Bargains or Rip-offs? Reference Price Effects in Conjoint Stated Demand AgEcon
Hu, Wuyang.
This study incorporates reference point effects into a stated choice survey of consumer demand for food with credence attributes. Parametric tests can be applied to the utility function to examine the existence of reference price effects. Results are consistent with prospect theory in that consumers exhibit strong and nonlinear reference price effects, with cheaper prices receiving less decision weight than higher prices. The underlying utility function is concave over lowered prices and convex over increased prices, with diminishing sensitivity in both domains. The study, however, did not find experience or consumers' attitudes to be significant in explaining reference price effects.

WTP and WTA for Non-GM and GM Food: UK Consumers AgEcon
Moon, Wanki; Balasubramanian, Siva K.; Rimal, Arbindra.
In a survey of UK consumers, we elicited their willingness-to-accept (WTA) a discount for GM foods and willingness-to-pay (WTP) a premium for non-GM foods in order to assess their valuation of the non-GM characteristic in food products. Mean WTA exceeds mean WTP, a finding that suggests the valuation of the non-GM characteristic reflects an endowment effect, imperfect substitutability between GM and non-GM foods, or both. Regression results show that perceived risks (benefits) associated with GM foods significantly increase (decrease) WTA and WTP estimates. Additional regression models using the difference between WTA and WTP as the dependent variable indicate that risk (benefit) perceptions increased (decreased) the discrepancy between WTA and WTP...

Willingness to Pay (WTP) a Premium for Non-GM Foods versus Willingness to Accept (WTA) a Discount for GM Foods AgEcon
Moon, Wanki; Balasubramanian, Siva K.; Rimal, Arbindra.
In a survey of UK consumers, we elicited their willingness to accept (WTA) a discount for GM foods and willingness to pay (WTP) a premium for non-GM foods in order to assess their valuation on the non-GM characteristic in food products. Mean WTA is found to exceed mean WTP, suggesting the valuation of the non-GM characteristic reflects an endowment effect, imperfect substitutability between GM and non-GM foods, or both. Regression results show that perceived risks (benefits) associated with GM foods significantly increase (decrease) WTA and WTP estimates. Additional regression models using the difference between WTA and WTP as the dependent variable indicate that risk (benefit) perceptions increased (decreased) the discrepancy between WTA and WTP...

Expected Utility or Prospect Theory Maximizers? Results from a Structural Model based on Field-experiment Data AgEcon
Bocqueho, Geraldine; Jacquet, Florence; Reynaud, Arnaud.
We elicit risk preferences of French farmers in a field experimental setting under expected utility theory and cumulative prospect theory. We use two different estimation methods, namely the interval approach and the estimation of a random preference model. On average, farmers are risk averse and loss averse. They also exhibit an inverse S-shaped probability weighting function, meaning that they tend to overweight small probabilities and underweight high probabilities. We infer from our results that CPT explains farmers’ behaviour better than EUT in the context of our experiment. We also investigate how preferences correlate with individual socio-demographic characteristics. We find that education and agricultural innovation are negatively linked with risk...

An Outcome-Oriented Theory of Choice and Empirical Paradoxes in Expected Utility Theory AgEcon
Kaneko, Fumihiro.
I analyze observed choice between lotteries from an outcome-oriented point of view in the framework of choice between random variables. I characterize a choice maker, who faces a choice situation between lotteries, by (1) a surmising process that associates, with a pair of lotteries, a set of well-defined choice situations between random variables, and (2) a choice set that is a collection of well-defined choice situations. I give a partial axiomatic foundation of the theory. The theory is applied to explain the well-known paradoxes in expected utility theory.

Do Fishermen Have Different Attitudes Toward Risk? An Application of Prospect Theory to the Study of Vietnamese Fishermen AgEcon
Nguyen, Quang; Leung, PingSun.
Field experiment and household survey data are combined to investigate whether working in a risky occupation such as fishing makes fishermen have different risk preferences than individuals in other occupations. Prospect theory is utilized as the main analytical framework and a structural model approach is developed to simultaneously correlate the parameters of the utility function under prospect theory with other socioeconomic variables. The key finding is that working in fishing makes economic agents less risk averse than others. Fishermen also tend to be less sensitive to probability weighting changes in the experiment. It is possible that fishermen have adapted to their unique environment by using specific heuristics for decision making under...

The Impact of Price-Induced Hedging Behavior on Commodity Market Volatility AgEcon
Kauffman, Nathan S.; Hayes, Dermot J..
The utility maximization problem of a grain producer is formulated and solved numerically under prospect theory as an alternative to expected utility theory. Conventional theory posits that the optimal hedging position of a producer is not affected solely due to changes in the level of futures prices. However, a strong degree of positive correlation is apparent in the data. Our results show that with prospect theory serving as the underlying behavioral framework, the optimal hedge of a producer is affected by changes in futures price levels. The implications of this price-induced hedging behavior on spot prices and volatility are subsequently considered.
