Both the composition and type of financial claims held by the venture capitalist and entrepreneur depend on the market structure. Beside, different market structures involve different...

We present a simple model where the growth of one downstream firm generates lower wholesale prices for this firm but higher wholesale prices for its competitors (the “waterbed effect”). We derive conditions for when, even though firms compete in strategic complements, this harms consumers....
