The illicit dealing in gemstones (including diamonds) is a fast growing activity in African countries which produce these minerals. Zaire and Angola are two extreme examples, but by no means exceptions. The preferred policy efforts to controlling the flow of illicit trade in gems have been...

As tradeable permit programmes mature, two inter-related issues are becoming more critical in creating viable responses to a long-term, highly uncertain environmental problem such as climate change. First, we need to update policies in response to new information; and second, we need to design...

Policy enabling tropical forests to approach their potential contribution to global-climate-change mitigation requires forecasts of land use and carbon storage on a large scale over long periods. In this paper, we present an integrated modeling methodology that addresses these needs. We model...

We conduct an event analysis on OPEC quota announcements to determine their impact on the stock returns in the oil industry. We find that announcements to reduce the quota are followed by positive excess returns over pre-announcement levels, announcements of no action are met with negative...

This paper tests and confirms the hypothesis that retail and wholesale Diesel 2 prices respond more quickly to increases than to decreases in wholesale and crude oil prices, respectively. Among the possible sources of this asymmetry, we find: production / inventory adjustment lags, refining...

This study provides an empirical analysis of the extent to which ongoing technological change has offset the effect of ongoing depletion on the cost of finding additional reserves of natural gas. In the process, we develop a new index of technological change for exploration and development (E&D)...

This paper examines the efficiency implications of regulated demand price of 93 octane petrol relative to OPEC crude oil price across 183 Namibian localities in 1991. It describes briefly pricing problems associated with managing petroleum and petro-products. Assuming that demand price depends...

The United Kingdom began deregulating its electric market years before the U.S. Thus, the UK provides the best example of what can be expected in the deregulated residential retail electric market in the United States. . An extensive review of the evidence found: Questionable price savings:...

China’s growing demand for oil is significantly changing the international geopolitics of energy, especially in the Asian Pacific region. The recent growth in oil consumption, combined with forecasts of increased oil imports (especially from the Middle East), have led to deep concern among...

Sharp price fluctuations and increasing environmental and distributional concerns, among other issues, have led to a renewed academic interest in energy demand. In this paper we estimate, for the first time in Spain, an energy demand system with household microdata. In doing so, we tackle...
