Continuous time modified Cox-Ingersoll-Ross (1985) stochastic model is employed, combining with Hamilton (1989) type Markov regime switching framework, to study daily foreign exchange rates, where all parameter values depend on the value of a continuous time Markov chain. The Expectation-Maximization algorithm is extended, generalized, applied to a more general class of regime switching models ...

We investigate the Indian exchange rate regime starting from 1993 when trading in the Indian rupee began up to the end of 2007. This reproduces the analysis from Zeileis, Shah, and Patnaik (2010) which includes a more detailed discussion. 1 Analysis Exchange rate regime analysis is based on a linear regression model for cross-currency returns. A large data set derived from exchange rates availa...

The breakdown of the Bretton Woods system and the adoption of generalized ‡oating exchange rates ushered in a new era of exchange rate volatility and uncertainty. This increased volatility lead economists to search for economic models able to describe observed exchange rate behavior. In the present paper we propose more general STAR transition functions which encompass both threshold nonlineari...

This paper explores the classic question regarding the costs and bene ̄ts of limiting exchange rate volatility starting from the premise that asset markets play an important role in aggregating information. I ̄nd that government trading, despite being completely observed, alters the ability of an asset market to reveal information. The main insight of the paper is that managing the exchange rate...
