Zero-sum game
The Chartered Institute of Procurement & Supply (CIPS) Glossary of procurement terms, defines a A zero-sum game as: ‘…an interaction where every gain by one person is an equal loss to the other, so the net gain (the total of the benefits to both parties) is zero.’
The glossary of statistical terms, published by the Organisation for Economic Co-operation and Development (OECD), defines a zero sum game as: ‘A game played by a number of persons in which the winner takes all the stakes provided by the losers so that the algebraic sum of gains at any stage is zero. It has been argued that many decision problems may be viewed as zero sum games between two persons.’
