Does corporate diversification reduce value in high technology firms?

We find that firm value is reduced via industrial diversification and this reduction in value depends upon a firm’s technology intensity. We consider that asymmetric information problems are more severe in technology intensive industries and find that high tech industry firms present distinctly larger value reduction when compared to low tech industry firms. The negative valuation effect is greater for firms that have a relatively larger amount of intangible assets and greater R&D capital. We determine that our findings are robust to different estimation methods and alternative excess value measures.     

The Effect of Ultimate Ownership on the Disclosure of Environmental Information

This study empirically examines whether environmental information disclosure (EID) is influenced by the characteristics of a firm's ultimate owners. Based on the EID of publicly listed firms in China, we qualitatively measure the quality of EID of each firm and link those quality scores to firm characteristics to understand the determinants of EID. We further link the EID scores to market valuation of the firm through the Ohlson valuation model to understand whether the market appreciates EID. Our results show that EID is more likely for government‐controlled firms, firms with less hierarchy in their ultimate ownership and firms with more discrepancy between voting rights and cash flow rights. Our results also indicate that the stock market appreciates environmental issues and that EID itself, as well as disclosure quality, is associated with a higher market valuation. Our results still hold with the endogeneity issue controlled.

微生物防腐剂在食品保鲜上应用

随着科技的发展,食品工业也得到快速发展,食品保鲜是食品界十分关注的问题。在食品保鲜中常用的微生物防腐剂是一类由微生物产生的食品防腐剂,它能抑制微生物的生长或直接杀死微生物,是一种天然、安全、高效的防腐剂,在食品保鲜界的应用越来越广泛。本文首先分析微生物防腐剂的种类,然后具体介绍了在食品保鲜中使用最广泛的乳酸链球菌素和纳他霉素的具体应用,对于微生物防腐剂在食品保鲜上的应用有很强的现实意义。     

Does telic/paratelic user mode matter on the effectiveness of interactive internet advertising? A reversal theory perspective

Drawing on reversal theory (Apter, 2007), the current research proposes that internet users' metamotivational state (telic vs. paratelic) determines advertising interactivity's effectiveness. An online field experiment involving 141 Facebook and Twitter users tests this proposition. Research findings support telic state consumers form more positive attitudes toward a low-level interactive ad, whereas paratelic state consumers form more positive attitudes toward a high-level interactive ad. Further, this research shows that an arousal seeking tendency mediates the metamotivational state's impact on ad attitude.

Assessing the Impact of District Primary Education Program in India

We examine the impact of India's District Primary Education Program (DPEP) introduced in the mid‐1990s. We exploit the fact that the DPEP was targeted towards primary school age children and was introduced in phases to different districts in India, and many of the districts never got the program to implement a difference‐in‐difference strategy to find the causal impact of the program on probability of attended primary school, probability of completed primary education and years of schooling. We find that the DPEP program increased the probability of attended primary school and completed primary school by about 2 percentage points. Similarly, the program increased the years of schooling by 0.16 years.     

企业政治关联对风险投资引入方式的影响

从资金需求方出发，以2009年10月至2016年12月深圳创业板和中小板首次公开上市的公司为样本，实证检验了政治关联对风险投资引入方式的影响，以及激励机制和监督机制这两种公司治理机制的调节作用，得到结论如下：政治关联企业倾向于在发展后期引入风险投资；政治关联企业倾向于选择国有性质、经验丰富以及参与程度高的风险投资机构；激励机制会加强政治关联企业在发展后期引入风险投资以及选择国有性质、经验丰富、参与程度高的风险投资机构的意愿；监督机制会减弱政治关联企业在发展后期阶段引入风险投资以及选择国有性质、经验丰富、参与程度高的风险投资机构的意愿。结论对拓展政治关联与风险投资领域的理论和实践具有重要启示意义。
