R&D、R&D溢出、内生增长和内生收敛   总被引:1,自引:0,他引:1  
根据强调知识与技术创新、知识与技术溢出重要性的当代内生增长理论,本文建立了一个将R&D和R&D溢出与资本积累之间、R&D和R&D溢出与总产出增长之间直接关联起来的动态模型。面板数据协整检验实证分析结果表明R&D和R&D溢出与资本积累之间、R&D和R&D溢出与总产出增长之间分别存在显著的正面长期协整关联。进一步的分析表明,R&D与资本积累之间、R&D与总产出增长之间分别存在显著的长期双向格兰杰因果关系。由此观知,R&D乃长期经济增长源泉之所在。另一方面,尽管资本积累或总产出增长并不格兰杰导致R&D溢出,证据表明R&D溢出格兰杰导致资本积累和总产出增长。这种由R&D溢出到资本积累和总产出增长的单向格兰杰因果关系意味着尽管知识与技术的跨国传播并非必然发生。其实为世界经济增长的重要动力。  相似文献

The current note clarifies that Condorcet Jury Theorem cannot be generalized to the extended setting where individual decisional skills are not assumed to be exogenous parameters even when these skills are homogeneous. This is true when skills are determined endogenously either by a central planner or, in a decentralized strategic setting, by the decision makers themselves.  相似文献

This note applies the approach of Miyagiwa and Papageorgiou [Miyagiwa, K. and Papageorgiou, C., 2007. Endogenous aggregate elasticity of substitution. Journal of Economic Dynamics and Control 31, 2899–2919] to provide simple frameworks for endogenizing the aggregate elasticity of substitution between capital and labor for a growing small open economy.  相似文献

Health Insurance, Liquidity and Growth   总被引:3,自引:0,他引:3  
Within the context of an endogenous growth model, it is shown that in the presence of health risks which influence household income, the introduction of a private insurance company increases the long-term economic growth rate. The introduction of such an institution has two effects on savings: a level effect and a composition effect. Although the presence of this risk-reducing institution induces a decrease in the level of total savings, as suggested in earlier papers, the rate of illiquid savings, which contribute to growth, increases.

A local dynamic analysis, in the neighborhood of the steady state, is developed for one and two-sector endogenous growth models. The problem differs from the conventionally assumed growth setups because one considers that expectations concerning the next period value of the control variable (consumption) are formed through adaptive learning. In such scenario, the found stability conditions reveal that convergence to the unique steady state point is feasible if a minimum requirement regarding the quality of learning in the long run equilibrium is fulfilled. Therefore, stability of growth under learning is dependent on the efficiency with which expectations are generated.  相似文献

We develop a three-period overlapping-generations model in which individual decisions about education are the engine of growth. In this setting, we investigate the normative role of education subsidies and old age pensions. Calibrating this model on empirical data, it is shown that the case for positive pension benefits is rather weak on the optimal path. An important part of education subsidies should be financed by lump-sum taxes on retirees. We also examine how these transfers should be adjusted in the presence of a baby boom-baby bust demographic shock. It turns out that an appropriate policy could be to increase education when the baby-boom generation is at work. Labor productivity will then be higher when aging peaks so that the pension bill can be financed without reducing welfare for the baby-bust generations.

Should government subsidize R&D and does it matter how these subsidies are allocated? We examine these questions in a dynamic model where R&D is described as sequential sampling from a distribution of new ideas. Successful discoveries affect future available resources and incentives for further R&D. Consequently, there may be under-investment in R&D. We study the effect of government interventions aimed at fostering growth through R&D. Calibrating the model with aggregate data from the Israeli business sector allows us to quantitatively compare two forms of support resembling those actually used to encourage R&D in the Israeli business sector: (i) an unrestricted subsidy that may be used at the recipients' discretion to finance R&D or other investments, (ii) a subsidy earmarked by the government for R&D activities only. While there is no theoretical way to determine which of the two subsidies will have a greater impact on search for new ideas and growth, we find that in the calibrated economy both subsidies have a significant but similar impact on the economy's output and TFP growth rates. Accordingly, in the case of the Israeli business sector, the incentives to conduct R&D were sufficiently strong, and no R&D-specific encouragement was needed. However, a sensitivity analysis reveals that for economies characterized by other parameter values this result may not be true. Correspondence to: B. Bental  相似文献

We show that the simple Aghion–Howitt model exhibits oscillatory indeterminacy in the process of creative destruction as firms undertaking new research do not internalize their effect on existing firms. A simple calibration shows that indeterminacy occurs for quite plausible parametrizations of the share of the intermediate good.  相似文献

We examine human capital's contribution to economy-wide technological progress through two channels – imitation and innovation – innovation being more skill-intensive than imitation. We develop a growth model based on the endogenous ability-driven skill acquisition decision of an individual. It is shown that skilled human capital is growth enhancing in the “imitation-innovation” regime and in the “innovation-only” regime whereas unskilled human capital is growth enhancing in the “imitation-only” regime. Steady state exists and, in the long run, the economy converges to the world technology frontier. In the diversified regime, technological progress raises the return to ability and generates an increase in wage inequality between and within groups – consistent with the pattern observed across countries.  相似文献
