Dealing with consumer default: Bankruptcy vs garnishment

What are the positive and normative implications of eliminating bankruptcy protection for indebted individuals? Without bankruptcy protection, creditors can collect on defaulted debt to the extent permitted by wage garnishment laws. The elimination lowers the default premium on unsecured debt and permits low-net-worth individuals suffering bad earnings shocks to smooth consumption by borrowing. There is a large increase in consumer debt financed essentially by super-wealthy individuals, a modest drop in capital per worker, and a higher frequency of consumer default. Average welfare rises by 1% of consumption in perpetuity, with about 90% of households favoring the change.     

Target volatility option pricing in the lognormal fractional SABR model

We examine in this article the pricing of target volatility options in the lognormal fractional SABR model. A decomposition formula of Itô's calculus yields an approximation formula for the price of a target volatility option in small time by the technique of freezing the coefficient. A decomposition formula in terms of Malliavin derivatives is also provided. Alternatively, we also derive closed form expressions for a small volatility of volatility expansion of the price of a target volatility option. Numerical experiments show the accuracy of the approximations over a reasonably wide range of parameters.     

Telematics: Decision Time for Detroit

With implications for navigation, safety, entertainment and vehicle maintenance as well as regulation and infrastructure investment in roads, telematics has the potential to transform driving more than any other innovation for decades. In the already well-established Asian telematics industry, revenue tends to come from extra charges at the time of vehicle-sale, with most subsequent services provided free. The US model has evolved differently, with much of the cost of telematics hardware and software subsidized in the initial vehicle sale price and revenue coming from services used. The decision to invest in telematics is therefore riskier in the US. This article first briefly summarizes the potential of telematics. It then analyzes the investment risks, particularly for automakers. It concludes with recommendations on how the US auto industry can minimize risk and make the most of the opportunities.     

BOOTSTRAPPING THE NUMBER OF FACTORS IN THE ARBITRAGE PRICING THEORY

The number of factors in the APT are re-examined through a new methodology called the bootstrap, which provides a nonparametric alternative to the chi-square test used in prior research. Results suggest that the number of statistically significant factors does not increase when the number of firms increases. Moreover, only the first factor is consistently significant across sample sizes of thirty, sixty, and ninety firms.     

Ethical perceptions of Asian managers: evidence of trends in six divergent national contexts

Global link building is having a substantial impact in every sphere of Asian managerial activity. The economic upheavals of the Asian ?nancial crisis have cast a long shadow, and ethical clarity has become a social issue. For instance, corporate performance in terms of long-term survival, growth and global competency is seen to depend to a considerable extent upon the ethical infrastructur of managers and emerging managerial culture in Asia. One ?eld in which Asian managers and their managerial practices are often considered weak is the area of ethical clarity. Corporate managerial leaders in Asia need to develop new responses to the ethical complexities arising out of the increasing global interfaces. In spite of a growing awareness of the importance of ethical centrality in an intensely competitive international business arena, very little empirical work has been conducted to strengthen the relevant management literatures. The purpose of the research reported in this paper was to examine the perceptions of ethical probity among managers in six Asian countries. The results of the study indicate interesting convergences and divergences across countries and organisational demographies. The ?ndings lead to observations of the apparent similarities of ethical conceptualisation in global, societal and often in the organisational arena while revealing noticeable divergences in the domain of individual ethical perceptions.     

Types of synergy and economic value: The impact of acquisitions on merging and rival firms

Acquisitions, in general, have been demonstrated to create economic value. The intuitive reason underlying this value creation stems either from an ability to reduce costs of the combined entity, an ability to charge higher prices, or both. Current research in the area attributes these abilities to an opportunity to utilize a specialized resource. Our focus in this study is to compare three broad classes of resources that contribute to the creation of value. Following the conventional wisdom, these resources are classified as cost of capital related (resulting in financial synergy), cost of production related (resulting in operational synergy), and price related (resulting in collusive synergy). Given the limitations of our sample and research design, we find that collusive synergy is, on average, associated with the highest value. Further, the resources behind financial synergy tend to create more value than the resources behind operational synergy.     

ESTIMATING THE MARKET MODEL ROBUSTLY

There is now considerable evidence in the literature that the ordinary least squares assumptions fail to hold when estimating the market model parameters. This paper describes a robust estimation procedure which provides automatic protection against departures from normality. The market model parameters are then estimated for a sample of securities using both the least squares method and the robust procedure. Analysis shows that the results under the two procedures may differ considerably.     

Growth and inequality: Dependence on the time path of productivity increases (and other structural changes)

This paper examines the significance of the time path of a given productivity increase on growth and inequality. Whereas the time path impacts only the transitional paths of aggregate quantities, it has both transitional and permanent consequences for wealth and income distribution. Hence, the growth-inequality tradeoff generated by a given discrete increase in productivity contrasts sharply with that obtained when the same productivity increase occurs gradually. The latter can generate a Kuznets-type relationship between inequality and per-capita income. Our results suggest that economies with similar aggregate structural characteristics may have different outcomes for income and wealth inequality, depending on the nature of the productivity growth path.
