Data is often at the core of digital products and services, especially when related to online advertising. This has made data protection and privacy a major policy concern. When surfing the web, consumers leave digital traces that can be used to build user profiles and infer preferences. We quantify the extent to which Facebook can track web behavior outside of their own platform. The network of engagement ...

Natural gas prices in Germany saw a strong increase at the end of 2021, subsequently worsening with the start of the war in Ukraine in February 2022, raising concerns about the distributional consequences. Our study shows that low-income households are affected the most by the natural gas price increase. Low-income households pay at the median 11.70 percent of their equivalent income on gas bills, ...

The 2022 natural gas price spikes across Europe raised concerns regarding their distributional consequences. This paper investigates the distributional effect of price increases between and, in particular, within different income groups in Germany, accounting for different determinants of gas expenditures. The study finds that low-income households are affected the most by the gas price increase. Low-income ...

Coal consumption and production have sharply declined in recent years in the U.S., despite political support. Reasons are mostly unfavorable economic conditions for coal, including competition from natural gas and renewables in the power sector, as well as an aging coal-fired power plant fleet. Nevertheless, coal remains a major energy source in the North American energy markets. Supplementing EMF34 ...

The experimental literature on antitrust enforcement provides robust evidence that communication plays an important role for the formation and stability of cartels. We extend these studies through a design that distinguishes between innocuous communication and communication about a cartel, sanctioning only the latter. To this aim, we introduce a participant in the role of the competition authority, ...

As COP26 drew to a close earlier this month, almost 200 nations agreed to “phase down” coal power in the coming years. How this is done, for coal and other fossil fuels, will have implications for individuals and communities that depend on these resources for their livelihoods.
The case study conducted by DIW Berlin focuses on Germany and the efforts it has undertaken to support ...

We consider a Green Public Procurement setting where the procurer provides a bid discount to environment-friendly technologies to foster their use. We assume that, before the auction, firms may switch to green technology via a publicly observable costly investment. We show that investment acts as a signaling device. This mitigates the effect of incomplete information on firms’ costs, thereby triggering ...

State-of-the-art, open access numerical modeling of imperfectly competitive energy markets offers a sound and transparent way to address topical research questions in energy and commodity markets. We use an open access equilibrium model, the Global Gas Model (GGM), and sector-specific, politically motivated scenarios to investigate the prospects for sales of liquefied natural gas (LNG) from the U.S. ...
