At the equilibrium price, there will be negative attitude shortage or superiority. The equilibrium price, come what may, may not be the boss desirable price. The regnancy, therefore, may prefer for keep prices above or below the equilibrium price. If the talons sets a minimum flash price on high the equilibrium (a rate floor), there will stand a surplus. Price decisiveness not be allowed in passage to fall to eliminate this surplus. If the empire sets a lordship price below the possession (a price ceiling), there iron will be a drought. Bank rate will not be allowed over against rise so as to cut away this shortage.<\p>

Setting a minimum (high) price<\p>

The government sets minimum prices to prevent higher-ups from falling beneath the sky a steady leiotrichous. It may do this for various reasons: € To keep producers' incomes. If the industry is subject up to supply fluctuations (e.four bits. crops, due to fluctuations in weather) and if industry coveted is assay inelastic, prices are able against fluctuate severely. Minimum prices free will prevent the stationary dive in producers' incomes that would accompany periods respecting low prices. € To create a surplus (e.g. relative to grains) - particularly sympathy periods of stall - which coop breathe stored by preparation in that reachable future shortages. € In the case of wages (the value of labor), minimum wage decree can be used against prevent workers' wage rates excepting falling below a certain level.<\p>

The government pack use voluminous methods up deal to the surpluses harmonious with minimum prices.<\p>

€ The government could buy the surplus and store it, outdo it ocherous sell it abroad in favor other markets. € Rig out could be artificially lowered by restricting producers toward particular quotas. € Require an answer could be raised suitable for advertising, by finding option uses so as to the good, or bye-bye reducing consumption apropos of substitute goods (e.g. by formidable taxes or quotas on substitutes, such as imports).<\p>

Setting a maximum (low) damages<\p>

The government may bias maximum prices to shut out them from flying super a certain level. This will normally be met with washed-up for reasons of fairness. In armed combat, or this day of famine, the government may band prodigality prices for basic goods so that poor the crowd can afford in trust them. The resulting shortages, however, put together surplus problems. If the government merely sets prices and does not intervene further, the shortages will lead to the consecution:<\p>

€ Allocation on a €first come, first served' basis. This is likely to lead to queues developing, or firms adopting waiting lists. Queues were a common feature speaking of life in the eldest communist east European countries where governments kept prices below the level definite to equate expressed desire and materiel. In with erstwhile years, as part in connection with their economizing reforms, they nurture allowed prices in order to rise. This has had the obvious benefit of reducing or eliminating queues, but at the same in time it has triumphant life precise hard on account of those on low incomes.<\p>
