About
Professor Joshua Chan's current research focuses on high-dimensional Bayesian time series and state space models applied to empirical macroeconomic analysis, forecasting, and real-time measurement. His work encompasses large Bayesian vector autoregressions (VARs) with innovations such as shrinkage priors, flexible covariance structures, stochastic volatility, and time variation. He also develops high-dimensional state space models that enable efficient Bayesian estimation in the presence of missing or mixed-frequency data, emphasizing scalable computation techniques. Additionally, Professor Chan investigates trend inflation models through flexible unobserved components models and related extensions, contributing to the understanding and measurement of inflation dynamics. His research outputs include MATLAB code and datasets that support reproducibility and practical application of his methodologies. Professor Chan has coauthored books on statistical modeling and computation, as well as Bayesian econometric methods, reflecting his expertise in both theoretical and applied econometrics. His extensive publication record in leading journals demonstrates his significant contributions to the fields of Bayesian econometrics, macroeconometrics, and time series analysis.

articleOpen access1st authorConditional forecasts, i.e. projections of a set of variables of interest on the future paths of some other variables, are used routinely by empirical macroeconomists in a number of applied settings. In spite of this, the existing algorithms used to generate conditional forecasts tend to be very computationally intensive, especially when working with large Vector Autoregressions or when multiple linear equality and inequality constraints are imposed at once. We introduce a novel precision-based sampler that is fast, scales well, and yields conditional forecasts from linear equality and inequality constraints. We show in a simulation study that the proposed method produces forecasts that are identical to those from the existing algorithms but in a fraction of the time. We then illustrate the performance of our method in a large Bayesian Vector Autoregression. Within this setting, we first highlight how we can simultaneously impose a mix of linear equality and inequality constraints on the future trajectories of several key US macroeconomic indicators over a forecast horizon spanning multiple years. Next, we test the benefits of using inequality constraints in an out-of-sample exercise spanning the period between 1995Q1 and 2022Q3 and find that imposing these constraints on the future path of Real GDP leads to significant improvement in point and density forecasts of the large BVAR model.
Large Structural VARs with Multiple Sign and Ranking Restrictions
ArXiv.org · 2025-03-26 · 1 citations
preprintOpen access1st authorCorrespondingLarge VARs are increasingly used in structural analysis as a unified framework to study the impacts of multiple structural shocks simultaneously. However, the concurrent identification of multiple shocks using sign and ranking restrictions poses significant practical challenges to the point where existing algorithms cannot be used with such large VARs. To address this, we introduce a new numerically efficient algorithm that facilitates the estimation of impulse responses and related measures in large structural VARs identified with a large number of structural restrictions on impulse responses. The methodology is illustrated using a 35-variable VAR with over 100 sign and ranking restrictions to identify 8 structural shocks.

ArXiv.org · 2025-06-02
preprintOpen access1st authorCorrespondingWe extend the standard VAR to jointly model the dynamics of binary, censored and continuous variables, and develop an efficient estimation approach that scales well to high-dimensional settings. In an out-of-sample forecasting exercise, we show that the proposed VARs forecast recessions and short-term interest rates well. We demonstrate the utility of the proposed framework using a wide rage of empirical applications, including conditional forecasting and a structural analysis that examines the dynamic effects of a financial shock on recession probabilities.
