We study the impact of research collaborations in coauthorship networks on research output and how optimal funding can maximize it. Through the links in the collaboration network, researchers create spillovers not only to their direct coauthors but also to researchers indirectly linked to them....

We investigate empirically how sellers react to changes in the population of their consumers, identifying the effects of demand composition and demand size with limited information on costs. We show how pharmacists in Italy selectively increase the price of some products when they observe in...

A structural model of entry and fiscal policy is presented. It shows that taxation of variable production costs can increase product prices, lower competition, and reduce the availability of new products in small markets. The model's test is based on a unique nationwide fiscal experiment. We...

Recent theoretical research has identified many ways how contracts can be used as rent seeking devices vis-à-vis third parties, but there is no empirical evidence on this issue so far. To test some basic qualitative properties of this literature, we develop a theoretical and empirical framework...

Can enrolment incentives reduce the incidence of cream-skimming in the delivery of public sector services (e.g. education, health, job training)? In the context of a large government job training program, we investigate whether the use of enrolment incentives that set different 'shadow prices'...

In this paper we consider the interaction between local workers and migrants in the production process of a firm. Both local workers and migrants can invest effort in assimilation activities in order to increase the assimilation of the migrants into the firm and thereby increase their...

We develop a theory of the market for individual reputation, an indicator of regard by one’s peers and others. The central questions are: 1) Does the quantity of exposures raise reputation independent of their quality? and 2) Assuming that overall quality matters for reputation, does the...

The paper argues that networked firms are likely to have an advantage in securing external finance in countries with weak legal and judicial institutions since it helps financial institutions to minimize the underlying agency costs of lending. An analysis of recent BEEPS data from fifteen...

We explore network effects on generosity for different network dimensions. To this end we elicit multiple network dimensions (friendship, social support, economic exchange, etc.) in a rural village in the Southern hemisphere and measure generosity with a sequence of dictator games conducted in...
