This paper provides evidence on the monopolistic competition model with heterogeneous firms and endogenous productivity. We show that this model has a well-defined GDP function where relative export variety enters positively, and estimate this function over 48 countries from 1980 to 2000....

For both primal and dual TFP growth accounting to properly account for productivity growth, assumptions of constant returns to scale and perfect competition are necessary. This paper shows that without these assumptions, while both TFP growth accounting measures remain equal if factor shares are...

This paper builds a tractable partial equilibrium model to help explain the role of trade preferences given to developing countries, as well as the efficacy of various subsidy policies. The model allows for firm level heterogeneity in demand and productivity and lets the mass of firms that enter...

Trade liberalizations have been shown to improve domestic firms' performance through the new varieties of imported intermediate inputs. This paper uses a unique, representative sample of Bangladeshi garment firms to highlight that local intermediate inputs may also enhance domestic firms'...

The economic successes of China and India are viewed with admiration but also with concern because of the effects that the growth of these Asian economies may have on the Latin American and Caribbean (LAC) region. The evidence in 'China's and India's Challenge to Latin America' indicates that...

This paper quantifies trade policy changes and the associated trade impacts for about 100 countries between 2008 and 2009. Results show that there has been no widespread increase in protectionism. Only a few countries, including Russia, Argentina, Turkey, and China, have increased tariffs on...

This paper provides a new heterogeneous firm model for trade where firms differ in their productivity and experience different market demand shocks. The model incorporates the variations in trade policy, trade preferences, and the rules of origin needed to obtain them that are faced by...
