Comment on “The endogenous aggregate elasticity of substitution for a small open economy”

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.     

Money and growth in a cash-in-advance economy with costly credit

This paper develops a stochastic growth model with a cash-in-advance constraint, costly credit, and intermediary services. We study how the behavior of financial intermediaries affects the relationship between economic growth and the monetary system. We show that the payment that intermediaries charge for providing financial services influences the money–growth relationship. When the intermediation cost increases proportionally with credit purchases, we do not observe any influence of growth on the monetary system. When the intermediation cost is not proportional to credit purchases, growth is responsible for a transformation of the monetary system, i.e. money is relatively driven out of the economy as the economy grows.     

Does trade foster contract enforcement?

Contract enforcement is probabilistic, but the probability depends on rules and processes. A stimulus to trade may induce traders to alter rules or processes to improve enforcement. In the model of this paper, such a positive knock-on effect occurs when the elasticity of supply of traders is sufficiently high. Negative knock-on is possible when the elasticity is low. Enforcement strategies in competing markets are complements (substitutes) if the supply of traders is sufficiently elastic (inelastic). The model provides a useful structure of endogenous enforcement that gives promise of explaining patterns of institutional development.

An earlier version of this paper under another title was presented to the American Economic Association meetings, January 2004.     

How to promote R&D-based growth? Public education expenditure on scientists and engineers versus R&D subsidies

This paper compares the positive and normative implications of two alternative measures to promote R&D-based growth: R&D subsidies to firms and publicly provided education targeted to the development of science and engineering (S&E) skills. The model accounts for the specificity of S&E skills, where individuals with heterogeneous ability choose their type of education. Although intertemporal knowledge spillovers are the only R&D externality, the analysis suggests that R&D subsidies may be detrimental to both productivity growth and welfare. Moreover, they raise earnings inequality. In contrast to R&D subsidies, publicly provided education targeted to S&E skills are found to be unambiguously growth-promoting and neutral with respect to the earnings distribution.     

产业集群内生性集体行动影响因素案例研究与效度检验

基于利益集团等多重主流理论视角和半开放性编码技术的部分探索性案例研究,发现产业集群内生性集体行动受到内生需求、长期导向、本地嵌入、政策激励、同行反应、协会治理、集群规模和集群类型等因素的综合影响。经因子分析和逐步回归等方法检验,上述影响因素组合具有较为理想的建构效度和效标效度。其中,内生需求、长期导向、本地嵌入、政策激励、同行反应和协会治理等属于正面激发因素,对集群企业参与内生性集体行动具有积极促进作用,而集群规模和集群类型等则属于负面阻碍因素,对集群企业参与内生性集体行动具有消极抑制作用。     

国有产权安排和国有经济规模内生性研究

运用马克思经济学关于生产力决定生产关系的基本理论和杨小凯发展的斯密-科斯框架的交易费用理论分析所有权安排的演进的内生性决定因素,得出其结论:一种所有权安排是技术变迁和制度变迁相互作用的结果。用内生交易费用和外生交易费用分别来刻画一个特定时点上制度条件和技术条件的现实状况,说明一个时期的内生交易费用和外生交易费用的分布可以决定这个时期的所有权安排。     

金融创新是促进还是阻碍了经济增长——基于技术进步视角的面板分析

金融创新对经济增长的作用方向一直是不明确的,本文旨在解释清楚金融创新影响经济增长的内部机制,并对其进行验证。包括金融创新对微观技术的支持,以及进一步扩展到对宏观经济的影响。通过应用工具变量法对全球的面板数据进行处理,建立以内生经济增长理论模型为基础的计量模型进行实证研究,研究结果表明：在考虑金融创新在经济增长模型中存在内生性的情况下：与金融发展不同,金融创新单独对经济增长的作用方向是不确定的,甚至可能存在显著的抑制作用;而金融创新通过技术进步对经济增长的促进作用是显著的,并且这种作用更多地通过企业的技术进步来体现。     

民间资本供求与民营企业融资:对陕西的实证分析

本文建立在调研和有关资料基础上对陕西现实及潜在的民间资本供求进行测算分析,从总量和结构等方面实证了民间资本供给充足、而民营经济对民间资本的需求欲望非常强烈这一结论,要解除民间资本供求的市场失灵现象,就必须构建以"民资、民用、民管"为原则的内生性融资机制,建立社区民间金融管理组织和社区民间金融市场,选择内生性融资方式,创新其融资产品,实现民间资本供给与民营经济对其需求的有效对接.
