Research and development in the growth process   总被引:9,自引:2,他引:9  
This paper introduces into Schumpeterian growth theory an important element of heterogeneity in the structure of innovative activity—namely, the distinction between research and development. We construct a simple model of growth to investigate how the (steady-state) rate of growth affects and is affected by the relative mix between research and development. Although we assume for simplicity that the total supply of innovative activity is given it turns out that, with one important exception, the growth rate responds to most parameter changes in the same way as in previous models where growth was determined by the total amount of innovative activity. In particular, the level of research tends to covary positively with the rate of growth, even in the extreme case where the general knowledge that underlies long-run growth is created only by secondary innovations arising from the development process. The exception concerns the effects of competition on growth. Although simpler Schumpeterian growth models implied that increased competition would reduce growth by reducing the incentive to innovate, introducing the distinction between research and development implies that this effect is likely to be reversed.  相似文献

After a decade of research on the relationship between institutions and growth, there is no consensus about the exact way in which these two variables interact. In this paper we re-examine the role that institutions play in the growth process using data for developed and developing economies over the period 1975–2005. Our results indicate that the data is best described by an econometric model with two growth regimes. Political institutions are the key determinant of which regime an economy belongs to, while economic institutions have a direct impact on growth rates within each regime. These findings support the hypothesis that political institutions are one of the deep causes of growth, setting the stage in which economic institutions and standard covariates operate.  相似文献

美国由建国初的殖民地小农经济转变为近代化农业经济只用了80年时间.通过分析美国农业近代化的形成过程,可以找出其由自给自足的小农经济向近代资本主义大农场经济快速转变的内部规律与动因.西进运动、工业革命、南北战争这三个有利条件是美国农业近代化形成的直接动因,而小农经济与大农场经济交替发展是其特点.  相似文献

政府在农业现代化中具有重要作用,这不仅是理论判断同时也是发达国家农业现代化实践的经验总结。中国政府在农业现代化过程中发挥了积极的作用,同时也存在许多不足。政府应在农业立法、资金投入和服务组织等方面加强其主导作用。同时,要处理好政府与市场、政府与农民以及政府与农业协作组织之间的关系。  相似文献

This paper develops a dynamic theory that accounts for the evolution of trade policy, underlying internal class conflicts, and output growth performance. Analysis of political responses to the distributional effects of international trade reveals that economies with a comparative advantage in manufacturing may reach a developed stage through the ebb and flow of protectionism. This nonmonotonic evolution of trade policy is consistent with the historical experience of Western Europe over the last few centuries.  相似文献

现代工业文明作为一把利弊并存的“双刃剑”,在赢得巨大面效应的同时,也引发种种负面效应,其严重程度可以使其被称做“现代病”,并非危言耸听,归结起来便是工业文明诞生以来日益滋长起人类自大症和急功近利,及时行乐的短视症,加之现代人掌握了空前强大的工具理性,由自然,社会,人文三重因素组合对生态环境造成渐趋加重的毁损。使人类文明发展的可持续性面临严重挑战。  相似文献

Business groups are an important aspect of the industrial organization of many developing countries. This paper develops a theory suggesting that they may be organizations that facilitate modernization in the presence of financial market constraints. An important function of the stockmarket is the diversification of risk that comes with specialized, productive technology. But in the face of serious information problems a well functioning stockmarket may fail to emerge, relegating the economy to a low productivity‐poverty trap. Bilateral links between a firm and a group of others may be a more cost effective way to achieve risk‐sharing. Such business groups may be feasible when a full‐fledged stockmarket is not. As modernization takes place, either because information problems become less severe or more firms enter the economy, business groups actually expand in size before being abruptly rendered obsolete by the stockmarket. This is consistent with empirical results from a number of emerging economies.  相似文献

