How Communication Makes the Difference between a Cartel and Tacit Collusion: A Machine Learning Approach

This paper sheds new light on the role of communication for cartel formation. Using machine learning to evaluate free-form chat communication among firms in a laboratory experiment, we identify typical communication patterns for both explicit cartel formation and indirect attempts to collude tacitly. We document that firms are less likely to communicate explicitly about price fixing and more likely ...

Discriminatory Auction Design for Renewable Energy

Designing auctions that favor low resource quality installations allows countries to geographically diversify their renewable energy production, while lowering payments to low-cost producers. In this paper, we develop a stylized model showing that a discriminatory auction design favoring low-wind-yield locations leads to a tradeoff between production costs and producer rent and that the scheme can ...

Emobpy: A tool for time series generation of battery electric vehicles

emobpy is a Python open-source tool that enables us to generate battery electric vehicle time series. The tool was released in 2020 on Gitlab and PyPI for the first time. A description of the tool was published as an open-access article in Scientific Data. Now we have just passed the 10K downloads!. We want to reach out to everyone who uses emobpy or is...

Stranded Investments in the Coal Export Industry?

The Case of the Australian Galilee Basin Thermal coal exporters face increasing uncertainty about future coal demand and the risk of asset stranding is increasing. Nevertheless, new export-oriented coal mine projects like the Carmichael project in the Australian Galilee Basin are still brought forward. In this seminar, we discuss research results with the COALMOD-World model with Australian...

Empirical Essays on Local Pollution and Environmental Policies

Externe Effekte lokaler Umweltverschmutzung sind ein zentrales Thema der Umweltökonomie. Da die Maßnahmen zur Minderung lokaler Umweltverschmutzung in den letzten Jahren immer strenger wurden, wird dieses Thema in Zukunft an Bedeutung gewinnen. Vor diesem Hintergrund ist es von entscheidender Bedeutung, die Schäden, die Individuen und Unternehmen durch lokale Umweltverschmutzung erfahren, zu quantifizieren ...
