In this paper, we survey some of the recent nonparapmetric estimation methods which were developed to price derivative contracts. We focus on equity options and staart with a so-called model-free approach which involves very little financial theory. Next we discuss nonparametric and...

Simulation-based estimation methods have become more wideky used in recent years. We propose a set of tests for structural Change in model estimates via Simulated Method of Moments (see Duffie and Singleton (1993)). These tests extend the recent work of Andrews (1993) and Sowell (1996a, b) which...
