We present a North-South model of international trade in which differentiated products are developed in the North. Sectors are populated by final-good producers who differ in productivity levels. Based on productivity and sectoral characteristics, firms decide whether to integrate into the...

Depending on the definition of the tax base, the statutory corporate tax rate implies rather different measures of effective average and marginal tax rates. This paper develops a model of a monopolistically competitive industry with extensive and intensive business investment and shows how these...

This paper develops an industry equilibrium model of vertical integration under contractual imperfections with specific input suppliers and external investors. I assume that vertical integration economizes on the needs for contracts with specific input suppliers at the cost of higher financial...

This paper examines how firms interact with their rivals. The main novelty of our approach is that we let conjectural variations depend on the actual ability of other firms to react, which we measure by both the physical capacity and financial status of firms. Our main findings are threefold....

Understanding the development of chainstores is important given the large GDP share of services and the continuing importance of chains in bringing these services to market. Service chains provide a puzzle because they take a long time to develop even when there are obvious expansion...

I survey the influence of Grossman and Hart's (1986) seminal paper in the field of International Trade. I discuss the implementation of the theory in open-economy environments and its implications for the international organization of production and the structure of international trade flows. I...

We investigate the roles of productivity and the specificity of inputs for the international sourcing strategy of firms which are part of a multinational network. We present a framework in which firms decide to import from a foreign independent supplier or from their related party abroad...

This paper reviews the recent theoretical literature on heterogeneous firms and trade, which emphasizes firm selection into international markets and reallocations of resources across firms. We discuss the empirical challenges that motivated this research and its relationship to traditional...

This paper analyses the impact of inequality on growth when technical progress is driven by innovations. It is assumed that consumers have hierarchic preferences. As a result inequality affects demand and therefore the incentive to innovate. Whether more inequality is harmful or beneficial for...

We develop a model in which heterogeneous firms in an industry choose their modes of organization and the location of their subsidiaries or suppliers. We assume that the principals of a firm are constrained in the nature of the contracts they can write with suppliers or employees. Our main...
