What Explains the Rising Profit Share in Canada?

The distribution of the gains of economic growth among workers and corporations has evolved over time. While an extensive body of literature has studied the fall in the share of labour income in the gross domestic product (GDP), less attention has been paid to the development of the components of its counterpart, the capital share. In the system of National Accounts, the capital share of income can be broken down into net operating surplus and net mixed income (which includes corporate profits before taxes, net interest paid, net other payments and inventory valuation adjustment, and net mixed income) and capital consumption allowances (CCA). This report contributes to the discussion on the rising capital share by studying the evolution of the Canadian corporate profit share in the past three decades using both financial and national accounts data. We analyze trends at the aggregate and sectoral level and compare the aggregate trends to those in the United States during the same period. We also provide an overview of the structural factors affecting the corporate profit share in Canada. According to national accounts data, the corporate profit share before tax in Canada rose 3.8 percentage points between the 1961-1999 and 2000-2017 periods, an increment that significantly enhanced the surge in the capital share of income. Similarly, the financial corporate profit share of income increased by 7.2 percentage points between 1997 and 2017. This development was widespread, with the profit share increasing in all sectors except mining, quarrying and oil, and gas extraction. It was also concentrated. We find that the financial sector, which accounts for less than one tenth of GDP, was responsible for 33 per cent of the increase in the corporate profit share. Complete time series of the profits data used in this report can be found in a profits database developed as part of this research project.
