Is the variation in bilateral trade flows across countries primarily due to differences in the number of exporting firms (the extensive margin) or in the average size of an exporter (the intensive margin)? And how does this affect the estimation and quantitative implications of the Melitz (2003)...

The transition into non-traditional export activities attracts important policy and academic attention. Using international trade data, we explore how alternative linkages relate to the take-off and acceleration of export industries. Concretely, we run a horse-race among alternative Marshallian...

This paper develops a model of a monopolistically competitive industry with extensive and intensive business investment and shows how these margins respond to changes in average and marginal corporate tax rates. Intensive investment refers to the size of a firm's capital stock. Extensive...

The underlying model analyzes the first time foreign market entry decision of a representative investor who can choose between export and FDI. The model combines the proximity-concentration trade-off framework with the real option methodology and sheds light on the effects of productivity...

I show in this paper that incomplete contracts affect a firm's decision about serving foreign customers through exports or local sales from an affiliated plant. When contracts between two agents within a firm are too costly to write, the share of multinational firms may be higher or lower...

In this paper, we zoom in on the firm level of German merchandise foreign trade, using a novel data base with information on the export and import value by firm, country, product and year for the period 2011-2019. Problems arising from the consolidated reporting of taxable entities and the...

We provide an overview and synthesis of recent work on models of monopolistic competition with heterogeneous firms in international trade, paying particular attention to competition effects, pass-through, selection effects, and linking distributions of firm characteristics and outcomes. A...

High-performance firms typically have two features in common: i) they produce in more than one country and ii) they produce more than one product. In this paper, we analyze the internationalization strategies of multi-product firms at the product-level. We find that the most productive firms...

We derive exact conditions relating the distributions of firm productivity, sales, output, and markups to the form of demand in monopolistic competition. Applications include a new “CREMR” demand function (Constant Revenue Elasticity of Marginal Revenue): it is necessary and sufficient for...

We develop a model of international trade with a monopsonistically competitive labour market in which firms employ skilled labour for headquarter tasks and unskilled workers to conduct a continuum of production tasks. Firms can enter foreign markets through exporting and through offshoring, and...
