The government can only regulate prices for certain foodstuffs and that is only the upper limit or highest price, and the market will always determine the overall price, the rarer the goods are found and the demand is high, the market will automatically raise prices, and you will know that in countries with high levels of corruption and even their officials are involved in determining prices in the market because they are trying to make a profit.
What the government can do is only monitor prices in the market and when they have exceeded the normal limit, the government will act, but often they fail to carry out this function so that the prices of basic commodities continue to rise and sometimes they are rarely available on the market.
That's right, the government does regulate certain food prices and the market will determine depending on the demand for the item. If the item is scarce and demand increases of course the price of the item will continue to increase and this will be very difficult for the government to control. When government officials are in an area with a high level of corruption, it will be very difficult to find a stable price for an item, of course there are even some groups who hold back an item so that the price of the item increases and they can make a profit from the item.
