Ein europäisches Roboterrecht – überfällig oder überflüssig?

Das EU-Parlament hat Empfehlungen zu zivilrechtlichen Regelungen im Bereich Robotik ausgesprochen und die EU-Kommission aufgefordert, einen Legislativvorschlag für den Bereich Robotik mit besonderem Blick auf zivilrechtliche Haftungsfragen auszuarbeiten. Zweifelhaft ist, ob eine Europäische Roboter-Richtlinie notwendig und zweckmäßig ist.

The paper contributes to the debate shedding light on the controversial relation between risk-diversification and financial stability. We model a financial network where assets held by borrowers to meet their obligations, include claims against other borrowers and…

Tail Risk in Hedge Funds : A Unique View from Portfolio Heldings

We develop a new tail risk measure for hedge funds to examine the impact of tail risk on fund performance and to identify the sources of tail risk. We find that tail risk affects the cross-sectional variation in fund returns, and investments in both, tail-sensitive stocks as well as options, drive tail risk. Moreover, managerial incentives and discretion as well as exposure to…

Direct Nonlinear Shrinkage Estimation of Large-Dimensional Covariance Matrices

This paper introduces a nonlinear shrinkage estimator of the covariance matrix that does not require recovering the population eigenvalues first. We estimate the sample spectral density and its Hilbert transform directly by smoothing the sample eigenvalues with a variable-bandwidth kernel. Relative to numerically inverting the so-called QuEST function, the main advantages of direct…

Do Local Governments Tax Homeowner Communities Differently?

This paper investigates whether and how strongly the share of homeowners in a community affects residential property taxation by local governments. Different from renters, homeowners bear the full property tax burden irrespective of local market conditions, and the tax is more salient to them. "Homeowner communities" may hence oppose high property taxes in order to protect…

Signaling to experts

We study competitive equilibrium in a signaling economy with heterogeneously informed buyers. In terms of the classic Spence (1973) model of job market signaling, firms have access to direct but imperfect information about worker types, in addition to observing their education. Firms can be ranked according to the quality of their information, i.e. their expertise. In equilibrium,…

Gender bias in teaching evaluations

This paper provides new evidence on gender bias in teaching evaluations. We exploit a quasi-experimental dataset of 19,952 student evaluations of university faculty in a context where students are randomly allocated to female or male instructors. Despite the fact that neither students' grades nor self-study hours are affected by the instructor's gender, we find that women…

Does expanding regional train service reduce air pollution?

We assess how regional rail service affects air pollution in Germany, where rail service is procured in auctions or negotiations. We argue that the procurement mode is plausibly exogenous, and show that auctions deliver stronger rail service growth than negotiations. Instrumenting rail service growth with procurement mode, we find that increasing rail service by 10% reduces carbon…

Students are almost as effective as professors in university teaching

Many universities around the world rely on student instructors—current bachelor’s and master’s degree students—for tutorial teaching, yet we know nothing about their effectiveness. In a setting with random assignment of instructors to students, we show that student instructors are almost as effective as senior instructors at improving their students’ short- and longer-run academic…

Gregor Bäurle, Matthias Gubler and Diego R. Känzig: International inflation spillovers - the role of different shocks

We analyze how the transmission of international inflation spillovers depends on the nature of the underlying shocks that drive inflation abroad. We find evidence for substantial heterogeneity in the magnitude of spillovers to domestic inflation related to the fundamental source of international price fluctuations and the corresponding monetary policy reactions. Indeed, it turns out that…

Alain Galli: Which indicators matter? Analyzing the Swiss business cycle using a large-scale mixed-frequency dynamic factor model

For policy institutions such as central banks, it is important to have a timely and ac-curate measure of past and current economic activity and the business cycle situation. The most prominent example for such a measure is gross domestic product (GDP). However, GDP is only released at a quarterly frequency and with a substantial delay. Furthermore, it captures elements that are not…
