Observations on munition workers, most of them women, are organized to examine the relationship between their output and their working hours. The relationship is nonlinear: below an hours threshold, output is proportional to hours; above a threshold, output rises at a decreasing rate as hours...

Using a large data set for Germany, we show that both the raw and the unexplained gender earnings gap are higher in self-employment than in paid employment. Applying an Oaxaca-Blinder decomposition, more than a quarter of the difference in monthly self-employment earnings can be traced back to...

Utilising a large representative data set for Germany, this study contrasts absenteeism of self-employed individuals and paid employees. We find that absence from work is clearly less prevalent among the self-employed than among paid employees. Only to a small extent, this difference can be...

The objective of this paper is to assess the relationship between the health and the income from work of wage earners and self-employed workers in Cameroon. Health status is measured by a self-assessment of an individual's health; and income is measured by the monthly wage of the wage earners...

Using a large representative German data set and various concepts of self-employment, this paper tests the "jack-of-all-trades" view of entrepreneurship by Lazear (AER 2004). Consistent with its theoretical assumptions we find that self-employed individuals perform more tasks and that their work...

The informal sector plays an important role in the functioning of labor markets in emerging economies. To characterize better this highly heterogeneous sector, we conduct a distributional analysis of the earnings gap between informal and formal employment in Brazil, Mexico and South Africa,...

If certain start-up characteristics will indicate a business success, knowing such characteristics could generate more successful start-ups and more efficient start-up counseling. Our study will contribute to this by quantifying individual success determinants of freelance start-ups. The data...

According to Gibrat’s Law of Proportionate Effect, the growth rate of a given firm is independent of its size at the beginning of the period examined. While earlier studies tended to confirm the Law, more recent research generally rejects it. This paper reconciles these two streams of...

We investigate the returns to capital and capital accumulation using panel data of Peruvian micro enterprises (MEs). Marginal returns to capital are found to be very high at low levels of capital, but rapidly decreasing at higher levels. The dynamic analyses of capital accumulation in MEs...
