Abstract
Modern entrepreneurship comprises a mix of bourgeois morale and the striving for adventure: Bourgeois morale implies efficiency, reputation, the rule of the law. And adventure implies new frontiers, the spirit of competition, innovation and a pioneer’s attitude – up to the destruction of competitors. The modern entrepreneur’s social position thus is a ambiguous; the entrepreneur needs a special attitude with respect to economic activity as discussed by Werner Sombard (1913) and Max Weber (1905); society has to accept the positive ethical quality of profit seeking in order to survive. The modern theory of the enterprise promoted by neoclassic theory does not include any of these elements of real entrepreneurship. Industrial organisation theory tries to structure models closer to reality, thus allowing empirical testing. In many aspects, it is based on neoclassic theory, but also accepts the concept of strategic behaviour which includes potential reactions of other market participants in ones own activities. Elements of evolutionary economics, risk theory and modern information theory thus become important. The overarching question of the entrepreneur, who strives for a higher than normal profit in the market becomes: under which conditions should I enter the market and under which conditions will potential entrants do the same? How should I set my prizes and what reactions must I expect? How can I signal friendly behaviour to competitors? How can I differentiate myself from them? What importance do innovations and advertising have? The book roles out these questions in three large chapters on technology and market structure, on prize setting and signalling, and on research, development and innovation. An introduction explains individual behavioural patterns within the societal context – often in a historical perspective. Three methodological chapters introduce the reader into strategic thinking as the core aspect of the industrial organisation theory, the “old industrial organisation theory” and the neoclassic basic models. Each chapter is extended by exercises and tips for solutions.

Equity and Bond Market Signals as Leading Indicators of Bank Fragility
Reint E. Gropp, Jukka M. Vesala, Giuseppe Vulpes
Journal of Money, Credit and Banking,
No. 2,
2006
Abstract
We analyse the ability of the distance to default and subordinated bond spreads to signal bank fragility in a sample of EU banks. We find leading properties for both indicators. The distance to default exhibits lead times of 6-18 months. Spreads have signal value close to problems only. We also find that implicit safety nets weaken the predictive power of spreads. Further, the results suggest complementarity between both indicators. We also examine the interaction of the indicators with other information and find that their additional information content may be small but not insignificant. The results suggest that market indicators reduce type II errors relative to predictions based on accounting information only.

Conditions of knowledge transfer of new staff members in companies – a game theoretical analysis -
Sidonia vonLedebur
Wirtschaft im Wandel,
No. 1,
2006
Abstract
The availability of knowledge is an essential factor for an economy in global competition. New knowledge is often produced at a different place from its implementation. Thus knowledge transfer is necessary. One possible transfer channel is the employment of people with distinct knowledge not yet available in a company. This study analyses the conditions of efficient transfer of new employees in companies with a game-theoretic model.
It is shown that a high additional reward in relation to the additional effort necessary for knowledge transfer enhances the transfer. But other incentives play a significant role as well, e.g. an adequate team size and a good working atmosphere.

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 liberalization of the German electricity market - a sucessful model?
Christian Growitsch, Felix Müsgens
Wirtschaft im Wandel,
No. 12,
2005
Abstract
Die öffentliche Debatte über die Entwicklung der deutschen Strompreise im Anschluß an die Liberalisierung der Energiemärkte 1998 wirft die Frage nach einem Scheitern der Umstrukturierung dieser Märkte auf. Die Analyse der Entwicklung der Strompreise für Haushaltskunden von 1998 bis 2005 zeigt, daß sich die aggregierten Preise heute auf etwa dem selben Niveau wie unmittelbar nach der Liberalisierung der deutschen Energiemärkte (-0,5%) bewegen. Eine solch generelle Betrachtung könnte jedoch aus zwei Gründen in die Irre führen. Einerseits gibt es erhebliche Unterschiede in der Preisentwicklung auf den einzelnen Wertschöpfungsstufen des Stromsektors. Die Erzeugungspreise haben im Zeitablauf beispielsweise eine deutliche Reduktion von ca. 25% erlebt, sind jedoch nach 2001 über ein wettbewerbliches Preisniveau gestiegen. Dem Vorwurf der industriellen Kraftwirtschaft, daß die Großhandelspreise für Strom überhöht seien, kann somit zwar nicht widersprochen werden; für ein grundsätzliches Scheitern der Energiemarktreformen spricht die beobachtbare Entwicklung allerdings auch nicht...

Stochastische Unternehmensmodelle als Kern innovativer Ratingsysteme
Ulrich Blum, Werner Gleißner, Frank Leibbrand
IWH Discussion Papers,
No. 6,
2005
Abstract
In our paper, we analyze, based on a new rating methodology, 105 enterprises from Saxony with respect to their ability to meet their financial obligations. It is based on classical financial-statement approach, a direct inclusion of risk and a stochastic simulation model of enterprise development. The results show that the method used is superior to presently used approaches and that it extends our knowledge of enterprise development. On and above its Basel-II applicability, it is a tool to analyze individual development strategies of firms.

Optimale Geld- und Währungspolitik in Südafrika – Modellierung und Schätzung
Tobias Knedlik
Berichte der Internationalen Wissenschaftliche Vereinigung Weltwirtschaft und Weltpolitik e.V. Vol. 15,
No. 161,
2005
Abstract
THE AIM OF THIS PAPER is to combine the estimation of the Monetary Conditions Index (MCI) with the theoretic modelling of monetary policy rules for open and emerging market economies using the example of South Africa. The idea that monetary policy is not only interested in optimal monetary conditions but also in external stability, constitutes the basis for the analysis. This idea emerged from studying currency crises that are caused by inadequate monetary policy and in particular from the experience of the Asian crisis of 1997/98 and its worldwide spread also to South Africa. The Monetary Conditions Index is a potentially useful tool for the development of monetary policy rules.

The integration of imperfect financial markets: Implications for business cycle volatility
Claudia M. Buch, C. Pierdzioch
Journal of Policy Modeling,
No. 7,
2005
Abstract
During the last two decades, the degree of openness of national financial systems has increased substantially. At the same time, asymmetries in information and other financial market frictions have remained prevalent. We study the implications of the opening up of national financial systems in the presence of financial market frictions for business cycle volatility. In our empirical analysis, we show that countries with more developed financial systems have lower business cycle volatility. Financial openness has no strong impact on business cycle volatility, in contrast. In our theoretical analysis, we study the implications of the opening up of national financial markets and of financial market frictions for business cycle volatility using a dynamic macroeconomic model of an open economy. We find that the implications of opening up national financial markets for business cycle volatility are largely unaffected by the presence of financial market frictions.
