I present a model in which individuals compete for a prize by choosing to apply or not. Abilities are private information and in attempt to select the best candidate, the committee compares applicants with an imperfect technology. The choice of application cost, size of the prize and use of...

In this paper, we document that households' consumption expenditures crucially depend on their expected earnings - even after controlling for realized earnings, wealth and time-invariant unobserved characteristics such as permanent income and over-confidence. To explain this evidence, we develop...

In models of sequential decision making herd behaviour occurs if the signals smart(dumb) agents receive are (un)correlated and if agents have reputational concerns. We show thatintroducing costly effort to become informed about project payoffs (i) eliminates herdbehaviour and (ii) shifts...

This paper argues that the introduction of a short-sale constraint in the Arrow-Radner frameworkinvalidates standard definitions of complete and incomplete markets. In this constrained set-up,two threshold values with familiar properties arise.The case of a zero short-sale bound set on some...

The paper studies information processing imperfections in a fully rational decision-making network. It is shown that imperfect information transmission and imperfect information acquisition in a multi-stage selection game yield information overload. The paper analyses the mechanisms responsible...

Firms signal high quality through high prices even if the market structure is highly competitive and price competition is severe. In a symmetric Bertrand oligopoly where products may differ only in their quality, production cost is increasing in quality and the quality of each firm’s product...

In this paper, we document that households' consumption expenditures depend on their expected earnings - even after controlling for realized earnings and wealth. To explain this evidence, we develop and structurally estimate a standard-incomplete markets model in which rational households...
