Constructed from high-frequency data, realized volatility (RV) provides an accurate estimate of the unobserved volatility of financial markets. This paper uses a Bayesian approach to investigate the evidence for structural breaks in reduced form time-series models of RV. We focus on the popular...

How to measure and model volatility is an important issue in finance. Recent research uses high-frequency intraday data to construct ex post measures of daily volatility. This paper uses a Bayesian model-averaging approach to forecast realized volatility. Candidate models include autoregressive...

We propose a new joint model of intraday returns and durations to study the dynamics of several Chinese stocks. We include three U.S. stocks for comparison. Flexible innovation distributions are used for durations and returns, and the total variance of returns is decomposed into different...

This study intends to focus on the physicians, and to examine the input-output relationships between the medical resources used by these physicians and the quantity of medical services provided by them, in order to analyze the productivity and efficiency of physicians. In addition, by applying...

China's economy has maintained a rapid growth rate over the past two decades; however, its stock market has exhibited a very different level of performance during financial crises. In this paper, we try to explain this phenomenon and answer two important questions: Is there financial contagion...

Informatization, a policy of integrated telecommunications development, is regarded as one of the driving forces behind the Chinese government's new socialist countryside program. Various national and provincial programs have been initiated to connect the agricultural communities to the...

A trade-off exists between the Gelfand and Dey (1994) and Chib (1995) methods to calculate the marginal likelihood in Bayesian estimation. Using the Markov Chain Monte Carlo method, we demonstrate that the performance of the two methods is fairly close.

Landslides are occurring more frequently in China under the conditions of extreme rainfall and changing climate, according to News reports. Landslide hazard assessment remains an international focus on disaster prevention and mitigation, and it is an important step for compiling and...

This paper examines the contrast between China's and India's universal service policies as manifestations of the two states' differing self-conceptualizations and legitimation strategies. We examine the timeline of universal service policies in the two countries, differentiating between the...

This paper is a comparative analysis of the telecommunications policy-making process in China and India. Adopting an institutionalist perspective and multi-streams framework, the paper analyzes the formal structures, rule-making procedures and interest groups involved in telecommunications...
