Integrated models of capital adequacy – Why banks are undercapitalised

With the majority of large UK and many US banks collapsing or being forced to raise capital over the 2007–9 period, blaming bankers may be satisfying but is patently insufficient; Basel II and Federal oversight frameworks also deserve criticism. We propose that the current methodological void at the heart of Basel II, Pillar 2 is filled with the recommendation that banks develop fully-integrated models for economic capital that relate asset values to fundamental drivers of risk in the economy to capture systematic effects and inter-asset dependencies in a way that crude correlation assumptions do not. We implement a fully-integrated risk analysis based on the balance sheet of a composite European bank using an economic-scenario generation model calibrated to conditions at the end of 2007. Our results suggest that the more modular, correlation-based approaches to economic capital that currently dominate practice could have led to an undercapitalisation of banks, a result that is clearly of interest given subsequent events. The introduction of integrated economic-scenario-based models in future can improve capital adequacy, enhance Pillar 2’s application and rejuvenate the relevance of the Basel regulatory framework.     

Firm wage differentiation in Eastern GermanyA non-parametric analysis of the wage spread

In Eastern Germany, wage differentiation between firms has clearly grown, parallel to individual wage differentials. Nevertheless, the wage spread between firms is still much less than in Western Germany. In this paper, a non‐parametric decomposition is used to analyze the difference between the wages spread in the two parts of Germany. Only part of the difference can be explained by different economic structures in Eastern Germany. By far, the greater part of the difference in the wage spread between firms in the two parts of the country is due to the fact that differences in wages paid by firms of the same type in Eastern Germany are much less than those of their counterparts in Western Germany. A striking result of the analysis is that the gap in the wage variance between Eastern and Western Germany is increasing.     

THE EFFECTS OF PRESENTATION FORMAT ON THE EFFECTIVENESS AND EFFICIENCY OF AUDITORS‘ ANALYTICAL REVIEW JUDGMENTS

Modern audit practice has focused increasing attention on the use of analytical review procedures to improve the effectiveness and efficiency of audits. To assist in this endeavour, one branch of analytical review research has investigated the judgment processes that auditors' use in analytical review and the development of decision aids to improve these processes. Several recent papers have considered how alternative presentations of financial and operating data, specifically graphs versus tables, may affect the effectiveness of auditors' analytical review judgments. However, the results have been mixed. This study investigated the expectation that there would be effectiveness and efficiency performance advantages for auditors receiving graphically presented data over those receiving tabular presented data in an analytical review setting. This paper reports on the results of an experiment that examined the impact of graphs versus tables on the effectiveness of sales account balance prediction, confidence in this prediction and the setting of a noninvestigation region, and the relative time efficiency with which these tasks were completed, for an analytical review of sales for a retailing client. The study found mixed results for the accuracy of the sales account balance predictions of the graphical and tabular treatment groups, with no difference found when a regression model estimate of the ‘correct’ prediction was used and greater accuracy for the graphical group when the actual audited sales account balance was used as the accuracy benchmark. No significant differences between treatment groups was found for their confidence in their sales account balance predictions and the width of the noninvestigation regions set. However, a significant time advantage was found for the graphical group. These findings suggest that there may a useful role for the use of graphs as decision aids in income statement related analytical review procedures in improving audit efficiency without sacrificing audit effectiveness.     

Foreign investment as a factor in Asian Pacific integration

The Asian Pacific countries do not only show unparalled growth dynamics, they are also in the process of growing ever closer together. There is already talk of the creation of a new economic bloc. The following article analyses private direct investment in the Asian Pacific area, an element in the economic integration of the region which has been paid little attention until now. This article is based on a study completed in November 1991 for the Federal Ministry of Economic Affairs. The study has now been published in German and is available on request from the authors: Axel Borrmann and Rolf Jungnickel: Auslandsinvestitionen im asiatisch-pazifischen Integrationsprozess, HWWA-Report No. 102, Hamburg 1992.     

What to do if a dollar is not a dollar? The impact of inflation risk on production and risk management

An entrepreneur faces two types of risk: one from income generation, one from income spending. His income from firm profits is risky due to output price fluctuations and other risks. As a consumer, he is also exposed to inflation risk since he maximizes expected utility of real income. This article focuses on optimal production and risk management decisions of a risk‐averse entrepreneur jointly facing tradable output price risk and untradable inflation risk. Inflation risk applies multiplicatively to the entrepreneur's entire nominal income. Relative risk aversion and the risks' joint distribution determine the effect of introducing a futures market on production. For dependent risks, this effect may be negative if relative risk aversion is above one. Relative risk aversion and the joint distribution also determine optimal risk management with futures contracts where speculation on a real risk premium and cross hedging may be conflicting objectives. © 2002 Wiley Periodicals, Inc.

Hybrid Choice Models: Progress and Challenges

We discuss the development of predictive choice models that go beyond the random utility model in its narrowest formulation. Such approaches incorporate several elements of cognitive process that have been identified as important to the choice process, including strong dependence on history and context, perception formation, and latent constraints. A flexible and practical hybrid choice model is presented that integrates many types of discrete choice modeling methods, draws on different types of data, and allows for flexible disturbances and explicit modeling of latent psychological explanatory variables, heterogeneity, and latent segmentation. Both progress and challenges related to the development of the hybrid choice model are presented.     

The transmission of bank capital requirements and monetary policy to bank lending in Germany

We investigate the transmission of changes in bank capital requirements and monetary policy, and their interaction, on German banks’ corporate loan growth and lending rates. Our results show that increases in capital requirements are associated with an immediate decrease in total domestic and cross‐border bank lending. Changes in the euro area's monetary policy stance are positively related to corporate loan interest rates in general. Regarding the interacting effect of national bank capital requirements and euro area monetary policy, we observe that the transmission of accommodative euro area monetary policy to corporate lending rates can be attenuated by contemporaneous increases in bank capital requirements. Moreover, more strongly capitalized banks increase their loan growth in response to accommodative monetary policy whereas, for weaker banks, increasing capital requirements implies a decrease in their corporate loan growth. Our results confirm a tradeoff between higher capital requirements and accommodating monetary policy originating from banks’ capital constraints.     

Determinants of Anti‐Trafficking Policies: Evidence from a New Index

We develop an index measuring the three main dimensions – prosecution, protection, and prevention – of the anti‐trafficking policies of the governments of up to 180 countries over the 2000?2010 period. Overall, developed countries perform better than the rest of the world; compliance with prosecution policy is highest, while governmental efforts to protect victims of human trafficking remain weakest. We employ the new indices to investigate which factors determine anti‐trafficking policies. We find that compliance with anti‐trafficking policies significantly decreases with corruption and is higher in countries that also respect the rights of women. We also find some tentative evidence for spatial dependence in anti‐trafficking policies.
