To analyze the effects of prospective policy changes, sectoral and economy-wide modelers need to begin with baseline estimates of policy induced price distortions. Global trade modelers mostly use the Global Trade Analysis Project (GTAP) protection database, which currently relies heavily on...

This chapter provides an overview of the first two decades of the Global Trade Analysis Project (GTAP) an effort to support a standardized database and computable general equilibrium (CGE) modeling platform for international economic analysis. It characterizes GTAP in four different dimensions:...

We examine the use of dynamic overlapping generations (OLG) computable general equilibrium (CGE) models to analyze the economic effects of tax reforms, using as a paradigm our DiamondZodrow (DZ) model. Such models are especially well-suited to analyzing both the short-run transitional and the...

In this chapter we present a dynamic general equilibrium methodology for evaluating alternative proposals for tax reform. We illustrate this methodology by comparing alternative proposals that would remove barriers to efficient allocation of capital and labor inputs. These proposals are based on...

A key distinguishing characteristic of computable general equilibrium (CGE) modeling in Australia is its orientation to providing inputs to the policy-formation process. Policy makers require detail. They want to be able to identify convincingly which industries, which occupations, which regions...

The point of departure for the study of the impact of energy and environmental policies is the neoclassical theory of economic growth formulated by Cass (1965) and Koopmans (1967). The long-run properties of economic growth models are independent of energy and environmental policies. However,...

Over the past three decades the field of regional computable general equilibrium (CGE) modeling has flourished, growing from a handful of top-down, single-region and low-dimensioned multiregional models, to a mature field, in which output of large-scale general-purpose multiregional CGE models...

In this chapter I explain an innovative modeling approach that incorporates services, foreign direct investment (FDI) and endogenous productivity effects from services. I begin with a small stylized model to help understand the fundamental economics. The model shows that services liberalization...

This chapter reviews the experience of computable general equilibrium (CGE) models from the perspective of how they have, or have not, influenced public policy in developing countries. The paper describes different classes of empirical models from small, stylized to large, multisectoral applied...

This chapter presents MAMS (Maquette for MDG Simulations), a recursive-dynamic CGE model developed at the World Bank for analysis of medium- to long-run country strategies for low- and middle-income countries, including strategies aimed at improving MDG (Millennium Development Goals) outcomes....
