After the supermarket, head to a shoe store. There, the investigator not only notes the prices, but also the composition. As inflation increases the price of raw materials, manufacturers can reduce their costs: “They use less cotton, they use another fiber that doesn’t cost much, and they stay at the same price”, Christian sometimes observes. His day continues with checking the price of a restaurant’s menu, which has not changed.
In addition to stores and restaurants, investigators find “tuition fees for private schools, canteens, museums…”. Christian can thus register up to 200 prices per day. And in addition to all these figures recorded one by one, INSEE receives 80 million receipts daily, sent directly from supermarkets.
A multitude of factors are driving the rise in prices, explains Sébastien Faivre, head of the “Consumer Prices” division at INSEE: “The cost of raw materials which is increasing, wage costs which are increasing with the increase in the minimum wage, transport costs, too, which are sometimes very significant, and then energy costs.”
