Culture and human capital in a two-sector endogenous growth model

Recent literature in the field of cultural economics highlights a possible inversion in the usual causality relation (from economic growth to culture) and points out that culture may represent an important driver of economic growth. By viewing culture in line with Throsby’s (2001) definition of cultural capital (i.e., an asset of tangible and intangible cultural expressions), in this article we analyze one possible channel through which culture may positively affect economic growth, namely the existence of a relationship of complementarity between cultural and human capital investments. Using a two-sector endogenous growth model, we find that in the long run a higher growth rate of real per-capita income can be attained the more cultural and human capital investments are complementary for each other in the process leading to agents’ skill acquisition. We also analyze the conditions under which an increase of the cultural capital share in total GDP can be conducive to a rise of real per-capita income.     

Linking technology innovation strategy,intellectual capital and technology innovation performance in manufacturing SMEs

The research interest on Intellectual Capital (IC) has been increasing, adopting different definitions and developing diverse measurement tools. Nonetheless, little research focuses on small and medium-sized enterprises (SMEs) and the relation between IC and innovation management. The purpose of this paper is to investigate the role of technology innovation strategy on the IC development and then on innovation performance in manufacturing SMEs. After conducting a survey, measures of IC for SMEs have been performed and an integrated structural equation model has been created. Results demonstrate that technology innovation strategy affects all IC components, the internal structural capital supports the relational and human capital, and the latter two influence firm technology innovation performance. This study contributes to developing an IC measurement system in SMEs and to emphasise the importance of single IC components in improving technology innovation performance.     

国际技术转移与我国技术创新

在经济全球化、一体化的背景下,跨国公司作为国际技术转移主体的作用正在不断增强,FDI的流入的确推动了我国的经济进步,但跨国公司为了维持其在某些领域的垄断地位,还会千方百计地阻挠这种技术的转移和扩散,加上我国自身的经济结构和体制的障碍及吸收学习能力的有限,技术转移的效应可能达不到理想的理论水平.因此,既要注重跨国公司的技术转移,又不能忽视我国的技术创新,这是实现经济可持续增长的根本所在.     

Optimal fiscal policy in an endogenous growth model with public capital: a note

This note presents an investigation of the optimal tax rule in endogenous growth models with public capital. It is presumed that the government levies only an income tax in addition to financing public investment. Furthermore, a household’s saving is deducted from the income tax. We find the optimal tax rule whereby the social optimum is attainable. The manner by which a government imposes a tax on income and administers tax deductions is important for attaining a socially optimal situation.      

Foreign enclaves and economic development: A theoretical analysis

We consider an urban foreign enclave with sector-specific foreign capital in an otherwise mobile-capital Harris-Todaro model. We consider the taxation of foreign capital. A dynamic version of this model is considered. The long-run equilibrium and the comparative steady-state effects are analyzed. We get some interesting effects of reduction in tax rate on foreign capital on the short-run and the long-run equilibrium levels of domestic factor income and national income under some meaningful conditions.     

Global indeterminacy in an endogenous-growth model with public capital

This paper studies the patterns of growth in an endogenous-growth model where the labor supply is endogenous and sustained growth arises because the services derived from public capital increase the economic productivity. It is assumed that these services are congested by the number of households in the economy but they are not congested by the units of time that each household devotes to work. With this assumption, the dynamic equilibrium exhibits multiple balanced-growth paths, local and global indeterminacy, and limit cycles under some plausible fiscal policies. Our analysis points out that a large lump-sum tax is a necessary condition to obtain this complex equilibrium dynamic behavior.     

企业技术能力与外资对华技术转移的关联研究

将企业技术能力细化为识别技术、选择技术、获取技术、利用技术和保护技术等五个具体能力和一个核心的技术库，五个能力会对外资对华技术转移产生正面和负面影响。外资对中国企业技术能力的提升主要体现在获取技术环节，外资对核心知识的封锁是市场竞争的必然选择，对于技术库的知识累积，只能依靠企业自身的努力。     

国外就业政策及对我国的启示

就业不仅是一个经济问题,还是一个政治问题、社会问题。尽管各国具体国情不同,但在解决失业问题上各国采取了很多相似的政策。应在对各国政策对比的基础上找出共性。笔者认为,我国解决失业问题时,应采取扩大就业总量、提高劳动者素质、加快劳动力市场建设等多方面措施。     

International migration,economic policy and human capital accumulation: a simulation study

"This paper examines the economic policy implications of international migration and human capital accumulation within a dynamic general equilibrium model. Each country produces by means of physical and human capital of two types (skilled and unskilled labour). Along optimal growth paths in a world of diverging population growth rates immigration can only be beneficial when the free rider effect (i.e., not paying for training costs) exceeds the capital dilution effect of an increase in population growth. Under quite general conditions the optimal immigration rate is zero."     

基于索洛模型的外资对中国经济增长的技术贡献率测算研究

外资的引入对于弥补经济建设国内资金短缺,提升产业结构,增加就业和促进进出口等起到了重要的作用,但是其对我国经济增长的技术贡献率却十分有限。借助于索洛余值模型,对于外资在我国经济增长的技术贡献率进行测算研究,分析得出同现实一致的结论。因此,我国要进一步推动利用外资从量到质的根本转变,使利用外资的重点从弥补资金、外汇不足转到引进先进技术、管理经验和高素质人才上来,全面提高引资的技术水平。     

Proof of global stability,transitional dynamics,and international capital flows in a two-country model of innovation and growth

Global stability properties of dynamic two-country models can be easily studied in the case of perfect international capital flows. With internationally constant relative productivities, balanced-growth path values for factor prices will hold on any path leading to the balanced-growth path unless one country experiences a period of no innovation. Innovation rates converge in the case of perfect international knowledge spillovers but long-run consumption levels and trade patterns are path-dependent. GDP per capita is predicted to converge slowly despite the presence of perfect international capital markets and no explicit inclusion of adjustment costs. The trade balance of the rich country is initially positive but after some time turns into a deficit.     

