We analyze the joint convergence of sequences of discounted stock prices and the Radon-Nicodym derivatives of the minimal martingale measure when interest rates are stochastic. Therefrom we deduce the convergence of option values in either complete or incomplete markets. We particularize the...

In the setting of incomplete markets, this paper presents a general result of weak convergence for derivative assets prices. It is proved that the minimal martingale measure first introduced by Follmer and Schweizer is a convenient tool for the stabilization under convergence. This extends...

In this paper, address the problem of testing persistent causality between integrated, possibly cointegrated, time series.

In this paper we use a Threshold AutoRegressive (TAR) model to capture the non-linear dynamics of 7 real effective exchange rates, defines for the recent floating period. The so-called real exchange rate -real interest rate model is exploited in a novel way to define the thresholds.
