损失规避与经济波动的福利成本研究

目前经济波动的福利成本研究均建立在基于消费的效用函数基础上,而引入收入波动后我们发现:收入波动导致的福利成本才是更为重要的因素。本文定义的偏好具有损失规避的特点,在比较温和的参数设定下,考虑了收入波动后得到的福利成本指标λ在1.4%—13.4%之间,比此前各种技术方法得到的λ值提高了1—2个数量级。采用中国转型期以来的统计数据,消除短期波动的福利效果等同于将消费的长期增长率再提高约0.25个百分点,这表明如能进一步稳定经济的运行,仍会带来可观的福利提升。     

PUBLIC EDUCATION, FERTILITY INCENTIVES, NEOCLASSICAL ECONOMIC GROWTH AND WELFARE

Using a simple overlapping generations model of neoclassical growth, we analyse the effects of both child allowances and the system of public education on the rate of fertility, the per capita income and the individual lifetime welfare. The essential message of the present paper is that developed countries plagued by below-replacement fertility and income stagnation may raise per capita income and the rate of fertility at the same time by increasing the public education expenditure rather than by resorting to child allowances. The latter, in fact, are found to be harmful for long-run neoclassical economic growth and, in contrast with the common belief, for the rate of population growth as well. Moreover, welfare analysis has shown the existence of a Pareto-efficient welfare-maximizing educational contribution rate.     

THE ECONOMIC WELFARE OF THE AGED AND INCOME SECURITY PROGRAMS*

This paper examines several nonmoney components of economic welfare in both a theoretical and an empirical framework, computes the distributional ranking of aged families arising from such a measure, and subsequently examines the target effectiveness of eleven programs of the U.S. federal government aimed at the aged. While the theoretical discussion attempts to cover all factors contributing to the economic welfare of the aged, the empirical measure is somewhat less comprehensive, excluding the value of nonmarket productive activities and leisure time as well as benefits derived from direct government expenditures and some in-kind transfers and taxes. The study makes use of a subsample of the 1967 Survey of Economic Opportunity data composed of all families with at least one aged member. Specific attention is devoted to dissaving from net worth, in-kind transfers, incidence of taxes, and intrafamily transfers. Government cash and in-kind transfers are found to constitute a third of the total measured economic welfare of the aged, and the impact of each of these programs is examined individually. As might be expected, public assistance and public housing are the programs of most benefit to the aged poor. Medicaid and Medicare are substantially less so, and Social Security is distributionally neutral. Such programs as unemployment insurance are of little benefit to the aged. Tax expenditures, finally, provide no benefits to even the lower half of the distribution.     

THE IMPACT OF ANTI‐TERRORISM EXPENDITURE ON ECONOMIC GROWTH AND WELFARE

This paper examines the effects of increasing anti‐terrorism expenditure on economic growth rate and social welfare. It is shown that: (i) spending the least amount possible on anti‐terrorism expenditure will lead to a maximum economic growth rate; and (ii) to achieve maximum social welfare, the government should allocate its budget to anti‐terrorism expenditure. The results shed light on why the US government has chosen to uphold and pursue its anti‐terrorism policies in recent years to present day.     

LIFE EXPECTANCY AND ECONOMIC WELFARE: THE EXAMPLE OF AFRICA IN THE 1990s

A formulation for incorporating Life expectancy information into empirical economic welfare calculations is presented. In an application analyzing the economic progress of the African continent during the 1990s due consideration of life expectancy factors substantially modifies the conclusions drawn from standard welfare calculations.     

TRADE LIBERALIZATION AND RACIAL ANIMUS

Since the year 2000, the number of recorded hate groups in the United States has increased by more than 50 %. Some argue that the strain caused by unemployment or other socioeconomic stressors can play a critical role in the prevalence of extremist groups and crimes. We examine whether a change in U.S. policy to normalize trade relations with China, which fueled a surge in import competition that led to higher levels of unemployment, affected the presence of hate crimes. Using a difference‐in‐differences model and an event‐study framework, we find that areas most exposed to import competition experienced an increase in the number of anti‐Black hate crimes. We also find a qualitatively similar effect on the number of active hate groups in response to import competition. This result holds pre‐ and post‐the Great Recession and is consistent across levels of aggregation. The results are consistent and robust to various controls and specifications.

