Evidence from Sibling Correlations

We assess the broad importance of family and community background for entrepreneurship outcomes. We go beyond traditional, intergenerational associations by estimating sibling correlations in unincorporated and incorporated entrepreneurship using register data from Sweden. Sibling correlations range from 20% to 50%. They are consistently higher for more committed and incorporated entrepreneurship than for less committed or unincorporated entrepreneurship; they are also higher for brothers than sisters. We then assess what factors drive these correlations: parental entrepreneurship, neighborhoods, shared genes and financial resources help explain these high correlations, whereas immigration status, family structure and sibling peer effects have a limited contribution. The higher correlation for incorporated versus unincorporated entrepreneurship is explained mainly by the type of parental entrepreneurial engagement and financial resources, while the gap between brother and sister correlations in unincorporated entrepreneurship is largely driven by the geographic concentration of male dominated industries

Same, but different? Birth order, family size, and sibling sex composition effects in entrepreneurship

Family background matters for entrepreneurship. The focus on factors making siblings similar rather than different, however, may understate the total importance of families for occupational choice by hiding important sources of within-family heterogeneity. I assess the differential effects of birth order, family size, and sibling sex composition on unincorporated and incorporated entrepreneurship in a set of causal exercises using Swedish register data. These factors appear to have a negligible impact. First, while later born men are more likely to become unincorporated entrepreneurs, this effect is largely explained by their lower education and poorer labor market prospects, pointing towards the subsistence nature of this type of entrepreneurship. Second, I find limited evidence of causal family size effects in linear and non-linear instrumental variable approaches, using instruments based on multiple births and sibling gender. Third, while I find no pure sibling sex composition effect, there is a small negative effect of having a brother on the father-daughter association in unincorporated entrepreneurship. Fourth, neither source of within-family heterogeneity exhibits a clear relationship with incorporated entrepreneurship, although children with more than four siblings are less likely to become incorporated business owners. Finally, accounting for within-family differences increases previously estimated sibling correlations by little. The results are consistent with the absence of adult sibling peer effects in entrepreneurship and confirm the role of families in generating sibling similarities, rather than differences in occupational choice. The importance of family background for entrepreneurship is therefore only marginally understated

Continuing patent applications at the USPTO

Despite their growing importance for firm innovation strategy and frequent appearance in U.S. patent policy debates, how continuing patent applications are used remains unclear. Turn-of-the-century reforms strongly limited opportunities to extend patent term and surprise competitors, but continuing applications have steadily risen since. We argue that they retain a subtle use, as applicants can file continuations to keep prosecution open and change patent scope after locking in gains with the initial patent. We document a sharp drop in parent abandonment and rise in continuations per original patent after the reforms. Continuing applications are more privately valuable than original patents, are filed in more uncertain contexts, for higher value technologies, by more strategic applicants, and react strongly to the notice of allowance. The evidence supports a current strategic use of continuing applications to craft claims over time

On the origins of entrepreneurship: evidence from sibling correlations

Despite the consensus that entrepreneurship runs in the family, we lack evidence regarding the total importance of family and community background, as well as the relative importance of different background influences that affect entrepreneurship. We draw on human capital formation theories to argue that families and communities provide a salient context for the development of individual entrepreneurial skills and preferences, beyond the existing focus on parental entrepreneurship. We posit that early influences are more important than later influences and propose a hierarchy of family influences, whereby genes have the largest explanatory power, followed by parental entrepreneurship, neighborhoods, and parental resources, and finally by parental immigration, family structure, and sibling peers. Finally, we argue that the higher human and financial capital intensity of incorporated relative to unincorporated entrepreneurship predictably alters the hierarchy of family influences, as does gender. Sibling correlations estimated on Swedish register data confirm our hypotheses.Lindquist gratefully acknowledges funding from the Swedish Research Council (Vetenskapsrådet 2017-01941)
