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...

We analyze inflation persistence in several industrial and emerging countries in the recent past by estimating reduced-form models of inflation dynamics. We select a very representative group of 23 industrial and 17 emerging economies. Our sample period is comprised of quarterly data and starts...

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.

This paper employs a recently developed parametric technique to obtain density forecasts for the Brazilian exchange rate, using the exchange rate options market. Empirical results suggest that the option market contains useful information about future exchange rate density. These results...

A short review of the literature discusses different approaches on strategy, their agreeded and disagreeded points, and also discusses the foundations that are used to separate multiple perspectives on the subject according to several scholars. The paradigm distinction proposed by Burrell &...

This paper presents a small-scale structural model to the Brazilian economy with an external block. The nominal exchange rate forecast is based on an uncovered interest rate, which is estimated in monthly terms since the switching of the exchange regime in 1999. As a risk premium measurement,...

In this paper, we analyze the importance of curvature term structure movements on forecasts of interest rate means. An extension of the exponential three-factor Diebold and Li (2006) model is proposed, where a fourth factor captures a second type of curvature. The new factor increases model...

This article analyzes empirically the herding behavior on emerging markets, measuring the degree of herding by foreign investors on emerging equity markets, and evaluating the effects of this behavior on the riskiness of the markets. We use an adaptation of the LSV Herding measure and calculate...
