We derive the aggregate normalized CES production function from idea-based microfoundations where firms are allowed to choose their capital- and labor-augmenting technology optimally from a menu of available technologies. This menu is in turn augmented through factor-specific R&D. The considered...

I broadly summarize the theoretical and recent empirical literatures on human development. Using Gray and Purser’s 1970-2010 database of human development index (HDI) components (income, life expectancy, literacy, gross enrolment ratios) for 135 countries, together with indicators of the...

Abstract. We put forward a tractable, interpretable, and easily generalizable framework for modeling endogeneous factor-augmenting technology choice by monopolistically competitive firms. The setup is framed within the standard Dixit and Stiglitz (1977) model of monopolistic competition. Optimal...

This paper examines the relation between aggregate elasticity of substitution (AES) and capital accumulation (the AES-K relation) in a general multi-sector Solow growth model with all CES production technologies. There are two intermediate goods produced by capital and labor, while the final...

Using a normalized CES function with factor-augmenting technical progress, we estimate a supply-side system of the US economy from 1953 to 1998. Avoiding potential estimation biases that have occurred in earlier studies and putting a high emphasis on the consistency of the data set, required by...

Why doesn’t capita flow to developing countries as predicted by the neoclassical model? Is the explanation simply that cross-country marginal productivity of capital (MPK) is equalized, and if so, why? We revisit these issues by unpacking MPK into its public and private components, since there...

Despite the widely recognised importance of the manufacturing industry for successful development relatively few studies empirically investigate this sector in cross-country analysis. In this paper we attempt to fill this gap in the literature by investigating manufacturing production across a...

We analyze the transitional dynamics of an endogenous growth model with heterogeneous consumption goods. In this model, convergence is driven by two different forces: the diminishing returns to capital and the growth of the relative price between physical and human capital. Because this second...
