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...
