Defence Economics uses the tools of economics to analyse and understand defence policy choices and trade-offs.
As the world undergoes a major power transition and a return to inter-state wars and threats of war, defence budgets and cross-border arms transfers have greatly increased for many nations. At the same time, disruptive technologies such as AI are transforming not only civilian economies but also military affairs and defence industries. As states grapple with these challenges, they face trade-offs – from the overall budget allocation to defence to specific procurement or industrial support decisions – that require rational decision making. The discipline of economics was essentially designed to study choices in the face of complex sets of qualitative and quantitative data, and hence the field of Defence Economics provides a unique contribution to making sense of contemporary defence policy making.

Online learning activities: /
Reading and Preparation for Class: 4 hours a week / 48 hours a semester
Research and Preparation for Group Work: 4 hours a week / 48 hours a semester
Research and Writing for Individual Assessments:
Basic concepts in economics and statistics. Reminders will be given for each concept used.
Spring 2025-2026
Two formal exams in a supervised setting.
An interim exam that will test for basic skills based on the first 6 sessions (defence budget data; drivers of defence spending levels; patterns in the international arms trade), with multiple-choice questions.
A final exam that will test for a wider range of analytical skills, where students should demonstrate the ability to apply economic reasoning to complex defence policy problem statements.
The interim exam will account for 35% of the final grade.
The final exam will account for 65% of the final grade.
Exam conditions: Computer-based, but without access to the internet nor to any AI tools. Students would be allowed to bring in a single A4 sheet of paper containing printed or handwritten reminders of the material covered in the course. (E.g., how to interpret a table of statistical results; how to compute the effect of inflation; bullet point summaries of selected themes). Computer setup should allow students to use MS Excel or an equivalent application.
