As increasing attention has been given in recent literature to the potential of the Chinese financial market, we investigate the strength of shared dynamics among East Asian stock markets, by examining both the long-term and short-term comovements. In doing so, the cointegration analysis is used to assess the long-term relationship, whereas the notions of cofeature as well as contemporaneous correlation are employed to discuss the short-term relationship. The basic finding is that evidence for short-term comovement between the Korean and Chinese stock markets appears to be strong, while evidence for long-term relationship is rather weak. Empirical results from subsamples suggest that both the long-term and short-term relationships have strengthened since the acquisition of QFII qualification by Korean financial firms. These observations indicate that the international linkage between the two countries has strengthened along with increasing opportunities for international investment in the Chinese stock market.

Short-term effects of air pollution on the health of residents in the Metropolitan Area of Monterrey, Mexico were assessed from 2012–2015 using a time-series approach. Guadalupe had the highest mean concentrations for SO2, CO and O3; whereas Santa Catarina showed the highest NO2 concentrations. Escobedo and Garcia registered the highest levels for PM10. Only PM10 and O3 exceeded the maximum permissible values established in the Mexican official standards. Most of pollutants and municipalities showed a great number of associations between an increase of 10% in their current concentrations and mortality, especially for people >60 years. Different scenarios resulting from climatic change were built (increases of 5–25% in daily mean temperature), but only the increase of 25% (5 °C) showed a significant association with air pollutant concentrations and mortality. All pollutants and municipalities showed significant increases in relative risk indexes (RRI) resulting from an increase of 5 °C when people >60 years was considered. Results were comparable to those reported by other authors around the world. The RRI were low but significant, and thus are of public concern. This study demonstrated that the elderly is strongly threatened not only by atmospheric pollution but also by climatic change scenarios in warm and semiarid places.


Subject South-east Asian tax bases. Significance Indonesia's tax amnesty programme enters its third phase in 2017. The amnesty will generate short-term revenue, but it is not a solution to a wider problem of limited tax bases found across the ASEAN core economies of Indonesia, Malaysia, the Philippines, Singapore and Thailand. Impacts Bilateral tax treaties may change following OECD reforms, even if South-east Asian states are not party to the initiatives. Compliance costs for country-by-country reporting for multinational companies under the OECD initiatives could be substantial. More efficient tax collection and wider tax bases could benefit ASEAN states' development such as infrastructure.


Subject India's new policy on FDI and its impact on Chinese investment. Significance India last month introduced stricter rules for investment from bordering countries, saying it wanted to prevent “opportunistic” takeovers and acquisitions at a time when the COVID-19 pandemic is bringing down the share value of major Indian companies. The move, notified under the Foreign Exchange Management Act, was almost certainly made with China in mind. China is one of India’s fastest-growing sources of foreign direct investment (FDI). Impacts Chinese manufacturers will favour investment in certain South-east Asian countries rather than India in the short term. India may fast-track Chinese investment in infrastructure while putting those in fintech under greater scrutiny. Once the pandemic crisis dissipates, India will roll out ambitious plans to attract foreign factories relocating from China.

While dual antiplatelet therapy (DAPT) is essential after percutaneous coronary intervention (PCI), the optimal duration is affected by various factors. However, the effect of ethnicity on DAPT duration has not been fully evaluated. In this study, we evaluated the different effect of DAPT duration by ethnicity. We searched Pubmed, Embase, Cochrane library, and relevant websites to search for randomized clinical trials (RCT) assessing the clinical impact of long term DAPT (L-DAPT) and short term DAPT (S-DAPT). Studies were divided by ethnicity, and we compared the efficacy and safety of DAPT duration in each ethnic group. Thirteen RCTs including 38,255 patients (five East Asian studies and eight non–East Asian studies) were eligible for analysis. For the primary outcome, L-DAPT showed a significantly lower rate of primary outcome only in non–East Asians (S-DAPT vs. L-DAPT, odds ratio (OR) = 1.16, 95% confidence interval (CI): 1.02–1.32, p = 0.02), while in East Asians, the effect of S-DAPT and L-DAPT were comparable. S-DAPT significantly increased ischemic events only in non–East Asians (S-DAPT vs. L-DAPT, OR = 1.24, 95% CI: 1.09–1.42, p <0.01), while bleeding events were decreased by S-DAPT in both ethnicities. These results demonstrate that the adequate DAPT duration after PCI may be different in East Asians.