The impact of privatization on economic growth has been little investigated relative to disaggregated approaches. A growth accounting framework is used here to investigate the impact of privatization on growth for the Australian economy. The contribution of public capital to the private sector and whether the growth process is endogenous or Solow is evaluated. Separate measures of public and private capital are computed in order to estimate their impacts with labour on Australian gross domestic product (GDP) growth for the period 1960 to 2003. A simple growth rates version is found preferred by stationarity and other tests. Labour growth appears to strongly positively influence the growth of GDP. In contrast, public capital growth has no statistically significant effect on GDP growth, or on private capital productivity. The data are consistent with the hypothesis that the coefficients of the growth equation are the same before and during privatization.  相似文献

This research suggests that a Darwinian evolution of entrepreneurial spirit played a significant role in the process of economic development and the dynamics of inequality within and across societies. The study argues that entrepreneurial spirit evolved non-monotonically in the course of human history. In early stages of development, risk-tolerant, growth promoting traits generated an evolutionary advantage and their increased representation accelerated the pace of technological progress and the process of economic development. In mature stages of development, however, risk-averse traits gained an evolutionary advantage, diminishing the growth potential of advanced economies and contributing to convergence in economic growth across countries.  相似文献

Do all countries follow the same growth process?   总被引:1,自引:0,他引:1  
We estimate finite-mixture models in which countries are sorted into groups based on the similarity of the conditional distributions of their growth rates. We observe countries growth experiences over the 1970–2000 period and find evidence for a model in which there are two classes of countries, each with its own distinct growth regime. Group membership does not conform to the usual categories used to address parameter heterogeneity such as region or income. We find strong evidence that the quality of institutions and specifically, the degree of law and order, helps to sort countries into different regimes. Once we control for institutional features of the economy, we find no evidence that geographic features such as latitude and being landlocked play a role in determining the country groupings.  相似文献

This essay formalizes the model of international growth advanced by W. Arthur Lewis in his 1979 Nobel Prize address and by Ragnar Nurkse in the 1950's. Both of them employed the model to support their respective cases for pursuit of a ‘balanced growth’ strategy by the LDC's. The purpose of the formalization undertaken here is to examine the theoretical consequences for the secular ratio of LDC to MDC incomes as the Lewis-Nurkse growth process unfolds. The paper explores whether or not growth in Lewis-Nurkse fashion must mean persistent poverty for the LDC's. In addition, the formalization provides an explicit characterization of economic ‘dependence’.  相似文献

We present an endogenous growth model with human capital and learning by doing. Human capital is not an input factor in the production process of final output but it affects the ability to build up knowledge capital as a by‐product of cumulated investment (learning by doing). Human capital is formed in the schooling sector that is financed by the government. The government may run into debt but obeys the inter‐temporal budget constraint. The article analyzes the structure of the model and studies the effects of different budgetary policies as regards the balanced growth rate, transition dynamics and with respect to welfare.  相似文献

Summary. We formulate an optimal estimation process in a stochastic growth model with an unknown true probability model. We consider a general reduced model of capital accumulation with an infinite horizon and introduce a learning process in the stochastic dynamic programming. When the only available information is a sample realization generated by a stationary and ergodic stochastic process, we prove that the optimal estimation process based on likelihood-increasing behavior converges to the true probability measure and the likelihood-increasing estimator defines a transition function on the sample space.Received: 24 January 2004, Revised: 18 February 2005, JEL Classification Numbers: C13, C44, C61, O41.An earlier version of this paper was presented at the annual Meeting of the Japanese Economic Association at the University of Tokyo, at the annual Conference of the Japan Society for Industrial and Applied Mathematics at Keio University, and at the 7th Czech-Japan Seminar on Data Analysis and Decision Making under Uncertainty in Awaji Island.

This article investigates the process of reducing poverty in ethnic minority households. Using two recent Vietnam household surveys, we find that ethnic minority households are more likely to be persistently poor and less likely to be persistently non-poor than ethnic majority households. The within-group component generated by the variation in income within each ethnicity group explains more than 90% of the change in total inequality. Income redistribution plays an important role in decreasing the poverty gap and decreasing poverty severity. Different ethnic groups have different poverty patterns, which should be noted when designing policies to alleviate poverty and inequality.  相似文献
