Openness and Income Disparities: Does Trade Explain The 'Mezzogiorno' Effect?
Claudia M. Buch, P. Monti
Review of World Economics,
No. 4,
2010
Abstract
We use Italian regional data to answer the question whether trade affects within-country income differentials. In Italy, the more affluent Northern regions trade more with the rest of the world than the poorer ones in the Southern “Mezzogiorno” regions. Prima facie, there is a positive correlation between external trade and per capita income. Studying this relationship empirically requires taking into account the endogenous component of trade. We argue that panel cointegration models can complement instrumental variables techniques to account for the endogeneity of trade in a panel context. Both methods show a positive link between trade openness and the level of income per capita.

From District Capital to State Capital: What are the Consequences of Rebuilding the East German States for the System of Cities?
Albrecht Kauffmann
Wirtschaft im Wandel,
No. 12,
2009
Abstract
20 years after the German unification, one may ask what consequences for the system of East German cities follow from the changes of the institutional framework. It may be expected that gains or losses of a location in the hierarchy of central places significantly affect the outcome of economic activity as well as the accumulation of – particularly human – capital. The reorganisation of countries on the territory of the former GDR that has elevated five former district capitals to the status of state capitals while the other ones became urban municipalities has created a model case whose implications were investigated by the IWH. The main objective was to identify a pattern of group formation within the former district capitals on the basis of socioeconomic indicators that coincides with the subgroups out of them with and without the status of a capital state. By means of cluster analysis, we have found that already from 1995 to 2000, differences between both groups with regard to income, structure of employment, human capital, and other indicators were significantly. In the period from 2002 to 2007, the spread of income is growing not only between both groups but also within the group of state capitals, dividing their cluster. We can conclude that the allocation of political institutions of higher centrality has influence on local economic development.

The Standing of the East German Cities within the German System of Cities: An Interim Review on the Basis of Economic Indicators 20 Years after the German Unification

Wirtschaft im Wandel,
20 Jahre Deutsche Einheit - Teil 1 -
2009
Abstract
The hopes of the East German citizens coupled with the unification in 1990 were not only directed to their personal fortune, but also concerned the amelioration of the living conditions in their cities. Twenty years after this date, we can strike an interim balance how far these hopes have been become true. For this purpose, the thirteen largest East German cities (without Berlin) are compared to cities of similar size in three West German regions (South, North, Center represented by North Rhine/Westphalia). The indicators chosen rely to the cities’ economic and fiscal conditions. The indicators paint a differentiated picture: The average income per capita in the East German cities is still lower than in the West German cities and unemployment rates are still above the West German level. With respect to future growth potential, the East German cities show a relatively good endowment with qualified human capital, with public universities and research institutions. In contrast to that, the small size of the firms and the small number of firm headquarters are unfavourable for a dynamic growth in the future. Another persistent difference between East and West is the low level of public revenues, which keeps the East German cities dependent on Federal grants. The city officials were successful in cutting payroll costs and reducing the number of civil servants. In spite of the diverse depicted economic problems still to be solved, the East German cities over the years have shown impressive endurance in catching-up.

Energy Efficient Homes in Germany: Lower Energy Requirement in the East and the South – Results of the ista-IWH-Energy-Efficiency-Index 2007
Claus Michelsen
Wirtschaft im Wandel,
No. 9,
2009
Abstract
At the latest since the oil crisis in the beginning of the 1970s, energy efficiency of homes became a widely discussed topic. In the past, it were in first line aspects of the scarcity of fossil energy sources that motivated the debate. Nowadays, climate protection is a main goal of the European energy policy. For this purpose, a new instrument was introduced in 2009. Europe-wide, the “Energy Performance Certificate” for buildings presents detailed information on the required energy for heating, warm water and (indirectly) the resulting costs for tenants. This instrument is designed to provide further information for consumers to influence their behavior in favor of energy efficient buildings.
Until now, there is only little information on spatial aspects of the energy efficiency of housing in Germany. This article presents data on the level of Germany’s NUTS2 regions. In our calculations, we include information on more than 2.6 million flats, interpolating it representatively for the total stock of multifamily buildings and considering the regional climate.
The results of the first ista-IWH-Energy-Efficiency-Index indicate large differences between regions. The required energy for housing is much lower in the eastern and southern parts of Germany, compared to the western or northern parts. Explanations can be seen in a different structure of the housing stock (e.g. age of construction, level of refurbishment). Moreover, first analyses of the market structure indicate that owner occupied flats are more efficient in energy requirement than rental flats. Vacancy rates, the duration of occupation of rented flats and the level of regional income play an additional role for the energy efficiency of the regional housing stock.

