An approximation pricing algorithm in an incomplete market: A differential geometric approach
Gao, Yuan; Lim, Kian; Ng, Kah - In: Finance and Stochastics 8 (2004) 4, pp. 501-523
The minimal distance equivalent martingale measure (EMM) defined in Goll and Rüschendorf (2001) is the arbitrage-free equilibrium pricing measure. This paper provides an algorithm to approximate its density and the fair price of any contingent claim in an incomplete market. We first approximate...
