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...

We analyse two potential effects arising from regional (and with EU) integration—increased quality of institutions (including the quality of financial institutions) and, economic policies and reduced multilateral exchange rate volatility—in a conditional convergence growth framework for MENA countries. To this purpose we outline an ad hoc methodology which implements the traditional bilateral e...

Continuous-time autoregressive moving average (CARMA) processes with a nonnegative kernel and driven by a non-decreasing Lévy process constitute a useful and very general class of stationary, non-negative continuous-time processes which have been used, in particular, for the modelling of stochastic volatility. Brockwell, Davis and Yang (2011) considered the fitting of CARMA models to closely an...

This paper attempts to compare the forecasting performance of the ARIMA model and hybrid ARMA-GARCH Models by using daily data of the Iran’s exchange rate against the U.S. Dollar (IRR/USD) for the period of 20 March 2014 to 20 June 2015. The period of 20 March 2014 to 19 April 2015 was used to build the model while remaining data were used to do out of sample forecasting and check the forecasti...

This paper examines volatility models of currency futures contracts for three developed markets and two emerging markets. For each contract, standard models of the Unbiased Expectations Hypothesis (UEH) and Cost-of-Carry hypothesis (COC) are extended to derive volatility models corresponding to each of the two standard approaches. Each volatility model is formulated as a system of individual eq...

The goal of this article is an exact Bayesian analysis of the Heston (1993) stochastic volatility model. We carefully study the affect different parameterizations of the latent volatility process and the parameters of the volatility process have on the convergence and the mixing behavior of the sampler. We apply the sampler to simulated data and to some DM/US$ exchange rate data.

We test a simple model of exchange rate regime choice with data for 65 non-OECD countries covering the period 1980-94. We find that the variance of output at home and in potential target countries as well as the correlation between home and foreign real activity are powerful and robust predictors of exchange rate regime choice. Surprisingly, a more volatile foreign economy can be an argument in...
