This paper examines the impacts of new policies aimed at reducing the cost of renting by regulating the actions of intermediaries in the rental market. We highlight how information frictions between buyers and intermediaries can give rise to rents in the thick two-sided market. The distribution of these rents between intermediaries and sellers, as well as the impact of price regulation, depends on...
In this case study, we examine a novel aspect of data collected in a typical probability and a typical nonprobability panel: mobile app data. The data were collected in Great Britain in 2018, using the Innovation Panel of the UK Household Longitudinal Study and the Lightspeed online access panel. Respondents in each panel were invited to participate in a month-long study, reporting all their daily ...
Business cycle models often abstract from persistent household heterogeneity, despite its potentially significant implications for macroeconomic fluctuations and policy. We show empirically that the likelihood of being persistently financially constrained decreases with cognitive skills and increases with overconfidence thereon. Guided by this and other micro evidence, we add persistent heterogeneity ...
This paper examines whether biased income expectations due to overconfidence lead to higher levels of debt taking. We show suggestive evidence for a link between overconfidence and borrowing behavior in a representative survey of German households (German Socio-Economic Panel–Innovation Sample [GSOEP-IS]). This motivates a laboratory experiment to study causality behind these effects. In two experiments, ...

Large mergers between manufacturers typically impact competition, thus requiring the approval of Competition Authorities. Divestitures are often a condition of merger approval. This report investigates the effectiveness of implementing ...
