Learning-by-doing versus Schooling in a Model of Endogenous Growth

A two sector model of learning-by-doing measured by means of production aggregated over time and of human capital accumulation in a schooling sector is presented. Time utilization is rival between schooling and learning-by-doing. Depending on the sum of elasticities of the accumulated factors (i.e., of production experience and educational human capital) in both sectors, a situation with or without endogenous growth results. Dynamic optimization of the choice between leisure and working and of the division of human capital between education and production is executed. Transitional dynamics are analyzed for a Cobb-Douglas example and a numerical simulation is performed.JEL classification: C61, D90, O41.Acknowledgements The author would like to thank Eric C.

存款保险制度的产生发展及其理论基础

本文通过对存款保险制度在国际上产生发展的背景分析 ,发现该制度在实践中有内在的必然性 ,在理论上有坚实的基础 ,银行的存在是金融效率所在 ,尽管挤兑可能会发生甚至迅速演化为银行危机 ,但不能否定银行的客观必要性。相反 ,需要防止挤兑和银行危机发生的制度安排 ,其中没有任何一种安排能够取代存款保险制度。中国现在比以往任何时候都需要采纳这一制度以适应市场化金融改革开放的需要 ,当然相应的技术问题仍需要解决。     

Persistence of Shocks to Output in Austria and Theories of Economic Growth

The paper analyzes the degree of output persistence in GDP in order toempirically discriminate between the Solow growth model, the perfect competition endogenous growth model and the imperfect competition endogenous growth model for the case of Austria. Wefind that a shock in the growth rate of output induces a permanent and larger effect on the level of GDP. This leads us to refute the Solow growth model and the perfect competition model of endogenous growth.We may not reject the imperfect competition growth model.     

Oil Crisis,Market Reforms,and Human Welfare： An Econometric Analysis of the Australian Economy

As an active trader in international crude oil and petroleum product markets, Australia＇s human welfare is affected by oil crisis and contagion from the perspectives of economic growth, income inequality, and environmental sustainability. This paper investigates the impacts of oil price shocks upon Australia＇s gross domestic product （GDP） growth, Gini coefficients, and carbon dioxide emissions per capita from 1970 to 2012 with yearly frequency. Hypotheses concerning whether Australia＇s economic immunity against oil crisis is affected after the deregulation of oil market and whether endogenous oil price shocks account for more variations in human welfare than exogenous oil price shocks are tested. The methodologies include a theoretic model and a series of econometric tests. For the short-run dynamics, oil price is integrated into the model both linearly and non-linearly. Oil price shocks are categorized into exogenous and endogenous shocks. The conclusions are that inflated oil prices exert mainly non-linear negative impacts upon human welfare indicators and exogenous shocks induce endogenous shocks through labor price, Consumer Price Index （CPI）, interest rate, and exchange rate. For the long-run equilibrium, non-linear shocks＇ effects decay more slowly than linear shocks and the impacts of endogenous shocks last longer than that of exogenous shocks. Finally, oil market policies are evaluated and proposed.     

教育、知识发展与经济增长

经济增长是宏观经济学的重要研究领域.近年来,内生经济增长理论得到了很大的发展.经济学家逐渐认识到人力资本投资、研究与开发活动对经济增长的重要作用.本文在卢卡斯和琼斯等人关于内生经济增长模型的基础上,提出了一个改进的内生经济增长模型.模型推导结果表明,平衡的经济增长取决于人力资本积累以及通过研究与开发活动导致的新知识、新技术的积累.平衡经济增长的速度快于知识和技术积累的速度,知识和技术积累的速度又快于人力资本积累的速度.教育是积累人力资本的最重要的方式,知识的发展需要研究和开发活动.为了实现快速的、稳定的经济增长,政府应重视教育和研究与开发活动.     

丝绸之路河西走廊物流业效率演化分析

构建了分析河西走廊物流业效率演化的指标体系,基于2009-2017年河西走廊物流业统计数据,运用DEA-Malmquist指数法测算了各市物流业效率和技术进步率,采用Tobit回归模型分析了该地区物流业效率的影响因素,并从省内、省域间、各经济区域间三个方面进行了对比分析。实证分析表明,相较于全国各省市地区,河西走廊物流业整体水平较低,物流业效率和技术进步率的强正相关性普遍存在,其物流业发展对政策偏向具有较强的依赖性;同时,技术进步率低下和基础设施匮乏也是制约物流业发展的重要因素。基于此,从政策照顾与资金投入、科技进步与管理水平和市场运营与体系建设三个方面,为河西走廊物流业发展提出了建议与改善措施。     

长三角区域自主创新及利用FDI的关系研究

利用FDI为引资地区提高自主创新水平创造了一个高级的开放式创新平台,自主创新能力的提升为吸引高质量的FDI提供了必要条件。因此,自主创新与利用FDI是相辅相成的。本文通过实证分析长三角各省市的自主创新及利用FDI的协整关系,发现长三角各省市的自主创新和实际利用FDI之间既存在正的、也存在负的长期均衡关系。据此建议,加大高质量FDI引进力度,提升长三角科研人员的创新能力,加大研发经费投入,加强本土公司创新产出的成果转化能力。     

Informal Property Rights as Relational and Functional: Unravelling the Relational Contract in China's Informal Housing Market

In the face of state-led land grabs, enterprising Chinese peasants have started a revolution in the ambiguous and insecure rural tenure system by developing an extralegal property system known as the small property right (SPR). Using the SPR, peasants are able to capitalize on their property through the sale of houses built on collectively owned land. Little is known, however, about the specific process behind the development of the SPR by the peasants, or how this extralegal property system functions in terms of securing the use and transfer of property without the backing of law. This article aims to clarify the situation through the lenses of the Endogenous Nature of Institutions and Relational Contract Theory, aiming to understand the socially constructed, endogenous and relational nature of the property rights that make SPR functional. Based on an ethnographic investigation of Beijing's largest SPR housing settlement, we show how enterprising peasants develop long-term relational contracts with urban households for the provision of housing services, secured on the basis of the common interests and symbiosis of the two parties and a reputation system that serves to deter defaults. The discretionary treatment of SPR housing by local states serves as a further motivation for the village and the informal homeowners to preserve a stable property arrangement, with such a specific institutional setting being an exemplar of China's pragmatic state entrepreneurialism.     

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.     

公司治理效率、动态内生性与非效率投资——基于动态性视角的经验研究

本文以2002—2011年716家上市公司为样本,运用动态面板的System GMM估计方法,同时考虑了三种内生性,以动态性的视角研究了公司治理效率与公司非效率投资间的关系。通过研究,得到以下结论：（1）前期和当期公司治理效率都与当期公司非效率投资负相关;（2）公司治理效率对公司非效率投资影响的持续时间大约为4年;（3）前期公司非效率投资对当期公司治理效率有显著的正向反馈效应;（4）公司治理效率与公司非效率投资间存在动态内生性;（5）公司的非效率投资不仅有损于公司的当期价值,而且也不利于公司的未来价值。
