A series of experiments in Albania and the Netherlands give us the opportunity to compare behavioral patterns related to tax evasion. Subjects have to decide between a random 'registered' income, the realization of which will be known to the experimenter for sure, and a random 'unregistered'...

We develop a model of strategic networks that captures two distinctive features of interfirm collaboration: bilateral agreements and nonexclusive relationships. Our analysis highlights the relationship between market competition, firms' incentives to invest in R&D, and the architecture of...

This paper is concerned with a policy oriented macroeconomic experiment involving an 'international' economy with a relatively small 'home' country and a large 'foreign' country. It compares the economic performance of two alternative tax systems as a means to finance unemployment benefits: a...

Embedding the efficient bargaining model into the R. Hall (1988) approach for estimating price-cost margins shows that both imperfections in the product and labor markets generate a wedge between factor elasticities in the production function and their corresponding shares in revenue. This...

In this paper we investigate experimentally the functioning of a wage tax financed unemployment benefit system on the development of the budget deficit, unemployment, and some other indicators of economic performance in an international economy. We find support for the hypothesis that...

We study a two-stage R&D project with an abandonment option. Two types of uncertainty influence the decision to start R&D. Demand uncertainty is modelled as a lottery between a proportional increase and decrease in demand. Technical uncertainty is modelled as a lottery between a decrease and...

A physician performs two tasks: making diagnoses and determining treatments. To reduce medical error, residents are supposed to consult their supervisors when they face uncommon circumstances. However, recent research shows that residents are reluctant to do so. This paper presents a model that...
