Abstract
In this paper we test the ability of three of the most popular methods to forecast the South African currency crisis of June 2006. In particular we are interested in the out-ofsample performance of these methods. Thus, we choose the latest crisis to conduct an out-of-sample experiment. In sum, the signals approach was not able to forecast the outof- sample crisis of correctly; the probit approach was able to predict the crisis but just with models, that were based on raw data. Employing a Markov-regime-switching approach also allows to predict the out-of-sample crisis. The answer to the question of which method made the run in forecasting the June 2006 currency crisis is: the Markovswitching approach, since it called most of the pre-crisis periods correctly. However, the “victory” is not straightforward. In-sample, the probit models perform remarkably well and it is also able to detect, at least to some extent, out-of-sample currency crises before their occurrence. It can, therefore, not be recommended to focus on one approach only when evaluating the risk for currency crises.

No. 12,
2007
Abstract
Business incubators (BIs) are local technology and innovation policy measures that have attracted a great deal of attention by cities and municipalities in Eastern Germany. The enthusiasm of local-policy makers has led to a current number of nearly 130 incubator organizations in Eastern Germany. The article is based on a wider research project that focuses on the evaluation of the effectiveness of five BIs in Eastern Germany. In this article, three key issues of BI-effectiveness are concerned: the incubation time of client and graduate companies, the technological competence of supported firms and the share of newly founded firms in the BIs. Empirical results are positive concerning the indicators incubation time and the share of start-ups in the BIs. Deficiencies of the five BIs are found regarding the technological competence of the supported firms. The article concludes with a short outlook on future research questions.

Paradigm Shift in European Competition Law

Wirtschaft im Wandel,
No. 11,
2007
Abstract
During the last decade, European competition law went through several procedural changes, which were mainly influenced by US-American law. Economic criteria rather than legal parameters are now used to evaluate the conduct of firms. Such a “more economic approach” is apparent both in legislation and jurisdiction.
The article discusses the reforms that resulted from the paradigm shift by focusing on the legislation perspective as well as their impact in terms of cartels. One of the most important instruments in European competition policy is nowadays the Leniency Regulation, which was implemented in 1996. Another tool are the renewed Fining Guidelines, which in general will lead to higher fines.
Although European competition law adopted some instruments from American law, there are still major differences between the two jurisdictions. The possibility to impose jail sentences does not exist on a European level yet. However, a few European countries included criminal sanctions in their national laws.

Determinanten des Erfolgs im Transformationsprozess der mittel- und osteuropäischen Länder - eine empirische Würdigung der Beiträge von Karl Wohlmuth
Tobias Knedlik
Ökonomische Systeme im Wandel der Weltwirtschaft/Economic Systems in a Changing World Economy - Festschrift zum 65. Geburtstag von Professor Dr. Karl Wohlmuth,
2007
Abstract
In his academic career Prof Dr Karl Wohlmuth is, among others, concerned with questions of the economics of transformation. In early contributions regarding the transformation process of Eastern European countries, he deducts policy recommendations for a success-ful transformation process. The present paper summarizes the analyses of Wohlmuth and empirically evaluates - as an ex post analysis - determinants of success in the transforma-tion process. The central question is whether the determinants as identified by Wohlmuth had a significant influence on the success of transformation. The results are that the factors ‘reform of the private sector’, ‘liberalization of the labor market’, and ‘fiscal consolidation’ have been of special importance. It could therefore be shown that the factors that have been early identified by Wohlmuth played in deed an important role in the transformation proc-ess. Thus, his recommendations are of relevance for the ongoing process of transformation.

Demographic development and its economic consequences

Wirtschaft im Wandel,
No. 6,
2007
Abstract
Within the next decades, East Germany will continue to face strong demographic challenges. In addition to shrinking, the ageing of population and labour force will more and more affect the economic development of the new Länder. Against this background, the question rises whether the shift of workforce age structure will influence growth and innovation potential as well as structural change. The IWH recently has focused on this topic widely ignored by the research literature so far. On the basis of selected methods and data, the economic impact of workforce ageing was empirically evaluated. The first issue concerns the impact of age on productivity. Based on two separate empirical investigations, the conclusion can be drawn that above a certain stage, age diminishes productivity. But higher levels of experience might partly compensate for this reduction. Secondly, the innovation effects of ageing have been analyzed. Again, significant age effects arise. Employees at the age of about 40 years turn out to be the most innovative part of the workforce. Furthermore, the analysis shows that engineers are particularly subject to age effects. A third study sheds light on the challenging consequences of ageing on entrepreneurship potential. Hence, independently of the increasing problem of skill shortages, ageing itself will unfavourably affect growth, innovation and structural change. Though political options are limited due to the more or less fixed demographic trends, appropriate instruments regarding economic, family and education policy might lower the identified age effects.

Microeconometric Evaluation of Selected ESF-funded ALMP-Programmes
Eva Reinowski, Birgit Schultz
IWH Discussion Papers,
No. 17,
2006
Abstract
The study evaluates different ESF-funded labour market programmes by comparing the labour market status at different points in time after the treatment. In order to solve the selection problem we employ a standard matching algorithm with a multi-dimensional distance measure. The effects of the analyzed programmes (wage subsidies, start-up subsidies and qualification measures for recipients of social welfare) are very heterogeneous. It can be observed that the direct integration into the regular labour market provides an advantage for the supported individuals. Its lasting effects, however, strongly depend on the group of persons being supported, the type of treatment and the employers’ financial share.

