Course Description

Some basic math techniques are crucial for a proper understanding of the current economic theory and methods, which also applies to agricultural economics.

This course is designed to help graduate-level students at the University of Göttingen and the Doctoral Certificate Program in Agricultural Economics understand some basic math tools (mainly optimization techniques) and their application to resource and environmental economics.
