DREAM is a partial equilibrium, single commodity, multi-region, economic surplus model for assessing the potential economic benefits of technology diffusion and adoption (including technology spillover). Users can simulate a range of market, technology generation and adoption, research spillover, and trade scenarios, and explore the potential benefits (and losses) of technical change by geographic and socio-economic groupings.

The model code, tools, and documentation are available from IFPRI Dataverse. Please click Launch to download.
