We develop a model of common agency with complete information and general preferences with non-transferable utility, and prove that the principals'Nash equilibrium in truthful strategies implements an efficient action. We apply this theory to construct a positive model of public finance, where...

The allocation of talent in a society is an important determinant of productivity and growth. I study the informational role of education on the allocation of talent in a two-sector model where education provides workers information about their abilities. When workers and firms are equally...

We develop an OLG economy with accumulation in human capital. Heterogenity among individuals in each generation results mainly from the (random) innate ability assigned to each individual. We analyze how better information, which allows better 'screening' during the 'youth' period when the...

In an economy with asymmetric information, Rational Expectations Equilibria (REE) need not become asymptotically incentive compatible, even if many independent replicas of the economy are merged together. We identify a sub-class of REE for which this is nevertheless the case.

We generalize the economic decision problem considered by Blackwell(1953) in which a decision maker chooses an action after observing a signal correlated to the state of nature. Unlike Blackwell's case where the feasible set is fixed, in our framework, the feasible set of actions depends on the...

The new decade has been called "the age of information." We show that, although information has become more accessible, the increase in the variety of products has made consumers' choices complex and uncertain. Faced with uncertainty about products' attributes offered by "umbrella brands,"...

In this paper, we have emphasized information problems which lead to home bias and insufficient amounts of capital inflows.

The art of rhetoric may be defined as changing other people`s minds (opinions, beliefs) without providing them new information. One technique heavily used by rhetoric employs analogies. Using analogies, one may draw the listener`s attention to similarities between cases and to re-organize...
