Are there always synergies between productive resources and resource deployment capabilities?

While the independent impacts of particular firm resources and deployment capabilities on firm performance are unambiguous cornerstones of the strategy field, it is commonly assumed that their joint impacts are synergistic. This article seeks to understand whether this common misconception of resource‐based theory can be refuted empirically. Using data from hospitals conducting specialist surgery, I find hospital performance improves independently through better surgical resource quality and from more use of a streamlined form of resource management in which overall patient team leadership and operating team leadership are held by the same physician. Generally the interaction of these two firm activities had no impact on performance. These results contribute to the strategy field's understanding of whether and when internal fit affects performance, clarifying an incorrect inference commonly made about resource‐based theory.

FIRM HETEROGENEITY,IMITATION, AND THE INCENTIVES FOR COST REDUCING R&D EFFORT*

I develop and test a model of strategic R&D investments where innovating and non‐innovating firms compete on the basis of their ability to reduce costs and imitate rivals. I find that a larger proportion of non‐innovating rivals stimulates cost‐reducing investments and attenuates the disincentive effect of imitation by innovators on firm level R&D. Key model properties are verified by estimating the first order condition for the optimal choice of R&D, using the 1994 Carnegie Mellon survey of U.S. industrial R&D. Results also suggest that R&D and size are simultaneously determined, with R&D being proportional to size, as predicted by the theoretical model.     

Econophysics review: II. Agent-based models

This article is the second part of a review of recent empirical and theoretical developments usually grouped under the heading Econophysics. In the first part, we reviewed the statistical properties of financial time series, the statistics exhibited in order books and discussed some studies of correlations of asset prices and returns. This second part deals with models in Econophysics from the point of view of agent-based modeling. Of the large number of multi-agent-based models, we have identified three representative areas. First, using previous work originally presented in the fields of behavioral finance and market microstructure theory, econophysicists have developed agent-based models of order-driven markets that we discuss extensively here. Second, kinetic theory models designed to explain certain empirical facts concerning wealth distribution are reviewed. Third, we briefly summarize game theory models by reviewing the now classic minority game and related problems.     

Which Factors Affect Bond Underwriting Fees? The Role of Banking Relationships

The question of which factors are relevant in determining bond underwriting fees is empirically investigated by analysing 2,202 bond issues completed by European firms during the 1993 – 2003 period. Four major results emerge from the analysis. First, the introduction of the single currency in 1999 has generated an increase in competition among banks, and, as a result, a reduction in underwriting fees. Second, a strong relationship with the issuer's main bank reduces the level of underwriting fees. Third, new issuers are charged with lower underwriter fees relative to firms that have completed issues without building any strong relationship with a bank. Fourth, higher reputation banks charge lower underwriting fees. The implications of these findings are also discussed.     

The dynamic of financial crises and its non-monotonic effects on earnings quality

Despite the wealth of research examining earnings quality and earnings management, we still have much to learn about the effects of macroeconomic factors on accounting discretion’s decisions; the recent financial crises may be one of such factors. Nevertheless, the extant literature is inconclusive about the direction of the relationship between earnings quality and economic downturn. In this study, we focus on the extent to which organizational survival may be an objective of earnings management. In this manner, we add to research considering earnings target as an objective of earnings manipulation. Furthermore, our results suggest that these objectives likely change as crisis becomes worse. Consequently, we argue that the relationship between financial crises and earnings management is non-monotonic. Earnings management decreases when the intensity of the crisis is low, while it increases when the crisis is acute.     

How (not) to pay for advice: A framework for consumer financial protection

This paper investigates the determinants of the compensation structure for brokers who advise customers regarding the suitability of financial products. Our model explains why brokers are commonly compensated indirectly through contingent commissions paid by product providers, even though this compensation structure could lead to biased advice. When customers are wary of the adviser's incentives, contingent commissions can be an effective incentive tool to induce the adviser to learn which specialized product is most suitable for the specific needs of customers. If, instead, customers naively believe they receive unbiased advice, high product prices and correspondingly high commissions become a tool of exploitation. Policy intervention that mandates disclosure of commissions can protect naive consumers and increase welfare. However, prohibiting or capping commissions could have the unintended consequence of stifling the adviser's incentive to acquire information. More vigorous competition benefits consumers and reduces exploitation, but firms have limited incentives to educate naive customers.     

