Risk Management and Firm Value: Evidence from Weather Derivatives

This paper shows that active risk management policies lead to an increase in firm value. To identify the effect of hedging and to overcome endogeneity concerns, we exploit the introduction of weather derivatives as an exogenous shock to firms’ ability to hedge weather risks. This innovation disproportionately benefits weather‐sensitive firms, irrespective of their future investment opportunities. Using this natural experiment and data from energy firms, we find that derivatives lead to higher valuations, investments, and leverage. Overall, our results demonstrate that risk management has real consequences on firm outcomes.     

Engineering robust instruments for GMM estimation of panel data regression models with errors in variables: a note

Econometricians have long recognized the need to account in some way for measurement errors, specification errors and endogeneity to ensure that the ordinary least squares estimator is consistent. This article introduces a new generalized method of moments estimator that relies on robust instruments to estimate panel data regression models containing errors in variables. We show how this GMM approach can be generalized for the panel data framework using higher moments and cumulants as instruments. The new instruments, engineered for greater robustness, are proposed to tackle the pervasive problem of weak instruments.     

Consumer scapegoating during a systemic product-harm crisis

Abstract

To determine how consumers respond to betrayal of their trust in brands, we surveyed 2156 consumers in nine metropolitan centres in China following the 2008 melamine contamination crisis. Drawing on psychological drivers of scapegoating and attribution theory, we investigate how early information and the perceived involvement in a multi-brand crisis and attribution factors influence scapegoat effects. The survey results reveal that the first accused brand, Sanlu, took disproportionate blame and was made a scapegoat for an industry-wide crisis. The observer/tension-discharging perspective, the ‘early information’ effect, and the contrasting roles of manufacturers and non-manufacturer parties in the supply chain in causal attributions have the most significant effect in consumer scapegoating. Study of a highly unfortunate ‘real-life experiment’ shows how a food safety scandal spills over and negatively affects attitudes and beliefs about the whole supply chain and about competing brands.     

Antitrust Update: DG Competition 2007–2008

This article discusses some significant developments in the enforcement activities of the Directorate General for Competition at the European Commission, during 2007–2008, focusing on two main themes: non-horizontal mergers and two-sided markets.     

Media Plurality: Private versus Mixed Duopolies

In this paper, we analyze the level of media plurality in a market with two private news firms (private duopoly) and in a market with a private news firm and a public news firm (mixed duopoly). In the private duopoly news firms maximize profits. In the mixed duopoly, the private news firm maximizes profits, while the public news firm maximizes social welfare. We show that, in spite of the public news firm maximizing social welfare, neither media plurality nor social welfare needs to be higher under the mixed duopoly compared with the private duopoly. This will depend on the relation between the costs of adapting news to readers' political preferences, the intensity of the readers' political preferences, and the size of the advertising market.     

The e-integration dilemma: The linkages between Internet technology application, trading partner relationships and structural change

The evidence from an empirical study involving 281 Australian organizations suggests that the availability, open nature, and (comparative) ease of implementation of Internet technologies for integration with trading partners, whilst on the one hand providing the means by which organizations can integrate processes and systems in a cost effective way, can amplify the need for both structural change and closer collaboration with trading partners. The relationships proposed and tested in the model are justified and explained based on a number of theoretical perspectives. These include Transaction Cost Economics, Socio-technical Systems, Resource Dependency, Knowledge Based View, Stakeholder Theory and Organizational Learning. The implications of the findings for Transaction Cost Theory are noteworthy firstly because they support the appropriateness of the inter-organizational governance structure in the context of this study, and secondly because although application of these technologies may reduce information search and related costs, whether this necessarily leads to reduced coordination costs is problematic. The potential benefits from improved coordination may be constrained by the perceived costs, and risks, of transition to new structural forms. The implication for practice is that increased use of Internet technologies creates substantial pressure to invest in organizational change. The attractiveness of investing in technologies that place managers in a position where they need to promote organizational change in order to extract adequate returns creates a significant dilemma. On the one hand Internet technologies enable extensive sharing and integration of data among trading partners, but at the same time they create conditions requiring managers to embrace fundamental organizational change in order to leverage the potential of such integration.     

Option pricing with orthogonal polynomial expansions

We derive analytic series representations for European option prices in polynomial stochastic volatility models. This includes the Jacobi, Heston, Stein–Stein, and Hull–White models, for which we provide numerical case studies. We find that our polynomial option price series expansion performs as efficiently and accurately as the Fourier‐transform‐based method in the nested affine cases. We also derive and numerically validate series representations for option Greeks. We depict an extension of our approach to exotic options whose payoffs depend on a finite number of prices.     

Negative Monetary Policy Rates and Systemic Banks' Risk-Taking: Evidence from the Euro Area Securities Register

We show that negative monetary policy rates induce systemic banks to reach-for-yield. For identification, we exploit the introduction of negative deposit rates by the European Central Bank in June 2014 and a novel securities register for the 26 largest euro area banking groups. Banks with more customer deposits are negatively affected by negative rates, as they do not pass negative rates to retail customers, in turn investing more in securities, especially in those yielding higher returns. Effects are stronger for less capitalized banks, private-sector (financial and nonfinancial) securities and dollar-denominated securities. Affected banks also take higher risk in loans.
