Title: Utility Maximization in Imperfected Markets
Abstract: We analyze a problem of maximization of expected terminal wealth and consumption in markets with some "imperfection", such as constraints on the permitted portfolios, labor income, or/and nonlinearity of portfolio dynamics. By using general optional decomposition under constraints in multiplicative form, we develop a dual formulation. Then, under some conditions imposed on the model setting and the utility functions, we are able to prove an existence and uniqueness of an optimal solution to primal and to the corresponding dual problem by convex duality.
