Cash Holdings and M &A Performance: Evidence from China’s GEM Market
No full textAs a form of enterprise’s external expansion, merges and acquisitions (M &A) activities have been the focus of research in recent years. This paper selected growth enterprise market (GEM) companies from 2011 to 2017 includes 809 observations as the sample to explore the impact of cash holdings on merger and acquisition performance. It was found that cash holding has no significant effect on the short-term merges and acquisitions (M &A) performance, and has a significant positive correlation effect on the long-term merges and acquisitions (M &A) performance. Further research found that when internal control is a moderator, it can strengthen the positive correlation effect of cash holding on the long-term performance of M &A. Under the condition of cash payment or over-funding or no financial advisor, there is no significant positive correlation between long-term performance and cash holding
Difference based Ridge and Liu type Estimators in Semiparametric Regression Models
Full text linkWe consider a difference based ridge regression estimator and a Liu type estimator of the regression parameters in the partial linear semiparametric regression model, y = Xβ + f + ε. Both estimators are analysed and compared in the sense of mean-squared error. We consider the case of independent errors with equal variance and give conditions under which the proposed estimators are superior to the unbiased difference based estimation technique. We extend the results to account for heteroscedasticity and autocovariance in the error terms. Finally, we illustrate the performance of these estimators with an application to the determinants of electricity consumption in Germany.Difference based estimator; Differencing estimator, Differencing matrix, Liu estimator, Liu type estimator, Multicollinearity, Ridge regression estimator, Semiparametric model

Urediniospores of <i>H. minispora</i> have 4–6 scattered germ pores, but <i>H. hakodatensis</i> possesses only 2–4 germ pores at the equatorial region (Ji <i>et al.</i> 2018). <i>H. minispora</i> shares the host <i>Blechnopsis</i> with <i>H. aculeata</i> and <i>H. polypodii</i> (Ono 2017).
