This is the first paper on consumer search where the cost of going back to stores already searched is explicitly taken into account. We show that the optimal sequential search rule under costly second visits is very different from the traditional reservation price rule in that it is...

Entrusting the power to punish to a central authority is a hallmark of civilization. We study a collective action dilemma in which self-interest should produce a sub-optimal outcome absent sanctions for non-cooperation. We then test experimentally whether subjects make the theoretically optimal...

The sanctioning of norm-violating behavior by an effective formal authority is an efficient solution for social dilemmas. It is in the self-interest of voters and is often favorably contrasted with letting citizens take punishment into their own hands. Allowing informal sanctions, by contrast,...

Revealed preference theory o¤ers a criterion for decision-making quality: if decisions are high quality then there exists a utility function that the choices maximize. We conduct a large-scale ?eld experiment that enables us to test subjects?choices for consistency with utility maximization and...

Although (or because) it is uncommon to observe consumers bargaining at retail stores in the Western world, the circumstances under which retail rms are actually willing to bargain is largely unknown. We construct a theoretical model in order to better understand how price and rm characteristics...

We consider a discrete-time dynamic game in which a nite number of players extract a non-renewable resource and derive consumption solely from the extracted amount (cake-eating game). Markov-perfect Nash equilibria can be constructed in this game not only if the players have time-preference...

When consumers search sequentially for prices and product matches, their beliefs of what they will encounter at the next rm are important in deciding whether or not to continue to search. In search environments where retailers have a common cost that is not known to consumers and is either the...

This paper studies observational learning in a consumer search environment. In our model, consumers observe the purchasing decision of a predecessor before deciding which rm to visit. We show that if consumers emulate their predecessor and initiate their search at the rm she purchased from, a...

The underground economy expanded substantially during the late 1990s, both in the industrialized and the developing world. I argue that this development is a response to the sharp increase in market competition worldwide. I develop a parsimonious oligopoly model of free entry and free sector...
