This paper studies whether trading costs or transparency/tradability are more important to price discovery using a unique dataset of currency options that trade simultaneously in two parallel markets. The Over-The-Counter (OTC) market is characterized by sophisticated investors, low trading...

We derive the equilibrium asset expected returns when there is ambiguity in asset expected returns, as well as ambiguity in asset return variances. In our model, ambiguity risk is systematic in nature and is non-diversifiable. Under regularity conditions, expected asset returns are linearly...
