Book Description
The thesis is organized as follows. Chapter 2 contains a survey of the three most in‡fluential models on fi…rm heterogeneity and of the most important empirical work on firrm heterogeneity. The chapter starts with a brief review of the homogeneous productivity imperfect competition literature. Chapter 2 …finishes with a comparison of the three most in‡fluential models of fi…rm heterogeneity and the oligopoly model put forward in the thesis. Chapter 3 addresses exporting uncertainty under heterogeneous popularity. Chapter 4 contains the chapter on …firm heterogeneity under oligopoly. Chapter 5 constitutes the models on …firm heterogeneity and endogenous quality. Chapter 6 points out the within-sector specialization model. Chapter 7 addresses the effect of importer characteristics on unit values and the role of markups and quality to explain this effect. Chapter 8 concludes.

Book Description
We estimate a structural model of heterogeneous multiproduct firms to examine the sources of firm heterogeneity emphasized in the recent trade and macro literatures. Using Nielsen barcode data on prices and sales, we estimate elasticities of substitution within and between firms, and use the estimated model to recover unobserved qualities, marginal costs and markups. We find that variation in firm quality and product scope explains at least four fifths of the variation in firm sales. Most firms are well approximated by the monopolistic competition benchmark of constant markups, but the largest firms that account for most of aggregate sales depart substantially from this benchmark. Although the output of multiproduct firms is differentiated, cannibalization is quantitatively important for the largest firms. This imperfect substitutability of products within firms, and the fact that larger firms supply more products than smaller firms, implies that standard productivity measures are not independent of demand system assumptions and probably dramatically understate the relative productivity of the largest firms.

Book Description
This paper derives optimal trade and domestic taxes for a small open economy containing a monopolistically competitive (MC) sector in which firms may have heterogeneous productivity levels. Domestic protection brings gains from expanding the number of product varieties on offer, but these gains (and the corresponding rates of domestic subsidy or of import tariffs) are reduced by heterogeneity of foreign exporters who may withdraw from the market. Our analysis encompasses special cases in which the domestic MC sector can expand or contract flexibly, or is of fixed size. In the latter case gains from protection arise from terms of trade effects and, since various margins of substitution are switched off, only the relative values of domestic taxes, import tariffs and export taxes matter
