Idiosyncratic risk and the cost of capital: the case of electricity networks

We analyze the treatment and impact of idiosyncratic or firm-specific risk in regulation. Regulatory authorities regularly ignore firm-specific characteristics, such as size or asset ages, implying different risk exposure in incentive regulation. In contrast, it is common to apply only a single benchmark, the weighted average cost of capital, uniformly to all firms. This will lead to implicit discrimination. We combine models of firm-specific risk, liquidity management and regulatory rate setting to investigate impacts on capital costs. We focus on the example of the impact of component failures for electricity network operators. In a simulation model for Germany, we find that capital costs increase by \(\sim \) 0.2 to 3.0 % points depending on the size of the firm (in the range of 3–40 % of total cost of capital). Regulation of monopolistic bottlenecks should take these risks into account to avoid implicit discrimination.     

Deutsche Leistungsbilanzüberschüsse in der Kritik

Germany runs large current account surpluses. Recently the surplus has been higher than seven per cent of GDP. This has provoked many different criticisms. First, some argue that the euro is the main problem. Second, German wages and prices have been criticised for being too low. Third, according to some critics, German domestic demand should be higher. Fourth, current account surpluses have been assumed to be unsustainable. The article discusses all those arguments and analyses their validity.     

Aiding Decision Making to Reduce the Impacts of Climate Change

Utilizing theory and empirical insights from psychology and behavioural economics, this paper examines individuals’ cognitive and motivational barriers to adopting climate change adaptation and mitigation measures that increase consumer welfare. We explore various strategies that take into account the simplified decision-making processes used by individuals and resulting biases. We make these points by working through two examples: (1) investments in energy efficiency products and new technology and (2) adaptation measures to reduce property damage from future floods and hurricanes. In both cases there is a reluctance to undertake these measures due to high and certain upfront costs, delayed and probabilistic benefits, and behavioural biases related to this asymmetry. The use of choice architecture through framing and the use of default options coupled with short-term incentives and long-term contracts can encourage greater investment in these measures.     

Recovery rates of commercial lending: Empirical evidence for German companies

There are very few studies concerning the recovery rate of bank loans. Prediction models of recovery rates are increasing in importance because of the Basel II-framework, the impact on credit risk management, and the calculation of loan rates. In this study, we focus the analyses on the distribution of recovery rates and the impact of the quota of collateral, the creditworthiness of the borrower, the size of the company and the intensity of the client relationship on the recovery rate. All our hypotheses can be confirmed. A higher quota of collateral leads to a higher recovery rate, whereas the risk premium of the borrower and the size of the company is negatively related to the recovery rate. Borrowers with an intense client relationship with the bank exhibit a higher recovery rate.     

The Impact of Direct Cash Payments on Whole Blood Supply

This paper investigates the impact of monetary incentives on whole blood donations. We take advantage of a quasi‐natural experiment in Germany, in which one blood donation site changes its payment scheme from remunerated to non‐remunerated. All other donation sites maintain their payment schemes. We show that donation volumes drop significantly after the pay drop and do not recuperate. At the same time, donation volumes increase at other paid donation sites, which is partly due to donor migration to these sites. We do not find any impact of the changed payment scheme on blood quality. Our results offer additional insight into the complex question whether it is efficient to ensure blood supply by paying donors a direct monetary compensation.     

Auctions versus bookbuilding: The effects of IPO regulation in Japan

We analyze a regulatory change in the Japanese IPO market that created an abrupt shift from hybrid price-discriminatory auctions to bookbuilding. We find that bookbuilding leads to higher underpricing than hybrid price-discriminatory auctions. Furthermore, we find evidence that price accuracy tends to be higher for auctions than for bookbuilding. The results hold under a variety of OLS specifications and with regression discontinuity designs exploiting the abrupt change of the regulation.     

Capital requirements and claims recovery: A new perspective on solvency regulation

Protection of creditors is a key objective of financial regulation. Where the protection needs are high, that is, in banking and insurance, regulatory solvency requirements are an instrument to prevent that creditors incur losses on their claims. The current regulatory requirements based on value at risk (V@R) and average value at risk (AV@R) limit the probability of default of financial institutions, but they fail to control the size of recovery on creditors' claims in the case of default. We resolve this failure by developing a novel risk measure, recovery V@R. Our conceptual approach is flexible and allows the construction of general recovery risk measures for various risk management purposes. We provide detailed case studies and applications. We show that recovery risk measures can be used for performance-based management of business divisions of firms and discuss how to calibrate recovery risk measures to historical regulatory standards. Finally, we analyze how recovery risk measures react to the joint distributions of assets and liabilities on firms' balance sheets and compare the corresponding capital requirements with the current regulatory benchmarks based on V@R and AV@R.
