We provide the second mover in a trust game and a moonlighting game with an excuse for not reciprocating. While this type of manipulation has been shown to strongly reduce giving in the dictator game, we find that the availability of the excuse has no effect on the incidence of reciprocal...

The paper presents a simple model to study the effects of rumours on markets. Agents in our economy communicate with their local neighbours which gives rise to the possible spread of a rumour. As the rumour affects beliefs of the agents the evolution of the rumour has a direct impact on market...

We show that earnings manipulation destroys incentives within the corporate hierarchy. In the model, top management has incentives to over-report earnings. An insider, for instance, a division manager may gain evidence about over-reporting. We show that the division manager is more likely to...

We study how transition has affected human resource policies of a Russian heavy industry firm. Our data set contains personnel files of 1538 white-collar workers over 17 years: from 1984 to 2000. We find career paths before the first year of Gaidar's reforms, 1992, when Russian transition to a...

We develop a theory of firm scope based on the benefits and costs of resource allocation within firms. Integrating two firms into one makes it possible to allocate by authority scarce resources that are costly to trade. But to do so efficiently, top management must rely on information that is...

We show that the availability of finance affects firms not only through financial markets, but also through the labor market. In our model, talented workers care for realizing their ideas because this can increase their lifetime income, but they also wish to be insured against income risk. Large...

In many organizations, decisions are taken by unanimity giving each member veto power. We analyze a model of an organization in which members with heterogenous productivity privately contribute to a common good. Under unanimity, the least efficient member imposes her preferred effort choice on...

Previous research has documented strong peer effects in risk taking, but little is known about how such social influences affect market outcomes. The consequences of social interactions are hard to isolate in financial data, and theoretically it is not clear whether peer effects should increase...

The introduction of sanctions provides incentives for more pro-social behavior, but may also be a signal that non-cooperation is prevalent. In an experimental minimum-effort coordination game we investigate the effects of the information contained in the choice to sanction. We compare the effect...
