Forecasting the CO2 certificate price risk
Henry Dannenberg, Wilfried Ehrenfeld
IWH Discussion Papers,
No. 5,
2008
Abstract
Modeling the price risk of CO2 certificates is one important aspect of integral corporate risk management related to emissions trading. The paper presents a risk model which may be the basis for evaluating the risk of emission certificate prices. We assume that the certificate price is determined by the expected marginal CO2 abatement costs prevailing at the current trade period and stochastically fluctuates around the respective level as returned from the mean reversion process. Due to uncertainties about future environmental states we suppose that within one trade period, erratic changes in the expected marginal abatement costs may occur leading to shifts in the price level. The aim of the work is to model the erratic changes of the expected reversion level and to estimate the parameters of the mean reversion process.

Oil Prices and International Trade: How Petrodollar Recycling Affects the Industrialised Countries
Götz Zeddies
Wirtschaft im Wandel,
No. 4,
2008
Abstract
Since 2004, prices for crude oil nearly tripled at international commodity markets. In the wake of the oil crises of the 1970s and ‘80s, numerous empirical studies analysing the macroeconomic effects of sharp increases in commodity prices were carried out pointing at the risks of oil price rises for GDP growth in oil-importing countries. However, in most of these analyses, the impact of oil price increases on international trade of oil-importing countries, which gained in importance in the course of globalisation, is considered only marginally. This is especially the case for the additional revenues of oil-exporting countries spent in large parts for imports from and investment in the industrialised economies.
The present article examines the impact of oil price increases on merchandise exports and imports of single oil-importing industrialised countries. The results show that the curbing effects on merchandise exports are lower than on imports. Whereas import demand responds disproportionally high on the decline in consumption and investment in consequence of oil price increases, the effects on merchandise exports are ambivalent. On the one hand, exports to oil-importing trading partner countries decline due to the local economic downturns, but on the other, exports to oil-exporting countries sharply increase. As a consequence, the negative impact of rising oil prices on macroeconomic activity in oil-importing countries is lowered by the external sector due to growing net exports.

Do Weak Supervisory Systems Encourage Bank Risk-taking?
Claudia M. Buch, G. DeLong
Journal of Financial Stability,
2008
Abstract
Weak bank supervision could give banks the ability to shift risk from themselves to supervisors. We use cross-border bank mergers as a natural experiment to test changes in risk and the impact of supervision. We examine cross-border bank mergers and find that the supervisory structures of the partners’ countries influence changes in post-merger total risk. An acquirer from a country with strong supervision lowers total risk after a cross-border merger. However, total risk increases when the target bank is located in a country with relatively strong supervision. This result is consistent with strong host regulators limiting the risky activities of their local banks. Foreign-owned competitors could then engage in the risky projects, especially if the foreign banks’ supervisors are not strong. An acquirer entering a country with strong supervision appears to shift risk back to its home country. The results suggest that bank supervisors can reduce total banking risk in their countries by being strong.

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.

The Maximum Level of Fines Restricts the Effect of European Competition Law
Henry Dannenberg, Nicole Steinat
Wirtschaft im Wandel,
No. 2,
2008
Abstract
In 2006, the fining guidelines for competition law infringements were completely renewed. The aim of this reform was twofold: on the one hand to decrease the incentive for cartelization and on the other hand to increase the likelihood of cartel detection.
The article studies how company’s decision for or against a cartel is influenced by these guidelines. We show that due to the maximum level of fines – which refers to the worldwide group turnover - an effective deterrence level can be achieved only for those companies, which realize just a small part of their turnover in the relevant market. Their incentive to blow the whistle increases with the cartel duration. This leads to a rising instability of cartels where one member generates only a small part of its turnover in the relevant market. In contrast, the deterrence level for companies that realize a large part of their sales in the relevant market is quite low due to the maximum level of fines.
The article gives a short overview of the risk factor competition law – from a company perspective. We illustrate how the expenditures related to cartel law infringements can be calculated. Further on, the minimum profit margins that are necessary for an economically advantageous cartel are determined. We show that for certain types of cartels already small rates of return are sufficient to make cartel participation attractive.

Risk-factor competition law infringement
Henry Dannenberg, Nicole Steinat
Risk, Fraud & Compliance ZRFC,
No. 1,
2008
Abstract
During the last couple of years the European Commission increased the fines for competition law infringements. Regardless whether an infringement was only negligent or intended it can result in enormous financial risks for companies. The following article shows a distribution of the financial risk of cartel law infringements in Europe. The potential fine - which can amount to a multiple of annual sales in the relevant market - should sensitize managers to check their own undertaking whether they are involved in such violations.

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.

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.

Three methods of forecasting currency crises: Which made the run in signaling the South African currency crisis of June 2006?
Tobias Knedlik, Rolf Scheufele
IWH Discussion Papers,
No. 17,
2007
Abstract
In this paper we test the ability of three of the most popular methods to forecast the South African currency crisis of June 2006. In particular we are interested in the out-ofsample performance of these methods. Thus, we choose the latest crisis to conduct an out-of-sample experiment. In sum, the signals approach was not able to forecast the outof- sample crisis of correctly; the probit approach was able to predict the crisis but just with models, that were based on raw data. Employing a Markov-regime-switching approach also allows to predict the out-of-sample crisis. The answer to the question of which method made the run in forecasting the June 2006 currency crisis is: the Markovswitching approach, since it called most of the pre-crisis periods correctly. However, the “victory” is not straightforward. In-sample, the probit models perform remarkably well and it is also able to detect, at least to some extent, out-of-sample currency crises before their occurrence. It can, therefore, not be recommended to focus on one approach only when evaluating the risk for currency crises.

For a Sustainable Contribution Rate of the Statutory Unemployment Insurance
Ingmar Kumpmann
Wirtschaft im Wandel,
No. 11,
2007
Abstract
The German Federal Government has decided to decrease the contribution rate of the statutory unemployment insurance from 4.2 to 3.3 per cent of gross wages. The unemployment insurance retards the income loss in times of increasing unemployment, which has a dampening effect on the business cycle. In order not to countervail this effect it is necessary to hold the contribution rate stable over times with high and low unemployment. Therefore, the budget surplus of the unemployment insurance agency in the current economic upswing is no sufficient argument for a contribution cut. A present reduction of the contribution rate induces the risk of a new contribution rise in the next economic slowdown. It would be better to build up sufficient reserves so that a contribution rise will be avoidable even in times with increasing unemployment.
