KadaneWe explore two connections between the concepts of coherence, as defined by de Finetti, and arbitrage-free asset pricing in financial markets. We contrast these concepts when random quantities may be unbounded. And we discuss some of the consequences for arbitrage theory when coherent previsions are merely finitely (but not countably) additive.
