Webinar: Flexible demand systems in Stata


Duration: 1 hour
Where: Join us from anywhere!
Cost: Free—but registrations are limited


Interested in estimating demand for a basket of goods? Do you also need price sensitivities measured according to classic economic theory? Demand system models allow you to conduct demand analysis and to understand the interrelationship among products consumers purchase.

Stata 18 introduced the demandsys command to fit eight different demand system models, including the Cobb–Douglas demand system, the almost ideal demand system (AIDS), quadratic AIDS, and more.

In this webinar, we will discuss demand system modeling and show how to fit these models in Stata, consider when to use which model, and demonstrate postestimation tools for computing elasticities to measure the sensitivity of the demand to price and expenditure changes.

How to join

The webinar is free, but you must register to attend. Registrations are limited so register soon.

We will send you an email prior to the start with instructions on how to access the webinar.
