Through a survey the authors study willingness to pay for improvements in air quality in Sofia, Bulgaria. Using a stochastic payment car approach - asking respondents the likelihood that they would agree to pay a series of prices - they estimate the distribution of willingness to pay various...

Temporary crediting of carbon storage is a proposed instrument that allows entities with emissions reductions obligations to defer some obligations for a fixed period of time. This instrument provides a means of guaranteeing the environmental integrity of a carbon sequestration project. But...

This report looks at the use of a new functional form - the Symmetric Generalized Mcfadden Cost Function (SGM) - to estimate substitutability among metals in five U.S. industries. The SGM specification has the advantage of imposing curvature conditions globally on the cost function, thus...

For 15 years the metals market has been characterized by slow growth - in some cases, even decline - in consumption. To test the proposition that structural changes in demand were the main cause of the slowdown, the author - drawing on U.S. data - uses an extended metals demand model that...

Actual, and potential competition is a powerful source of discipline on the pricing behavior of firms with market power. The authors develop a simple model that shows that the effects of new entry, and import competition on industry price-cost markups, depend on country size. The authors...

The authors report the results of a time-series study of the impact of particulate air pollution on daily mortality in Delhi. They find: a) A positive, significant relationship between particulate pollution and daily nontraumatic deaths as well as deaths from certain causes (respiratory and...

Except for two relatively minor statutes, U.S. environmental laws do not permit the balancing of costs and benefits in setting environmental standards. The Clean Air Act, for example, prohibits the Environmental Protection Agency (EPA) from considering costs in setting ambient air quality...

The authors estimate dose-response functions for respiratory disease among children based on data from public clinics in Santiago. They find that respiratory disease among Santiago s children is significantly affected by air pollution, measured as PM10 (small dust particles). The effect, for...

The point of parallel imports of pharmaceuticals is arbitrage between countries with different prices. For several years, an important issue in the European Union (EU) has been the evident conflict between differing price regulations in the member states, on the one hand, and the consequences of...

Uncertainty is inherent in the analysis of global warming issues. Not only is there considerable scientific uncertainty about the magnitude of global warming, but even if that problem were resolved, there is uncertainty about what monetary value to assign to the costs and benefits of various...
