While many studies explain the correlation between firm-level productivity and export status entirely by better firms self-selecting into exporting, a few studies find evidence of reverse causation. Especially in developing or transition economies, exporters seem to improve performance after...

This paper provides a direct test of how fixed export costs and productivity jointly determine firm-level export behavior. Using Chilean data, we construct indices of fixed export costs for each industry-region-year triplet and match them to domestic firms. Our empirical results show that firms...

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 lower tariffs on intermediate inputs. Lower output tariffs can produce productivity...

Many studies have provided evidence that the correlation between firm-level productivity and export status is driven by more productive firms self-selecting into exporting. Nevertheless, a few studies have also found evidence for a reverse channel of causation. Especially in developing or...

We examine import prices paid by direct-sourcing Indian manufacturing firms in the early 2000s using a unique data set that matches firm characteristics with product and source-country trade data, offering a theoretical and empirical extension of Halpern and Koren (2007). We find that import...

This paper uses firm-level data for Mexican exporters to understand how firm-level export decisions shape a country's aggregate exports. The data allows for a characterization of both the crosssectional distribution of Mexican exports, across destinations and across exporting firms, and of the...

This paper investigates how input trade liberalization affects fi rm-level wage inequality between skilled and unskilled labor. A fall in input tariffs generates increased fi rm pro fits, which, in turn, widens wage inequality since skilled labor enjoys a larger proportion of the incremental pro...

This chapter 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,...

We develop a model of international trade with two sources of firm heterogeneity: "productivity" and "caliber". Productivity is modeled as is standard in the literature. Caliber is the ability to produce quality using few fixed inputs. While there is no quality restriction to sell domestically,...

We develop a model of international trade with export quality requirements and two dimensions of rm heterogeneity. In addition to \productivity", rms are also heterogeneous in their \caliber" { the ability to produce quality using fewer xed inputs. Compared to single-attribute models of rm...
