This paper examines the adaptive market hypothesis of Lo (2004, 2005) using the Ito and Noda’s (2012) non-Bayesian time-varying AR model in Japan. As shown
in Ito and Noda (2012), their degree of mar...

In this paper, we model dependence between operational risks by allowing risk profiles to evolve stochastically in time and to be dependent. This allows for a flexible correlation structure where the ...
Net Inflows and Time-Varying Alphas: The Case of Hedge Funds
