In this paper we show that the approximation error of the optimal policy function in the stochastic dynamic programing problem using the policies defined by the Bellman contraction method is lower than a constant (which depends on the modulus of strong concavity of the one-period return...

Due to the unobservability of the new credit production, most of the empirical loan market studies use, instead, the observable credit stock. This substitution has been pointed out to be likely to generate biases (e.g. see Lown and Peristiani (1996)). In this paper, we show that under quite...
