Thank you, Mr. Chairman, for that question.
It's an intriguing measure to contemplate in the current circumstances, because when we look at financial market turmoil and economic turmoil, tax reform, especially sales tax reform, isn't obviously the first thing a lot of us would reach for. However, we're presented with a fascinating opportunity for change in Ontario. The Ontario government to this point, I think it would be fair to say, has not been roundly applauded for its economic management. Seizing the moment for change in Ontario would be a terrific thing. Here's why: retail sales taxes are dumb taxes because they stack up costs of business, they raise cost to consumers, they raise the cost of new business investment in plant equipment and processes and that slows down investment, slows down wage growth, and boosts the cost of our exports. So it harms our competitiveness in international markets.
The opportunity for reform, in particular value-added tax reform, the cost that businesses are forced to build into their price of products, is simply stripped out by way of the credit invoice system. That means there's a sharp reduction in the effective tax rate on your business investment, and that tends to drive growth in investment and then wages and productivity.
What happened in 1997 when the eastern provinces harmonized at a slightly lower rate than they were taxing before is just a terrific example. The prices of some things that hadn't been taxed before under the provincial tax went up. Other things stayed the same and some other prices went down. Overall the broad price level in the eastern provinces dropped by roughly the amount of the decline in the net tax rate. So the competitive markets delivered a very quick pass-through of the lower tax on consumer prices.
Even better was the boost to investment. You have to do some fancy footwork to strip out the economic growth that was already happening in the eastern economies. Oil and gas were taking off in the mid- to late 1990s. When you adjust for all that, you still find there is a pop in investment per capita of better than 10% post-reform. That's a huge shock. It's a long-lasting positive shock and it's been a tremendous boost to the provincial economies. It lowers costs for businesses because they only have one set of sales taxes to comply with. It lowers costs for governments too. So there are wins on all sides--wins for consumers, wins for business, wins for federal and provincial governments, and that's why we encourage reform. That's why I'm delighted and hopeful that Ontario's budget today will put forward a sales tax reform program.
