Abstract
In the wake of the 2008/2009 financial crisis, a number of policy reports (Vickers, Liikanen, Volcker) proposed to separate investment banking from commercial banking to increase financial stability. This paper empirically examines one theoretical justification for these proposals, namely attention distortion under multiple tasks as in Holmstrom and Milgrom (1991). Universal banks can be viewed as combining two different tasks (investment banking and commercial banking) in the same organization. We estimate pay-performance sensitivities for different segments within universal banks and for pure investment and commercial banks. We show that the pay-performance sensitivity is higher in investment banking than in commercial banking, no matter whether it is organized as part of a universal bank or in a separate institution. Next, the paper shows that relative pay-performance sensitivities of investment and commercial banking are negatively related to the quality of the loan portfolio in universal banks. Depending on the specification, we obtain a reduction in problem loans when investment banking is removed from commercial banks of up to 12 percent. We interpret the evidence to imply that the higher pay-performance sensitivity in investment banking directs the attention of managers away from commercial banking within universal banks, consistent with Holmstrom and Milgrom (1991). Separation of investment banking and commercial banking may indeed be associated with a reduction in risk in commercial banking.

Burdett–Mortensen Model of on-the-Job Search with Two Sectors
Florian Hoffmann, Shouyong Shi
Review of Economic Dynamics,
Special Issue in Honor of Dale Mortensen
2016
Abstract
The focus of this paper is on the steady state of a two-sector economy with undirected search where employed and unemployed workers can search for jobs, both within a sector and between the sectors. As in the one-sector model, on-the-job search generates wage dispersion among homogeneous workers. The analysis of the two-sector model uncovers a property called constant tension that is responsible for analytical tractability. We characterize the steady state in all cases with constant tension. When time discounting vanishes, constant tension yields the endogenous separation rate in each sector as a linear function of the present value for a worker. The one-sector economy automatically satisfies constant tension, in which case the linear separation rate implies that equilibrium offers of the worker value are uniformly distributed. Constant tension also has strong predictions for worker transitions and value/wage dispersion, both within a sector and between the two sectors. When constant tension does not hold, we compute the steady state numerically and illustrate its properties.

Abstract
Die starken Migrationsprozesse beeinflussen zunehmend auch den ostdeutschen Arbeitsmarkt. Die Zuwachsraten bei der Zahl der Beschäftigten, den Arbeitslosen sowie den Leistungsbeziehern nach SGB II vor allem aus den mittel- und osteuropäischen Staaten mit Arbeitnehmerfreizügigkeit, den von der europäischen Schulden- und Vertrauenskrise besonders schwer betroffenen Ländern Griechenland, Italien, Portugal und Spanien sowie den Asylherkunftsländern sind gegenwärtig sehr hoch und liegen in der gleichen Größenordnung wie in Westdeutschland. Die Anteile von Migranten an der Bevölkerung und an relevanten Arbeitsmarktgrößen sind allerdings in Ostdeutschland erheblich niedriger als in Westdeutschland.

Wirtschaft im Wandel,
Nr. 6,
2015
Abstract
Der seit dem vierten Quartal 2014 zu beobachtende Beschäftigungsrückgang hat sich fortgesetzt. Im zweiten Quartal 2015 nahm die Zahl der Erwerbstätigen saisonbereinigt mit 0,2% sogar noch etwas stärker ab als in den beiden Quartalen zuvor. Dabei lag im ersten Halbjahr 2015 das Bruttoinlandsprodukt um 1,1% über dem Vorjahresstand. In Westdeutschland, wo das Bruttoinlandsprodukt um 1,5% zunahm, legte die Beschäftigung weiter zu.

Censored Fractional Response Model: Estimating Heterogeneous Relative Risk Aversion of European Households
Qizhou Xiong
IWH Discussion Papers,
Nr. 11,
2015
Abstract
This paper estimates relative risk aversion using the observed shares of risky assets and characteristics of households from the Household Finance and Consumption Survey of the European Central Bank. Given that the risky share is a fractional response variable belonging to [0, 1], this paper proposes a censored fractional response estimation method using extremal quantiles to approximate the censoring thresholds. Considering that participation in risky asset markets is costly, I estimate both the heterogeneous relative risk aversion and participation cost using a working sample that includes both risky asset holders and non-risky asset holders by treating the zero risky share as the result of heterogeneous self-censoring. Estimation results show lower participation costs and higher relative risk aversion than what was previously estimated. The estimated median relative risk aversions of eight European countries range from 4.6 to 13.6. However, the results are sensitive to households’ perception of the risky asset market return and volatility.

