Using individual level data from Turkstat Household Labor Force Survey for 2005-2009 period and a variety of parametric and semi-parametric techniques, we test two hypothesis regarding formal and informal labor markets: whether there is a wage gap between formal and informal workers and whether...

There is a debate about the labor market concentration being behind the anemic development of US wages over the past decades. The absence of exogenous variations for causal inference complicates this debate. Here, data from other countries can help. I exploit a variation from a quasi-natural...

This paper investigates the behaviour of employers' monopsony power and workers' wages over the business cycle. Using German administrative linked employer--employee data for the years 1985--2010 and an estimation framework based on duration models, we construct a time series of the firm-level...

Using administrative data for West Germany, we investigate whether part of the urban wage premium stems from fierce competition in thick labour markets. We first document fewer search frictions in denser labour markets. We further show that controlling for search frictions lowers the wage...

This paper estimates the employment effects of industry-specific, collectively-bargained minimum wages in Germany for three occupations associated with the construction sector using a difference-in-differences approach. I propose a truly exogenous control group in contrast to the control group...

In this paper, we investigate regional differences in the gender pay gap both theoretically and empirically. Within a spatial oligopsony model, we show that more densely populated labour markets are more competitive and constrain employers' ability to discriminate against women. Utilising a...

It has recently been argued that the informal sector in developing countries shows a dual structure, with part of the informal sector being competitive to the formal sector and part of the informal sector being the result of market segmentation. We formulate an econometric model to test this...

The self-employed constitute a large proportion of the workforce in developing countries and the sector has been found to be growing further. Different accounts exist as to the cause of this development, with pull factors such as high returns to capital and increased wealth contrasted with push...

We use a 100% sample of social security panel micro data for estimating the effects of a minimum wage in the German construction sector. In 1997, a wage floor was introduced at different rates in West and East Germany. For analysing the impact of this natural experiment we conceptually follow a...

This paper investigates immigrants and natives labour supply to the firm within a semi-structural approach based on a dynamic monopsony framework. Applying duration models to a large administrative employer employee data set for Germany, we find that once accounting for unobserved worker...
