Examining the global environmental impact of regional consumption activities — Part 1: A technical note on combining input-output and ecological footprint analysis

In recent years there have been a number of attempts to develop a more comprehensive approach to the issue of measuring resource use and/or pollution generation embodied in trade flows, including contributions that combine input-output techniques and Ecological Footprint analysis. In this two-part paper we describe how to enumerate the resource and/or pollution content of inter-regional and inter-national trade flows (Part 1) and we present a literature review of recent methodological and empirical developments (Part 2). It is straightforward in principle to extend the basic input-output approach to capture international trade flows. However, in practice, problems of data availability and compatibility, and of computability of extended input-output matrices, mean that simplifying assumptions are generally applied, but with the implications of these assumptions often not made fully explicit. What appears to be absent from previous applications is an account of the analytical method by which Ecological Footprints should ideally be estimated in an international input-output accounting analysis. This allows an explicit analysis of the problems that prevent the application of the full method and identification of the most appropriate short-cut methods in a transparent way. The objective of this paper is to provide such an account.     

A bed management strategy for overcrowding in the emergency department

In 2006, the Institute of Medicine cited growing visit volumes, hospital closures, financial pressures, and operational inefficiencies as the principal reasons for emergency department (ED) overcrowding and called for regulatory measures to resolve the problem. A Midwest medical center with 59,000 annual ED visits instituted a bed management strategy to decrease the need to board, or hold, admitted hospital patients in the ED awaiting transfer to an inpatient care unit. This strategy was successful in improving the hold time from an average of 216 minutes to 103 minutes, or by 52%. This allowed the staff at the hospital to care for an additional 2,936 patients. During this same time, the overall hospital mortality decreased by 0.07% and patient satisfaction scores improved 1%. The greatest outcome from this intervention was realized in the potential revenue increase of over $2 million.     

Justifying health IT investments: A process model of framing practices and reputational value

Despite important research contributions on the financial and operational dimensions of information technology (IT) value, justifying health IT (HIT) investments remains a difficult and enduring issue for IT managers. Recent work has expanded our understanding of HIT value, by focusing on the initial resource allocation stage, and through conceptualizations of value across multiple dimensions. Building on these developments, we adopt a performative perspective to examine the research question of how practitioners justify early stage HIT investments, with a focus on reputational value. We explored this question through a comparative field study of two hospital organizations in the English National Health Service (NHS). We found that practitioners' temporally orientated framing practices matter in justifying HIT investments, enacting different possibilities for reputational value. We develop a process model to explain these dynamics and highlight the mutability of reputational value, which can lead to different possibilities for restoring, enhancing, or maintaining reputation. We conclude by discussing the implications for justifying HIT investments.     

A new argument using embeddedness and sensemaking to explain small firms' responses to employment regulation

In this essay, we develop a new argument about how the concept of embeddedness and a sensemaking approach can be used to theorise small firms' regulatory responses, especially to employment regulation. We want to move beyond the simplistic and narrow conceptualisations of resistant action in small firms in response to regulation. We contribute to theorising on small firms' regulatory responses by developing an embedded account of social action that takes us beyond the dichotomy of individualised (micro) and institutional accounts (macro) explanations of firm behaviour. Our argument emphasises the situatedness of small firm behaviour shaped by, and in turn shaping, the contexts in which they are embedded. We go beyond stereotypes to give a nuanced account of situated action. In conclusion, we briefly outline how our ideas can be operationalised to explain small firms' diverse responses to regulation.     

Accounting for value added embodied in trade and consumption: an intercomparison of global multiregional input–output databases

Global multiregional input–output (MRIO) tables constitute detailed accounts of the economic activity worldwide. Global trade models based on MRIO tables are being used to calculate important economic and environmental indicators such as value added in trade or the carbon footprint of nations. Such applications are highly relevant in international trade and climate policy negotiations, and consequently MRIO model results are being scrutinized for their accuracy and reproducibility. We investigate the variation in results from three major MRIO databases by comparing underlying economic data and territorial and consumption-based results across databases. Although global value-added accounts were similar across databases, we find some significant differences at the level of individual countries and sectors. Model disagreement was relatively stable from the territorial to the consumption perspective. Pairwise matrix comparison statistics indicated that the Global Trade Analysis Project and World Input-Output Database MRIO tables were overall more similar to each other than either was to the Eora database.     

The Impact of Banality, Risky Shift and Escalating Commitment on Ethical Decision Making

This paper posits that organizational variables are the factors that lead to the moral decline of companies like Enron and Worldcom. The individuals involved created environments within the organizations that precipitated a spiral of unethical decision-making. It is proposed that at the executive level, it is the organizational factors associated with power and decision-making that have the critical influence on moral and ethical behavior. The study has used variables that were deemed to be surrogate measures of the ethical violations (OSHA and EPA violations), the risky shift phenomenon (executive team size), banality of wrong-doing (reputation score for firms) and escalating commitment (tenure with the firm/change in revenue for declining firms). The research found that there were small correlations between ethical violations and the three organizational variables.     

The drift factor in biased futures index pricing models: A new look

The presence of bias in index futures prices has been investigated in various research studies. Redfield ( 11 ) asserted that the U.S. Dollar Index (USDX) futures contract traded on the U.S. Cotton Exchange (now the FINEX division of the New York Board of Trade) could be systematically arbitraged for nontrivial returns because it is expressed in so‐called “European terms” (foreign currency units/U.S. dollar). Eytan, Harpaz, and Krull ( 4 ) (EHK) developed a theoretical factor using Brownian motion to correct for the European terms and the bias due to the USDX index being expressed as a geometric average. Harpaz, Krull, and Yagil ( 5 ) empirically tested the EHK index. They used the historical volatility to proxy the EHK volatility specification. Since 1990, it has become more commonplace to use option‐implied volatility for forecasting future volatility. Therefore, we have substituted option implied volatilities into EHK's correction factor and hypothesized that the correction factor is “better” ex ante and therefore should lead to better futures model pricing. We tested this conjecture using twelve contracts from 1995 through 1997 and found that the use of implied volatility did not improve the bias correction over the use of historical volatility. Furthermore, no matter which volatility specification we used, the model futures price appeared to be mis‐specified. To investigate further, we added a simple naïve δ based on a modification of the adaptive expectations model. Repeating the tests using this naïve “drift” factor, it performed substantially better than the other two specifications. Our conclusion is that there may be a need to take a new look at the drift‐factor specification currently in use. © 2002 Wiley Periodicals, Inc. Jrl Fut Mark 22:579–598, 2002     

A Metropolitan Transaction-Based Commercial Price Index: A Time-Varying Parameter Approach

This study examines the usefulness of time-varying parameter techniques for constructing reliable transaction-based commercial price indices for metropolitan areas. Time-varying parameter techniques allow the implicit prices of differing quality characteristics to vary intertemporally, overcoming the potential bias imposed by holding implicit prices fixed and simply interpreting time dummy variables as in a conventional hedonic approach. This paper empirically investigates three time-varying parameter methods (Chained, Laspeyres, and Paasche) and considers the potential for sample selection bias. Precision measures are constructed to examine the reliability of the respective indices.
