| Throughout recent year food quality standards have become a ubiquitous phenomenon that nationally and globally influences agri-food markets. With equilibrium models commonly used in the quantitative analysis of market and trade effects, we review possible approaches to modeling standards existent in the literature, elaborate the reasoning behind them and discuss their suitability to reflect "real world" situations. While the modeling approaches identified may respectively depict a specific situation, they may not be appropriate in others. That is they capture certain effects of standards only. With increasing ability to account for the various effects of standards, the modeling approaches become more complex and the data requirements increase. |

| The assumption of independence of irrelevant alternatives in a sequential contingent valuation format should be questioned. Statistically, most valuation studies treat nonindependence as a consequence of unobserved individual effects. Another approach is to consider an inferential process in which any particular choice is part of a general choosing strategy of a survey respondent. A stochastic model is suggested, consistent with the reflexivity, transitivity, and continuity axioms of utility analysis. An application of this theoretical model to the valuation of watershed ecosystem restoration demonstrates that an empirical model recognizing reflexivity and transitivity, and also allowing for continuity, shows the highest in-sample predictive ability. |
