Cassese, Gianluca 2005 In this paper we propose a model of asset prices consistent with the no-arbitrage principle but allowing for the existence of "bubbles". The structure of bubbles is explicitly characterized and we show that, for example, they may be of either sign. Furthermore, we discuss the existence of bubbles under alternative definitions of absence of arbitrage opportunities. application/pdf https://susi.usi.ch/global/documents/318174 https://n2t.net/ark:/12658/srd1318174 https://susi.usi.ch/documents/318174/files/cassese_IJTAF_2005.pdf eng info:eu-repo/semantics/altIdentifier/doi/10.1142/S0219024905003074 info:eu-repo/semantics/altIdentifier/ark/12658/srd1318174 info:eu-repo/semantics/openAccess License undefined International journal of theoretical and applied finance. - World scientific. - 2005, vol. 8, no. 4, p. 523-536 Bubbles arbitrage finitely additive measures fundamental theorem of asset pricing martingales info:eu-repo/classification/udc/33 A note on asset bubbles in continuous-time http://purl.org/coar/resource_type/c_6501
