The fixing of the price of an item above or below the equilibrium price is most likely to take place in a centrally planned economy. In this type of economy, the government sets prices for goods and services, which can lead to price controls and price ceilings or floors. This can result in prices being set either above or below the market equilibrium price, causing either surpluses or shortages of goods and services. In contrast, a free market economy relies on supply and demand to determine prices, and prices tend to gravitate towards the equilibrium price. In a mixed economy, both government intervention and market forces influence prices. Developed economies can have a variety of economic systems, including centrally planned, free market, and mixed economies, so it is not necessarily true that fixing prices above or below equilibrium is more likely to occur in a developed economy.
