Monitoring Regional Integration in Southern Africa Yearbook, Vol. 7,
No. 7,

Abstract
The Southern African Development Community (SADC) Treaty established an integration agenda for the grouping culminating in the introduction of a common currency by 2018. By determining the degree of macroeconomic convergence across countries it becomes possible to draw conclusions with respect to the feasibility of the envisaged integration agenda of a regional integration scheme. In order to test for convergence among southern African countries the panel unit root test proposed by Im, Pesaran, and Shin (2003) is conducted. The results of the convergence analysis suggest that countries converge towards South Africa.

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.

Threshold for employment and unemployment. A spatial analysis of German RLM's 1992-2000
Christian Dreger, Reinhold Kosfeld
External Publications,
2006
Abstract
Changes in production and employment are closely related over the course of the business cycle. However, as exemplified by the laws of Verdoorn (1949, 1993) and Okun (1962, 1970), thresholds seem to be present in the relationship. Due to capacity reserves of the firms, output growth must exceed certain levels for the creation of new jobs or a fall in the unemployment rate. While Verdoorn's law focuses on the growth rate of output sufficient for an increase in employment, in Okun's law, the fall in the unemployment rate becomes the focus of attention. In order to assess the future development of employment and unemployment, these thresholds have to be taken into account. They serve as important guidelines for policymakers. In contrast to previous studies, we present joint estimates for both the employment and unemployment threshold. Due to demographic patterns and institutional settings on the labour market, the two thresholds can differ, implying that minimum output growth needed for a rise in employment may not be sufficient for a simultaneous drop in the unemployment rate. Second, regional information is considered to a large extent. In particular, the analysis is carried out using a sample of 180 German regional labour markets, see Eckey (2001). Since the cross-sections are separated by the flows of job commuters, they correspond to travel-to-work areas. Labour mobility is high within a market, but low among the entities. As the sectoral decomposition of economic activities varies across the regions, the thresholds are founded on a heterogeneous experience, leading to more reliable estimates.The contribution to the literature is twofold. First, to the best of our knowledge, no previous paper has investigated a similar broad regional dataset for the German economy as a whole before. By using a panel dataset, information on the regional distributions around the regression lines as well as theirs positional changes is provided for each year. Second, the methods applied are of new type. They involve a mixture of pooled and spatial econometric techniques. Dependencies across the regions may result from common or idiosyncratic (region specific) shocks. In particular, the eigenfunction decomposition approach suggested by Griffith (1996, 2000) is used to identify spatial and non-spatial components in regression analysis. As the spatial pattern may vary over time, inference is conducted on the base of a spatial SUR model. Due to this setting, efficient estimates of the thresholds are obtained. With the aid of a geographic information system (GIS) variation of the spatial components can be made transparent. With Verdoorn’s and Okun’s law the figures show some significant patterns become obvious over time. In respect to Verdoorn’s law, for instance, a stripe of high values in the north-western part from Schleswig-Holstein via Lower Saxony and North Rhine Westfalia to Rhineland Palatinate is striking in all years but 1994 and 1995. In most periods the spatial component is likewise concentrated in Saxony. Clusters of low values can be found in northern Bavaria and, in some periods, in Thüringen and Mecklenburg-Vorpommern. Other parts of Germany appear to be more fragmented consisting of relative small clusters of low, medium and high values of the spatial component. With Okun’s law some changing spatial patterns arise. In all, spatially filtering provides valuable insights into the spatial dimensions of the laws of Verdoorn and Okun.

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.

