What Happened to the East German Housing Market? – A Historical Perspective on the Role of Public Funding –
Claus Michelsen, Dominik Weiß
IWH Discussion Papers,
No. 20,
2009
Abstract
The paper analyses the development of the East German housing market after the reunification of the former German Democratic Republic and the Federal Republic of Germany in 1990. We analyse the dynamics of the East German housing market within the framework of the well-known stock-flow model, proposed by DiPasquale and Wheaton. We show that the today observable disequilibrium to a large extend is caused by post-unification housing policy and its strong fiscal incentives to invest into the housing stock. Moreover, in line with the stylized empirical facts, we show that ‘hidden reserves’ of the housing market were reactivated since the economy of East Germany became market organized. Since initial undersupply was overcome faster than politicians expected, the implemented fiscal stimuli were too strong. In contrast to the widespread opinion that outward migration caused the observable vacancies, this paper shows that not weakness of demand but supply side policies caused the observable disequilibrium.

Germany’s Production of Export Goods: Human Capital Content Slightly Exceeds that of Imports
Hans-Ulrich Brautzsch, Udo Ludwig
Wirtschaft im Wandel,
No. 11,
2009
Abstract
Getrieben von der wachsenden Weltnachfrage sowie der Internationalisierung der nationalen Produktionsprozesse und begünstigt durch die Verbesserung der preislichen Wettbewerbsfähigkeit hat die deutsche Wirtschaft im Jahrzehnt vor der derzeitigen Weltfinanzkrise die Exportaktivitäten drastisch ausgeweitet. Im gleichen Zeitraum hat sich im Zuge der Tertiärisierung der Wirtschaft die Ausstattung der Produzenten mit Humankapital erhöht. Vor diesem Hintergrund geht die Studie dem qualitativen Wandel des Faktors Arbeit, gemessen an der formalen Qualifikation der Beschäftigten, bei der Entstehung der Exportgüter nach und vergleicht ihn mit dem Geschehen auf der Importseite. Die mit dem Input-Output-Modell und einer eigens dafür generierten Datenbasis erstmalig für das vereinigte Deutschland erzielten empirischen Ergebnisse weisen zwar auf einen in den deutschen Exporten verkörperten Vorteil hin, der jedoch gegenüber den Importen qualifikatorisch nur relativ gering ist. Unter Einschluss des seit Mitte der 90er Jahre anhaltenden Exportüberschusses ist dieser Vorteil jedoch, absolut betrachtet, recht groß. Das spricht für die Realisierung eines Humankapitalvorteils Deutschlands im Exportgeschäft.

Monopolistic Competition and Costs in the Health Care Sector
Ingmar Kumpmann
IWH Discussion Papers,
No. 17,
2009
Abstract
Competition among health insurers is widely considered to be a means of enhancing efficiency and containing costs in the health care system. In this paper, it is argued that this could be unsuccessful since health care providers hold a strong position on the market for health care services. Physicians exert a type of monopolistic power which can be described by Chamberlin’s model of monopolistic competition. If many health insurers compete with one another, they cannot counterbalance the strong bargaining position of the physicians. Thus, health care expenditure is higher, financing either extra profits for physicians or a higher number of them. In addition, health insurers do not have an incentive to contract selectively with health care providers as long as there are no price differences between physicians. A monopolistic health insurer is able to counterbalance the strong position of physicians and to achieve lower costs.

The Gender Pay Gap under Duopsony: Joan Robinson meets Harold Hotelling
Boris Hirsch
Scottish Journal of Political Economy,
No. 5,
2009
Abstract
This paper presents an alternative explanation of the gender pay gap resting on a simple Hotelling-style duopsony model of the labour market. Since there are only two employers, equally productive women and men have to commute and face travel cost to do so. We assume that some women have higher travel cost, e.g., due to more domestic responsibilities. Employers exploit that women on average are less inclined to commute and offer lower wages to all women. Since women's firm-level labour supply is for this reason less wage-elastic, this model is in line with Robinson's explanation of wage discrimination.

