This paper investigates whether self-employed households use consumer loans – in particular instalment loans and overdrafts – to finance business activities. Controlling for financial and non-financial household variables we show that self-employed households particularly use personal...

Based on a large employer-employee matched data set, the paper investigates the effects of variable enforcement of German dismissal protection legislation on the employment dynamics in small establishments. Specifically, using a difference-in-differences approach, we study the effect of changes...

According to the German disability law, or Schwerbehindertengesetz, either six percent of all jobs in an establishment must be occupied by disabled employees or the firm has to pay a penalty of DM 200 per month for every job under consideration. This note reports results from the first...

We analyze the link between R&D, innovation, and productivity in MSMEs with a special focus on micro firms with fewer than 10 employees; usually constituting the majority of firms in industrialized economies. Using the German KfW SME panel, we examine to what extent micro firms are different...

We revisit the link between poverty, the middle class and institutional outcomes using a newly developed cross-country panel dataset containing detailed information on the distribution of income and expenditures. When the size of the middle class increases (measured as the proportion of people...

This paper presents evidence on the making of the middle class in Africa by exploiting a comparable micro data from the Demographic and Health Surveys (DHS) for thirty-seven countries over two decades consisting of over seven hundred thousand household histories. We constructed a pseudo-panel to...

In many developing countries, the supply of skilled workers is likely to continue to be stronger than demand, and this should drive down the skill premium and reduce inequality. Within the limitations of any exercise based on simulations, this paper finds that the recently observed reduction in...

We investigate whether Chinese household incomes have caught up to those of the middle class in the developed world. Using nationwide survey data for 2002 and 2013, we find considerable catch up. Defining the global middle class as being neither poor nor rich in the developed world, we estimate...

In a polarised and highly unequal country such as South Africa, it is unlikely that a definition of the middle class that is based on an income threshold will adequately capture the political and social meanings of being middle class. We therefore propose a multi-dimensional definition, rooted...

Empirical evidence for the U.S. suggests that illicit consumption of opioids increases in association with socio-economic deprivation of the middle-class. To explore the underlying mechanisms, we set up a task-based labor market model with endogenous mental health status and a health care...
