The Journal of Finance, EarlyView.ABSTRACT We derive bounds on the rational variation in option‐implied beliefs about market returns.

Risk, Specialization, and Covered‐Interest Parity
The Journal of Finance, EarlyView.ABSTRACT Prevailing theories of financial intermediation assume an integrated financial sector with frictionless risk‐sharing. However, we identify substantial risk‐sharing frictions linked to intermediary specialization using currency derivatives markets as a laboratory. Using confidential supervisory data covering $25 trillion in daily bank exposures,
