Pasinetti's ‘Structural Change and Economic Growth’: A Conceptual Excursus

A clear and organic exposition of Pasinetti's theoretical framework of Structural Change and Economic Growth has been prevented by misunderstandings and ambiguities concerning basic categories and terminology. The pre-institutional character of the approach, the nature of its equilibrium paths and the significance—and normative character—of the ‘natural’ economic system are some of the most controversial issues. The aim of this article is to present a conceptual excursus of the model to establish a solid foundation for fruitful discussions to be held with other Classical approaches.

Forecasting crude oil spot price using OECD petroleum inventory levels

This paper presents a short-term monthly forecasting model of West Texas Intermediate crude oil spot price using OECD petroleum inventory levels. Theoretically, petroleum inventory levels are a measure of the balance, or imbalance, between petroleum production and demand, and thus provide a good market barometer of crude oil price change. Based on an understanding of petroleum market fundamentals and observed market behavior during the post-Gulf War period, the model was developed with the objectives of being both simple and practical, with required data readily available. As a result, the model is useful to industry and government decision-makers in forecasting price and investigating the impacts of changes on price, should inventories, production, imports, or demand change. This work is partially sponsored by the Office of Strategic Petroleum Reserve, Department of Energy, USA, and was presented at the International Atlantic Economic Conference, Athens, Greece, March 2001.     

The Willingness to Accept Value of Statistical Life Relative to the Willingness to Pay Value: Evidence and Policy Implications

Large disparities between willingness to accept (WTA) and willingness to pay (WTP) based values of statistical life are commonly encountered in empirical studies. Standard economic theory suggests that if a public good is easily substitutable there should be no marked disparity between WTA and WTP values for the good, though the disparity increases with reduced substitutability. However, psychologists have shown that people often treat gains and losses asymmetrically and tend to require a substantially larger increase in wealth to compensate for a loss than the amount they would be willing to pay for an equivalent gain. Although most transport projects may aim to improve safety, situations arise when a relaxation of an existing regulation saves resources but increases the risk of death and injuries. A survey was recently carried out in New Zealand to determine people’s willingness to pay to reduce road risks and their willingness to accept compensation for an increase in risk. This paper reports the disparity observed between the two measures and considers some of the problems posed for policymakers.