Institutional settings of social assistance: What is improved or unsolved by the
Joachim Wilde
Institutionen und Arbeitsmarkt: Messkonzepte, Wirkungszusammenhänge und internationaler Vergleich,
2006
Abstract
The last reform of benefits for long-term unemployed in Germany ("Hartz IV") did not reduce costs. Moreover, the number of recipients is much higher than it was expected before. Therefore, the institutional settings might be less effective than they could be. Initially, the paper describes the institutional changes by the "Hartz IV" reform. Afterwards, these changes are evaluated with respect to their effects on the number of recipients. The evaluation is based on the results of econometric studies concerning the former social assistance. It is pointed out that the reform improved basic conditions and incentives only partly, whereas some of its elements worsened the institutional settings.

Gesamtwirtschaftliche Effekte der Förderung regenerativer Energien, insbesondere der Biomasse - Eine kritische Beurteilung vor dem Hintergrund modelltheoretischer Konzeptionen
Götz Zeddies
Zeitschrift für Umweltpolitik und Umweltrecht 2/2006,
No. 2,
2006
Abstract
Renewable energies are largely promoted in the Federal Republic of Germany by means of political instruments by the federal government as well as by the federal states. However, the effects of promoting renewable energies on growth and employment are politically controversial. On the part of the scientists, the macroeconomic effects of the promotion of renewable energies were already analysed in different studies by various authors. At first sight, even the scientific results do not allow definite conclusions. The reasons for this may be seen in the diversity of the applied empirical methods and models with respect to their closeness and the model assumptions. Against the background of these difficulties, the aim of this paper is to discuss the general problems of macroeconomic policy analyses, to formulate methodical model requirements and to examine important existing scientific studies with respect to these requirements and to evaluate their results.

The coalition treaty from a fiscal point of view
Kristina vanDeuverden
Wirtschaft im Wandel,
No. 12,
2005
Abstract
After weeks of negotiations the coalition finally agreed on the conditions for their political work. Not surprisingly, the coalition agreement is complex and intransparent – with a multitude of single measures far away from a precise definition. Quantifying the programme and estimating resulting cash flows is currently difficult; official calculations are – if at all – only partly available. Anyhow, the contract will form the basis for economic policy during the next four years; therefore its evaluation by now is indispensable. The thin red line of the agreement – not astonishingly when considering the precarious financial situation of the public sector – is consolidation. However, more than 80% of the consolidation volume results from the revenue side. Though one third of this is due to the cutback of tax exemptions, the lion’s share comes from raising tax rates, mainly the VAT standard rate. In contrast, cutting back public expenditure is minor and the agreement clearly comes short of the Koch/Steinbrück proposal; even new tax reliefs are created. The consolidation is almost completely borne by private households. Enterprises as a whole are barely hit. However, they have to wait until 2008 for a reform of company taxation – one of the most pressing problems in this legislative period. To reduce the companies tax burden until the reform starts the conditions for tax depreciation are temporarily relaxed. Anyway, from an international point of view the statutory tax rate is an important signal to enterprises deciding where to invest. Lowering effective tax rates by changing depreciation conditions is intransparent and, thus, will be less effective. Furthermore savings within the public sector are planned to accomplish consolidation; 10 billion Euro should result from efficiency gains and reduced expenditure. Consolidation measures mainly focus on the budget of the federal government. However, Länder and communities will participate in the additional tax revenues. In contrast, social securities will loose – and therefore also the share of employment that is subject to social insurance contribution. Particularly the unemployment insurance will be burdened by the decrease of its premium rate. Besides, the federal government will reduce its grants to the pension funds and most notably the health system. The contract is dominated by fiscal constraints. Cyclical requirements are considered only cursory and pressing structural reforms are put off. The reforms of company’s taxation, of fiscal federalism, of the health system as well as a proceeding reform of the labour market are only proposed. How and when measures in these fields are realised will determine whether fiscal policy can set a new course.

Wirtschaft im Wandel,
No. 14,
2004
Abstract
Die Förderung der beruflichen Weiterbildung ist eines der wichtigsten Instrumente der Arbeitsmarktpolitik in den neuen Bundesländern. Ob damit tatsächlich die Integration in den ersten Arbeitsmarkt beschleunigt wird, ist Gegenstand der aktuellen Diskussion. Welche Personengruppen ihre Beschäftigungschancen durch Weiterbildung besonders verbessern können, wurde bisher allerdings nur selten untersucht. In diesem Beitrag wird eine differenzierte Analyse des Maßnahmeeffekts auf die Arbeitslosigkeitsdauer sächsischer Weiterbildungsteilnehmer vorgestellt, bei der insbesondere auch die Zielgruppen der aktiven Arbeitsmarktpolitik untersucht werden. Damit soll eine Antwort auf die Frage, welche persönlichen, ökonomischen und institutionellen Faktoren den Beschäftigungserfolg der geförderten Maßnahmen beeinflussen, gefunden werden. Für die einzelnen Gruppen lassen sich graduell unterschiedliche Ergebnisse feststellen, was darauf hindeutet, dass die untersuchten Faktoren den Maßnahmeeffekt beeinflussen. Allerdings kann für keine der analysierten Gruppen ein positiver Beschäftigungseffekt beobachtet werden.
