This paper evaluates the performance of Poisson and negative binomial (NB) regression models in establishing the relationship between truck accidents and geometric design of road sections. Three types of models are considered. Poisson regression, zero-inflated Poisson (ZIP) regression, and NB...

Market share OPEC lost in defending higher prices from 1979-1985 is being steadily regained and is projected to exceed 50% by 2000. World oil markets are likely to be as vulnerable to monopoly influence as they were 20 years ago, as OPEC regains lost market share. The US economy appears to be as...

The partial monopolization of the world oil market by the OPEC cartel has produced significant economic costs to the economies of the world. This paper reports estimates of the costs of monopolization of oil to the U.S. over the period 1972-1991. Two fundamental assumptions of the analysis are,...

Oil dependence remains a potentially serious economic and strategic problem for the United States. This report updates previous estimates of the costs of oil dependence to the U.S. economy and introduces several methodological enhancements. Estimates of the costs to the U.S. economy of the oil...

Over the past quarter century the United States` dependence on oil has cost its economy on the order of $5 trillion. Oil dependence is defined as economically significant consumption of oil, given price inelastic demand in the short and long run and given the ability of the OPEC cartel to use...

The frequently controversial Federal Automotive Fuel Economy Standards (a.k.a. Corporate Average Fuel Economy (CAFE) standards) have in fact been a notable success. This paper attempts to explain why the CAFE standards have been such a successful energy policy. It begins by demonstrating that...

This report presents a risk analysis of world conventional oil resource production, depletion, expansion, and a possible transition to unconventional oil resources such as oil sands, heavy oil and shale oil over the period 2000 to 2050. Risk analysis uses Monte Carlo simulation methods to...

For thirty years, dependence on oil has been a significant problem for the United States. Oil dependence is not simply a matter of how much oil we import. It is a syndrome, a combination of the vulnerability of the U.S. economy to higher oil prices and oil price shocks and a concentration of...
