The paper studies the role of communication in facilitating collusion. The situation of infinitely repeated Cournot competition in the presence of antitrust enforcement is considered. Firms observe only their own production levels and a common market price. The price is assumed to have a...

A people's culture, norms and habits are important determinants not just of the quality of social life but of economic progress and growth. In this paper we take the view that while the importance of culture is undeniable, the innateness of culture is not. We work here with a single example and...

The paper analyses the interaction between economic incentives and work norms in the context of social insurance. If the work norm is endogenous in the sense that it is weaker when the population share of beneficiaries is higher, then voters will choose less generous benefits than otherwise. We...

We analyze the effect of deadlines on timing of effort when agents are occasionaly distracted. We show that agents precautiously work early when completion of the task is uncertain, but rather likely. Agents who are rarely distracted will always postpone effort since the risk of not completing...

We investigate experimentally how the share of experienced traders in double-auction asset markets affects trading, in particular the occurrence of bubble-crash pricing patterns. In each session, six subjects trade in three successive market rounds and gain experience. In a fourth round,...

We characterize pension systems along three dimensions: 1) actuarial vs. non-actuarial, 2) funded vs. pay-as-you-go, 3) defined-contribution vs. defined-benefit. Increasing the degree of actuarial fairness, by strengthening the linkage between contributions and benefits, reduces labor market...

We develop a model in which non-white individuals are defined with respect to their social environment (family, friends, neighbors) and their attachments to their culture of origin (religion, language), and in which jobs are mainly found through social networks. We find that, depending on how...

The Todaro Paradox states that policies aimed at reducing urban unemployment are bound to backfire: they will raise rather than reduce urban unemployment. The aim of this paper is to reexamine this paradox in the context of efficiency wage and search-matching models. For that, we study a policy...

We consider a search-matching model in which black workers are discriminated against and the job arrival rates of all workers depend on social networks as well as distance to jobs. Location choices are driven by the racial preferences of households (both blacks and whites) consciously choosing...

We find that reduced foreign corporate taxes may lead to inefficient foreign acquisitions if complementarities between foreign and domestic assets are low, and to efficient foreign acquisitions if such complementarities are high. Moreover, with large complementarities, foreign acquisitions can...
