DREAMpy

Dynamic Research EvaluAtion for Management

python version 2.2

Open source, user-friendly software for evaluating the economic impacts of agricultural research and development projects.

What you need to know

DREAMpy is an open source software for evaluating the economic impacts of agricultural research and development projects. Based on a flexible, multimarket, partial equilibrium model, DREAMpy handles simple to relatively complex evaluation problems using user-friendly Excel worksheets.

 

Additionally, it also allows users to run sensitivity analysis of critical variables through repeated simulations.


Users can define a range of technology investment, development, and adoption scenarios, and can simulate a range of scenarios for:

  • markets
  • technology adoption
  • research spillover
  • trade policy

Scenarios are described using information for any number of separate country-specific regions, countries, or trading regions. Factors such as taxes, subsidies, growth rates, and price elasticities can be specified as constant or as changing over the analysis period. Users can simulate likely effects of technology development and adoption on prices; on quantities produced, consumed, and traded; and on the flow of economic benefits.

 

The software also accommodates technology-driven shifts in supply or demand, and users can specify constant or variable shift effects over time in farmers’ fields.
