An Empirical Examination of Institutional Investor Preferences for Corporate Social Performance

This study investigates the pattern of institutional shareholding in the U.K. and its relationship with socially responsible behavior by companies within a sample of over 500 UK companies. We estimate a set of ownership models that distinguish between long- and short-term investors and their largest components and which incorporate both aggregated and disaggregated measures of corporate social performance (CSP). The results suggest that long-term institutional investment is positively related to CSP providing further support for earlier studies by Johnson and Greening (1999, Academy of Management Journal 42, 564–576) and Graves and Waddock (1994, Academy of Management Journal 37, 1034–1046). Disaggregation of CSP into its constituent components suggests that the pattern of institutional investment is also related to the form which CSP takes. Investigation of the impact of investment screens on the selection of stocks suggests that long-term institutional investors select primarily through exclusion, rejecting those firms which have the worst CSP.     

Spatial allocation and the shadow pricing of product characteristics

The paper considers an industry transforming primary commodities (farm products) into processed commodities (food products). It focuses on the allocation of embedded characteristics (carbohydrate, protein, etc.) both across space and among commodities. The approach generates a spatial competitive market equilibrium of production, consumption, transformation, and trade for both primary and processed commodities, along with the spatial distribution of shadow prices for the product characteristics. The model provides a basis for analyzing the allocation and pricing of agricultural products, food products, and characteristics in spatial markets. The empirical usefulness of the model is illustrated in the context of regional resource allocation in the U.S. dairy sector.     

Best Practice Marketing for Regional Tourism Destinations

This article reports on destination marketing best practices from 21 regional destinations around Australia. The results advocate an integrative approach to destination marketing that aligns with destination management and development objectives. From this, a framework is developed, within which nine best practice principles are identified as essential to successful and sustainable marketing of regional destinations. The key initiatives used to achieve success are discussed in detail, highlighting the need for destination stakeholders to foster a cooperative and strategic approach and ensure consistent design and delivery of a destination brand and image which is supported by tactical advertising and promotional strategies, effective visitor information services, and events to support the destination brand and image to target appropriate visitor markets.     

On the Application of Conditional Independence to Ordinal Data

A special log linear parameterization is described for contingency tables which exploits prior knowledge that an ordinal scale of the variables is involved. It is helpful, in particular, in guiding the possible merging of adjacent levels of variables and may simplify interpretation if higher-order interactions are present. Several sets of data are discussed to illustrate the types of interpretation that can be achieved. The simple structure of the maximum likelihood estimates is derived by use of Lagrange multipliers.     

Robust pricing and hedging under trading restrictions and the emergence of local martingale models

We pursue the robust approach to pricing and hedging in which no probability measure is fixed, but call or put options with different maturities and strikes can be traded initially at their market prices. We allow the inclusion of robust modelling assumptions by specifying a set of feasible paths on which (super)hedging arguments are required to work. In a discrete-time setup with no short selling, we characterise absence of arbitrage and show that if call options are traded, then the usual pricing–hedging duality is preserved. In contrast, if only put options are traded, a duality gap may appear. Embedding the results into a continuous-time framework, we show that the duality gap may be interpreted as a financial bubble and link it to strict local martingales. This provides an intrinsic justification of strict local martingales as models for financial bubbles arising from a combination of trading restrictions and current market prices.     

Mortgage Insurance Adoption in the Netherlands

Individuals tend to underinsure on low probability, high consequence risks. Using a survey data set from a unique institutional context, we provide an assessment of the underinsurance puzzle by studying mortgage insurance adoption among Dutch homeowners. The results indicate that the demand for mortgage insurance is affected by risk exposure, type of mortgage lender, and the involvement of financial advisors. We document that wealthier and younger mortgagors are more likely to insure. However, locus of control, house price expectations, and precautionary savings are not related to insurance demand. Finally, we find evidence that borrower (over)confidence negatively affects the likelihood that insurance is bought.     

An Option-Based Operational Risk Management Model for Pandemics

Abstract

In this paper we employ the theory of real option pricing to address problems in the area of operational risk management. We develop a two-stage model to help firms determine the optimal suspension-reactivation triggers in the events of pandemics. In the first stage, we propose a regime-dependent epidemic model to simulate the spread of the virus, depending on whether the firm is active or inactive. In the second stage, we view the reactivation decision as a call option and the suspension decision as a put option, and use dynamic programming methods to obtain the optimal switching thresholds. Our method can be regarded as a quantitative implementation of the CDC’s instructions for pandemic preparation. We find that when they take the uncertainty of disease transmission into consideration, firms are more conservative about the decisions of suspension and reactivation. We also find that when firms incur switching costs, the suspension threshold increases with costs, whereas the reactivation threshold decreases with costs. By adopting disease control policies, firms can increase their values in both regimes.     

Mortality Regimes and Pricing

Abstract

Mortality dynamics are characterized by changes in mortality regimes. This paper describes a Markov regime-switching model that incorporates mortality state switches into mortality dynamics. Using the 1901-2005 U.S. population mortality data, we illustrate that regime-switching models can perform better than well-known models in the literature. Furthermore, we extend the 1992 Lee-Carter model in such a way that the time-series common risk factor to all cohorts has distinct mortality regimes with different means and volatilities. Finally, we show how to price mortality securities with this model.     

Application of Risk Theory to Interpretation of Stochastic Cash-Flow-Testing Results

Abstract

In this paper we consider the Sparre Andersen insurance risk model. Three cases are discussed: the ordinary renewal risk process, stationary renewal risk process, and s-delayed renewal risk process. In the first part of the paper we study the joint distribution of surplus immediately before and at ruin under the renewal insurance risk model. By constructing an exponential martingale, we obtain Lundberg-type upper bounds for the joint distribution. Consequently we obtain bounds for the distribution of the deficit at ruin and ruin probability. In the second part of the paper, we consider the special case of phase-type claims and rederive the closed-form expression for the distribution of the severity of ruin, obtained by Drekic et al. (2003, 2004). Finally, we present some numerical results to illustrate the tightness of the bounds obtained in this paper.
