Policy design in oligopolistic settings depends critically on the mode of competition between firms. We develop a model of oligopoly intermediation that reveals the mode of competition to be an equilibrium outcome that depends on the relative degree of rivalry between firms in the upstream and...

We develop a model of competition between retailer chains with a structural estimation of the demand and supply in the supermarket industry in France. In the model, supermarkets compete in price and brand offer over all food products to attract consumers, in particular through the share of...

We show that collective bargaining can enhance retailers’ buying power vis-àvis their suppliers. We consider a model of vertically related markets, in which an upstream leader faces a competitive fringe of less efficient suppliers and negotiates secretly with several firms that compete in a...

This paper empirically analyzes how the adoption of Information Technologies (IT) has changed the organization of global supply chains. We focus on international mergers, which are a growing and important component of foreign direct investment. We use data on North-South vertical mergers and...

Innovative start-ups and venture capitalists are highly clustered: Silicon Valley is probably the best-known example. Clusters differ in the contracts they use, and in how they perform. I explore the link between spillovers, contractual design and performance. I find that more "incomplete"...

Contractual execution generates hard information, available to the contracting parties, even when contracts are secretly executed. Building on this simple observation, the paper shows that incomplete contracts can be preferred to complete contracts. This is because (i) execution of incomplete...

This paper explores a new role for venture capitalists, as knowledge intermediaries. A venture capital investor can communicate valuable knowledge to an entrepreneur, facilitating innovation. The venture capitalist can also communicate the entrepreneur's innovative knowledge to other portfolio...

Considering a vertical structure with perfectly competitive upstream firms that deliver a homogenous good to a differentiated retail duopoly, we show that upstream fixed costs may help to monopolize the downstream market. We find that downstream prices increase in upstream firms'fixed costs when...

In a two-stage game with three firms and two countries, we study the profitability of a domestic merger in the context of an international oligopoly game with differentiated products and in a strategic trade policy environment. In contrast to a completely unregulated economy, we show that the...

We develop a model of interlocking bilateral relationships between upstream manufacturers that produce differentiated goods and downstream retailers that compete imperfectly for consumers. Contract offers and acceptance decisions are private information to the contracting parties. We show that...
