Industry structural inefficiency and potential gains from mergers and break-ups: A comprehensive approach

Peyrache, Antonio - In: European Journal of Operational Research 230 (2013) 2, pp. 422-430

An efficiency indicator of industry configuration (allowing for entry/exit of firms) is presented which accounts for four sources components: (1) size inefficiencies arising from firms which can be conveniently split into smaller units; (2) efficiency gains realized through merger of firms; (3)...
