Market and public provision in the presence of human capital externalities

For many goods and services, such as health, education, legal services, police protection, the cost incurred by an individual supplier for providing quality is affected by the human capital of her colleagues. The paper shows that this human capital externality is crucial to determine whether such goods and services should be privately or publicly provided. Public and private provisions give individuals different incentives to acquire human capital, and the paper shows that either may be socially preferable, depending on the nature of the human capital externality: private provision of the final goods and services gives stronger incentives to human capital acquisition (and may therefore be socially preferable) if own human capital and one's colleagues' human capital are substitutes, and if suppliers with high human capital benefit more than suppliers with low human capital from their colleagues' human capital, but not excessively so.     

论人力资本产权收益

本文从财务角度对人力资本产权收益的实现机制进行研究.从财务角度来看,人力资本是有意识投资的,具有促进财富和经济增长的内在特性的,一种能享有资本产权收益的价值.所有员工都符合人力资本的特性,因此都是企业人力资本的栽体.按层次可将人力资本分为高层、中层、基层人力资本.人力资本产权特性具有债权和股权双重特性,不同层次人力资本在双重特性上的分布程度是不同的.人力资本产权收益的构成既包括债权投资意义上的收益,也包括股权投资意义上的收益.相对于非人力资本享受的税后收益,人力资本的税后收益的意义更为广泛,还包括剩余控制权相对应的收益.文章提出构建以契约底薪和法定保险为基础,以税后收益分配为调节,同时实施人力资本产权基金制度的人力资本产权收益的实现模式.     

The role of human and social capital in growth: extending our understanding

Human capital, institutions and social capital are now all recognisedas significant factors of growth. They have largely been studiedseparately, and although they present sufficient common characteristicsto be conceptualised as one main category distinct from physicalcapital, it may still be more important to focus on the linksbetween their specific sub-categories. Direct links with incomemay be spurious, as there appears to be a ‘web of associations’between the sub-categories, which would benefit from furtherempirical investigation. This paper reviews the literature onhuman capital, institutions and social capital, extracting threesub-categories of human capital (human skills capital, stock-of-knowledgeand entrepreneurship) and two of social capital (low- and high-rationalisation).Specific areas are then suggested for further empirical study.     

Optimal income taxation in models with endogenous fertility

This paper studies the efficient taxation of factor income in infinite-lived models with elastic fertility choices. Two models are considered, one with physical capital only, and one with physical and human capital. In the model with physical capital only, capital income should be subsidized, while labor income taxed. In the model with two types of capital, instead, Ramsey optimality prescribes that the tax on physical capital is zero (negative), if effective labor is constant (decreasing) returns to scale in human capital and market goods, while the tax on human capital is negative and the tax on effective labor positive. Our findings depart from those obtained in immortal models with an endogenous labor supply and constant population growth, because physical and human capital affect the demand for fertility.

法定公司资本制初始理念的局限性

法定公司资本制是我国现行所采用的资本规范制度,目前,对于这一制度在当下的局限性,众多研究大多集中于探讨其具体制度规则群在现实操作上的困难。然而这样的研究视角尚无法揭示法定资本制与现实的本质悖反,本文力图从法定资本制的初始理念入手,论证法定资本制的两个支撑性初始理念：有限责任外部性问题的规制和公司以资本为信的立法初衷已经与当下的资本运行呈现出一种疏离和悖反之势,从而在更加纵深的层次证明既有法定资本制的根本局限,进一步拓宽这一问题的研究视角,增强改革既有法定资本制这一学术主张的理论说服力。     

ENDOGENOUS ECONOMIC POLICY AND THE STRUCTURE OF PRODUCTION: THEORY AND EVIDENCE

This paper develops and tests a model that predicts a positive relationship between absolute levels of capital stock and how favourable are policies toward capital. The theoretical model we use is a model of campaign contributions and electoral competition, extended to consider the implications for factor mobility and hence the structure of production. There are two main predictions. First, countries with more capital stock tend to implement more pro‐capital policies. Second, in a two‐country model, the country that initially has more capital will be able to attract capital inflows from the other country. Given additional assumptions on the production side, this yields the prediction that the more different are countries' policies, the more different will be the set of goods that they produce. These predictions of the model are confirmed using panel data on cross‐state differences in policies and economic outcomes in India.     

