We analyse a model in which families may either be 'traditional' single-earner with caring for the child at home or 'modern' double-earner households using market child care. Family policies may favour either the one or the other group, like market care subsidies vs. cash for care. Policies are...

I investigate causal machine learning (CML) methods to estimate effect heterogeneity by means of conditional average treatment effects (CATEs). In particular, I study whether the estimated effect heterogeneity can provide evidence for the theoretical labour supply predictions of Connecticut's...

The inheritance tax is often seen as an effective tool to reduce wealth inequality, to raise public budgets if needed, and to increase incentives to work by lowering the tax burden on labour, which is especially high in Germany according to the OECD. The purpose of this paper is therefore to...

In its decarbonization efforts, the European Union aims to decrease energy consumption through technological advances. One of the most prominent advances is the increased extension and utilization of digital information and communication technologies. However, there is little understanding of...

This paper aims to measure the impact of broadband speed on economic growth in the OECD countries. The macroeconomic indicators for this study were collected from OECD databases, except for the speed data, which were gathered from Ookla, a company that provides broadband testing and web-based...

This paper analyses the impact of business process outsourcing (BPO) on firm productivity based on a comprehensive German firm-level panel data set covering manufacturing and service industries. The growing importance of service inputs into the production process is undisputed. Firms...

The paper studies the nature of spillover effects in bank lending flows from advanced to the emerging markets and identifies specific channels through which such effects occur. Based on a gravity approach, we examine a panel data set on cross-border bank flows from 17 BIS reporting advanced...

This paper discusses two longstanding questions in growth econometrics which involve multiple hypothesis testing. In cross sectional GDP growth regressions many variables are simultaneously tested for significance. Similarly, when investigating pairwise convergence of output in panel data sets...

This paper employs a wage-setting approach to analyze the labor market effects of immigration into Germany. The wage-setting framework relies on the assumption that wages tend to decline with rising unemployment, albeit imperfectly. This enables us to consider labor market rigidities, which are...

Bt cotton has been cultivated in China for the past 10 years. Limitations of previous studies analyzing the impact of this technology are the short time period considered and lack of panel data. In this paper, we present findings from monitoring 150 Bt cotton farmers in 2002 and 2005....
