We extend Lazear’s theory of skills variety and entrepreneurship in three directions. First, we provide a theoretical framework linking new business creation with an entrepreneur’s skill variety. Second, in this model we allow for both generalists and specialists to possess skill variety....

Using a country-industry panel dataset (EUKLEMS) we uncover a robust empirical regularity, namely that high-risk innovative sectors are relatively smaller in countries with strict employment protection legislation (EPL). To understand the mechanism, we develop a two-sector matching model where...

Market-based instruments are believed to create more efficient incentives for firmsto adopt new technologies than command-and-control policies. We compare the effects of a directtechnology regulation and of an adoption subsidy under asymmetric information about the costsof technological advances...

We present a continuous-time generalization of the seminal R&D model of d’Aspremont and Jacquemin (American Economic Review, Vol. 78, No. 5) to examine the trade-off between the benefits of allowing firms to cooperate in R&D and the corresponding increased potential for product market...

A consistent mapping of all complex ramifications (including direct and indirect effects) of variousgreenhouse policies in an open institutional economy requires the use of a general equilibriumframework. From the existing set of available equilibrium models we have selected the...

We present a theoretical framework which allows for the comparison of the effectiveness of tax measures, loans and funding, in supporting industry-oriented research. We estimate for each of the instruments the exact contribution required by a firm to decide on investing in R&D, given the costs...

This paper proposes that risk aversion encourages individuals to invest in balancedskill profiles, making them more likely to become entrepreneurs. By not havingtaken this possible linkage into account, previous research has underestimated the impactsboth of risk aversion and balanced skills on...

Theory predicts that entrepreneurs have distinct attitudes towards risk and uncertainty, but empirical evidence is mixed. To better understand the unique behavioral characteristics of entrepreneurs and the causes of these mixed results, we perform a large ‘lab-in-the-field’ experiment...

There is no robust empirical support for the effect of financial incentives on the decision to work in selfemploymentrather than as a wage earner. In the literature, this is seen as a puzzle. We offer a focus on theopportunity cost, i.e. the wages given up as an employee. Information on income...
