Based on panel data of 273 cities in China from 2010 to 2018, we apply the multiple periods difference-in-differences method in a quasi-natural experiment setting. The results show that carbon ETS can significantly reduce the level of urban-rural income inequality by 8.11% in China. More ...
For the 2D simulations, the effect of the difference between or ratio of T1,1 and T1,2 on the precision of parameter estimation was of greatest interest. In contrast to the ILT, the inverse Fourier transform (FT) is analytically well-posed and, in the discrete form, well-conditioned9. ...
Unlike the other datasets that we used, which consist of sessions on the order of tens of minutes, this dataset was recorded continuously over a period of days so that even rare identity switching would make proofreading laborious as errors would be difficult to identify and correct, in ...
One consequence of this assumption is that the injection process begins from the first day of the production period. Another consequence is that the injection rate can be very high in order to balance the production rate. To achieve a very high injection rate, a very high injection pressure ...
Model and method Model configuration Figure1A shows the model configuration of this study. We prepare a finite model domain for an infinite planar faultΣ∞in a 3D infinite elastic medium and assume that the rest of the fault plane is dragged at a constant tectonic speedVpl(i.e., the impose...
In the course studied here, students were organized into classes of 30 students, one teacher, and two teaching assistants. Differences in the composition of the student group and teaching staff between classes concerning may cause class variations in student outcomes. Even though the teacher’s role...
futures and options obtained from the TOP method. Figure5a presents the lead–lag positions between HSI and its related futures, and we find that the return of HSI futures leads that of HSI for about 20 min on most trading days during the period under study, and lags on a relatively small...
The incremental cost-effectiveness plane presents the impact of FFR-guided compared with angiography-guided PCI on the difference in quality-adjusted life-years (QALYs; until 4 years after PCI) and accompanying medical costs within this 4-year time period. Each of the 25 000 dots represents ...
These limits indicated the number of pounds that each vessel could harvest of each species (or in some cases each group of species) in each 2 month period of the year. Since the limits were set in order to avoid irreparable damage to depleted populations, and since species are harvested ...
For example, the difference in annual net CO2 flux between 2004 and 2005 was caused by the difference in GEP while Reco remained the same. Between 2008 and 2009, we observed a similar situation; however, GEP and Reco were much higher than in 2004–2005. On the other hand, differences in...
