Excess Volatility in European Equity Style Indices - New Evidence
Marian Berneburg
IWH Discussion Papers,
Nr. 16,
2006
Abstract
Are financial markets efficient? One proposition that seems to contradict this is Shiller’s finding of excess volatility in asset prices and its resulting rejection of the discounted cash flow model. This paper replicates Shiller’s approach for a different data set and extends his analysis by testing for a long-run relationship by means of a cointegration analysis. Contrary to previous studies, monthly data for an integrated European stock market is being used, with special attention to equity style investment strategies. On the basis of this analysis’ results, Shiller’s findings seem questionable. While a long-run relationship between prices and dividends can be observed for all equity styles, a certain degree, but to a much smaller extent than in Shiller’s approach, of excess volatility cannot be rejected. But it seems that a further relaxation of Shiller’s assumptions would completely eliminate the finding of an overly strong reaction of prices to changes in dividends. Two interesting side results are, that all three investment styles seem to have equal performance when adjusting for risk, which by itself is an indication for efficiency and that market participants seem to use current dividend payments from one company as an indication for future dividend payments by other firms. Overall the results of this paper lead to the conclusion that efficiency cannot be rejected for an integrated European equity market.

Progressivity and flexibility in developing an effective competition regime: using experiences of Poland, Ukraine and South Africa for developing countries. Forschungsbericht innerhalb des EU-Projektes: Competition Policy Foundations for Trade Reform, Regulatory Reform, and Sustainable Development, 2005

Abstract
The paper discusses the role of the concept of special and differential treatment in the framework of regional trade agreements for the development of a competition regime. After a discussion of the main characteristics and possible shortfalls of those concepts, three case countries are assessed in terms of their experience with progressivity, flexibility, and technical and financial assistance: Poland was led to align its competition laws to match the model of the EU. The Ukraine opted voluntarily for the European model, this despite its intense integration mainly with Russia. South Africa, a developing country that emerged from a highly segregated social fabric and an economy dominated by large conglomerates with concentrated ownership. All three countries enacted (or comprehensively reformed) their competition laws in an attempt to face the challenges of economic integration and catch up development on the one hand and particular social problems on the other. Hence, their experience may be pivotal for a variety of different developing countries who are in negotiations to include competition issues in regional trade agreements. The results suggest that the design of such competition issues have to reflect country-particularities to achieve an efficient competition regime.

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.

Are Botswana and Mozambique ready for CMA enlargement?
Tobias Knedlik
Botswana Journal of Economics,
Nr. 3,
2006
Abstract
The paper elaborates on the appropriateness of a potentially enlarged Common Monetary Area in Southern Africa including Botswana and Mozambique. The theory of optimum currency areas including some extensions by accounting for costs of non-integration and considering the external relations of currency areas are presented. Various indicators such as the structure of the economies, interest rates, inflation rates, exchange rates, factor mobility and trading partners are observed empirically. The paper concludes that current changes in the exchange rate policy of Botswana are expected to lead to increasing, though already high, convergence with CMA countries. Botswana is therefore an appropriate candidate for CMA enlargement. Mozambique is converging towards South Africa but still remains on a lower level. Taking into account the costs of non-integration, however, the target of integration should be formulated for the medium term.

Enhanced Cooperation in an Enlarged EU, CeGE-Discussion Paper No. 53

Abstract
The paper adresses the need for more flexibility in the integration process of the European Union after its recent eastward enlargement. Due to the increasing number of decision-makers and the increasing heterogeneity of economic structures, financial constraints, societal preferences, and political interests, European integration based on the uniformity principle is hardly feasible. In order to avoid a rank growth of integration and yet to strengthen the momentum of flexibility, so-called enhanced cooperation appears to be an appropriate instrument to be applied to the overall integration process. In this context the paper analyzes different possible developments of selected common policies in the EU if enhanced cooperation is practised by a sub-group of EU-members. Based on cluster analysis similarities and distinctions among the EU members with respect to some specific policy realms are elaborated to identify clusters, or clubs, of countries which may apply the instrument of enhanced cooperation in the specific policy fields.

Economies of Scope in European Railways: An Efficiency Analysis
Christian Growitsch, Heike Wetzel
IWH Discussion Papers,
Nr. 5,
2006
Abstract
In the course of railway reforms in the end of the last century, national European governments, as well the EU Commission, decided to open markets and to separate railway networks from train operations. Vertically integrated railway companies – companies owning a network and providing transport services – argue that such a separation of infrastructure and operations would diminish the advantages of vertical integration and would therefore not be suitable to raise economic welfare. In this paper, we conduct a pan-European analysis to investigate the performance of European railways with a particular focus on economies of vertical integration. We test the hypothesis that integrated railways realise economies of joint production and, thus, produce railway services on a higher level of efficiency. To determine whether joint or separate production is more efficient we apply a Data Envelopment Analysis super-efficiency bootstrapping model which relates the efficiency for integrated production to a virtual reference set consisting of the separated production technology. Our findings are that in a majority of European Railway companies exist economies of scope.

A Strategy View on Knowledge in the MNE - Integrating Subsidiary Roles and Knowledge Flows
Björn Jindra
East-West Journal of Economics and Business,
1 & 2
2005
Abstract
We assume knowledge inflows endogenous to subsidiary roles. Integrating organisational and knowledge-based views we propose a new subsidiary typology based on MNE integration-subsidiary capability. We hypothesise that both dimensions are positively associated with knowledge inflows into the focal subsidiary. This prediction is tested with data for 425 subsidiaries. The key findings were: (a) the extent for knowledge inflows differs significantly across all subsidiary roles; (c) it diminishes in a anti-clockwise direction starting in the high integration-high capability quadrant of the IC taxonomy; thus (b) both MNE integration and subsidiary capability drive knowledge inflows, although, the balance shifts more towards integration.
