Public Debt, Investment, and Growth: The DIG and DIGNAR Models from edX

Over the past decade, the DIG and DIGNAR models have gained wide acceptance for policy work. They have complemented the analyses done with the IMF and World Bank Debt Sustainability Framework, with over 65 country applications in the context of Fund-supported programs and surveillance work. They have helped inform policy analysis, based on qualitative and quantitative scenario analyses, on issues not only related to public investment surges but also to fiscal consolidations, cash transfers to poor households, the mix of public current and capital expenditures, the efficiency of public spending and tax administration, and the collapse of commodity prices, among others. The course will illustrate some of these applications and explain how to interpret the output of these policy scenario analyses.

What you'll learn

Upon completion of this course, participants should be able to:

Understand the basics of dynamic macroeconomic models for analyzing public investment scale-ups, growth, and debt dynamics.
Understand the key elements of the DIG and the DIGNAR models.
Understand how these models are used to analyze how the macroeconomic effects of public investment surges depend on policy responses, type of financing of these surges (e.g., taxes and domestic versus external financing), and structural factors (e.g., the efficiency of public investment).
Interpret the output of policy scenario analyses using the DIG and DIGNAR models, as reflected in official IMF documents such as Art. IV reports.

Reviews summary

Macroeconomics and policy course

Learners say this course offers in-depth macroeconomics and policy knowledge by using simulations and charts to explain key concepts. Economic jargons were well explained throughout the material, while the course covered a range of topics such as the effects of public investment on growth and public debt, and how to read simulation results. However, some learners noted that the course could improve by having more discussion on the forum.

Instructors did an excellent job of explaining material without using complex language.

"The instructors did an excellent work in presenting the material without relying on advanced mathematics."

"Economic jargons were also well explained in the context using plain English."

Course uses simulations and charts to help understand complex concepts.

"This excellent course taught the interaction between macroeconomics and policy, by using simulations."

Course lacks engagement due to limited forum discussion.

"One of the problems with the course was the limited discussion on the forum."
