Abstract We examine how Chinese exporters adjust their number of exported varieties with respect to different characteristics of destination countries and varying trade cost. Using the Chinese firm-level customs data from the years 2001 and 2006, we show that: (i) firms export fewer varieties...

We model an oligopoly where firms can choose the quality level of their products by incurring set-up costs that generally depend on quality level. If the set-up cost is independent of product quality, firms may choose to supply both types of quality.We focus on the long run equilibrium where...

The rise of market power and the decline of labor's share of GDP in the United States in recent decades is well documented and have critical macroeconomic implications, but the determinants of such trends remain unclear. This paper asks how and to what degree increasing import penetration...

The importing country usually imposes heterogeneous import tariff rates based on the national origins of the products. Reducing the tariff rates on the products from one origin country not only increases the import flows from this country, but also decreases the import flows from the other trade...

The rise of market power in recent decades has received increased attention, but the determinants of such a rise remain unclear. This paper studies whether and how increasing import penetration of inputs leads to a more concentrated market structure and the associated rise of markups. The use of...

The effect of exchange rate movement on trade has been studied widely for a long history. Most literatures focus on its impacts on firms' export performances, and the performances usually refer to the intensive and extensive margins of export. Adding to the existing studies, we explore how firms...
