The paper reviews recent developments in the literature on wage inequality, with a particular focus on why inequality growth has been particularly concentrated in the top end of the wage distribution over the last 15 years. Several possible institutional and demand-side explanations are...

The paper presents descriptive evidence from quantile regressions and more "structural" estimates from a human capital model with heterogenous returns to show that most of the increase in wage inequality between 1973 and 2005 is due to a dramatic increase in the return to post-secondary...

This paper estimates employment equations based on the traditional labour demand model and modern efficient bargain theory using data drawn from wage contracts signed in the Canadian private unionized sector between 1978 and 1984. Contrary to the labour demand model predictions, the alternative...

This paper studies the determinants of real wage rates using data on Canadian labour contracts signed between 1978 and 1984. Its results are consistent with Dunlop's neglected (1944) hypothesis that real pay movements are shaped by product price changes (contrary to the predictions of implicit...

Over most of the 20th century successive generations of U.S. children had higher enrollment rates and rising levels of completed education. This trend reversed with the baby boom cohorts who attended school in the 1970s, and only resumed in the mid-1980s. Even today, the college entry rate of...

Although the college-high school wage gap for younger men has doubled over the past 30 years, the gap for older men has remained nearly constant. We argue that these shifts reflect changes in the relative supply of highly-educated workers across age groups. Cohorts born in the first half of the...

We examine the changing relationship between unionization and wage inequality in Canada and the United States. Our study is motivated by profound recent changes in the composition of the unionized workforce. Historically, union jobs were concentrated among low-skilled men in private sector...

This paper examines the role of spillover effects of minimum wages and threat effects of unionization in changes in wage inequality in the United States between 1979 and 2017. A distribution regression framework is introduced to estimate both types of spillover effects. Threat effects double the...

This chapter provides a comprehensive overview of decomposition methods that have been developed since the seminal work of Oaxaca and Blinder in the early 1970s. These methods are used to decompose the difference in a distributional statistic between two groups, or its change over time, into...

This paper provides an introduction and "user guide" to Regression Discontinuity (RD) designs for empirical researchers. It presents the basic theory behind the research design, details when RD is likely to be valid or invalid given economic incentives, explains why it is considered a...
