Recent biomedical research shows that roughly three-quarters of cognitive abilities are attributable to genetics and family environment. This paper presents a growth model that characterizes the role of the intergenerational transmission of genes and the effect of family environment on growth trajectories. If the average human or physical capital stocks are sufficiently low, the model shows that the economy will be caught in a poverty trap. Conversely, countries with more resources will converge to a bala nced growth path where the average rate of genetic transmission of skills from parents to children determines the long-run rate of output growth. Increased genetic diversity (or income inequality) is shown to raise the fertility rate and reduce output growth in the transitional dynamics. Thus, nature and nurture are able to explain a variety of countries' growth experiences.  相似文献

This paper proposes a two-group urban model with endogenous capital and knowledge accumulation in an isolated island economy. The model examines the dynamic interdependence among knowledge utilization, creativity, transportation conditions, savings behavior, location choice, and residential pattern in a just two-group island economy. Although it is constructed with some strict assumptions, the model is quite general in the sense that the well-known models, such as the Solow-Swan model, the Kaldor-Pasinetti two-group model, and the Alonso model, can be considered, from a structural point of view, as its special cases. The knowledge accumulation in our model is based upon Arrow's learning-by-doing model. It is proved that the system may have a unique or multiple equilibria and each equilibrium may be stable or unstable, depending upon knowledge utilization and creation characteristics of the two groups. We also examine the impact of changes in the population and knowledge creation efficiency of two groups on long-run growth, wealth distribution, and residential structure.  相似文献

This paper asks how much does physical capital contribute to economic growth. It postulates that capital is heterogeneous because of embodied progress, and it structures the inquiry to account for differences in economic development. Embedded in data that cover 120 nations over 41 years are 35 derived capital stock series, whose characteristics include average ages stratified by development state. Growth accountancy proceeds by regression analysis cast in a production function context and repeated for each capital type. Those results help to establish the growth contributions of labor quantity and quality and capital quantity and quality. They also bear on neoclassical convergence.  相似文献

With panel data for 28 Chinese provinces (autonomous regions, municipalities) during 1985–2002, this paper assesses the effect of banking structure on economic growth. Banking structure is defined as the relative importance of banks of different size in the banking sector. The market share of small banking institutions is taken as a proxy to measure the banking structure. In dealing with the potential endogeneity problem, this paper constructs an instrumental variable for banking structure with the information on the commercialization reform of state-owned banks initiated in 1994. The estimation results from a two-way fixed-effect model show that increases in the market share of small banking institutions enhance economic growth in contemporary China.  相似文献

Dollarization brought price stability and higher economic growth to Ecuador. Nevertheless, unemployment remained stubbornly high. Two opposing forces explain this result: sustained growth led to higher labor demand but price stabilization triggered substitution effects by cheaper intermediate goods and capital.  相似文献

Institutions, infrastructure, and economic growth   总被引:4,自引:0,他引:4  
This paper develops a structural model of infrastructure and output growth that takes account of institutional and economic factors that mediate in the infrastructure–GDP interactions. Cross-country estimates of the model indicate that the contribution of infrastructure services to GDP is substantial and, in general, exceeds the cost of provision of those services. The results also shed light on the factors that shape a country's response to its infrastructure needs and offer policy implications for facilitating the removal of infrastructure inadequacies.  相似文献

It is argued that the explosive growth experienced in much of the World since the middle of the 19th Century is due to the exploitation and use of fossil fuels which, in turn, was made possible by capital good innovations that enabled this source of energy to be used effectively. Economic growth is viewed as the outcome autocatalytic co-evolution of energy use and the application of new knowledge associated with energy use. It is argued that models of economic growth should be built from innovation diffusion processes, unfolding in history, rather than from a timeless aggregate production function. A simple ‘evolutionary macroeconomic’ model of economic growth is developed and tested using almost two centuries of British data. The empirical findings strongly support the hypothesis that growth has been due to the presence of a ‘super-radical innovation diffusion process’ following the industrial deployment of fossil fuels on a large scale in the 19th Century. Also, the evidence suggests that large and sustained movements in energy prices have had a very significant long term role to play.  相似文献

ABSTRACT

Taking the data of 20,863 patents in the field of Artificial Intelligence between 2000 and 2018 as an example, this paper examined the relationships among organisations’ knowledge structure, network structure, exploratory innovation and exploitative innovation. The results show that organisations’ knowledge combinatorial potential and knowledge diversity have positive effects on both exploratory innovation and exploitative innovation. Organisations’ degree centrality and structural holes in the collaboration network can partly mediate the relationships between their knowledge structure and exploratory and exploitative innovations.  相似文献

Relative consumption, economic growth, and taxation   总被引:1,自引:0,他引:1  
This paper studies the influence of consumption externalities in the Ramsey model. In contrast to the recent literature, a quite general specification of preferences is used and the concept of the effective intertemporal elasticity of substitution is introduced. We give conditions for the observational equivalence between economies with consumption externalities and externality-free economies. An additional key result is that there exist several types of instantaneous utility functions in which the decentralized solution coincides with the socially planned one in spite of the presence of consumption externalities. The conditions for optimal taxation are also derived.  相似文献

