Are Botswana and Mozambique ready for CMA enlargement?

Botswana Journal of Economics,
No. 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

2006
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.

Determinants of employment - the macroeconomic view
Christian Dreger, Heinz P. Galler, Ulrich (eds) Walwai
Schriften des IWH,
No. 22,
2005
Abstract
The weak performance of the German labour market over the past years has led to a significant unemployment problem. Currently, on average 4.5 mio. people are without a job contract, and a large part of them are long-term unemployed. A longer period of unemployment reduces their employability and aggravates the problem of social exclusion.
The factors driving the evolution of employment have been recently discussed on the workshop Determinanten der Beschäftigung – die makroökonomische Sicht organized jointly by the IAB, Nuremberg, and the IWH, Halle. The present volume contains the papers and proceedings to the policy oriented workshop held in November 2004, 15-16th. The main focus of the contributions is twofold. First, macroeconomic conditions to stimulate output and employment are considered. Second, the impacts of the increasing tax wedge between labour costs and the take home pay are emphasized. In particular, the role of the contributions to the social security system is investigated.
In his introductory address, Ulrich Walwei (IAB) links the unemployment experience to the modest path of economic growth in Germany. In addition, the low employment intensity of GDP growth and the temporary standstill of the convergence process of the East German economy have contributed to the weak labour market performance. In his analysis, Gebhard Flaig (ifo Institute, München) stresses the importance of relative factor price developments. A higher rate of wage growth leads to a decrease of the employment intensity of production, and correspondingly to an increase of the threshold of employment. Christian Dreger (IWH) discusses the relevance of labour market institutions like employment protection legislation and the structure of the wage bargaining process on the labour market outcome. Compared to the current setting, policies should try to introduce more flexibility in labour markets to improve the employment record. The impact of interest rate shocks on production is examined by the paper of Boris Hofmann (Deutsche Bundesbank, Frankfurt). According to the empirical evidence, monetary policy cannot explain the modest economic performance in Germany. György Barabas and Roland Döhrn (RWI Essen) have simulated the effects of a world trade shock on output and employment. The relationships have been fairly stable over the past years, even in light of the increasing globalization. Income and employment effects of the German tax reform in 2000 are discussed by Peter Haan and Viktor Steiner (DIW Berlin). On the base of a microsimulation model, household gains are determined. Also, a positive relationship between wages and labour supply can be established. Michael Feil und Gerd Zika (IAB) have examined the employment effects of a reduction of the contribution rates to the social security system. To obtain robust results, the analysis is done under alternative financing scenarios and with different macroeconometric models. The impacts of allowances of social security contributions on the incentives to work are discussed by Wolfgang Meister and Wolfgang Ochel (ifo München). According to their study, willingness to work is expected to increase especially at the lower end of the income distribution. The implied loss of contributions could be financed by higher taxes.

System economic theses and economic policy means to promote economic growth in central and east Germany

Wirtschaft im Wandel,
No. 8,
2005
Abstract
Der wirtschaftliche Aufschwung der neuen Bundesländer stagniert seit gut acht Jahren, obwohl jährlich etwa 80 Mrd. Euro an Transfers in die neuen Länder fließen. Die unbefriedigende Entwicklung dort, aber inzwischen auch in einigen westdeutschen Regionen, stellt zunehmend eine Bedrohung für den gesamtdeutschen wirtschaftlichen Wohlstand und die Leistungsfähigkeit des Landes dar. Aber die Wachstumsdefizite Deutschlands finden ihre Ursache nicht nur im Osten: Sie sind weitgehend dem im Sinne des globalen Wettbewerbs fehlangepaßten deutschen Ordnungsrahmen geschuldet. Alle drei föderalen Ebenen sollten sich gefordert fühlen, dieser Entwicklung mit Kreativität entgegenzutreten, eine jede auf ihren spezifischen, durch Föderalismus und Subsidiaritätsprinzip gegebenen Feldern, weil Ursachen und Folgen ineinander verfließen...

Non-market Allocation in Transport: A Reassessment of its Justification and the Challenge of Institutional Transition
Ulrich Blum
50 Years of Transport Research: Experiences Gained and Major Challenges Ahead,
2005
Abstract
Economic theory knows two systems of coordination: through public choice or through the market principle. If the market is chosen, then it may either be regulated, or it may be fully competitive (or be in between these two extremes). This paper first inquires into the reasons for regulation, it analyses the reasons for the important role of government in the transportation sector, especially in the procurement of infrastructure. Historical reasons are seen as important reasons for bureaucratic objections to deregulation. Fundamental economic concepts are forwarded that suggest market failure and justify a regulatory environment. The reasons for regulation cited above, however, may be challenged; we forward theoretical concepts from industrial organization theory and from institutional economics which suggest that competition is even possible on the level of infrastructure. The transition from a strongly regulated to a competitive environment poses problems that have given lieu to numerous failures in privatization and deregulation. Structural inertia plays an important role, and the incentive-compatible management of infrastructure is seen as the key element of any liberal transportation policy. It requires that the setting of rules on the meta level satisfies both local and global efficiency ends. We conclude that, in market economies, competition and regulation should not be substitutes but complements. General rules, an "ethic of competition" have to be set that guarantee a level playing field to agents; it is complimented by institutions that provide arbitration in case of misconduct.

