When it is costly for agents to ̄nd a match, integrating small markets into a large one increases the matching di±culty. We examine such dependence of the number of matches on the market size by explicitly modelling ̄rms' attempt to attract workers by posting wages. It is shown that integration reduces the relative market power of agents on the much shorter side of the market. Thus, if there ar...

Any rational pricing phenomenon in the cross section of equity returns must also show up in the corresponding corporate bond returns. We use this powerful insight to investigate whether the equity and corporate bond markets are integrated with respect to risk premia associated with anomalies. We find that the two markets are not integrated through factors suggested by structural credit risk mod...

Recent supply shocks in the Gulf of Mexico—including hurricanes, the Deepwater Horizon oil spill, and the seasonal appearance of a large dead zone of low oxygen water (hypoxia)—have raised concerns about the economic viability of the U.S. shrimp fishery. The ability for U.S. shrimpers to mediate supply shocks through increased prices hinges on the degree of market integration, both among shrimp...

We consider a two-country model of wage determination with private information in unionized, imperfectly competitive, industries. We investigate the effects of opening up markets to trade as well as of further market integration on the negotiated wage and the maximum delay in reaching an agreement. From an initial situation of two-way intraindustry trade, an increase in product market integrati...
