INTRODUCTION
In this presentation, we have highlighted the effect of price
flooring and price ceiling on agriculture and petroleum sector.
That whats effects occur on industry.
This presentation consist bit introduction of price flooring
and ceiling, then some related application alongwith effects
indications.
Price Ceiling and Price Flooring



These are usually enacted when policymakers believe
the market price is unfair to buyers or sellers.
The government can enact



Price ceilings, and
Price floors.


Price ceilings that involve a maximum
price below the market price create five
important effects on industry.

When prices are held below the market price shortages
are created.

The shortage = difference between the Qd and the Qs at
the controlled price.
The lower the controlled price relative to the market
equilibrium price, the larger the shortage.

At the controlled price, sellers have more

In a free market, this would be an opportunity to
profit by raising prices.
But when prices are controlled, sellers cannot.
Sellers respond to this problem in two ways:

Price controls that create shortages
lead to bribery and wasteful lines.






Shortages: not all buyers will be able to
purchase the good.
Normally, buyers would compete with
each other by offering a higher price.
If price is not allowed to rise, buyers must
compete in other ways.
Industry will not supply the best and result will
be:





How I Can Supply you Petrol at low Profit margin.


Dead-weight Loss is the total of lost
consumer and producer surplus when all
mutually profitable gains from trade are
not exploited.



Price ceilings create a dead-weight loss by
forcing Qs below the market Q.


Buyers and sellers would both benefit from trade at a
higher price, but cannot since it is illegal for price to
rise.
4.







Price controls reduce the gains from trade.

Price ceilings set below the market price cause Qs to be
less than the market Q.
When Q is below the equilibrium market Q, consumers
value the good more than the cost of its production.
This represents a gain from trade that would be
exploited (if the market were free).

Price controls distort signals and eliminate
incentives-- leading to a misallocation of
resources.






Consumers who value a good most are prevented
from signaling their preference (by offering sellers a
higher price.)
So producers have no incentive to supply the good to
the “right” people first.
As a result, goods are misallocated.
Price floor: a minimum price allowed by law.


If the government sets a price floor for butter above the
equilibrium market price, what will be the effect?
a)Farmers will produce less butter and consumers will
purchase more, resulting in a shortage of butter.
b)The supply of butter will increase and the demand will
decrease.
c)Farmers will produce more butter and consumers will
purchase less, resulting in a surplus of butter.
d)The equilibrium price will rise to the price floor.

So, buyers gain
So, sellers gain too

The total gain = the total subsidy
Which side gains how much depends on the
price elasticities of demand and supply



Higher quality raises costs and reduces seller profit.
Buyers get higher quality, but would prefer a lower price.
Price floors encourage sellers to waste resources:

Editor's Notes

  • #7 Instructor Notes: Figure 6.1: Price Ceilings Create Shortages At the controlled price, the quantity demanded exceeds the quantity supplied, creating a shortage. It should be noted that price is not allowed to rise to eliminate the shortage as would be the case in a free market.
  • #8 Instructor Notes:
  • #11 Instructor Notes:
  • #12 Instructor Notes: Figure 6.2: Price Ceilings Create Wasteful Lines At Qsupplied the willingness to pay is greater than the controlled price. The difference between what buyers are willing to pay and what sellers can charge encourages buyers to line up to buy the good. Buyers will lineup until the total price of the good, the out-of-pocket price plus the time cost, increases to the willingness to pay. Time spent waiting in line is wasted time. The total value of the wasted time is given by the time cost per unit multiplied by the quantity bought.
  • #13 Instructor Notes:
  • #14 Instructor Notes: It may be necessary to remind students of opportunity costs here. Wages are a good estimate of the opportunity cost of someone’s time.

Although mutually profitable, these trades are illegal. If all mutually profitable trades were legal, the gains from trade would increase by the green plus blue triangles. The lost gains from trade represent a dead-weight loss.