Out-migration and Regional Convergence
Alexander Kubis, Lutz Schneider
Wirtschaft im Wandel,
20 Jahre Deutsche Einheit - Teil 1 -
2009
Abstract
Seit 1989 haben netto über 1,8 Millionen Menschen Ostdeutschland den Rücken gekehrt. In diesem Kontext stellt sich die Frage, welcher Zusammenhang zwischen der Binnenmigration – ökonomisch betrachtet der Humankapitalmobilität – und dem regionalen Wachstum besteht. Aus theoretischer Sicht sprechen Gründe sowohl für als auch gegen eine konvergenzfördernde Wirkung von Migration. Insbesondere bei starker Positivselektion der Migranten sollten die Wanderungsbewegungen eher gegen eine Angleichung der Wirtschaftskraft von Regionen wirken.
Im vorliegenden Beitrag wird die Frage, wie Migration und Konvergenz, verstanden als Angleichung der Arbeitsproduktivität, zusammenhängen, auf regionaler Ebene für Deutschland im Zeitraum von 1995 bis 2006 empirisch analysiert. Der methodische Ansatz folgt dem Konzept der Beta-
Konvergenz, geschätzt wird ein Querschnittsmodell auf Basis von Kreisdaten, die auf dieser Ebene vorliegende räumliche Korrelation wird im Modell berücksichtigt.
Im Ergebnis zeigt sich zunächst ein signifikanter Konvergenzprozess auf regionaler Ebene; die ostdeutschen Regionen holen dabei besonders schnell auf. Hinsichtlich der Wirkung von Migration auf regionale Konvergenz finden sich gegenläufige Tendenzen. Die Abwanderung aus armen Regionen wird zwar einerseits begleitet von einem hohen Produktivitätswachstum, die komplementäre Zuwanderung in reiche Regionen geht dort andererseits ebenso mit höherem Wachstum einher. Insofern ist der Konvergenzeffekt der Migration unbestimmt, allerdings sprechen die Ergebnisse für einen wanderungsbedingten Effizienzgewinn auf volkswirtschaftlicher Ebene, wenn die Migration von schwächeren in stärkere Regionen fließt.

Inflation Expectations: Does the Market Beat Professional Forecasts?
Makram El-Shagi
IWH Discussion Papers,
No. 16,
2009
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.

A Simple Macro Model of Original Sin based on Optimal Price Setting under Incomplete Information
Axel Lindner
International Economics and Economic Policy,
2009
Abstract
This paper analyses the consequences of “original sin“ (the fact that the currency of an emerging market economy usually cannot be used to borrow abroad) for macroeconomic stability. The approach is based on third-generation models of currency crises, but differs from alternative versions by explicitly modeling the price setting behavior of firms if prices are sticky and there is incomplete information about the future exchange rate. It is shown that a small depreciation is beneficial, but a large one is detrimental.

Smuggling Illegal versus Legal Goods across the U.S.-Mexico Border: A Structural Equations Model Approach
A. Buehn, Stefan Eichler
Southern Economic Journal,
No. 2,
2009
Abstract
We study the smuggling of illegal and legal goods across the U.S.-Mexico border from 1975 to 2004. Using a Multiple Indicators Multiple Causes (MIMIC) model we test the microeconomic determinants of both smuggling types and reveal their trends. We find that illegal goods smuggling decreased from $116 billion in 1984 to $27 billion in 2004 as a result of improved labor market conditions in Mexico and intensified U.S. border enforcement. Smuggling legal goods is motivated by tax and tariff evasion. While export misinvoicing fluctuated at low levels, import misinvoicing switched from underinvoicing to overinvoicing after Mexico's accession to the GATT and the North American Free Trade Agreement (NAFTA) induced lower tariffs.

Financial constraints and the margins of FDI
Claudia M. Buch
Bundesbank Discussion Paper 29/2009,
2009
Abstract
Recent literature on multinational firms has stressed the importance of low productivity as a barrier to the cross-border expansion of firms. But firms may also need external finance to shoulder the costs of entering foreign markets. We develop a model of multinational firms facing real and financial barriers to foreign direct investment (FDI), and we analyze their impact on the FDI decision (the extensive margin) and foreign affiliate sales (the intensive margin). We provide empirical evidence based on a detailed dataset of German multinationals which contains information on parent-level and affiliate-level financial constraints as well as about the location the foreign affiliates. We find that financial factors constrain firms’ foreign investment decisions, an effect felt in particular by large firms. Financial constraints at the parent level matter for the extensive, but less
so for the intensive margin. For the intensive margin, financial constraints at the affiliate level are relatively more important.
