AN EMPIRICAL ESTIMATE OF THE RELATION BETWEEN TWO MEASURES OF ECONOMIC WELFARE*

The main objective of this paper is to explore and quantify the difference between two measures of comparative economic welfare: (a) the more or less conventional measure of per capita national income, and (b) the capitalized value of expected future income per capita. The paper begins with a brief summary of the argument in favor of the present value of expected future income per capita as a measure of economic welfare. This is followed by an examination of the empirical relationship of the ratio of the suggested alternative measure to per capita income and an analysis of the variables used to compute the present value of expected income per capita. The main conclusion drawn from the calculations is that very substantial differences occur in the measurement of relative economic well-being depending on which measure is used. A final section discusses the implications of this finding for international comparisons of economic welfare.     

THE INCOME UNIT AND THE ANATOMY OF INCOME DISTRIBUTION*

This paper focuses on a neglected aspect of the treatment of the income unit in the construction of size distributions of income. If the size distribution is to be an indicator of the distribution of economic welfare, and if the economic welfare of each individual in society is to count equally, then conventional distributions are inconsistent with individualistic welfare functions. We estimate size distributions with each person's welfare weighted equally, and contrast these results with those weighting each household unit's welfare equally. The choice of weights is shown to affect both the level and the trend in income inequality.     

Health investment, saving, and public policy

Abstract.  This paper develops an overlapping‐generations model in which agents invest in health to prolong life in both working and retirement periods. It explores how unfunded social security with or without health subsidies affects life expectancy, economic growth, and welfare. In particular, by extending life at a possible cost of capital accumulation, health subsidies and a pay‐as‐you‐go pension can improve welfare, especially in the short run.

ENDOGENOUS HEALTH CARE, LIFE EXPECTANCY AND ECONOMIC GROWTH

We study the endogenous relationship between health care, life expectancy and output in a neoclassical growth model. Although health care directly diverts resources away from goods production, it prolongs life expectancy, which in turn leads to higher savings and, hence, capital formation through a private annuity market. We show that savings and health care are complements in equilibrium, with both rising with economic development. Our model is therefore consistent with several observed stylized development patterns across countries. Moreover, through the longevity-enhancing channel, health care and health production technology are found by simulation to be growth and welfare promoting.     

TRUE HOUSEHOLD EQUIVALENCE SCALES AND CHARACTERISTICS OF THE POOR IN THE UNITED STATES

In this paper we deal with the question of which measures of economic well-being are adequate to identify those groups of households in the U.S. whose economic conditions justify public concern and assistance. We derive a utility based measure of economic well-being from the estimation of a complete set of consumer demand equations. The demand system is Lluch's Extended Linear Expenditure System (Lluch, 1973). Household characteristics are incorporated using the scaling method proposed by Barten (1966). Using the welfare indicator derived, we study the composition of the poorest part of the population, using data from the 1972–73 Consumer Expenditure Survey. We compare our results with those obtained using various other welfare indicators, including the official U.S. poverty line. We show that using different family composition adjustments significantly and systematically affects just who are considered to be at the bottom of the welfare distribution. We finally suggest that program designers therefore can improve their target efficiency by carefully selecting from among the acceptable indices of welfare when defining program eligibility.     

WELFARE ECONOMICS AND THE MEASUREMENT OF NNP*

Some relationships between NNP and economic welfare are explored in the confines of a simple, static welfare maximization model. Various assumptions concerning both the measurement of NNP and the economic system underlying this model are dropped seriatem and the implications for the correspondence between NNP and economic welfare are examined. The following conclusions emerge. There are several classes of resource reorganization in which NNP and welfare move in the same direction, so that NNP can serve as an ordinal proxy for welfare. These include changes in taxes or competitive imperfections which result in product substitution and movements along the transformation function. With a general qualification, NNP-welfare correspondence is preserved for allocative changes which affect the real costs and prices of goods included in NNP or of non-included goods in inelastic demand; changes in involuntary unemployment; and changes in technological externalities affecting producers. There are other cases where changes in NNP and welfare are not positively correlated. Included here are changes in real costs of non-included goods for which demand is elastic and changes in technological externalities imposed on consumers.     

