The ability of consumers to make rational sequential purchase quantity decisions under imperfect ... more The ability of consumers to make rational sequential purchase quantity decisions under imperfect knowledge about future prices in a product category is explored. Normatively, a consumer should make such decisions by defining a series of reservation prices which define how many buying-periods' supply should be held given an observed price. An experiment is reported in which consumers make sequential purchase quantity decisions under variations in the shape of the distribution of prices and its trend over time. Results suggest a number of systematic deviations from optimality. When facing stationary uniform and bimodal price distributions, for example, subjects tend to systematically overbuy when small purchases are called for and underbuy when large purchases are called for. Likewise, when facing ascending or descending series, behavior is the opposite of that predicted by the normative analysis: there is an increasing tendency to defer purchases given increasing prices and accel...

Other gaseous emissions from combustion include sulfur oxides, nitrogen oxides, organic compounds, carbon monoxide, particulate matter, mainly in the form of carbon particles (soot), and several metals. Some of these pollutants react in the atmosphere, giving rise to other pollutants like ozone, sulfates, and nitrates.Several non-health impacts from oil (petroleum) combustion emissions have been observed; these effects are represented mainly by acid deposition, effects on vegetation, alteration of atmospheric visibility, increased turbidity of the atmosphere, and damage to materials. All effects have a cost thus there is also an economic effect also, loss of historical memory is also a concern because of damage to important monuments and to historical buildings; there is also a concern over food chain as well as about the effects on animals and aquatic life.This chapter will describe combustion emissions, the main non-health effects caused by oil combustion emissions, and the importance of individual pollutants.
