آیا اصلاحات نهادی باعث بهبود تاثیر شهرت بانک سرمایه گذاری بر روی عملکرد بلندمدت سهام عرضه اولیه عمومی می شود؟

This study examines the impact of investment bank (IB) reputation on the long-term stock price performance of Chinese initial public offerings (IPOs) over the period 1993 to 2010. For comparison purposes, the whole sample period is separated into two sub-periods by the 2001 IPO allocation system reform: the quota system period from January 1st, 1993 to April 22nd, 2001 (hereafter, the pre-reform period) and the approval system period from April 23rd, 2001 to December 31st, 2010 (hereafter, the post-reform period). Using two time-varying proxies for IB reputation, we find no impact of IB reputation on the three-year buy-and-hold abnormal returns (BHARs) during the pre-reform period, but a significantly positive impact during the post-reform period. Our results are robust to various alternative methodological approaches in controlling for the problem of endogeneity and the cross-sectional correlations in abnormal returns.
