In competitive markets, prices offered by investors play a dual role: they must induce the firm to make truthful disclosures about its expected cash flows and they must also be efficient, i.e., equal the expected future cash flows to the buyer conditional on the disclosed information. We show...

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...

Auditing may be viewed as an arrangement for reducing inefficiencies arising from the fundamental market conflict between a seller who wants as high a price as possible and a buyer who wants to pay as low a price as possible. In more general terms, sellers prefer policies that boost the stock...

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...
