We develop a theory of commodity taxation featuring imperfect competition along with love-of-variety preferences and endogenous firm entry and exit, and we derive new formulas for the efficiency and pass-through of specific and ad valorem taxes. These formulas unify existing canonical ones and...

This paper studies commodity taxation in a model featuring heterogeneous consumers, imperfect competition, and tax salience. We derive new formulas for the incidence and marginal excess burden of commodity taxation highlighting interactions between tax salience and market structure. We estimate...

We study how changes to the informativeness of signals in Bayesian games and single-agent decision problems affect the distribution of equilibrium actions. Focusing on supermodular environments, we provide conditions under which a more precise private signal for one agent leads to an...

We study how information affects equilibria and welfare in games. For an agent, more precise information about an unknown state of the world leads to a mean-preserving spread of beliefs. We provide necessary and sufficient conditions to obtain either a non-increasing mean or a...

The disproportionate impact of children on women's earnings constitutes the primary factor contributing to persistent gender inequality in many countries. This paper examines the multigenerational impact of children and whether the public provision of formal childcare lessens the earnings and...

Intergenerational mobility has decreased over time for the cohorts of children born between the 1960s and the 1980s in Canada. At the same time, returns to education have gone up. Both factors have contributed to exacerbating income gaps between children of parents with and without secondary...

This paper uses Census microdata linked with tax records to quantify the contribution of career choices - occupations and fields of study - to intergenerational income mobility. We document substantial segregation into occupations by parental income. Yet, the occupations children pursue explain...

We study the effects of the unionization of faculty at Canadian universities from 1970-2022 using an event-study design. Using administrative data which covers the full universe of faculty salaries, we find strong evidence that unionization leads to both average salary gains and compression of...

We derive a sufficient statistics optimal income tax formula in a general model that incorporates unemployment and endogenous wages, to study the shape of the tax and transfer system at the bottom of the income distribution. The sufficient statistics are the macro employment response to taxation...
