MAMS: A Tool for Country Strategy Analysis


The World Bank's Development Prospects Group has developed a tool for economy-wide, country-level analysis of medium- and long-run development policies, including strategies for reducing poverty and achieving the Millennium Development Goals (MDGs). The tool – named MAMS (Maquette for MDG Simulations) – is a dynamic Computable General Equilibrium model that has been extended to cover the generation of outcomes in terms of growth, MDGs, and the educational make-up of the labor force, as well as the interaction of these outcomes with other aspects of economic performance.

The government policies that are considered include:

  • spending: its level and allocation across different areas (including education, health, and infrastructure);
  • financing: policies for taxation, domestic and foreign borrowing, and foreign aid.

Economic performance is measured by the evolution of:

  • poverty and other MDG targets;
  • macro indicators: GDP (split into private and government consumption and investment; exports; imports); the composition of the government budget, the balance of payments, and the savings-investment balance; total factor productivity; and domestic and foreign debt stocks.
  • sectoral structure of production, employment, incomes, and trade;
  • the labor market: unemployment; educational composition of the labor force.

MAMS is a flexible tool that can be run in different versions that differ in data needs. For example, for analysis of macro issues, it is sufficient to use a version with minimal data needs; analysis of MDG strategies requires a version with additional sectoral disaggregation and a more detailed database.
