Kiminori Matsuyama, Professor of Economics at Northwestern University, will be visiting Columbia to host a two-part mini course series on “Homothetic Non-CES Demand Systems with Some Applications.”
Abstract: The CES demand system is widely used as a building block in business cycles theory, economic growth and development, international trade and other general equilibrium fields, because it has many knifeedge properties, which help to keep the analysis tractable in the presence of many goods and factors. However, this also makes it hard to tell which properties of CES are responsible for certain results. Moreover, it is necessary to relax some of them for certain applications. I recently published two review articles (ARE 2023; ARE 2025), which discuss several classes of non-CES aggregators, each of which removes some properties of CES and keeps the rest to introduce some flexibility while retaining the tractability of CES as much as possible. In this mini-lecture series, I will discuss some selected applications of such non-CES demand systems.
