Skill-Biased Technical Change is one of the most prominent explanations for the rise in wage inequality in the United States over the last decades. However, the explanation is challenged for several reasons. In this paper, I propose an alternative type of technical change, where new technologies...

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...

Job polarization the rise in employment shares of high and low skill jobs at the expense of middle skill jobs occurred in the US not just recently, but also in the late nineteenth and early twentieth centuries. We argue that in each case polarization resulted from increased automation, and...

During the last two decades, the labour demand structure in Germany has experienced a decrease in the demand for the low skilled. Possible explanations for this trend are investigated in this study for West Germany (1994- 1997) using a unique linked employer-employee panel data set for Germany....

This paper studies a model of the distribution of income under bounded needs. Utility derived from any given good reaches a bliss point at a finite consumption level of that good. On the other hand, introducing new varieties always increases utility. It is assumed that each variety is owned by a...

We analyze some macroeconomic implications that follow from the fact that people tend to consume higher-quality goods as their incomes rise. The model involves two sectors: one producing a homogeneous good and the other producing a product with variable levels of quality. Both sectors use...

The purpose of this paper is to investigate the mechanisms underlying the relationship between automation and labor market polarization. To do so, we build an agent-based model (ABM) in which workers, heterogeneous in nature and level of skills, interact endogenously on a decentralized labor...

Technical change that extends market scale can generate winner-take-all dynamics, with large income growth among top earners. I test this "superstar model" in the entertainer labor market, where the historic rollout of television creates a natural experiment in scale-related technological...

The US skill premium and college enrollment have increased substantially over the past few decades. In addition, while low-wage earners worked more than highwage earners in 1970, the opposite was true in 2000. We show that a parsimonious neoclassical model featuring skill-biased technical...
