Changing factor market conditions in South Africa: The capital market – a sectoral description of the period 1970–97

This article explores changing conditions in South African real capital markets. Noteworthy is the evidence of strong restructuring in this market during the 1990s. Whereas the 1970s and 1980s showed the best investment performance among primary commodity sectors and sectors with strong parastatal involvement, the highest investment rates of the 1990s have been associated with the manufacturing industry. We show that the real user cost of capital and capital productitivity contribute plausible determinants of investment rates in South Africa. The extent to which market forces are allowed to bring in line marginal cost and marginal return on capital appears to influence the sustainability of investment.     

Economic subsidies and incentives in education for low-income people

Conclusion First, education is both a private and a public good. We may specify a social welfare function for education as a social good with externalities and internalities, social costs, and social benefits. We may also analyze education as a private good and specify production functions, consumption functions, investment functions, and capital accumulation functions for it. Both micro and macro relations are involved in its production and use. Stock-flow-stock variables are involved in the theory and applications. Economic education is no less important for low income people than it is for the nonpoor and the rich in a conservative capitalistic system.     

Patents,foreign direct investment and economic growth in Australia, 1860–2010

We examine the long run relationship between innovation and economic development in Australia, using 150 years of data on patenting activity, and aggregate and sectoral economic indicators. Our initial results point to several important causal relationships, particularly the effects of patents on real GDP and of private capital formation on patents. We delve deeper at the sector level and find important causal relationships of patents with real foreign direct investment (FDI) since World War II. Australia's dependence on FDI for private capital formation served as an important stimulus for knowledge creation in key sectors including manufacturing, agriculture and mining.     

Public Goods,Tax Policies,and Unemployment in LDCs

We build a general equilibrium model of a small open economy characterized by unemployment and producing two privately traded goods and one nontraded public consumption good. The provision of public good is financed with an income tax or an excise tax on the manufactured good or an import tariff. Within this framework, the paper examines the effects of such policies on the country's unemployment ratio and welfare, and it derives the efficiency rules for public good provision for each policy instrument. It shows, among other things, that the private marginal cost of the public good always overstates its social marginal cost in the case of income taxes and may overstate it in the case of an excise tax on the manufactured good or a tariff even if the taxed good and the public good are substitutes in consumption.     

旧中国信用合作失效的社会资本解释及启示

简要介绍了建国前农村信用合作运动,并从社会资本角度对其失效的原因进行了剖析,在此基础上,认为目前农村合作信用的健康持续发展要注意与政府构建链合性社会资本、要结合当地的社会资本实际情况确定信用合作组织的规模和发展步调。     

基于信任的社会资本与民营企业可持续发展

20世纪90年代以来,社会资本成为企业发展的重要话题。它不但成为解释企业持续发展的理论,也被奉为探求组织发展的有效方法。信任是社会资本的重要内容。信任资源不足是我国民营企业成长的瓶颈。本文通过对我国民营企业中信任型社会资本的现状分析,提出民营企业应加强信任型社会资本的挖掘和建设,以促进我国民营企业可持续成长。     

私人资本主导生产和分配及其财产权问题研究

人的生存和发展被设定为资本收益最大化的条件,是私人资本主导社会生产和社会分配以及二者结合的最大特点,这样必然出现:(1)获得生存和发展保障的只是一个特定的群体;(2)获得的保障有限;(3)要以牺牲部分人生存和发展保障为代价;(4)要以牺牲当代人和未来人生存和发展条件为代价。私人资本占有社会生产成果需要设计特别的财产权。资产阶级经济学的产权理论把剥削和占有的行为掩藏起来,让资本可以通吃其他生产要素的分配权。以私人财产面目掩盖着的私人资本,由于其占有其他生产要素收益权的产权关系不合理地扩展了私人财产本身应有的产权关系,其收益权的保护需要根据实际情况来确定。长期以来,在不合理的经济学理论引导下,社会生产和社会分配以及二者的结合以资本收益最大化为原则,人类社会生产发展以保障人生存和发展为目的被以资本收益最大化为目的取代,社会生产发展的目的和手段出现了不应该出现的倒置。资本家阶级原本只应该为社会生产的发展服务,为保障人的生存和发展服务,而不是要社会生产的发展或人的生存和发展为他们获取资本收益最大化服务。事实上,如果我们始终把资本家阶级看成是与社会生产的发展不可分割的部分,他们就是与社会生产发展过程有机组合起来的一个优秀群体,就如同是在社会生产发展过程中不可或缺的劳动者一样,参与社会生产的目的都是为了保障人的生存和发展。这样的优秀群体中的每一个人,必然、也应该会是真正自由而全面发展的人。     

