The impact of a gasoline crisis on retail sales

The gasoline crises of the 1970s demonstrated the need for including gasoline prices and gasoline shortages in models explaining retail sales. In this article, a model is constructed that incorporates the aforementioned variables, other variables, and a lagged sales figure as independent variable. The results indicate a high degree of explanatory power in predicting retail sales for a specialty store chain with a preponderance of their stores in large regional malls that sell a product which lends itself to unplanned purchase behaviour.     

Reducing the ecological footprint of urban cars

This study develops the policy-making capabilities of the Ecological Footprint. The new capabilities we introduce in our Ecological Footprint model allow us to clarify policy options in the face of the increasing management complexity due to a more interconnected and uncertain world. We investigate the effectiveness of three illustrative policy options for reducing the Ecological Footprint of urban car transport: (1) improvements in efficiency/technology, (2) substitution with alternate fuel mixes, and (3) the reduction in demand by altering urban form. We investigate the success of policy options for a subnational case study jurisdiction in Australia, but in the uncertain global context. We use a resilience framework that considers critical social, economic, and environmental variables, multiple scales, and multiple possible futures. We find that delaying policy options to mitigate CO₂ emissions from the transport sector will increase the risks borne by society as a result of future global uncertainty, the uncertain timing of globally coordinated action on climate change and the timing of peak oil. We also find that the success of local policy is affected by the global future which prevails. The use of the Ecological Footprint allows policy to be informed by the consequences of both CO₂ emissions and increasing demand for land. The study provides a decision-making framework that allows local decision makers to make robust policy despite global uncertainty. This framework has wider applicability to other nations and/or subnational jurisdictions worldwide.     

A research agenda for improving national Ecological Footprint accounts

Nation-level Ecological Footprint accounts are currently produced for more than 150 nations, with multiple calculations available for some nations. The data sets that result from these national assessments typically serve as the basis for Footprint calculations at smaller scales, including those for regions, cities, businesses, and individuals. Global Footprint Network's National Footprint Accounts, supported and used by more than 70 major organizations worldwide, contain the most widely used national accounting methodology today. The National Footprint Accounts calculations are undergoing continuous improvement as better data becomes available and new methodologies are developed. In this paper, a community of active Ecological Footprint practitioners and users propose key research priorities for improving national Ecological Footprint accounting. For each of the proposed improvements, we briefly review relevant literature, summarize the current state of debate, and suggest approaches for further development. The research agenda will serve as a reference for a large scale, international research program devoted to furthering the development of national Ecological Footprint accounting methodology.     

Trading spaces: Calculating embodied Ecological Footprints in international trade using a Product Land Use Matrix (PLUM)

Nations import and export biophysical resources. With many ecosystems worldwide under mounting stress, countries may be increasingly interested in knowing the extent and origin of their ecological imports and dependencies. In this paper the Ecological Footprint is used as a tool to measure the biophysical (as opposed to financial) value of international trade flows. This paper attempts to answer the following question: How large of an Ecological Footprint does a given country exert inside the borders of each of its trading partners? Records in the UN COMTRADE bilateral trade database are multiplied by a matrix of per-product Footprint yield coefficients to translate from values in dollars and tonnes to units of hectares. The results show that the largest interregional flows are from Latin to North America, and from North America to Asia-Pacific. Grouping countries by GDP, high and middle income countries appear in Footprint terms to trade predominantly with other high and middle income countries and much less with low income countries.     

Financing the global supply chain: Growing need for management action

This article investigates a growing desire by companies to better manage the financing of the global Management Action supply chain and explores best practices. Supply‐chain managers and finance or treasury managers, however, live in different worlds, and integration does not come easily. The article argues that decentralized finance functions lead to financial inefficiencies. The authors identify five subarchitectures to competitive supply chains and argue that visualizing the supply chain financially is the first step to controlling and improving it. Finance is embedded in every step of the supply chain — and business model. Management guidelines of what to change, what to eliminate, and what to adapt are presented along with the new starting points of strategy and customers' ever‐changing needs. Consequently, the end game is profit maximization rather than only cost minimization, and both within acceptable risk parameters. © 2010 Wiley Periodicals, Inc.     

An Examination into the Relevance of the Median Voter Model: Empirical Evidence Offers Support for the Model and Certain Uses

Abstract . This study analyzes some criticisms of the empirical use of the median voter model. In an attempt to evaluate these criticisms, a local school expenditure model is constructed which incorporates various income measures and various measures of tax price. Results indicate that median income outperforms other income measures. This empirical evidence offers support for the median voter model and its use in empirical work. The median tax price measure proved not to be of statistical significance. It should not be used without independent validation. Moreover, it does not outperform other tax price measures, in this test, at least. Further research is needed to explain this seeming anomaly.     

Pricing Eurodollar futures options with the Ho and Lee and Black,Derman, and Toy models: An empirical comparison

This article compares empirically the Ho and Lee (1986) and Black, Derman, and Toy (1990) discrete-time debt option pricing models in the pricing of Eurodollar futures options over the period from March 1997 through February 1998 using daily data. The results indicate that both models performed well. The average absolute pricing errors over the sample period were less than one tick (0.01) in every case. The Black, Derman, and Toy model slightly outperformed the Ho and Lee model in the pricing of in-the-money call options and out-of-the-money put options over the period studied. © 1999 John Wiley & Sons, Inc.

THE IMPACT OF DROUGHT ON THE NATIONAL ACCOUNTS FOR LIVESTOCK IN SAHELIAN COUNTRIES

The evaluation of livestock production in the United Nations System of National Accounts implies a measure which is inconsistent with the general principle evaluation of production in this system.
This paper deals with a critical appraisal of the methods used by the SNA and two sahelian countries in livestock accounting.
Finally, estimations of NIGER'S GDP over the period 1983 to 1985 are carried out, using the four livestock production assessments presented. Differences in GDP's evaluations are large, reaching 17 percent in 1984 and 7 percent in 1985 in terms of rate of growth.     

The etiology of liquidity crises and how managers can be better prepared

Financial shocks have become an increasingly pervasive feature of the global economic landscape. Among the two most prominent that have faced corporate managers during the past decade are the bursting of the technology bubble in 2000 and the ongoing global financial and economic crisis. These not only have had a chilling impact on the industries most directly involved, but they also occasioned a massive spillover into other industrial sectors, and in financial markets in general. “Contagion” is perhaps the most devastating aspect of such crises. © 2009 Wiley Periodicals, Inc.
