Modeling of Stochastic Volatility to Validate IDR Anchor Currency

Pricing Currency Options Under Stochastic Volatility

This paper investigates the relative pricing performance between constant volatility and stochastic volatility pricing models, based on a comprehensive sample of options on four currencies, including the British pound, Deutsche mark, Japanese yen and Swiss franc, traded frequently in the Philadelphia Stock Exchange (PHLX) from 1994 to 2001. The results show that the model of Heston (1993) outpe...

A Survey of Currency Anchor Selection in East-West Asia

 As the number of independent countries increases and their economies become more integrated, we would expect to observe more multi-country currency :::union:::s. This paper explores the pros and cons for different countries to adopt as an anchor the US Dollar, the Euro or the Yen. In addition, it addresses the question of how co-movement of outputs and prices would respond to the formation of ...

A Brief Introduction to Stochastic Volatility Modeling

Asset modeling, stochastic volatility and stochastic correlation

Asset prices are typically modeled with the geometric Brownian motion (GBM). Correlation between the assets is exogenously modeled and then ad-hoc assigned to the asset prices. This is conceptually and mathematically unsatisfying. We create a new, simple approach, which simultaneously models stochastic volatility and stochastic correlation. This approach replicates the realworld volatility – co...

Bayesian semiparametric stochastic volatility modeling

This paper extends the existing fully parametric Bayesian literature on stochastic volatility to allow for more general return distributions. Instead of specifying a particular distribution for the return innovations, nonparametric Bayesian methods are used to flexibly model the distribution’s skewness and kurtosis while volatility dynamics follow a parametric structure. Our Bayesian approach p...
