Human Capital Mobility and Convergence. A Spatial Dynamic Panel Model of the German Regions
Alexander Kubis, Lutz Schneider
Abstract
Since the fall of the iron curtain in 1989, the migration deficit of the Eastern part of Germany has accumulated to 1.8 million people, which is over 10 percent of its ini-tial population. Depending on their human capital endowment, these migrants might either – in the case of low-skilled migration – accelerate or – in high-skilled case– impede convergence. Due to the availability of detailed data on regional human capital, migration and productivity growth, we are able to test how geographic mobil-ity affects convergence via the human capital selectivity of migration. With regard to the endogeneity of the migration flows and human capital, we apply a dynamic panel data model within the framework of β-convergence and account for spatial depend-ence. The regressions indicate a positive, robust, but modest effect of a migration surplus on regional productivity growth. After controlling for human capital, the effect of migration decreases; this decrease indicates that skill selectivity is one way that migration impacts growth.

Equity Home Bias and Corporate Disclosure
Stefan Eichler
Journal of International Money and Finance,
No. 5,
2012
Abstract
I show that more comprehensive corporate disclosure reduces investors’ uncertainty about domestic companies’ payoffs at no cost, thereby decreasing investors’ equity home bias toward a country. Since investors should base their investment decisions on valid and easily interpretable company information only, more comprehensive disclosure will reduce the home bias only if domestic securities law is sufficiently stratified and domestic companies use international accounting standards. Using panel data for 38 countries from 2003 to 2008 I find that more comprehensive disclosure reduces investors’ home bias, though significantly only for countries that sufficiently enforce their securities law and implement international accounting standards.

The Productivity Effect of Temporary Agency Work: Evidence from German Panel Data
Boris Hirsch, Steffen Müller
Economic Journal,
No. 562,
2012
Abstract
This study investigates the effect of temporary agency work on the user firm’s productivity. We hypothesise that using temporary agency work to enhance numerical flexibility and to screen job candidates may increase productivity, whereas temporary workers’ lower firm-specific human capital and spillover effects on the user’s permanent employees may adversely affect productivity. Other than the sparse existing literature on this issue, we exploit a large panel data set and control for time-invariant and time-varying unobserved heterogeneity by using the system GMM estimator. We find a robust hump-shaped effect of the extent of temporary agency work on the user firm’s productivity.

Technological Intensity of Government Demand and Innovation
Viktor Slavtchev, Simon Wiederhold
Abstract
Governments purchase everything from airplanes to zucchini. This paper investigates whether the technological intensity of government demand affects corporate R&D activities. In a quality-ladder model of endogenous growth, we show that an increase in the share of government purchases in high-tech industries increases the rewards for innovation, and stimulates private-sector R&D at the aggregate level. We test this prediction using administrative data on federal procurement performed in US states. Both panel fixed effects and instrumental variable estimations provide results in line with the model. Our findings bring public procurement within the realm of the innovation policy debate.

What Drives Banking Sector Fragility in the Eurozone? Evidence from Stock Market Data
Stefan Eichler, Karol Sobanski
Journal of Common Market Studies,
No. 4,
2012
Abstract
This article explores the determinants of banking sector fragility in the eurozone. For this purpose, a stock-market-based banking sector fragility indicator is calculated for eight member countries from 1999 to 2009 using the Merton model (1974). Using a panel framework, it is found that the macroeconomic environment, the structure of the banking sector and the intensity of banking regulation all have an effect on banking sector fragility in the eurozone.

The Distorting Impact of Capital Controls
Makram El-Shagi
German Economic Review,
No. 1,
2012
Abstract
This paper uses panel data to show that capital controls have a significant impact on international interest rate differentials. Various types of controls can be distinguished within the data. The analysis shows that the aforementioned effects of capital controls on interest rates are especially strong in the case of capital import controls on portfolio capital; the implementation of these controls has been suggested in the wake of the Asian Crisis to prevent further crises. The results presented herein contradict the hypothesis that capital controls can achieve a restructuring of the maturity of capital inflows without a distortion in international capital allocation.

