We estimate the causal effects of a pandemic-era wage subsidy program in Canada on job losses and business closures. Our estimates use administrative microdata and a regression discontinuity strategy to estimate the effects of marginal changes in the wage subsidy rate. The estimated net wage...

Conventional wisdom has it that proportional representation leads to more coalition governments and so to greater government spending, especially in redistributive categories favoured by special-interest groups. In contrast, we show in a theoretical model that first-past-the-post systems of...

Investors frequently hold equity in tax-exempt savings vehicles such as pension plans, despite the prediction of the standard model that they hold only bonds. We provide a new explanation for this empirical puzzle based on differences between pensions and taxable assets in the tax treatment of...

Some governments have recently called for international accords restricting the use of preferential taxes targeted to attract mobile tax bases from abroad. Are such agreements likely to discourage tax competition or conversely cause it to spread? We study a general model of competition for...

We study corporate income tax competition when firms operating in multiple jurisdictions can shift income using financial planning strategies. Several such strategies, particularly intra-corporate lending, appear to be actively pursued by companies to reduce subnational corporate taxes in...

This paper shows how a popular system of federal revenue equalization grants can limit tax competition among subnational governments, correct fiscal externalities, and increase government spending. Remarkably, an equalization grant can implement efficient policy choices by regional governments,...

This paper investigates the effects of lobbying by corporations when investments are irreversible and government cannot commit to tax policies. We show that industries which rely more heavily on sunk capital lobby more vigorously and are generally more successful in obtaining tax breaks. Thus...

A simple theory suggests that a common form of federal horizontal equalization grants shouldcause subnational governments to levy higher tax rates, distorting local tax bases and soincreasing federal transfers. To test this, I examine Canadian provincial tax policies in the1972-2002 period....
