From Iran to Russia to Hong Kong: Geopolitical Risks Are Weighing on the German Economy

Over the past years, there has been an increase in global geopolitical risk, the most recent example being the intensifying conflict between the USA and Iran. Such geopolitical risks also affect the German economy. A geopolitical shock, defined as an unexpected increase in risk, has a significantly negative effect on the development of the German economy, and stock prices fall. By comparison, German ...

Emergency Aid for Self-Employed in the COVID-19 Pandemic: A Flash in the Pan?

Governments in many countries introduced support programs to support the self-employed, including the German federal government, which approved a €50bn emergency aid program at the end of March 2020 offering one-off lump-sum payments of up to €15,000 to those facing substantial revenue ...

Industrial Demand Response: How Network Tariffs and Regulation (Do Not) Impact Flexibility Provision in Electricity Markets and Reserves

Incentives for industrial loads to provide demand response on day-ahead and reserve markets are affected both by network tariffs, as well as regulations on the provision of flexibility in different markets. This paper uses a numerical model of the chlor-alkali process with a storable intermediate good to investigate how these factors affect the provision of demand response in these markets. We also ...

Learning from Data and Network Effects: The Example of Internet Search

The rise of dominant firms in data driven industries is often credited to their alleged data advantage. Empirical evidence lending support to this conjecture is surprisingly scarce. In this paper we document that data as an input into machine learning tasks display features that support the claim of data being a source of market power. We study how data on keywords improve the search result quality ...

The Impact of Carbon Disclosure Mandates on Emissions and Financial Operating Performance

We examine whether a disclosure mandate for greenhouse gas emissions creates stakeholder pressure for firms to subsequently reduce their emissions. For UK-incorporated listed firms such a mandate was adopted in 2013. Using a difference-in-differences design, we find that firms affected by the mandate reduced their emissions – depending on the specification – by an incremental 14-18% relative to a control ...