The increasing returns to scale CES production function and the law of diminishing marginal returns

This article analyzes the constant elasticity of substitution (CES) production function when there are increasing returns to scale and the elasticity of substitution exceeds 1, which I refer to as the explosive case of the CES. For this explosive case of the CES, the article demonstrates a new and surprising result: marginal and average products of labor and capital approach infinity as either labor or capital approach infinity. Obviously, in this explosive case of the CES, the law of diminishing marginal returns is eventually violated in a dramatic way. Some implications of this result for growth theory are discussed. The article concludes by deriving, for this explosive case of the CES, lower and upper bounds for the capital labor ratio which are consistent with the law of diminishing marginal returns.     

Adverse Selection in Private Annuity Markets and the Role of Mandatory Social Annuitization

We study the effects on the macroeconomic equilibrium, the wealth distribution, and welfare of adverse selection in private annuity markets in a closed economy inhabited by overlapping generations of heterogeneous agents who are distinguished by their health status. If an agent’s health type is private information there will be a pooling equilibrium in the private annuity market. We also study the implications for the macro-economy and welfare of a social security system with mandatory contributions that are constant across health types. These social annuities are immune to adverse selection and therefore offer a higher rate of return than private annuities do. However, they have a negative effect on the steady-state capital intensity and welfare. The positive effect of a fair pooled rate of return on a fixed part of savings and a higher return on capital in equilibrium is outweighed by the negative consequences of increased adverse selection in the private annuity market and a lower wage rate.     

Endogenous Comparative Advantages in Developing Economies

This paper focusses on endogenous comparative advantages in developing countries, in particular on labour reallocation from low-productivity informal sectors into high-productivity formal sectors. This mechanism is important for two reasons. First, it contributes to the growth potential of developing countries and the absorption capacity for further capital accumulation. Second, labour reallocation will keep developing economies specialized in low-skilled intensive products in the coming decades and it will keep the wages of low-skilled workers low. We analyse this mechanism by simulating an increase in the skill intensity of developing countries the coming decades. These simulations are carried out with WorldScan, a dynamic AGE model of the world economy. An increasing skill intensity in LDCs will stimulate the global supply of high-skilled intensive products more than the supply of low-skilled intensive products, but to a much lesser extent than one would expect in static analyses or in absence of informal sectors.     

The Effect of the Exchange Rates on Investment in Mexican Manufacturing Industry

This paper, considering revenue and cost exposure channels, investigates the effects of exchange rate on fixed capital investment in Mexican manufacturing sector over 1994–2003. We find that i) currency depreciation has a positive (negative) effect on fixed investment through the export (import) channel; ii) exchange rate volatility impacts mostly export oriented sectors; iii) the sensitivity of investment to exchange rate movements is stronger in non-durable goods sectors and industries with low mark-up ratios.

International Saving, Investment and Trade

Feldstein and Horioka (Econ J 90:314–329, 1980) observed that saving and investment move closely together in the major OECD countries. This finding is a puzzle if national economies are characterized by one sector neoclassical production functions—with diminishing returns to capital, a high level of savings in a country should create an incentive to export capital. In this paper, we show that this incentive disappears in the presence of multiple sectors with differing capital intensities. In a high saving country, national capital can be absorbed domestically without a decline in its marginal product through a shift in the sectoral composition of national production towards capital intensive sectors. This is nothing but the well-known Rybczynski effect. We present a modified version of the standard Heckscher–Ohlin (HO) Model to show that very small barriers to capital mobility are enough to force national savings to stay within the country of origin. We also argue that, while the assumptions of this model may appear special, they are not unrealistic for the developed countries in the Feldstein Horioka study. Some historical economic trends are also consistent with the picture presented in this paper. Finally, the paper shows that the conventional insights from the one sector neoclassical model can be completely overturned in a multi-sector setting when technological differences are introduced.

Estimates of average marginal tax rates on factor incomes in Japan

In this paper, we estimate average marginal tax rates on factor incomes in Japan from 1963 to 2007. We adapt the method of D.H. Joines [Estimates of effective marginal tax rates on factor incomes. J. Bus. 54 (2), 191-226.] to the Japanese tax and social security system. Average marginal tax rates on labor incomes without social security premiums range from 14% to 21%, whereas the rates on incomes with social security have increased from 21% to 33%. Tax rates on capital incomes have fluctuated between 35% and 58%. We also compare our estimates with average tax rates and the wedges from business cycle accounting.     

