人口老龄化视角下家庭照料与城镇女性就业关系研究

随着我国人口老龄化,女性在家庭劳动与职业劳动之间的角色冲突日益凸显。文章利用1991-2009年"中国营养与健康调查"(CNHS)数据及面板数据分析和工具变量方法,实证检验了老人家庭照料责任对城镇女性职业劳动参与决策的影响,以期为女性就业、养老政策的制定提供科学依据。研究发现,照料老人显著降低了女性的劳动参与率,尤其是长时间、高强度的照料活动。与无照料责任的女性相比,与父母(公婆)同住、有照料责任的女性劳动参与率将下降0.215;高强度照料活动对女性劳动参与的影响更大,劳动参与率将下降0.695。     

From Generosity to Sustainability: The Austrian Pension System and Options for its Reform

Austria has one of the world's highest pension expenditures relative to GDP, largely because of the generosity of its pension system. This paper examines the institutional setup of the Austrian pension system and projects its medium- and long-term development based on current policies. The projection results show a swift worsening of the finances of the pension system. With the already high level of contribution rates, pension expenditures, and budget transfers, the results underscore the need for reform. Much of the necessary reform can, however, be achieved by maintaining the structure of the system and adjusting some of its key parameters, as begun in the recent pension accord. The paper outlines options for further reform steps.     

流动性与资产定价:基于我国股市资产换手率与预期收益的实证研究

流动性与资产定价是目前金融研究的热点之一 (O’Hara,2 0 0 3 )。本文通过检验交易频率零假设和交易成本备择假设 ,深入分析我国股市流动性与资产定价的理论与经验关系 ,发现 :我国股市存在显著的流动性溢价 ,换手率低、交易成本高且流动性小的资产具有较高的预期收益 ;产生流动性溢价的原因是交易成本而不是交易频率 ;与国外股市相似 ,小企业收益率高于大企业 ,价值股收益率高于成长股。因此 ,我国股市并非令人无法捉摸 ,流动性、规模和价值效应都是资产定价的因素     

Wealth Distribution and Imperfect Factor Markets: A Classroom Experiment

The author presents a simple exercise to demonstrate how initial property distribution can affect final wealth patterns in developing areas of the world. The simulation is a variant of the Monopoly board game in which students role play different members of a market in which they each face different rules of credit access and salary patterns. The property distribution and new mortgage rules reflect the reality of many developing areas. The simulation can be completed in one full class period and has proven successful in making students more sensitive to wealth distribution issues. Students have suggested several variations of this simulation to make it applicable across more settings.     

企业异质性、规模报酬与劳动力空间流动——基于新新经济地理学的理论研究

文章在对新新经济地理学假设进行拓展的基础上,从理论分析和数值模拟两个层面对企业异质性、规模报酬与劳动力空间流动进行了系统的研究,结论是:地区间企业生产技术水平的不同决定了企业与劳动力的转移方向,企业的生产技术水平与固定成本呈正向变动关系;落后地区和发达地区的发展与彼此对外市场开放相互依赖;由于落后地区总有一定的市场需求,棒—棒均衡在现实中存在的可能性很小。     

Labor supply: Toward the construction of an alternative conception from post Keynesian and institutional economics

Post Keynesian and institutional economics have traditionally maintained a critical stance toward the orthodox model of labor supply, questioning many of its underlying assumptions. Nevertheless, this critical view has not led to the formulation of an alternative conception of labor supply that is sufficiently coherent and structured to be generally accepted within these branches of the literature. Accordingly, the purpose of this study is to contribute to the construction of such an alternative. To do so, the article starts by analyzing the relationship between the reasons that lead to individuals offering their labor and what that activity can bring to human beings in return. Secondly, the authors present an alternative concept of what workers contribute at work. They then analyze how the decision-making process regarding the labor supply actually takes place. Finally, the article concludes by briefly presenting certain additional points, in particular how differentiation is an inherent feature of the labor supply.     

从民工潮到民工荒: 基于劳动力市场管制视角的分析

自2004年春开始,曾引起社会各界关注多年的民工潮逐步被以农民工短缺为特征的民工荒所取代.从民工潮到民工荒的转变绝不仅仅是表面上的农民工由富余到短缺,其实是一种使多层次矛盾得以凸显的劳动力市场现象.从劳动力市场管制角度看,民工荒现象凸显了我国劳动力市场管制中存在的制度缺陷和管制失灵;而要破解民工荒,改善对劳动力市场特别是农民工市场的管制,无疑是一种必然选择.本文从劳动力市场管制视角对民工荒现象所蕴含的社会意义、产生原因及解决对策做一分析.     

