Thank you very much.
Thanks for inviting me to participate today. I understand that this committee is studying inflation in the food supply chain and that there is particular concern about possible overpricing and excess profits for large grocery retailers.
I'm not an agricultural economist and have not previously studied pricing in the agribusiness sector, however, I have done research on overpricing, excess profits, collusion and other related issues. I've served as an expert witness in these areas on multiple occasions and have estimated the extent of overpricing and excess profits in many of these cases.
I've done a quick review of food pricing issues in Canada recently, so I hope I'll be able to contribute something to the committee's deliberations, but I can't make any promises.
According to Statistics Canada, overall inflation, as measured by the consumer price index, was about 7% in 2022, the highest level in 40 years. Food purchased from stores was by about 10%. Therefore, food price inflation exceeded the general price inflation by about three percentage points. I'll call that the food inflation premium. I've posed a set of questions to myself and I'll provide answers to those questions.
First of all, background. What do we mean by overpricing and excess profits? People use those terms in different ways, but like most economists, what I mean by overpricing is pricing over and above what we would expect in an undistorted and reasonably competitive situation for the industry in question. Excess profits are profits that arise from overpricing.
What are the causes of this food inflation premium? Among those causal factors, how important is overpricing by grocery retailers? There are several obvious factors in addition to overpricing by retailers. One is the war in Ukraine, which reduced supply and increased prices for grains and other products. Another is climate events, such as droughts in parts of Canada, floods and droughts in the rest of the world. This is not about climate change but it seems beyond just scientific dispute that these increasingly severe weather events are due, at least in part, to climate change. I'd also mention the continuing supply chain effects of the COVID-19 pandemic, although they are winding down, and specific events, such as the bird flu, which caused a crisis to arise in 2022.
Most of these effects are not specific to Canada and therefore, should also affect other countries. I took a look at other countries and, in fact, Canada's food price inflation was less than the OECD average in 2022 and, more importantly, the food price premium was less in Canada than the OECD average. Taking into account all these factors, there's actually not much left to be explained by domestic overpricing.
Is there evidence of collusion or any type of other anti-competitive practice in the grocery sector? Not really. In 2017 we had the bread price collusion case. We would, of course, expect the response to that would be that supermarket chains would be very cautious about engaging in further collusion and I think they have been. Now, I believe that the Competition Bureau is looking at the industry, but I'm not aware of anything that's come up in recent years.
What about profitability? Has it risen in the grocery sector? It's hard to be definitive, but it looks as though it has risen somewhat over the COVID-19 period. I checked out stock prices; they've risen somewhat relative to the TSX—not a lot, but somewhat. That's exactly what I would have expected as a result of the pandemic because the pandemic created conditions favourable to grocery store profits, shifts in demand towards grocery stores away from restaurants and shortages making it possible to raise prices and premiums. So it's not a surprise there.
Does this mean that price increases in the grocery sector are "profit driven?" Of course, they are. I would say that almost all price changes in the market economy are profit driven. Companies are in business to make profits so, of course, they adjust their prices accordingly. And that's a good thing because the incentive to earn profits generates social and economic benefits more effectively than any other system. As Adam Smith said “It is not from the benevolence of the butcher, the brewer, or the baker, that we expect our dinner, but from their regard to their own interest.”
Increases in prices act as a signal. Often, temporary high profits can be earned, but that acts as a signal to potential competitors to enter or to expand, and to consumers to waste less. I would point out that during the COVID-19 period there was still far too much food waste in Canada. In any case, this is precisely the response that is needed—more supply and less demand. Imposing price controls or increased profit taxes would probably provide exactly the wrong incentives and make problems worse, not better, as we know from other situations where we tried to apply such remedies.
However, that said, Adam Smith also warned us to be wary of collusion and anti-competitive practices, pointing out that market power could be detrimental to the public interest.
Is there a structural problem in the grocery sector due to insufficient competition? Well, there could be. The regional sector has a pretty high concentration with three companies having about a 60% market share. The retailers have a lot of market power relative to small suppliers. There are also large suppliers—
