The tools for policy evaluation and analysis reviewed in the preceding chapters are all ex-post, as they essentially compare the distribution of welfare over a population before and after a given policy or a given local program is implemented. While ex-post evaluation is essential for assessing the true impacts of existing policies and programs, there are many instances in which policymakers wo...

Methods of empirical economic analysis have undergone enormous changes in recent decades. The availability of improved statistics and of high-speed computers have facilitated this process, but the increasing ambition and complexity of economic policy itself have perhaps been the major stimuli. In most of the economically advanced countries and, increasingly, in developing countries also, analys...

A multisectoral global model was constructed on a 35 I-O sectoral basis in 1995 and has extensively been used for various policy analyses. The model, EITF, covers 29 countries and 7 regions with special reference to G7 and Asian countries. World trade can also be analyzed in the same sectoral categories, enabling the analysis of significant changes in foreign trade consistent with those for sec...

This paper offers an econometric model system that simultaneously considers six different activity-travel choice dimensions in a unifying framework. The six dimensions include residential location choice, work location choice, auto ownership, commuting distance, commute mode, and number of stops on commute tours. The paper presents the modeling methodology in detail as well as estimation result...

Marketers routinely use timing as a segmentation device through sequential product releases. While there has been much theoretical research on the optimal introduction strategy of sequential releases, there is little empirical research on this problem. This paper develops an econometric model to empirically solve the inter-release timing problem: it involves (1) developing and estimating a stru...

This study introduces methodology to quantify the e¤ects that regulation has on the innovation and the introduction of new products, and compares state-regulated services in Indiana under rate of return regulation (RoRR) and under alternative regulation. The econometric model comprises a count process (for innovation) followed by a duration process with selection (for regulatory delay). When th...

This chapter examines the relationship between growth and inflation in the long-run. Although positive in the short-run, cross-country studies indicate a negative relationship between the two in the longer run. There is now considerable evidence to show that investment is one of the most important determinants of the long-run rate of growth. Recent developments in the theory of investment behav...

This study examines the hypothesis that dairy cow ownership improves child nutritional status. Using household data from coastal and highland Kenya, three econometric model formulations are estimated. Positive impacts on chronic malnutrition are observed for coastal Kenya. No negative effects on acute or chronic malnutrition are found for either region.
