Interest rates have risen again. Inflation has not declined. Almost everything costs more right now, especially groceries. Meanwhile, in the wake of two major companies announcing temporary price freezes within hours of one another, Canada's competition bureau has announced its intention to study why grocery prices are so high, and if having more players in the market would lower them.Are higher prices a result of inflation, profiteering, or both? How can we tell, anyway? Did the price freezes spur this investigation, or was this something planned all along? And is raising interest rates to combat inflation really our best option? What else could we try if this doesn't work?GUEST: Jim Stanford, Economist and Director of the Centre for Future Work
