Academic faculty governance and recruitment decisions (2011)

Jens Prüfer Uwe Walz

We analyze the implications of the governance structure in academic faculties for their recruitment decisions when competing for new researchers. The value to individual members through social interaction within the faculty depends on the average status of their fellow members. In recruitment decisions, incumbent members trade off the effect of entry on average faculty status against alternative uses of the recruitment budget if no entry takes place. We show that the best candidates join the best faculties but that they receive lower wages than some lesser ranking candidates. We also study the allocation of surplus created by the entry of a new faculty member and show that faculties with symmetric status distributions maximize their joint surplus under majority voting.

Insuring non-verifiable losses (2011)

Neil A. Doherty Christian Laux Alexander Muermann

Insurance contracts are often complex and difficult to verify outside the insurance relation. We show that standard one-period insurance policies with an upper limit and a deductible are the optimal incentive-compatible contracts in a competitive market with repeated interaction. Optimal group insurance policies involve a joint upper limit but individual deductibles and insurance brokers can play a role implementing such contracts for the group of clients. Our model provides new insights and predictions about the determinants of insurance.

New evidence on the effectiveness of 'Quantitative Easing' in Japan (2011)

Konstantinos Voutsinas Richard A. Werner

Central banks have recently introduced new policy initiatives, including a policy called ‘Quantitative Easing’ (QE). Since it has been argued by the Bank of England that “Standard economic models are of limited use in these unusual circumstances, and the empirical evidence is extremely limited” (Bank of England, 2009b), we have taken an entirely empirical approach and have focused on the QE-experience, on which substantial data is available, namely that of Japan (2001-2006). Recent literature on the effectiveness of QE has neglected any reference to final policy goals. In this paper, we adopt the view that ultimately effectiveness will be measured by whether it will be able to “boost spending” (Bank of England, 2009b) and “will ultimately be judged by their impact on the wider macroeconomy” (Bank of England, 2010). In line with a widely held view among leading macroeconomists from various persuasions, while attempting to stay agnostic and open-minded on the distribution of demand changes between real output and inflation, we have thus identified nominal GDP growth as the key final policy goal of monetary policy. The empirical research finds that the policy conducted by the Bank of Japan between 2001 and 2006 makes little empirical difference while an alternative policy targeting credit creation (the original definition of QE) would likely have been more successful.

The lessons from QE and other 'unconventional' monetary policies - evidence from the Bank of England (2011)

Victor Lyonnet Richard A. Werner

This paper investigates the effectiveness of the ‘quantitative easing’ policy, as implemented by the Bank of England in March 2009. Similar policies had been previously implemented in Japan, the U.S. and the Eurozone. The effectiveness is measured by the impact of Bank of England policies (including, but not limited to QE) on nominal GDP growth – the declared goal of the policy, according to the Bank of England. Unlike the majority of the literature on the topic, the general-to-specific econometric modeling methodology (a.k.a. the ‘Hendry’ or ‘LSE’ methodology) is employed for this purpose. The empirical analysis indicates that QE as defined and announced in March 2009 had no apparent effect on the UK economy. Meanwhile, it is found that a policy of ‘quantitative easing’ defined in the original sense of the term (Werner, 1994) is supported by empirical evidence: a stable relationship between a lending aggregate (disaggregated M4 lending, i.e. bank credit for GDP transactions) and nominal GDP is found. The findings imply that BoE policy should more directly target the growth of bank credit for GDP-transactions.

Early life conditions and financial risk–taking in older age (2011)

Dimitris Christelis Loretti I. Dobrescu Alberto Motta

Using life-history survey data from eleven European countries, we investigate whether childhood conditions, such as socioeconomic status, cognitive abilities and health problems influence portfolio choice and risk attitudes later in life. After controlling for the corresponding conditions in adulthood, we find that superior cognitive skills in childhood (especially mathematical abilities) are positively associated with stock and mutual fund ownership. Childhood socioeconomic status, as indicated by the number of rooms and by having at least some books in the house during childhood, is also positively associated with the ownership of stocks, mutual funds and individual retirement accounts, as well as with the willingness to take financial risks. On the other hand, less risky assets like bonds are not affected by early childhood conditions. We find only weak effects of childhood health problems on portfolio choice in adulthood. Finally, favorable childhood conditions affect the transition in and out of risky asset ownership, both by making divesting less likely and by facilitating investing (i.e., transitioning from non-ownership to ownership).

