This paper discusses the joint unpredictability of asset returns on two markets. It provides a necessary condition for joint unpredictability in term of distance between information sets. We conclude that the joint unpredictability requires a condition very strong and so, in this sense, it represents a ‘‘singularity’’. The result should give a theoretical support to the empirical evidence in favor of the predictability of the returns.

Abstract
This paper discusses the joint unpredictability of asset returns on two markets. It provides a necessary condition for joint unpredictability in term of distance between information sets. We conclude that the joint unpredictability requires a condition very strong and so, in this sense, it represents a ‘‘singularity’’. The result should give a theoretical support to the empirical evidence in favor of the predictability of the returns.File in questo prodotto:
