Since mid 2007 there has been a dramatic rise in prices for basic foods such as internationally traded varieties of rice, corn and wheat. At the moment, it is rather impossible to estimate how far speculation in the commodity markets has contributed to this development. Irrespective of this, a...

This paper examines how delivery tariffs and private quality standards are determined in vertical relations that are subject to asymmetric information. We consider an infinitely repeated game where an upstream firm sells a product to a downstream firm. In each period, the firms negotiate a...

We analyze how consumer preferences for one-stop shopping affect the bargaining relationship between a retailer and its suppliers. One-stop shopping preferences create demand complementarities among otherwise independent products which lead to two opposing effects on upstream merger incentives:...

This paper highlights the strategic role retailers private quality standards play in food supply chains. Considering two symmetric downstream firms that are exclusively supplied by a finite number of upstream firms and letting the upstream firms decide which retailer to supply, we show that...
