Lesson 10 introduces users to the programming of Mixed Complementarity Problems (MCPs) where a program consists of inequality constraints that are complementary to one another. This final lesson of the AGRODEP GAMS training assumes familiarity with economic modeling. The model presented here is similar to the model in Lesson 8. In this lesson, however, it assumes a minimum wage that could be binding and therefore includes possible unemployment in the model solution. GAMS code in this lesson is partially based on the McCarl GAMS User Guide.
