This study presents an environmental, social, and governance (ESG) strategic model to manage pharmaceutical supply chains with financial obstacles. ESG environmental, social, and governance research can help managers make informed decisions so that managers can better choose the corresponding...

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...

The implementation of Dual-Credit Policy on April 1, 2018 is a new attempt to promote the development of the new energy vehicle market in China. Since the implementation of the policy, on the one hand, the new energy automobile industry has developed rapidly, on the other hand, many automobile...

The empirical literature examines the effect of exchange rate on energy demand. However, the existing literature fails to investigate the effect during different states of energy demand, that is, when energy demand is relatively high and when it is quite low. We extend the prior literature by...

We construct a sovereign default network by employing high-dimensional vector autoregressions obtained by analyzing connectedness in sovereign credit default swap markets. We develop four measures of centrality, namely, degree, betweenness, closeness, and eigenvector centralities, to detect...

Logistics is an essential service for manufacturing because it supports the coordination and integration of global production activities, ultimately reducing costs and improving efficiency. However, it is not clear that the complex structural relationship between logistics and manufacturing...

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....

Information and communication technologies (ICTs) are increasingly seen as integral to the development process. This paper reviews some of the evidence for the link between telecommunications and the Internet and economic growth, the likely impact of the new ICTs on income inequality and...

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...

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...
