Labour & employmentDual Coordination Frictions in Application-Based MatchingWhile higher search effort per worker resolves the first friction (reducing empty vacancies), it exacerbates the second friction (increasing double-job offers and candidate loss), causing aggregate matching efficiency to flatten and diminish beyond optimal application thresholds.Expert TheoryLabour & employmentUrn-Ball Matching Function with Elastic Search EffortThe urn-ball functional form micro-founds crowding-out externalities, yielding structural elasticity estimates where increased search intensity of treated workers directly depresses the contact rate per unit of search effort for non-treated workers.Expert TheoryLabour & employmentUrn-Ball Search Coordination FrictionsIncreasing application intensity per worker initially reduces search friction but eventually yields diminishing marginal returns due to severe application clustering, capturing how nonparticipant matching rates drop from 18.2% to 16.0% under full activation ($\tau = 1.0$).Expert Theory
