In this chapter we inspect economic mechanisms through which technological progress shapes the degree of inequality among workers in the labor market. A key focus is on the rise of U.S. wage inequality over the past 30 years. However, we also pay attention to how Europe did not experience...

The notion of skilled-biased technological change is often held responsible for the recent behavior of the U.S. skill premium, or the ratio between the wages of skilled and unskilled labor. This paper develops a framework for understanding this notion in terms of observable variables and uses...

This paper provides an introduction to the special issue of the Review of Economic Dynamics on "Cross Sectional Facts for Macroeconomists''. The issue documents, for nine countries, the level and the evolution, over time and over the life cycle, of several dimensions of economic inequality,...

We conduct a systematic empirical study of cross-sectional inequality in the United States, integrating data from the Current Population Survey, the Panel Study of Income Dynamics, the Consumer Expenditure Survey, and the Survey of Consumer Finances. In order to understand how different...

This paper studies consumption and labor supply in a model where agents have partial insurance and face risk and initial heterogeneity in wages and preferences. Equilibrium allocations and variances and covariances of wages, hours and consumption are solved for analytically. We prove that all...

In recent decades, the US wage structure has been transformed by a rising college premium, a narrowing gender gap, and increasing persistent and transitory residual wage dispersion. This paper explores the implications of these changes for cross-sectional inequality in hours worked, earnings and...

We address this question in a heterogeneous-agent incomplete-markets model featuring exogenous idiosyncratic risk, endogenous skill investment, and flexible labor supply. The tax and transfer schedule is restricted to be log-linear in income, a good description of the US system. Rising...

The Global Repository of Income Dynamics (GRID) is a new open-access, cross- country database that contains a wide range of micro statistics on income inequality, dynamics, and mobility. It has four key characteristics: it is built on micro panel data drawn from administrative records; it fully...

Heathcote et al. (2010) conducted an empirical analysis of several dimensions of inequality in the United States over the years 1967-2006, using publicly-available survey data. This paper expands the analysis, and extends it to 2021. We find that since the early 2000s, the college wage premium...

We argue that a 2-agent version of the standard New Keynesian model--where a "worker" receives only labor income and a "capitalist" only profit income-- offers insights about how income inequality affects the monetary transmission mechanism. Under rigid prices, monetary policy affects the...
