In this note we study the distortions in an endogenous growth model developed by Grimaud and Tournemaine (2007), where new pieces of knowledge are produced in a R&D sector and used to reduce pollution emissions. Using this model along with a realistic calibration, we conclude that the economy...

The way in which natural and physical capital are accumulated, distributed and harnessed underpins the functioning and sustainability of the productive system of each society as well as its social stratification. Significant changes in the interactions between natural and physical capital...

Vulnerability to reduction of natural capital depends on defensive substitution possibilities that, in turn, are affected by the availability of other productive factors. However in several developing countries asset distribution tends to be highly skewed. Taking into account these elements,...

This paper examines how relative factor endowments and population growth rates affect growth rates in less developed countries. To answer these questions an extension of the Uzawa-Lucas endogenous growth model is used. The paper proves the existence and uniqueness and of the modified model and...

This study is a short note designed to underline the importance of using the theoretically required form of accumulation functions. It is now a common knowledge that a growth model must rely on non-diminishing returns to a factor of production in order to generate endogenous growth. In Lucas...

The relationship between education and economic growth has been one of the fundamental themes of economic analysis. Despite the growing interest in the relationship between growth and education, and despite the strong theoretical foundations for a key role of education/human capital in economic...

We analyze the relationship between inequality and economic growth from two directions. The first part of the survey examines the effect of inequality on growth, showing that when capital markets are imperfect, there is not necessarily a trade-off between equity and efficiency. It therefore...

In 1960 Theodore Schultz expounded a human capital theory of economic growth that includes three elements: 1) Countries without much human capital cannot manage physical capital effectively, 2) Economic growth can only proceed if physical capital and human capital rise together, and 3) Human...

This article presents revised estimates of the external rates of return on investment in schooling provided in “Schooling and National Income: How Large Are the Externalities?” The analysis is based on data for the same set of countries, but it incorporates methodological improvements that...