Negotiated Third Party Access - an Industrial Organisation Perspective
Christian Growitsch, Thomas Wein
European Journal of Law and Economics,
2005
Abstract
In the course of the liberalization of European energy markets, the German government opted – diverging from all other European countries – for Negotiated Third-Party Access. In this article we analyze if, theoretically, this institutional regime can be superior to regulation. We review empirically whether certain aspects of the actual implementation, in particular publication of the network access charges for each network supplier, facilitated or inhibited competition. In the first place we reconsider previous research, showing that NTPA can – under certain conditions – be economically effective. Our empirical analysis shows that the duty of publishing access charges supported market transparency and imposed a regulatory threat, particularly to suppliers with significantly above-average charges. On the other hand observable price adjustments over time serve as an indicator of tacit collusion. Although the expensive suppliers cut their prices, the cheaper ones raised theirs.

An analysis of household electricity price developments in Germany since liberalization
Christian Growitsch, Felix Müsgens
Externe Publikationen,
2005
Abstract
Despite the liberalization of energy markets in 1998, household electricity prices in 2004 are nearly the same as 1998, indicating a failure of market restructuring. However, such a general consideration is misleading for two main reasons. Firstly, the price development shows significant differences among the stages of the value chain. Secondly, the underlying cost structure might have changed from 1998 to 2004. While such effects can be expected to level out over time, they can distort the comparison of a small period of observation. For these reasons, we analyzed the different price components at a detailed level, finding a considerable price reduction of about 32% in generation and a much lower reduction of 13% in transmission and distribution tariffs. These decreases have been mostly compensated by a significant increase in taxes and subsidies (+56%).

Network Access Charges, Vertical Integration, and Property Rights Structure
Christian Growitsch, Thomas Wein
Energy Economics,
No. 2,
2005
Abstract
After the deregulation of the German electricity markets in 1998, the German government opted for a regulatory regime called negotiated third party access, which would be subject to ex post control by the federal cartel office. Network access charges for new competitors are based on contractual arrangements between energy producers and industrial consumers. As the electricity networks are incontestable natural monopolies, the local and regional network operators are able to set (monopolistic) charges at their own discretion, limited only by their concerns over possible interference by the federal cartel office (Bundeskartellamt). In this paper we analyse if there is evidence for varying charging behaviour depending on a supplier`s economic independence (structure of property rights) or its level of vertical integration. For this purpose we hypothesise that incorporated and vertically integrated suppliers set different charges than independent utility companies. Multivariate estimations show a relation between network access charges and the network operator’s economic independence as well as level of vertical integration. On the low voltage level, for an estimated annual consumption of 1700 kW/h, vertically integrated firms set – as predicted by our hypothesis - significantly lower access charges than vertically separated suppliers, whereas incorporated network operators charge significantly higher charges compared to independent suppliers. There is insufficient evidence available to confirm these results for other consumptions or voltage levels.

Analysis of statements made in favour of and against the adoption of competition law in developing and transition economies
Johannes Stephan, Franz Kronthaler, Frank Emmert
Einzelveröffentlichungen,
No. 9,
2005
Abstract
The paper is concerned with documenting and assessing statements made by policymakers, opinion formers, and other stakeholders in favour and against the adoption of competition laws with particular reference to transition and developing countries which have not yet enacted these kind of laws. For example, claims that competition enforcement might reduce the inflow of foreign direct investment, or that other policies are successfully used as substitutes for competition law, are assessed. In a first step, the method of generalized analysis structures the list of statements around core issues of common features to make them accessible to further interpretation and assessment. The paper shows that some claims are in fact country or region specific, and specific to the development level of the respective countries. In a second step, the core issues are assessed according to economic and legal criteria. Since the analysis focuses on transition and developing countries, the criteria for economic assessment are predominantly economic growth and development issues, but also include the economic coherency of a set of claims submitted by stakeholders in a given country. The criteria for legal assessment include whether claims are problematic in light of WTO-principles, or are even born out of a political objective which is incompatible with the spirit, if not the letter of WTO-rules.
