The limits to moral erosion in markets: social norms and the replacement excuse
This paper studies the impact of a key feature of competitive markets on moral behavior: the possibility that a competitor will step in and conclude the deal if a conscientious market actor forgoes a profitable business opportunity for ethical reasons. We study experimentally whether people employ the argument "if I don’t do it, someone else will" to justify taking a…

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.

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…

Career dynamics and gender gaps among employees in the microfinance sector
While microfinance institutions (MFIs) are increasingly important as employers in the developing world, there is little micro-level evidence on gender differences among MFI employees and MFIs' relation to economic development. We use a unique panel dataset of employees from Latin America's largest MFI to show that gender gaps favouring men for promotion exist primarily in…

We build a large dynamic factor models for a quarterly data set of 30 macroeconomic and financial indicators. Results of forecasting suggest that conditional FAVAR models which incorporate more economic information outperform the…

Lucas Marc Fuhrer: Liquidity in the Repo Market
This paper examines liquidity in the Swiss franc repurchase (repo) market and assesses its determinants using a proprietary dataset ranging from 2006 to 2016. I find that repo market liquidity has a distinct intraday pattern, with low liquidity in early and late trading hours. Moreover, repo market liquidity is negatively affected by stress in the global financial system and the end…

Text-as-data analysis of preferential trade agreements: mapping the PTA landscape
Preferential trade agreements (PTAs) form an intricate web that connects countries across the globe. In this article, we introduce a PTA text corpus and research tools for its finegrained, automated analysis. Recent computational advances allow for efficient and effective content analysis by treating text as data. We digitize PTA texts and use textual similarity tools to assess PTA…

Abandon ship?: party brands and politicians’ responses to a political scandal
In this article, we study politicians’ – rather than voters’ – responses to the main political scandal in Italian recent history (Tangentopoli), and overcome endogeneity concerns by analysing the local implications of this national corruption scandal. We find that local politicians withdraw support for incumbents in parties hit by Tangentopoli – inducing increased political…
