Disadvantage and discrimination in self-employment: caste gaps in earnings in Indian small businesses

Using the 2004-05 India Human Development Survey data, we estimate and decompose the earnings of household businesses owned by historically marginalized social groups known as Scheduled Castes and Tribes (SCSTs), and non-SCSTs across the earnings distribution. We find clear differences in characteristics between the two types of businesses with the former faring significantly worse. The mean decomposition reveals that as much as 55 per cent of the caste earnings gap could be attributed to the unexplained component. Quantile regressions suggest that gaps are higher at lower deciles, providing some evidence of a sticky floor. Finally, quantile decompositions reveal that the unexplained component is greater at the lower and middle deciles than higher, suggesting that SCST-owned businesses at the lower and middle end of the conditional earnings distribution face greater discrimination

Creative Destruction and Productive Preemption

We develop a theory of commercialization mode (entry or sale) of entrepreneurial inventions into oligopoly, and show that an invention of higher quality is more likely to be sold (or licensed) to an incumbent due to strategic product market effects on the sales price. Moreover, preemptive acquisitions by incumbents are shown to stimulate the process of creative destruction by increasing the entrepreneurial effort allocated to high-quality invention projects. Using detailed data on patents granted to small firms and individuals, we find evidence that high-quality inventions are often sold, and that they are sold under bidding competition

Self-employment amongst migrant groups: New evidence for England and Wales

Self-employment constitutes a vital part of the economy since entrepreneurs can provide employment not only for themselves but also for others. The link between self-employment and immigration is, however, complex, especially given the changing nature of self-employment. We investigate the evolving relationship between self-employment and immigration using recently released microdata from the 2011 Census for England and Wales. Our findings indicate large variations, with high self-employment rates observed for some groups with a long established history of migration to the UK (especially men born in Pakistan) and also for some groups who have arrived more recently (such as from the EU’s new member states). We further explore the differences, analyse variations by gender and identify key determining factors. In addition to certain socio-economic characteristics, it is found that migration-related influences, such as English language proficiency and period of arrival in the UK, play an important role for some groups

Are women graduates jacquelines-of-all-trades? Challenging Lazear’s view on entrepreneurship

This study challenges the basic reasoning behind Lazear’s theory on entrepreneurship (2005). Based on the key motive of maximizing one’s lifetime income, Lazear posits that individuals with a balanced set of skills should have a higher probability of being self-employed. His ‘‘Jack-of-all-trades’’ hypothesis presumes that entrepreneurs need sufficient knowledge in a variety of areas to succeed, while paid employees benefit from being specialists in a certain area demanded by the labor market. Because most women-led businesses are neither based on the motive of making money nor are they growth oriented, we argue that maximizing their lifetime income is not the main motivation of many women to start a business. However, we argue that Lazear’s theory can be extended to motivations that are mostly stated for women entrepreneurs as well. We apply it to a specific representative sample of 1384 women graduates in Germany and test our hypothesis with logit regression. A dichotomized measure indicating whether a women graduate was self-employed (n = 706) or not (n = 678) served as the dependent variable. Our results widely confirm Lazear’s assumption for women graduates who run relatively small businesses in terms of sales and employment: professional training, balanced industry experience, and balanced entrepreneurship-based self-efficacy increase the probability of being self-employed. Solo self-employed tend to have balanced industry experience more often than those being in a team or having employees. Lazear’s theory has male as the norm, and as such, does not readily apply to the case of women—but could and should be extended to women’s specifics

Chest wall mechanics during artificial ventilation

Chest wall mechanics were studied in six healthy volunteers before and during anesthesia prior to surgery. The intratracheal, esophageal, and intragastric pressures were measured concurrently. Gas flow was measured by pneumotachography and gas volume was obtained from it by electrical integration. Rib cage and abdomen movements were registered with magnetometers, these being calibrated by “isovolume” maneuvers. During spontaneous breathing in the conscious state, rib cage volume displacement corresponded to 40% of the tidal volume. During anesthesia and artificial ventilation, this rose to 72% of the tidal volume. The relative contributions of rib cage and abdomen displacements were not influenced by a change in tidal volume. Compliance was higher with a larger tidal volume, a finding which could be due to a curved pressure-volume relationship of the overall chest wall. </jats:p
