We consider nonparametric identification and estimation in a nonseparable model where a continuous regressor of interest is a known, deterministic, but kinked function of an observed assignment variable. This design arises in many institutional settings where a policy variable (such as weekly...

Central to the welfare analysis of income transfer programs is the deadweight loss associated with possible reforms. To aid analytical tractability, its measurement typically requires specifying a simplified model of behavior. We employ a complementary "decomposition" approach that compares the...

We document that an increasing fraction of jobs in the U.S. labor market explicitly pay workers for their performance using bonuses, commissions, or piece-rates. We find that compensation in performance-pay jobs is more closely tied to both observed (by the econometrician) and unobserved...

We examine the evolution of the returns to human capital in Canada over the period 1980-2005. Our main finding is that returns to education increased substantially for Canadian men, contrary to conclusions reached previously. Most of this rise took place in the early 1980s and since 1995....

This paper looks at the evolution of incomes at the top of the distribution in Canada. Master files of the Canadian Census are used to study the composition of top income earners between 1981 and 2011. Our main finding is that, as in the United States, executives and individuals working in the...

This paper argues that changes in the returns to occupational tasks have contributed to changes in the wage distribution over the last three decades. Using Current Population Survey (CPS) data, we first show that the 1990s polarization of wages is explained by changes in wage setting between and...

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 proposes an empirical approach to decompose the distributional effects of minimum wages into effects for workers moving out of employment, workers moving into employment, and workers continuing in employment. We estimate the effects of the minimum wage on the hazard rate for wages,...