The Return to Caring Skills: Gender,Class, and Occupational Wages in the US

Feminist economics has contributed to the understanding of the economic importance of care work. Most studies find a wage penalty associated with caring occupations. This study extends the feminist research on care work beyond caring occupations by identifying specific caring skills and activities derived from the 2014 O*NET job-evaluation data. Four caring skills – (1) Assisting and Caring for Others, (2) Establishing and Maintaining Interpersonal Relationships, (3) Service Orientation, and (4) Social Perceptiveness – were used in ordinary least-squares and quantile wage regressions for 623 occupations in the United States. Findings indicate that the return to caring and assisting skills results in a wage penalty for low-wage workers but a wage premium for workers in high-wage and male occupations. By identifying the impact of gender and class on the economic return to particular caring skills, the study broadens the understanding of care work, especially in relation to US wage inequality.     

Primitive and Modern Economics: Derivatives,Liquidity, Value,Panic and Crises,A Uniformitarian View

This paper investigates aspects of economics in the context of complex society and the nature of investment devices in cross-cultural comparison, placing special attention on the new global issues of money, hedge fund contracts, derivatives and other risk-spreading concepts and practices. The function of these are compared to the behavior of the inventors and practitioners in other cultures. Similarities are noted with religious formulators and the process of conversion and the operation of the market and credit paralleled with the concept of Mana. This work provides a context for understanding contemporary human economic behavior. Novel structures of symbolic worth are associated with individual presentation and performance. Clearly concepts of value and credit have been changing in modern financial culture. Indeed, they have been expressing forms that have traditionally been associated with primitive economics. An understanding of the current financial and social losses resulting from the subprime collapse is presented along with a means to counter it.

中国经济改革:背景、机制与挑战

经过三十余年的经济改革,中国的经济取得了巨大的进步,中国这条巨龙也正在逐渐回归到她在世界经济中应有的位置。这种经济改革是如何成功的?本文认为,承接于特定的历史经济背景,中国经济中三类主要的行为主体(中央、地方、民众)根据自身的条件进行了事实上的互动式的协调分工,各自对既有的约束条件进行突破,并在互动演进的发展过程中逐步建立了新的规则,这些规则所确立的激励与约束极大地调动了各参与主体的积极性,实现了从事必躬亲到各司其职的职能转换。正是在这些过程中,中国经济逐渐得到发展并获得前所未有的成就。但我们同时强调,在经济改革的过程中,也必须认清体制的不足,积极应对新的挑战。     

Economic burden of hepatitis C-associated diseases: Europe,Asia Pacific,and the Americas

Abstract

Background:

Globally, hepatitis C virus (HCV) infects ～3% of the population. The objective of this study was to review published work and determine the direct medical costs for diseases associated with HCV infection globally, with the exception of the US.

Methods:

A systematic literature search was conducted to identify studies reporting the costs of hepatitis C sequelae between January 1990 and January 2011. Over 400 references were identified, of which 45 were pertinent. The costs were compiled, converted to US dollars, and adjusted to 2010 costs using the medical component of the consumer price index.

Results:

The median cost of liver transplants was estimated at $139,070 ($15,430–$443,700), refractory ascites at $16,740 ($8990–$35,940), hepatocellular carcinoma (HCC) at $15,310 ($3370–$84,710), decompensated cirrhosis at $14,660 ($3810–$48,360), variceal hemorrhage at $12,190 ($3550–$46,120), hepatic encephalopathy at $9180 ($5370–$50,120), diuretic sensitive ascites at $3400 ($1320–$7470), compensated cirrhosis at $820 ($50–$2890), and chronic hepatitis C at $280 ($90–$1860). The variation among studies was mainly due to the methodology used to assess cost, local cost and government reimbursement, and country-specific treatment protocols.

Limitations:

All costs were adjusted to 2010 US dollars using the US medical component of the consumer price index (CPI) which may not reflect the change in medical costs in other countries. In addition, the costs, in the local currency were converted to US dollars in the year of the study. However, medical expenses may not vary with exchange rate, leading to artificial variations. Finally, there was no assessment of the quality of individual studies, which resulted in the same weighting to all studies.

Conclusions:

Hepatitis C imposes a high economic burden globally. Knowing the burden of HCV sequelae is useful for policy decisions as well as serving as a basis for determining the value of HCV screening and treatment.

