Interactive Models

A list of interactive models I’ve built in JavaScript and R/Shiny, which are available on this website or other websites, in particular on the companion website to our book with Michaël Assous, https://economic-instability.com, where the applications are accompanied by jointly written blog posts.

I have used the interactive ISLM models to explain basic macroeconomic effects (Pigou effect, Keynes effect, Fisher effect, liquidity trap) to students in introductory macroeconomic classes. Pictures can be drawn easily, and shocks added to observe the comparative statics.

Classroom Models

• The Pit Market Experiment
• Ordinary Least Squares Regression
• ISLM and the Aggregate Demand curve
• The ISLM Model
