In this paper, we analyze the effect of reducing import tariffs on intermediate inputs and final goods on the wage skill premium within firms in Indonesia – a country with a high share of unskilled workers. We present a new finding that reducing input tariffs reduces the wage skill premium...

This paper reviews the empirical evidence on firm heterogeneity in international trade. A first wave of empirical findings from micro data on plants and firms proposed challenges for existing models of international trade and inspired the development of new theories emphasizing firm...

I survey the influence of Grossman and Hart's (1986) seminal paper in the field of International Trade. I discuss the implementation of the theory in open-economy environments and its implications for the international organization of production and the structure of international trade flows. I...

This paper reviews the new approach to international trade based on firm heterogeneity in differentiated product markets. This approach explains a variety of features exhibited in disaggregated trade data, including the higher productivity of exporters relative to non-exporters, within-industry...

Empirical studies of firms within industries consistently report substantial heterogeneity in measures of performance such as size and productivity. This paper explores the consequences of joint heterogeneity on the supply side (sellers) and the demand side (buyers) in international trade using...

This paper examines the interdependence between innovation and imports of intermediates, and their joint impact on productivity. We do so by developing a quantitative model with heterogeneous firms and international trade where firms can invest in R&D and source inputs internationally....

This paper estimates the effects of trade liberalization on plant productivity. In contrast to previous studies, we distinguish between productivity gains arising from lower tariffs on final goods relative to those on intermediate inputs. Lower output tariffs can produce productivity gains by...

How does trade liberalization affect wages? This is the first paper to consider in theory and data how the impact of final and intermediate input tariff cuts on workers’ wages varies with the global engagement of their firm. Our model predicts that a fall in output tariffs lowers wages at...

This paper develops a structural empirical general equilibrium model of aggregate bilateral trade with path dependence of country-pair level exporter status. Such path dependence is motivated through informational costs about serving a foreign market for first-time entry of (firms in) an export...

We generalize Krugman's (1979) 'new trade' model by allowing for an explicit production chain in which a range of tasks is performed sequentially by a number of specialized teams. We demonstrate that an increase in market size induces a deeper division of labor among these teams which leads to...
