Evaluating animal welfare with choice experiments: an application to Swedish pig production

Abstract

Abstract In this study, the demand for animal welfare attributes when buying pork fillet is investigated among Swedish respondents. The issue is of importance in order to ensure an economically viable pig industry while applying an increasing number of animal friendly practices. In order to obtain information about consumer demand, an indirect utility function and willingness to pay (WTP) for animal welfare attributes are estimated. The attributes are solely associated with animal friendly practices. An investigation of numerous housing and managerial practices of pig production has not yet been performed. The indirect utility function is estimated using a random parameter logit model. A realistic approach when modeling consumer choice is to allow for heterogeneity in preferences. The relevance of assuming randomness of some of the parameters is evaluated by using a specification test developed by McFadden and Train ( 2000 ). The WTP is also estimated at the individual level. The results indicate that WTP for animal welfare attributes may be negative or positive. The preferences are also heterogeneous among respondents, which may be explained by a segmentation of preferences. Finally, the WTP estimates for animal welfare practices are compared with cost estimates for such production systems. [Econlit subject codes: C010, C500, Q100] © 2008 Wiley Periodicals, Inc.
