Frictional Matching Models, along with Sorting through Search and Matching Models in Economics, constitutes the self-contained lecture notes on search and match.It contains many new or unified proofs using monotone comparative statics.


Abstract: Toward understanding assortative matching, this is a self-contained introduction to research on search and matching. We first explore the nontransferable and perfectly transferable utility matching paradigms, and then a unifying imperfectly transferable utility matching model. Motivated by some unrealistic predictions of frictionless matching, we flesh out the foundational economics of search theory. We then revisit the original matching paradigms with search frictions. We finally allow informational frictions that often arise, such as in college-student sorting.
