International Futures (IFs) is a long-term integrated assessment model or system which is a collection of several hard–linked, directly interconnected models (sometimes referred to as modules). It is dynamic recursive with annual time steps to 2100. It represents 186 countries connected through a variety of flows, facilitates aggregation of them to global regions, and allows subdivision of them into more local socio-political units. The IFs system is available for use by others both on-line and in a downloadable version, and it is open source. Major models in IFs (see Figure 1 below) include | |||
• a multistate population model (which represents 22 age sex cohorts to age 100+ and differentiates their educational attainment and cause-specific mortality patterns). | |||
• a multisector general equilibrium economic model (which uses inventories as buffer stocks and to provide price signals so that the model chases equilibrium over time); it provides labor, investment, and consumption information to partial equilibrium energy and agriculture models. | |||
• an education model that tracks grade-by-grade student progression and aging of adults with variable attainment levels. | |||
• a health model that represents age-sex specific mortality and morbidly by 15 causes of death. | |||
• socio-political representations that include governance capacity and finance, wrapping the economic model in a broader social accounting matrix. | |||
• an energy model (which portrays production of six energy types: oil, gas, coal, nuclear, hydroelectric, and other renewable). Physical values from the partial equilibrium model are converted to currency values to replace those in the general equilibrium economic model. | |||
• an agricultural model (which is a partial equilibrium model in which food stocks buffer imbalances between production and consumption and determine price changes); the model represents crop, gazing, forest, developed and other land.

International Futures (IFs) is a long-term integrated assessment model or system which is a collection of several hard–linked, directly interconnected models (sometimes referred to as modules). It is dynamic recursive with annual time steps to 2100. It represents 186 countries connected through a variety of flows, facilitates aggregation of them to global regions, and allows subdivision of them into more local socio-political units. The IFs system is available for use by others both on-line and in a downloadable version, and it is open source. Major models in IFs (see Figure 1 below) include • a multistate population model (which represents 22 age sex cohorts to age 100+ and differentiates their educational attainment and cause-specific mortality patterns). • a multisector general equilibrium economic model (which uses inventories as buffer stocks and to provide price signals so that the model chases equilibrium over time); it provides labor, investment, and consumption information to partial equilibrium energy and agriculture models. • an education model that tracks grade-by-grade student progression and aging of adults with variable attainment levels. • a health model that represents age-sex specific mortality and morbidly by 15 causes of death. • socio-political representations that include governance capacity and finance, wrapping the economic model in a broader social accounting matrix. • an energy model (which portrays production of six energy types: oil, gas, coal, nuclear, hydroelectric, and other renewable).
