股票股利变化市场反应的实证研究

对公司分配方案中股票股利发生变化时股票收益率的研究,显示证券市场对股票股利分配方案发生变化时有一定反应,但与国外成熟资本市场的反应并不一致,说明我国证券市场距离国外成熟资本市场还有一定差距,证券市场信息披露制度尚不规范。     

养老保险体系的两种模式与社会经济因素关系比较分析

本文分析了现收现付和基金积累两种不同养老保险模式与人口老龄化、社会经济增长、通货膨胀、储蓄等社会经济因素之间的关系。经济的增长情况以不同的方式对现收现付模式和基金积累模式产生影响:对现收现付模式来说,如果经济增长缓慢,未来就业者的养老金负担就会增加,其效果与老龄人口在总人口中的比重增大一样;对于基金积累模式而言,如果经济的增长缓慢,那么在长时期内,利率就会处于一个相对较低的水平,这是不利于养老基金的有效增值,未来退休者的养老金收益就会减少。与现收现付模式相比,基金积累模式能带来一个更高的储蓄水平。     

土地红利公共利益属性的现实基础与保障机制

中国土地红利是经济红利和政策红利共同缔造的特殊红利形式,彰显土地红利公共利益属性是社会公平正义的内在要求。从逻辑上分析,我国土地红利源于土地公有制基础上的一系列制度安排,城镇化和工业化、土地用途管制、土地区位优势、公共投资等因素共同推高了土地价格,奠定了土地红利公共利益属性的坚实基础。为维护土地红利的公共利益属性,国家一方面将其纳入公共财政范畴,以规范公共财政收支的方式实现土地收益“全民共享”,防止土地红利被少数人垄断。另一方面,通过完善相关制度,改进土地收益的税法体系,科学界定房地产开发相关税收的税基和税额;健全土地征收制度,确保征地的目的、程序、收益合法且符合公益;推进土地红利城乡间公平分配,协调公共利益与个人利益的关系,实现土地红利共享。     

数字普惠金融与农户相对贫困脆弱性*

测度不同贫困线标准下数字普惠金融对农户相对贫困脆弱性的作用效果及其最优指数区间,揭示数字普惠金融对不同农户相对贫困脆弱性影响的结构性差异和作用机制。研究发现:数字普惠金融对农户相对贫困脆弱性的影响既存在"数字红利"效应也存在"数字鸿沟"效应,二者呈现出倒"U"型关系,降低农户相对贫困脆弱性的最优数字普惠金融指数区间位于108~160之间。分结构看,较低贫困线标准下数字金融覆盖广度对农户相对贫困脆弱性的减缓程度更加明显,但较高贫困线标准下数字金融使用深度对农户相对贫困脆弱性的减缓程度更大,且呈小幅递增趋势。在作用机制层面,数字普惠金融主要通过提高农户数字技能和风险管理能力,降低居民收入差距来发挥中介作用,减缓农户相对贫困脆弱性。     

国有资本收益收取政策对央企上市公司现金股利影响研究

自2007年国务院出台中央企业国有资本收益收取办法以来,经过2010年和2014年的连续调整,国有资本收益收取初步形成了一套制度体系,影响力也在不断扩大。在这样的背景之下,央企上市公司的现金股利政策是否受到国有资本收益收取政策的影响、国资收益收取比例是否合理值得进一步探究。基于代理理论对国有资本收益收取政策和上市公司现金股利政策的关系进行了理论分析并提出研究假设。研究结果表明,上市公司现金股利政策不仅受到传统的公司特征以及公司内部治理特征因素的影响,还受到宏观政策的制度因素的影响。     

Optimal financing and dividend policy with Markovian switching regimes

This work investigates an optimal financing and dividend problem for an insurer whose surplus process is modulated by an observable continuous-time and finite-state Markov chain. We assume that the insurer should never go bankrupt by issuing new equity. The goal of the insurer is to maximize the expected present value of the dividends payout minus the discounted cost of equity issuance. We obtain the optimal policies and explicit expressions for the value functions when the risk reserve process is modeled by both upward jump model and its diffusion approximation. Numerical illustrations of the sensitivities of the model parameters are provided.     

Can the minimum living standard guarantee scheme enable the poor to escape the poverty trap in rural China?

The rural Minimum Living Standard Guarantee (Dibao) Scheme is the most important social assistance programme in rural China. However, how the rural Dibao programme affects household expenditures and whether it can enable the poor to escape the poverty trap are questions that remain largely unexplored. This study used data from the 2012 Rural Household Survey in China to investigate the impact of the rural Dibao programme on household expenditures. We found that the programme significantly improved the well‐being of low‐income households. Particularly, the programme significantly increased household expenditures on housing, education and health; furthermore, the impact was greater for households with educated household heads. However, the programme did not significantly affect household expenditures on food, transportation or farming inputs. The results imply that participation in the rural Dibao programme induces household investment in human capital, which could help to break the inter‐generational transmission of poverty and raise long‐run welfare.     

The turn to optional familialism through the market: Long‐term care,cash‐for‐care,and caregiving policies in Europe

Cash‐for‐care (CfC) schemes are monetary transfers to people in need of care who can use them to organize their own care arrangements. Mostly introduced in the 1990s, these schemes combine different policy objectives, as they can aim at (implicitly or explicitly) supporting informal caregivers as well as increasing user choice in long‐term care or even foster the formalization of care relations and the creation of care markets. This article explores from a comparative perspective, how CfC schemes, within broader long‐term care policies, envision, frame, and aim to condition informal care, if different models of relationships between CfC and informal care exist and how these have persisted or changed over time and into which directions. Building on the scholarly debate on familialization vs. defamilialization policies, the paper proposes an analytical framework to investigate the trajectories of seven European countries over a period of 20 years. The results show that, far from being simply instruments of supported familialism, CfC schemes have contributed to a turn towards “optional familialism through the market,” according to which families are encouraged to provide family care and are (directly or indirectly) given alternatives through the provision of market care.     

From the Digital Divide to the Connectivity Dividend Difference: A Connectivity Capital Perspective*

The access divide was once the basic form of the digital divide. The development of Internet infrastructure has narrowed the access divide and increased application coverage, but it has also touched off a connectivity dividend difference. Taking the online market as an example, we examine the sources of the dividend difference and the factors influencing it with in a connectivity framework. We found that the narrowing of the access divide has resulted in enhanced connectivity and platform development, giving people the chance to benefit from transforming the various assets in which they have previously invested into differentiated compound connectivity capital. In the course, the scale and rate of the conversion are affected by two multiplier effects and especially by online platforms. The process is ultimately expressed in the dividend difference.     

Causal structure among US corn futures and regional cash prices in the time and frequency domain

This study investigates causal structure among daily Chicago Board of Trade corn futures prices and seven regional cash series from Iowa, Illinois, Indiana, Ohio, Minnesota, Nebraska, and Kansas for January 2006–March 2011. Their wavelet transformed series are further analyzed for causal relationships at different time scales. Empirical results indicate no causality among states or between the futures and a cash series for time scales shorter than one month. As scales increase but do not exceed a year, bidirectional causal flows are determined among all prices. The information leadership role of the futures against a cash price is identified for the scale longer than one year and raw series, at which no interstate causality is found.