我国通胀与经济增长放缓福利 成本的比较研究

经济理论和实践经验通常认为我国经济增长放缓的福利成本远高于通货膨胀的福利成本,因而“保增长”的重要性远高于“防通胀”。本文认为这一判断已经不再适用于我国当前情况,核心原因是当前家庭的财产积累水平较以往有了大幅度提高,通胀将通过财产再分配效应造成严重的社会福利损失。经过计算发现：在各组参数设定下,5%的通胀和经济增速下滑一个百分点所造成的社会总福利成本（对消费的补偿比例）分别平均是18%和59%;通胀福利成本与增长放缓福利成本之比平均为329%,相比之下,在不考虑财产再分配效应的计算方法中,该比例仅为约16%。这说明在中长期“保增长”和“防通胀”都具有重要的社会福利意义,因此宏观调控应该将二者都作为重要的政策目标。     

IMMIGRATION AND NATIVE WELFARE*

This article unifies two approaches for identifying the welfare and wage effects of immigration, one emphasizing the immigration surplus, the other stressing a potential welfare loss due to a terms‐of‐trade effect. We decompose the native welfare effect into a standard complementarity effect, augmented by a Stolper–Samuelson effect, and a terms‐of‐trade effect. We illustrate the welfare and wage effects of endogenous goods prices in a stylized‐specific factors model. Finally, we calibrate this model to a generic OECD economy and provide simulation results. The key insight is that endogenous goods prices play a quantitatively important role, sometimes even overturning received results.     

BUSINESS CYCLES AND RACIAL DISPARITIES IN PUNISHMENT

Deeply rooted historical patterns allow us to make a correlation between imprisonment and unemployment and the marginalization of blacks. This paper examines the interrelationships among criminal activity, punishment, and cycles of the economic system based on the influence of political and economic forces on forming penal policies. The penal system is viewed as a device by which labor market fluctuations can be regulated. We examine differences between blacks and whites and between the North and the South to arrive at this paper's thesis: that race provides the link among economic cycles, employment, and crime.     

INTEREST GROUPS, INFLUENCE AND WELFARE

This paper examines the social costs and benefits of special interest group political influence activities. It is commonly recognized that, to the extent that such activities induce legislators to choose policies that favor the interest group at the expense of society at large, they can reduce welfare. It may also be the case, however, that lobbying can convey information held by interest groups to policy-makers. When costless announcements would not be credible, interest groups can signal their private information through costly influence activities. To the extent that this information enables governments to choose better policies, lobbying can enhance welfare. A simple game between a special interest group and a policy-maker that captures this tradeoff between the distortionary costs and the informational benefits of political influence activities is developed. Welfare properties of the equilibria are analyzed, and conditions are derived under which social welfare is greater when lobbying occurs than it would be if lobbying were prohibited. In conclusion, the phenomenon analyzed in this paper is related to Bhagwati's taxonomy of DUP activities.     

TOURISM, TRADE AND DOMESTIC WELFARE

Abstract.  Tourism has been regarded as a major source of economic growth and a source of foreign exchange. It has also been viewed as an activity that imposes costs on the host country. Such costs include increased pollution, congestion and despoliation of fragile environments, and intra-generational inequity aggravation. One aspect that has been ignored is the general equilibrium effects of tourism on other sectors in the economy. This paper presents a model that captures the interdependence between tourism and the rest of the economy, in particular agriculture and manufacturing. An important result obtained is that the tourist boom may 'immiserize' the residents.     

逆周期的贸易政策与福利分配

2008年金融危机以来,全球逆周期的贸易政策盛行。为了探究逆周期贸易政策对双方福利分配的影响,本文在巴格维尔和斯泰格解释发达经济体之间逆周期贸易政策最优选择模型的基础上,构建了一个2×2×2模型,假定两国商品的需求价格弹性不同,首次在理论上证明了发达国家(如美国)和发展中国家(如中国)之间的逆周期贸易政策取向和福利分配,并依据经验数据证实了自由贸易政策对中美双方来说都是帕累托改进,但中国的福利增进水平低于美国的福利增进水平;而在逆周期贸易政策下,美国和中国通过贸易获得的福利增进水平之差进一步扩大。     

DEPRIVATION,INEQUALITY AND WELFARE*

Welfare ranking of income distributions involves a trade‐off between equity and efficiency. A person's feeling of deprivation about higher incomes may be of a relative or absolute type. We consider an intermediate notion of deprivation, a convex mix of relative and absolute deprivations. We then look at the problem of welfare ranking of income distributions when welfare increases under a globally equitable redistribution and under an income increase that keeps intermediate deprivation fixed. All deprivation indices can be regarded as inequality indices but the converse is not true. We also provide a numerical illustration of our results.

两种冲击视角下中国城乡经济波动福利成本研究*

经济波动福利成本的准确测算,一方面能够对经济波动根源的差异化理论做出评判,另一方面也直接关系到政府对于经济政策的选择。本文基于Lucas福利成本模型,采用BN分解公式对消费序列进行分解,估计了暂时性冲击和持久性冲击所造成的经济波动福利成本。本文研究证实,持久性冲击所造成的经济波动福利成本远大于暂时性冲击所造成的福利成本,避免不利供给因素所带来的持久性冲击,是增进城乡居民福祉的重要举措。这与当前所实施的“供给侧结构性改革”相契合。
