This paper proposes a semiparametric realized stochastic volatility model by integrating the parametric stochastic volatility model utilizing realized volatility information and the Bayesian nonparametric framework. The flexible framework offered by Bayesian nonparametric mixtures not only...

This paper suggests a new approach to evaluate realized covariance (RCOV) estimators via their predictive power on return density. By jointly modeling returns and RCOV measures under a Bayesian framework, the predictive density of returns and ex-post covariance measures are bridged. The forecast...

In this paper, we develop a number of new composite models for modelling individual claims in general insurance. All our models contain a Weibull distribution for the smallest claims, a lognormal distribution for the medium-sized claims, and a long-tailed distribution for the largest claims....

Forecasting survival probabilities and life expectancies is an important exercise for actuaries, demographers, and social planners. In this paper, we examine extensively a number of link functions on survival probabilities and model the evolution of period survival curves of lives aged 60 over...

Based on the matching data in the China Customs, Chinese industrial enterprises, and patent databases, this study uses the propensity score matching method (PSM) and the double difference model (DID) to study the impact of Internet use on enterprise innovation. The results show that Internet use...

The double externalities of green technological innovation and disadvantages of the traditional extensive development of manufacturing industries hinder the transformation of green technological innovation in manufacturing industries. Traditional research based on behavioral logic rarely focused...

The disaster area is a constantly changing environment, which can make it challenging to distribute supplies effectively. The lack of accurate information about the required goods and potential bottlenecks in the distribution process can be detrimental. The success of a response network is...

Purpose In this paper, the authors study the effect of consumers' fairness preferences on dynamic pricing strategies adopted by platforms in a non-cooperative game. Design/methodology/approach This study applies fair game and repeated game theory. Findings This study reveals that, in a one-shot...