社会资本:融入企业经济学分析框架的思考

社会资本作为第三种资本形式要融入企业经济学的分析框架,不仅应给出它的确切含义,还应区别它与人力资本及其组织资本之间的关系,而且更为重要的是应解决它从哪里分析、在那里运行的问题。笔者认为,企业的本质是团队生产,企业的团队生产不仅放大了对物质资本的利用,形成和累积了团队成员的个人型人力资本,而且还创造出了不能分解到个人身上的团队型人力资本。组织资本与个人型人力资本相关,社会资本则与团队型人力资本相联系。它们的相互作用共同构成了企业的团队生产方式及其效率来源。     

Public and private capital productivity in Russia: a non-parametric investigation

The productivity of public capital has been very popular research topic for US and other OECD countries, while studies using data from transitional countries are almost non-existent. In this paper, we analyze the productivity of public and private capital in Russia with parametric and non-parametric regression methods utilizing a unique regional level panel data from 2003 to 2007. More specifically, we assess public capital’s spillover effects, i.e., the productivity of public capital on private output, as well as the productivity of different capital ownership types on total output. We find that public capital has a clear positive effect on private output. However, our estimates and test statistics show that parametric methods are not able to grasp vast non-linearities and heterogeneity present among Russian regions, while the non-parametric approach can capture these important features of the data better. Furthermore, we find that multicollinearity is an important methodological problem which should be accounted for in analysis concerning capital data. Our results also suggest that the impact of public capital in Russia is heterogeneous in the sense that for some regions its contribution to private output is insignificant or even negative while it has a considerable positive role for most regions. Concerning the capital elasticities of total output, we find that public capital is less productive than private capital and roughly as productive as joint private-public capital.     

A Note on the Taxation of International Capital Income Flows

Seemingly persuasive arguments can be made to suggest that income from foreign-owned capital should be taxed by a small open economy and that it should not be taxed I show that the case for taxing foreign capital income as part of an 'optimal' tax scheme rests on the assumption that tax rates on other forms of income are not set optimally. In particular, if economic profit is not fully taxed, a tax on foreign capital income is desirable. If all tax rates are set optimally, foreign capital income should not be taxed by the capital-importing country.     

Patent protection, capital accumulation, and economic growth

In this paper, we investigate how strengthening patent protection affects economic growth in an endogenous growth model where both innovation and capital accumulation are the driving forces of economic growth. In this model, stronger patent protection raises the profit flow obtained by innovation but reduces the factor demand for capital. This process accelerates innovation but discourages capital accumulation, and because of the negative effect on economic growth through reducing capital accumulation, strengthening patent protection may then impede economic growth. This result contrasts with earlier studies where innovation is the sole driving force for economic growth. Moreover, in an open economy model where technologies are transferred and capital is imported from abroad, the strictest protection of patents enhances technology adoption from abroad but impedes capital accumulation, and thus, the relation derived between patent protection and output can be nonmonotone. In terms of implications, these findings may be able to partly explain the complex relation found by some empirical studies in this area.     

Standard Tax Competition and Increasing Returns

The "race to the bottom" result of the standard tax competition literature implies that capital taxes are competed downward as capital becomes more mobile. The new economic geography literature, in contrast, finds that increasing capital mobility can be associated with a rise in capital tax rates, or a "race to the top." This paper derives the race to the top result from within the standard tax competition modeling framework augmented with agglomeration forces. When agglomeration forces are sufficiently strong, tax competition pressures are mitigated and capital taxes are instead driven by tax exporting incentives.     

