Using a group identity manipulation we examine the role of social preferences in an experimental one-shot centipede game. Contrary to what social preference theory would predict, we fnd that players continue longer when playing with outgroup members. The explanation we provide for this result...

Missing data is a major problem in empirical development economics, as it may entail efficiency losses as well as biased results. This is an issue within the literature that investigates the effect of foreign aid on welfare. Using multiple imputation techniques, we address these problems and...

The market selection hypothesis posits that over time more successful traders will stay in the market, whereas those with trading losses will exit. If success is at least somewhat determined by behavior, then as a result of market selection traders who survive in markets behave differently than...

In general, linear multivariate rational expectations models do not have a unique solution. This paper reviews some procedures for determining whether there exists a solution, whether it is unique, and infers on the dimension of indeterminacy and the number of free parameters in a...

This paper presents a generalised framework to understand mixed-strategy sales behaviour with informative advertising. By introducing competition in the utility space into a clearinghouse sales model, we oer a highly tractable framework that can i) provide a novel welfare analysis of...

Mispricing (the dierence between prices and their underlying fundamental values) is an important characteristic of markets. The literature on the topic consists of many dierent measures. This state of aairs is unsatisfactory, since dierent measures may produce dierent results. Stockl et al....

We explore in an equilibrium framework whether games with multiple Nash equilibria are easier to play when players can communicate. We consider two variants, modelling talk about future plans and talk about past actions. The language from which messages are chosen is endogenous, messages are...

It is shown that the discrete-time version of the neoclassical one-sector optimal growth model with endogenous labor supply and standard assumptions on technology and preferences admits periodic solutions of any period as well as chaotic solutions. Solutions with period 2 are possible for any...

The well-known double marginalization problem understates the inefficiencies arising from vertical relations in consumer search markets where consumers are uninformed about the wholesale prices charged by manufacturers to retailers. Con- sumer search provides a monopoly manufacturer with an...

We study vertical relations in markets with consumer and retailer search. Retailers search to learn manufacturers' prices. We obtain three important new results. First, we explain why empirical distributions of retail prices are bi- modal, with a regular price and a sales price. Second, under...
