The New York supermarket

Jaume Collboni has returned from New York with an idea under his arm. After meeting with Mayor Mamdani, he announced that Barcelona will have a network of affordable shops. The concern is easy to understand: in five years, the purchase of food has become nearly 30% more expensive, and for many families this item already weighs too much on the family budget. The proposal also has a certain glamour: it has been presented as a "genuinely New York experience". But what does it exactly mean to make shopping more affordable?It may be difficult for us to fill the fridge for different reasons. Perhaps in the neighborhood we do not have enough supply of fresh produce. Or perhaps we have supermarkets and shops within reach, but we cannot afford their prices. In one case, there is a lack of supply; in the other, purchasing power: having a store downstairs is useless if we cannot pay for it. Both hinder access to adequate nutrition, but they are not the same problem nor do they require the same response.The City Council's pilot project will begin in La Marina del Prat Vermell, a growing neighborhood where the commercial offer is still limited. Bringing fresh produce there responds to the first of the problems and makes sense. But the project wants to go further: it not only promises proximity, but also affordable prices. And here begins the most interesting question: what will make them so? Because lowering the price has a cost: someone has to assume it, be it the City Council, the manager, the suppliers, or a combination of all three.There is no single way to lower the cost of groceries. New York is planning five municipal supermarkets: the city covers part of the costs and requires the savings to be passed on to prices, with a discount for everyone who shops there. Istanbul, on the other hand, has for decades combined a public network of food at low prices with aid directed at families with fewer resources. In the first case, public support makes the same basket cheaper regardless of who is doing the shopping; in the second, part of the effort is concentrated on those with lower income. Each formula allocates public resources differently and does not necessarily benefit the same families.Barcelona, furthermore, does not start from zero. It has a network of municipal markets, farmers' markets, and consumer cooperatives, as well as experience with aid such as prepaid cards. It already has, therefore, instruments to act both on supply and on the purchasing power of families. The question is whether it is necessary to create a new structure or if part of the objective can be achieved by reinforcing, connecting, or reorienting those that already exist. In Marina itself, in fact, the City Council was already working to promote local commerce before the trip to New York. Looking at what other cities are doing can be useful, but the question is not where we import the idea from, but who we want to reach, with what instrument, and what problem we want to solve.
