This paper builds a tractable partial equilibrium model in the spirit of Melitz (2003), which incorporates two dimensions of heterogeneity: firms specific productivity shocks and firm-market specific demand shocks. The structural parameters of interest are estimated using only cross-sectional...

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...

There is little work on the inner workings of journals. What factors seem to affect the ability to publish in a journal? Could simple rules (which are already used by some journals) like the desk rejection of a significant minority of papers, help to streamline the process? At what cost? How...

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 variations in trade policy, trade preferences, and the rules of origin needed to obtain them, to reflect real world...

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...

In this paper we use the monopolistic competition model with heterogeneous firms to study the effect of different policies on productivity and welfare, and provide three particular policies, which allow to reach the first best allocation in the economy. We also show that an export subsidy...

There is little work on the inner workings of journals. What factors seem to affect the ability to publish in a journal? Could simple rules (which are already used by some journals) like the immediate rejection of a significant minority of papers, help to streamline the process? At what cost?...

This paper shows that the results of Venables (1987) depend critically on the assumption that there are no fixed costs of trade. The introduction of fixed costs of exporting, while making the model more consistent with the empirical evidence, leads to the opposite conclusion that technological...

This paper shows that the result of Ju and Krishna (2002, 2005), i.e., the non-monotonicity in the comparative statics across regimes, disappears, if exporters differ in their productivities, which provides very different predictions about the results of policy changes.
