CRC TR 224 EPoS Bonn-Mannheim

"On the Trends of Technology, Family Formation, and Women’s Time Allocation" is now available: crctr224.de/research/discu…

Why has fertility declined worldwide? Technological change plays an important role. In a GE model with endogenous fertility, marriage, education & women’s time use, we show skill and gender-biased tech explain 30% of Japan’s fertility decline since 1970.

"Staying Together Forever? Life-Cycle Effects of Overoptimistic Couples" is now available: crctr224.de/research/discu…

Divorce happens in 35–40% of marriages, yet couples expect only ~15%. This overoptimism drives more specialization, less saving, and worse post-divorce outcomes—especially for lower-wage spouses.

"Work from Home, Work for Less? How Workplace Flexibility Affects Mothers’ Careers" is now available: crctr224.de/research/discu…

Is WfH a steppingstone or stumbling block for women’s careers? A calibrated GE model shows expansion raises women’s earnings growth (+7.2pp), narrows the gender gap (−7.4%), and boosts welfare (+11.1%), but entails short-run losses.

"Neutral Optimum in Private-Values Settings" is now available: crctr224.de/research/discu…

We establish a connection between two basic solution approaches to the informed-principal problem that have remained separate since the start of the literature.

"Advertiser Competition and Gatekeeping in Ad Funded Media" is now available: crctr224.de/research/discu…

“Advertiser Competition and Gatekeeping in Ad-Funded Media”: how does the launch of a gatekeeper affects foreclosure incentives of advertisers? Who wins and who loses?

"The Labor Market Impact of the Energy Crisis: Evidence from Germany" is now available: crctr224.de/research/discu…

Evidence from German administrative data shows that the 2022 energy price shock mainly affected wages rather than employment in manufacturing.

"Basic Needs Satisfaction as a Fundamental Distributive Principle: Evidence from the Lab and the Field" is now available: crctr224.de/research/discu…

New evidence that concern for basic needs satisfaction (BNS) is a distinct distributional motive. Across 5 dictator-game experiments in Germany & Georgia (N=446), many give up income and efficiency to meet others’ basic needs—robust across contexts.

"A Temporary VAT Cut as Unconventional Fiscal Policy" is now available: crctr224.de/research/discu…

Exploiting Germany’s temporary 3pp VAT cut (H2 2020), we combine survey + scanner data with a HANK model. High perceived pass-through → more durable (and some semi-durable) spending. Model: aggregate consumption +4.4% on impact.
