摘要:We develop a model of assignment games with pairwise-identitydependentexternalities. A concept of conjectural equilibrium is proposed,and the universal conjecture is shown to be the necessary andsucient condition for the general existence of equilibrium. We thenapply the solution concept to a matching-based Cournot model inwhich the unit production cost of a rm depends on both the technologyof the rm and the human capital of the manager hired, andshow that if technology and human capital are complementary, thepositive assortative matching (PAM) is a stable matching under rationalexpectations, or even if rm technology and human capital aresubstitutable yet the substitutive eect is dominated by the marginaleects of technology and human capital, the PAM is still a rationalstable matching. However, if the substitutive eect on the unit productioncost is suciently strong or the market demand is sucientlyhigh, the negative assortative matching is a rational stable matching.
