Mainstreaming Sustainable Development-A Case Study: Ashton Hayes is going Carbon Neutral

The Parish Council of Ashton Hayes in Cheshire voted in November 2005 to try to become England's first carbon neutral village. This grass roots project has grown rapidly in its first year and has engaged a large proportion of village residents. The project has produced a number of impacts on the community and the wider region and these are being evaluated in terms of their environmental, economic and social dimensions. This paper describes the process of project development and implementation and draws some general conclusions from this experience before going on to consider some of the findings of the initial evaluation of the project. We conclude by suggesting that Ashton Hayes provides an interesting case study of a community-led attempt to bring sustainable development into the mainstream and that the challenge remains, as with many community-led initiatives, of how to translate the considerable early momentum of the project into sustainable forms of participation and behaviour.     

Quasi Score is more Efficient than Corrected Score in a Polynomial Measurement Error Model

We consider a polynomial regression model, where the covariate is measured with Gaussian errors. The measurement error variance is supposed to be known. The covariate is normally distributed with known mean and variance. Quasi score (QS) and corrected score (CS) are two consistent estimation methods, where the first makes use of the distribution of the covariate (structural method), while the latter does not (functional method). It may therefore be surmised that the former method is (asymptotically) more efficient than the latter one. This can, indeed, be proved for the regression parameters. We do this by introducing a third, so-called simple score (SS), estimator, the efficiency of which turns out to be intermediate between QS and CS. When one includes structural and functional estimators for the variance of the error in the equation, SS is still more efficient than CS. When the mean and variance of the covariate are not known and have to be estimated as well, one can still maintain that QS is more efficient than SS for the regression parameters.     

On option pricing in binomial market with transaction costs

Option replication is studied in a discrete-time framework with proportional transaction costs. The model represents an extension of the Cox-Ross-Rubinstein binomial option-pricing model to cover the case of proportional transaction costs for one risky asset with different interest rates on bank credit and deposit. Contingent claims are supposed to be 2-dimensional random variables. Explicit formulas for self-financing strategies are obtained for this case.Received: March 2004, Mathematics Subject Classification (2000): 62P05JEL Classification: G11, G13The authors are grateful to an anonymous referee for numerous helpful comments and to Yulia Romaniuk for final corrections.

REAL OPTIONS AND CORPORATE RISK MANAGEMENT

By formulating an integrated strategy that combines the creation and exercise of real options together with other risk management techniques, management can reduce risk and thereby increase firm value. For example, a company that is in a position to delay investing without losing its competitive edge, to abandon a project that becomes unprofitable, or to adjust its operating strategy at low cost can avoid risks and exploit profitable opportunities. But, even when real options are used in this way to limit the risk profile of the firm, financial derivatives can help to hedge any residual risk that would otherwise affect the value of the real options and the overall firm.
An integrated risk management approach requires a careful process of diagnosing a company's risk exposure. First, management must decompose the company's risk exposure to understand the fundamental sources of risk. Second, the company's capacity to bear risk must be determined, which requires an understanding of why individual risks (if left unmanaged) would reduce the value of the firm. Third, different approaches for addressing risk should be explored, ranging from diversification to use of financial derivatives and other contracts to investing in (or exercising) a wide array of real options. Fourth, the firm must properly integrate the different risk management solutions to optimize its strategy.     

Banks and securities markets: Corporate financing in Germany and the United Kingdom

This paper compares corporate financing in the German bank-based and UK market-based systems. Large German firms pay out a lower proportion of their profits as dividends and finance a larger proportion of their investments from retentions. German banks extend more long-term finance to medium-sized firms but UK firms raise more new equity. The paper tests alternative theories of corporate finance. It finds no relation between finance and taxation, and information theories only receive limited support. Instead, it concludes that control models of corporate finance are consistent with observed patterns of finance.     

The effect of the introduction of Cubes on the Nasdaq‐100 index spot‐futures pricing relationship

This paper examines the impact of the introduction of the Nasdaq‐100 Index Tracking Stock (referred to as Cubes) on the pricing relationship between Nasdaq‐100 futures and the underlying index. Observations obtained from tick‐by‐tick Nasdaq‐100 futures transactions and index value data support the hypothesis that the introduction of Cubes in March 1999 has led to improvements in the Nasdaq‐100 index futures pricing efficiency. Both the size and frequency of violations in futures price boundaries appear to be reduced. Furthermore, there appears to be an increase in the speed of the market response to observed violations. These results are attributed to the increased ease in establishing a spot Nasdaq‐100 index position after the introduction of the tracking stock. © 2002 John Wiley & Sons, Inc.