CAPITAL AGGREGATION IN THE PRESENCE OF OBSOLESCENCE-INDUCING TECHNICAL CHANGE

The major question addressed is the treatment of capital embodied technical progress. Should Obsolescence be deducted to calculate a net stock, or should quality adjustments be made in each vintage of new capital, or both, or neither? In order to estimate the contribution of new investment to growth it is necessary to use a capital stock where different vintages are weighted in proportion to their marginal products. The commonly used gross capital measures do not do this, because they do not allow for the higher marginal product of more modern capital. Such an allowance for capital embodied technical progress can be made either by quality adjusting new capital or by incorporating obsolescence into the valuation of the old capital (but not both). However, even if new capital incorporates an allowance for improved quality, it will still be necessary to revalue the old capital. Frequently, a reasonable approximation to the net capital stock results from a linear decline in quasi-rents and can be approximated by published estimates of the stock of capital net of straight line depreciation. Steady technical progress will not lead to the commonly used exponential service decline functions. To avoid overestimating the return to investment when technology changes it will be necessary to use information on capital embodied technical change to revalue old capital, rather than to change the price indices for new capital.     

The domestic content of imports and the foreign content of exports

When a country imports goods that have been assembled abroad, some amount of the labor and capital services embodied in those goods may originally be from the country that is now importing them. Similarly, some of the value added of a country's exports may be foreign in origin. For the median country in my sample of 14, I calculate that 21.5% of imported labor services are domestic labor, 17.7% of imported capital services are domestic capital, 12.3% of exported labor services are foreign labor, and 23.3% of exported capital services are foreign capital.     

Investments into education—Doing as the parents did

Empirical evidence suggests that parents with higher levels of education generally attach a higher importance to the education of their children. This implies an intergenerational chain transmitting the attitude towards the formation of human capital from one generation to the next. We incorporate this intergenerational chain into an OLG-model with endogenous human capital formation. In absence of any state intervention such an economy might be characterized by multiple steady states with low or high human capital levels. There are also steady states where the population is permanently divided into different groups with differing human capital and welfare levels. Compulsory schooling is needed to overcome steady states with low human capital and welfare levels. Tax financed education subsidies can lead to further pareto-improvements.     

我国人力资本参与企业收益分配的制度分析

本文认为静态地、抽象地分析企业中人力资本所有权和物质资本所有权谁占支配地位抑或平等是没有意义的。在企业中，人力资本个人收益与企业的总体收益有不同的取向，而非简单地转换。人力资本需要“自己给自己定价”，即靠自身的才干、贡献大小通过有效的机制确定自己从企业收益和剩余收益中分割的多少。因此，设计能够释放人力资本能动性的产权制度和企业治理结构，是中国企业缩小与国外的劳动生产率差距、提高竞争力、加快创新的必然要求。     

Optimal endowments of transport investment: an empirical analysis for mauritius

We investigated the issue of optimality of the provision of transport capital in economic progress. Using an optimization growth model, a condition allowing the assessment of whether public capital would be under- or overprovided was theoretically derived. By deriving a growth equation from a simple production function, we empirically tested this condition for the case of Mauritius during the period 1950–2005. Transport capital is observed to have played an important role in explaining growth of the country. Same is reported for nontransport capital. Interestingly, the null hypothesis that the coefficients of all the types of capital are equal could be rejected, and the estimated coefficient on transport investment proved to be higher than that on private investment (and the nontransport capital). This suggests that transport capital would still be underprovided for the Mauritian case, despite government investment.     

上市公司大股东控制下的资本配置行为研究——基于控制权收益视角的实证分析

基于控制权收益①驱动公司资本配置行为的理论阐释,结合我国上市公司特有的股权结构及其导致的控制权分配格局,文章从固定资产投资和股权投资两个方面,对形成我国上市公司控制权收益的资本配置行为进行了实证研究。研究结果表明:(1)控制权收益水平与资本配置规模显著正相关;(2)控制权收益水平越高,则增加等量控制权收益所需的资本配置规模就越大;(3)较固定资产投资而言,通过股权并购方式取得控制权收益的代价较低,但控制性股东占有被并购公司控制权收益的比例也较低;(4)上市公司资本配置行为在形成控制权收益的同时并没有通过提高公司业绩而增加控制权的共享收益,资本配置决策在很大程度上是大股东控制下的自利行为。