Taxes and labor supply: Portugal, Europe, and the United States

I relate hours worked with taxes on consumption and labor for Portugal, France, Spain, United Kingdom and United States. From 1986 to 2001, hours per worker in Portugal decreased from 35.1 to 32.6. With the parameters for Portugal, the model predicts hours worked in 2001 with an error of only 12 min from the actual hours. Across countries, most predictions differ from the data by 1 h or less. The model is not sensible to special assumptions on the parameters. I calculate the long run effects of taxes on consumption, hours, capital and welfare for Portugal. I extend the model to discuss implications for Social Security. I discuss the steady state and the transition from a pay-as-you-go to a fully funded system.

Unemployment and Labor–market Reform: A Contract Theoretic Approach

Why do many democracies fail to reform their labor–market institutions? To answer this question we study the feasibility of reforms that include compensation to insiders for the removal of labor–market regulations. Under asymmetric information, a reformer who wants to buy the approval of voters has to pay them an informational rent in addition to the pure costs of compensation that would arise under symmetric information. In this setting, unemployment may be constrained Pareto–efficient. Labor–market reforms may fail politically because none of the reform packages proposed wins the approval of a majority of voters. We also discuss the role of capital taxation in a reform program. JEL classification: D70; E61; J68     

老龄化、资源依赖与技术创新——基于全球跨国面板的实证分析

选取全球87个国家2000—2016年的数据,分析了老龄化与资源依赖如何对技术创新产生影响,并运用工具变量二阶段最小二乘法(2SLS)进行了实证检验。研究思路主要基于人力资本这一传导机制,通过计量模型也证实了人力资本在老龄化、资源依赖与技术创新间的传导作用。研究结果表明:老龄化对技术创新并非阻碍作用,反而会促进一国技术创新发展。然而,资源依赖与大多数研究结论一致,会对技术创新带来消极影响。全球各国应该提高资源利用效率,防范自然资源依赖对人力资本投资的挤出效应,并且应注重人力资本投资,应对日益严峻的老龄化现象,提高区域技术创新水平。     

Norms and Rationality in the Evolution of Economic Systems: A View from Asian Villages

The evolution of economic systems is viewed as a process in which various informal arrangements are experimented with for improving efficiency under changed economic environments, some of which may survive and become established as new social norms. The process is illustrated by a micro case study of Philippine villages. It reveals the ability of peasants subsisting on small farms to resolve a major disequilibrium between labour's marginal productivity and the wage rate resulting from the intro duction of modern rice technology, by creating, on the basis of their traditional experience, an appropriate institution consistent with their cultural norm. Concurrently, large estate farms were seen to arrive at an inferior outcome because of their inability to utilize the peasant community's norm, thereby demonstrating the existence of multiple equilibria

Financial Crisis,Capital Outflows,and Policy Responses: Examples from East Asia

Financial crises seem to have become the norm rather than the exception since 1992. The author examines the impact of a crisis of confidence and resultant capital outflows from a small and open economy and the possible policy options in response to such outflows, using simple tools and definitions that will be familiar to any money and banking or intermediate macroeconomics student. Examples are drawn from the East Asian crisis of 1997-98 (Indonesia, Korea, Malaysia, and Thailand), although the analysis remains pertinent to emerging economies in general.     

劳动力转移与工资差距同时扩大的“悖论”研究——基于市场分割的视角

从市场分割的角度出发,对劳动力流动与工资差距同时扩大的"悖论"和中国市场化过程中的"迁移谜题"进行了深入分析,认为劳动力市场的地区分割和城乡分割导致了劳动者之间必然存在工资收入差距,而且即使存在劳动力转移,也不能使工资差距收敛。这种制度性偏好导致的劳动力市场分割,对劳动者工资收入差距的扩大起了推波助澜的作用,因此构建全国统一、自由竞争的劳动力市场是非常必要的,并提出有关的政策建议。     

Perpetual youth and endogenous labor supply: A problem and a possible solution

In the “perpetual youth” overlapping-generations model of Blanchard and Yaari, if leisure is a “normal” good then some agents will have negative labor supply. We suggest a solution to this problem by using a modified version of Greenwood, Hercowitz and Huffman’s utility function. The modification incorporates real money balances, so that the model may be used to analyze monetary as well as fiscal policy. In a Walrasian version of the economy, we show that increased government debt and increased government spending raise the interest rate and lower output, while an open-market operation to increase the money supply lowers the interest rate and raises output.
