Bargaining with Surplus Destruction

Lutz-Alexander Bush, Shouyong Shi, Quan Wen

In a two-player alternating-offer bargaining model, if one player can destroy the surplus to be allocated, then the value to bargain for is endogenous, except at the beginning. Even with complete...

Coordination, matching, and wages

Melanie Cao, Shouyong Shi

We analyse the coordination problem in the labour market by endogenizing the matching function and the wage share. Each firm posts a wage to maximize the expected profit, anticipating how the wage...
