The European Emissions Trading System: What Have We Learned so Far?
Wilfried Ehrenfeld

No. 3,
2008
Abstract
The IWH occupies with the consequences of the emission trading for the effected companies. The first period of the European Emission Trading System was conceived as a learning phase during which two problems occurred: The first and most obvious one was the surplus of certificates. The incentives to invest in the mitigation of CO2 can therefore be considered to be low. The second problem resulted from the allocation which was entirely for free. While electricity customers had to bear the main financial burden, electricity producers profited as the certificate-prices were obviously added to the electricity-prices as opportunity costs. The analysis comes to the conclusion that it was right to shorten the amount of certificates on the EU-level for the second trade period and to establish the partly sales or auctioning of certificates in German legislation. Furthermore, the simplification of the allocation method in Germany can be considered to be a progress.

The Stability of Bank Efficiency Rankings when Risk Preferences and Objectives are Different
Michael Koetter
European Journal of Finance,
No. 2,
2008
Abstract
We analyze the stability of efficiency rankings of German universal banks between 1993 and 2004. First, we estimate traditional efficiency scores with stochastic cost and alternative profit frontier analysis. Then, we explicitly allow for different risk preferences and measure efficiency with a structural model based on utility maximization. Using the almost ideal demand system, we estimate input- and profit-demand functions to obtain proxies for expected return and risk. Efficiency is then measured in this risk-return space. Mean risk-return efficiency is somewhat higher than cost and considerably higher than profit efficiency (PE). More importantly, rank–order correlation between these measures are low or even negative. This suggests that best-practice institutes should not be identified on the basis of traditional efficiency measures alone. Apparently, low cost and/or PE may merely result from alternative yet efficiently chosen risk-return trade-offs.

Culture as a Base for Efficient Economic Systems
Ulrich Blum
Wirtschaft im Wandel,
No. 2,
2008
Abstract
Globalization puts the German economic model, the so-called social market economy, under pressure. Constituting elements of this model are fundamental social and economic values. Globalization puts some of these values under pressure and creates inefficiencies because the costs of running the social and economic fabric rise. This is an important justification to inquire into the normative foundations of economic efficiency The following article discusses to what extent culture is a base for efficient economic systems. Information theory is regarded as a key element for explaining social change. The arguments are based on institutional economics with a special view on transaction costs and on cooperation structures. It is shown that specific information technologies promote forms of cooperation, which influence institutional arrangements. The related information technologies themselves are part of the cultural system and its value structures. As a consequence, competition among economic systems favours certain combinations of technologies, cultural arrangements and economic systems. In as much as cultural competition precedes economic competition in the sense of a certain way of thinking, the cultural system can be regarded as a strategic competitive parameter for an economy.

Business cycle forecast 2008: German upswing takes a break
Wirtschaft im Wandel,
No. 1,
2008
Abstract
Economic growth in the industrial countries will be much more muted in 2008 than in the past year. One cause is the prolonged oil price hike during 2007. The second and more important cause is the intensification of tensions on world financial markets. Due to problems in the financial sector, credit expansion will slow next year in the euro area as well as in the US. This will dampen demand in the real economy. A significant downswing in the industrial countries, however, is not the most likely scenario: in the US, expansive economic policy and a weak dollar that gives production in the US a competitive edge will prevent the economy from sliding into recession. In the euro area, high profitability of firms and structural improvements in the working of labour markets will help the economy cope with the stronger euro and with higher costs of external financing due to the turmoil in the financial sector. In Germany, the upswing has still not reached the demand of private households. The main reason is that real wages were stagnating in 2007 and will not rise by much in 2008, since inflation has accelerated considerably at the end of last year. In addition, weaker dynamics of external demand will dampen export growth. This and the end of tax incentives for investment at the end of 2007 will dampen investment activity. All in all, the economy will slow down in the first half of 2008. However, chances are good that the upswing will only have taken a break: when the dampening external shocks have ceased, the driving powers of the upswing will prevail; dynamic employment growth is a reflection of the strong confidence of firms. A major risk for employment and for the German economy in general is, however, the possibility that the policy concerning the labour markets changes course; bad omens are the recent the introduction of minimum wages for postal services and the announced extension of unemployment benefits for persons older than 50.

Grenzen des Wettbewerbs im Gesundheitswesen
Ingmar Kumpmann
IWH Discussion Papers,
No. 1,
2008
Abstract
Many health economists demand more competition in the health care system. They focus on the competition between sickness funds for insured and the competition between health care providers for contracts with sickness funds. But they neglect the competition between health care providers for patients which is crucial for medical quality. This third field of competition is in conflict with the two former fields. The empirical evidence concerning the effects of competition on cost and quality is also ambiguous. Thus the mere claim for “more competition” does not do justice to the high complexity of the health care system.