The unintended consequences of the debt ... will increased government expenditure hurt the economy? (2011)

Richard A. Werner

In 2008, governments in many countries embarked on large fiscal expenditure programmes, with the intention to support the economy and prevent a more serious recession. In this study, the overall impact of a substantial increase in fiscal expenditure is considered by providing a novel analysis of the most relevant recent experience in similar circumstances, namely that of Japan in the 1990s. Then a weak economy with risk-averse banks seemed to require some of the largest peacetime fiscal stimulation programmes on record, albeit with disappointing results. The explanations provided by the literature and their unsatisfactory empirical record are reviewed. An alternative explanation, derived from early Keynesian models on the ineffectiveness of fiscal policy is presented in the form of a modified Fisher-equation, which incorporates the recent findings in the credit view literature. The model postulates complete quantity crowding out. It is subjected to empirical tests, which were supportive. Thus evidence is found that fiscal policy, if not supported by suitable monetary policy, is likely to crowd out private sector demand, even in an environment of falling or near-zero interest rates. As a policy conclusion it is pointed out that by changing the funding strategy, complete crowding out can be avoided and a positive net effect produced. The proposed framework creates common ground between proponents of Keynesian views (as held, among others, by Blinder and Solow), monetarist views (as held in particular by Milton Friedman) and those of leading contemporary macroeconomists (such as Mankiw).

Eurobonds zur Bewältigung der europäischen Krise? : Wegweisung zu einer modernen Entwicklungsunion (2011)

Hans-Helmut Kotz Jan Pieter Krahnen Christian Leuz Helmut Siekmann

Die aktuelle Debatte um den Umgang mit der Verschuldung Griechenlands und anderer EWU Staaten berührt die Grundlagen europäischer Wirtschaftspolitik. Die nächsten Schritte sind wohl abzuwägen, um über eine unmittelbare Kriseneindämmung hinaus eine langfristige Stabilisierung der wirtschaftlichen und politischen Strukturen in der Eurozone zu erreichen. Eine funktionsfähige Wirtschafts- und Währungsunion hat ihren Preis. Sie ist aber auch von großem Nutzen, gerade für Deutschland und die wettbewerbsstarken Regionen, die insbesondere vom einheitlichen Binnenmarkt und der monetären Stabilität profitieren. Das rechtfertigt zugleich eine Unterstützung ökonomisch schwächerer Mitglieder der Union durch die stärkeren. Historisch waren Währungsunionen ohne einen derartigen minimalen fiskalischen Ausgleich nicht dauerhaft. Deshalb sind, wenn man die Währungsunion aufrechterhalten will, zwei Extrempositionen - keine Transfers, um keinen Preis ebenso wie deren Gegenteil: jedwedes Defizit wird bedingungslos finanziert - nicht zielführend. Ein kompletter Haftungsausschluss (no bail-out) ist nicht glaubwürdig, solange unabweisbare Schuldenschnitte von insolventen Staaten oder Regionen (wegen Überschuldung) nicht möglich sind, weil sie innerhalb eines stark integrierten Bankenmarktes potentiell unkontrollierbare Rückwirkungen auslösen. Andererseits liefe die unkonditionierte, dauerhafte Finanzierung regionaler Ungleichgewichte auf Transfervolumina hinaus, die eine Überforderung der Transfergeber darstellten. Sie führte vor allem zu einer Perpetuierung der Probleme, weil Anreize zur letztlich unabdingbaren Anpassung fehlten. Damit bleiben zur Schaffung der Voraussetzungen einer funktionsfähigen Währungsunion nur Optionen, die zwischen den Polen liegen.

Capturing the zero: a new class of zero-augmented distributions and multiplicative error processes (2011)

Nikolaus Hautsch Peter Malec Melanie Schienle

We propose a novel approach to model serially dependent positive-valued variables which realize a non-trivial proportion of zero outcomes. This is a typical phenomenon in financial time series observed at high frequencies, such as cumulated trading volumes. We introduce a flexible point-mass mixture distribution and develop a semiparametric specification test explicitly tailored for such distributions. Moreover, we propose a new type of multiplicative error model (MEM) based on a zero-augmented distribution, which incorporates an autoregressive binary choice component and thus captures the (potentially different) dynamics of both zero occurrences and of strictly positive realizations. Applying the proposed model to high-frequency cumulated trading volumes of both liquid and illiquid NYSE stocks, we show that the model captures the dynamic and distributional properties of the data well and is able to correctly predict future distributions.

The merit of high-frequency data in portfolio allocation (2011)

Nikolaus Hautsch Lada M. Kyj Peter Malec

This paper addresses the open debate about the usefulness of high-frequency (HF) data in large-scale portfolio allocation. Daily covariances are estimated based on HF data of the S&P 500 universe employing a blocked realized kernel estimator. We propose forecasting covariance matrices using a multi-scale spectral decomposition where volatilities, correlation eigenvalues and eigenvectors evolve on different frequencies. In an extensive out-of-sample forecasting study, we show that the proposed approach yields less risky and more diversified portfolio allocations as prevailing methods employing daily data. These performance gains hold over longer horizons than previous studies have shown.
