Comparative Statics, tracking an optimal or equilibrium value as an exogenous variable changes, ceteris paribus, is the heart of economic analysis. By building models and analyzing the comparative ...

We elucidate a powerful yet simple method for deriving comparative statics conclusions for a wide variety of models: Monotone Comparative Statics (Milgrom and Shannon 1994). Monotone comparative ...

Here, we give a new proof of the entry comparative static, by way of a well-known property of deferred acceptance called respect for improvements. Our argument extends to yield comparative static ...

The Comparative Statics Wizard is an Excel add-in that walks the user through a series of steps in order to conduct comparative statics analysis. The files below use the Comparative Statics Wizard.

We define and explore the No-Upward-Crossing (NUC), a condition satisfied by every parameterized family of distributions commonly used in economic applications. Under smoothness assumptions, NUC is ...

This paper studies comparative statics in the consumer utlity maximization problem with two goods. The analysis can be global, and it allows for indivisibilities, discrete changes, and non-binding ...

We prove a natural comparative static for many-to-many matching markets in which agents’ choice functions exhibit size-dependent discounts: reducing the extent to which some agent discounts additional ...
