Relative Wealth, Consumption Taxation, and Economic Growth

This paper examines the role of the relative wealth-induced status motive in affecting the neutrality of consumption taxation in an optimizing growth model. It is found that a key factor determining the validity of the neutrality of consumption taxation in both the level sense and the growth rate sense is the desire for relative wealth-induced social status. When individuals care about their relative wealth, a rise in consumption tax enhances the steady-state level of capital stock and consumption. Furthermore, if the production function takes a linear technology form as the engine of sustained growth, then increases in consumption taxation raise the economy's long-run growth rate. In addition, an optimal consumption tax policy provides full subsidies to consumption so as to induce the economy to achieve the social optimum and the optimal growth rate.     

Status,Risk-Taking and Intertemporal Substitution in an Endogenous Growth Model

This paper examines intertemporal risk-taking in a stochastically growing economy with externalities in human capital accumulation where agents have preferences for social status. In order to isolate the effects of status concerns on long-run expected growth, the analysis is embedded in a non-expected utility setting, which disentangles the effects from risk aversion and intertemporal substitution. We examine the interaction between status desire and risk, risk aversion and intertemporal substitution. The externalities generated by the status game are able to correct the allocative distortions from the knowledge spillovers.Acknowledgement The author would like to thank an anonymous referee for his valuable comments.     

Growth and income inequality: a canonical model

Summary. We develop an endogenous growth model with elastic labor supply, in which agents differ in their initial endowments of physical capital. In this framework, the growth rate and the distribution of income are jointly determined. The key equilibrating variable is the equilibrium labor supply. It determines the rate of return to capital, which in turn affects both the rate of capital accumulation and the distribution of income across agents. We then examine the impact of various structural shocks on growth and distribution. We find that faster growth is associated with a more unequal, contemporaneous distribution of income, consistent with recent empirical findings.Received: 7 October 2004, Revised: 18 February 2005, JEL Classification Numbers: O17, O40.Cecilia García-Peñalosa: Correspondence toGarcía-Peñalosa would like to acknowledge the financial support received from the Institut d’Economie Publique (IDEP), Marseille.

Status Aspirations, Wealth Inequality, and Economic Growth

This paper argues that an increase in the inequality of wealth prompts a stronger quest for status that in turn fosters the accumulation of wealth. It proposes a measure for an individual's want of social status. For a given level of a population's wealth, the corresponding aggregate measure of want of social status is shown to be positively related to the Gini coefficient of wealth inequality. Hence, the Gini coefficient and growth are positively correlated, holding the population's wealth constant.     

Income Distribution, Redistributive Politics, and Economic Growth

This article studies the political economy of inequality and growth by combining the political economy approach with an imperfect capital market assumption. In the present model, there emerges a class of individuals whose members do not invest privately beyond the state-financed schooling, due to their initial wealth constraint. We show that inequality affects private investment not only through the political effect, which relates inequality to private investment negatively, but also through what we call the threshold effect, which associates inequality to private investment positively. In general, private investment and inequality do not show a monotone negative relationship.     

经济增长、财富分配与缓解贫困

随着人们对贫困内涵、贫困的性质和原因的认识日益加深,反贫困战略也从片面强调经济增长向经济增长与公平分配并重的方向转变。换句话说,反贫困战略日益重视效率与公平的统一。有效的反贫困战略是:既实现惠及贫穷人的经济增长,又实现有利于经济增长的再分配;而增加贫穷人的受教育机会,提高其知识水平,使贫穷人享受基本的医疗保健,改善其健康状况,解决穷人的基本生活需要,改善其营养条件,是再分配战略的重要内容。     

内生增长框架下的中小企业和我国经济增长稳定

稳定中国经济高速增长的措施除了扩大国内需求之外,还可以从供给的角度考虑中小企业的作用。中小企业在国民经济总量中的重大贡献和中小企业内部管理不足的矛盾是影响我国经济增长趋于不稳定的一个重要因素。理论和实证分析结果表明,企业家知识溢出能力是决定企业私人知识边际产出的重要因素,中小企业主缺乏企业家的知识溢出能力是导致人均产出份额低于总量产出份额的主要原因。本文结论是我国要加大中小企业内部管理投入,促进中小企业主向企业家的实质性转变,提高中小企业主的知识产出能力,用以提高中小企业资源的使用效率,从而提高我国要素的整体使用效率,最终为稳定我国高速经济增长提供一个长远动力。     

Conflict, Distribution and Population Growth

This paper studies an optimal foraging model where distributive conflicts among foragers emerge from population growth. It investigates distributive rules set to resolve the conflicts. Efficient distributive rules are the ones associated with the most efficient productive decisions. Unequal societies, where the ruling class or King maximizes the surplus, engender the choice of more efficient productive combinations and to a smaller population relative to egalitarian societies.     

