Recently the British food Industry has been facing volatile food prices specifically for bread and milk, given that demand for food is rising while supermarket wars are becoming tougher. Companies sometimes drop prices even below the cost of production, known as predatory prices, which is considered illegal in many economies. So you might be wondering how can supermarkets be losing that much profits by selling with such elevated costs? While prices of some foods are dropping scandalously, other are rising to cover up loses, causing misunderstandings over market prices and confusion for consumers.
The biggest concern is when analyzing low income level consumers, who strongly depend on inferior goods like bread, who now need to pay higher prices for these, while other superior goods which they cant afford in the first place, are having prices over the roofs in order for companies to balance profits. Overall i think this idea benefits the “B and A classes” middle and high income classes, who turnout to have daily trade offs between buying superior or inferior goods able to analyze prices and make choices. But others within the low income class have no choice but to accept higher prices for inferior goods given that these are their only choice.
