Treasury Bond risk and return, the implications for the hedging of consumption and lessons for asset pricing

All consumption-based models of asset pricing imply that the relation between the conditional mean and conditional volatility of any asset reflects the effectiveness of holding that asset as a hedge against intertemporal variation in the marginal utility of consumption. For Treasury Bonds of various maturities, we find significant positive relations. Our empirical findings support the conclusion that investors must sell bonds short to hedge shocks to marginal utility, because realized bond returns tend to be high (low) when investors least (most) desire an additional dollar of consumption. Implications for special cases of the general consumption-based model are also discussed.     

Causality tests of the relationship between the twin deficits

We re-examine the causality between the twin deficits by testing for Granger non-causality between BD and CAD based on extended causality tests initially developed by Toda and Yamamoto (1995). Using international data from a sample of twenty developed and developing countries, we find evidence of causality (unidirectional or bi-directional) between the twin deficits for some developing countries. However, the results for developed countries are less persuasive. The empirical findings of this study are robust to alternative and independent causality testing procedures.Final revision received: July 2001/Final version received: March 2002     

Using Bayesian methods in strategy research: an extension of Hansenet al.

Hansen, Perry, and Reese ( 2004 ) recently argued for and demonstrated the utility of Bayesian methods for research associated with the resource‐based view (RBV) of the firm. In this paper, we propose that Bayesian approaches are highly relevant not only for strategy problems based on the RBV, but also to its extensions in the areas of dynamic capabilities and co‐evolution of industries and firms. Further, we argue that Bayesian methods are equally applicable for a wide range of strategy research questions at both the micro‐ and macro‐level. Bayesian techniques are especially useful in addressing specific methodological challenges related to firm‐ and individual‐level effects, firm‐level predictive results, precision with small samples, asymmetric distributions, and the treatment of missing data. Moreover, Bayesian methods readily permit the engineering and updating of more realistic, complex models. We provide a specific illustration of the utility of Bayesian approaches in strategy research on entry order and pioneering advantage to show how they can help to inform research that integrates micro‐ and macro‐phenomena within a dynamic and interactive environment.

Corruption,competition and democracy

This paper presents a model of the interaction between corrupt government officials and industrial firms to show that corruption is antithetical to competition. It is hypothesized that a government agent that controls access to a formal market has a self-interest in demanding a bribe payment that serves to limit the number of firms. This corrupt official will also be subject to a detection technology that is a function of the amount of the bribe payment and the number of firms that pay it. Under quite normal assumptions about the shape of the graph of the detection function, multiple equilibria can arise where one equilibrium is characterized by high corruption and low competition, and another is characterized by low corruption and high competition. Some suggestive empirical evidence is presented that supports the main hypothesis that competition and corruption are negatively related.

Thinking Through Dualisms in Urban Policy Mobilities

The growing use of the notion of ‘policy mobilities’ to conceptualize how policy is made and moved across and among cities and urbanized regions has led to worthwhile insights, but has also encouraged some critiques. Many of these address certain dualisms that seem to undergird the policy mobilities approach. This essay engages with three of these apparent dualisms—success/failure, presence/absence and mobilities/immobilities—and argues that while they must be treated with care, they should not be dismissed or expunged a priori. Rather, we argue that there is utility in conceptualizing urban policy mobilities through relational dyads, rather than oppositional dualisms. If studies of policy mobilities, urban or otherwise, are to maintain their momentum, success, failure, presence, absence, mobilities and immobilities should be understood as being intertwined, mutually constituting and reinforcing elements of policymaking.     

An applied ethical analysis system in business

Much of the discussion on business ethics is philosophical in nature. There is no lack of theories and ideals on moral reasoning. What is missing is translating these moral theories and principles into specific, operational procedures that can indicate a proper course of action. Although most business actions are routine and do not raise serious ethical questions, many people experience difficulty in applying their personal moral principles to specific business decisions in ethically-dilemmatic situations.This study seeks to develop a framework that can be utilized to implement personal moral reasoning based on the teleological theory of Utilitarianism and the deontological theory of Ross's Prima Facie Duties in the business decision-making process. The central feature in the framework is a point-system that quantities the ethical worth of a proposed business action and determines whether the action would be ethically desirable if taken. It provides an objective element in an otherwise qualitative ethical inquiry process. This study also illustrates practical applications of the system by analyzing the ethical implications of a proposed action where foreign bribery is involved.Alan Wong is Assistant Professor of Finance, Indiana University Southeast.
