In this paper, we try to understand what the main causes of food losses (FLs) are. Our results show that producers' education and experience number years in which a producer has been involved production specific crop are significantly correlated with reduction FL. Unfavorable climatic conditions, pests, diseases, as well limited knowledge access equipment, credit, markets, also challenges incre...

The utilitarian aggregation rule requires social utility and beliefs to be a convex combination of individual utilities beliefs, respectively. Since, in the case belief heterogeneity, standard Pareto condition is incompatible with such separate aggregation, new condition, called belief-proof proposed alleviate occurrences spurious agreement by restricting unanimity that can considered reasonabl...

Concern for individual consumption relative to per capita consumption can induce a fear of falling behind which increases precautionary savings. This fear intensifies as societal income growth increases, allowing for a positive effect of growth on savings rates. JEL classifications: E21, D11, D91.

This paper shows that even if all consumers face search costs, if these are below a certain level dependent upon the firm numbers and demand elasticity, the Diamond-type equilibrium with all prices at the monopoly level fails to exist. JEL Classification: D83, D11,

We consider preference relations over information that are monotone: more information is preferred to less. We prove that, if a preference relation on information about an uncountable set of states of nature is monotone, then it is not representable by a utility function. JEL Classification: C70, D11, D80

People are sometimes risk-averse in gains but risk-loving in losses. Such behavior and other anomalies underlying prospect theory arise from a model of local status maximization in which consumers compare their wealth with other consumers of similar wealth. This social explanation shares key features with the psychological explanation offered by Kahneman and Tversky. JEL Classification: D81, D11

The is applied to introduction New Dutch Retail Standard broiler market, standard on animal welfare initiated by private sector with national coverage. results show that this did not lower producer, retailer, and consumer welfare; rather, soc...

We show that a steeply increasing workload before a deadline is compatible with time-consistent preferences. The key departure from the literature is that we consider a stochastic environment where success of effort is not guaranteed. JEL Classification: D91, J22, D81, D11.

Marshallian consumer surplus (MCS) is generally an inaccurate measure of welfare change because it neglects income effects. Suppose these effects overturn the usual demand response to a price change. Then, the deadweight loss from a distortionary tax or subsidy has the wrong sign, that is, there is a spurious deadweight gain. JEL Classification: D11, D6.
