Thank you, Mr. Blaikie.
Yes, I accept the first two links in that chain that you mapped out at the beginning. We do need higher productivity. Productivity is a virtue, and we all want to be as efficient as we can.
Now, productivity on its own doesn't necessarily mean we benefit from it. There is often an assumption made—and I think Ben, to some extent, made that in his opening remarks—that higher productivity automatically means higher wages for Canadian workers, and that's absolutely not true.
It creates the space to pay higher wages without having any impact on profit margins, but whether the higher wages result or not depends on the institutions of the labour market that shape wage growth. There's no guarantee that higher productivity will lead to higher wages, but it creates some space. If we combine it with trade unions, collective bargaining and strong minimum wages, then we can translate higher productivity into higher wages.
I agree fully with Ben and others that higher investment in machinery, equipment and technology is one key feature of strong productivity growth over time. Canada's performance on machinery and equipment investment has been miserable since the turn of the century. In fact, since about the year 2000, the share of Canada's GDP that has gone into machinery and equipment investment by Canadian businesses has fallen roughly in half, from about 6% on average during the latter decades of the 20th century, to about 3% today.
That timing coincides perfectly with the reductions in corporate income taxes that were implemented first by then federal finance minister Paul Martin and echoed in many provinces by reductions in the provincial tax rate. I've done research that's been published in the Canadian Tax Journal and other outlets showing that there's no statistical correlation between reductions in across-the-board corporate income taxes and higher business investment.
What we need is more focused, tailored and contingent fiscal tools to try to elicit more business investment. Rather than just giving big wads of extra money back to the corporate sector with no strings attached, we're better off having targeted measures, such as an investment tax credit—that's an idea I support—where you have to pay to play, if you like, and the companies get the benefit only if in fact they invest.
The proactive measures by government to stimulate investment in targeted strategic areas, such as the made-in-Canada clean energy subsidies that I mentioned in my remarks, are also another approach. International comparisons have shown that investment by the public sector, in partnership with private business, targeted to particular projects—what my fellow student Mariana Mazzucato calls “mission-oriented innovation” programs—can have a more positive impact than no-strings-attached and across-the-board tax cuts.
More business investment is a good idea, but just dangling a bigger carrot in front of the corporate sector is not going to win that.