Openness and Growth: The Long Shadow of the Berlin Wall
Claudia M. Buch, Farid Toubal
Journal of Macroeconomics,
No. 3,
2009
Abstract
The question whether international openness causes higher domestic growth has been subject to intense discussions in the empirical growth literature. This paper addresses the issue in the context of the fall of the Berlin Wall in 1989. We analyze whether the slow convergence in per capita incomes between East and West Germany and the lower international openness of East Germany are linked. We address the endogeneity of openness by adapting the methodology proposed by Frankel and Romer (1999) to a panel framework. We instrument openness with time-invariant exogenous geographic variables and time-varying exogenous policy variables. We also distinguish the impact of different channels of integration. Our paper has three main findings. First, geographic variables have a significant impact on regional openness. Second, controlling for geography, East German states are less integrated into international markets along all dimensions of integration considered. Third, the degree of openness for trade has a positive impact on regional income per capita.

Low Skill but High Volatility?
Claudia M. Buch
CESifo Working Paper No. 2665,
2009
Abstract
Globalization may impose a double-burden on low-skilled workers. On the one hand, the relative supply of low-skilled labor increases. This suppresses wages of low-skilled workers and/or increases their unemployment rates. On the other hand, low-skilled workers typically face more limited access to financial markets than high-skilled workers. This limits their ability to smooth shocks to income intertemporally and to share risks across borders. Using cross-country, industry-level data for the years 1970 - 2004, we document how the volatility of hours worked and of wages of workers at different skill levels has changed over time. We develop a stylized theoretical model that is consistent with the empirical evidence, and we test the predictions of the model. Our results show that greater financial globalization and development increases the volatility of employment, and this effect is strongest for low-skilled workers. A higher share of low-skilled employment has a dampening impact.

Trade's Impact on the Labor Share: Evidence from German and Italian Regions
Claudia M. Buch
IAW Discussion Paper No. 46,
2008
Abstract
Has the labor share declined? And what is the impact of international trade? These
questions are not only relevant in an international context they also matter for
understanding the regional distribution of incomes in a given country. In this
paper, we study two regions with trade exposures that differ from the rest of the
country, and which display distinct changes in the labor share. East German and
Southern Italian regions have a degree of international openness which is below
the countries’ averages. At the same time, there has been a more pronounced
decline in the labor share in East Germany than in West Germany. In Southern
Italy, the labor share has increased in recent years. We show that increased trade
openness is not the main culprit behind changing labor shares.

The Great Risk Shift? Income Volatility in an International Perspective
Claudia M. Buch
CESifo Working Paper No. 2465,
2008
Abstract
Weakening bargaining power of unions and the increasing integration of the world economy may affect the volatility of capital and labor incomes. This paper documents and explains changes in income volatility. Using a theoretical framework which builds distribution risk into a real business cycle model, hypotheses on the determinants of the relative volatility of capital and labor are derived. The model is tested using industry-level data. The data cover 11 industrialized countries, 22 manufacturing and services industries, and a maximum of 35 years. The paper has four main findings. First, the unconditional volatility of labor and capital incomes has declined, reflecting the decline in macroeconomic volatility. Second, the idiosyncratic component of income volatility has hardly changed over time. Third, crosssectional heterogeneity in the evolution of relative income volatilities is substantial. If anything, the labor incomes of high- and low-skilled workers have become more volatile in relative terms. Fourth, income volatility is related to variables measuring the bargaining power of workers. Trade openness has no significant impact.

Rents and Quality of Life in Eastern Germany
Dominik Weiß
IWH Discussion Papers,
No. 12,
2008
Abstract
The rent levels between East- and Westgermany differ less than one Euro on average. This difference seems very slow regarding the persistant economic disparities and high vacancy rates in East-Germany.
Based on the assumtion, that income and life quality aspects have an impact on the local rent level a set of variables is regressed on the rent of several housing quality segments in a cross-section analysis at the community-level. The regression contains demographic, economic and housing-market-related variables and a dummy variable for east germany. It incorporates hypotheses about a special supplier structure and several market interventions that are related to the transformation process from socialistic into market economic structures after the reunification in the 1990s.
The results show a significant positive coeficiant for the east german dummy in two segments of the housing stock. Further Research about the reasons for the extra charge are important, because theese findings may be responsible for the continous out migration from East Germany.
