We analyze optimal correlation levels in information technologies when multiple signals are available as contracting mechanisms within the principal-agent paradigm. We identify sufficient conditions ensuring that uniformly lower-correlation functions (in action levels) are preferred, as well as...

In classical perfect and complete markets prices form a Martingale and stock returns (or equivalently, successive price changes) are serially uncorrelated. However, there is evidence that stock returns are serially correlated in both the short and the long-term; this has been construed as a...

In classical perfect and complete markets, prices form a Martingale and stock returns (or equivalently, successive price changes) are serially uncorrelated. However, there is considerable evidence in the finance literature showing that stock returns are serially correlated both in the short and...
