Introduction: China is facing significant health care challenges, not only with infectious diseases but also with the burden of chronic diseases. Particularly in rural China, its residents are facing serious problems in seeking health care services due to their limited healthcare resource and...

Forecasting oil prices has been of great interests for macroeconomists in the recent years. Our article contributes to this strand of the literature by using a dynamic model averaging (DMA) method to improve forecasting accuracy of real oil prices. The advantage of DMA is that the method...

This study examines the impact of truncation, i.e., the unavailability of extremely deep-out-of-the-money option quotes, on the model-free implied moment estimators of Bakshi et al. (2003) and suggests how truncation should be controlled for implied higher moment estimation. We show that...

External imbalance is a central variable in international economics and recent research shows it is priced in currency portfolios. But Ang et al. (2017), among others, show that with a small and time-varying cross section, tests with individual assets are preferable. We find testing with...

Dynamic minimum variance hedge ratios (MVHRs) have been commonly estimated using Bivariate GARCH model that overlooks basis effect on the time-varying variance-covariance of spot and futures returns. This paper proposes an alternative specification of the BGARCH model in which the basis effect...

This paper studies the common jump dynamics in natural gas futures and spot markets within a bivariate autoregressive jump intensity-GARCH framework (BARJI-GARCH). We particularly examine the role of weather as a short-run demand factor and inventory as a short-run supply factor in explaining...

Empirical evidence suggests that unconditional variance of exchange rate return series is subject to occasional structural breaks that may induce spurious phenomenon of high persistence and long memory of volatility processes. In this paper, we investigate the effects of such breaks on estimated...

This paper examines the dynamic dependence structure between Chinese Yuan and each of ve other currencies in the Asia-Paci fic region on non-deliverable forward contracts over the period of July 4, 2006 throughout August 31, 2011. Using the date that Lehman Brothers led for bankruptcy as the...

This paper examines the changing nature of volatility spillovers among the U.S. and eight East Asian stock markets between two financial crises: the Asian currency crisis and the U.S. subprime credit crisis. Our empirical results suggest that volatility is not always spilled over from directly...

Financial uncertainty and macroeconomic uncertainty are commonly proxied separately by the volatility of stock returns or key macroeconomic variables, respectively. We propose a portfolio-based measure (PBMEU) that aims to capture aggregate uncertainty in both financial markets and the...
