Using data on net exports and factor endowments for more than 100 countries, this paper studies the relationship between factor endowments and comparative advantage in 28 manufacturing sectors between 1975 and 2010. The authors allow for systematic technological differences across countries,...

This paper assesses the effects of knowledge on economic growth. By using an array of indicators, each of which represents an aspect of knowledge, as independent variables in cross-section regressions that span 92 countries for the period 1960 to 2000, they show that knowledge is a significant...

Recent empirical studies question conventional wisdom about the importance of education to growth. These results partly reflect how international differences in the quality of education systems--defined by the systems' ability to produce one marginal unit of productive human capital--are not...

Changing population age structures are shaping the trajectories of development in many countries, bringing opportunities and challenges. While aging has been a matter of concern for upper-middle and high-income economies, rapid population growth is set to continue in the poorest countries over...

Links between social capital, human capital, and product imitation are studied in an overlapping generations model of endogenous growth where the key benefit of social capital is to promote imitation. There is also a two-way interaction between imitation and human capital. Building social...

The authors present a model of endogenous growth in which the main engine of economic development is knowledge. Using a two-sector closed economy model that comprises of a conventional goods-producing sector and a research and development sector, their model incorporates two key aspects of...

Given that public spending will have a positive impact on GDP if the benefits exceed the marginal cost of public funds, the present paper deals with measuring costs and benefits of public spending. The paper discusses one cost seldom considered in the literature and in policy debates, namely,...

This paper presents a small-scale intertemporal model of endogenous growth that accounts for the composition of public expenditure and externalities associated with public capital. Government spending is disaggregated into various components, including maintenance, security, and investment in...

Mainstream economics views demographic changes in the structure of households as of little relevance for the behavior of firms or the functioning of markets. The present paper dispels this view by arguing that changes in the number of non-workers could affect the intensity with which consumers...

This paper uses firm-level data to assess whether telecommunication services are general-purpose technologies (technologies that benefit a large segment of the economy and have long-lasting effect). It finds that only Internet services are so: firm growth and productivity are much higher when...
