Over the last decades, productivity in the tradable sector rose substantially, while in the non-tradable sector, output per worker has remained the same, despite a similar increase in human capital in both sectors. This paper emphasizes that duality in higher education as well as heterogeneous...

This paper shows that countries with high levels of "elitism" in higher-education are the countries displaying high levels of inequality. In other words, a higher level of "elitism", i.e., large gap in quality of universities, and tight selection in top universities leads to a wider gap in wages...

We construct a multi-layer model of skills, occupations, and sectors. Technological progress among middle-skill occupations raises the employment shares and relative wages of lower- and higher-skill occupations (horizontal polarization), and those of managers over workers (vertical...

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...

We construct and estimate a unified model combining three of the main sources of cross-country income disparities: differences in factor endowments, barriers to technology adoption and the inappropriateness of frontier technologies to local conditions. The key components are different types of...

Sectoral data features (i) changing relative expenditures of different sectors, (ii) non-constancy in relative prices and (iii) long-run trends in relative TFP growth rates across sectors. We provide a tractable theory of industry directed technical change, which is able to reconcile these...

The demographic transition that swept the world in the past 140 years has been identified as one of the prime forces in the transition from stagnation to growth. The unprecedented increase in population growth during the early stages of industrialization was ultimately reversed. The rise in the...

This research argues that variations in the interplay between cultural assimilation and cultural diffusion have played a significant role in giving rise to differential patterns of economic development across the globe. Societies that were geographically less vulnerable to cultural diffusion,...

This research explores the effect of industrialization on the process of development. In contrast to conventional wisdom that views industrial development as a catalyst for economic growth, the study establishes that while the adoption of industrial technology was conducive to economic...

The research explores the effect of industrialization on human capital formation. Exploiting exogenous regional variations in the adoption of steam engines across France, the study establishes that in contrast to conventional wisdom that views early industrialization as a predominantly...
