高技术企业多元化战略对创新持续性的影响——动态能力的调节作用

基于资源基础理论和持续创新内生机制，利用435家高技术企业2010—2018年面板数据，对多元化战略对高技术企业创新持续性的影响进行探究。结果表明，产品多元化与创新持续性呈正U型关系，技术多元化对创新持续性具有正向促进作用，产品多元化与技术多元化协同效应对创新持续性具有负向影响；动态能力强化了产品多元化与创新持续性之间的正U型关系，并正向调节技术多元化与创新持续性之间的关系。在动态能力调节作用下，高技术企业产品多元化与技术多元化协同效应对创新持续性具有正向影响。     

基于系统动力学的区域林业碳汇市场中三方主体利益行为演化博弈分析

分析影响三者策略行为的作用因素,构建区域林业碳汇市场的演化博弈模型。在此基础上,结合系统动力学理论,对广东省的碳汇发展状况进行仿真模拟,找出影响市场均衡发展的关键因素。结果表明:政府部门趋向于选择投入策略,其中提高市场碳交易额对拉动市场需求有显著影响,而增强对林农碳汇林的补贴力度难以解决市场当前供需问题。     

产业政策与上市公司并购重组溢价——基于并购重组委行政审核的经验证据

基于并购方视角的议价理论和被并购方视角的隐性获利理论,本文以我国2008～2018年并购重组委审核通过的中国沪深两市A股上市公司并购重组事项为样本,研究了产业政策对上市公司并购重组溢价的影响.研究发现,受产业政策支持的上市公司为并购重组事项支付了更低的并购溢价.进一步研究发现,当上市公司属于民营企业、所处市场化程度较高的地区时,受产业政策支持的上市公司为并购重组事项所支付的并购溢价水平也更低;另外,并购重组实现后,受产业政策支持的民企上市公司展现出了更高的股票回报率,隐性获利由此得以真正实现.本文的研究结论为上市公司和监管部门提供了重要的管理和政策启示.     

Emotions,deliberations, and end‐of‐life products

Death is inevitable; yet, not all consumers prepare for death by purchasing end‐of‐life (EOL) products. Using the theory of reasoned action (TRA) and the dual‐process model framework, this study aims to examine the role of emotions and cognitions in influencing consumers' decisions to engage in planning for death. A mixed methodology design was used. Study 1, a qualitative study, uncovered positive and negative emotions and deliberative reasoning that comprise consumers' EOL purchase decision process. Study 2, a quantitative study, confirmed that emotions and deliberations independently and jointly influenced consumers' EOL attitude and behavior and that emotions affected deliberations for both prepaid funerals and wills. Subjective norms outperformed attitude in predicting both products' purchase behavior. These finding supported the dual‐process model of behavior and the TRA in the EOL research context and contributed to the EOL literature by investigating the effects of emotions and deliberations concurrently; thus validating the important role of emotions in influencing EOL planning and purchase. In light of our findings, marketers could, after due cognizance of the morbidity and sensitivity of the topic, develop actionable promotional and segmentation strategies for EOL products and other emotion‐laden, unsought products and service.

Financial and Housing Wealth,Expenditures and the Dividend to Ownership

For a household, home ownership provides necessary shelter, potential investment returns associated with property appreciation and a hedge against increased housing related cash outlays. In addition to potential appreciation, individual households benefit over time from a housing dividend defined as the difference between the market rent for the individual household’s housing unit and the household’s actual house ownership costs. The purchase of a house can substantially fix a household’s recurring housing related expenditures and generates a hedge (implied housing dividend) that increases with ownership tenure. This expenditure hedge (dividend) to home ownership is documented using pooled, cross-year samples from the Consumer Expenditure Survey (CEX). The housing dividend delivers a non-trivial effect on household non-housing expenditures after controlling for housing value, housing equity, financial assets and income.     

Optimal insurance in the presence of reinsurance

This paper studies an optimal insurance and reinsurance design problem among three agents: policyholder, insurer, and reinsurer. We assume that the preferences of the parties are given by distortion risk measures, which are equivalent to dual utilities. By maximizing the dual utility of the insurer and jointly solving the optimal insurance and reinsurance contracts, it is found that a layering insurance is optimal, with every layer being borne by one of the three agents. We also show that reinsurance encourages more insurance, and is welfare improving for the economy. Furthermore, it is optimal for the insurer to charge the maximum acceptable insurance premium to the policyholder. This paper also considers three other variants of the optimal insurance/reinsurance models. The first two variants impose a limit on the reinsurance premium so as to prevent insurer to reinsure all its risk. An optimal solution is still layering insurance, though the insurer will have to retain higher risk. Finally, we study the effect of competition by permitting the policyholder to insure its risk with an insurer, a reinsurer, or both. The competition from the reinsurer dampens the price at which an insurer could charge to the policyholder, although the optimal indemnities remain the same as the baseline model. The reinsurer will however not trade with the policyholder in this optimal solution.     

Corporate Governance and the Investment Efficiency of Diversified Corporate Asset Buyers

Many corporate assets are bought and sold each year in the U.S. and most scholars believe these transactions improve economic efficiency. But given the reality that the interests of corporate managers may diverge from those of their shareholders and reflect empire‐building or other managerial entrenchment strategies—and that such agency problems tend to be worse in highly diversified, multi‐divisional companies—the authors tested the proposition that diversified corporate asset buyers with more effective governance structures can be expected to allocate capital more efficiently, as reflected in higher rates of return on operating capital and more favorable market reactions to the announcements of their purchases. Using a sample of diversified U.S. companies that announced large asset purchases between 1988 and 2006, the authors report finding that the investment allocation process following such asset purchases was more consistent with value creation in the case of diversified buyers with more effective governance structures, which were identified by their greater board independence, higher‐quality audit committees, and higher levels of stock ownership by institutional ownership, directors, and CEOs.
