Richard Gerlach's research interests lie mainly in financial econometrics and time series. His methodological work has concerned developing computationally intensive Bayesian methods for inference, diagnosis and model comparison for time series models; with recent focus on nonlinear threshold heteroskedastic models and volatility forecasting. He also has an interest in estimating logit models incorporating misclassification. His applied work has involved assessing asymmetry in major international stock markets, in response to local and exogenous factors; co-integration analysis assessing the effect of the Asian financial crisis on long term relationships between international real estate investment markets; stock selection for financial investment using logit models; option pricing and hedging involving barriers; and factors influencing the 2004 Federal election.
His research papers have been published in Journal of the American Statistical Association, Journal of Time Series Analysis and the International Journal of Forecasting. He has been an invited speaker and regular presenter at international conferences such as the International Association for Statistical Computing world conference, the International Symposium on Forecasting and the International Statistical Institute sessions.