Poland: Strong Domestic Demand Will Drive Economic Activity
Martina Kämpfe
Wirtschaft im Wandel,
No. 12,
2007
Abstract
Domestic demand was the main force behind growth in 2007. The high level of both, gross fixed investments of firms and private consumption, led to extended industrial production capacities and increased demand of imports. Extraordinarily high was the demand for the output of construction firms. Rising employment and wages and the continuing expansion of loans to the household sector supported the private consumption growth. The high levels of capacity utilization coincide with shortages of labour. First responses to this were wage hikes, which pushed the unit labour costs and led to some increase in consumer price inflation. In 2008, expansion of economic activity will continue at only some lower level, driven by investments and consumption.

Reform of Local Municipal Structures: Centralization not only Implicates Advantages
Peter Haug, Claus Michelsen
Wirtschaft im Wandel,
No. 11,
2007
Abstract
The question whether centralized or decentralized municipal structures are more efficient has been discussed, not only in Germany, for a long time primarily under aspects of law and administrative sciences. In this article, we use an economic approach instead. The prevailing theories on interjurisdictional competition are not conclusive about the cost and welfare effects of centralization. Therefore, using the example of Saxony-Anhalt we investigate empirically if there are any significant differences in expenses or personnel between more centralized municipal governance forms (“Einheitsgemeinden”) or rather decentralized forms (“Verwaltungsgemeinschaften”). Our cross-section analysis for selected municipal activities reveals that both types are very similar in their cost and manning structures. Significant differences can be explained rather by different population densities than by the organizational structure. Considering these results we do not recommend a forced amalgamation of the municipalities in Saxony-Anhalt. Especially, if frustration cost or the political transaction cost, which both rise with centralization, are taken into account.

Optimizing knowledge transfer by new employees in companies
Sidonia vonLedebur
Knowledge Management Research and Practice,
No. 4,
2007
Abstract
Companies realize innovations by creating and implementing new knowledge. One possible source of innovative ideas are new employees. Based on an existing game-theoretic model the conditions of efficient knowledge transfer in a team are analyzed. Offering knowledge to a colleague cannot be controlled directly by the company due to information asymmetries. Thus the management has to provide incentives, which motivate the employees to act in favor of the company. The aim of this paper is to show what influences the propensity of the employees to engage in knowledge transfer and how the management can design the incentive structure for optimal transfer. Several factors are relevant, especially the individual costs of participating in the transfer. These consist mainly of the existing absorptive capacity and the working atmosphere. The model is at least partly generalized on more players. The relevance of the adequate team size is shown: too few or too many developers decrease the remaining company profit. A further result is that depending on the cost structure, perfect knowledge transfer is not always best for the profit of the company.

Transport Costs and the Size of Cities: The Case of Russia
Albrecht Kauffmann
Volkswirtschaftliche Diskussionsbeiträge der Wirtschafts- und Sozialwissenschaftlichen Fakultät, Universität Potsdam, Nr. 93,
No. 93,
2007
Abstract
Real costs of freight transportation have strong increased in Russia particularly during the period of price liberalization 1992–93. This paper investigates possible connections between rising transport costs and the evolution of the size structure of the system of cities in the Russian Federation and its federal subjects. Empirical findings suggest that under conditions of a closed system agglomeration processes according to the predictions of the model of Tabuchi et al. (2005) would have taken place especially in the periphere regions of the North and Far East.

The German Upswing Takes a Break
Wirtschaft im Wandel,
2. Sonderausgabe
2007
Abstract
The world economy continues to expand healthily, but risks have increased during summer. The crisis of the housing sector in the US has deepened: A revaluation of mortgage backed assets has triggered turbulences on global financial markets. The institutes expect that financial markets will calm down during the coming months, but that the downswing in the US will slow the pace of the world economy. The economy in the euro area will, in addition, be dampened by the appreciation of the euro. The German economy is, in spite of a restrictive fiscal policy, in a robust upswing. Because wage setting and inflation continues to be moderate, there will be no need for a restrictive monetary policy. Thus the German economy will, due to slower demand from the US and higher costs of financing, lose momentum, but chances are good that the upswing will only take a break. In the coming year private consumption is expected to be the main contributor to growth, because wage incomes will expand strongly. Unemployment will continue to shrink, albeit at a smaller rate than during 2007. Fiscal policy will no longer be restrictive. Economic policy has improved the conditions for growth in Germany; there is, however, still much to do. Public finances have to be consolidated further, but at the same time, public investment has to be strengthened. This can be achieved if public consumptive expenditure growth is limited. The institutes suggest to increase public expenditure by 2% per annum over the cycle in nominal terms; this is, by less than by the trend growth rate of nominal GDP.
The institutes advise against a reversal of the recent labour market reforms. Instead, incentives for taking up jobs should be increased further.
