Natural resource dependence, non-tradables, and economic growth

I argue that the commonly used nominal measure of natural resource dependence – the share of exports of primary products in GNP – understates in growth regressions the negative link between natural resource dependence and per capita GDP growth. I show that using a purchasing power parity adjusted measure yields an economically much larger negative relationship between per capita GDP growth and natural resource dependence than what has been suggested by the nominal measure. Consistent with the rent-seeking literature, I show that the resource curse is a symptom of societies characterized by high levels of corruption and sluggish checks and balances on political decision-making.     

健康、教育与经济增长

健康与教育是人力资本诸多形成方式中最重要的两种,长期以来内生增长理论强调和重视教育人力资本对于经济增长的贡献和作用,但健康与教育之间的相互影响以及健康人力资本对于经济增长的作用却未得到应有的重视。基于此,本文在Lucas(1988),Van Zon和Muysken(2001)模型基础上,构建了一个包含最终产品、健康和教育的三部门模型。静态均衡、转移动态和仿真实验的结果表明:在总体人力资本的形成过程中,健康对广义人力资本的贡献份额大于教育;健康的增量而非健康人力资本存量水平有利于长期经济增长;健康的改善必须同时辅以教育人力资本的提高才能促进经济增长;政府公共健康支出对于健康人力资本的形成具有重要作用,有助于促进发展机会的均等和减贫;重视人力资本积累的经济体在10-15年后会呈现明显的经济绩效的改善。     

略论经济增长由单纯依靠投资和净出口向二者与消费协调拉动的转变

在国内持续低消费的情况下,由于政府对投资和出口的过度激励,中国长期以来形成了主要依靠投资、净出口拉动的经济增长。主要依靠投资、净出口拉动的经济增长是不可持续的。实现经济增长主要依靠投资、净出口拉动向依靠消费、投资、净出口协调拉动转变的关键：一在于提高消费,二在于改变政府对投资和出口激励的方式与手段。     

马克思的经济增长理论模型

马克思经过二十多年的科学拓荒,独立地开辟了后来被称为经济增长理论的新领域。在经济增长理论史上,马克思第一次将静态分析动态化、短期分析长期化,建立了第一个经济增长理论模型。马克思主义经济学家费里德曼以马克思经济增长理论模型为根据,建立了第一个经济增长数学模型。研究马克思经济增长理论模型以及后来马克思主义经济学家据此建立的经济增长数学模型,借鉴西方经济增长模型中的合理因素,从实际出发,深入探索相关理论和现实问题,对弘扬和发展马克思主义经济增长理论具有重大意义。     

Systemic technology policies: Issues and instruments

In this Introduction, we review the arguments that underpinned the workshop on which the special section is grounded and provide a structured sequence for the contents of the seven selected papers that comprise the section.     

Capitalism's growth imperative

A capitalist firm operating in a competitive market is subjectto a growth imperative, because uncertainty about the profitrate under a no-growth policy makes the firm's prospects highlyunattractive in finite time and bankruptcy practically certainin the long run. A no-growth policy determines consumption andinvestment so that they and capital would remain constant overtime if the latter's expected return were realised with certainty.Simulation is used to arrive at the probability of bankruptcyby the end of t periods and the expected values of capital andmoney, for relevant combinations of time and uncertainty undersuccessively more realistic models of a no-growth firm in acompetitive market. The sensitivity of the results to variationin the parameters in each of the models is evaluated. Finally,we establish that a plausible growth policy may achieve growth,but the problem of bankruptcy is not resolved.     

Pollution and life expectancy: How environmental policy can promote growth

This article investigates the influence of environmental policy (EP) on growth in an AK-type growth model, when finite lifetime is introduced and the link between pollution and life expectancy (through the detrimental impact of pollution on health) is taken into account.Using an overlapping generations model à la Blanchard [Blanchard, O. (1985). Debt, deficits and finite horizon. Journal of Political Economy, 93:223-247], we demonstrate that finite lifetime introduces a “generational turnover effect” which modifies the influence of the EP on growth. Thus, when lifetime is finite and independent from pollution, we show that the “generational turnover effect” limits the detrimental impact of the EP on growth, if agents smooth their consumption over time. When pollution negatively influences life expectancy through health, we demonstrate that the “generational turnover effect” is magnified and that the EP and growth have an inverted U-shaped relationship in the steady-state. In this case, we show that the environmental policy is more likely to promote growth (i.e. it stimulates growth for a wider range of environmental taxes) when the impact of pollution on health is important and/or public expenditures in health are low. Finally, using numerical simulations, we find that for the value of parameters that we have chosen, the EP will be more likely to promote growth when agents smooth consumption over time.     

软件企业智力资本对企业成长的影响机制研究

在知识经济时代,企业的竞争优势已经从土地、资金转向企业拥有的知识、技能、经验,即企业的智力资本,在软件业,智力资本的地位尤为重要,本文的目的是探讨智力资本对软件企业的成长机制,认为顾客资本是整个智力资本的关键,智力资本的其他的维度通过顾客资本促进企业成长,而企业的过程资本则对智力资本与企业成长的关系具有调节作用。     

Economic gains from technology-intensive trade: an empirical assessment

National investment in technological activity is commonly justifiedin terms of the positive impacts upon productivity, internationalcompetitiveness and related aspects of national economic performance.This premise has found a supportive theoretical framework inthe new technology and growth models. Based on extended technology-gapmodels, this study examines cross-country empirical evidenceon the relationship between technology-intensive trade performance(as a proxy for technological output) and per capita economicperformance, utilising 1978 to 1992 data for around 45 nations.The results provide some support for a positive relationshipbetween trade performance and economic returns. However, theweak and often inconsistent results suggest that the unconditionalpursuit of technology-intensive trade improvements may not necessarilyhave the expected net benefits.
