We analyze the cost-effectiveness of electric utility rate payer–funded programs to promote demand-side management (DSM) and energy efficiency investments. We develop a conceptual model that relates demand growth rates to accumulated average DSM capital per customer and changes in energy prices, income, and weather. We estimate that model using nonlinear least squares for two different utility ...

Method: Building a document ranking system involves two key decisions: choosing a retrieval model, and choosing a suitable index representation. The former determines the effectiveness of the system, the latter the efficiency; and each of them affects the other. The impact-based document ranking mechanism described by Anh and Moffat [2] was chosen for our system because of its balance between e...

To gain analytical insight into whether input resources matter in public education, a Becker/Peltzman/Stigler model of the determination of local educational budgets and outputs by political authorities is constructed. The model results are consistent with empirical findings that resources don’t matter, even when all schools are efficient, if errors in measurement and specification occur. When ...