THE SOCIAL SIGNIFICANCE OF INCOME DISTRIBUTION STATISTICS

In both political discussions and scientific literature the income distribution has come to occupy a central position for the consideration of social welfare and economic equalization. It has been assumed that an individual's income reflects his consumption opportunities and therefore his standard of living or economic welfare. The thesis of this paper is, however, that there are reasons for being quite pessimistic about drawing meaningful conclusions from income distribution data. As illustrated by the use of Swedish data, the distribution of income gives an extremely incomplete picture of the distribution of consumption for a wide variety of definitional and statistical reasons. The distribution of consumption, furthermore, cannot be transformed into a corresponding distribution of welfare, since there is no well defined concept of welfare. The treatment of public consumption in empirical analysis of the distribution of welfare also raises problems. The paper closes with the presentation of the conceptual basis for an alternative to the traditional method of analyzing the distribution of income.     

中国信贷歧视的福利成本*

国有企业与民营企业之间的信贷歧视是中国经济转型过程中所特有的现象。本文构建了一个具有信贷歧视的动态随机一般均衡模型,以计算中国信贷歧视的福利成本。计算结果表明,信贷歧视大约会使整体社会的福利损失增加62%,其原因在于信贷歧视加剧了民营企业的产出波动并进而放大了通胀波动。本文进一步对比了不同货币政策下的福利损失,发现信贷歧视均会产生福利成本。据此,本文认为信贷歧视必须予以破除,从而消除信贷歧视带来的福利成本。     

Health and the evolution of welfare across Brazilian municipalities

This paper describes the pattern of reductions in mortality across Brazilian municipalities between 1970 and 2000, and analyzes its causes and consequences. It shows that, as in the international context, the relationship between income and life expectancy has shifted consistently in the recent past. But reductions in mortality within Brazil have been more homogeneously distributed than across countries. We use a compensating differentials approach to estimate the value of the observed reductions in mortality. The results suggest that gains in life expectancy had a welfare value equivalent to 39% of the growth in income per capita, being therefore responsible for 28% of the overall improvement in welfare. We then use a dynamic panel to conduct a preliminary assessment of the potential determinants of these gains. We show that improvements in education, access to water, and sanitation seem to be important determinants of the dimension of changes in life expectancy not correlated with income.

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.     

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.     

预期寿命延长促进经济增长了吗 ——基于全球121个经济体的实证分析

随着社会进步和生活水平的不断提升,人口预期寿命逐渐延长,全球人口老龄化程度亦不断提高,但这并非意味着人口红利的消失。本文基于1996—2017年121个经济体的面板数据,使用动态面板GMM估计方法分析了预期寿命与经济增长之间的关系。实证研究发现：（1）预期寿命延长对经济增长具有促进作用;（2）纳入收入与预期寿命的交互项后,预期寿命显示出对经济增长的制约作用,而收入水平的提高则中和了这种制约作用,带来经济增长水平的提高;（3）不同性别的预期寿命对经济增长的影响具有异质性。基于此,本文从提高居民可支配收入与提高人力资本水平方面提出了相关的政策建议。     

Calculating the welfare costs of import restrictions in the imperfect substitutes model

This paper supplies equations for partial-equilibrium calculations of the welfare effects of tariffs and quotas when the imported good and the competing domestic good are imperfect substitutes in demand. The equations take into account the response of the price of the domestic substitute. Although other studies have acknowledged this response, they have failed to account for it in their welfare calculations. To demonstrate the importance of this response, it is shown how it affects the calculations for the welfare costs of tariffs and quotas on US imports of footwear. It is shown that ignoring the response of domestic prices leads to significant overstatement of the welfare costs of tariffs and significant understatement of the welfare costs of quotas for the industry.     

Social Security and the increasing longevity gap

Growth in overall life expectancy is straining the Social Security budget, and the gap in life expectancy between the rich and poor is widening. Motivated by these facts, this paper does four things. First, we develop a simple way to summarize the degree of progressivity in a Social Security system. Second, we show that growth in the life expectancy gap over the last few decades unwinds three-quarters of the progressivity of the Social Security system. Third, we develop simple reforms to Social Security that maintain the progressivity of the system and restore fiscal solvency. Fourth, we estimate the welfare effects of these potential reforms.     

