Mengheng’s research is mostly computation-intensive and employs either sequential Monte Carlo method (Bayesian) or simulated maximum likelihood (frequentist), depending on the objective function of a specific research question. In Mengheng’s work, all models, methodologies, and computer programs are motivated by real-life economic and financial problems. For instance, central banks need to forecast inflation for implementing monetary policies and understand their transmission channel. Or Investors would like to balance their expected gain against hidden time-varying volatility, managing a portfolio that takes many positions. Mengheng is proud to uphold academic integrity and professionalism when conducting research.
