By analyzing several profitability measures of these 1PO companies from the third year prior to listing up to the fifth year post-listing, it is found that IPO companies' operating performances as a whole peak in the year of listing or the year preceding the listing, but exhibit a fall in post-issue profitability with the decline being most pronounced in the first financial year following the year in which the listing take place. Over 30% of these IPOs suffer a loss three years after the offerings. Deterioration of post-issue performance is found to be more severe for smaller finns, highly-geared companies, fast-growing enterprises, companies with lower ownership retention by original shareholders, and companies which have managed earnings upwards at the time of listing. These observations are consistent with the higher agency costs when firms go public and that managers have timed the issue at the peak of the companies' long-run performance. Further investigation confirms that IPO companies in general make use of income-increasing accruals to manage their earnings upwards in the year when they go public. The reversal of the accruals in post-issue years further exaggerates the decline in their profitability.展开更多

Under the condition of incomplete information, each firm’s earnings man-agement will be influenced by the earnings disclosure policies of other firms. It can lead to "herd behavior" of earningsmanagement. This paper studies the relationship between earnings manipulation and rights issue policy based on thedistribution of earnings after management. The results indicate that Chinese listed companies trend towards controllingROE in the narrow ranges just above 6% and 10% .Therefore, "herd behavior" exists in the earnings management.展开更多

To this end, a novel optimal offering model is proposed for stand-alone price-taking storage participants, which accounts for recent FR market design developments in the UK, namely the trade of FR products in time blocks, and the mutual exclusivity among the multiple FR products. The model consists of a day-ahead stage, devising optimal offers under uncertainty, and a real-time stage, representing the storage operation after uncertainty is materialized. Furthermore, a concrete methodological framework is developed for comparing different approaches around the anticipation of uncertain FR utilization factors(deterministic one based on expected values, deterministic one based on worst-case values, stochastic one, and robust one), by providing four alternative formulations for the real-time stage of the proposed offering model, and carrying out an out-of-sample validation of the four model instances. Finally, case studies employing real data from UK energy and FR markets compare these four instances against achieved profits, FR delivery violations, and computational scalability.展开更多

The results indicate that the GEB has been successful and is providing a viable channel for new small and medium-sized firms to raise external capital. Four variables, the volatility variable, the turnover ratio, the winning lottery ratio and the price-earnings ratio, are important factors driving the initial- day returns in the regression analysis. The implementation of the new trading-halts policy on the GEB is found to be effective in mitigating excessive speculation. Our analysis results could be used by policy-makers to gauge the effects of policy changes on the underpricing of the initial public offerings of the GEB.展开更多

The results show that venture capitalists choose to invest in companies with higher value potential, and, in turn, the value of the companies increases after the 1PO is undertaken;foreign VC adds more value to companies than domestic venture capital. However, the profitability of VC-backed and non VC-backed companies after IPO does not differ significantly. Nevertheless, it is shown that VC plays an active role in China.展开更多

A sample from Chinese listed firms is adopted and contributes to better understand this effect in emerging markets. The spread and illiquidity significantly increases around lockup expiration in China. Furthermore, the liquidity reaction to firms' disclosure quality is explicitly related. The results confirm that higher disclosure quality is significantly associated with lower abnormal spread and illiquidity impact. The effect of lockup expiration shares on liquidity proxies differs in firm disclosure quality. Identifying the factors affecting liquidity around such events may help regulators develop policies to provide investors with greater confidence in their investments.展开更多

文摘This paper uses all 1404 initial public offerings (1PO) undertaken between 2002 and 2012 in China to analyze whether venture capital (VC) investment, especially foreign VC investment, brings more or less value-added services to the invested companies during the 3 years following the IPO. The results show that venture capitalists choose to invest in companies with higher value potential, and, in turn, the value of the companies increases after the 1PO is undertaken;foreign VC adds more value to companies than domestic venture capital. However, the profitability of VC-backed and non VC-backed companies after IPO does not differ significantly. Nevertheless, it is shown that VC plays an active role in China.

文摘Previous empirical evidence on the liquidity effect to the lockup expiration is mixed. A sample from Chinese listed firms is adopted and contributes to better understand this effect in emerging markets. The spread and illiquidity significantly increases around lockup expiration in China. Furthermore, the liquidity reaction to firms' disclosure quality is explicitly related. The results confirm that higher disclosure quality is significantly associated with lower abnormal spread and illiquidity impact. The effect of lockup expiration shares on liquidity proxies differs in firm disclosure quality. Identifying the factors affecting liquidity around such events may help regulators develop policies to provide investors with greater confidence in their investments.
