We address the problem faced by innovators who have an idea for a marketable product but must hire employees to bring the product to the market. Information leakage implies that newly-hired employees become informed of the idea and may attempt to bring the product to the market themselves. We...

In this Paper we analyse the effects of information leakage on the incentives to innovate in firms. We analyse a situation in which an employee in a firm is inspired with a new idea for a product. In a framework in which Intellectual Property Rights on ideas are absent, we analyse the...

In this Paper, we provide an explanation of the democratic peace hypothesis, i.e., the observation that democracies rarely fight one another. We show that in the presence of information asymmetries and strategic complements, the strategic interaction between two democracies differs from any...

The phenomenon of choice shifts in group decision-making is fairly ubiquitous in the social psychology literature. Faced with a choice between a ‘safe’ and ‘risky’ decision, group members appear to move to one extreme or the other, relative to the choices each member might have made...

A model of group decision-making is studied, in which one of two alternatives must be chosen. While group members differ in their valuations of the alternatives, everybody prefers agreement to disagreement. Our model is distinguished by three features: private information regarding valuations,...

In this Paper we extend the cheap talk model of Crawford and Sobel (1982) to a multidimensional state space and policy space. We provide a characterization of equilibria. We focus on the question of feasibility of information transmission, for large degrees of conflict of interests between the...

In this paper we question the common wisdom that more polarized voters’ opinions imply larger policy polarization. We analyze a voting model in which the source of the polarization in voters’ opinions is “correlation neglect”, that is, voters neglect the correlation in their information...

In this paper we examine the long term effects of socialization and segregation in schools, on labour market outcomes. We incorporate a model of “informational” peer influence by which beliefs of pupils are affected by exposure to other pupils’ posterior beliefs. Specifically, we focus on...

This paper uses a new data set on domestic child adoption to document the preferences of potential adoptive parents over born and unborn babies relinquished for adoption by their birth mothers. We show that adoptive parents exhibit significant biases in favor of girls and against...
