Abstract
Since 1989, the migration deficit of East Germany has accumulated to 1.8 million people. Against this background, the contribution analyses the relationship between regional migration and regional growth. From a theoretical point of view, one might find reasons in favour and in opposition to a convergence supporting function of migration. If migrants are taken from the upper tail of the human capital distribution of a poor region, divergence is the probable outcome. If on the other hand people with low human capital endowment move to richer regions, migration might enhance regional convergence.
The empirical analysis how regional migration and convergence are interrelated is performed on the basis of German districts within a period from 1995 to 2006. The concept of ß-convergence is applied and a cross-section model controlling for spatial correlation between the error terms is estimated.
The results indicate convergence on the regional level; East German regions seem to catch up particularly fast. The effect of migration is twofold. Out-migration from poor region is correlated with strong growth in these regions. However, the corresponding migration towards richer region is accompanied with growth in these regions, too. Therefore, the impact of migration on convergence is uncertain. Nevertheless, the outcome is in favour of an aggregate benefit of migration if people move from poor to rich regions.

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.

Great Moderation at the Firm Level? Unconditional vs. Conditional Output Volatility
Claudia M. Buch, Jörg Döpke, K. Stahn
B.E. Journal of Economic Analysis and Policy,
No. 1,
2009
Abstract
We test whether there has been a “Great Moderation“ of output volatility at the firm level. The multifactor residual model proposed by Pesaran (2006) is used to isolate the idiosyncratic component of firms' sales growth from macroeconomic developments. This methodology is applied to a balanced panel of about 1,200 German firms covering a 35-year period (1971-2005). Our research has three main findings. First, unconditional firm-level volatility and aggregate output volatility have seen similar downward trends. Second, conditional, idiosyncratic firm-level volatility does not exhibit a downward trend. Third, there is a positive link between growth and volatility at the firm level.

Is the European Monetary Union an Endogenous Currency Area? The Example of the Labor Markets
Herbert S. Buscher, Hubert Gabrisch
IWH Discussion Papers,
No. 7,
2009
Abstract
Our study tries to find out whether wage dynamics between Euro member countries became more synchronized through the adoption of the common currency. We calculate bivarate correlation coefficients of wage and wage cost dynamics and run a model of endogenously induced changes of coefficients, which are explained by other variables being also endogenous: trade intensity, sectoral specialization, financial integration. We used a panel data structure to allow for cross-section weights for country-pair observations. We use instrumental variable regressions in order to disentangle exogenous from endogenous influences. We applied these techniques to real and nominal wage dynamics and to dynamics of unit labor costs. We found evidence for persistent asymmetries in nominal wage formation despite a single currency and monetary policy, responsible for diverging unit labor costs and for emerging trade imbalances among the EMU member countries.

Contestability, Technology and Banking

ZEW Discussion Papers, No. 09-007,
No. 7,
2009
Abstract
We estimate the effect of internet penetration on retail bank margins in the euro area. Based on an adapted Baumol [1982] type contestability model, we argue that the internet has reduced sunk costs and therefore increased contestability in retail banking. We test this conjecture by estimating the model using semi-aggregated data for a panel of euro area countries. We utilise time series and cross-sectional variation in internet penetration. We find support for an increase in contestability in deposit markets, and no effect for loan markets. The paper suggests that for time and savings deposits, the presence of brick and mortar bank branches may no longer be of first order importance for the assessment of the competitive structure of the market.

Race to the Market: Can Standards Survive the Acceleration of Innovation and Product Life Cycles?

Abstract
Plagiarism of emerging market countries has for a considerable time been seen as the main challenge to the western approach of codifying and securing intellectual property rights (IPRs). This neglects the fact that historically all countries which tried to converge to the level of successful economies copied technology. The discussion shadows our view that the more imminent question is whether the steady increase in competition intensity which shortens product life cycles and puts pressure on the invention and innovation system, provides enough time to patent and to standardize. As patent activity not only provides incentives for sinking costs into R&D but is also a first step in the dissemination of technologies, and as standards, especially formal standards, generate level playing fields in broad and reliable markets, this may be critical in the long run. Furthermore, the migration of technologies as a result of a steady reorganization of the spatial division of labor may lead to the adverse situation that countries harboring technologies do not have appropriate institutions for knowledge codification.
Exogenous factors that – at least in the short run – cannot be influenced by the standardization bodies are the level of cooperation among interested parties (and mutual trust and institutional linkage), the competitiveness of the technology, the ability to generate externalities by knowledge codification, and the productivity of the technologies. The most important single success factor that standardization bodies can influence is the speed with which a committee proceeds to timely publish formal standards. With reference to a game-theoretical model and based on data for 1997 and 2007 on published formal standards, we show that until now, standardization bodies seem to have successfully coped with the situation.

