Questions & Answers

Q: What is the main focus of the content?

The content focuses on a framework that utilizes big data to analyze dynamic multi-country trade models.

Q: What is the significance of the framework discussed?

The framework incorporates realistic input-output linkages, geography, and macroeconomic elements into trade models, allowing for more accurate analysis and representation of trade dynamics.

Q: How does the framework differ from traditional macro models?
