This paper develops a general equilibrium model with endogenous clusters and an endogenous network of division of labour to formalize and explore the interrelationship and rules of industrial clusters, the network of division of labour, and the economies of specialization and agglomeration in the new era of globalization and regionalization. The model suggests that institutional efficiency and competition among countries and industries will facilitate important circular effects, propelling and shaping the arrangement and allocation of industrial clusters, establishing their position in the value chain, and, consequently, determining the status of economic growth. In particular, the improvements in institutional efficiency of economic and technology systems will expand the demand for transactions and network size, which, in turn, will determine the development of cluster and network scope, as well as the position in the production value chain.  相似文献

In this paper, we develop a general equilibrium endogenous growth model that emphasizes the IPR enforcement effects on growth, in a scenario of north–south technological knowledge diffusion. The economy consists of three sectors, and firms are engaged in step-by-step innovation. In line with the literature, we introduce an IPR parameter that makes imitation more difficult. We find that, in steady state, the increases in IPR protection result in decreases in the growth rate. This result is in line with the literature, which argues that the enforcement of IPR does not always have a positive effect on economic growth. To sum up, we present some suggestions for future research which can help to clarify the relationship between IPR and endogenous growth.  相似文献

We explore the hypothesis that demographic changes which began in the seventeenth and eighteenth centuries are at the root of the acceleration in growth rates at the dawn of the modern age. During this period, life tables for Geneva and Venice show a decline in adult mortality; French marriage registers reveal an important increase in literacy; historians measure an acceleration of economic growth. We develop an endogenous growth model with a realistic survival law in which rising longevity increases individual incentives to invest in education and fosters growth. We quantitatively estimate that the observed improvements in adult mortality account for 70% of the growth acceleration in the pre‐industrial age.  相似文献

This paper contributes to the debate on the relationship between human capital, institutions, and economic growth. The paper first develops a micro-foundation model linking institutions to human capital. The advantage of our modeling strategy is that the human capital accumulation function is derived from an endogenous process. The theoretical model shows that improvements in the quality of institutions foster human capital accumulation, decrease income inequality and change the historical development path. The paper uses cross-country panel data from 1965 to 2005 to test some of the model's propositions and finds that deep structures or structural institutions – which are very persistent and rooted on the historical development path of an economy – affect long-term economic performance, while political institutions are uncorrelated with productivity and long-term economic growth. The empirical estimates also show that growth of physical and human capital – instead of levels – determines long-run economic growth.  相似文献

This study extends a two-sector Kaleckian model of output growth and income distribution by incorporating endogenous labour productivity growth. The model is composed of investment goods and consumption goods production sectors. The impact of a change in wage and profit shares on capacity utilisation and output growth rates at the sectoral and aggregate levels are identified. The study reveals short-run cyclical capacity utilisation rates and productivity growth dynamics. Even if the short-run steady state is stable, the capital accumulation rate in the consumption goods sector must decrease more than that in the investment sector for long-run stability. When simultaneous rises in profit shares in both the sectors affect long-run aggregate economic growth differently at a steady state, the distributional interests between the same class in different sectors may hamper the long-run economic growth. A policy message is that the effect of income distribution on industrial output growth is not always beneficial. These phenomena are specific to two-sector models and cannot be observed when using conventional aggregate growth models.  相似文献

In the present paper, we examine the economic growth effects of a limited availability of higher education in a simple endogenous growth model with overlapping generations. It is shown that this limited availability might promote economic growth by increasing aggregate savings. If the supply of human capital is restricted, its price remains high and a large share of aggregate output is distributed to young households, which need to save for their old age. When this growth‐enhancing effect is strong enough, an excessive increase in availability leads to a shortage of investable funds, which substantially reduces economic growth.  相似文献

Leisure time, savings and trade patterns A two-country growth model   总被引:1,自引:0,他引:1  
This paper proposes a simple two-country endogenous growth model with endogenous consumption, leisure time and wealth accumulation. The model examines possible causes for the world economic growth and the existence and persistence of trade patterns between countries with different preferceces and human capital under internationally free capital mobility. We show how differences in preferences in consumption, leisure time and wealth between the two countries may affect long-run world economic growth.  相似文献

浅析现代经济增长理论的演变   总被引:1,自引:0,他引:1  
经济增长不仅是经济学研究的永恒主题,更是全世界都普遍关注的问题。从亚当·斯密开始,经济学家就不断地对经济增长进行探索。正是由于经济增长与全世界人民的福利息息相关,所以我们对经济增长的研究就显得格外重要。然而随着经济全球化的发展,传统经济增长理论已经不能解释现代社会经济发展过程中出现的种种现象。理论和现实之间的矛盾促使我们探求现代经济增长理论,以更好地解释世界。因此,对现代经济增长理论的演变进行探索,具有积极的理论和现实意义。本文从经济增长的事实入手,首先界定了现代经济增长的概念,然后对现代经济增长理论的发展脉络进行梳理和阐述,分别对哈罗德一多马模型、新古典经济增长模型(外生增长理论)和新增长模型(内生增长理论)进行了详细分析。通过分析可见现代经济增长理论经历了由技术外生增长到内生增长、市场结构由完全竞争到垄断竞争的演变。  相似文献

