Traditional computable general equilibrium (CGE) models have ignored uncertainty ─ even when applied to fields such as environmental modeling that are replete with economic uncertainty. In contrast, many control theory models have focused on the effects of uncertainty. Thus marrying the tradition of CGE and control modeling can result in pricequantity models with explicit dynamics and careful t...

Designing efficient policies to slow global warming requires an approach that combines economic tools with relations from the natural sciences. The dynamic integrated climate-economy (DICE) model presented here, an intertemporal general-equilibrium model of economic growth and climate change, can be used to investigate alternative approaches to slowing climate change. Evaluation of five policie...

In 1985, James A. Baker III's “Program for Sustained Growth” proposed a set of economic policy reforms including, inflation stabilization, trade liberalization, greater openness to foreign investment, and privatization, that he believed would lead faster growth in countries then known as the Third World, but now categorized emerging developing economies (EMDEs). A country-specific, time-series ...

sewage stabilization pond is recommended as one of the economical methods for sewage treatment particularly in dry areas of the world and those places which are in shortage of water and income deficit, this method can be used for treatment of sewage in rural areas, small towns and even large cities. sewage stabilization pond system does not require technical equipment and specialists, and efflu...

To construct copper heap leaching structures, a stepped heap of ore is placed over an isolated sloping surface and then washed with sulphuric acid. The isolated bed of such a heap consists of some natural and geosynthetic layers. Shear strength parameters between these layers are low, so they form the possible sliding surfaces of the heaps. Economic and environmental considerations call for stu...
