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.

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.     

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.     

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.     

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。     

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.     

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.

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.

Does Precommitment Raise Growth? The Dynamics of Growth and Fiscal Policy

We develop an endogenous growth model driven by externalities from both private and public capital. The government levies distortionary taxation to finance a publicly provided consumption good and public infrastructure. Firms face adjustment costs. We compare the optimal and time-consistent policies in a linear-quadratic approximation of the model. Although the time-consistent equilibrium is sub-optimal in terms of ex-ante intertemporal welfare, it yields higher long-run growth and welfare, through an accumulation of assets by the state and a cut in government consumption.     

Growth and the Environment in Europe: A Guide to the Debate

Many articles on the compatibility between growth and environmental preservation provide one single view and use particular concepts. Indeed, debates between advocates and opponents of economic growth are usually unfruitful since people do not talk the same language. The aim of this paper is to provide some clarification in this debate by offering a systematic comparison of perspectives on the basis of a benchmark economic-environmental framework.     

Wealth and the capitalist spirit

The wealth distribution in the U.S. is more unequal than either the income or earnings distribution, a fact current models of saving behavior have difficulty explaining. Using Max Weber’s [Weber, M. (1905). The Protestant Ethic and the Spirit of Capitalism. Charles Scribners’ and Sons (1958 translated edition)] idea that individuals may have a ‘capitalist spirit’, I construct and simulate a model where individuals accumulate wealth for its own sake rather than as deferred consumption. Including capitalist spirit preferences in a simple life cycle model, with no other modifications, generates a skewness of wealth consistent with that observed in the U.S. economy. Furthermore, capitalist spirit preferences provide a way to generate decreasing risk aversion with increases in wealth without resorting to idiosyncratic rates of time preference.     

Endogenous Fertility, Income Distribution, and Growth

This article analyzes the interaction between growth and fertility via income distribution in a model in which fertility decisions are motivated by old-age support. It provides an explanation of the demographic transition of an economy from a stage of increasing fertility and low growth to a stage of low fertility, high human capital investments, and high growth.     

Conspicuous consumption, economic growth, and taxation

Commodities do not only serve the purpose of satisfying direct needs in the production and consumption process. Some of them are also used to display social status and to affect the position of an individual in society. The paper looks at status-seeking activities in an economic-growth context. Two questions are asked. Does status-seeking behavior accelerate economic growth? And: should capital accumulation be subsidized to correct for the status externality? The answers to both questions are ambiguous.     

Relative consumption, economic growth, and taxation

This paper studies the influence of consumption externalities in the Ramsey model. In contrast to the recent literature, a quite general specification of preferences is used and the concept of the effective intertemporal elasticity of substitution is introduced. We give conditions for the observational equivalence between economies with consumption externalities and externality-free economies. An additional key result is that there exist several types of instantaneous utility functions in which the decentralized solution coincides with the socially planned one in spite of the presence of consumption externalities. The conditions for optimal taxation are also derived.     

收入分配、财产分配和渐进改革--纪念《经济社会体制比较》杂志创刊20周年

首先。我想谈一谈收入分配问题。收入分配是整个社会经济系统中一个十分重要的子系统。收入分配的状况不仅影响生产的效率，而且影响人们的切身利益，从而影响社会的协调与稳定。从1988年以来，我和国内外一些同行合作研究中国居民收入分配问题，出版了《中国居民收入分配研究》和《中国居民收入分配再研究》等书。通过系统的实证分析，我认为应该客观全面地看待中国经济改革和经济发展过程中收入分配格局的变化。在这些变化中，有三个问题特别值得重视。     

Human Capital, Growth, and Inequality in Russia

Our model captures the fact that Russia has both much human capital and an education system that produces the wrong skills for a market economy. We define a rule for the timing of educational restructuring that is Pareto optimal and that dominates all later times in a Paretian sense while simultaneously reducing inequality. We demonstrate that failure to implement restructuring early in the transition process is likely to produce a very long delay that will significantly reduce Russia's human capital. A retreat from subsidizing public education is likely to be counterproductive. We argue that early educational restructuring should be emphasized in Russia's transition strategy. J. Comp.
