Are Botswana and Mozambique ready for CMA enlargement?
Tobias Knedlik
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.

Network Investment and the Threat of Regulation – Preventing Monopoly Exploitation or Infrastructure Construction?
Ulrich Blum, Christian Growitsch, Niels Krap
IWH Discussion Papers,
No. 7,
2006
Abstract
In summer 2005, the German telecommunication incumbent Deutsche Telekom announced its plans to build a new broadband fibre optics network. Deutsche Telekom decided as precondition for this new network not to be regulated with respect to pricing and third party access. To develop a regulator's strategy that allows investments and prevents monopolistic prices at the same time, we model an incumbent's decision problem under a threat of regulation in a game-theoretical context. The decision whether to invest or not depends on the probability of regulation and its assumed impact on investment returns. Depending on the incumbent's expectation on these parameters, he will decide if the investment is favourable, and which price to best set. This price is below a non-regulated profit maximising price, since the incumbent tries to circumvent regulation. Thus, we show that the mere threat of a regulator's intervention might prevent supernormal profits without actual price regulation. The regulator, on the other hand, can influence both investment decision and the incumbent's price via his signals on regulation probability and price. These signals an be considered optimal, if they simultaneously allow investment and minimize the incumbent's price.

Abstract
Im ostdeutschen Verarbeitenden Gewerbe haben zu Jahresbeginn die Auftriebskräfte weiter die Oberhand, wie die IWH-Befragung unter rund 300 Industrieunternehmen signalisiert. So setzte sich die seit einigen Monaten anhaltende Erwärmung des Geschäftsklimas auch im Januar fort, wobei die Urteile zu Lage und Aussichten zusammengenommen den Stand vom November 2005 um fünf Saldenpunkte übertreffen. Dahinter verbirgt sich eine gegenläufige Entwicklung der beiden Komponenten: die Geschäftslage für das Verarbeitende Gewerbe insgesamt hat sich gegenüber der vergangenen Befragung verschlechtert, wohingegen die Geschäftserwartungen erheblich positiver als in der Vorperiode ausfallen.

IWH construction survey East Germany at the beginning of 2006: slightly more stable profitability, expectations less pessimistic
Brigitte Loose
Wirtschaft im Wandel,
No. 2,
2006
Abstract
Aufgrund von Sonderfaktoren, wie Vorzieheffekte infolge der Kürzung der Eigenheimzulage, Restmaßnahmen zur Beseitigung der Flutschäden und einzelne Großprojekte, wurde die bis 2002 beobachtete steile Abwärtsbewegung der Baunachfrage auch im Jahr 2005 abgebremst. Die Rückgänge waren sowohl im Wohnungsbau als auch im Nichtwohnbau mit etwa 6% nahezu so hoch wie im Jahr zuvor. Laut Umfrage des IWH im Dezember 2005 hat diese Entwicklung zu einer Stabilisierung der Ertragslage im Baugewerbe geführt. Die Bauunternehmen verharren in weit geringerem Maße als im Jahr zuvor in der Verlustzone. Zugleich ist die Fluktuation innerhalb der Gruppe der Gewinnunternehmen geringer geworden. Für das laufende Jahr 2006 bleiben die befragten Unternehmen zwar in der überwiegenden Mehrheit skeptisch, die erwarteten Einbußen fallen aber mit etwa 2½ Prozent geringer aus als im Jahr zuvor.

Investment and Internal Finance: Asymmetric Information or Managerial Discretion?
Hans Degryse, Abe de Jong
International Journal of Industrial Organization,
No. 1,
2006
Abstract
This paper examines the investment-cash flow sensitivity of publicly listed firms in The Netherlands. Investment-cash flow sensitivities can be attributed to overinvestment resulting from the abuse of managerial discretion, but also to underinvestment due to information problems. The Dutch corporate governance structure presents a number of distinctive features, in particular the limited influence of shareholders, the presence of large blockholders, and the importance of bank ties. We expect that in The Netherlands, the managerial discretion problem is more important than the asymmetric information problem. We use Tobin's Q to discriminate between firms with these problems, where LOW Q firms face the managerial discretion problem and HIGH Q firms the asymmetric information problem. As hypothesized, we find substantially larger investment-cash flow sensitivity for LOW Q firms. Moreover, specifically in the LOW Q sample, we find that firms with higher (bank) debt have lower investment-cash flow sensitivity. This finding shows that leverage, and particularly bank debt, is a key disciplinary mechanism which reduces the managerial discretion problem.

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.

The unemployment-growth relationship in transition countries
Hubert Gabrisch, Herbert Buscher
IWH Discussion Papers,
No. 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.

The Economics of Restructuring the German Electricity Sector
Christian Growitsch, Felix Müsgens
Zeitschrift für Energiewirtschaft,
No. 3,
2005
Abstract
The debate about the development of German electricity prices after the liberalization of energy markets in 1998 raises the question of failures in market restructuring. However, a general statement would be misleading for two main reasons. Firstly, the price development, analyzed for the exemplary case of household prices, 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%).

An analysis of household electricity price developments in Germany since liberalization

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%).

Technology spillovers from foreign investors in transition economies - are the effects still expected?
Jutta Günther
Economic and business review,
No. 1,
2005
Abstract
While it is widely acknowledged that there is a technology transfer from parent companies to foreign subsidiaries in central East European countries, there is no clear cut evidence for technology spillovers in favour of domestic companies so far. The paper presents a theoretical framework for how spillover mechanisms are turned into a reality and outlines empirical findings on technology spillovers for transition economies based on a comprehensive literature review. Against the background of an empirical qualitative study, the paper provides firm level explanations for the obvious lack of technology spillovers. Policy oriented issues will be discussed in the conclusions.
