The results show that Italian consumers are willing to pay a rather high average price premium for...

Although livestock forms a very important component of the livelihoods of rural populations of developing countries, productivity remains very low. Livestock keepers are beset by various constraints. In sub-Saharan Africa, cattle are exposed to a number of tropical diseases and other environmental stresses. Breed improvement programs provides key entry points for increasing productivity in cattle populations, especially those plagued by animal diseases. However, breed improvement programs have tended to focus on single, market-driven production traits in isolation of broader livestock system functions. This potentially leads to genotypes that are not well adapted to the environment and not suitable for performing the multiple roles of cattle in developing...

This contribution is based on the notion that different technologies are present in an industry. These different technologies result in differential “drivers” of economic performance depending on the kind of technology used by the individual firm. In a first step different technologies are empirically distinguished. Subsequently, the associated production patterns are approximated and the respective change over time is estimated. A latent class modelling approach is used to distinguish different technologies for a representative sample of E.U. dairy producers as an industry exhibiting significant structural changes and differences in production systems in the past decades. The production technology is modelled and evaluated by using the flexible functional...

When different technologies are present in an industry, assuming a homogeneous technology will lead to misleading implications about technical change and inefficient policy recommendations. In this paper a latent class modelling approach and flexible estimation of the production structure is used to distinguish different technologies for a representative sample of E.U. dairy producers, as an industry exhibiting significant structural changes and differences in production systems in the past decades. The model uses a transformation function to recognize multiple outputs; separate technological classes based on multiple characteristics, a flexible generalized linear functional form, a variety of inputs, and random effects to capture firm heterogeneity; and...

Facilitating healthy eating among young people, particularly among minorities who are at high risk for gaining excess weight, is at the forefront of current policy discussions and food program reviews. We investigate the effects of social interactions and relative prices on fruit and vegetable consumption by African American youths using rich behavioral data from the Family and Community Health Study and area-specific food prices. We find the presence of endogenous effects between a youth and parent, but not between a youth and friend. Lower relative prices of fruits and vegetables tend to increase intakes. Results suggest that health interventions targeting a family member may be an effective way to increase fruit and vegetable intake by African Americans...

This study estimates the effects of an urban growth boundary (UGB) on land development decisions in Knox County, TN, using a heteroscedastic probit model. With combined efforts of increased land development within the city boundary and decreased development within the UGB and the neighboring town of Farragut after the implementation of UGB, the UGB of Knox County has been successful in urban revitalization within the city boundary and discouraging urban sprawl. These UGB impacts may be related to the city government having the right to annex land parcels within the UGB without consent of land owners.

Estimating the Amenity Costs of Global Warming in Brazil: Getting the Most from Available Data

Timmins, Christopher.

This paper develops a theoretically consistent technique for valuing non-marketed local attributes using compensating income differentials in the absence of housing market data. The individuals indirect utility function is identified with aggregate data describing equilibrium location decisions, and this function is used in place of the unidentified equation describing how housing prices are determined. The model is used to value climate amenities in Brazil, where such data problems are prevalent. Similar problems arise in other developing countries, particularly when one looks outside of the largest cities.
