This paper focuses on the innovative actions of entrepreneurs, namely their tendency to reveal the intellectual capital that results from their research efforts either in the form of public knowledge (publications) or private knowledge (patents). Using data collected by the National Research...

There is great interest in evaluating the impact of private equity investments on innovation and economic growth. However, there is no direct empirical evidence on the effects of such transactions on the innovation strategies of entrepreneurial firms. We fill this gap by examining a rich...

In this paper we show that the patenting behavior of creative entrepreneurs is correlated with the patenting behavior of their fathers, which we refer to as a source of the entrepreneurs' human capital endowments. Our argument for this relationship follows from established theories of...

We offer empirical information on the correlates of commercialization activity for research projects funded through the U.S. National Institutes of Health's (NIH's) Small Business Innovation Research (SBIR) award program. Based on this analysis we suggest possible recommendations for improving...

This study investigates the economic consequences of parental leave mandates using data for 16 European countries over the 1969 through 1988 period. Since women use virtually all of the family leave in most nations, men constitute a reasonable comparison group and the natural experiment in most...

This paper examines potential tradeoffs between research methods in answering important questions versus providing more cleanly identified estimates on problems that are potentially of lesser interest. The strengths and limitations of experimental and quasi-experimental methods are discussed and...

We explore whether the 2008 economic collapse in Iceland and subsequent economic crisis affected the probability of ischemic heart disease (IHD) events, independent of regular cyclical effects attributed to typical economic conditions. We estimate linear probability models using administrative...

Prekindergarten programs are expanding rapidly, but to date, evidence on their effects is quite limited. Using rich data from Early Childhood Longitudinal Study, we estimate the effects of prekindergarten on children's school readiness. We find that prekindergarten increases reading and...

We study the relationship between international trade, technology, and the probability and consequences of job displacement, using data on displaced workers as well as those at risk of job dislocation for 1984-86 and 1989-91. Workers employed in industries with elevated import shares and high...

This study examines the relationship between economic conditions and health. Fixed-effect models are estimated using state level data for the 1972-1991 time period. Health is proxied by total and age- specific mortality rates, as well as by 10 particular causes of death. Total mortality and nine...
