We study how the interaction between economic openness and competitive selection affects the effectiveness of employment (and entry) subsidisation. Within a twocountry heterogeneous-firms model with endogenous labour supply, we find that optimal employment subsidies are always positive even...

We show that the composition of imports has important implications for the optimal volatility of the exchange rate. Using input-output data for 25 countries we document substantial differences in the import and non-tradable content of final demand components, and in the role played by imported...

We show that the combination of monopolistic competition and input-output linkages generate what we call an input distortion. The distortion arises because material input prices involve a markup over the social opportunity cost. This has so far escaped attention in the literature addressing...

In this paper, we provide a detailed analysis of a mechanism that distorts production towards too much use of primary factors like labor and too little use of intermediate inputs. The distortion results from two ingredients that are cornerstones of modern quantitative trade theory: monopolistic...

Using a two-sector-two-country model with aggregate scale economies and unionisation, we show that optimal welfare state policy entails positive levels of unemployment benefits under free-trade and capital mobility. In this setting, economic integration does not reduce the revenue raising...
