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.

Capital Stock Approximation using Firm Level Panel Data: A Modified Perpetual Inventory Approach
Steffen Müller
Jahrbücher für Nationalökonomie und Statistik,
No. 4,
2008
Abstract
Many recent studies exploring conditional factor demand or factor substitution issues use firm level panel data. A considerable number of establishment panels contains no direct information on the capital input, necessary for production or cost function estimation. Incorrect measurement of capital leads to biased estimates and casts doubt on any inference on output elasticities or input substitution properties. The perpetual inventory approach, commonly used for long panels, is a method that attenuates these problems. In this paper a modified perpetual inventory approach is proposed. This method provides more reliable measures for capital input when short firm panels are used and no direct information on capital input is available. The empirical results based on a replication study of Addison et al. (2006) support the conclusion that modified perpetual inventory is superior to previous attempts in particular when fixed effects estimation techniques are used. The method thus makes a considerable number of recently established firm panels accessible to more sophisticated production function or factor demand analyses.

A Minimum Wage of 7.50 Euro per Hour Does Particularly Affect Jobs in Business Related Services
Hans-Ulrich Brautzsch, Birgit Schultz
Wirtschaft im Wandel,
No. 3,
2008
Abstract
In the present public debate on the implementation of a minimum wage, different proposals concerning its design and level are discussed. Often, a minimum wage of 7.50 euro per hour is mentioned. Thereby, it is widely unknown how many employees do earn less than 7.50 euro per hour in different branches. Their jobs could be affected by the introduction of a minimum wage. By means of data of the German Socio-Economic Panels Study, it can be shown that the shares of the low-income earners are considerably high in some branches. Especially in Eastern Germany, in branches like retail trades as well as business related services many employees earn less than 7.50 euro per hour. Wage increases on the demanded minimum level would probably cause employment losses in these labour-intensive branches.

Determinants of International Fragmentation of Production in the European Union
Götz Zeddies
IWH Discussion Papers,
No. 15,
2007
Abstract
The last decades were characterized by large increases in world trade, not only in absolute terms, but also in relation to world GDP. This was in large parts caused by increasing exchanges of parts and components between countries as a consequence of international fragmentation of production. Apparently, greater competition especially from the Newly Industrializing and Post-Communist Economies prompted firms in ‘high-wage’ countries to exploit international factor price differences in order to increase their international competitiveness. However, theory predicts that, beside factor price differences, vertical disintegration of production should be driven by a multitude of additional factors. Against this background, the present paper reveals empirical evidence on parts and components trade as an indicator for international fragmentation of production in the European Union. On the basis of a panel data approach, the main explanatory factors for international fragmentation of production are determined. The results show that, although their influence can not be neglected, factor price differences are only one out of many causes for shifting production to or sourcing components from foreign countries.

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.

Factors Accounting for the Enactment of a Competition Law - an Empirical Analysis
Franz Kronthaler, Johannes Stephan
Antitrust Bulletin,
No. 52,
2007
Abstract
This work is concerned with the factors accounting for decisions to enact a national competition law. We first update and enlarge existing data bases of countries that have enacted a competition law. We then identify and discuss the factors that may influence the decision to enact a competition law. Panel-data logit analysis is then used to test a set of hypotheses relating to the factors involved across time and across countries. The results are interpreted in terms of significance and the sign of their influence on the probability that a country enacts. The results shed light on the probability of individual countries, particularly developing countries, taking the step of enactment.

