PI+ is the premier software solution for conducting dynamic macroeconomic impact analysis of public policy. As our flagship model, PI+ specializes in generating realistic year-by-year estimates of the total local, state, and national effects of any specific policy initiative.
Using a wide range of policy variables to represent the policy being evaluated, REMI’s explicit model structure helps the user interpret the forecasted economic and demographic effects. The model can be calibrated to any sub-national area for policy analysis and forecasting, and is available in single- and multi-area configurations. Each calibrated area (or region) has economic and demographic variables to test the effects of any policy on a local economy.
Model simulations estimate comprehensive economic and demographic effects in wide-ranging initiatives, such as: economic impact analysis; policies and programs for economic development, infrastructure, environment, energy and natural resources.
PI+ is used by government agencies (including most U.S. state governments), consulting firms, nonprofit institutions, universities, and public utilities. Articles about the model equations and research findings have been published in professional national journals, including the American Economic Review, The Review of Economic Statistics, the Journal of Regional Science, and the International Regional Science Review.
