This paper argues that drugs are expensive not because of a lack of competition among research-based pharmaceutical companies, but because of a lack of competition in the drug approval process. Lack of competition in the drug approval process has led to exceedingly high drug development costs....

Small business activity and female entrepreneurship have become increasingly important features of the UK economy since the start of the Great Recession. In this paper, we re-examine the impact of liquidity constraints on new business formation in an instrumental variables framework, using a...

This paper offers the first instrumental variables estimates of the wage returns to volunteer experience. The returns are substantial and differ considerably by gender. The results imply that the unequal valuation of volunteer experience by gender is more important in explaining the gender...

This paper estimates the economic and non-economic returns to volunteering for prime-aged women. Estimates of a DCDP model indicate that an extra year of volunteer experience increases wage offers by 8.5% in future part-time work and by 2.6% in future full-time work. On average, working for free...

Working as a volunteer is a widespread phenomenon that has both individual and societal benefits. In this paper, we identify the wage returns to working for free by exploiting exogenous variation in rainfall across local area districts in England, Scotland and Wales. Instrumental variables...

In this paper we examine the underlying sources of economic concentration in Israel, which is unusually high for a developed and innovative economy. After a brief review of Israel's economic history since the start of the British Mandate, we describe the level of economic concentration,...

Re-licensing requirements for professionals that move across borders are widespread. In this paper, we measure the returns to an occupational license using novel data on Soviet trained physicians that immigrated to Israel. An immigrant re-training assignment rule used by the Israel Ministry of...

Two key issues in the literature on female labor supply are (i) whether persistence in employment status is due to unobserved heterogeneity or state dependence, and (ii) whether fertility is exogenous to labor supply. Until recently, the consensus was that unobserved heterogeneity is very...

In this paper, we formulate a dynamic utility maximization model of female labor force participation and fertility choices and estimate approximate decision rules using data on married women in Italy, Spain and France. The pattern of estimated state dependence effects across countries is...