Long-Term Growth Projections for Eastern Germany
Udo Ludwig
Wirtschaft im Wandel,
No. 6,
2007
Abstract
Recent research comes to the conclusion that the eastern part of Germany not only heavily de-pends on its western counterpart, but that it essentially is dying a slow death. Arguments for this point of view reach from deindustrialisation and the lack of Headquarters of national and international Corporations to the rapidly aging society.
The study at hand assumes that economic development in a specific region does not only de-pend on the quantity and quality of its factors of production, but also on the overall conditions in the national economy a region is connected to. The analysis uses a framework in which the regional production factors are limited to the population and its development. Just as produc-tion, output is restricted to the value added of the region. Since data is only available for the ten years between 1995 - 2005, a panel econometric approach was chosen. For this purpose, the 97 spatial planning regions of Germany (Raumordnungsregionen) were divided into four groups according to their economic growth; slightly surprising, nine regions from Central Germany and Brandenburg fall into the top two groups.
The estimation results show that both economic growth in Germany as a whole as well as increases in the regional number of inhabitants positively influence regional value added. Fur-thermore, the impact of national growth is largest in the group with the highest regional value added and lowest in the group with the smallest regional output. On the other hand, lagged values of regional growth have the greatest impact in the low growth group and the smallest impact in the high growth group.
The main result of the study is that regional economic growth will not necessarily stop when the population is shrinking. After 2020, though, the growth rates of the gross domestic prod-uct will decrease. At the same time, the growth disparities between the different regions will not decline, a process aided by the demographic developments in Germany.

Effectiveness of Competition Law: A Panel Data Analysis
Franz Kronthaler
IWH Discussion Papers,
No. 7,
2007
Abstract
The paper explores what macroeconomic factors can tell us about the effectiveness of recently enacted national competition laws. Qualitative evidence suggests that numerous countries fall short in implementing competition law. Furthermore, there seems to be significant differences between countries. To examine what factors might contribute to the explanation of effectiveness of competition law panel regression analysis is used. The results indicate that the level of economic development matters, however the institutional learning curve is also relevant. Furthermore, larger countries should be more concerned with competition advocacy activities than smaller countries and it seems to be the case that the problem of capture of competition law is serious in countries with high levels of corruption.

Local Public Utilities' Profits and Municipal Expenses in Germany: An Empirical Analysis
Peter Haug, Birger Nerré
Proceedings of the 99th Annual Conference on Taxation (November 16-18), Washington DC,
2006
Abstract
German municipalities are currently struggling with growing budget deficits and other financial hardships. From a public choice point of view it seems tempting for vote-maximizing local governments to raise revenues from sources which create fiscal illusion or allow tax exports. An increasingly important revenue source of this kind are profits of local public utilities. In this paper we try to fill an empirical gap and provide data of the development of the profitability over time for selected German local public utilities. Furthermore, we develop and estimate a municipal expenditure function for a panel data set of large German cities . We found some slightly positive relationship between per capita expenses of the municipality and the disposable per capita profits of the local public utilities. This indicates that probably the German municipalities – according to our theoretical considerations – tend to burden their citizens as well as non-voters outside their boundaries with implicit taxes to satisfy their increasing financial needs.

The relationship between unemployment and output in post-communist countries
Hubert Gabrisch, Herbert Buscher
Post-Communist Economies,
2006
Abstract
Unemployment is still disappointingly high in most Central and East European countries, and might be a reflection of the ongoing adjustment to institutional shocks resulting from systemic transition, or it may be caused by high labour market rigidity, or aggregate demand that is too weak. In this paper we have investigated the dynamics of unemployment and output in those eight post-communist countries, which entered the EU in 2004. We used a model related to Okun’s Law; i.e. the first differences in unemployment rates were regressed on GDP growth rates. We estimated country and panel regressions with instrument variables (TSLS) and applied a few tests to the data and regression results. We assume transition of labour markets to be accomplished when a robust relationship exists between unemployment rate changes and GDP growth. Moreover, the estimated coefficients contain information about labour market rigidity and unemployment thresholds of output growth. Our results suggest that the transition of labour markets can be regarded as completed since unemployment responds to output changes and not to a changing institutional environment that destroys jobs in the state sector. The regression coefficients have demonstrated that a high trend rate of productivity and a high unemployment intensity of output growth have been occurring since 1998. Therefore, we conclude that labour market rigidities do not play an important role in explaining high unemployment rates. However, GDP growth is dominated by productivity progress and the employment-relevant component of aggregate demand is too low to reduce the high level of unemployment substantially.
