In light of the financial crisis and the empirical findings from behavioral economics, policymakers should reconsider the fundamental question: What is competition? Only in understanding competition can one understand what competition can or cannot achieve under certain circumstances. This...

One of the arguments against the Fair Trade scheme is that the guaranteed minimum price tends to depress world prices and thus the incomes of non-participating farmers (e.g. The Economist, 2006). We develop a model that distinguishes between the impact of the introduction of a Fair Trade market...

We study dynamic markets where product safety is unobserved by consumers. Perfect, but costly, audits and an exogenous noisy signal can provide information regarding seller type. Without the noisy signal, sellers do not disclose product safety without auditing. If audits are too expensive, a...

Firms use different instruments to convey product quality in order to counteract market failures due to lack of information on behalf of consumers. We will give a brief overview on the two main types of quality signals. Then an economic model is developed to determine which offers higher...

This paper shows that a monopolistic certifying party can have incentives to disclose revealing information about the agent he is certifying. Using a three-person game-theoretic model and allowing certificate users (buyers) to have noisy estimates of the quality level of the agent being...

There is an active debate about how to regulate electronic cigarettes, due to uncertainty about their health effects and whether they are primarily a quit aid or a gateway drug for combustible cigarettes. We model optimal e-cigarette regulation and estimate key parameters. Using tax changes and...
