Multivariate Adaptive Regression Spline (MARS) is a simple and powerful non-parametric technique that automatizes the selection of non-linear terms in regression models. Non-linearities and spatial effects are natural characteristics in numerous spatial hedonic pricing models. In this paper, we propose using the MARS data-driven methodology combined with the Instrumental Variables method in order to ...
Following World War I, rent control became a standard policy response to the housing shortage and the resulting rent increases. Typically, economists blame it for creating inefficiencies in the housing market and beyond. We investigate whether rental market regulations (including rent control, protection of tenants from eviction, and housing rationing) had any effects in a middle-income Latin American ...
Cities worldwide have regulated peer-to-peer short-term rental platforms claiming that those platforms remove apartments from the long-term housing market, causing an in- crease in rents. Establishing and quantifying such a causal link is, however, challenging. We investigate two policy changes in Berlin to first assess how effective they were in regulating Airbnb, the largest online peer-to-peer short-term ...
Der technische Fortschritt in den Informationstechnologien eröffnet beispiellose wirtschaftliche Möglichkeiten. Durch eine drastische Reduzierung der Kosten dieser Technologien ist es heute so einfach wie noch nie, Informationen und Wissen zu akquirieren, zu kommunizieren und Produkte und Dienstleistungen zu handeln. Die damit einhergehende Umwälzung der Wirtschaft wirft zahlreiche ökonomische Fragestellungen ...
This study introduces a new international longitudinal database of governmental rental market regulations. The regulations are measured using binary variables based on a thorough analysis of real-time, country-specific legislation. Three major restrictive policies are considered: rent control, protection from restriction, and housing rationing. The database covers 101 countries and states between 1910 ...
This is an online seminar using Webex. You will receive the login data with the invitation to the talk. Abstract: Cities worldwide have regulated the peer-to-peer short-term rental market claiming that those markets remove apartments from the long-term housing market, causing an increase in rents. However, at the time many of these policies were passed, empirical evidence for or...
Unfortunately the event is canceled. As soon as a new date is fixed, it will be announced here on the website. BAMS is a joint seminar by the DIW Berlin, the Hertie School of Governance, the HU Berlin and the WZB.
The (re-)introduction of rent regulation in the form of rent controls, tenant protection or supply rationing is back on the agenda of policymakers in light of rent inflation in many global cities. While rent control as social policy promises short-term relief, economists point to their negative long-run effects on new construction. This paper present long-run data on both rent regulation and housing ...
We consider the problem of regression with selectively observed covariates in a nonparametric framework. Our approach relies on instrumental variables that explain variation in the latent covariates but have no direct effect on selection. The regression function of interest is shown to be a weighted version of observed conditional expectation where the weighting function is a fraction of selection ...
Die digitale Ökonomie hat unzählige Märkte nachhaltig verändert. Insbesondere Online Plattformen bieten eine noch nie dagewesene Auswahl an Produkten, gekoppelt mit innovativer Technologie, die das Zusammenfinden von Angebot und Nachfrage vereinfacht, Vertrauen aufbaut und Suchkosten reduziert. Gleichzeitig hat die neuartige Natur dieser Plattformen dazu geführt, dass sie teilweise mit den etablierten ...