For goodwill or resources? The rationale behind firms' corporate philanthropy in an environment with high economic policy uncertainty

This paper investigates the impact of economic policy uncertainty (EPU) on the corporate philanthropy (CP) behaviors of firms using a dataset from Chinese A-share listed firms. We find that, on average, firms decrease their CP significantly when economic policy uncertainty increases, but the response is heterogeneous for firms with different ownership types. Compared with their counterparts, private firms are willing to contribute more donations in an environment with high economic policy uncertainty. Further analysis shows that private firms take on more other types of corporate social responsibility at the same time, and private firms' additional CP in a high EPU environment is rewarded with more subsidies, indicating that altruistic and political motives may play important roles in driving the CP behaviors of private firms. There is no evidence that private firms selling products directly to consumers are more likely to engage in additional CP. Our findings indicate that the main motivation behind Chinese private firms' additional CP under high economic policy uncertainty is seeking more government resources, instead of keeping consumers loyal by maintaining good reputations during hard periods.     

Total capital and economic growth

In contrast to the official estimates of gross private domestic investment and associated capital stocks prepared by the Bureau of Economic Analysis (BEA), the author presents estimates of total investment and capital, human and nonhuman, tangible and nontangible, by all sectors of the U.S. economy. Total investment is 3.1 times the BEA estimate in 1929, rising to 4.1 times in 1990. It accounts for almost half of adjusted GDP in the latter year. As hypothesized, real total capital stocks rise at about the same 2.9 percent average annual rate as real gross domestic product 1929–90, 0.1 percentage points more in the total economy and 0.2 points less in the predominant business sector. Increases in nontangible capital (mainly education, training, health, and research and development—“R&D”-) largely explain the growth in total tangible factor (capital) productivity in the whole economy. Nontangible, human capital has grown relatively faster in the business sector than in the entire economy, helping to explain its more rapid productivity advance. The author recommends that when BEA shifts to the U.N. standard system of accounts, it include nontangible and human tangible investments and capital in “satellite” accounts, as well as tangible investments for all sectors in the core accounts. This will greatly facilitate the analysis of economic growth. Presidential Address at the Thirty-Sixth Atlantic Economic Society Conference, October 7–10, 1993, Philadelphia, Pennsylvania.     

The impact of public investment on private investment spending in Latin America: 1980–95

This paper investigates the theoretical and empirical links between key economic variables and private spending in Latin America during 1980 to 1995. The empirical findings of this paper directly address the complementarity hypothesis which suggests that increases in public investment spending raise the marginal productivity of private capital, thereby inducing higher rates of private investment spending. This paper also addresses the issue of whether changes in the real exchange rate (expenditure-switching policies) have a deflationary effect on the economics of Latin America. The findings in this paper make an important contribution to the ongoing debate about which policies need to be promoted to raise and sustain the rate of private capital formation in Latin America—the region's future source of employment and income creation.     

The Relation between Strategy,CEO Selection,and Firm Performance

We examine whether a firm's strategic priorities influence its selection of a new CEO and what conditions enable such an appointment to add value to the firm. More specifically, this study investigates the value‐adding effect when prospector firms (i.e., those pursuing a prospector‐type strategy) select a CEO with high social capital. We argue that uncertainty, driven by a firm's strategy, will determine the decision to select a CEO with high social capital; such CEOs can use their networks to mitigate the uncertainty and thus can be valuable to the firm. However, prior research indicates that CEOs with high social capital can engage in behavior detrimental to firm value. To mitigate the potential for this to occur, we assess whether corporate governance can play a role in prospector firms who appoint CEOs with high social capital. Drawing on archival data of CEO successions over a 14‐year period, we find that prospector firms have greater incentives to appoint CEOs with high social capital. We also find that prospector firms who appoint a CEO with high social capital improve their performance. Furthermore, the value‐adding effect of this selection choice is stronger in prospector firms with good corporate governance.     

ECONOMIC ANALYSIS ON THE URBAN–RURAL DISPARITY IN HUMAN CAPITAL IN CHINA

With China's economic development and capital accumulation in the industrial sectors, the human capital level of the labours moving from the rural areas could no longer meet the demand of the industrial sectors. Therefore, “structural shortage of technical labour” emerged in the labour market as a result of excess of demand for high‐skilled workers. Previous literature mostly focused on the relationship between rural human‐capital level and labour movement, income change and economic growth, but in this article, the authors focus on the study of the relative disparity of urban and rural human capital and labour movement, as well as the effect of the change of urban–rural human capital gap on industrial output, profit and social welfare. This article shows that bridging the urban–rural gap in respect of human capital level could not only improve the situation of the “structural shortage of technical labour,” but also have a positive effect on the general social welfare.