Entrepreneurship, structural change, and economic growth   总被引:1,自引:0,他引:1  
The ability to adjust to structural change is vital to economic development, and entries can be active participants in this process. While the importance of factor reallocations for growth is widely discussed, the role of entrepreneurs in managing these reallocations is currently not well understood. This paper analyzes the role of entry activity for adjustments of the sectoral structure and its relevance for regional economic development. The historical framework is the accelerated economic transformation that occurred in industrialized countries during the mid 1970s, resulting in an increasing need to adjust. Based on German data from 1975 to 2002, evidence is presented that sectoral reallocations are an important means for transforming entrepreneurial activity into growth.  相似文献

Conspicuous consumption, economic growth, and taxation   总被引:5,自引:0,他引:5  
Commodities do not only serve the purpose of satisfying direct needs in the production and consumption process. Some of them are also used to display social status and to affect the position of an individual in society. The paper looks at status-seeking activities in an economic-growth context. Two questions are asked. Does status-seeking behavior accelerate economic growth? And: should capital accumulation be subsidized to correct for the status externality? The answers to both questions are ambiguous.  相似文献

In this paper, we study the relationship between competition and economic growth using a model of economic development through the creation of new sectors. In our model, competition has both an intra- and an inter-sector component. We find that the best conditions for economic development are achieved when a suitable ratio of inter- to intra-sector competition is achieved. This ratio constitutes a compromise between providing a temporary monopoly to the first entrepreneur (low inter-sector competition) and creating enough imitation to expand the sector (intra-sector competition).  相似文献

This paper analyzes the issue of money superneutrality through an intertemporal optimizing model of capital accumulation with endogenous fertility, i.e. endogenous population growth. Two elements of this setup invalidate money superneutrality: (i) a demand for fertility that depends on real money balances, and (ii) an inverse relation between capital–labor ratio and population growth. Higher monetary growth increases fertility, since it reduces its opportunity cost, and hence diminishes capital intensity, and per capita output. This reverse Tobin effect is matched by an increase in aggregate capital and output growth rates. In this framework, the optimal monetary growth rule is a “distorted Friedman rule”.  相似文献

We develop a new model that links credit contracts enforcement to banking emergence and economic growth. It is shown that the development process is composed of three stages. In the first stage, the economy develops slowly due to a primitive technology of capital accumulation. The second stage marks the emergence of banking and the substitution of the primitive technology by a more productive modern technology that enhances growth. Finally in the third stage, our model enables the realization of a dynamic capital accumulation scenario without credit rationing. Another finding is that a reduction in the enforcement cost accelerates the emergence of the banking system.  相似文献

Rebelo’s two-sector endogenous growth model is embedded within a two-country international trade framework. The two countries bargain over a trade agreement that specifies: (i) the size of the foreign aid that the richer country gives to the poorer one; (ii) the terms of the international trade that takes place after the aid is given. Foreign aid is given not because of generosity, but because it improves the capital allocation across the world and thus raises total world production. This world production surplus enables the rich country to raise its equilibrium consumption and welfare beyond their no-aid levels. To ensure it, the rich country uses a trade agreement to condition the aid on favorable terms of trade.  相似文献

This paper introduces the different kinds of franchise contract bargaining into a macroeconomic model and accordingly researches the relationship between competition and economic growth. In Nash bargaining model/vertical integration we find an inverted-U shaped or a monotonically increasing relationship between the competitive degree of the intermediate goods market and economic growth. In bargaining of the right to manage model/vertical non-integration our result shows an inverted-U shaped or a monotonically decreasing relationship between the competitive degree of the intermediate goods market and economic growth. In addition, there is an overall negative relationship between the competitive degree of the final goods market and economic growth. Especially, our interesting findings that the pricing rule for intermediate goods firm depends not only on market power but also bargaining power are more general. Therefore, we can further explain the firms' vertical control strategy.  相似文献

Environment, human development and economic growth   总被引:7,自引:0,他引:7  
Over the last few years, environmental issues have entered into policy design, particularly development and growth policies. Natural resources are considered necessary production inputs and environmental quality is considered a welfare determinant. The integration of environmental issues into economic growth and development theories and empirics is currently widely analyzed in the literature. The effects of natural resources endowment on economic growth are mainly analyzed through the so-called Resource Curse Hypothesis (RCH) whereas the effects of economic growth on environmental quality are part of the Environmental Kuznets Curve (EKC). Furthermore, recent contributions on RCH and EKC have shown the important role of institutions and human development dimensions in building a sustainable development path. In this paper, we attempt to analyze the causal relationships between economic growth, human development and sustainability combining the RCH and EKC models and adopting a human development perspective. Results confirm the importance of high institutional quality and investments for human capital accumulation in order to build a sustainable development path.  相似文献

Empirical evidence shows that the number of patents per R&D dollar declines with firm size. In this paper, we propose a Schumpeterian growth model that accounts for this evidence. We analyze an economy with firms that engage in cost-reducing innovation resulting from the accumulation of both codified and tacit knowledge: the former occurs through the purchase of patents, while the latter is the result of R&D conducted in-house by firms. We study the relation between knowledge appropriability and market structure, and we show that a shift from patents to in-house research occurs as firm size gets larger. Since innovation statistics concentrate mainly on patents, this process of research reallocation results into an under-estimation of innovative activity and is responsible for the declining ratio of patents to R&D expenditure. Survey data on UK-based firms provide support to our results.  相似文献

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.  相似文献
