Identification through heteroskedasticity in heteroskedastic simultaneous equations models (HSEMs) is considered. The possibility that heteroskedasticity identifies the structural parameters only partially is explicitly allowed for. The asymptotic properties of the identified parameters are derived. Moreover, tests for identification through heteroscedasticity are developed and their asymptotic distributions are derived. Monte Carlo simulations are used to explore the small sample properties of the asymptotically valid methods. Finally, the approach is applied to investigate the relation between the extent of economic openness and inflation.

He works in the area of econometric methods/theory, time series analysis, and financial econometrics. Some of his research has been published in good journals such as JASA, JBES, Journal of Econometrics, and Econometric Theory. In addition to his recent research about identification and inference of simultaneous equations models, he is also investigating the price discovery issues, and the risk return relationship in empirical finance.