IWH-Indikatoren zur Kapitalmarktregulierung: Hinweise auf eine Renaissance der Kapitalverkehrskontrollen
Makram El-Shagi
Wirtschaft im Wandel,
No. 6,
2011
Abstract
Mittels der hier erstmals vorgestellten IWH-Indikatoren zur Beschreibung der Regulierungsintensität internationaler Kapitalmärkte ist es möglich, Kapitalverkehrskontrollen künftig mit ökonometrischen Verfahren zu evaluieren. Der Datensatz deckt über 150 Länder und einen Zeitraum von bisher 13 Jahren (1997 bis 2009) ab. Er unterscheidet Kapitalverkehrskontrollen nicht nur nach ihrer Intensität, sondern auch nach der Richtung (Zufluss oder Abfluss) der regulierten Kapitalströme. So kann den unterschiedlichen Folgen von Kapitalmarktpolitik Rechnung getragen werden, je nachdem, ob sie durch Zuflusskontrollen dem Aufbau riskanter Außenpositionen entgegenwirken möchte, oder ob sie – wesentlich weiter verbreitet – auf eine Erhöhung des heimischen
Kapitalangebots abzielt. Die explizite Berücksichtigung von diskretionären Entscheidungsspielräumen gestattet es darüber hinaus, auch die institutionelle Ausgestaltung von Kapitalverkehrskontrollen in die empirische Analyse
einzubeziehen. Erste Auswertungen der Indikatoren zeigen in der Folge der Finanz- und Wirtschaftskrise eine weltweite Renaissance der Regulierung grenzüberschreitender Kapitalströme. Der Anteil regulierter Teilmärkte ist von 2007 bis 2009 global um ca. zehn Prozentpunkte angestiegen. Kapitalimporte und -exporte sind dabei in ähnlicher Form betroffen. Der Anstieg der Kontrollintensität geht nicht auf massive Eingriffe einzelner Staaten zurück, sondern ist
über alle betrachteten Ländergruppen hinweg zu beobachten. Teilweise, wie z. B. in den Transformationsökonomien des früheren Warschauer Paktes, wurden viele Jahre der Liberalisierungsanstrengungen in kurzer Zeit kompensiert. Diese Entwicklung ist insofern bedenklich, als dass sich theoretische Überlegungen bezüglich Kapitalverkehrskontrollen stark widersprechen und auch keine empirische Evidenz vorliegt, die eine solche Politik rechtfertigt.

Inflation Expectations: Does the Market Beat Professional Forecasts?
Makram El-Shagi
North American Journal of Economics and Finance,
No. 3,
2011
Abstract
The present paper compares expected inflation to (econometric) inflation forecasts based on a number of forecasting techniques from the literature using a panel of ten industrialized countries during the period of 1988 to 2007. To capture expected inflation, we develop a recursive filtering algorithm which extracts unexpected inflation from real interest rate data, even in the presence of diverse risks and a potential Mundell-Tobin-effect.
The extracted unexpected inflation is compared to the forecasting errors of ten
econometric forecasts. Beside the standard AR(p) and ARMA(1,1) models, which
are known to perform best on average, we also employ several Phillips curve based approaches, VAR, dynamic factor models and two simple model avering approaches.

The Impact of Fixed Exchange Rates on Fiscal Discipline
Makram El-Shagi
Scottish Journal of Political Economy,
No. 5,
2011
Abstract
In this paper, it is shown that, contrary to standard arguments, fiscal discipline is not substantially enhanced by a fixed exchange rate regime. This study is based on data from 116 countries collected from 1975 to 2004 and uses various estimation techniques for dynamic panel data, in particular a GMM estimation in the tradition Arellano and Bover (1995) and Blundell and Bond (1998). Contrary to previous papers on this topic, the present paper takes into account that the consequences of a new exchange rate regime do not necessarily fully manifest immediately.
