To share or not to share? – that is the question for competition authorities

Competition authorities in the USA and Europe tend to have a different approach to firms that have a dominant market position by virtue of their ownership of specific intellectual property, such as software codes. Thus companies such as Microsoft can exploit network economies, thereby making it hard for rival firms to compete. After all, if most people use Windows, there is an incentive to keep using it so as to be compatible with other users. Similar arguments apply to the ownership of physical property, such as ports, airports, railways and power lines, where the owners may choose to deny access to competitors.

So should companies such as Microsoft grant rivals access to their intellectual property? Would such access increase competition, or would it be a disincentive for rivals to innovate? The following article from The Economist considers the issue and refers to a recent paper by Sir John Vickers, former head of the Office of Fair Trading and now Warden of All Souls College, Oxford and President of the Royal Economic Society. He argues for a mid-way course between Europe and America – more interventionist than in the USA, but less rigidly regulated than in the EU.
