A causal vector autoregressive (CVAR) model is introduced for weakly stationary multivariate processes, combining a recursive directed graphical model for the contemporaneous components and a vector autoregressive model longitudinally. Block Cholesky decomposition with varying block sizes is...

Epidemics represent a threat to human life and economy. Meanwhile, medical and non-medical approaches to fight against them may result in additional economic shocks. In this paper, we examine the economic impact of the 2003 SARS outbreak in China and associated government policies. Although the...

We extract cyclic information in turnover and find it can explain the momentum “echo”. The reversal in recent month momentum is the key factor that cancels out the recent month momentum and excluding it makes the “echo” regress to a damped shape. Both rational and behavioral theories can...

In this study, we constitute an adaptive hedging method based on empirical mode decomposition (EMD) method to extract the adaptive hedging horizon and build a time series cross-validation method for robust hedging performance estimation. Basing on the variance reduction criterion and the...

The second near-infrared (NIR-II) photothermal therapy (PTT) is emerging as an effective therapeutic regimen for diverse diseases owing to its deep penetration and large maximum permissible exposure. However, the relatively long irradiation time (more than 5 mins) in most of NIR-II PTT remained...

In the process of geothermal well drilling, the high-temperature rock in the reservoirs is cooled by different cooling media, which leads to the change of mechanical properties, affecting the rock-breaking efficiency of the bit. Sandstone and granite were taken as the research objects and heated...

China’s key forested region is located in the northeast and consists of state forest enterprises which manage forest harvesting and reforestation. Deforestation is a major problem there and has resulted in several central government reforms. We develop a framework for assessing the social cost...

Cooperative game theory has proposed different notions of powerful players. For example, big-boss games (Muto et al., 1988) and clan games (Potters et al., 1989) are particular cases of veto games (Bahel, 2016). The present paper extends these veto games by assuming that there is a given subset...
