Competition in agricultural markets: an experimental approach

This paper develops an experimental approach to measure competition among intermediaries in agricultural markets, based on the random allocation of subsidies to traders. We show that, in individual-level randomizations with competitive spillovers, treatment-control differences in prices can inform an intuitive test of the degree of differentiation among firms. In the context of the…

Mapping the interconnectedness between EU banks and shadow banking entities

This paper provides a unique snapshot of the exposures of EU banks to shadow banking entities within the global financial system. Drawing on a rich and novel dataset, the paper documents the cross-sector and cross-border linkages and considers which are the most relevant for systemic risk monitoring. From a macroprudential perspective, the identification of potential feedback and…

A Climate stress-test of the financial system

The urgency of estimating the impact of climate risks on the financial system is increasingly recognized among scholars and practitioners. By adopting a network approach to financial dependencies, we look at how climate policy risk might propagate through the financial system. We develop a network-based climate stress-test methodology and apply it to large Euro Area banks in a ‘green…

How Media Coverage of Corporate Social Irresponsibility Increases Financial Risk Media Coverage of Corporate Social Irresponsibility

This article explores the relationship between corporate social irresponsibility (CSI) and financial risk. We posit that media coverage of CSI generates risk by providing conditions that increase the potential for stakeholder sanctions. Through analyzing an international panel of 539 firms during 2008–2013, we find that firms receiving higher CSI coverage face higher financial risk.…

Sind wir so reich, weil die andern so arm sind?

Wir haben nur so viel, weil die anderen so wenig haben. Wären wir grosszügiger, ginge es allen besser. So denken die meisten. Sie irren sich.

Monetáris politika és a bankok hitelkínálata

Növeli-e az alacsony kamatláb a banki hitelkínálatot? Tanulmányunkban egy magyar, vállalati szintű hiteladatbázis panelstruktúrában történő elemzésével keressük a választ a kérdésre. Kashyap–Stein [2000] identifikációs módszerét vállalati és idő fix hatásokkal kiegészítve teszteljük a feltételezést, hogy a kamatok csökkenése különbözőképpen befolyásolja-e az alacsony és a magas…

Was die Universität Berkeley lehrt: Europa verdammt die öffentlichen Universitäten zumeist in die Regionalliga

Die vom US-Bundesstaat Kalifornien betriebene Spitzenschule macht vor, wie sich akademische Exzellenz mit vergleichsweise geringen Mitteln erreichen lässt – doch es gibt Grenzen der Effizienz.

Immigration and voting for the far right

Does the presence of immigrants in one's neighborhood affect voting for far right-wing parties? We study the case of the Freedom Party of Austria (FPÖ) that, under the leadership of Jörg Haider, increased its vote share from less than 5% in the early 1980s to 27% by the end of the 1990s and continued to attract more than 20% of voters in the 2013 national election. We find that…

Optimal estimation of a large-dimensional covariance matrix under Stein’s loss

This paper introduces a new method for deriving covariance matrix estimators that are decision-theoretically optimal within a class of nonlinear shrinkage estimators. The key is to employ large-dimensional asymptotics: the matrix dimension and the sample size go to infinity together, with their ratio converging to a finite, nonzero limit. As the main focus, we apply this method to…

Resurrecting weighted least squares

This paper shows how asymptotically valid inference in regression models based on the weighted least squares (WLS) estimator can be obtained even when the model for reweighting the data is misspecified. Like the ordinary least squares estimator, the WLS estimator can be accompanied by heteroskedasticity-consistent (HC) standard errors without knowledge of the functional form of…

Do professional norms in the banking industry favor risk-taking?

In recent years, the banking industry has witnessed several cases of excessive risk-taking that frequently have been attributed to problematic professional norms. We conduct experiments with employees from several banks in which we manipulate the saliency of their professional identity and subsequently measure their risk aversion in a real stakes investment task. If bank employees…

The lottery contest is a best-response potential game

It is shown that the n-player lottery contest admits a best-response potential (Voorneveld, 2000, Economics Letters). This is true also when the contest technology reflects the possibility of a draw. The result implies, in particular, the existence of a non-trivial two-player zero-sum game that is best-response equivalent to a game with identical payoff functions.

Revenue ranking of optimally biased contests: the case of two players

It is shown that the equilibrium in the asymmetric Tullock contest is unique for parameter values r ≤ 2. This allows proving a revenue ranking result saying that a revenue-maximizing designer capable of biasing the contest always prefers a contest technology with higher accuracy.

Smoking behaviour in Germany: evidence from the SOEP

As in most OECD countries, smoking prevalence and cigarette consumption have been decreasing in Germany since the early 2000s. This paper analyses whether smoking prevalence and cigarette consumption, as well as their development over time, differ between socio-economic subgroups. Identifying these differences provides insights into the effect of policy interventions on German…

Accounting for the new gains from trade liberalization

We measure the "new" gains from trade reaped by Canada as a result of the Canada-US Free Trade Agreement (CUSFTA). We think of the "new" gains from trade of a country as all welfare effects pertaining to changes in the set of firms serving that country as emphasized in the so-called "new" trade literature. To this end, we first develop an exact…

The role of gender in employment polarization

We document that U.S. employment polarization in the 1980-2008 period is largely generated by women. Female employment shares increase both at the bottom and at the top of the skill distribution, generating the typical U-shape polarization graph, while male employment shares decrease in a more similar fashion along the whole skill distribution. We show that a canonical model of skill…

Dividends and leverage: How to optimally exploit a non-renewable investment

In this paper we model the situation where a non-renewable investment is given, for instance a resource reservoir, and show how to optimally trade-off between dividends and leverage, in order to maximize a performance indicator for shareholders, up to the bankruptcy time. We then study the way market risk (the volatility of the market price of the resource) impacts the optimal…
