Income inequality and economic growth—the Kuznets curve revisited

In a neoclassical growth framework with a typical political-economy mechanism, this paper reexamines the relationship between the income inequality and economic growth by introducing government spending into the production function and the utility function. It demonstrates that Kuznets’ famous inverted-U shape relationship between inequality and economic growth will hold—the growth rate will be first increasing with the income inequality before the growth rate decreases with inequality. __________ Translated from The Journal of World Economy (世界经济), 2005,(5) (in Chinese)     

THE TWO‐WAY RELATIONSHIP BETWEEN GOVERNMENT SPENDING AND CORRUPTION AND ITS EFFECTS ON ECONOMIC GROWTH

The existing empirical evidence suggests that in low‐income economies, an increase in government spending leads to a reduction of growth. This article aims to explain this empirical fact by considering a growth model that incorporates a two‐way relationship between corruption and government spending. That is, government spending gives rise to corruption and rent seeking, which feeds back by distorting the structure and size of government spending. In addition, the cost of corruption depends on the wage rate. Therefore, in low‐income economies, increases in government spending tend to generate larger social losses caused by a higher level of rent dissipation and a concomitant rise in corruption and government inefficiency. Consequently, in such economies, an increase in government spending is more likely to result in a decline of economic growth. (JEL H3, O11, O41)     

增长失衡与政府责任——基于社会性支出角度的分析

当前中国的发展出现了以国富与民生关系失衡为本质特征的增长失衡。本文从教育、医疗和社会保障等与民生有关的政府责任切入,指出当前中国与民生状况直接相关的政府社会性支出的不足,是导致增长失衡的重要原因。为此,政府应在提供教育、医疗和社会保障等方面承担起基本的责任,加快财政支出结构转型,增加社会性支出的比重,改善民生状况,纠正增长失衡;并通过社会性支出的增加,促进人力资本积累,推动增长路径的转变,实现经济长期健康发展。     

Democracy comes to Europe: Franchise extension and fiscal outcomes 1830-1938

This paper examines the relation between public spending and the spread of democracy in Western Europe during the period 1830-1938. Our data set includes measures of the size of the electorate, the election rule, and electoral participation, as well as measures of the size and composition of central government expenditures for 12 countries. We estimate panel regressions, and find that (1) the gradual lifting of socio-economic restrictions on the voting franchise contributed to growth in government spending mainly by increasing spending on infrastructure and internal security; (2) the female suffrage had a weak positive effect, through spending on health, education and welfare; (3) the change from majority to proportional rule, which took place in 10 of the countries, did not contribute to growth in government spending, and held back spending on health, education and welfare; (4) there exists (weak) complementarity between economic development and the spread of democracy.     

走向城乡一体化的社会政策体系建设——以“十一五”时期的浙江经验为研究对象

城乡一体化是当代中国社会政策体系建设的基本方向和创新突破口。"十一五"时期,浙江省不断加大社会建设投入、积极创新社会政策、大力提高公共服务能力,初步建立起一个项目比较完备、城乡一体化程度较高的社会政策体系,但仍存在福利性、公平性和体系性的不足。浙江经验表明,推进我国社会政策体系建设向更高水平发展,必须以"城乡一体化"的社会政策创新、民生导向的公共财政体制改革以及优化调整政府间职责分工与财政分配关系为突破口,加快构建基于公民权利的社会政策体系,最终实现社会政策的制度统一并不断提高社会福利水平。     

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.     

SOCIAL STATUS,EDUCATION AND GOVERNMENT SPENDING IN A TWO‐SECTOR MODEL OF ENDOGENOUS GROWTH*

This paper extends the relative wealth specification of status preference to the two‐sector Uzawa (1965 )– Lucas (1988 ) model and examines the effectiveness of government spending on economic growth. It is found that the desire for relative wealth‐induced social status and/or the education component of relative wealth‐induced social status are important ingredients in determining the growth rate effects of government spending. Provided that the agent is concerned with his or her relative social position, the education‐induced social status plays a more important role than the physical‐asset‐induced social status in determining the validity of public spending on growth. If individuals do not care about their education‐driven social rewards, then an increase in government spending has no effect on the balanced growth rate regardless of the presence of the physical‐asset‐induced social status. A rise in government spending reduces the long‐run growth rate if the education‐induced social status is present.     

Interest Groups, Trade Liberalization, and Environmental Standards

In considering a country that imposes a minimum standard on an imported polluting good, which generates negative consumption externalities, we construct a common-agency model, in which a domestic environmental group and a foreign industrial lobby can influence the formation of the minimum standard by providing political contributions to the government. This paper investigates the effects of trade liberalization on the political equilibrium environmental standard, the pattern of trade, environmental disutility, and social welfare. We find that trade liberalization tightens the minimum standard, decreases imports of the polluting good, and reduces environmental disutilities. The importing country’s social welfare, however, does not necessarily increase with trade liberalization. The weaker the environmental group’s lobbying efficiency, or the stronger the foreign firm’s lobbying efficiency, the more likely it is that trade liberalization will enhance the importing country’s welfare.     

政府规模扩张、福利效应与政策矫正*——基于门槛效应模型的经验研究

不同于既有研究关注政府规模扩张的影响因素和经济效率,本文考察了我国政府规模扩张的社会福利效应,有两个重要发现：第一,非线性。本文使用2000-2012年省级面板数据和Hansen TM方法实证发现,2000年以来,我国省级政府规模与财政分权、转移支付、经济增长的交互作用对社会福利具有非线性影响,分别表现出N型、倒U型和N型。第二,地异性。各省份由于财政分权程度、转移支付力度和人均收入水平差异,上述非线性机制和政府规模影响社会福利的门槛效应具有典型的地区差异。在“供给侧结构性改革”背景下,为防范政府规模扩张对社会福利增进由“初始的正效应”转向“最终的负效应”,本文提出了相应的政策矫正建议。     

中国通货膨胀的福利成本研究

Inflation is always an important indicator to measure whether economy is stable and healthy. This paper provides a substantive survey of the research on the welfare cost of inflation, and uses the methods of consumer’s surplus and neo-classical general equilibrium models respectively to estimate the welfare cost of inflation in China. The results show that high inflation will cause huge welfare cost in China, so keeping low inflation is beneficial to the entire economic welfare of China. __________ Translated from Jingji Yanjiu 经济研究 (Economic Research Journal), 2007, (4): 30–42, 159
