Some information on the session logistics:
If not stated otherwise, the discussant is the following speaker, with the first speaker being the discussant of the last paper. The last speaker of each session is the session chair. (Exception: invited sessions)
Presenters should speak for no more than 20 minutes, and discussants should limit their remarks to no more than 5 minutes. The remaining time should be reserved for audience questions and the presenter’s responses. We suggest following these guidelines also in the (less common) 3-paper sessions in a 2-hour slot, to allow participants to move between sessions. Discussants are encouraged to avoid summarizing the paper. By focusing on a few questions and comments, the discussants can help start a broader discussion with the audience.

The Price of Regulatory Risk in Housing Markets: Evidence from Berlin 1: University of Regensburg, Germany; 2: ifo Institute, Germany We study how regulatory risk affects housing markets in the aftermath of rent control. In Berlin, a stringent rent cap introduced in 2020 was repealed in 2021, but continued political debate over expropriation and further intervention kept housing policy uncertain. Using micro-level listing data and a difference-in-differences-design comparing Berlin to other major German cities, we show that Berlin's price-rent ratio remained 10–15 percent below its pre-intervention trend three years after repeal. To interpret this persistence, we develop a model in which institutional investors face greater exposure to future regulation, predicting lower asset prices, reduced institutional ownership, and partial crowding-in by private investors. Consistent with these predictions, housing policy uncertainty rose sharply after repeal, and large housing companies reduced their Berlin portfolios, accepted lower sale prices, and sharply cut construction. We conclude that credible threats of future intervention can depress housing valuations and reshape market structure even absent binding regulation.
