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

Public debt models: practical policy application

According to students, this course offers an incredibly practical and invaluable understanding of the DIG and DIGNAR models, which are widely used in policy work. Learners praise its clear explanations of complex topics and its direct relevance to real-world policy analysis, particularly in interpreting official IMF documents and applying insights to public finance. Many find it an indispensable resource for professionals in macroeconomic policy and government. However, some learners caution that the course assumes a strong background in macroeconomics, with discussions sometimes feeling dense or rushed for those without prior advanced quantitative knowledge. A few also noted a lack of interactive exercises, suggesting it's more about interpretation than building models from scratch.

Focuses on a specific and niche area of economic modeling.

"Highly specialized but incredibly valuable. If you're involved in public finance or macroeconomic policy, this is a must-take."

"It's not a general macro course, so come prepared with relevant background."

"I believe it's geared towards a very niche audience, making it inaccessible for others."

Models are presented clearly and in an understandable way.

"The DIG and DIGNAR models were explained thoroughly... The instructors did an excellent job of distilling complex topics into understandable segments."

"Excellent coverage of the models and their real-world use. The examples were perfect for understanding the nuances."

"The practical implications derived from the DIG and DIGNAR models are clearly demonstrated. Very pleased with the depth and clarity."

Provides highly relevant and practical insights for policy analysis.

"This course was exactly what I needed for my role in the Ministry of Finance. The focus on policy scenario analysis using real IMF documents was incredibly practical."

"The insights into how public investment surges affect growth under different policy regimes were invaluable. I learned a lot about interpreting official IMF reports."

"As an economist working on fiscal policy, this course was a game-changer. It perfectly bridges theory and practice."

Concentrates on model output interpretation, less on hands-on creation.

"It's good for interpretation but less so for building the models from scratch. Needs clearer pacing."

"Disappointed by the lack of hands-on application. It's mostly theoretical and interpreting existing outputs, not building models myself."

"The course is very lecture-heavy and could benefit from more interactive elements or problem sets to apply the concepts myself."

Assumes a strong background in advanced macroeconomics.

"I struggled with this course. It felt like it assumed a very high level of prior knowledge, particularly in quantitative macroeconomics."

"While the content is strong... I sometimes felt the theoretical underpinnings could have been expanded upon more. It assumes a solid background in macroeconomics."

"A bit challenging if you're rusty on your macro, but worth the effort."
