Stochastic Income Statement Planning and Emissions Trading
Henry Dannenberg, Wilfried Ehrenfeld
Abstract
Since the introduction of the European CO2 emissions trading system (EU ETS), the
development of CO2 allowance prices is a new risk factor for enterprises taking part in this system. In this paper, we analyze how risk emerging from emissions trading can be considered in the stochastic profit and loss planning of corporations. Therefore we explore which planned figures are affected by emissions trading. Moreover, we show a way to model these positions in a planned profit and loss account accounting for uncertainties and dependencies. Consequently, this model provides a basis for risk assessment and investment decisions in the uncertain environment of CO2 emissions trading.

Monopsonistic Labour Markets and the Gender Pay Gap: Theory and Empirical Evidence
Boris Hirsch
Lecture Notes in Economics and Mathematical Systems,
Nr. 639,
2010
Abstract
This book investigates models of spatial and dynamic monopsony and their application to the persistent empirical regularity of the gender pay gap. Theoretically, the main conclusion is that employers possess more monopsony power over their female employees if women are less driven by pecuniary considerations in their choice of employers than men. Employers may exploit this to increase their profits at the detriment of women’s wages. Empirically, it is indeed found that women’s labour supply to the firm is less wage-elastic than men’s and that at least a third of the gender pay gap in the data investigated may result from employers engaging in monopsonistic discrimination. Therefore, a monopsonistic approach to gender discrimination in the labour market clearly contributes to the economic understanding of the gender pay gap. It not only provides an intuitively appealing explanation of the gap from standard economic reasoning, but it is also corroborated by empirical observation.

Monopolistic Competition and Costs in the Health Care Sector
Ingmar Kumpmann
IWH Discussion Papers,
Nr. 17,
2009
Abstract
Competition among health insurers is widely considered to be a means of enhancing efficiency and containing costs in the health care system. In this paper, it is argued that this could be unsuccessful since health care providers hold a strong position on the market for health care services. Physicians exert a type of monopolistic power which can be described by Chamberlin’s model of monopolistic competition. If many health insurers compete with one another, they cannot counterbalance the strong bargaining position of the physicians. Thus, health care expenditure is higher, financing either extra profits for physicians or a higher number of them. In addition, health insurers do not have an incentive to contract selectively with health care providers as long as there are no price differences between physicians. A monopolistic health insurer is able to counterbalance the strong position of physicians and to achieve lower costs.

Regional Growth and Finance in Europe: Is there a Quality Effect of Bank Efficiency?
Iftekhar Hasan, Michael Koetter, Michael Wedow
Journal of Banking and Finance,
Nr. 8,
2009
Abstract
In this study, we test whether regional growth in 11 European countries depends on financial development and suggest the use of cost- and profit-efficiency estimates as quality measures of financial institutions. Contrary to the usual quantitative proxies of financial development, the quality of financial institutions is measured in this study as the relative ability of banks to intermediate funds. An improvement in bank efficiency spurs five times more regional growth then an identical increase in credit does. More credit provided by efficient banks exerts an independent growth effect in addition to direct quantity and quality channel effects.

Effects of Heterogeneity on Bank Efficiency Scores
J. W. B. Bos, Michael Koetter, James W. Kolari, Clemens J. M. Kool
European Journal of Operational Research,
Nr. 1,
2009
Abstract
Bank efficiency estimates often serve as a proxy of managerial skill since they quantify sub-optimal production choices. But such deviations can also be due to omitted systematic differences among banks. In this study, we examine the effects of heterogeneity on bank efficiency scores. We compare different specifications of a stochastic cost and alternative profit frontier model with a baseline specification. After conducting a specification test, we discuss heterogeneity effects on efficiency levels, ranks and the tails of the efficiency distribution. We find that heterogeneity controls influence both banks’ optimal costs and profits and their ability to be efficient. Differences in efficiency scores are important for more than only methodological reasons. First, different ways of accounting for heterogeneity result in estimates of foregone profits and additional costs that are significantly different from what we infer from our general specification. Second, banks are significantly re-ranked when their efficiency is estimated with a specification other than the preferred, general specification. Third, the general specification gives the most reliable estimates of the probability of distress, although differences to the other specifications are low.

