Managing motorization in sustainable transport planning: the Singapore experience

The primary objective of this paper is to make a connection between the Singapore story of land transport policy development and the pathway towards sustainable transport planning. Its innovation is to allow a parallel growth in motorization and public transit. The Singapore experience shows how a range of well-coordinated policies including efforts to control the number of cars in both ownership and usage, and at the same time increase the availability and rider-ship of public transit contribute to a sustainable transport system. The Singapore model provides a valuable reference for not only developing an alternative approach towards sustainable transport in countries where motorization is desired but also for understanding the various parameters important to the formulation of management policies. In particular, the paper contends the Singapore experience provides a model for Asian nations and cities.

The Internationalization of Spanish- and Portuguese-Speaking Banks

This article investigates which variables affect the location choice of banks from Spanish- and Portuguese-speaking countries in their process of internationalization. The article compares the differences in these variables for public and private banks. The sample consists of 141 banks operating in 58 countries. Results show that internationalization is undertaken by the largest banks, which preferably choose countries with similar language, close to the home country, and with the most opportunity for growth. Additionally, the effects of certain explanatory variables on the probability of expanding to a given country are different for public and private banks.

Bundling as a new product introduction strategy: The role of brand image and bundle features

Marketers can bundle an unknown brand with a strong brand as a new product introduction strategy. Drawing upon the categorization theory and the elaboration likelihood model, this study examines how a new brand can benefit from bundling with a strong brand. The results of two studies indicate that consumers’ quality perception of a new brand will be affected by the brand image of a bundle partner, and this effect is moderated by the bundle forms and the complementarity of bundle components. Academic and managerial implications of these findings are presented, along with suggestions for further research.     

The incremental value of a futures hedge using realized volatility

A number of prior studies have developed a variety of multivariate volatility models to describe the joint distribution of spot and futures, and have applied the results to form the optimal futures hedge. In this study, the authors propose a new class of multivariate volatility models encompassing realized volatility (RV) estimates to estimate the risk‐minimizing hedge ratio, and compare the hedging performance of the proposed models with those generated by return‐based models. In an out‐of‐sample context with a daily rebalancing approach, based on an extensive set of statistical and economic performance measures, the empirical results show that improvement can be substantial when switching from daily to intraday. This essentially comes from the advantage that the intraday‐based RV potentially can provide more accurate daily covariance matrix estimates than RV utilizing daily prices. Finally, this study also analyzes the effect of hedge horizon on hedge ratio and hedging effectiveness for both the in‐sample and the out‐of‐sample data. © 2009 Wiley Periodicals, Inc.
