My current research covers a number of distinct areas of both applied and theoretical econometrics: a partially-heterogeneous panel data approach to asset (factor) pricing models; the forecast evaluation of inflation, output growth, exchange rates and stock prices using the multivariate cointegrating VAR models and the semi-parametric functional autoregression; the nonlinear ARDL-based error correction modeling in time series and dynamic panels; the dynamic quantile regression modeling of cointegration; the nonlinear panel data modeling with local averaging and cross-section dependences; the regime-switching two-period generalized ECM with an application to the limits to arbitrage. Most of these works being carried out and to be completed in near future would hopefully provide useful techniques, and thus will be of widespread applicability in Economics and Finance. I hope that these researches would help to uncover various important and complicated issues surrounding the equilibrium theories of empirical finance, macroeconomics and international trade.
