G-Cubed is a multi-country, multi-sector, intertemporal general equilibrium model that has been used to study a variety of policies in the areas of environmental regulation, tax reform, monetary and fiscal policy, and international trade. It is designed to bridge the gaps between three areas of...

We describe the progress of computable general equilibrium (CGE) modeling software since the 1980s and contrast the main systems used today: GAMS, MPSGE and GEMPACK. The development of these general-purpose modeling systems has underpinned rapid growth in the use of CGE models, and allowed...

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,...

This chapter considers alternatives to the Armington formulation of international trade found in most computable general equilibrium (CGE) models. International trade structures consistent with the monopolistic competition models suggested by Krugman (1980) and Melitz (2003) are presented in a...

Validity is a key issue for consumers of computable general equilibrium (CGE) modeling services. What assurance can producers of CGE results give to consumers that a CGE analysis: (i) is computationally sound, (ii) uses accurate up-to-date data, (iii) adequately captures behavioral and...

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...

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....

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 reviews options of labor market modeling in a computable general equilibrium framework. On the labor supply side, two principal modeling options are distinguished and discussed: aggregated, representative households and microsimulation based on individual household data. On the...

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...
