This paper characterizes optimal policies in the presence of tax evasion and undocumented workers. Equilibrium can be characterized as segmented or non-segmented, depending on whether domestic workers work exclusively in the formal sector (segmented) or also in the informal sector...

The Canadian federal tax reform of 1988 replaced a spousal tax exemption with a non-refundable tax credit. This reduced the "jointness" of the tax system: after the reform, secondary earners' effective "first dollar" marginal tax rates no longer depended on the marginal tax rates of their...

The goal of the paper is two-folds. First, I construct and estimate a dynamic structural occupational choice model at the three-digit classification level, in which different occupations involve different mix of tasks. Second, I conduct a counterfactual simulation using the estimated model, to...

Identifying the effect of differential taxation on portfolio allocation requires exogenous variation in marginal tax rates. Marginal tax rates vary with income, but income surely affects portfolio choice directly. In systems of individual taxation – like Canada’s – couples with the same...

According to Canadian taxfiler data, over the last thirty years there has been a surge in the income shares of the top 1%, top 0.1% and top 0.01% of income recipients, even with longitudinal smoothing by individual using three- or five-year moving averages. Top shares fell in 2008 and 2009, but...

I investigate the impact of the Canadian Federal tax reform of 1988 on the labour supply of lower income married women. The Canadian federal tax reform of 1988 replaced the spousal exemption with a nonrefundable tax credit. This reduced the dependence of a low income married woman’s effective...

Within the 65+ age group, the percentage of labour market income received by the top 1% of earners has increased from about 30% in 1982 to more than 60% in 2002. The trend is smooth, is roughly uniform across provinces and does not appear to have been accelerated by top marginal tax rate...

Contributions to tax-preferred savings accounts are typically constrained by a contribution limit. These limits influence contributions not just in periods in which they bind, but in other periods as well. I develop a simple life-cycle model in which consumers exhibit "use-it-or-lose-it"...

Federal tax reform in 1988 flattened the Canadian personal income tax schedule, changing the marginal tax rates for many individuals. Using methods similar to those applied by Auten and Carroll (1999) in the study of the effects of the 1986 U.S. Tax Reform Act, we estimate the responsiveness of...
