Before revision: Using the elements from the theory of quadratic backward stochastic differential equations with unbounded terminal data , we solve an exponential utility maximization problem with unbounded random endowments under portfolio constraints. Our results thus generalize the previous results of Hu et al. (2005) [Ann.
