RT Generic T1 Explaining export regional involvement through marketing strategy : the case of Spanish companies exporting to Latin America A1 Lado, Nora A1 Martínez-Ros, Ester A1 Valenzuela, Ana AB The equivalence between the absence of arbitrage and the existence of an equivalent martingale measure fails when an infinite number of trading dates is considered.
