Aggregate exports are not very responsive to real exchange rates, though they respond strongly to trade liberalizations, a fact sometimes referred to as the International Elasticity Puzzle. We use micro data on firms and exports for Ireland to dissect the puzzle. Our identification strategy uses...

We document how export quantities and prices evolve after entry to a market. Controlling for marginal cost, and taking account of selection on idiosyncratic demand, there are economically and statistically significant dynamics of quantities, but no dynamics of prices. To match these facts, we...

We show that in successful episodes of export market entry, there are statistically and economically significant post-entry dynamics of quantities, but no post-entry dynamics of markups. This suggests that shifts in demand play an important role in successful entry, but that firms do not use...

Multinational affiliates are more productive than domestic firms, so how do they affect a host country through the labor market? We use data for Norway to show that the labor market is characterized by a job ladder, with multinationals on the upper rungs. We calibrate a general equilibrium job...

We use comparable micro level panel data for 14 countries and a set of identically specified empirical models to investigate the relationship between exports and productivity. Our overall results are in line with the big picture that is by now familiar from the literature: Exporters are more...

We examine the determinants of firm’s current environmental expenditure and firm’s capital investment in equipment for pollution control using a Heckman selection model. As regards current environmental expenditure, we find that larger, exporting firms and firms subject to the Integrated...
