The generalized bin packing problem

In the Generalized Bin Packing Problem (GBPP), given two sets of compulsory and non-compulsory items characterized by volume and profit and a set of bins with given volume and cost, we want to select the subset of profitable non-compulsory items to be loaded together with the compulsory ones into the appropriate bins in order to minimize the total net cost. Lower and upper bounds to the GBPP are given. The results of extensive computational experiments show that the proposed procedures are efficient and the bounds are tight.     

Corporate response to an ethical incident: the case of an energy company in New Zealand

The ethical behaviour and social responsibility of private companies, and in particular large corporations, is an important area of enquiry in contemporary social, economic and political thinking. In the past, a company's behaviour would be considered responsible as long as it stayed within the law of the society in which it operated or existed. Although this may be necessary, it is no longer sufficient. In this paper, we examine an energy company's response to an ethical incident in New Zealand which prompted different responses across the country about the role of business in society. Thus, we argue that when a corporation is accused of unethical behaviour, executives of the company are usually compelled to offer responses to defend their actions and corporate image. Further, we use communicative response model, social issue life cycle theory, and organisational learning, to analyse the incident and how the company responded. Using social issues life cycle theory and organisational learning theory, we demonstrate that sustained pressure can potentially trigger a change of strategy that may serve to improve the ethical posture of a corporation and thereby improve the corporate image long term. We conclude that, although corporations may understand the significance of social issues to the performance and success of their business, this same understanding does not always translate into meaningful social action.     

Modelling the Extensive Margin of World Trade: New Evidence on GATT and WTO Membership

Recent literature has argued that, contrary to the results of a seminal paper by Rose (2004), General Agreement on Tariffs and Trade (GATT)/World Trade Organization (WTO) membership does promote bilateral trade, at least for developed economies and if membership includes non‐formal compliance. We review the literature to identify open issues. We then develop a simple extension of the gravity model that gives rise to an extensive country margin of trade separating positive trade from zero trade country pairs. The model is used to identify WTO membership effects at both the intensive and the extensive margins. Empirical estimation of this model, based on Poisson pseudo‐maximum likelihood methods with exporter and importer fixed effects, allows us to readdress the empirical issue of whether GATT/WTO membership does or does not promote trade. We find that GATT membership was successful on the extensive margin of world trade but not on the intensive margin. For the recent WTO episode (1995–2008), we find consistent and robust evidence for a substantial trade‐creating role of membership which is driven primarily by the intensive margin. WTO membership results in higher bilateral trade of about 40 per cent.     

WAS THE GOLD STANDARD REALLY DESTABILIZING?

This paper investigates the extent to which the high macroeconomic volatility experienced in the classical Gold Standard era of US history can be attributed to the monetary policy regime per se as distinct from other shocks. For this purpose, we estimate a small dynamic stochastic general equilibrium model for the classical Gold Standard era. We use this model to conduct a counterfactual experiment to assess whether a monetary policy conducted on the basis of a Taylor rule characterizing the Great Moderation data would have led to different outcomes for macroeconomic volatility and welfare in the Gold Standard era. The counterfactual Taylor rule significantly reduces inflation volatility, but at the cost of higher real‐money and interest‐rate volatility. Output volatility is very similar. The end result is no welfare improvement. Copyright © 2012 John Wiley & Sons, Ltd.     

A useful tool for forecasting the Euro-area business cycle phases

Based on a novel extension of existing multivariate Markov-switching models, we provide the reader with a useful tool for analyzing current business conditions and making predictions about the future state of the Euro-area economy in real time. Apart from the Industrial Production Index, we find that the European Commission Industrial Confidence Indicator, which is issued with no delay, is very useful for constructing the real-time predictions.     

Redistribution and growth: Pareto improvements

This paper analyzes the relationship between income distribution and economic growth. It introduces heterogeneous households who have preferences for leisure into Grossman and Helpman's model of endogenous growth (in which income distribution has no effect on economic growth). Wealth distribution affects the endogenous rate of growth as the labor supply of each individual responds inversely to his permanent income. When the labor Engel curve is concave (convex), unequal wealth distribution decreases (increases) the rate of growth. Pareto-improving-growth-enhancing wealth redistributions are characterized.     

Missionaries,Mercenaries Or Car Salesmen? MBA Teaching In Malaysia*

Increasing academic attention is being given to the role of management gurus, consultants, managers and academic researchers in the international diffusion of Western management ideas. This is part of wider debates on knowledge, power and globalization. Relatively little attention has been paid to the mechanisms through which diffusion takes place and, in particular, the role of academics as lecturers and business schools as disseminators of management knowledge at home and abroad. This paper draws on the authors' personal experiences and perceptions of teaching on an Executive MBA programme in Malaysia and those of their students.
Management education is growing rapidly in many regions of the world and has become highly commodified and commercialized, with Western universities competing in emerging markets for potentially lucrative local opportunities and foreign students or 'consumers'. Accordingly, the process of diffusion of Western management ideas is examined through a consumption perspective which treats the foreign MBA as a standardized commodity (much like the foreign car) with particular use, symbolic and exchange values. However, the limits of the consumption perspective in terms of both consumer sovereignty and subordination are also established in revealing deeper and more dynamic relations of power. Moreover, it is argued that while there are parallels with domestic consumption of MBAs, the teaching of MBAs in Malaysia generates added ambivalence among learners founded on global–local and development–imperialism dynamics and tensions.     

THE NONPROFIT SECTOR OF THE U.S. ECONOMY: A METHODOLOGICAL STATEMENT

United States input-output accounts identify and measure the interrelationships between the various industries in the United States economy. However, these accounts do not identify nonprofit activities from their for-profit counterparts in the service-producing sector. This paper, prepared by Gabriel Rudney and Paula Young, presents the methodology and summary data produced by disaggregating the service-producing industries to identify separately nonprofit activities.
The input-output accounts for 1977 produced in this study include 107 industries, but in this paper the results are summarized into 14 industries showing only nonprofit and for-profit components. The GNP and total outputs in this study are consistent with the revised input-output accounts for 1977 prepared by the U.S. Department of Commerce, Bureau of Economic Analysis.
