In Germany exist a large number of co-operatives that are engaged in a broad variety of business activities. Their organisational structure is determined by co-operative law and to a lesser degree by statutes or by-laws. As has been shown for German rural co-operatives by applying property...

Entry deterrence can occur when downstream incumbents hold non-controlling ownership shares of a supplier which is commited to charge uniform prices to all downstream firms. The ownership shares imply a rebate on the input price for the incumbents through the profit participation. Such backward...

The established literature on partial vertical ownership has derived distinct pro- and anti-competitive effects, depending on whether the upstream or the downstream firm holds the shares (forward or backward). We show that forward ownership can have the same effects as backward ownership (and...

We review the Chicago school's single monopoly profit theory whereby an upstream monopolist cannot increase its profits through vertical integration as it has sufficient market power anyways. In our model the dominant supplier has full bargaining power and uses observable two-part tariffs. We...

We study the incentives of firms that hold partial vertical ownership to foreclose rivals. Compared to a full vertical merger, with partial ownership, a firm may obtain only part of the target's profit but may nevertheless be able to influence the target's strategy significantly. The target may...

When knowledge sharing is non-contractible, we show that competing downstream firms may prefer to help improve an inefficient alternative supply source than help to improve the technology of the efficient actual supplier—even if this is costless. A downstream firm can have incentives to...

We show that competing downstream firms may rather invest in their inefficient inhouse production than help improve the technology of the efficient supplier, even if this is costless. Even worse, a downstream firm can have strong incentives to decrease the efficiency of the supplier in order to...

This paper provides an extensive overview of the economic importance and development of the Flemish maritime ports, over the period 1995 - 2002. Focusing on the three major variables of value added, employment and investment, it also provides some information about the financial situation of a...
