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.

Research and Development: important source for product innovation also in East Germany
Jutta Günther, François Peglow
Wirtschaft im Wandel,
No. 9,
2007
Abstract
The development and successful introduction of new products is a fundamental feature of a modern knowledge society. After completion of the retrieving technological renewals in East Germany, businesses in the newly-formed German states have to stand up to the competition for marketable concepts and ideas. In doing so, the structural particularities on the strength of transformation are still in force and besides, the embedding of East Germany between high-tech in the West and catching up countries in the East constitutes an additional challenge. This article outlines the innovation activities of East German companies and pursues in the framework of an multivariate analysis to follow up intra-corporate determining factors for product innovations The empirical analysis, employing the IAB establishment panel, shows an active share of innovation participation of companies belonging to the manufacturing industry in East Germany during the years 2002 and 2003. The proportion of companies with product innovation in the newly-formed German states even lies slightly above the reference value for West Germany. Especially companies with an own Research and Development (R&D) department are introducing new products twice as much as companies without an R&D division. The regression analysis proves that own R&D represents the strongest driving force for product innovations in regard to input factors. Moreover, continuing operational education can also be attested a positive impact on innovation activities and emphasizes concurrently the meaning of long-life learning. In reference to business specific characteristics, it stands out that foreign equity participation imposes a significant negative impact of on product innovations. This result, deserving further analysis, indicates the phenomenon of so-called subcontracting.

The Effect of the Iraq War on Foreign Bank Lending to the MENA Region
H. Evren Damar
Emerging Markets Finance and Trade,
No. 5,
2007
Abstract
This paper examines whether a large geopolitical event, such as the war in Iraq, can affect foreign bank lending from developed countries to emerging markets. Using country-level data, the paper analyzes the effects of economic shocks and the Iraq war on the availability of foreign bank credit to five countries in the Middle East and North Africa. The war has had a nonuniform effect on foreign banks: Although the war has led to higher U.S. lending, it has also discouraged British and Italian banks from lending to the region. Implications concerning the stability and reliability of foreign bank credit in the face of increased geopolitical risks are identified and discussed.

The Euro and Cross-Border Banking: Evidence from Bilateral Data
S. Blank, Claudia M. Buch
Comparative Economic Studies,
No. 3,
2007
Abstract
Has the introduction of the Euro fostered financial integration in Europe? We answer this question using a data set of banks’ bilateral foreign assets and liabilities provided by the Bank for International Settlements. The data cover the pre-Euro period (1995–1998) and the post-Euro period (1999–2005). We use information from 10 OECD reporting countries and all OECD recipient countries. Gravity regressions show a positive and significant impact of the Euro on bilateral financial linkages. This effect is stronger and more robust for banks’ foreign assets than for their foreign liabilities.

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.

Inflation and the Divergence of Relative Prices: Evidence from a Cointegration Analysis
Juliane Scharff
AStA - Advances in Statistical Analysis,
No. 2,
2007
Abstract
The relation between inflation and RPV plays a prominent role in explaining the costs of inflation. This study investigates whether the CPI subcategories drift apart more over a period of high inflation rates than during one of low inflation. The wider dispersion of the subcategories is reflected in an increasing number of common stochastic trends in the system of sub price indices. The results for US data as well as for cross-country comparisons indicate that the influence of inflation on the dispersion of relative prices cannot be revealed by counting cointegrating relations. Thus, the number of stochastic trends or cointegrating relations is not a reliable indicator for the distorting effect of inflation on the dispersion of relative prices.

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.

The State of Convergence in SADC
Tobias Knedlik, F. Povel
Monitoring Regional Integration in Southern Africa Yearbook, Vol. 7,
No. 7,
2007
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.