Aggregate returns to social capital: Estimates based on the augmented augmented-Solow model

We extend the augmented-Solow model to estimate the aggregate output elasticity and depreciation rate of social capital that characterize aggregate returns. The estimated output elasticity is approximately 0.1. While social capital positively affects economic growth, the magnitude is much smaller than that of other production inputs. The estimated depreciation rate is at least 10% per annum, which is higher than that of physical capital. The median value of the implied aggregate return of social capital is approximately 19.11% at the global level. In OECD countries, it is likely to be considerably smaller than the individual returns, suggesting the fallacy of composition. While there is no systematic relationship between GDP per capita and returns to physical or human capital, the aggregate returns to social capital seem to be negatively related to the level of development.     

Human capital, inequality, endogenous growth and educational subsidy: A theoretical analysis

This paper develops an endogenous growth model with dualism in human capital accumulation of two types of individuals. The government imposes a proportional income tax on rich individuals and uses the tax revenue to finance the educational subsidy given to poor individuals. We find out the properties of the optimal tax financed educational subsidy policy in the semi-stationary equilibrium of the model using the technique of Stackelberg differential game.     

市场竞争与外商直接投资技术转移--来自中国制造业的证据

目前对技术溢出的研究较少关注"溢出源",尤其是基于市场竞争视角和中国背景的经验研究.文章首先讨论了Wang-Blomstrom假说,进而借助"市场结构-技术创新"关系的研究成果提出"市场竞争-外资技术引进"关系的有关假说,并探讨了异于常规的、面向外资企业的"竞争"的定义和度量,最后基于中国制造业面板数据进行实证检验.实证检验结果表明,外资企业在东道国市场面临更大竞争会促进其增加技术引进,对于发展中东道国,需要具有一定规模和优势的企业而不是接近完全竞争的市场结构,才能提高外资企业面临的竞争程度.     

Trade and technology transfer in a vertically differentiated industry

This paper provides a model of trade and technology transfer in a vertically differentiated industry. We provide three key results. First, freer trade allows an increase in the size of the import competing sector, a counterintuitive proposition. Second, under reasonable conditions a foreign monopolist producing a relatively higher quality product will transfer technology to the local producer for producing a relatively lower quality product. Third, government can design subsidies to induce technology transfer and improve welfare.      

Human capital distribution, growth and convergence

This paper studies the dynamic relationship between distribution and endogenous growth in an overlapping generations model with accumulation of human and physical capital. It is shown how human capital can determine a relationship between per capita growth rates and inequality in the distribution of income. Family background effects and spillovers in the transmission of human capital generate dynamics in which aggregate variables depend not only on the stock, but also on the distribution of human capital. The evolution of this distribution over time is then characterized under different assumptions on private returns and the form of the externality in the technology for human capital. Conditions for existence, uniqueness and stability of a constant growth equilibrium with a stationary distribution are derived. Increasing returns, idiosyncratic abilities and the possibility of poverty traps are explicitely characterized in a closed form solution of the equilibrium dynamics, showing the role played by technology and preferences parameters.     

Entry and technology transfer in a Cournot model

This work studies entry and technology transfer in a Cournot model where there are two domestic firms. A foreign firm has a patent on a technological innovation that reduces the costs of all firms. The foreign firm can license the innovation to one or both domestic firms. The authors consider two standard licensing policies： （1） auction policy and （2） unit royalty policy. The foreign firm can license the innovation either by staying outside the domestic market, or it can enter the market, license the innovation and compete with the domestic firms. The authors show that （1） when the foreign firm stays outside, it is never optimal for it to use royalties, （2） if it licenses the innovation by entering the industry, then royalties could be optimal and （3） when it decides on its entry strategy by taking its optimal licensing policies into account, it always finds it optimal to enter the domestic market.     

Financing technology transfer: assessment of university-oriented proof-of-concept programmes

This study analyses the characteristics of the proof-of-concept (POC) programmes initiated by university and public research organisations in Europe, as a mechanism to address funding gaps and improve the transfer of research-based inventions to markets. We contribute to the literature on investment readiness of new ventures and on financing technology transfer by assessing the structure of such funding instruments and identifying critical success factors for their design and implementation. The analyses rely on seven in-depth case studies of university-oriented POCs in Europe.     

A two-sector overlapping generations model with heterogeneous capital

Summary. This paper characterizes the existence and stability properties of steady state solutions as well as the nature of transition paths of a two-sector growth model with heterogeneous capital. It compares the properties of a Cobb-Douglas–Leontief economy with heterogeneous capital with the properties of the same economy with homogeneous capital. The model with heterogeneous capital reveals a set of characteristics different to those of the model with homogeneous capital. These include the saddle-path stability of the non-trivial steady state as well as the possibility of overshooting and in contrast to the homogeneous capital case, the possibility of damped oscillations along the transition path for realistic parameter values.
