Pricing payment cards
American Economic Journal: Microeconomics 5(3): 206–231
Emilio Calvano

Payment card networks, such as Visa, require merchants' banks to pay substantial "interchange" fees to cardholders' banks, on a per transaction basis. This paper shows that a network's
profi t-maximizing fee induces an inefficient price structure, over-subsidizing card usage and over-taxing merchants.

Vertical effects when assessing passive minority shareholdings
E.CA Compact
minority shareholdings, vertical effects

While the discussion among economists on passive minority shareholdings focusses on horizontal unilateral as well as coordinated effects of such acquisitions, in some cases the main concerns of market participants are of a vertical nature. When analysing such vertical effects one needs to account for the fact that the acquirer does not gain control over the strategic decisions of the target precluding certain foreclosure strategies. This allows a more focussed review of competitive effects.