The Changing Role of the Exchange Rate in a Globalised Economy
Irina Bunda, Filippo di Mauro, Rasmus Rüffer
ECB Occasional Paper Series,
Nr. 94,
2008
Abstract
In addition to its direct effects on the global trading and production structure, the ongoing process of globalisation may have important implications for the interaction of exchange rates and the overall economy. This paper presents evidence regarding possible changes in the role of exchange rates in a more globalised economy. First, it analyses the link between exchange rates and prices, showing that there is at most a moderate decline in exchange rate pass-through for the euro area. Next, it turns to the effect of exchange rate changes on trade flows. The findings indicate that the responsiveness of euro area exports to exchange rate changes may have declined somewhat as a result of globalisation, reflecting mainly shifts in the geographical and sectoral composition of trade flows. The paper also provides a firm-level analysis of the impact of exchange rate changes on corporate profits, which suggests that overall this relationship appears to be relatively stable over time, although there are important cross-country differences. In addition, it studies the overall impact of exchange rates on GDP and the potential role of valuation effects as a transmission channel in the case of the euro area.

An Assessment of Bank Merger Success in Germany
Michael Koetter
German Economic Review,
Nr. 2,
2008
Abstract
German banks have experienced a merger wave since the early 1990s. However, the success of bank mergers remains a continuous matter of debate.This paper suggests a taxonomy to evaluate post-merger performance on the basis of cost and profit efficiency (CE and PE). I identify successful mergers as those that fulfill simultaneously two criteria. First, merged institutes must exhibit efficiency levels above the average of non-merging banks. Second, banks must exhibit efficiency changes between merger and evaluation year above efficiency changes of non-merging banks. I assess the post-merger performance up to 11 years after the mergers and relate it to the transfer of skills, the adequacy to merge distressed banks and the role of geographical distance. Roughly every second merger is a success in terms of either CE or PE. The margin of success in terms of CE is narrow, as efficiency differentials between merging and non-merging banks are around 1 and 2 percentage points. PE performance is slightly larger. More importantly, mergers boost in particular the change in PE, thus indicating persistent improvements of merging banks to improve the ability to generate profits.

The Stability of Bank Efficiency Rankings when Risk Preferences and Objectives are Different
Michael Koetter
European Journal of Finance,
Nr. 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.

International Banking and the Allocation of Risk
Claudia M. Buch
IAW Discussion Paper No. 32,
2007
Abstract
Macroeconomic risks could magnify individual bank risk. Mitigating the influence of economy-wide risks on banks could therefore be very important to maintain a smooth-running banking system. In this paper, we explore the extent to which macroeconomic risks affect banks. We use a bank-level dataset on over 2,000 banks worldwide for the years 1995-2002 to study the effect of macroeconomic volatility, the openness of the banking system, and banking regulations on bank risks. Our measure of bank risk is the volatility of banks' pre-tax profits. We find that macroeconomic volatility increases banks' profit volatility and that international openness of the banking system lowers bank risk. We find no impact of banking regulation on profit volatility. Our findings suggest that if policymakers want to lower bank risk, they should seek to lower macroeconomic volatility as well as increase openness in the banking system.

Local Public Utilities' Profits and Municipal Expenses in Germany: An Empirical Analysis
Peter Haug, Birger Nerré
Proceedings of the 99th Annual Conference on Taxation (November 16-18), Washington DC,
2006
Abstract
The article offers information on profits and municipal expenses of local public utilities in Germany. It reveals that cities and municipalities faced rising expenses over the last years and the only way for local governments to avoid budgetary bottlenecks is to postpone infrastructure investment and increase short-term borrowing. The countries municipalities tried to overcome such difficulties by increasing local public utilities' profits.