Understanding the Great Recession
Mathias Trabandt, Lawrence J. Christiano, Martin S. Eichenbaum
American Economic Journal: Macroeconomics,
Nr. 1,
2015
Abstract
We argue that the vast bulk of movements in aggregate real economic activity during the Great Recession were due to financial frictions. We reach this conclusion by looking through the lens of an estimated New Keynesian model in which firms face moderate degrees of price rigidities, no nominal rigidities in wages, and a binding zero lower bound constraint on the nominal interest rate. Our model does a good job of accounting for the joint behavior of labor and goods markets, as well as inflation, during the Great Recession. According to the model the observed fall in total factor productivity and the rise in the cost of working capital played critical roles in accounting for the small drop in inflation that occurred during the Great Recession.

Arbeitsmarktbilanz Ostdeutschland: Beschäftigungsrückstand gegenüber dem Westen etwas geringer als bisher ausgewiesen
Hans-Ulrich Brautzsch
Wirtschaft im Wandel,
Nr. 6,
2014
Abstract
Für die Bundesländer liegen noch keine amtlichen Angaben zur Zahl der Erwerbstätigen vor, die mit den im Rahmen der Generalrevision 2014 der Volkswirtschaftlichen Gesamtrechnungen neu berechneten Erwerbstätigenzahlen für Deutschland insgesamt kompatibel sind. Die Entwicklung der Erwerbstätigkeit kann deshalb nur auf der Grundlage der revidierten Beschäftigungsstatistik analysiert werden. Die Zahl der Beschäftigten wurde in Ostdeutschland stärker nach oben korrigiert als in den Alten Bundesländern. Damit dürfte die Revision der Erwerbstätigenzahl für Ostdeutschland höher ausfallen als für Westdeutschland. Dies hat auch Auswirkungen auf die Arbeitslosenquote, die nunmehr etwas geringer ausgewiesen werden dürfte als zuvor.
Die günstige Beschäftigungsentwicklung in der ersten Hälfte des Jahres 2014 dürfte dazu führen, dass im Durchschnitt des Jahres 2014 die Zahl der Erwerbstätigen in Ostdeutschland etwas über dem Vorjahreswert liegen wird. Die registrierte Arbeitslosigkeit wird – wie in den Jahren zuvor – vom schrumpfenden Arbeitsangebot beeinflusst. Die Arbeitslosenquote dürfte in diesem Jahr 9,5% betragen, nach 10,1% im Vorjahr.

Spillover Effects among Financial Institutions: A State-dependent Sensitivity Value-at-Risk Approach
Z. Adams, R. Füss, Reint E. Gropp
Journal of Financial and Quantitative Analysis,
Nr. 3,
2014
Abstract
In this paper, we develop a state-dependent sensitivity value-at-risk (SDSVaR) approach that enables us to quantify the direction, size, and duration of risk spillovers among financial institutions as a function of the state of financial markets (tranquil, normal, and volatile). For four sets of major financial institutions (commercial banks, investment banks, hedge funds, and insurance companies) we show that while small during normal times, equivalent shocks lead to considerable spillover effects in volatile market periods. Commercial banks and, especially, hedge funds appear to play a major role in the transmission of shocks to other financial institutions.

Micro-Based Evidence of EU Competitiveness: The CompNet Database
Filippo di Mauro, et al.
ECB Working Paper,
Nr. 1634,
2014
Abstract
Drawing from confidential firm-level balance sheets in 11 European countries, the paper presents a novel sectoral database of comparable productivity indicators built by members of the Competitiveness Research Network (CompNet) using a newly developed research infrastructure. Beyond aggregate information available from industry statistics of Eurostat or EU KLEMS, the paper provides information on the distribution of firms across several dimensions related to competitiveness, e.g. productivity and size. The database comprises so far 11 countries, with information for 58 sectors over the period 1995-2011. The paper documents the development of the new research infrastructure, describes the database, and shows some preliminary results. Among them, it shows that there is large heterogeneity in terms of firm productivity or size within narrowly defined industries in all countries. Productivity, and above all, size distribution are very skewed across countries, with a thick left-tail of low productive firms. Moreover, firms at both ends of the distribution show very different dynamics in terms of productivity and unit labour costs. Within-sector heterogeneity and productivity dispersion are positively correlated to aggregate productivity given the possibility of reallocating resources from less to more productive firms. To this extent, we show how allocative efficiency varies across countries, and more interestingly, over different periods of time. Finally, we apply the new database to illustrate the importance of productivity dispersion to explain aggregate trade results.
