This paper estimates the elasticity of substitution between capital and skill using variation across U.S. counties in immigration-induced skill-mix changes between 1860 and 1930. We find that capital began as a q-complement for skilled and unskilled workers, and then dramatically increased its...

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...

There is a dearth of research on the impact of technological change on employment in the context of least developed countries (LDCs) embarking on globalization, which enhances the prospect of direct technological imports or embodied technological transfer. Using a sample of 1,940 enterprises...

This research applies a task-based approach to measure and interpret changes in the employment structure of the 168 largest US cities in the period 1990-2009. As a result of technological change some tasks can be placed at distance, while others require proximity. We construct a measure of task...

How will the emergence of ChatGPT and other forms of artificial intelligence (AI) affect the skill premium? To address this question, we propose a nested constant elasticity of substitution production function that distinguishes among three types of capital: traditional physical capital...

In a Walrasian labor market, the labor income share is constant under the assumptions of a Cobb-Douglas production function and perfect competition. Given the observed decline of the labor share in recent decades, this paper relaxes these assumptions, proposes a time-series calculation of the...

This paper discusses the occurrence of Skill-Enhancing Technology Import (SETI), namely the relationship between imports of embodied technology and widening skill-based employment differentials in a sample of low and middle income countries (LMICs). In doing so, this paper provides a direct...

While the skill-premium has been rising sharply in the US and the UK for 20 years, the Dutch skill-premium decreased for much of that period and only started to rise in the early 90s. In this paper, we investigate whether the Dutch skill-premium will rise in the next decades. To answer this...

Skill-biased technical change is usually interpreted in terms of the efficiency parameters of skilled and unskilled labor. This implies that the relative productivity of skilled workers changes proportionally in all tasks. In contrast, we argue that technical changes also affect the curvature of...

In this paper I argue that the manufacturing sector still has an important role to play in Africa's development. Despite failing to industrialize in the past, there may be a new window of opportunity. This is due to the convergence of what has been called "brilliant" new technologies associated...
