The 2015 welfare reform of the National Basic Livelihood Security System in South Korea: Effects on economic outcomes

In July 2015, South Korea’s National Basic Livelihood Security System (NBLSS) was reformed for the purposes of eliminating welfare blind spots and reducing poverty. The reform is expected to affect the recipients’ economic behaviours and choices. In this study, we used changes in benefits and eligibility for the NBLSS under the customised benefit system to identify the effects of the change in the NBLSS on a proposed set of economic outcomes – income, labour supply, consumption, savings, poverty reduction. To estimate the effects, we used data from the 10th–12th waves of the Korea Welfare Panel Study and employed a difference‐in‐differences framework integrated with the propensity scores. We found that the NBLSS helps the poor to reduce financial and material hardships through income and consumption increments, but that it does not provide disincentives to the recipients from participating in the labour market or from saving.     

Does the β-measure make empirical sense? A vignette experiment on humans’ judgment of social dominance

Dominance hierarchies play an important role in governing the social interactions of humans and other species of social animals. In a social group, dominance relations can be inferred from the directed network of matchups between actors. Methodologists have proposed different ways to measure social dominance in directed networks. One such measure, the “β-measure” (van den Brink and Gilles, 2000), emphasizes the quality of defeated opponents in a way that an actor is seen as being more dominant when s/he defeats opponents who are more rarely defeated. While insightful in theory, the validity of the measure in people’s perception remains questionable, considering the cognitive complexity imposed by this measure, compared to a simpler measure that merely counts the number of defeated opponents. We conducted a vignette experiment with human subjects (professional athletes) to test their judgments of the dominance relation in a hypothetical tournament. Fitting our parametric model to peoples’ evaluations in the experiment, we found strong evidence in support of the β-measure: Although, in general, contestants who win more in the tournament are regarded as being more dominant, the contents of the winning records matter, such that those who beat more victorious opponents are further regarded as more dominant than those who defeat less victorious opponents. We also found a gender difference, in that men have a stronger propensity than women to adopt the β-measure when judging social dominance.     

城镇企业职工基本养老保险基金支付能力预测研究

随着人口老龄化进程的加剧。我国城镇企业职工基本养老保险基金收支出现了巨大缺口并呈现逐步扩大的趋势,导致基金支付能力持续下降。本文应用社会保障精算方法与技术,以社会养老保险现行政策为导向。引入2005年颁布的《国务院关于完善企业职工基本养老保险制度的决定》中新养老金计发办法的经济参数。构建城镇企业职工基本养老保险基金收入与基金支出测算模型,其中以2006年新政策实施年为时间界限。分别构建“老人”、2006年前退休的“中人”（“老中人”）、2006年后退休的“中人”（“新中人”）、“新人”四类群体的基本养老保险基金支出洲算模型。从而推导出城镇企业职工基本养老保险基金支付能力预测精算模型。以期对养老保险基金失衡风险和支竹能力危机进行及时预测。并为社会养老保险政策调整和制度完善提供量化依据。     

财政扶持政策对西部地区农民参加新农村合作医疗的影响——基于自然实验的研究途径

本文将对西部农民参加新农村合作医疗的财政扶持政策的实施作为一个自然实验,应用微观经济计量方法分析了财政扶持政策对西部农民参加新农村合作医疗的影响。研究结果表明,与2004年相比,2006年西部农民参加新农村合作医疗的概率增加了96.46%,说明针对西部农民参加新农村合作医疗的财政扶持政策作用效果显著。     

Social dilemmas: When self-control benefits cooperation

Individuals in a social dilemma may experience a self-control conflict between urges to act selfishly and their better judgment to cooperate. Pairing a public goods game with a subtle framing technique, we test whether perception of self-control conflict strengthens the association between self-control and cooperation. Consistent with our hypothesis, cooperative behavior is positively associated with self-control in the treatment that raised the relative likelihood of perceiving conflict, but not associated with self-control in the treatment that lowered the likelihood. These results indicate that it is important to understand the role of self-control in cooperation.
