Quality change in price indexes

Article Abstract:

The Consumer Price Index (CPI) fails to account for changes in the quality of products and the consequent improvement in the quality of lives of purchasers of these products. Aside from these, the CPI also does not reflect price shifts caused by the introduction of new products, modifications in delivery of health services, and major technological innovations. As the CPI handles data for hundreds of thousands of commodities and services, the only feasible alternative is to limit the calculations to selected items.

Lethal model 2: the limits to growth revisited

Article Abstract:

The limits-to-growth (LTG) economic debate and model as described in the study entitled 'The Limits to Growth' is analyzed. Results show that while slower economic growth is visualized for the future, the complex LTG computer models Limits I and Limits 2 are unduly pessimistic, fail to account for ongoing technological change and are based on invented equations. Implications for government economic policy inthis analysis include environmental and regulatory issues.

Optimal greenhouse-gas reductions and tax policy in the "DICE" model

Article Abstract:

Scientists must deal with problems such as uncertainty and modeling when developing optimal policies for controlling greenhouse gases (GHG). The use of 'carbon taxes' in reducing emissions of GHGs and the analysis of the cost-effectiveness of policies are becoming more popular. The dynamic integrated climate-economy (DICE) model attempts to reduce GHG emissions by considering emissions, the economic costs of policies and the effects of climate change.
