Book Description
A recent theoretical literature has emphasized the importance of multiproduct firms in trade. However, models within this literature have reached contradictory conclusions regarding the product-level response of firms to changes in trade costs. This paper attempts to resolve these contradictions by employing Bayesian techniques to estimate the product portfolio response throughout the distribution of U.S. firms following the Canada-US Free Trade Agreement of 1989. I find evidence of a differential response among firms that are heterogeneous in terms of their involvement in foreign markets. Firms with less than 10-20 percent of total sales accounted for by foreign markets reduced product diversification as trade costs fell, while more foreign-oriented firms increased diversification.

Book Description
In this paper we develop a monopolistic competition model where firms exercise their market power across multiple products. Even with CES preferences, markups are endogenous. Firms choose their optimal product scope by balancing the net profits from a new variety against the costs of "cannibalizing" their own sales. With identical costs across firms, opening trade leads to fewer firms surviving in each country but more varieties produced by each of those firms. With heterogeneous costs, the number of firms surviving in equilibrium is quite insensitive to the market size. When trade is opened, more firms initially enter, but the larger market size reduces the cannibalization effect and expands the optimal scope of products. As a result, the less efficient firms exit, and the larger market is accommodated by more efficient firms that produce more varieties per firm on average.

Book Description
This paper develops a general equilibrium model of multi-product firms and analyzes their behavior during trade liberalization. Firm productivity in a given product is modeled as a combination of firm-level "ability" and firm-product-level "expertise", both of which are stochastic and unknown prior to the firm's payment of a sunk cost of entry. Higher firm-level ability raises a firm's productivity across all products, which induces a positive correlation between a firm's intensive (output per product) and extensive (number of products) margins. Trade liberalization fosters productivity growth within and across firms and in aggregate by inducing firms to shed marginally productive products and forcing the lowest-productivity firms to exit. Though exporters produce a smaller range of products after liberalization, they increase the share of products sold abroad as well as exports per product. All of these adjustments are shown to be relatively more pronounced in countries' comparative advantage industries.

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
Product scope adjustment is a key mechanism through which multi-product firms achieve efficient resource allocations. In this paper, we take a novel perspective to study firms’ product scope adjustment behavior through the lens of asset pricing. Using a unique panel scanner data set containing detailed information on products, matched with the financial information of their manufacturers, we find that multi-product firms with higher product turnover have lower financial risks and lower risk premia. To understand this channel, we propose a stylized model with a time-dependent (Calvo-type) product turnover rate to highlight the ’risk absorption channel’ of product scope adjustment. In response to an economy-wide shock, a firm that can adjust its product scope more flexibly shows lower excess equity returns and lower asset volatility.

Book Description
Presents a new research program that is transforming the study of international trade. Until a few years ago, models of international trade did not recognize the heterogeneity of firms and exporters, and could not provide good explanations of international production networks. Now such models exist and are explored in this volume.

Book Description
Recent theoretical work predicts that an important margin of adjustment to deregulation or trade reforms is the reallocation of output within firms through changes in their product mix. Empirical work has accordingly shifted its focus towards multi-product firms and their product mix decisions. Existing studies have however focused exclusively on the U.S. Using detailed firm-level data from India, we provide the first evidence on the patterns of multi-product firm production in a large developing country during a period (1989-2003) that spans large-scale trade and other market reforms. We find that in the cross-section, multi-product firms in India look remarkably similar to their U.S. counterparts, confirming the predictions of recent theoretical models. The time-series patterns however exhibit important differences. In contrast to evidence from the U.S., product churning--particularly product rationalization--is far less common in India. We thus find little evidence of "creative destruction". We also find no link between declines in tariffs on final goods induced by India's 1991 trade reform and product dropping. The lack of product dropping is consistent with the role of industrial regulation in India, which, like in many other developing countries, may prevent an efficient allocation of resources.

Book Description
We present a new model of multi-product firms (MPFs) and flexible manufacturing, and explore its implications in partial and general oligopolistic equilibrium. Globalization affects the scale and scope (or intensive margin and intra-firm extensive margin) of MPFs through a competition effect and a demand effect. The model highlights a new source of gains from trade: productivity increases as firms become "leaner and meaner", concentrating on their core competence; but also a new source of losses from trade: product variety may fall. Our results also hold under free entry, which allows in addition for adjustment along the traditional inter-firm extensive margin.
