The contributions of this article are threefold. First, we show that restrictions on optimal expected growth rates lead to good-deal valuation bounds with good dynamic properties in a general model. Secondly, we describe the dynamics of the valuation bounds and of a suitable hedging strategy in a Wiener space setting by BSDE solutions where, finally, the corresponding hedging strategy is obtained as the minimiser of a suitable a-priori risk measure of good-deal type. 2 General framework and preliminaries Let (Ω, F , F, P ) be a stochastic basis with fixed time horizon T¯ < ∞ and a filtration F = (Ft )t∈[0,T¯] satisfying the usual conditions of right-continuity and completeness.
In this sense, we have worked out a concrete solution to a dynamic inf-convolution problem. 4) has been obtained for a prototypical model where the martingale component of the risky asset prices is given by independent Brownian motions. As with [3, 4], the focus of  is on the minimisation of risk measures but proofs make less use of BSDE theory. Despite these close relations, the perspective for our problem is in the following aspect opposite to that of the literature cited. For us, the starting point has been not a given a-priori risk measure from which a so-called market-consistent risk measure is to be found (see ) by optimal risk-sharing (hedging) with the market.
