Do Stock Investors Value Corporate Sustainability? Evidence from an Event Study

This paper analyzes the impacts of index inclusions and exclusions on corporate sustainable firms by studying a sample of US stocks that are added to or deleted from the Dow Jones Sustainability World Index over the period 2002?C2008. The impacts are measured in terms of stock return, risk and liquidity. We cannot find any strong evidence that announcement per se has any significant impact on stock return and risk. However, on the day of change, index inclusion (exclusion) stocks experience a significant but temporary increase (decrease) in stock return. Liquidity deteriorates after the announcement day and bounces back significantly near the day of change. Systematic risk shows little change after announce- ments. But, idiosyncratic risk is higher after announcements. The overall results support Harris and Eitan??s (The Journal of Finance 41(4), 815?C829, 1986) price pressure hypothesis, which posits that event announcement does not carry information and any shift in demand (and hence the corresponding price change and liquidity change) is temporary.     

Does Corporate Governance Predict Future Performance? Evidence from Hong Kong

This study uses time‐series data to examine the relation between changes in the quality of corporate governance practices and subsequent market valuation among large listed companies in Hong Kong. The results indicate that firms that exhibit improvements in the quality of corporate governance display a subsequent increase in market valuation, whereas firms that exhibit deterioration in the quality of corporate governance practices tend to encounter a decline in market valuation. Additionally, the impact is greater for firms that are included in the MSCI index or with a China affiliation. The results provide evidence in support of the notion that good corporate governance can predict future market valuation.     

Exchange rate dynamics under alternative optimal interest rate rules

We explore the role of interest rate policy in the exchange rate determination process. Specifically, we derive exchange rate equations from interest rate rules that are theoretically optimal under a few alternative settings. The exchange rate equation depends on its underlying interest rule and its performance could vary across evaluation criteria and sample periods. The exchange rate equation implied by the interest rate rule that allows for interest rate and inflation inertia under commitment offers some encouraging results — exchange rate changes “calibrated” from the equation have a positive and significant correlation with actual data, and offer good direction of change prediction. Our exercise also demonstrates the role of the foreign exchange risk premium in determining exchange rates and the difficulty of explaining exchange rate variability using only policy based fundamentals.     

Modernizing Public Healthcare Governance in Hong Kong: A Case Study of Professional Power in the New Public Management

This article examines Hong Kong's experience in modernizing and corporatizing public healthcare governance in order to enhance management autonomy and service efficiency, against the background of a previous regime of centralized departmental control and amid the worldwide trend of new public management. The reform, culminating in the establishment of a hospital authority, is found to be wrought with intense intra-bureaucratic conflict, as well as rivalries between professional and administrative bureaucrats, between professionals of different sectors, and between medical and para-medical providers. Instead of breaking up traditional professional monopoly and opening up the system to non-medical general management, corporatization has resulted in an unplanned entrenchment and re-empowerment of medical professional power.     

The interest-rate management and sterilization hypotheses for the UK: under fixed exchange rates

This study uses the vector autoregressive (VAR) technique and Granger's definition of causality to examine the interest rate management and sterilization hypotheses of UK for the period 1955.I to 1974.IV. Our findings show that neither the long-term government bond yield nor long-term treasury bill rate of UK can be considered as a policy-determined variable, since each is subject to feedback from UK and US monetary and income variables. In regard to the sterilization hypothesis, our results indicate that the UK domestic credit is an exogenous variable with respect to UK foreign reserves and interest rates. This result supports the implication of the monetary approach to the balance of payments that there was no sterilization in the UK during the fixed exchange rate period.     

Pacific Rim Stock Market Integration Under Different Federal Funds Rate Regimes

This study uses Sims-type vector autoregression technique to examine the stock markets integration among the US and four major Asian-Pacific stock exchanges during 1993 and 1994. The two different sample periods capture the change in US monetary policy in 1994. Empirical results show that when the US was targeting the federal funds rate in 1994, the variations in US stock returns much better explain the variations of stock returns in Hong Kong, Singapore and Australia.     

Dissecting the PPP puzzle: the unconventional roles of nominal exchange rate and price adjustments

The conventional view, as expounded by sticky-price models, is that price adjustment determines the PPP reversion rate. This study examines the mechanism by which PPP deviations are corrected. Nominal exchange rate adjustment, not price adjustment, is shown to be the key engine governing the speed of PPP convergence. Moreover, nominal exchange rates are found to converge much more slowly than prices. With the reversion being driven primarily by nominal exchange rates, real exchange rates also revert at a slower rate than prices, as identified by the PPP puzzle [J. Econ. Lit. 34 (1996) 647].     

Righteousness and Profitableness: The Moral Choices of Contemporary Confucian Entrepreneurs

The present study takes Confucian entrepreneurs as an entry point to portray the dynamics and problems involved in the process of putting moral precepts into practice, a central issue in business ethics. Confucian entrepreneurs are defined as the owners of manufacturing or business firms who harbor the moral values of Confucianism. Other than a brief account of their historical background, 41 subjects from various parts of Mainland China, Taiwan, Hong Kong, Singapore and Kuala Lumpur were selected for in-depth interviews. By studying the moral choices they made in the market, it was discovered that, contrary to the prevalent mode of inquiry in economics either to reduce all social phenomena to rational calculations or to consider moral actions in terms of utilitarian values, their economic action cannot be accounted for by the postulate of utility maximization, and that the efforts to do business according to their moral principles can be very costly. The study also attempts to document how these Confucian entrepreneurs reconciled the conflict between the moral values they cherished and the instrumental goals they pursued, and will seek to uncover how they responded when faced with this dilemma.     

Analysis of a Generalized Penalty Function in a Semi-Markovian Risk Model

Abstract

In this paper an extension of the semi-Markovian risk model studied by Albrecher and Boxma (2005) is considered by allowing for general interclaim times. In such a model, we follow the ideas of Cheung et al. (2010b) and consider a generalization of the Gerber-Shiu function by incorporating two more random variables in the traditional penalty function, namely, the minimum surplus level before ruin and the surplus level immediately after the second last claim prior to ruin. It is shown that the generalized Gerber-Shiu function satisfies a matrix defective renewal equation. Detailed examples are also considered when either the interclaim times or the claim sizes are exponentially distributed. Finally, we also consider the case where the claim arrival process follows a Markovian arrival process. Probabilistic arguments are used to derive the discounted joint distribution of four random variables of interest in this risk model by capitalizing on an existing connection with a particular fluid flow process.
