Die Bauwirtschaft in Deutschland hat der Krise auch im zweiten Corona-Jahr getrotzt, obwohl die Branche nicht ganz ohne Blessuren durch die Pandemie kommt. Liefereng-pässe, Materialmangel ...
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 ...
This paper examines how wealth and income inequality dynamics are related to fluctuations in the functional income distribution over the business cycle. In a panel estimation for OECD countries between 1970 and 2016, although inequality is, on average countercyclical and significantly associated with the capital share, one-third of the countries display a pro- or noncyclical relationship. To analyze ...

In this paper, we disentangle two mechanisms by performing a lab experiment designed to study the effects of social image concerns and peer information on consumption choices financed through debt taking. We find that ...

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 ...
Studie vergleicht drei Szenarien zur Schaffung einer fossilfreien Energieversorgung – Kosten für direkte Elektrifizierung der Wirtschaft sind niedriger als umfangreicher Einsatz von Wasserstoff oder synthetischen Gasen – Sämtliche Szenarien erfordern einen beschleunigten Ausbau erneuerbarer Energien – Transformation erfordert klare Rahmenbedingungen für Investitionen ...
