Abstract
In an incomplete financial market where asset prices are continuous semimartingales, we establish the convergence of the p-optimal martingale measures to the minimal entropy martingale measure as p tends to 1. The result is achieved exploiting the theory of BMO-martingales and semimartingale backward equations.
