农民对宅基地权利认知及影响因素研究*——以河北省新乐市为例

［目的］通过对河北省新乐市农民在宅基地权力认知及影响因素方面的分析，探究我国农村宅基地制度并提出相关建议。［方法］文章受制度功能可信度理论启发，以河北省新乐市14个行政村为调研对象，探究农民对宅基地相关权利认知情况，同时采用Spearman相关性分析研究影响农民宅基地认知的因素。［结果］调研地自发宅基地流转市场已形成，宅基地制度功能处于社会保障功能向财产功能转变的过渡阶段； 农民对宅基地所有权认知不明晰，但并不影响宅基地市场建立； 在宅基地流转中，农民更关注相互之间信任、村委会保留的记录、流转中形成的“事实产权”； 农民性别、年龄、受教育水平和家庭人口数是影响权利认知的主要因素。［结论］依据制度功能可信度理论充分考虑宅基地制度在现阶段的功能变化，因地制宜； 政府应关注农民的宅基地使用权问题，使其真正成为农民的财产； 应对农村宅基地流转中形成的事实产权逐渐正式化； 应制定年轻人就业帮扶和年长者社会保障等相关政策，避免宅基地流转影响农村社会稳定性。     

The cost of firms’ debt financing and the global financial crisis

We provide an assessment of the determinants of the risk premium paid by non-financial corporations on long-term bonds. By looking at 5500 issues over the period 2005–2012, we find that in recent years the sovereign debt market turbulence has been a major driver of corporate risk. Compared with the three-year period 2005–2007 before the global financial crisis, in the years 2010–2012 Italian, Spanish and Portuguese firms paid on average between 70 and 120 basis points of additional premium due to the negative spillovers from the sovereign debt crisis, while German firms received a discount of 40 basis points.     

认知方式差异与英语阅读的因材施教

个体差异是影响教学活动的一个重要因素。在学习过程中共性和个体差异之间寻求一种合理、有效的途径一直是教学研究的重要内容。教师应了解学生的认知方式及其特点并因势利导,以提高学生英语阅读能力。     

上市公司财务虚假的成因--基于股东投票权完备性角度的研究

我国上市公司财务虚假的主要表现形式有利润操纵、利益转移、借关联交易调控损益以及少分配和不分配现金股利。而大股东投票权的非完备性:拥有股权的不可交易性,成为上市公司财务虚假的根本原因。     

勤工助学对贫困大学生职业心理的影响研究

采用实验组、对照组前后测对比方法,研究勤工助学对贫困大学生职业心理的影响。上岗前,实验组与对照组不存在显著差异;但上岗3个月后,存在显著差异。勤工助学是改变贫困大学生职业心理的有效手段。

Financial risk exposure of returns to education: Panel evidence from Korea*

The present study examined financial market risk exposure of human capital returns, which are represented by the returns to education, using panel data for Korea. Overall, financial market shocks seem to be irrelevant to returns to education. However, when we divide a financial market shock into cash flow news and discount rate news leading to a negative risk premium, returns to education increase after positive news about future cash flows and unexpected increases in discount rates Therefore, the risk exposure to cash flow shocks is offset by the exposure to discount rate shocks. The returns to education of low‐income workers were significantly exposed to the cash flow risk as compared to those with a high income, but they were offset by the positive correlation to discount rate shocks. In contrast, considering the gap between generations, the old generation was not only less exposed to the cash flow risk compared to the young generation regarding returns to education but also positively correlated with the discount rate shock, resulting in less exposure to financial market risks.     

Too big to fail: Measures,remedies, and consequences for efficiency and stability*

This paper evaluates whether reform efforts addressing “too big to fail” actually enhance the stability of the financial system, and whether trade‐offs exist between stability and efficiency. We also present and discuss various measures of bank size and complexity since such measures are essential for implementing appropriate corrective remedies. As we will show, there are no unambiguous measures of size or complexity that can fully capture a bank's contribution to systemic risk. Their effects on efficiency are also impossible to capture with certainty. While we recognize the need for additional research and empirical evidence, we do identify weaknesses and strengths of proposed and implemented reforms that could have consequences for bank stability and efficiency.     

On dividends in the phase–type dual risk model

The dual risk model assumes that the surplus of a company decreases at a constant rate over time, and grows by means of upward jumps which occur at random times with random sizes. In the present work, we study the dual risk renewal model when the waiting times are phase-type distributed. Using the roots of the fundamental and the generalized Lundberg’s equations, we get expressions for the ruin probability and the Laplace transform of the time of ruin for an arbitrary single gain distribution. Then, we address the calculation of expected discounted future dividends particularly when the individual common gains follow a phase-type distribution. We further show that the optimal dividend barrier does not depend on the initial reserve. As far as the roots of the Lundberg equations and the time of ruin are concerned, we address the existing formulae in the corresponding Sparre-Andersen insurance risk model for the first hitting time, and we generalize them to cover also the situations where we have multiple roots. We do that working a new approach and technique, approach we also use for working the dividends, unlike others, it can be also applied for every situation.     

异质性机构投资者差异化作用于双元创新投资吗 ——基于注意力基础观与市场迎合理论双重视角

基于2011-2020年沪深A股高新技术企业样本,探究公司治理框架下异质性机构投资者对企业双元创新投资的差异化作用机理,得出如下结论：①异质性机构投资者对于双元创新投资具有差异化影响,其中,专注型机构投资者更有利于双元创新投资;②专注型机构投资者影响决策者注意力资源配置,使其更注重探索性创新投资,临时型机构投资者基于市场迎合动机作用于开发性创新投资,且当管理层业绩和外部监管压力较大时,其对开发性创新投资的迎合动机更明显;③专注型机构投资者通过监督和激励管理层、提升企业风险承担水平作用于企业双元创新投资,临时型机构投资者通过丰富投资者情绪作用于开发性创新投资未得到验证;④产业政策有助于增强专注型机构投资者对决策者注意力的影响,使其更专注于探索性创新投资,同时也有助于提高临时型机构投资者的开发性创新迎合投资动机。研究结论为理解机构投资者差异化治理角色提供了一种新视角。
