We explore risk sharing patterns among European Community (EC) countries and among OECD countries during the period 1966-90. We find that, for OECD as well as for EC countries, about 40 percent of shocks to GDP are smoothed at the one year frequency, with about half the smoothing achieved...

We study the politics of intergenerational redistribution in an overlapping-generations model with short-lived governements. The successive governements -who care about the welfare of the currently living generations and possibly about campaign contributions- are unable to pre-commit the future...

This study explains the evolution of wage inequality over the last 30 years and supports this explanation with evidence. At each level of schooling, a faster rate of technological progress weakens the link between schooling and work and increases the unknown needed to cope with during one's...

The paper studies the effects of mass immigration from the former USSR to Israel in the 1990s on the employment of the native-born. The exogeneity and the size of this inflow make it a "natural experiment'' of macroeconomic proportions. An open-economy model is used to analyze this experience,...

Foreign direct investment (FDI) is observed to be a predominant form of capital flows to emerging economies, especially when they are liquidity-constrained internationally during a global financial crisis. The financial aspects of FDI are the focus of the paper. We analyze the problem of...

We asked subjects to self-select into one of two constests, "coin" or "die." The winner in each of the contest is the person with most correct guesses of 20 coin flips or 20 rolls of a die, respectively. Most subjects reported that they belived that most people would go to the "coin" group. They...

We study the Nash bargaining solution of a problem in which two agents bargain over an uncertain outcome. Under the assumptions of risk neutrality and of constant absolute risk aversion, we study the way that solution varies, ex ante, when we vary the beliefs of one agent. Changing an agent`s...

This paper proposes a procedurally rational solution concept for two-person extensive-form games with complete information. The solution concept is based on the observation that the ex-post justifiability of choices is often a primary concern for decision-makers, especially in organizations. The...

We study a coordination game with randomly changing payoffs and small frictions in changing actions.

Debates often serve as intitutions of mechanisms for resolving conflicts and making decisions. In this paper , we present a simple model in order to explain two phenomena concerning debate rules.
