What is the social value of innovations in Schumpeterian growth models? This issue is tackled by introducing the concept of Lindahl equilibrium in a standard endogenous growth model with vertical innovations which is extended by explicitly considering knowledge diffusion on a Salop (1979)...

This paper examines how product market competition affects firms’ timing of adopting a new technology as well as whether the market provides sufficient adoption incentives. It shows that adoption dates differ not only among symmetric firms but also among markets with Cournot and Bertrand...

It has long been argued that the implementation of market-based environmental policy instruments such as environmentally-related taxes and tradable permits is likely to lead to greater technological innovation than more direct forms of regulation such as technology-based standards. One of the...

Given that young children are under the control of their parents, if the government has an interest in either the welfare or the productivity of the former, it has no option but to act through the latter. Parents are, in the ordinary sense of the word, the government’s agents. They are agents...

This paper investigates the question whether long-term human capital outcomes are affected by the duration of maternity leave, i.e. by the time mothers spend at home with their newborn before returning to work. Employing RD and difference-in-difference approaches, this paper exploits an...

This paper applies the theory of relational contracts to a model in which a couple decides whether to marry or cohabit, how many children to have and subsequently whether to stay together or separate. We make precise the idea that cooperation in a household can be supported by self interest....

We examine the effect of pregnancy and parenthood on the research productivity of academic economists. Combining the survey responses of nearly 10,000 economists with their publication records as documented in their RePEc accounts, we do not find that motherhood is associated with low research...

Despite the relevance of cognitive and non-cognitive skills for professional success, their formation is not yet fully understood. This study fills part of this gap by analyzing the effect of sports club participation, one of the most popular extra-curricular activities, on children’s skill...

In this paper we develop an overlapping generations model in which child care matters for human capital accumulation. We investigate whether an increase in labor supply brought about by a reduction in taxes is always associated with a reduction in parental time devoted to children, which...

This paper investigates how mothers’ decision to stay at home with young children affects their subsequent work careers. Identification is based on the introduction of the Cash-for-Care program in Norway in 1998, which increased mothers’ incentives to withdraw from the labor market when...