Democratic Choice of an Education System: Implications for Growth and Income Distribution

We use an OLG model to examine democratic choice betweentwo modes of government support for education: subsidies forprivately purchased education and free uniform public provision.We find little conflict between democracy and growth: the samefactors that generate popular support for subsidization overfree uniform provision—large external benefits, a largeexcess burden, and little inequality—also favor its relativegrowth performance. Furthermore, restricting the franchise toan upper-income elite may also reduce growth. Two extensionsexamine the effect of intergenerational mobility and indicatethe theoretical possibility of periodic swings in the balancebetween public and private spending.     

Matching, Heterogeneity, and the Evolution of Income Distribution

This paper analyzes a model in which firms and workershave to engage in costly search to find a production partner,and endogenizes the skill, job, and wage distributions in thiscontext. The presence of search frictions implies that thereare two redistributive forces in the labor market. The firstis mismatch relative to the Walrasian economy; skilled workerstend to work with lower physical to human capital ratios, andthis compresses the earnings differentials. The second is theopportunity cost effect; because the opportunity cost of acceptingan unskilled worker, which is to forgo the opportunity to employa skilled worker, is high, unskilled wages are pushed down. Theinteraction between these two forces leads to a non-ergodic equilibriumprocess for wage and income inequality. Further, the presenceof mismatch reduces the rate of return to physical capital andthus depresses growth. A key prediction of the analysis is thatincreasing wage inequality is more likely to arise in economieswith less frictional labor markets, which is in line with thediverse cross-country patterns observed over the past two decades.Finally, the paper predicts that, as is largely the case withU.S. data, between group and within group wage inequality shouldmove in the same direction.     

Economic Growth, Inequality, Democratization, and the Environment

We augment the Stokey (1998) model by allowingagents to differ with respect to environmentalquality and income in order to analyze theimpact of income and environmental inequality,and of democratization on aggregate pollution.We find that the impact of a more equal incomedistribution depends on the degree ofdemocracy. In a complete democracy a more equalincome distribution generates, ceterisparibus, less pollution, which is consistentwith indirect empirical evidence, whereas theopposite is the case if democratic rights arehighly restricted. Furthermore, ademocratization is argued to typically lowerboth the income and the environmental qualityof the median voter. In this case, if, inutility terms, the fall in environmentalquality is worse than the fall in consumptionthe median voter decides to tightenenvironmental legislation so that aggregatepollution decreases.     

金融发展、资本积累与内生增长:一个评述

本文以资本外溢AK内生增长模型为基础,对金融发展、资本积累与经济增长关系的理论研究和经验分析作了一个文献综述.理论研究表明:金融发展通过提高储蓄转化为资本比率、改善投资配置效率和改变储蓄率等途径促进资本积累和经济增长;金融发展与经济增长之间呈互相促进、互为因果的双向关系,并形成金融发达、经济高增长和金融欠发达、经济低增长的双重均衡.经验分析显示,金融发展与经济增长之间呈显著正相关关系,这证实了金融发展与内生增长理论的预测.     

经济增长与马克思主义视角下的收入和财富分配

本文构建了一个理论模型,试图应用马克思经济学的基本原理和方法研究当前资本主义生产方式下收入和财富分配不均等的形成机制,以及这种分配不均等和经济增长的关系。本文的分析框架具备了马克思主义经济学的主要特征,包括阶级分析、劳动价值论和资本雇佣劳动等,又结合了当代资本主义经济制度的某些特征,放宽了现有文献中"工人阶级无任何储蓄"的假设,所得到的结论可以在一定程度上解释1940年以来以美国为代表的发达资本主义国家的财富和收入分配情况,对于分析我国在社会主义初级阶段、多种所有制并存、多种分配方式并存条件下收入和财富分配不均等问题的成因和治理也有借鉴意义。     

