Reducing Energy System Model Distortions from Unintended Storage Cycling through Variable Costs

Energy system models are used for policy decisions and technology designs. If not carefully used, models give implausible outputs and mislead decision-making. One implausible effect is “unintended storage cycling”, which is observable as simultaneous storage charging and discharging. Methods to remove such misleading effects exist, but are computationally inefficient and sometimes ineffective. Through ...

The Multifaceted Impact of US Trade Policy on Financial Markets

We study the multifaceted effects of trade policy shocks on financial markets using a structural vector autoregression identified via event day heteroskedasticity. We find that restrictive US trade policy shocks affect US and international stock prices heterogeneously, but generally negatively. They increase market uncertainty, lower US interest rates, and lead to an appreciation of the US dollar. ...

Minimum Wage in Germany: Countering the Wage and Employment Gap between Migrants and Natives?

This paper investigates the effects of the introduction of a statutory minimum wage in Germany on the wages and employment of migrants. Migrants are an overrepresented group in the low-wage sector and can be expected to particularly benefit from a minimum wage. We combine a “differential trend adjusted difference-in-differences estimator” (DTADD) and descriptive evidence to evaluate the impact of the ...

Causal Misperceptions of the Part-Time Pay Gap

This paper studies if workers infer from correlation about causal effects in the context of the part-time wage penalty. Differences in hourly pay between full-time and part-time workers are strongly driven by worker selection and systematic sorting. Ignoring these selection effects can lead to biased expectations about the consequences of working part-time on wages (’selection neglect bias’). Based ...

Research and Development in German Industry: High Intensity, Low Growth

Research and development (R&D) expenditure in Germany decreased by 5.3 percent overall in 2020 compared to 2019. While the OECD countries actually slightly increased their R&D expenditure on average for the first time in a crisis-ridden year, it declined more sharply in Germany compared to the financial crisis of 2009; German industry, and here the automotive sector, suffered particularly. The decline ...

Rent Control, Market Segmentation, and Misallocation: Causal Evidence from a Large-Scale Policy Intervention

This paper studies market segmentation that arises from the introduction of rent control. When a part of the market remains unregulated, theory predicts an increase of free-market rents due to the misallocation of households to dwellings. To document this mechanism empirically, we study a large-scale policy intervention in the German housing market. We isolate the misallocation mechanism by exploiting ...

Construction Boom Coming to an End; Change in Policy Strategy Needed

Following the construction boom of recent years in Germany, inflation and supply bottlenecks hit the industry hard in 2022. While nominal construction volume increased by nearly 14 percent, it decreased by two percent when adjusted for inflation. Residential construction, which is urgently needed, was particularly affected. In 2023 and 2024, it is expected that investors will show restraint and that ...