This paper deals with transition mechanisms through which financial market conditions affect real economic growth in the Euro area. The informational content of financial variables for predicting real economic growth is assessed, allowing for asymmetric responses to shocks. A nonlinear framework is developed based on a smooth transition model for which the effects of shocks can vary across business cycles when financial indicators modify both the endogenous and state variables. Global financial variables are shown to significantly affect real growth in the Euro area, particularly during periods of recession. Changes in stock market index and yield slope have asymmetric effects on real growth. In recessionary periods, the slope of the US yield curve does not have a significant impact on growth in the Euro area.  相似文献

本文将碳减排的约束条件及碳减排成本弹性系数引入生产函数,将人们对气候变化的警惕意识引入效用函数,在内生经济增长模型的研究框架内系统分析了碳减排影响经济增长的内在机制以及实现经济增长和控制碳排放双重目标的条件。研究表明:在低碳基础设施不完善及低碳技术应用不广泛的阶段,加快碳减排将给经济带来较大的负效应;控制碳排放除了与碳减排速率、非化石类能源的增长等客观因素有关外,还与人们应对气候变化的主观意识有关;为实现社会福利最大化条件下的长期经济增长与控制大气中温室气体存量的双重目标,碳减排最终将依靠科技进步以及非化石类能源的增长。  相似文献

More than a third of the EU budget is devoted to Cohesion Policy with the objective to foster economic and social cohesion in the European Union. Large-scale fiscal transfers are used to support investment in infrastructure, R&D and human capital. This paper provides a model-based assessment of the potential macroeconomic impact of these fiscal transfers using a DSGE model with semi-endogenous growth (Jones, 1995) and endogenous human capital accumulation. The simulations show the potential benefits of Structural Funds with significant output gains in the long run due to sizeable productivity improvements.  相似文献

The paper provides a theoretical explanation for the inverted U-shaped relation between pollution and income often found in empirical research (Environmental Kuznets Curve). We model the transition in the pollution pattern as a change in general purpose technologies and investigate how it interferes with economic growth driven by quality improvements. We provide an analytical foundation for the claim that the rise and decline of pollution can be explained by endogenous innovations, policy-induced technology shifts, and intrasectoral changes. Once environmental degradation becomes too severe, regulation is introduced by which society forces the economy to make a transition to cleaner production.  相似文献

A two-sector growth model is presented in which human capital is acquired through learning by doing. It is shown that, for both the competitive situation and the social optimum, endogenous growth cycles may be the outcome. Concerning the economic prerequisite for persistent oscillations we detect a bunching of investment at nearby dates leading economic variables to overshoot the long-run steady state values. This clustering of investment, for its part, may be caused by adjacent complementarity with respect to the stocks or by a sufficiently strong external effect of investment on the marginal product of physical capital or on the opportunity costs of investment.  相似文献

社会保障制度选择是经济协调发展中的重要课题.本文建立了一个考虑存在收入差距的异质性个体的内生增长世代交替模型,综合考察了社会保障制度选择对经济增长和收入再分配的影响.分析表明,现收现付制对稳定状态的经济增长率有负面影响,但其收入再分配功能对提高社会总福利存在正向作用,通过数值模拟发现当收入差距较小时,现收现付制对经济增长的抑制作用较强,随着收入差距的拉大,收入再分配功能将逐渐居于主导地位,其综合效应可以改善社会福利.在一定的收入差异程度范围内,存在一个使社会福利最大化的最优现收现付制比率.基于对中国实际的分析,本文认为我国未来的社会保障制度改革应该注重发挥现收现付制的再分配功能.  相似文献

Recent empirical evidence demonstrates that a higher level of technical progress is associated with a lower level of growth volatility and higher expected economic growth. This paper builds a simple growth model which combines the insights of Angeletos and Kollintzas (2000) and Tse (2000; 2001; 2002) with endogenous productivity growth and rent-seeking behavior to account for these stylized facts. Our model complements the literature that focuses on the heterogeneity of different agents.  相似文献

中国经济增长模型的设定:1952—1998   总被引:59,自引:0,他引:59  
现代经济增长理论能够刻画我国的经济增长吗 ?如果能 ,那么哪类经济增长理论能比较好地刻画我国的经济增长呢 ?围绕这些问题 ,本文从实证和理论两个方面展开讨论。在实证上 ,本文采用Jones( 1 995)实证检验新增长理论的方法 ,针对各类经济增长理论的核心特征 ,实证分析了 1 952— 1 998年间我国经济增长的典型事实 ,结果发现这些典型事实明显地拒绝了新古典增长理论和R&D类型增长理论 ,相对而言 ,比较支持AK类型增长理论。另外 ,我们还发现以综合要素生产率测量的技术进步 ,不是我国1 952—1 998年间经济增长的引擎。在理论上 ,本文从“边干边学”的角度 ,把“探索适合我国国情的经济建设道路”纳入经济增长模型 ,证明了其本身可以作为我国经济增长的引擎 ;同时回答了为什么AK类型增长理论能够刻画我国的经济增长。  相似文献

The central component of most economic models that analyse the transition from the Malthusian regime to self-sustaining developed economies is education. Improved health is normally envisaged as simply a by-product of economic growth. Whereas growth does, indeed, tend to improve health status, the reverse is also true, namely that health improvements are a dynamic force capable of driving economic expansion. This paper underlines the importance of health improvements in escaping from Malthusian stagnation. Further, and in contrast to existing literature, which emphasizes the effects of changes in mortality rates, this paper focuses on the relationship between health status and the efficiency of human capital technology. Through this channel, health improvements stimulate investments in child quality in terms of both nourishing and schooling and drive the economy towards the Modern Growth regime.  相似文献
