Based on an econometric analysis of the data obtained from a survey of meat plants ( ) in Iowa in summer 2007, this paper identifies the factors impacting the meat plants’ voluntary adoption of forward and backward traceability activities. The results suggest that the ownership type (corporate versus independent) and operations type (slaughtering versus not) matter rather than the size and meat type produced (beef, pork, or poultry) as suggested in the previous surveys. Furthermore, food safety activities appear to be complementary to traceability activities. The findings may assist ongoing regulatory efforts in implementing traceability in U.S. in the near future.

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...

The study investigates determinants of affiliation with the two strongest associations in Czech agriculture. These represent Agricultural Association grouping large-scale enterprises and Association of Private Farmers, respectively. Our objective is to analyze whether associations with different types of members (large-scale enterprises vs. private farmers) experience different motives for joining or lapsing. Moreover, we investigate if there are characteristics of the associations' members which positively correlate to membership. The results imply that political lobbying is the main entry incentive for both large-scale enterprises and individual farmers. Informal information exchange is a more significant motivation for private farmers than for...

The paper examines the joint adoption of conservation tillage, crop rotations, and soil testing by small and limited-resource farmers in the Southeast. The objectives are to determine the potential eligibility of small farmers for the Conservation Security Program, examine socioeconomic factors affecting adoption, and assess the interdependence between adopting different conservation practices. Results indicate that conservation management, ethnicity, and farm characteristics affect practice adoption. Of the producers surveyed in the study, 7% meet Conservation Security Program eligibility requirements, while the other 93% have less than a 20% likelihood of adopting the needed practices to qualify.

Reasons for Adopting Precision Farming: A Case Study of U.S. Cotton Farmers

Pandit, Mahesh; Mishra, Ashok K.; Paudel, Krishna P.; Larkin, Sherry L.; Rejesus, Roderick M.; Lambert, Dayton M.; English, Burton C.; Larson, James A.; Velandia, Margarita M.; Roberts, Roland K.; Kotsiri, Sofia.

We used survey data collected from cotton farmers in 12 southern U.S. states to identify factors influencing cotton farmers’ decisions to adopt precision farming. Using a seemingly unrelated ordered probit model, we found that younger, educated and computer literate farmers chose precision farming for profit reason. Farmers who perceived precision farming to be profitable adopt it to be at the forefront of agricultural technology. We also found that farmers who were concerned with environment emphasize precision farming adoption as a reason to improve environmental quality. Our results also indicate that farmers in coastal states such as Alabama, Mississippi, and North Carolina chose environmental benefits as a reason for precision farming technology...

In many developed countries, the share of wage employment out of the total agricultural labour force has been increasing for the last ten years. Using data from French agricultural censuses, we present an analysis of the factors that influence households' decisions about whether to work on the family farm or to work outside, and about the use of wage labour. Studying how the effects of these factors have varied between 1988 and 2000 enables us to highlight the different mechanisms that have led to an increase in permanent wage employment during that period. In particular, we show that family labour and permanent wage labour have become nearly equivalent in 2000, whereas that was not the case in 1988.

This article assesses the relative importance of risk preferences and rainfall availability on households’ decision to engage in off-farm employment. Devoting time for off-farm activities, while it helps households earn additional incomes, involves a number of uncertainties. Unique panel data from Ethiopia which includes experimentally generated risk preference measures combined with longitudinal rainfall data is used in the analysis. An off farm participation decision and activity choice showed that both variability and reduced availability of rainfall as well as neutral risk preferences increase the likelihood of off-farm participation. From policy perspective, the results imply that expanding off farm opportunities could act as safety nets in the face...

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

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...

Households’ WTP for the Reliability of Gas Supply

Chou, Wan-Jung; Bigano, Andrea; Hunt, Alistair; La Branche, Stephane; Markandya, Anil; Pierfederici, Roberta.

The security of natural gas supply is an important issue for all EU countries due to the region’s heavy dependence on imported supply sources and in light of energy demand for gas that is continuously increasing. Discussions have emphasised strategies for securing the supply at the macro level, e.g. diversification in supply sources, increase in storage capacity, etc. By contrast, consumers’ demand for the reliability of gas supply is rarely investigated. Hence this study was conducted to examine the economic implications associated with the security of gas supply directly to domestic consumers. Based on the choice experiment approach, household surveys were conducted in France, Italy and the UK. The results confirmed that the degree of the economic impact...

In this article we test whether in Italy the off-farm participation decisions of household members in working age are taken jointly and what are the variables that affect them. We find that the decisions of the operator, the spouse and the eldest child are not joint. Conversely, the participation decision of the operator and the spouse, that is of the two household's members belonging to the same generation, are found to be joint. The results suggest that policy actions for the purpose of encouraging off-farm participation rely on measures geared at improving the level of education and providing childcare services.

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...

Moser, Riccarda; Raffaelli, Roberta; Notaro, Sandra.

In recent years, concerns for potential risks on human health related to the overuse of chemical pesticides have encouraged research of alternatives production methods as integrated pest management (IPM) and organic agriculture. Consumer preferences for these practices or for new product characteristics often have been evaluated using stated preference techniques such as Choice Experiment (CE). Nevertheless, it has been found that in these surveys respondents generally report higher hypothetical than real willingness to pay, providing the existence of the so-called “hypothetical bias”. While the presence of this bias has been widely reported in Contingent Valuation, its investigation in CE is still at the beginning. Moreover, in most of the cases, the...

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...

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.

There is evidence that consumers are increasingly purchasing food directly from local producers, but little is understood about which market-specific, intrinsic, extrinsic, and demographic attributes influence the probability of preferring to purchase fresh produce through direct-market channels. A multinomial logit model is used to analyze a national dataset of fresh produce consumers with a focus on exploring differences among those that prefer to purchase direct always, occasionally (seasonally and as a secondary source), and never. Results suggest that to increase patronage and loyalty of current customers, producers may emphasize the availability of fresh, superior, vitamin-rich, and locally-grown produce at market locations through booth displays,...

Testing heterogeneous anchoring and shift effect in double-bounded models: The case of recreational fishing in Tasmania

Jennings, Sarah; Yamazaki, Satoshi; Lyle, Jeremy.

This paper explores the extent and nature of anchoring and shift effects in a double-bounded contingent valuation of recreational fishing in Tasmania’s inshore saltwater fishery. In particular we model the situation where respondents, when answering the second valuation question, evaluate the bid amount partly with reference to the size of the first bid amount. The estimates of the coefficients and mean WTP for a day of fishing are compared across different contingent valuation models, including a single-bounded model, a conventional double-bounded model and models that control anchoring and exogenous shift effects in both homogeneous and heterogeneous forms. Overall we find consistent evidence of anchoring, but mixed evidence of a shift effect. Results...
