Self-fulfilling early-contracting rush

In markets for entry-level professionals, the insurance motive drives some participants to sign early contracts. The rush to early contracting can be self-fulfilling, as both its effect on expectations about demand-supply balance in the subsequent spot market and the effect on it from changes in the demand-supply balance can be nonmonotone. Matching markets with more risk-averse participants, a greater uncertainty regarding relative supply of positions, or a more polarized distribution of applicant qualities are more vulnerable to self-fulfilling early-contracting rushes. Employers can have a collective interest in preventing early offers to a few promising applicants from starting the rushes.
