Two trends have marked the politico-economic discussion in many industrialized countries in recent years. On the one hand, international production, workplace decentralization, shareholder orientation and generous manager remuneration have changed the face of firms in the primary economy. On the...

With the availability of international value added trade data it has become evident that gross export data and value added data do not provide the same information. Although gross exports crosses national borders and is the target of trade policy, value added data tell us what fragment in the...

This paper proposes a model in which the removal of barriers to trade and factor mobility is associated with endogenous fragmentation of the value-added chain. Fragmentation is the outcome of cost competition - the profit-maximizing choice of cost structure by monopolistically competitive firms....

We study the role of firm heterogeneity and imperfect competition for global production networks and the gains from trade. We develop a quantifiable trade model with two-sided firm heterogeneity, matching frictions, and oligopolistic competition upstream. More productive buyers endogenously...

This paper uses an oligopoly model with heterogeneous firms to examine how an industry adjusts to rising import competition. The model predicts that in the short run the least efficient firms in the industry become inactive, surviving firms face a fall in output, mark-ups and profits, and the...

Individual leaders have been central to the transformation of political institutions, organizations and many instances of social and economic reform. Why are some leaders able to take advantage of opportunities to successfully catalyze large-scale change while others fail? In this paper we argue...

Taxes levied on production processes (e.g. VAT), are today a very important source of government revenues in developed economies. Theories of optimal taxation conclude that these taxes are detrimental to production efficiency, when firms operate in perfectly competitive markets. These theories...

In the nineties, average firm size decreased, organisations decentralized, and workers preferences shifted from large to small firms. Our model identifies the economic forces behind this trend. Small firms with little capital at risk are subject to risk-shifting. They realize more of their...