中国产业层次对地区初次分配 福利水平的提升效应——基于省级面板数据的实证分析

本文利用1993-2009年的省级面板数据，构建地区初次分配福利系数和产业层次系数，通过实证方法研究产业层次对地区初次分配福利水平的影响。研究表明，产业层次与地区初次分配福利水平正相关，产业层次越高，初次分配福利水平越高,产业层次对初次分配福利水平具有提升作用。产业层次系数增长率与地区初次分配福利系数增长率呈现先降后升的U型规律。这种U型变化具有经济发展的阶段性特点和区域性特点。产业层次的进一步提升对西部和中部福利水平的改进更明显，现代服务业产值结构提升的福利效应将在东部和东北地区体现得更明显。     

发展经济学的本质特征与中国特色发展经济学的构建

当代西方发展经济学微观化把发展经济学研究引入歧途。发展经济学本质上属于宏观经济研究领域,主要研究方法是长期动态演变方法,主要研究思路是结构性和综合性分析。西方发展经济学无法解释当代中国经济发展问题,构建具有中国特色的发展经济学是历史的呼唤,时代的期盼。构建中国特色发展经济学应以历史唯物主义为指导,以中国特色社会主义理论体系为指南,以新发展理念为理论框架。     

The dynamics of financial development,globalisation, economic growth and life expectancy in sub‐Saharan Africa

The importance of life expectancy is recognised in the development economics literature because of its increasing effects on labour productivity and economic growth in long‐run. However, no published study to date empirically examines the nonlinear relationships between globalisation, financial development, economic growth and life expectancy in sub‐Saharan African (SSA) countries. Therefore, our study intends to fill this gap by using non‐parametric cointegration test and multivariate Granger causality test towards a non‐linear empirical understanding of the factors affecting the life expectancy. We consider the case of 16 sub‐Saharan African economies using annual data over the period 1970–2012. The empirical analysis indicates that financial development, globalisation and economic growth appear to have a positive impact upon life expectancy in sub‐Saharan African economies, except for Gabon and Togo. Our empirical findings may provide insightful policy implications towards improving population health conditions which are vital for promoting the productivity of labour force and long‐run economic growth in sub‐Saharan African countries. In light of these policy implications, governments should incorporate globalisation, financial development and economic growth as key economic instruments in formulating sustainable developmental policy to promote life expectancy for the people in sub‐Saharan African countries.     

WELFARE REFORM, EARNINGS, AND INCOMES: NEW EVIDENCE FROM THE SURVEY OF PROGRAM DYNAMICS

The authors ask how welfare reform has affected the earnings and incomes of welfare recipients using a detailed longitudinal data set, the recently released Survey of Program Dynamics (SPD). They find pre-TANF waivers positively affected the earnings and incomes of both female high school graduates and nongraduates, but the effect is statistically significant only for nongraduates. In contrast, the effect of TANF policies is detrimental to nongraduates but improves economic outcomes for graduates. The findings indicate there are still families who are left behind by welfare programs. The results also warrant further use of longitudinal data sets such as the SPD. (JEL I38 , H53 )     

EFFICIENCY EFFECTS OF CHANGES IN COMMONWEALTH GRANTS TO THE STATES: A CGE ANALYSIS*

This paper describes CSF, a general equilibrium model encompassing factors of relevance to economic efficiency in Federal/State funding including: interstate differences in tax bases and unit costs of State‐provided goods; factor mobility; congestion; State‐government behaviour incorporating the possibility that governments in subsidised States embark on expenditures with low benefit/cost ratios (flypaper effects); fiscal externalities; and non‐discretionary expenditures in each State associated with special national responsibilities. The model is applied to Australia where Federal/State funding is a major political and economic issue. Welfare effects of moving from the present Australian funding system based on fiscal equalisation to a system of equal‐per‐capita grants are calculated. CSF implies that the welfare gain from this move would be small. The most important source of potential welfare gain is a reduction in flypaper effects. The recognition of congestion externalities can eliminate the small welfare gain, but only under seemingly extreme assumptions. The results are not very sensitive to variations in assumptions concerning population mobility and fiscal externalities.
