### Course Description

The course learning objectives address both conceptual and methodological issues of deterministic approaches of efficiency and productivity measurement. Data envelopment analysis (DEA) is the methodological core of the course. This non-parametric approach uses empirical data to determine a frontier representing the best practice as a basis for measuring inefficiency. DEA bridges the gap between theory and practice. To accomplish this objective, theoretical and methodological sessions will be followed by examples of empirical applications in agriculture and practical exercises. Upon completion of this course, students will understand the underlying theory and become familiar with the software to initiate their own research project using parametric approaches to modeling efficiency and productivity.

This course on deterministic approaches to efficiency measurement can be complemented by a course on parametric approaches. Both courses comprise 5 days of teaching. Students may enroll for either the deterministic or the parametric course, or both. Students are encouraged to take both parts, although each part is independent.

### Grading

Participants will work on an assignment applying efficiency and productivity concepts presented in the course to a given data set. Details of the composition of the assignment will be distributed to participants on the last day of the course. The assignment will be due six weeks after the course end and will be sent to the instructors by email.
