We present a structural framework for the evaluation of public policies intended to increase job search intensity. Most of the literature defines search intensity as a scalar that influences the arrival rate of job offers; here we treat it as the number of job applications that workers send out....

In this era of globalisation the traditional Ricardian theory of trade in products governed by comparative advantages is replaced by a modern theory of trade in tasks. Tasks are outsourced to those places in the world where the lower production costs outweigh the additional transaction costs...

The number of immigrants across the world has doubled since 1980. The estimates of the impact of immigration on wages and employment in host countries are quantitatively small but vary widely. We use meta-regression analysis to show how the estimates vary with definitions of the labor market,...

This paper conducts the first general equilibrium analysis of the role of entry, exit and profits in industry dynamics. The benefit of our model is twofold. First, to discriminate between entrants’ role of performing the entrepreneurial function of creating disequilibrium and the conventional...

This article examines to what extent recent empirical evidence can collectively and systematically substantiate the claim that entrepreneurship has important economic value. Hence, a systematic review is provided that answers the question: What is the contribution of entrepreneurs to the economy...

The main contribution of entrepreneurship theory to economics is to provide an account of market performance in disequilibrium but little empirical research has examined firm entry and exit in this context. We redress this by modelling the interrelationship between firm entry and exit in...

How do people react to setbacks and successes? I introduce a new measure of challenge-seeking to determine the effect of winning and losing in a competition on the willingness to seek further challenges. Participants in a lab experiment compete in two-person tournaments and are then informed of...
