Efficient Consumer Altruism and Fair Trade Products

Consumers have shown a willingness to pay a premium for products labeled as “FT” and a preference for retailers that are seen to be more generous to their suppliers/employees. A FT product is essentially a bundle of a base product and a donation to the supplier (e.g., a coffee farmer). An altruistic rational consumer will only choose this bundle if doing so is less expensive than buying the base product and making a direct donation. For FT to be sustainable either in a competitive equilibrium or in a monopolistic environment this bundling must yield an efficiency. This efficiency is generated in the following context. A supplier’s investment reduces the retailer’s cost or boosts the final product’s quality, but this investment is not immediately observable and cannot be enforced, hence there exists a moral hazard problem. In this environment, the altruism of the consumer can facilitate a more efficient contract: by paying the supplier more the retailer can both extract more consumer surplus and increase the level of contracted investment, while preserving the supplier’s incentive compatibility constraint. We assess our model in the context of the coffee industry.

An improved bootstrap test of stochastic dominance

We propose a new method of testing stochastic dominance that improves on existing tests based on the standard bootstrap or subsampling. The method admits prospects involving infinite as well as finite dimensional unknown parameters, so that the variables are allowed to be residuals from nonparametric and semiparametric models. The proposed bootstrap tests have asymptotic sizes that are less than or equal to the nominal level uniformly over probabilities in the null hypothesis under regularity conditions. This paper also characterizes the set of probabilities so that the asymptotic size is exactly equal to the nominal level uniformly. As our simulation results show, these characteristics of our tests lead to an improved power property in general. The improvement stems from the design of the bootstrap test whose limiting behavior mimics the discontinuity of the original test’s limiting distribution.
