What determines the direction of technological progress is one of the central questions that economics needs to answer. By introducing a small but fundamental generalization of Acemolgu (2002) the current paper points out the key determinants of that direction. The extended model argues that...

Based on a general growth model, this paper finds that the steady-state direction of technological progress is determined by the scale return of the production function and the relative factor supply elasticities. A specific version of that model extends Acemoglu (2002) to provide the underlying...

The sectoral composition of the US economy has changed dramatically in the past six decades. At the same time, knowledge and information assets are becoming increasingly important in the value creation process of a modern economy. This paper aims to explain the recent sectoral structural change...

Structural change is a relatively simple (continuous) process having restricted limit-properties. All processes which can be classified as "structural change" inherit these limit-properties. Limit-properties of processes play an important role in neoclassical growth theory. We show that (i) many...

A novel parameterization of a two-good economic model, consumption good and capital good, enables straightforward resolution of various issues that have vexed the long Cambridge capital controversy, including the existence of single quantities for both capital quantity and capital value...

We develope a growth accounting method using the whole neoclassical growth model. We obtain three primary findings from our analysis of the U.S. economy during 1954--2017. First, the efficiency wedges in the entire period accurately account for the evolution of U.S. productivity and labor share....

Los modelos estándar de la teoría del crecimiento privilegian el papel del ahorro como explicación central del proceso de acumulación. La tradición keynesiana afirma que el ahorro es un simple residuo de las decisiones de inversión y que la acumulación deriva de la demanda efectiva. Esta...

Claims made in the course of the Cambridge capital controversy about the relationships among the quantity, value, and price of capital are necessarily scalar, as all of these are scalar values, even when made in respect of capital composed of heterogeneous commodities. However, the received...

For 70 years, the participants in the Cambridge capital controversy have been arguing about the wrong things––the technical aspects of capital and whether they can support the neoclassical theory of distribution beyond the case of the corn model, a single homogeneous good as both input and...
