Labour market effects of public capital stock: evidence for the Spanish private sector

This paper provides a new rationale for the positive effect of public capital stock on employment and wages. We show that higher levels of public capital reduce wages along the wage equation and enhance employment due to the resulting larger elasticity of labour demand with respect to wages. The estimation of a structural model for the Spanish private sector reveals that this wage channel is empirically relevant. We use the estimated parameters to simulate the recent incidence of the ratio of public to private capital stock on the private sector economic performance. We find (i) sizeable effects on employment, capital stock and gross domestic product, and (ii) that the wage channel is particularly important for employment.     

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.      

Human capital formation and public debt: growth and welfare effects of three different deficit policies

We analyze an endogenous growth model public educational spending. We show that the balanced budget policy and the policy with a slight deficit yield higher growth than a debt policy where public debt grows at the same rate as GDP, unless the government is a creditor. As concerns welfare, it can be demonstrated that a strong deficit policy yields lower welfare than a balanced budget and a slight deficit policy, unless initial debt ratios are low and the intertemporal elasticity of substitution is high. Finally, there may exist an inverted U-shaped relation between welfare and deficit-financed educational spending.     

Is public capital productive in Europe?

This paper addresses the issue of whether and by how much public investment or public capital can increase GDP. In comparison with the literature on the subject, we apply many different methodologies to answer these questions. A vector autoregressive (VAR) model (for France, Italy, Germany, the UK and the USA), a panel composed of 6 European countries (Austria, Belgium, France, Germany, Italy and the Netherlands) and a regional panel (French regions) are estimated. Public investment is shown to be a significant determinant of output; this is also true for public capital but to a lesser extent than public investment with a VAR methodology. The size of the estimated coefficient is also more realistic than those obtained in the literature. This empirical result confirms that the focus of some economists on safeguarding the level of public investment is not misplaced. The debate on the introduction of a ‘golden rule of public finance’ in the European Monetary Union is legitimate in this respect.     

Population and economic growth with human and physical capital investments

We present a two-sector endogenous growth model with human and physical capital accumulation to analyze the long-run relationship between population growth and real per capita income growth. Formal education and investment in physical capital are assumed to be two separate components of human capital production. Along the balanced growth path equilibrium, population change may have a positive, negative, or else neutral effect on economic growth depending on whether physical and human capital are complementary/substitutes for each other in the formation of new human capital and on their degree of complementarity.

Economic growth as a function of human capital,internet and work

The World Bank has suggested the need to enhance Information and Communication Technology skills in all sectors because a 10% increase in internet connectivity was found to boost GDP growth by 1.38%. Simultaneously, the OECD argued that high internet access rates generate a 2% increase in GDP. Because the internet positively affects economic growth, we investigated the relationship between an economically active population, human capital and technology to evaluate these effects in Mexico. A data series from 1991 to 2010 was analysed in three stages according to the least-squares method. A Cobb–Douglas function under the Solow model was considered. Technology and internet access were found to positively affect top-level students and graduate students and thus contribute to the global innovation index.     

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.     

Investment subsidies and redistributive capital income taxation in a neoclassical growth model

How do investment subsidies bear on pure redistribution when coupled with capital income taxes? In a heterogeneous agent, neoclassical growth framework it is found that on impact, with no optimizing behavior, investment subsidies are good for growth but bad for redistribution. The opposite holds for capital income taxes. But when the government acts as a Stackelberg leader vis-à-vis the private sector (the follower), the optimal feedback policy is by construction time-consistent and implies that in a long-run optimum the tax scheme does not distort accumulation. This holds regardless of social preferences. For the feedback Stackelberg equilibrium I find that (pure) redistribution can go either way and capital income taxes are nonzero in the long-run, time-consistent optimum, depending on the social weight of those who receive redistributive transfers, the distribution of pretax factor incomes, and the intertemporal elasticity of substitution. It is argued that investment subsidies may be an important indirect tool for redistribution, and may allow for the separation of “efficiency” and “equity” concerns.

经济增长模型中的公共资本*

关于公共资本与经济增长关系的理论研究在近二十年来取得了长足进步。本文提供了一个一般性分析框架,将公共资本与经济增长领域的众多研究成果统一在该框架中进行了系统梳理,从而清晰呈现了其理论发展脉络。首先,本文在基本模型中探究了该领域内学者普遍关心的核心问题,这些问题包括增长率最大化与社会福利最大化公共投资规则以及最优与均衡转移路径等。然后,通过逐个放宽基本模型的假设,本文考察了主要结论在扩展模型中是否依然成立。具体而言,本文分别在公共资本具有拥挤性而非纯公共产品性质,公共资本折旧率内生决定而非外生给定,公共投资同时以流量与存量形式而非仅以存量形式影响私人生产以及存在多级政府而非仅一级政府的假设下,对模型结论进行了检验。本文探讨了这些更反映现实的假定对结论产生的不同影响,并进而指出该领域所面临的挑战与未来可能的发展方向。     

Creative capital,information and communication technologies,and economic growth in smart cities

