I discuss a dynamic version of the Zodrow-Miezskowski model, where world capital supply is not fixed. The time horizon of the welfare maximizing government is assumed to be infinite whereas the household sector is designed according to the two-period overlapping-generations model. Thus social...

Cross-country data reveal that the per capita incomes of the richest countries exceed those of the poorest countries by a factor of thirty-five. We formalize a model with embodied technical change in which newer, more productive vintages of capital coexist with older, less productive vintages. A...

The empirical literature on economic growth and development has moved from the study of proximate determinants to the analysis of ever deeper, more fundamental factors, rooted in long-term history. A growing body of new empirical work focuses on the measurement and estimation of the effects of...

This paper explores the implications of Unified Growth Theory for the origins of existing differences in income per capita across countries. The theory sheds light on three fundamental layers of comparative development. It identifies the factors that have governed the pace of the transition from...

An interview with Oded Galor on the development of unified growth theory.

Business cycle analysis, i.e. investigations into the more or less regular fluctuations in economic activity, emerged around the mid-nineteenth century. During Ragnar Frisch’s formative years as a young economist the field came to the centre of attention. Frisch was highly concerned about the...

In the Dasgupta-Heal-Solow-Stiglitz model of capital accumulation and resource depletion we show the following equivalence: If an efficient path has constant (gross and net of population growth) savings rates, then population growth must be quasi-arithmetic and the path is a maximin or a...

Using a neo-classical growth model, we analyse the real and nominal GDP per capita convergence of 21 emerging market economies (EMEs) of Central and Eastern Europe towards the EU15 average by 2050. We estimate the countries’ initial capital stocks and project future investment as a function of...

The sources of economic growth and development have been puzzling economists from the modern dawn of the profession. While the Solow-Swan neo-classical model dominated research on growth in the 1960s and 1970s, the 1980s saw the emergence of growth theories that disputed, largely on theoretical...

The debate on the ontological foundations of evolutionary economics has reached a stage where discussions of these foundations are increasingly leading to the conclusion that there is a need to move from considerations of the general principles of evolutionary theory to the development of...
