AbstractThis paper addresses welfare effects from trade liberalization in a Melitz () heterogeneous‐firms trade model including the empirically important per‐unit (i.e., additive) trade costs in addition to the conventional iceberg (i.e., multiplicative) and fixed trade costs. The novel contribution of the paper is the result that the welfare gain for a given increase in trade openness is higher for reductions in per‐unit (additive) trade costs than for reductions in iceberg (multiplicative) trade costs. The ranking derives from differences in intra‐industry reallocations and, in particular, from dissimilar impacts on the number of exporters (i.e., the extensive margin of trade).

Abstract Contrary to the prevailing interpretation, this paper shows that the central models of trade with heterogeneous firms (Melitz 2003; Bernard et al. 2003) exhibit ambiguous predictions for the exporter productivity premium. This prospect arises because of differences between theoretical and empirical representations of firm productivity. Instead of marginal productivity, we examine in both models the theoretical equivalent of empirically observable productivity (value‐added per employee). Given the presence of fixed export costs or heterogeneous mark‐ups and trade costs, the observable productivity of exporters in proximity to the export‐indifferent firm turns out to be lower than that of non‐exporters; that is, the productivity distributions overlap. The paper reviews empirical literature that reports non‐positive exporter productivity premia in firm‐level data and discusses implications for empirical research on exporter performance, including learning and the role of non‐parametric regressions (stochastic dominance, quantile regressions), fixed costs, and productivity distributions.

The Nordic welfare model has received a lot of positive attention around the world. High standard of living, small income disparities and substantial social mobility looks like a very attractive package. Moreover, sound public finances and strong emphasis on environmental sustainability suggest that today's success has not been accomplished at the expense of future generations. But is there really a unique "Nordic Supermodel", unshaken by the global economic crisis and capable of producing continuous high growth and world class welfare services when many developed economies struggle with the impacts of global competition and population ageing? This book shows that Nordic performance has not been quite as unique or uniform as often claimed. The recent global and European crisis and country specific shocks have affected also the Nordic countries, some of them very strongly. And there are as many variants of the Nordic model as there are Nordic countries. Going forward, also the Nordic countries will be challenged by ageing, globalisation and technological change, some more than the others. On the other hand many fundamentals remain strong in the Nordic countries, and, what is perhaps most important, the Nordics have proved themselves capable of adjusting. Labour market practices, pension policies, and production of public services have been reformed to match new circumstances. Public policies have been aimed at creating new jobs and helping people in transition, not at protecting uncompetitive businesses. There is a strong, rational tradition of consensual policy making. Further reforms are needed, and some widening of income disparities may be inevitable. The message of the book is, however, that refocused and recalibrated in a realistic scale the Nordic model has good chances of thriving well into the future.
