EFFECTS OF SECTOR AGGREGATION ON CO2 MULTIPLIERS IN MULTIREGIONAL INPUT–OUTPUT ANALYSES

The past few years have seen the emergence of several global multiregional input–output (MRIO) databases. Due to the cost and complexity of developing such extensive tables, industry sectors are generally represented at a rather aggregate level. Currently, one of the most important applications of input–output analysis is environmental assessments, for which highly aggregate sectors may not be sufficient to yield accurate results. We experiment with four of the most important global MRIO systems available, analyzing the sensitivity of a set of aggregate CO₂ multipliers to aggregations in the MRIO tables used to calculate them. Across databases, we find (a) significant sensitivity to background system detail and (b) that sub-sectors contained within the same aggregate MRIO sector may exhibit highly different carbon multipliers. We conclude that the additional information provided by the extra sector detail may warrant the additional costs of compilation, due to the heterogeneous nature of economic sectors in terms of their environmental characteristics.     

Research or practice: the debate goes on

Summary If research is superior to practice the difference does not appear to be in the process that is used. Inquiry and problem-solving are, in fact, based on the same process, decision-making. Both involved the use of an analysis-synthesis-evaluation sequence, both may involve deduction, but they also have the same inductive flaws, and both produce results that are of great benefit to mankind. Thus, if there is a difference, it must have something to do with the skills the individual brings to the process.Competent decision makers analyze and define the situation that exists, distinguish problems from symptoms and identify the problems that should be considered. They think creatively as they generate options using brainstorming, synectics, and lateral thinking. They use logic to test the ideas involved in each step of the process, make assumptions, test inferences, interpret statements, and evaluate arguments. They demand evidence for claims that are made and think critically as they weigh, reconcile, and assess arguments using dialogue, discussion, and debate. And they apply appropriate values and ethics before they make decisions. These are the skills that should be taught in schools for if there is any superiority, it is not intrinsic to the process, it is within the decision maker.This paper was first presented at a conference of the American Society of Mechanical Engineers     

UK food shopping in the 1950s: the social context of customer loyalty

Food shopping – although often dismissed as dreary necessity – has always served a range of latent functions. In the 1950s, food storage limitations and tight budgets gave rise to weekly – often daily – shopping patterns that also allowed shoppers to meet certain social needs. Going to food shops, and the way that customer service was organized, produced significant interactional opportunities which were valued by participants. Exchanging news with other customers may have reinforced shopping patterns but shopkeepers, and knowledgeable assistants, were also useful intermediaries for product and usage information. Functional specialization in food commodities bestowed the aura of expertise, and direct accountability for the quality of what was sold provided a more personal style of retailing than is currently typical. Much depended on the perception of relationships. The 1950s were an important transitional period in the UK. Rationing gave way to wider choice and availability, while the market position of corner shops was increasingly eclipsed by town centre supermarkets. This article explores the social context of food shopping, and its relationship to the specific issue of customer loyalty.     

Is It Who You Know? Entrepreneurs and Bankers in Sao Paulo, Brazil, at the Turn of the Twentieth Century

This article examines the trust-producing mechanisms investorsand financiers used in São Paulo, Brazil, to determinewhere to invest their money in the late nineteenth and earlytwentieth centuries. The coffee boom that began in the 1880sspurred bursts of new domestic business development that transformedSão Paulo into Brazil's industrial leader. Using shareholderand director data from an array of business sectors, this articledemonstrates that early development (1856–1905) of theinstitutions that provided business finance was accompaniedby highly personal relationships between financier and entrepreneur.By the early twentieth century (1906–1920), rapid economicgrowth and business diversification rendered these personalconnections inadequate and hence less important to businessfinance. Investors and directors concentrated their energiesand their money, abandoning the practice of forming broad connectionsin general—and connections to a bank in particular—andturned to the stock market instead. By providing an alternativeto personal forms of trust production, the rise of impersonalintermediation promoted the significantly broadened market forcorporate business formation that underwrote São Paulo'seconomic transformation.     

Anti-Poverty Programs in Indonesia

Between 1994/95 and 1997/98, Indonesia's spending on anti-poverty programs grew from 0.1% to 0.3% of GDP. The introduction of the 'social safety net' raised anti-poverty spending to 1.4% of GDP in 1998/99 and changed its main focus from job creation schemes, financed mainly by loans and grants to small firms and community groups, to in-kind subsidies for rice, public health care, scholarships for children in poor families and grants to schools in poorareas. The most accurately targeted program was health care, which covered twice as many people in the two poorest deciles as in the remaining eight. For most other programs, this targeting ratio was only about 1.5. We argue that the education and health care programs were the most successful, and doubt that the rice subsidy, job creation and loans schemes were worthwhile.     

THE CHANGING ROLE OF NON-FARM ACTIVITIES IN AGRICULTURAL HOUSEHOLDS IN INDONESIA: SOME INSIGHTS FROM THE AGRICULTURAL CENSUSES

The literature on off-farm sources of income in rural areas of developing countries continues to grow. This paper uses data from the household income surveys carried out as part of the 1983 and 1993 agricultural censuses to explore aspects of the changing role of off-farm income sources for agricultural households in different parts of Indonesia. The paper examines variations in the ratio of off-farm to total agricultural household income by holding size, by total household income class and by province. It also examines the linkages between on-farm and off-farm income growth. Comparisons are made with findings from other parts of Asia and elsewhere in the developing world.     

MARKET STRUCTURE AND TRADING VOLUME

Historically, trading volume reported for NASDAQ stocks has been overstated vis‐à‐vis New York Stock Exchange (NYSE) stocks, both because of the dealer's participation in trades as a market maker and because of interdealer trading. Beginning in 1997, the Securities and Exchange Commission changed order‐handling rules and trade‐reporting rules, which may have reduced or eliminated the overstatement of NASDAQ trading. We examine trading volumes of firms changing from NASDAQ to the NYSE since 1997 and document that reported trading volume for NASDAQ stocks continues to be overstated. Moreover, the degree of overstatement is much larger for firms with high trading volume.
