Effectiveness of Competition Law: A Panel Data Analysis
Franz Kronthaler
IWH Discussion Papers,
Nr. 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.

Where enterprises lead, people follow? Links between migration and FDI in Germany
Claudia M. Buch, J. Kleinert, Farid Toubal
European Economic Review,
Nr. 8,
2006
Abstract
Standard neoclassical models of economic integration are based on the assumptions that capital and labor are substitutes and that the geography of factor market integration does not matter. Yet, these two assumptions are violated if agglomeration forces among factors from specific source countries are at work. Agglomeration implies that factors behave as complements and that the country of origin matters. This paper analyzes agglomeration between capital and labor empirically. We use state-level German data to answer the question whether and how migration and foreign direct investment (FDI) are linked. Stocks of inward FDI and of immigrants have similar determinants, and the geography of factor market integration matters. There are higher stocks of inward FDI in German states hosting a large foreign population from the same country of origin. This agglomeration effect is confined to higher-income source countries.

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.

Who Invests in Training if Contracts are Temporary? - Empirical Evidence for Germany Using Selection Correction
Jan Sauermann
IWH Discussion Papers,
Nr. 14,
2006
Abstract
This study deals with the effect of fixed-term contracts on work-related training. Though previous studies found a negative effect of fixed-term contracts on the participation in training, from the theoretical point of view it is not clear whether workers with fixed-term contracts receive less or more training, compared to workers with permanent contracts. In addition to the existing strand of literature, we especially distinguish between employer- and employee-financed training in order to allow for diverging investment patterns of worker and firm. Using data from the German Socio-Economic Panel (GSOEP), we estimate a bivariate probit model to control for selection effects that may arise from unobservable factors, affecting both participation in training and holding fixed-term contracts. Finding negative effects for employer-sponsored, as well as for employee-sponsored training, leads us to conclude that workers with fixed-term contracts do not compensate for lower firm investments.

Vertical Intra-industry Trade between EU and Accession Countries
Hubert Gabrisch
IWH Discussion Papers,
Nr. 12,
2006
Abstract
The paper analyses vertical intra-industry trade between EU and Accession countries, and concentrates on two country-specific determinants: Differences in personal income distribution and in technology. Both determinants have a strong link to national policies and to cross-border investment flows. In contrast to most other studies, income distribution is not seen as time-invariant variable, but as changing over time. What is new is also that differences in technology are tested in comparison with cost advantages from capital/labour ratios. The study applies panel estimation techniques with GLS. Results show country-pair fixed effects to be of high relevance for explaining vertical intraindustry trade. In addition, bilateral differences in personal income distribution and their changes are positive related to vertical intra-industry trade in this special regional integration framework; hence, distributional effects of policies matter. Also, technology differences turn out to be positively correlated with vertical intra-industry trade. However, the cost variable (here: relative GDP per capita) shows no clear picture, particularly not in combination with the technology variable.

Clustering or Competition? The Foreign Investment Behavior of German Banks
Claudia M. Buch, A. Lipponer
International Journal of Central Banking,
2006
Abstract
Banks often concentrate their foreign direct investment (FDI) in certain countries. This clustering of activities could reflect either the attractiveness of a particular country or agglomeration effects. To find out which of the two phenomena dominates, we need to control for country-specific factors. We use new bank-level data on German banks’ FDI for the 1996-2003 period.We test whether the presence of other banks has a positive impact on the entry of new banks. Once we control for the attractiveness of a country through fixed effects, the negative impact of competition dominates. Hence, pure clustering effects are rather unimportant.

