This paper analyses the effects of disease and war on the accumulation of human and physical capital. We employ an overlapping-generations frame-work in which young adults, confronted with such hazards and motivated by old-age provision and altruism, make decisions about investments in schooling...

The elasticity of substitution between capital and labor (σ) is usually considered a "deep parameter". This paper shows, in contrast, that σ is affected by both globalization and technology, and that different intensities in these drivers have different consequences for the OECD and the...

Rapid technological progress in artificial intelligence (AI) has been predicted to lead to mass unemployment, rising inequality, and higher productivity growth through automation. In this paper we critically re-assess these predictions by (i) surveying the recent literature and (ii)...

In "The Race between Man and Machine: Implications of Technology for Growth, Factor Shares, and Employment," Acemoglu and Restrepo (2018b) combine the task-based model of the labor market with an endogenous growth model to model the economic consequences of artificial intelligence (AI). This...

Economists' two main theoretical approaches to understanding Artificial Intelligence (AI) impacts have been the task-approach to labor markets and endogenous growth theory. Therefore, the recent integration of the task-approach into an endogenous growth model by Acemoglu and Restrepo (AR) is a...

How do firms respond to technological advances that facilitate the automation of tasks? Which tasks will they automate, and what types of worker will be replaced as a result? We present a model that distinguishes between a task's engineering complexity and its training requirements. When two...

Electricity is a general purpose technology and the catalyst for the second industrial revolution. What was its impact on the structure of employment? We use U.S. Census data from 1910 to 1940 and measure electrification with the length of higher-voltage electricity lines. Instrumenting for...

Entrepreneurship in most advanced economies is in decline. This comes as a surprise: many scholars have expected an upsurge in entrepreneurship. What are the reasons for the decline? In this paper I first document the extent of the decline in terms of entrepreneurial entry rates; the share of...

After a number of AI-winters, AI is back with a boom. There are concerns that it will disrupt society. The immediate concern is whether labor can win a 'race against the robots' and the longer-term concern is whether an artificial general intelligence (super-intelligence) can be controlled. This...

This paper shows that African economies have generally not de-industrialized, that manufacturing growth is very possible, and moreover that the contribution of manufacturing in Africa has been underestimated. As far as the future is concerned, African countries will in differing degrees...