Longterm development of return on assets – an empirical panel data analysis
Olaf Neubert
Wirtschaft im Wandel,
No. 5,
2006
Abstract
One of the basic propositions of economic theory is the fact that competition does not allow permanent very high or very low returns. But how can the permanent surplus gain of a monopolist be distinguished from innovation gains? In which markets is a regulatory interference necessary? Contrary to the static analysis, the concept of dynamic competition explicitly considers the temporal development of return and gain. An entrepreneur can achieve an advantage over the competitors through new products or new production processes. Hence arising innovation gains function as incentives for imitators to join the development which in turn leads to a reduction of the surplus gains. Thus, these gains are not contradictory to an effective competition. On the basis of annual balance sheets of German firms, this article analyses the temporal development of returns on assets. It is to evaluate whether the adaptation process assumed by Schumpeter that matches very high and very low gains with a longterm level can be confirmed, and how fast this process works. The average industry returns of the manufacturing industry show a convergence to a longterm level. During this process, an average of 40% of the deviation from the longterm level are melted every year. However, the analysis of company returns shows longterm differences. The adaptation rate of companies, 50%, is significantly higher compared to the industry value. The analysis of the connection between the adaptation rate and the longterm return level of companies proves that companies which face above-average competition strength obtain a higher longterm return level than other companies. When firms operate within markets with high stress of competition they do not achieve below-average returns but rather significantly above-average returns in the long term.

Factors accounting for the enactment of a competition law – an empirical analysis
Franz Kronthaler, Johannes Stephan
One-off Publications,
No. 6,
2005
Abstract
The paper is concerned with the factors that account for decisions to enact a national competition law. In a first step, the paper updates and enlarges the existing data bases of countries that have enacted a competition law. The paper then identifies and discusses possible factors that influence the decision to enact a competition law. In a third step, the method of panel-data logit analysis is employed to test a set of hypothesis pertaining to the factors across the time dimension and across countries. The results of this analysis are interpreted in terms of significance and in terms of the sign of their influence on the probability of a country to enact. Given generality of the analysis, the results can shed light on the probability of individual countries, and in particular developing countries, to actually take the step of enactment.

Health care expenditures in OECD countries. A panel unit root and cointegration analysis
Christian Dreger, Hans-Eggert Reimers
External Publications,
2005
Abstract
Im Papier wird der Zusammenhang zwischen Gesundheitsausgaben und Bruttoinlandsprodukt mit panelökonometrischen Verfahren für 21 OECD Länder untersucht. Im Gegensatz zu anderen Studien werden alternative Indikatoren des medizinisch-technischen Fortschritts einbezogen (Lebenserwartung, Kindersterblichkeit, Anteil älterer Menschen). Durch die Erweiterung des Modells mit diesen Indikatoren ergibt sich eine Einkommenselastizität der Gesundheitsausgaben von 1. Gesundheit kann daher nicht als Luxusgut angesehen werden: nachdem für den medizoinisch-technischen Fortschritt kontrolliert wird, entwickeln sich die Gesundheitsausgaben proportional zum Einkommen.

Firm-Specific Determinants of Productivity Gaps between East and West German Industrial Branches
Johannes Stephan, Karin Szalai
IWH Discussion Papers,
No. 183,
2003
Abstract
Industrial productivity levels of formerly socialist economies in Central East Europe (including East Germany) are considerably lower than in the more mature Western economies. This research aims at assessing the reasons for lower productivities at the firm level: what are the firm-specific determinants of productivity gaps. To assess this, we have conducted an extensive field study and focussed on a selection of two important manufacturing industries, namely machinery manufacturers and furniture manufacturers, and on the construction industry. Using the data generated in field work, we test a set of determinant-candidates which were derived from theory and prior research in that topic. Our analysis uses the simplest version of the matched-pair approach, in which first hypothesis about relevant productivity level-determinants are tested. In a second step, positively tested hypothesis are further assessed in terms of whether they also constitute firm-specific determinants of the apparent gaps between the firms in our Eastern and such in our Western panels. Our results suggest that the quality of human capital plays an important role in all three industrial branches assessed. Amongst manufacturing firms, networking activities and the use of modern technologies for communication are important reasons for the lower levels of labour productivity in the East. The intensity of long-term strategic planning on behalf of the management turned out to be relevant only for machinery manufacturers. Product and process innovations unexpectedly exhibit an ambiguous picture, as did the extent of specialisation on a small number of products in the firms’ portfolio and the intensity of competition.
