贵州经济增长的影响因素研究:计量模型及实证分析

贵州目前的主要经济指标与全国平均水平相比仍有很大差距.借鉴C-D生产函数,选取物质资本、人力资本以及劳动力作为经济增长的主要影响因素,建立经济增长的模型并对这些因素进行实证分析,得出的结论是:贵州要保持经济的持续增长,需要从树立科学的发展观、加快产业结构调整、重视人力资本投资以提高劳动者素质、降低农村人口比重、加快城镇化进程以及进行制度创新等方面进行努力.     

金融自由化影响经济增长的路径分析

金融自由化理论主张改革政府对金融的过度干预,放松对金融机构和金融市场的限制,增强企业的融资功能,放松利率和汇率的管制使之市场化.本文通过对金融自由化与经济增长关系理论的回顾,分析了金融自由影响经济增长的路径,并结合我国的实际探讨了实行金融自由化所需条件.     

西部农业经济增长的要素分析及对策研究

运用C-D生产函数来测度西部农业生产投入要素对农业总产值增长的贡献率.结果表明,西部农业经济增长主要依靠物质费用的增加和农业科技进步,同时农业科技进步的贡献54%又源于农民文化教育水平的提高.因此,依靠科技进步,提高农民文化水平是促进西部农业经济稳定增长的重要举措.     

数字经济推动区域经济增长的实证研究——基于长江经济带2010-2019年数据

数字经济目前已经成为国民经济发展的重要推动力,研究数字经济对区域经济增长所起到的推动作用具有非常重要的现实指导意义。搭建数字经济发展测评体系和区域经济发展水平测量体系,通过对长江经济带2010-2019年相关指标数据的搜集,测算了长江经济带数字经济发展水平与整体经济发展水平,并对二者之间的耦合关系进行了验证,研究发现,长江经济带的整体数字经济发展水平相对均衡,数字经济对于区域经济增长有显著的推动作用,同时针对长江经济带数字经济助力经济增长给出了管理层面的建议。     

国际贸易、技术进步和中国工业行业的生产率增长

内生增长理论认为技术进步是经济增长最为重要的助推力,推动技术进步的力量是对研发的投资和国际贸易的发展。随着经济贸易与信息技术的飞速发展,社会对国际贸易、技术进步的关注程度日渐提升。通过深入分析国际贸易与工业行业生产率之间的关系,可以有针对性地应用有效手段对国际贸易进行调整,使其可以继续带动技术的进步并促进工业行业生产率的提升。基于此,论文探究了我国国际贸易、技术进步与工业行业生产率增长的关系,阐述了国际贸易、技术进步对于工业行业生产率的真实影响。     

Terrorism and its impact on economic growth and technological innovation

Recent terrorist acts, in particular the 9-11 attacks in 2001, have created disruptions in the global economy. The short-term impact had been felt in the global tourism, airline industries, as well as the financial markets. While the global economy has recovered and is adjusting to the new global realities, the longer-term impact of heightened security risk across the world can be felt in the form of higher risk premiums in asset markets, as well as a shift of resources towards dealing with terrorism. Just as World War II had accelerated the development of nuclear energy as well as a major contributing factor in the genesis of Silicon Valley, the current war against terrorism will affect both the pace and trajectory of technology trends, as efforts are focused on developing technologies to combat terrorism. In this paper, we review the effects of the current war on terrorism in terms of its impact on the economy, the allocation of resources to R&D, and the trajectory of future R&D.     

Institutions and economic growth in Portugal: a quantitative exploration

This paper presents a broad diagnostic of the level of institutional development in Portugal in the legal, corporate governance and financial systems. A comparative assessment suggests that Portuguese institutions are less developed than their European Union and East Asian counterparts, more developed than Greek institutions and on a level similar to that of Spanish institutions. We use data for a wide cross-section of countries since 1960 and correlate indicators of institutional development with the long-term average growth rate, identifying issues where reform is likely to significantly affect economic growth. We construct three new indices that measure the potential of institutional reform - the impact of reform on growth, the required reform effort and the efficiency of reform index - by taking into consideration the institutional distance between Portugal and the European Union. These indices measure, respectively, which reforms have the most payoff in terms of growth, which are less costly to undertake and which deliver the most growth per required effort. Our results strongly suggest that in a large number of issues, institutional reform may translate into substantially higher rates of economic growth. Of the ten most promising reforms, six are in the legal area, irrespective of which of the indices is considered. Whereas legal reform is promising at the aggregate and the microeconomic levels, in the financial sector aggregate indicators offer the wider scope for productive reform, while in the corporate governance area it is indices at the micro level that hold the most promise. These results support the view that a comprehensive reform effort is likely to deliver higher rates of growth in Portugal, allowing faster real convergence with the rest of the European Union.Received: January 2003, Accepted: February 2004, JEL Classification: O0, O5, K00, K4, G2, G3This paper is based on Firms, Financial Markets and the Law: Institutions and Economic Growth in Portugal, prepared for the conference Desenvolvimento Económico Português no Espaço Europeu: Determinantes e Políticas, organized by the Banco de Portugal.

Economic Growth and Transboundary Pollution in Europe: An Empirical Analysis

The existing empirical evidence suggests that environmental Kuznets curvesonly exist for pollutants with semi-local and medium term impacts.Ansuategi and Perrings (2000) have considered the behavioral basis for thecorrelation observed between different spatial incidence of environmentaldegradation and the relation between economic growth and environmentalquality. They show that self-interested planners following a Nash-typestrategy tend to address environmental effects sequentially: addressingthose with the most immediate costs first, and those whose costs aredisplaced in space later. This paper tests such behavioral basis in thecontext of sulphur dioxide emissions in Europe.     

The Middle Class Consensus and Economic Development

A middle class consensus is defined as a high share of income for the middle class and a low degree of ethnic divisons. The paper links a middle class consensus to resource endowments, along the lines of the provocative thesis of Engerman and Sokoloff (1997 and 2000). This paper exploits this association using tropical resource endowments as instruments for inequality. A higher share of income for the middle class and lower ethnic divisions are associated with higher income and higher growth, as well as with more education, better health, better infrastructure, better economic policies, less political instability, less civil war and ethnic minorities at risk, more social modernization and more democracy.     

The nature of the steady state in models of optimal growth under uncertainty

Summary. We study a one-sector stochastic optimal growth model with a representative agent. Utility is logarithmic and the production function is of the Cobb-Douglas form with capital exponent . Production is affected by a multiplicative shock taking one of two values with positive probabilities p and 1-p. It is well known that for this economy, optimal paths converge to a unique steady state, which is an invariant distribution. We are concerned with properties of this distribution. By using the theory of Iterated Function Systems, we are able to characterize such a distribution in terms of singularity versus absolute continuity as parameters and p change. We establish mutual singularity of the invariant distributions as p varies between 0 and 1 whenever . More delicate is the case . Singularity with respect to Lebesgue measure also appears for values such that . For and Peres and Solomyak (1998) have shown that the distribution is a.e. absolutely continuous. Characterization of the invariant distribution in the remaining cases is still an open question. The entire analysis is summarized through a bifurcation diagram, drawn in terms of pairs .Received: 9 April 2002, Revised: 29 October 2002, JEL Classification Numbers: C61, O41.Correspondence to: Tapan MitraThis research was partially supported by CNR (Italy) under the "Short-term mobility" program and by M.U.R.S.T.
