Effects of the statutory minimum wage on the wage structure and hours worked

The research project aims at identifying causal effects of the introduction of the minimum wage and its first uprating on both wages and hours worked. Based on the Structure of Earnings Survey (SES) and the Earnings Surveys of the German Federal Statistical Office on the one side and the German Socio-Economic Panel (GSOEP) on the other side, a number of questions will be answered with regard to the development of wages, such as: How has the wage structure changed due to the introduction and uprating of the statutory minimum wage? What impact did the introduction and uprating of the statutory minimum wage have on hourly and monthly wages for different categories of employees? Additionally, minimum wage effects on employees’ non-monetary situation will be examined. This includes aspects such as life satisfaction, motivation or social participation.

Effects of the statutory minimum wage on establishments and firms

The research project aims at identifying causal effects of the minimum wage on the competitiveness of affected establishments and firms as well as the adjustments made by establishments and firms. Based on existing research findings, the long-term effects of the introduction as well as the short-term effects of the first and possibly the second uprating of the minimum wage on establishments and firms will be evaluated. In particular it will be analysed how productivity, profits, the closure and formation of firms, investments and outsourcing were affected by the minimum wage.

Behaviour of firms and employees in the context of the minimum wage

The objective of the research project is the qualitative identification and description of the effects of the minimum wage on affected firms and employees, as well as their reactions. The foci of the research are the actions and responses of firms and employees, their motives and the relevant contextual factors. The research project will look specifically at the effects of the minimum wage introduction in 2015 and its uprating in 2017 on areas like compliance, implementation costs and adjustment channels. The project will be based on a qualitative research design.

Effects of the statutory minimum wage on self-employment

The research project’s goal is to identify causal effects of the statutory minimum wage on freelance work and self-employment (without employees). The question that should be answered is: What impact did the introduction and the increase of the minimum wage have on the extent of freelance work and self-employment. Furthermore, freelance work and self-employment will be described and compared in its characteristics to other enterprises.

Effects of the statutory minimum wage on household income, consumption and saving

Theoretically it is an open question whether, and if so, how the introduction of the minimum wage affects total gross income, consumption and saving of private households in Germany. The project will analyse the minimum wage’s impact on income, consumption and savings behaviour of private households. The analyses will be based on the German Socio-Economic Panel (GSOEP) and the German Einkommens- und Verbraucherstichprobe (sample survey of income and expenditure).

Effects of the statutory minimum wage on the pensions of the statutory pension insurance

The goal of the research project is to clarify the effects of the statutory minimum wage on pensions. Based on a simulation model the effect of the introduction of the minimum wage on central pension values will be calculated. The research program will cover the following two main topics: Firstly, how does the statutory minimum wage affect the adjustment of the current pension value and the different factors in the pension adjustment formula? Secondly, do the effects differ across different socio-demographic groups, forms of employment or regions?

Potential use of administrative statistics for the evaluation of the statutory minimum wage

The aim of the research project is to assess the potential of German administrative firm data for the evaluation of the statutory minimum wage. The relevant data are the "German administrative firm data (AFiD)" and the "Combined firm data for Germany (KombiFiD)". The research project shall clarify the accessibility of the data for periods before and after the introduction of the minimum wage and whether panel data or cross-sectional data are available.

Methods to evaluate the effects of the statutory minimum wage on undeclared work

The research project compares different approaches to evaluate possible minimum wage effects on undeclared work. This includes their suitability for an ex post analysis regarding the introduction and first uprating of the minimum wage as well as their suitability for ex post analyses of future upratings.