New Limits of Municipal Economic Activity: Expansion versus Reduction?
Peter Haug
Wirtschaft im Wandel,
No. 12,
2007
Abstract
On October 11th and 12th 2007, the department of urban economics of the Halle Institute for Economic Research organized a conference on local governments’ entrepreneurial activities. The main target of this second conference after the first one in 2005 was to analyze the spatial and functional boundaries of municipal economic activities. The participants came from various fields of science, local public administrations, municipal enterprises, associations and included politicians and others interested in the topic. The presentations covered a broad variety of subjects. On the first conference day, the speakers dealt with the partly controversial attitude of different disciplines such as law, economics, public business administration or sociology towards the local public economy. Other presenters focused on selected municipal services (public transportation, housing).
The second day was dedicated to the topics restrictions on municipal economic activities in Southern Europe, regional effects of municipal enterprises and employee protection in case of privatization. The conference was closed by a panel discussion with distinguished representatives from politics, science and management about the future role of municipal enterprises.
The presentations and discussions showed that the times are changing for the local public sector. In addition, the participants rejected an unrestricted extension of markets or business fields of municipal enterprises as well as the complete privatization of municipal services.

FDI and Domestic Investment: An Industry-level View
Claudia M. Buch
CEPR. Discussion Paper No. 6464,
2007
Abstract
Previous empirical work on the link between domestic and foreign investment provides mixed results which partly depend on the level of aggregation of the data. We argue that the aggregated home country implications of foreign direct investment (FDI) cannot be gauged using firm-level data. Aggregated data, in turn, miss channels through which domestic and foreign activities interact. Instead, industry-level data provide useful information on the link between domestic and foreign investment. We theoretically show that the effects of FDI on the domestic capital stock depend on the structure of industries and the relative importance of domestic and multinational firms. Our model allows distinguishing intra-sector competition from inter-sector linkage effects. We test the model using data on German FDI. Using panel cointegration methods, we find evidence for a positive long-run impact of FDI on the domestic capital stock and on the stock of inward FDI. Effects of FDI on the domestic capital stock are driven mainly by intra-sector effects. For inward FDI, inter-sector linkages matter as well.

Spillover Effects of Spatial Growth Poles - a Reconciliation of Conflicting Policy Targets?
Alexander Kubis, Mirko Titze, Joachim Ragnitz
IWH Discussion Papers,
No. 8,
2007
Abstract
Regional economic policy faces the challenge of two competing policy goals - reducing regional economic disparities vs. promoting economic growth. The allocation of public funds has to weigh these goals particularly under the restriction of scarce financial re- sources. If, however, some region turns out to be a regional growth pole with positive spillovers to its disadvantaged periphery, regional policies could be designed to recon- cile the conflicting targets. In this case, peripheral regions could indirectly participate in the economic development of their growing cores. We start our investigation by defining and identifying such growth poles among German regions on the NUTS 3 administrative level based on spatial and sectoral effects. Using cluster analysis, we determine significant characteristics for the general identification of growth poles. Patterns in the sectoral change are identified by means of the change in the employment. Finally, we analyze whether and to what extent these growth poles ex- ert spatial spillover effects on neighbouring regions and thus mitigate contradictory in- terests in regional public policy. For this purpose, we apply a Spatial-Cross-Regressive- Model (SCR-Model) including the change in the secondary sector which allows to con- sider functional economic relations on the administrative level chosen (NUTS 3).

Aid and Economic Freedom: An Empirical Investigation Using the Heritage Index
Tobias Knedlik, Franz Kronthaler
Journal of Development Perspectives,
No. 3,
2007
Abstract
The paper explores the relationships between economic freedom on the one side and development aid and IMF credit as approximation for conditional aid on the other side. After a short review of current literature, the paper develops a simple panel regression model to evaluate the relationships. In contrast to previous research, our results allow the rejection of the hypothesis that IMF credit increases economic freedom and that development aid is not contributing to economic freedom. It could not be shown that countries can be pushed towards economic freedom by aid conditions. The paper discusses explanations of the empirical findings.