ABSTRACT

We study aspects of economic growth in a stylized smart city with two distinct features. First, the modeled inhabitants of this city are smart because they possess skills. Using the language of Richard Florida, these inhabitants comprise the city’s creative class and hence they possess creative capital. Second, the city is smart because it uses information and communication technologies (ICTs) and we model one specific kind of ICT use. In this setting, we first derive expressions for three growth related metrics. Second, we use these metrics to show that the economy of smart city A converges to a balanced growth path (BGP). Third, we compute the growth rate of output per effective creative capital unit on this BGP. Fourth, we study how heterogeneity in initial conditions affects outcomes on the BGP by introducing a second smart city B into the analysis. At time t?=?0 two key savings rates in city A are twice as large as in city B. We compute the ratio of the BGP value of income per effective creative capital unit in city A to its value in city B. Finally, we compute the ratio of the BGP value of skills per effective creative capital unit in city A to its value in city B.     

The nexus among foreign investment,domestic capital and economic growth: Empirical evidence from the MENA region

The objective of this paper is to estimate an econometric model for analyzing the interrelationship among foreign direct investment, domestic capital and economic growth in 13 MENA countries by using a ‘growth model’ framework and simultaneous-equation models estimated by the generalized method of moments (GMM) during the period 1990–2010. Our empirical results show that there is bi-directional causal relationship between foreign investment and economic growth, as well as domestic capital and economic growth, and there is uni-directional causal relationship from foreign direct investment to domestic capital for the region as a whole.     

Spatial income and public capital: a case of a Spanish region

The objective of this paper is to analyse major determinants of disposable per capita income at a local municipality level for a territory of Spain: the Valencian region. A cross-sectional spatial study for an averaged period (2010–2013) will allow us to control for intraregional correlation, paying special attention to the role of real public investment and its possible effects on disposable personal income. A reference framework for economic and social policymakers will be provided by the specification of the model.     

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.     

FDI, domestic capital and economic growth: Evidence from panel data at China’s provincial level

Based on panel data at the provincial level in China, this paper found that direct effects foreign direct investment (FDI) had on economic growth were of insignificance. However, through improving technical efficiency and “crowding” in domestic investment, FDI produced positive effects on China’s economy. The state sector still played a major part in the total fixed investment, therefore, direct effects on growth were significant. Although private sector was increasingly important for the whole economy, it had no direct influences on economic growth. Meanwhile, neither the state sector nor private sector made contribution to the improvement on technical efficiency. __________ Translated from Shijie Jingji Wenhui 世界经济文汇 (World Economic Papers), 2006, (4): 27–43     

The relation between capital formation and economic growth: evidence from sub-Saharan African countries

This paper examines the causal relationship between capital formation and economic growth in Sub-Saharan African countries using recent panel cointegration and causality testing techniques. We find that causality is bi-directional, suggesting that higher economic growth leads to higher capital formation and that in turn, increases in capital formation results in higher economic growth. These results hold irrespective of whether capital formation is measured with private fixed capital formation or by gross capital formation.

Public capital, endogenous growth, and endogenous fluctuations

Cazzavillan [Cazzavillan, G., 1996. Public spending, endogenous growth, and endogenous fluctuations. Journal of Economic Theory 71, 394–415] studies a discrete-time, one-sector endogenous growth model with a flow of publicly enjoyable goods and productive services financed through income taxation. He demonstrates how equilibrium paths are indeterminate, for a large range of the consumption externality of public spending. This study extends [Cazzavillan, 1996] by considering an otherwise identical production function, except with public capital stock as an input. The results support the robustness of multiple growth paths even in a one-sector growth model with public capital stock, and modify the set of the consumption externality of public spending, in determining growth dynamics in a similar model with non-accumulated public spending.     

Economic development, growth of human capital, and the dynamics of the wage structure

In this paper I elucidate the sources of growth of human capital in the course of economic development. On the supply side (Section 1) I include the growth of family income, urbanization, the demographic transition, and the rising cost of time.The supply side alone cannot explain the continuous growth of human capital as it implies a self limiting decline in rates of return below those in alternative investments. Such declines are offset by growing demands for human capital in the labor market. Growth of demand for labor skills is a function of capital accumulation and of technological changes. Evidence on this hypothesis is summarized in Section 2 and on supply responses to growing demand for human capital in Section 3. Changes in the skill and wage structures in the labor market are an important part of the evidence.The reciprocal relation between economic growth and the growth of human capital is likely to be an important key to sustained economic growth. A caveat applies to indirect effects of economic growth on family instability, which may lead to a deterioration of childhood human capital in some sectors of society.     

关于公共支出与经济增长的国内外研究综述

公共支出与经济增长的关系一直以来为经济学家们所争论。持公共支出促进经济增长观点认为,政府公共支出在经济增长中发挥着重要作用,因为它为经济发展提供了大量的公共品和其他具有外部效应的公共福利或服务,从而鼓励和便利了私人投资,形成了一个较好的投资环境,促进了经济增长。而持反对意见的认为,公共支出往往是生产率较低的,为融通政府支出而形成的高税收又会对私人部门的消费和投资造成很大的负面影响,因此,必须缩减政府支出,才能保证经济增长。当然也有人持两者根本就没有关系的观点。
