Products produced by a multiproduct firm can be linked through demand linkages or supply linkages. On the demand side, changes in the price of one product can affect the demand for a firm's other products through shifts in consumer expenditures. This is commonly referred to as the...

New empirical and theoretical work has highlighted the importance of multi-product firms in international tradeflows. We examine multi-product exporters in the small open economy of Belgium, considering their importance and the relationship between the margins of trade and firm productivity,...

This paper studies the impact of market power on international commodity prices. I use a standard oligopoly model and exploit historical variations in the structure of the international coffee bean market to assess the impact of a cartel treaty on coffee prices and its global welfare...

This paper estimates a dynamic general equilibrium model of entry, exit, and endogenous productivity growth. Productivity is endogenous both at the industry level (firms enter and exit) and at the firm level (firms invest in productivity-enhancing activities). The focus of the paper is on two...

This paper investigates whether and how import competition affects firm innovation. Using China’s World Trade Organization (WTO) accession as a quasi-natural experiment, we find that import competition reduces firm innovation, which is consistent with the Schumpeterian effect. We also find...

This paper examine multi-product exporters in Belgium, considering their importance and the relationship between the margins of trade and firm productivity. We employ proxies for trade costs to quantify the extensive and intensive margin adjustments of trade. Relatively few exporting firms...

In this paper, we show that there exists a special breed of firms that are active in both ordinary and processing exports. Contrary to the existing literature that describes processing firms as inferior, these mixed firms are superior to other firms in multiple dimensions, and hence we call them...

This paper studies the distributional costs to US consumers of country-specific tariffs. By linking detailed household purchase records with a barcode-specific country-of-origin, I estimate a demand model with both detailed consumer heterogeneity and rich import substitution patterns in the face...
