New OCA theory rightly criticizes the 1960s flavour of the old approach and believes in the endogenous emergence of an OCA if countries use the facilities of an integrated financial market for their catching-up. Whereas in theories of intertemporal optimisation single agents and national economies succeed to go from indebtedness to development, in EMU they were tempted live beyond their intertemporal budget constraint. Professional observers tended to tolerate high current account deficits and loss of competitiveness as temporary phenomena by relying on the Lawson Doctrine. Actually, some EMU countries could avoid insolvency only by monetising their balance of payment deficit.gerhttp://opus.uni-hohenheim.de/doku/lic_ubh.phpOptimal currency unionIntegrationIntertemporal balance of paymentsWalters critiqueLawson doctrine330IntegrationWährungsunionEuro <Währung>WorkingPaper372358675urn:nbn:de:bsz:100-opus-7698
