题目：Sorting in Decentralized Markets with Multilateral Contacts

语言：英语

摘要：

This paper derives a number of new results on sorting in markets with frictions. When multiple workers can simultaneously contact a firm, two new issues arise. (i) Stronger  complementarities in the production technology are needed for positive assortative matching than in \citet{EeckKirc10Root} who focus on bilateral meetings. This is because high worker types want to avoid queues with other high types. (ii) A distinction must be made between sorting in contacts and sorting in matches. We derive a class of meeting technologies for which log supermodularity  is sufficient for positive assortative matching and contacting and for which submodular production functions imply negative assortative matching and contacting.
