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.

Measurement Matters — Alternative Input Price Proxies for Bank Efficiency Analyses
Michael Koetter
Journal of Financial Services Research,
Nr. 2,
2006
Abstract
Most bank efficiency studies that use stochastic frontier analysis (SFA) employ each bank’s own implicit input price when estimating efficient frontiers. But at the same time, most studies are based on cost and/or profit models that assume perfect input markets. Traditional input price proxies therefore contain at least substantial measurement error. We suggest here two alternative input market definitions to approximate exogenous input prices. We have access to Bundesbank data, which allows us to cover virtually all German universal banks between 1993 and 2003. The use of alternative input price proxies leads to mean cost efficiency that is significantly five percentage points lower compared to traditional input prices. Mean profit efficiency is hardly affected. Across models, small cooperative banks located in large western states perform best while large banks and those located in eastern states rank lowest.

Network Investment and the Threat of Regulation – Preventing Monopoly Exploitation or Infrastructure Construction?
Ulrich Blum, Christian Growitsch, Niels Krap
IWH Discussion Papers,
Nr. 7,
2006
Abstract
In summer 2005, the German telecommunication incumbent Deutsche Telekom announced its plans to build a new broadband fibre optics network. Deutsche Telekom decided as precondition for this new network not to be regulated with respect to pricing and third party access. To develop a regulator's strategy that allows investments and prevents monopolistic prices at the same time, we model an incumbent's decision problem under a threat of regulation in a game-theoretical context. The decision whether to invest or not depends on the probability of regulation and its assumed impact on investment returns. Depending on the incumbent's expectation on these parameters, he will decide if the investment is favourable, and which price to best set. This price is below a non-regulated profit maximising price, since the incumbent tries to circumvent regulation. Thus, we show that the mere threat of a regulator's intervention might prevent supernormal profits without actual price regulation. The regulator, on the other hand, can influence both investment decision and the incumbent's price via his signals on regulation probability and price. These signals an be considered optimal, if they simultaneously allow investment and minimize the incumbent's price.

A Game Theoretic Analysis of the Conditions of Knowledge Transfer by New Employees in Companies
Sidonia vonLedebur
IWH Discussion Papers,
Nr. 3,
2006
Abstract
The availability of knowledge is an essential factor for an economy in global competition. Companies realise innovations by creating and implementing new knowledge. Sources of innovative ideas are partners in the production network but also new employees coming from another company or academia. Based on a model by HECKATHORN (1996) the conditions of efficient knowledge transfer in a team are analysed. Offering knowledge to a colleague can not be controlled directly by the company due to information asymmetries. Thus the management has to provide incentives which motivate the employees to act in favour of the company by providing their knowledge to the rest of the team and likewise to learn from colleagues. The game theoretic analysis aims at investigating how to arrange these incentives efficiently. 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 a 2x2 game but is at least partly generalised on more players. The relevance of the adequate team size is shown: more developers may increase the total profit of an innovation
(before paying the involved people) but when additional wages are paid to each person a greater team decreases 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. These formal results are consistent with empirical studies to the absorptive capacity and the working atmosphere.

Softening Competition by Inducing Switching in Credit Markets
Jan Bouckaert, Hans Degryse
Journal of Industrial Economics,
Nr. 1,
2004
Abstract
We show that competing banks relax overall competition by inducing borrowers to switch lenders. We illustrate our findings in a two-period model with adverse selection where banks strategically commit to disclosing borrower information. By doing this, they invite rivals to poach their first-period market. Disclosure of borrower information increases the rival's second-period profits. This dampens competition for serving the first-period market.

Local Taxes and Capital Structure Choice
Reint E. Gropp
International Tax and Public Finance,
Nr. 1,
2002
Abstract
This paper investigates the question of taxation and capital structure choice in Germany. Germany represents an excellent case study for investigating the question of whether and to what extent taxes influence the debt-equity decision of firms, because the relative tax burdens on debt and equity vary greatly across communities. German communities levy local taxes on profits and long-term debt payments in addition to personal and corporate taxes on the federal level. A stylized model is presented incorporating these taxes. The model shows that local taxes create substantial incentives for firms to use debt financing. Furthermore, the paper empirically investigates the effect of local business taxes on the share of debt used to finance incremental investments by German firms. I find that local taxes significantly influence the capital structure choice of firms, controlling for a large number of other factors. In an extensive sensitivity analysis the tax effect are found to be robust across several different specifications.

Korean Unification and Banking System - An Analysis in View of German Experiences and Korean Differences
Ralf Müller
IWH Discussion Papers,
Nr. 139,
2001
Abstract
One of the reforms that have to be launched in a future unification process in Korea, which seems possible after the political negotiations last year, is the transformation of the North Korean banking system. The question arises whether Korea could profit from the German experience where banking transformation was one of the rather few success stories in unification. In 1990 the East German banking transformation was achieved relatively fast and uncomplicated due to considerable direct investments of the West German banks compounded with state guarantees for bad loans resulting from the credit business with existing GDR-corporations. Unfortunately, South Korea currently lacks some major prerequesites that contributed to the German banking unification, among them – and probably the most important one – is the lack of a sound and efficient banking
system that could become active in the North. Consequently, depending on the circumstances of a future Korean unification either a more gradual process is recommended or, if inner-Korean migration requires a more dynamic transition, considerable investment by foreign banks and assistance from international organisations is recommended.

Environmental policy under product differentiation and asymmetric costs - Does Leapfrogging occur and is it worth it?
Jacqueline Rothfels
IWH Discussion Papers,
Nr. 124,
2000
Abstract
This paper studies the influence of environmental policies on environmental quality, domestic firms, and welfare. Point of departure is Porter’s hypothesis that unilateral environmental regulation may enhance the competitiveness of domestic firms. This hypothesis has recently received considerable support in theoretical analyses, especially if imperfectly competitive markets with strategic behavior on behalf of the agents are taken into account. Our work contributes to this literature by explicitely investigating the implications of asymmetric cost structures between a domestic and a foreign firm sector. We use a partial-equilibrium model of vertical product differentiation, where the consumption of a product causes environmental harm. Allowing for differentiated products, the domestic industry can either assume the market leader position or lag behind in terms of the environmental quality of the produced product. Assuming as a benchmark case that the domestic industry lags behind, we investigate the possibility of the government to induce leapfrogging of the domestic firm, i.e. a higher quality produced by the domestic firm after regulation than that of the competitor prior to regulation. It is shown that in the case of a cost advantage for the domestic firm in the production process the imposition of a binding minimum quality standard can serve as a tool to induce leapfrogging. In case of a cost disadvantage the same result can be achieved through an adequate subsidization of quality dependend production costs. Thus, careful regulation enables the domestic firm in both scenarios to better its competitive position against foreign competitors and to earn larger profits. Additionally, environmental quality and welfare can be enhanced.
