In this paper I give a method for finding long-run-average policies in the undiscounted economic growth problem using approximations by finite horizons. Required hypothesis is the strong interiority of T-horizon solutions

In this paper we model foreign capital flow to Brazil as stemming from an investment decision that whose risk depends on the expected rate of loss of foreign reserves. This motivates the estimation of an empirical relationship between these two variables that is valid for "normal" periods (when...

The Brazilian exchange rate has suffered strong fluctuations in the last year. They resulted from the Argentina crises and the energetic crises which influenced expectations about the future value of this variable, however the fundamentals of the economy did not vary significantly. In this paper...

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...

We build a model of credit card payments where the retailers are allowed to charge differential prices depending on the instrument of payment chosen by the consumer. We follow the Rochet and Wright (2010) approach, but assuming a credit card system without a no-surcharge rule or any type of...

Using a discrete-time version of the Ramsey Vintage Capital Model we provide a characterization of the set of initial capital stocks compatible with a predefined scrapping time, given the rate of technical progress and the level of capital productivity. Each profile of initial capital stock in...

Purpose – The purpose of this paper is to model a credit card market where the retailers may charge differential prices depending on the instrument of payment used by the consumer. According to the research agenda proposed by Rochet and Wright (2010), the authors find conditions for the...
