Section: ArticlesTitle: A Benchmark approach to risk-minimization under partial information / Claudia Ceci, Katia Colaneri, Alessandra CretarolaqAuthor: Ceci, ClaudiaNotes: Sumario: The goal of this paper is to investigate (locally) risk-minimizing hedging strategies under the benchmark approach in a financial semimartingale market model where there are restrictions on the available information. More precisely, we characterize the optimal strategy as the integrand appearing in the GaltchoukKunitaWatanabe decomposition of the benchmarked contingent claim under partial information and provide its description in terms of the integrand in the classical GaltchoukKunitaWatanabe decomposition under full information via dual predictable projections. Finally we show how these results can be applied to unit-linked life insurance contracts.Related records: En: Insurance : mathematics and economics. - Oxford : Elsevier, 1990- = ISSN 0167-6687. - 03/03/2014 Volumen 55 Número 1 - marzo 2014 Other categories: 6Rights: In Copyright (InC)Referencias externas:
