Comparison of Perception of Risk and Willingness to Consume GM Foods AgEcon
Wachenheim, Cheryl J.; Nganje, William E.; Lesch, William C..
The dichotomy between perceptions of the acceptability of risk associated with genetically modified (GM) foods and willingness to consume GM foods is investigated. Results indicate that some consumers are willing to consume GM foods even though they may perceive such foods as somewhat unsafe, with determinants such as self-perceived knowledge about the availability of GM foods and altruistic motives having positive and significant impacts on their consumption decision. Efforts towards decreasing perceptions of risk and ultimately increasing acceptance of, and demand for, GM foods should address issues related to their altruistic characteristics and outrage.

Beef Labeling After BSE: Do Consumers Care about BSE Testing and GMO Labeling? Evidence from Canada and the US AgEcon
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...

Labor Market Participation of Chinese Agricultural Households AgEcon
Glauben, Thomas; Herzfeld, Thomas; Wang, Xiaobing.
This work is devoted to the analysis of the different labor market participation regimes of Chinese farm households. Using household data over the period 1986-2000 from the province Zhejiang, we apply a multinomial logit model to empirically examine household, farm, and regional characteristics affecting the probability that farmers employ one of four alternative labor market regimes. Results suggest that labor market decisions are significantly related to several personal, farm, and village attitudes. In addition, we find the more market oriented policy reforms at the end of the 1980s stipulated that households participate in labor markets while the more anti-market reforms during the 1990s led to the opposite and encouraged autarky.

An Evaluation of Factors Affecting the Choice of Coastal Recreational Activities AgEcon
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...

Farming and the Internet: Reasons for Non-Use AgEcon
Briggeman, Brian C.; Whitacre, Brian E..
Rural broadband infrastructure and service has received a significant amount of funding through the American Recovery and Reinvestment Act of 2009. These funds should increase broadband availability, but will broadband be used in rural areas and in particular by farmers? This paper uses Agricultural Resource Management Survey data to investigate why the majority of U.S. farmers choose not to use the Internet in their farm business. Although frequently cited by policymakers, concerns about inadequate Internet service or security actually account for a small percentage of responses. This research identifies targeted educational programs that focus on alleviating perceived barriers to Internet use.

Growth of German dairy farms under the EU milk quota AgEcon
Breustedt, Gunnar; Mees, Martin.
We estimate determinants of growth among German dairy farms between 1997 und 2005 under the EU milk quota system. Higher milk yield per cow, more family labour, and higher milk prices increase the growth rate of growing farms, ceteris paribus. Older growing farmers tend to grow at lower rates. In line with Weiss’ findings (1999) for Austrian farms, Gibrat’s Law of relative firm growth being independent of initial firm size does not hold for our subsample of farms growing in milk production, either: the growth rate is quite high for small farms and has a minimum for farms around 325,000 kg of initial quota. For the 16% of growing farms that have more initial quota the growth rate increases up to some out-of-sample maximum. We corrected for selection bias by...

Farm Operator Benefits from Direct Marketing Strategies: How Does Local Food Impact Farm Financial Performance? AgEcon
Park, Timothy A.; Mishra, Ashok K.; Wozniak, Shawn J..
In the era of a global economy, farmers face increasing pressure in developing a portfolio of various marketing channels. However, the literature on direct marketing strategies has mainly focused on consumers. Using farm-level data this study investigates factors associated with the choice of three direct marketing strategies. We apply a selectivity based approach for the multinomial logit model to assess the relationship between the choice of direct sales marketing strategy on the financial performance of the business. Findings from this study suggest that obtaining an Internet connection and accessing the Internet for farm commerce increases the likelihood of using intermediated marketing outlets. Using the Internet for farm commerce and operating...

A TWO-STAGE MODEL OF THE DEMAND FOR SPECIALTY CROP INSURANCE AgEcon
Knox, Lyle; Richards, Timothy J..
Legislators are considering raising catastrophic (CAT 50% coverage) crop insurance premiums. However, estimates of a two-stage coverage-choice and participation model using county-level data from California grape growers show that the demand for CAT insurance is price-elastic, therefore, premium increases will worsen the financial performance of the grape-insurance program.

THE EFFECT OF PERSONAL AND FARM CHARACTERISTICS UPON GRAIN MARKETING PRACTICES AgEcon
Sartwelle, James D., III; O'Brien, Daniel M.; Tierney, William I., Jr.; Eggers, Tim.
A survey of Kansas, Texas, and Iowa agricultural producers was taken to examine the factors affecting their grain marketing practices. Sales indices models and models of qualitative choice are used to determine whether marketers' choices of cash market, forward contract, or futures and options oriented marketing practices are significantly affected by their personal farm business characteristics. Results indicate that geographic location, farm size, grain enterprise specialization, farming experience, use of grain storage, and use of crop insurance have significant effects upon the respondents' choice of grain marketing practices.

ANALIZING WATER FRAMEWORK DIRECTIVE IMPACTS USING A MULTINOMIAL LOGIT LAND USE MODEL AgEcon
Fezzi, Carlo; Bateman, Ian J.; Day, Brett H.; Posen, Paulette; Rigby, Dan.
We develop a two-stage, multinomial logit model of UK land use to investigate the impact of policy changes upon agriculture. The model utilizes a large panel database covering the entirety of England and Wales for 14 years between 1969 and 2004 integrated with the economic and physical environment determinants of all major agricultural land use types. Our model performs well in out-of-sample prediction of current land use and we use it to assess a proposed implementation of the Water Framework Directive via a tax on fertilizer. Results indicate that such policy change would generate substantial switching from arable to grassland systems, reducing significantly the amount of nitrate leaching into UK water-bodies.