Forced to Freedom? Empirical Relations between Aid and Economic Freedom
Tobias Knedlik, Franz Kronthaler
IWH Discussion Papers,
Nr. 8,
2006
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 on the issue of economic development, economic freedom, aid, and IMF credit, the paper develops a simple panel regression model to evaluate the relationship between “economic freedom” as dependent variable and “aid” and “IMF credit” as independent variables. The estimation is based upon data taken from the World Bank’s World Development Indicators and the Heritage Index of Economic Freedom. In contrast to previous research, our results allow the rejection of the hypothesis that IMF credit increases economic freedom and that aid is not contributing to economic freedom. The estimation results suggest that, firstly, aid is positively correlated with economic freedom, and secondly, that IMF credit is negatively correlated with economic freedom. Taking IMF credit as proxy for conditional aid, we conclude that for the period of observation it could not be shown that countries can be forced to economic freedom by aid conditions.

Business Cycles and FDI: Evidence from German Sectoral Data
Claudia M. Buch, A. Lipponer
Review of World Economics,
Nr. 4,
2005
Abstract
Globalization has affected business cycle developments in OECD countries and has increased activities of firms across national borders. This paper analyzes whether these two developments are linked. We use a new firm-level data set on the foreign activities of German firms to test whether foreign activities are affected by business cycle developments. We aggregate the data by the sector of the reporting firm, the sector of the foreign affiliate, and the host country. Data are annual and cover the period 1989–2002. We find that German outward FDI increases in response to positive cyclical developments abroad and in response to a real depreciation of the domestic currency.

The unemployment-growth relationship in transition countries
Hubert Gabrisch, Herbert Buscher
IWH Discussion Papers,
Nr. 5,
2005
Abstract
Does the disappointingly high unemployment in Central and East European countries reflect non-completed adjustment to institutional shocks from transition to a market economy, or is it the result of high labour market rigidities, or rather a syndrome of too weak aggregate demand and output? In the case of transitional causes, unemployment is expected to decline over time. Otherwise, it would pose a challenge to the European Union, particular in case of accession countries, for it jeopardizes the ambitious integration plans of, and may trigger excessive migration to the Union. In order to find out which hypothesis holds 15 years after transition has started, we analyze the unemploymentgrowth dynamics in the eight new member countries from Central-Eastern Europe. The study is based on country and panel regressions with instrument variables (TSLS). The results suggest to declare the transition of labour markets as completed; unemployment responds to output and not to a changing institutional environment for job creation. The regression coefficients report a high trend rate of productivity and a high unemployment intensity of output growth since 1998. The conclusion is that labour market rigidities do not to play an important role in explaining high unemployment rates. Rather, GDP growth is dominated by productivity progress, while the employment relevant component of aggregate demand is too low to reduce substantially the high level of unemployment.

Panel Seasonal Unit Root Test: Further Simulation Results and An Application to Unemployment Data
Christian Dreger, Hans-Eggert Reimers
AStA - Advances in Statistical Analysis,
Nr. 3,
2005
Abstract
In dieser Arbeit wird der saisonale Einheitswurzeltests von Hylleberg et al. (1990) auf heterogene Panel verallgemeinert. Die Prozedur folgt dem Ansatz von Im, Pesaran and Shin (2002) und wird in der Arbeit von Otero et al. (2004) unabhängig von diesem Beitrag vorgeschlagen. Die abgeleiteten Teststatistiken werden dargestellt und kritische Werte mit Hilfe von Simulationen ermittelt. Die Eigenschaften der Tests werden für verschiedene deterministische und dynamische Spezifikationen untersucht. Es zeigt sich, dass für kleine Zeitdimensionen die Güte der Tests auch dann gering ist, wenn die Querschnittsdimension wächst. Bei einer empirischen Analyse erscheint es notwendig, das der Datensatz eine größere Zeitdimension als Querschnittsdimension hat. Das Verfahren wird auf die in Quartalen vorliegenden Arbeitslosenquoten industrialisierter Staaten angewendet. Obwohl in einigen Ländern saisonale Einheitswurzeln gefunden werden, wird die Nullhypothese von saisonalen Einheitswurzeln im Panel abgelehnt. Die Nullhypothese einer Einheitswurzel für die Nullfrequenz wird jedoch im Panel nicht abgelehnt, sodass sich Evidenz für Hysteresiseffekte ergibt.
