We establish necessary and sufficient conditions for the individual optimality of a consumption-portfolio plan in an infinite horizon economy where agents are uniformly impatient and fiat money is the only asset available for inter-temporal transfers of wealth. Next, we show that fiat money has...

It is well known that, under uniform impatience, positive net supply assets are free of bubbles for non-arbitrage kernel deflators that yield finite present values of wealth. However, this does not mean that prices cannot be above the series of deflated dividends for the deflators given by the...

When infinite-lived agents trade long-lived assets secured by durable goods, equilibrium exists without any additional debt constraints or uniform impatience conditions on agents’ characteristics. Also, price bubbles are absent when physical endowments are uniformly bounded away from zero.

We use bank-level data to model the demand for bank services in Brazil following the discrete choice literature. A multinomial logit specification is used to study the demand for time deposits, for an aggregate of demand and passbook savings deposits, and for loans. Market for each of these...

Fixed income options contain substantial information on the price of interest rate volatility risk. In this paper, we ask if those options will provide information related to other moments of the objective distribution of interest rates. Based on a dynamic term structure model, we find that...

This paper investigates an intertemporal optimization model to analyze the current account through Campbell & Shiller’s (1987) approach. In this setup, a Wald test is conducted to analyze a set of restrictions imposed to a VAR, used to forecast the current account for a set of countries. We...
