演講摘要 : Agglomeration can be caused by asymmetric information and a locational signaling effect: The location choice of workers signals their productivity to potential employers. The cost of a signal is the cost of housing at that location. When workers' marginal willingness to pay for housing is negatively correlated with their productivity, only the core-periphery (partially stratified) equilibria are stable. When workers' marginal willingness to pay for housing and their productivity are positively correlated, there is no core-periphery equilibrium. The urban wage premium is explained when there is a core-periphery equilibrium. Furthermore, location can at best be an approximate rather than a precise sieve for high-skill workers.