An integrated approach to supply chain risk analysis

Despite the increasing attention that supply chain risk management is receiving by both researchers and practitioners, companies still lack a risk culture. Moreover, risk management approaches are either too general or require pieces of information not regularly recorded by organisations. This work develops a risk identification and analysis methodology that integrates widely adopted supply chain and risk management tools. In particular, process analysis is performed by means of the standard framework provided by the Supply Chain Operations Reference Model, the risk identification and analysis tasks are accomplished by applying the Risk Breakdown Structure and the Risk Breakdown Matrix, and the effects of risk occurrence on activities are assessed by indicators that are already measured by companies in order to monitor their performances. In such a way, the framework contributes to increase companies’ awareness and communication about risk, which are essential components of the management of modern supply chains. A base case has been developed by applying the proposed approach to a hypothetical manufacturing supply chain. An in-depth validation will be carried out to improve the methodology and further demonstrate its benefits and limitations. Future research will extend the framework to include the understanding of the multiple effects of risky events on different processes.     

Der EU Richtlinienvorschlag für erneuerbare Energien — Eine Analyse der Transferrestriktionen von Herkunftsnachweisen

Until now the promotion of renewable energies in Europe has been effected on the basis of different promotion systems of the Member States. Currently the EU-wide harmonisation of the promotion systems, from which yields of efficiency and a higher effectiveness are expected, cannot be enforced due to a discordance concerning the “right” promotion instrument.With the proposal for a directive on the promotion of renewable energies, published at the 23. January in 2008, the European Commission attempts to make a first move towards harmonisation. Besides existing promotion systems it will be possible to transfer Guarantees of Origin for renewable energies between Member States. Since, however, some Member States expect negative effects as a consequence of opening their markets the proposal comprises opportunities to restrict the transfer. The present scope of interpretation within the proposal allows for different options concerning the design of the transfer restrictions. These will be identified, analysed, and subsequently evaluated in this article. Despite of both extreme options, the possibility to entirely opt out of the transfer system and the obligation to completely participate in the transfer system, two further hybrid options are discussed. The latter are characterised by the possibility of Member States to restrict the transfer of Guarantees of Origin to a certain extent through a “system of prior authorisation”.     

Non-linear Gaussian sovereign CDS pricing models

Prior literature indicates that quadratic models and the Black–Karasinski model are very promising for CDS pricing. This paper extends these models and the Black [J. Finance 1995, 50, 1371–1376] model for pricing sovereign CDS’s. For all 10 sovereigns in the sample quadratic models best fit CDS spreads in-sample, and a four factor quadratic model can account for the joint effects on CDS spreads of default risk, default loss risk and liquidity risk with no restriction to factors correlation. Liquidity risk appears to affect sovereign CDS spreads. However, quadratic models tend to over-fit some CDS maturities at the expense of other maturities, while the BK model is particularly immune from this tendency. The Black model seems preferable because its out-of-sample performance in the time series dimension is the best.     

Jensen's alpha and the market‐timing puzzle

Theory predicts that market‐timing activities bias Jensen's alpha (JA). However, empirical studies have failed to find consistent evidence of this bias. We tackle this puzzle in a nested model analysis and show that the bias contains an exogenous market component that is unrelated to market‐timing skill. In a comprehensive empirical analysis of US mutual funds, we find that the timing‐induced bias in JA is mainly driven by this market component, which is uncorrelated with measured timing activities. Measures of total performance that allow for timing activities are virtually identical to JA, even if timing activities are present in the evaluated fund. Hence, we conclude that JA is a sufficient measure of total performance.
