In my asymmetric-information model of layoffs, high-productivity workers are more likely to be recalled to their former employer and may choose to remain unemployed rather than to accept a low-wage job. In this case, unemployment can serve as a signal of productivity, and duration of...

The costs of vertical integration are analyzed within a game-theoretic signaling model. It is shown that a company when being vertically integrated with a supplier may well decide to buy certain components from this supplier even at a lower quality than that offered by external sources. When the...

The last decade has seen the burgeoning of several hundred local community currency institutions in cities across the world. Although residents of these communities claim that local currency promotes local development, how if at all it does so has hitherto been unexplored. This paper argues that...

It can be advantageous for an office motivated party A to spend effort to make it public that a group of voters will lose from party A's policy proposal. Such effort is called inverse campaigning. The inverse campaigning equilibria are described for the case where the two parties can...

This paper develops a multi-period model, in which workers are matched with jobs according to imperfect educational signals and in which their subsequent productivities depend on both their inherent ability and on the quality of the job match. It outlines a sequential process, in which underpaid...

This paper investigates whether education is used as a signaling device for worker productivity in developing countries. To do such we employ a simple test of employer learning on Ghana manufacturing data. We find no evidence of educational signaling for individuals who were hired through direct...

This paper develops a model in which workers to a certain extent enjoy working. We examine the implications of workers' intrinsic motivation for optimal monetary incentive schemes. We show that motivated workers work harder and, for a given level of effort, are willing to work for a lower wage....

This paper presents a test of the educational signaling hypothesis. If employers use education as a signal in the hiring process, they will rely more on education when less is otherwise known about applicants. We find that employers are more likely to lower educational standards when an...

In the context of common agency adverse-selection games we illustrate that the revelation principle cannot be applied to study equilibria of the multi-principal games. We then demonstrate that an extension of the taxation principle - what we term the delegation principle - can be used to...

In public procurement a temporal separation of award and actual contracting can frequently be observed. In this paper we give an explanation for this institutional setting. For incomplete procurement contracts we show that such a separation may increase efficiency. We show that efficiency can be...