THE IMPACT OF PROMOTION AND ADVERTISING: A LATENT CLASS APPROACH AgEcon
Richards, Timothy J..
Typically, marketers define market segments by their demographic characteristics, assuming that these segments represent consumers with relatively homogeneous buying patterns. A more managerially useful definition, however, groups consumers of similar behavior directly and then seeks to find demographic commonalities among them. This study uses a latent class analysis technique to segment consumers based on their responsiveness to a set of marketing variables, finding that a multiple-segment model provides a better fit to the data, and that these segments differ significantly in their responsiveness. By targeting marketing activities to their most responsive segments, the efficiency of commodity promotion can be dramatically improved.

Governance Control Mechanisms in Portuguese Agricultural Credit Cooperatives AgEcon
Cabo, Paula; Rebelo, Joao.
Over the last decade Portuguese Agricultural Credit Cooperatives (ACCs) have increasingly face survival challenges related to their difficulty in gathering equity. The main source of ACCs equity is the net benefit; thus, understanding how ACCs governance can work on correcting bad economic performance is of crucial importance to overcome this constraint. The main objective of this paper is to describe the governance control mechanisms in the ACCs. Five governance mechanisms are identified: board and chairman change (internal mechanisms), central ACC intervention by an agent or by management board replacement and merger. Empirical analysis proved that the internal governance mechanisms activity is not related to the ACC performance. Additionally: (a) ACCs...

FACTORS INFLUENCING TECHNOLOGY ADOPTION IN A LOUISIANA AQUACULTURE SYSTEM AgEcon
Caffey, Rex H.; Kazmierczak, Richard F., Jr..
A multinomial logit model was estimated and used to analyze the impact of various producer characteristics on the adoption of flow-through and recirculating technology in soft-shelled crab production. Because of the industry's geographic isolation and high turnover rate, data was collected by personal interviews in 1991. The results suggest that increased adoption might be fostered by targeting education programs towards full time, family operated businesses in nontraditional production regions. However, development of effective education programs may be hindered by the lack of a significant relationship between producer adoption decisions and the information provided by university or extension personnel.

FSA Direct Farm Loan Program Graduation Rates and Reasons for Exiting AgEcon
Dixon, Bruce L.; Ahrendsen, Bruce L.; Nwoha, Ogbonnaya John; Hamm, Sandra J.; Danforth, Diana M..
Farm Service Agency (FSA) direct loans are intended to provide transitory credit to creditworthy borrowers unable to obtain conventional credit at reasonable terms. Farm loan program (FLP) effectiveness is measured in part by how readily direct loan borrowers graduate to conventional credit. A survey of FSA borrowers originating direct loans during fiscal years 1994-1996 is used to estimate graduation rates. A majority of 1994-1996 loan originators did exit the direct FLP by November 2004. A multinomial logit model indicates financial strength at origination resulted in greater likelihood of farming without direct loans approximately 9 years after loan origination.

Bayesian estimation of non-stationary Markov models combining micro and macro data AgEcon
Storm, Hugo; Heckelei, Thomas.
In this poster a Bayesian estimation framework for a non-stationary Markov model is developed for situations where sample data with observed transition between classes (micro data) and aggregate population shares (macro data) are available. Posterior distributions on transition probabilities are derived based on a micro based prior and a macro based Likelihood function thereby consistently combining previously separated approaches. Monte Carlo simulations for ordered and unordered Markov states show how observed micro transitions improve precision of posterior knowledge as the sample size increases.

Agricultural Input Market Segments: Who Is Buying What? AgEcon
Alexander, Corinne E.; Wilson, Christine A.; Foley, Daniel H..
For agribusiness managers and salespeople, understanding customers and their preferences and behaviors is crucial to success. This study uses cluster analysis to identify five distinct buyer segments for expendable input purchases for U.S. crop and livestock commercial producers. A multinomial logit model is used to predict segment membership based on demographic, behavioral, and business management factors. Results provide important information for agricultural input suppliers.

EXPLAINING THE CLIMATE-DEPENDENT DISTRIBUTION OF CROPS IN SPACE –THE EXAMPLE OF CORN AND CORN-COB-MIX IN BADEN-WÜRTTEMBERG AgEcon
Lippert, Christian; Chatzopoulos, Thomas; Schmidtner, Eva; Aurbacher, Joachim.
This article analyses the current climate-dependent spatial distribution of corn and corn-cob-mix in Baden-Württemberg using 2007 data at the county and community level. We use OLS and spatial econometric models to estimate the effects of different climate and non-climate variables on the share of grain maize in UAA. Whereas the temperature effect is missed by means of OLS regression, the adequate spatial error model at the county level yields a highly significant positive effect of mean annual temperature. Additionally, it displays a temperature cut-off point after which corn share is less likely to rise due to temperature increase. These effects are supported by a non-spatial multinomial logit model at the community level. The latter further indicates...

Assessing the Returns from Organic Marketing Channels AgEcon
Park, Timothy A..
Organic farmers face heightened pressure in developing a portfolio of different marketing channels and in bargaining competitively with increasingly sophisticated marketing participants in the supply chain for organic products. This research assists producers by identifying specific farm and demographic factors that enhance earnings given the choice of marketing outlet. The two significant selectivity coefficients confirm that organic earnings when marketing through a single outlet are biased upward since farmers who are better suited to market through multiple outlets have already moved away from this marketing strategy. An accurate evaluation of the projected earnings from any marketing strategy must account for selectivity effects.
