Using varieties of a rich model that considers sectoral heterogeneity and input-output linkages, this paper shows that the overall welfare gains of a region within a country can be decomposed into domestic versus international welfare gains from trade. Empirical results based on state-level data...

This paper develops a general-equilibrium model which features the Home Market Effect and land use for production in the sector of increasing returns to scale. The land rent in the larger region is higher, meanwhile, the larger region holds more-than-proportionate share of firms, the so called...

In a framework of a unionised international Bertrand duopoly with differentiated products, this paper analyses national labour market interdependencies and the consequences of trade liberalisation for union wages. The analysis suggests that national wages are likely to be strategic complements...

Recent empirical evidence suggests that prices for some goods and services are higher in larger markets. This paper provides a demand-side explanation for this phenomenon when firms can choose how much to differentiate their products in a model of monopolistic competition with horizontal product...

This paper sets up a general oligopolistic equilibrium model with unionized labor markets. By accounting for productivity differences, the model features pro t and wage differentials across industries. We use this setting to study the impact of trade liberalization on employment, welfare, and...

We study the profitability incentives of merger and the endogenous industry structure in a strategic trade policy environment. Merger changes the strategic trade policy equlilibrium. We show that merger can be profitable and welfare enhancing here, even though it would not be profitable in a...