Evaluating Patterns of Income Growth when Status Matters: A Robust Approach

This paper addresses the problem of ranking growth episodes from a microeconomic perspective. While most of the existing criteria, framed in the pro‐poor growth tradition, are either based on anonymous individuals or are used to identify them on the basis of their status in the initial period, this paper proposes new criteria to evaluate growth, which are robust to the choice of the reference period used to identify individuals. Suitable dominance conditions that can be used to rank alternative growth processes are derived by means of an axiomatic approach. Moreover, the theoretical results are used to rank the different growth episodes that have taken place in the past decade in Australia, Germany, Korea, Switzerland, and the U.S.     

R＆D、R＆D溢出、内生增长和内生收敛

根据强调知识与技术创新、知识与技术溢出重要性的当代内生增长理论，本文建立了一个将R＆D和R＆D溢出与资本积累之间、R＆D和R＆D溢出与总产出增长之间直接关联起来的动态模型。面板数据协整检验实证分析结果表明R＆D和R＆D溢出与资本积累之间、R＆D和R＆D溢出与总产出增长之间分别存在显著的正面长期协整关联。进一步的分析表明，R＆D与资本积累之间、R＆D与总产出增长之间分别存在显著的长期双向格兰杰因果关系。由此观知，R＆D乃长期经济增长源泉之所在。另一方面，尽管资本积累或总产出增长并不格兰杰导致R＆D溢出，证据表明R＆D溢出格兰杰导致资本积累和总产出增长。这种由R＆D溢出到资本积累和总产出增长的单向格兰杰因果关系意味着尽管知识与技术的跨国传播并非必然发生。其实为世界经济增长的重要动力。     

Education Subsidies, Social Security and Growth: The Implications of a Demographic Shock

We develop a three-period overlapping-generations model in which individual decisions about education are the engine of growth. In this setting, we investigate the normative role of education subsidies and old age pensions. Calibrating this model on empirical data, it is shown that the case for positive pension benefits is rather weak on the optimal path. An important part of education subsidies should be financed by lump-sum taxes on retirees. We also examine how these transfers should be adjusted in the presence of a baby boom-baby bust demographic shock. It turns out that an appropriate policy could be to increase education when the baby-boom generation is at work. Labor productivity will then be higher when aging peaks so that the pension bill can be financed without reducing welfare for the baby-bust generations.

教育不平等、增长非平衡与低发展陷阱——对农村教育和农村经济协调发展的考察

改革开放以来,我国城乡差距、农村的地区发展差距有所扩大,不公平的教育资源分配导致人力资本的不平等配置,要根本解决经济发展差距问题,达到均衡发展的目的,关键之一是要解决好农村教育的全面协调发展问题。要打破这种不均衡的教育资源配置和低发展的陷阱,必须提出教育扶贫的理念和措施。教育扶贫就是通过提高整个农村特别是落后地区农村居民的受教育水平、职业技能,进而达到促进当地经济发展的目的,这不但是对教育本身有意义,而且由于其对经济社会长期性、根本性的影响,在某种意义上讲甚至比经济扶贫更重要,针对农村教育的现状和特征,必须加大教育扶贫的力度,提高扶贫的效率。     

Growth and social security: the role of human capital

This paper studies the growth and efficiency effects of pay-as-you-go financed social security when human capital is the engine of growth. Employing a variant of the Lucas model [Lucas, R.E., 1988. On the mechanics of economic development. Journal of Monetary Economics 22, 3–42.] with overlapping generations, it is shown that a properly designed, unfunded social security system leads to higher output growth than a fully funded one. Furthermore, the economy with an unfunded social security is efficient, while the other one is not. These results stand in sharp contrast to those obtained in models where the reason for economic growth is physical capital accumulation.

Health Insurance, Liquidity and Growth

Within the context of an endogenous growth model, it is shown that in the presence of health risks which influence household income, the introduction of a private insurance company increases the long-term economic growth rate. The introduction of such an institution has two effects on savings: a level effect and a composition effect. Although the presence of this risk-reducing institution induces a decrease in the level of total savings, as suggested in earlier papers, the rate of illiquid savings, which contribute to growth, increases.
