On the Economic Architecture of the Workplace: Repercussions of Social Comparisons among Heterogeneous Workers
Oded Stark, Walter Hyll
Journal of Labor Economics,
No. 2,
2011
Abstract
We analyze the impact on a firm’s profits and optimal wage rates, and on the distribution of workers’ earnings, when workers compare their earnings with those of co-workers. We consider a low-productivity worker who receives lower wage earnings than a high-productivity worker. When the low-productivity worker derives (dis)utility not only from his own effort but also from comparing his earnings with those of the high-productivity worker, his response to the sensing of relative deprivation is to increase the optimal level of effort. Consequently, the firm’s profits are higher, its wage rates remain unchanged, and the distribution of earnings is compressed.

Stochastic Income Statement Planning as a Basis for Risk Assessment in the Context of Emissions Trading
Henry Dannenberg, Wilfried Ehrenfeld
Greenhouse Gas Measurement and Management,
No. 1,
2011
Abstract
The introduction of the European emissions trading system means that those enterprises taking part have a new planning risk factor to consider – emissions allowance prices. In this article, we analyse how risk emerging from emissions trading can be considered in the stochastic income statement planning of corporations. Therefore, we explore which planned figures are affected by emissions trading. Moreover, we show an approach that models these positions in a planned profit and loss account, taking into account uncertainties and dependencies. Consequently, this model provides a basis for risk assessment and investment decisions in the uncertain environment of emissions trading.

Handling Losses in Translog Profit Models
J. W. B. Bos, Michael Koetter
Applied Economics,
No. 3,
2011
Abstract
In this article, we compare standard approaches used to handle losses in logarithmic profit models with a simple novel approach. We estimate translog stochastic profit frontiers, and discuss discriminatory power, rank stability and the precision of Profit Efficiency (PE) scores. Contrary to existing methods, our approach does not result in a loss of observations. Our new method enhances rank stability and discriminatory power, and improves the precision of PE scores.

Differences in Labor Supply to Monopsonistic Firms and the Gender Pay Gap: An Empirical Analysis Using Linked Employer‐Employee Data from Germany
Boris Hirsch, Thorsten Schank, Claus Schnabel
Journal of Labor Economics,
No. 2,
2010
Abstract
This article investigates women’s and men’s labor supply to the firm within a semistructural approach based on a dynamic model of new monopsony. Using methods of survival analysis and a large linked employer‐employee data set for Germany, we find that labor supply elasticities are small (1.9–3.7) and that women’s labor supply to the firm is less elastic than men’s (which is the reverse of gender differences in labor supply usually found at the level of the market). Our results imply that at least one‐third of the gender pay gap might be wage discrimination by profit‐maximizing monopsonistic employers.

A New Metric for Banking Integration in Europe
Reint E. Gropp, A. K. Kashyap
Europe and the Euro,
2010
Abstract
Most observers have concluded that while money markets and government bond markets are rapidly integrating following the introduction of the common currency in the euro area, there is little evidence that a similar integration process is taking place for retail banking. Data on cross-border retail bank flows, cross-border bank mergers and the law of one price reveal no evidence of integration in retail banking. This paper shows that the previous tests of bank integration are weak in that they are not based on an equilibrium concept and are neither necessary nor sufficient statistics for bank integration. The paper proposes a new test of integration based on convergence in banks' profitability. The new test emphasises the role of an active market for corporate control and of competition in banking integration. European listed banks profitability appears to converge to a common level. There is weak evidence that competition eliminates high profits for these banks, and underperforming banks tend to show improved profitability. Unlisted European banks differ markedly. Their profits show no tendency to revert to a common target rate of profitability. Overall, the banking market in Europe appears far from being integrated. In contrast, in the U.S. both listed and unlisted commercial banks profits converge to the same target, and high profit banks see their profits driven down quickly.

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,
No. 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.

The Spatial Clustering of the Photo-voltaic Industry in Berlin-Brandenburg
Steffen Ebert, Matthias Brachert, Iciar Dominguez Lacasa
Wirtschaft im Wandel,
No. 11,
2009
Abstract
Recent empirical studies show a process of selective clustering in the photo-voltaic industry in East Germany. Especially locations like Bitterfeld-Wolfen, Freiberg/Dresden, Erfurt/Arnstadt and Berlin-Brandenburg were able to attract concentrations of economic activity in this industry. Regarding competition between the different locations for production and employment, emerging agglomeration economies can be seen as one major source increasing inter-regional competitiveness.
The aim of this article is to provide insights into the process of spatial clustering of photo-voltaic industry in Berlin-Brandenburg. With the help of a multi-dimensional cluster-concept developed by Bathelt, we analyse the region’s strengths and weaknesses regarding its generation of agglomeration economies.
The analysis shows that there are indeed first signs of agglomeration economies developing in the region. Despite a low level of horizontal cooperation, companies do profit from co-localisation by continuous observation of the local competitors. Along the value adding production chain, vertical co-operation is increasing, leading to positive effects by specialised suppliers and gains in transportation cost.
But the focal point in further industry development is the augmentation of the regional stock of knowledge. Regarding the increasing pressure on the companies’ innovativeness as a result of changes in market conditions in the photo-voltaic sector, only innovative and efficiently producing companies will be able to survive the industries’ consolidation period. Therefore, it is necessary to further support the increasing interconnectedness between university research, non-university research and local companies in order to profit from the high technological potential of the companies in the region.

Monopolistic Competition and Costs in the Health Care Sector
Ingmar Kumpmann
IWH Discussion Papers,
No. 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.

The Identification of Technology Regimes in Banking: Implications for the Market Power-Fragility Nexus
Michael Koetter, Tigran Poghosyan
Journal of Banking and Finance,
No. 8,
2009
Abstract
Neglecting the existence of different technologies in banking can contaminate efficiency, market power, and other performance measures. By simultaneously estimating (i) technology regimes conditional on exogenous factors, (ii) efficiency conditional on risk management, and (iii) Lerner indices of German banks, we identify three distinct technology regimes: Public & Retail, Small & Specialized, and Universal & Relationship. System estimation at the regional level reveals that greater bank market power increases bank profitability but also fosters corporate defaults. Corporate defaults, in turn, lead to higher probabilities of bank distress, which supports the market power-fragility hypothesis.
