修正的倒向上確界ADF泡沫檢驗(yàn)方法——來自上證綜指的證據(jù)
發(fā)布時(shí)間:2018-09-14 18:11
【摘要】:模擬蒙特卡洛分析發(fā)現(xiàn),當(dāng)兩個(gè)泡沫間隔很短或第一個(gè)泡沫比第二個(gè)持續(xù)時(shí)間較長時(shí),BSADF檢驗(yàn)方法不能準(zhǔn)確地估計(jì)出第二個(gè)泡沫,而本文修正的BSADF檢驗(yàn)方法能有效地克服此問題。通過比較這兩種方法對(duì)上證綜指泡沫的產(chǎn)生和破滅時(shí)間的估計(jì)差異,發(fā)現(xiàn)BSADF檢驗(yàn)只能檢驗(yàn)出一個(gè)泡沫,泡沫持續(xù)期為2006年12月至2007年12月,而修正的BSADF發(fā)現(xiàn)了緊鄰的第二個(gè)短暫性泡沫,發(fā)生在金融危機(jī)期間。
[Abstract]:Simulation Monte Carlo analysis shows that when the interval between two bubbles is very short or the first foam is longer than the second one, the second bubble can not be estimated accurately by the BSADF test method, which can effectively overcome this problem. By comparing the difference between the two methods, we find that the BSADF test can only test one bubble, and the bubble duration is from December 2006 to December 2007. The modified BSADF found a second immediate temporary bubble, which occurred during the financial crisis.
