Forward to the Past: Short-Term Effects of the Rent Freeze in Berlin

In 2020, Berlin introduced a rigorous rent-control policy responding to soaring rents by setting a cap on rental prices: the Mietendeckel (rent freeze). The policy was revoked one year later by the German Constitutional Court. Although successful in reducing rents during its duration, the consequences for Berlin’s rental market and adjacent municipalities are not clear. In this paper we evaluate the ...

R&D Spillovers through RJV Cooperation

We investigate how R&D spillovers propagate across firms linked through Research Joint Ventures (RJVs). Building on the framework developed by Bloom et al. (2013) which considers the opposing effects of knowledge spillovers and product market rivalry, we extend the model to account for RJV cooperation. Since the firm’s decision to join a RJV is endogenous, we build a model of RJV participation. The ...

A Behavioral Heterogeneous Agent New Keynesian Model

We propose a behavioral heterogeneous agent New Keynesian model in which monetary policy is amplified through indirect general equilibrium effects, fiscal multipliers can be larger than one and which delivers empirically-realistic intertemporal marginal propensities to consume. Simultaneously, the model resolves the forward guidance puzzle, remains stable at the effective lower bound and determinate ...

When surfing the web, consumers leave digital traces that can be used to build user profiles and infer preferences.

Common Ownership Patterns in the European Banking Sector: The Impact of the Financial Crisis

We provide a description of ownership patterns in the top 25 European banks for the period 2003–2015, where we especially focus on the global financial crisis. Investment managers, such as Blackrock, are dominant in terms of number of blockholdings in different banks, maintaining fairly stable “common ownership” networks throughout our sample. However, the financial crisis led to capital injections ...

Antitrust Policy and Innovation

Innovation has recently come to the attention of Antitrust Authorities, even though the effect of mergers on innovation is still hotly debated. I study how the activity of Antitrust Authorities impacts future innovation of merging firms. Exploiting a change in notification rules I build an event study comparing mergers notified to the authorities with non-notified ones. I develop a new methodology...

Venture Capital in Diabetes: A Yes to Big Hits, a No to Competition

Venture capital (VC) is often seen as an instrumental tool that allows many start-ups to pursue innovation with the potential to shake-up current markets and/or to replace incumbents. Using a highly granular, project-level dataset from preclinical diabetes R&D, this paper shows that VCs actively steer the direction of R&D and streamline activities of research focused firms (pipeline firms)...
