We analyse the implications for the dynamics of capital accumulation of market power and endogenous demand elasticities, in an environment in which the latter are affected by the number of competitors in each industry. In equilibrium the interest rate increases as capital accumulates, even...

We develop a simple growth model with imperfect competition in which demand conditions can affect the dynamics of capital accumulation, hindering or enhancing growth. In our model the elasticity of the demand schedule faced by a typical firm depends on the aggregate savings rate. The latter...

The paper investigates the local dynamics of a simple growth model with a public health factor. A notable feature of the model is that it employs a non-separable utility function between consumption and the level of public health infrastructure (publicly provided health environment). In addition...

This paper looks at the interplay between human capital and innovation in the presence of climate and educational policies. Using recent empirical estimates, human capital and general purpose R&D are introduced in an integrated assessment model that has been extensively applied to study the...

We build an overlapping generations model in which reproductive households face a child quantity–child quality trade-off and bureaucrats are delegated with the task of delivering public services that support the accumulation of human capital. By integrating the theoretical analyses of...

I propose a new explanation for the large productivity gaps between agriculture and nonagriculture observed in developing countries, namely that the elasticity of substitution between skilled and unskilled workers is higher in agriculture than in nonagriculture. I estimate the elasticities in a...

This paper studies the efficient taxation of factor income in infinite-lived models with elastic fertility choices. Two models are considered, one with physical capital only, and one with physical and human capital. In the model with physical capital only, capital income should be subsidized,...

This paper examines the macroeconomic effects of environmental tax reform in a growing economy. A model of endogenous growth based on human capital accumulation is used to simulate numerically the growth effects of different environmental tax reforms and calculate their impact on welfare in the...

The technology club literature suggests a tripartite segmentation of countries into an innovation, an imitation and a stagnation club. We use a Benhabib–Spiegel type growth model embedded in a threshold regression framework to test for non-linearities in the impact of the technology gap on...
