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...

Physician effects in antibiotic prescribing: Evidence from physician exits

This is an online seminar using Webex. You will receive the login data with the invitation to the talk. Abstract:   Antibiotic resistance is a severe problem within our current health systems. One of the main strategies to combat the rise of antibiotic resistance is to improve individual physicians' antibiotic prescribing practices. However, this strategy requires that differences in...

Determinants and effects of mergers and acquisitions: Evidence from drug projects in the diabetes market

Charlotte will summarize the methodology of textmining for information retrieval, different techniques, advantages and disadvantages. Primarily, she will be discussing the textmining procedure she undertook to develop and verify a database about the merger level characteristics and Commission...

Bayesian Inference for Structural Vector Autoregressions Identified by Markov-Switching Heteroskedasticity

In this study, Bayesian inference is developed for structural vector autoregressive models in which the structural parameters are identified via Markov-switching heteroskedasticity. In such a model, restrictions that are just-identifying in the homoskedastic case, become over-identifying and can be tested. A set of parametric restrictions is derived under which the structural matrix is globally or ...

Constructing Joint Confidence Bands for Impulse Response Functions of VAR Models: A Review

Methods for constructing joint confidence bands for impulse response functions which are commonly used in vector autoregressive analysis are reviewed. While considering separate intervals for each horizon individually still seems to be the most common approach, a substantial number of methods have been proposed for making joint inferences about the complete impulse response paths up to a given horizon. ...

Garzweiler II: Prüfung der energiewirtschaftlichen Notwendigkeit des Tagebaus: Im Auftrag von Greenpeace e.V.

The Macroeconomic Effects of a European Deposit (Re-) Insurance Scheme

Recent proposals for a still missing European deposit insurance scheme (EDIS) argue in favor of a reinsurance framework. In this paper, we use a regime-switching open-economy DSGE model with bank default to assess the relative efficiency of such a scheme. We find that reinsurance by EDIS is more effective in stabilizing real activity, credit, and welfare than a national fiscal backstop. We demonstrate ...

Der schädliche Hype um die Staatsverschuldung

Die Corona-Krise schürt die tief sitzenden Urängste vieler Deutscher vor einer Explosion der Staatsverschuldung und einer Hyperinflation. Nicht wenige warnen in Angesicht der riesigen Wirtschaftshilfen der Bundesregierung vor Schulden, die uns ruinieren könnten. Dies sollte jedoch unsere geringste Sorge sein. Auch wenn es ...

Masterstudium ja oder nein? Gezielte Online-Informationen beeinflussen weitere Studienpläne

Studie auf Basis des Berliner-Studienberechtigten-Panels (Best Up) – Bachelorstudierende wurden über Nutzen und Finanzierung eines Masterstudiums informiert – Männer schätzen im Anschluss Perspektiven mit Bachelorabschluss allein höher ein als zuvor, kein Effekt bei Frauen – Informationsangebote sollten ausgebaut werden Online-Informationen zum Masterstudium verändern ...
