Evaluating environmental and social performance of large Portuguese companies: a balanced scorecard approach

A thematic balanced scorecard format was used to address environmental and social performance evaluation of 13 large companies operating in Portugal. Financial aspects of environmental and social company activities are also included. Companies were categorized as to their actual performance status using a predefined performance framework. Three categories were found: compliance with the law while emphasizing pollution control, pollution prevention and eco‐efficiency. Management tools and procedural matters were found to be most relevant for categorization. Often, reported information did not allow for quantitative evaluation of environmental burden reduction. Use of the thematic balanced scorecard format was useful to better understand the strengths and weaknesses of links between objectives and measurements, initiatives and achievements. Improvement as to environmental performance was found to be paralleled by increased social performance, suggesting that a multi‐level ‘sustainability’ performance categorization of these Portuguese companies is feasible. Driving forces for environmental management initiatives were found to differ by category of performance. Copyright © 2005 John Wiley & Sons, Ltd and ERP Environment.     

STOCK RETURNS AND VOLATILITY ON CHINA'S STOCK MARKETS

We examine time‐series features of stock returns and volatility, as well as the relation between return and volatility in four of China's stock exchanges. Variance ratio tests reject the hypothesis that stock returns follow a random walk. We find evidence of long memory of returns. Application of GARCH and EGARCH models provides strong evidence of time‐varying volatility and shows volatility is highly persistent and predictable. The results of GARCH‐M do not show any relation between expected returns and expected risk. Daily trading volume used as a proxy for information arrival time has no significant explanatory power for the conditional volatility of daily returns. JEL classification: G15     

High‐Performance Work System and Organizational Turnover in East and Southeast Asian Countries1

In this paper, we examine the impact of high‐performance work systems (HPWSs) on both voluntary and involuntary organizational turnover rates. Most research on this topic has been done in the United States. Given the global competitive pressures confronting many of the countries of East and Southeast Asia, companies in this region are seeking to become more flexible and often adapt HPWSs practices. We explore the impact of HPWSs in both locally owned companies and subsidiaries of multinational corporations in Korea, Taiwan, Singapore, and Thailand. These countries have significantly different national cultures from the United States and most other Western countries and HPWSs effects in relation to turnover might vary from the studies based in the United States. Our findings are, however, somewhat consistent with U.S.‐based studies. In fact, HPWSs were found to be more effective in reducing turnover in locally owned companies than in subsidiaries of Western and Japanese multinational companies.     

Implementing a corporate environmental strategy: establishing coordination and control within multinational companies

This article presents the results of an empirical study that investigated coordination and control within multinational companies over six key aspects of their environmental strategy. Specifically, it first examines the level of centralization of these key issues. Second, it investigates whether there is a positive relation between three variables associated with organizational complexity and the level of centralization of the environmental issues. Statistical analyses of the data obtained from a sample of 98 North American multinationals were conducted. The study's results revealed that most companies have adopted a global environmental standard to govern their worldwide business activities that is supported by strong central controls over both environmental performance evaluation of facilities and decisions regarding the development of environmental programs. Results also revealed that there are limited links between organizational complexity and most aspects of the environmental strategy. Copyright © 2006 John Wiley & Sons, Ltd and ERP Environment.     

Identifying technically efficient fishing vessels: a non‐empty,minimal subset approach

Stochastic frontier models are often employed to estimate fishing vessel technical efficiency. Under certain assumptions, these models yield efficiency measures that are means of truncated normal distributions. We argue that these measures are flawed, and use the results of Horrace ( 2005 ) to estimate efficiency for 39 vessels in the Northeast Atlantic herring fleet, based on each vessel's probability of being efficient. We develop a subset selection technique to identify groups of efficient vessels at pre‐specified probability levels. When homogeneous production is assumed, inferential inconsistencies exist between our methods and the methods of ranking the means of the technical inefficiency distributions for each vessel. When production is allowed to be heterogeneous, these inconsistencies are mitigated. Copyright © 2007 John Wiley & Sons, Ltd.     

The quality of consumers' decision‐making in the environment of e‐commerce

It is very important that e‐commerce practitioners leverage the technological power (e.g., information control) of the Internet in order to provide consumers with the information they need to make purchasing decisions. In this study, it is hypothesized that, to improve decision‐making quality, the degree of information control should be matched to the degree of expertise of consumers. The experiment method was used to test the hypothesis, and 120 student subjects voluntarily participated in the experiment. The empirical results of the study show that experts perform better at decision making in high‐information conditions, whereas novices perform better in low‐control conditions. The results of this research strongly support the match hypothesis of information control. © 2006 Wiley Periodicals, Inc.     

Velocity Effects of Increased Variability in Monetary Growth in Egypt: A Test of Friedman's Velocity Hypothesis

Abstract: This paper tests Friedman's hypothesis that increased variability in the growth of money supply causes velocity to decline, using Egyptian data from the period 1960–99. The monetary aggregates M1 and M2 are decomposed into anticipated and unanticipated components and the variability of money growth is computed as the standard deviation of five years of monetary growth rates. Cointegration tests show that there is a statistically significant long‐run relationship between the variability in money growth and velocity, for both M1 and M2. However, while increased variability in the growth of M2 is found to be associated with lower velocity — supporting Friedman's velocity hypothesis — increased variability in the growth of M1 seems to have no influence on velocity, possibly because the definition of M1 has changed over time. The findings also suggest that anticipated movements in M2 volatility are not neutral, in the sense that they do affect velocity. An important implication is that the scope for discretionary monetary policy in Egypt is somewhat circumscribed in the short run. However, if the Central Bank of Egypt were to make its decisions more transparent and pre‐announce its policies, then velocity would be more predictable and monetary policy more potent.     

Industrial Targeting and Non‐shiftable Capital in the Harris–Todaro Model*

This paper shows that, in the 2 × 3 sector‐specific capital Harris–Todaro model, capital growth owing to either domestic or foreign investment always enhances the welfare of the country (i.e. non‐immiserizing), and this result of non‐immiserizing foreign investment holds regardless of initial holdings of foreign capital; the policy of industrial targeting via capital investment is more effective vis‐à‐vis the (neoclassical) 2 × 2 mobile‐capital Harris–Todaro model or the Heckscher–Ohlin model; in contrast to the recent generalization by Marjit and Beladi (2003 ), capital growth cannot be immiserizing in the present model, even if it destroys the “envelope theorem.”     

Creditor Rights, Enforcement, and Bank Loans

We examine whether differences in legal protection affect the size, maturity, and interest rate spread on loans to borrowers in 48 countries. Results show that banks respond to poor enforceability of contracts by reducing loan amounts, shortening loan maturities, and increasing loan spreads. These effects are both statistically significant and economically large. While stronger creditor rights reduce spreads, they do not seem to matter for loan size and maturity. Overall, we show that variation in enforceability of contracts matters a great deal more to how loans are structured and how they are priced.
