Taxes and subsidies. Taxes are something that can
increase the price paid by the buyers and lower the prices received by the
sellers. So when the taxes decrease the quantity produced, it leads to
underproduction. Taxes can be incidence with the elastisity if the demand and
the supply when the division between buyers and sellers depends on the
elasticities of demand and supply.
Subsidies are a payment that the government give to
the producer which can decrease the prices paid by buyers and increase the
prices received by the sellers. Subsidies can lead to overproduction when they
increase the quantity produced.
Externalities. An externality is a cost or a benefir
that effects someone other than the seller or buyer. It can become
overproduction when the external cost arises and it become underproductionwhen
the external benefit arises.
A public good is a good or service that is consume
simultaneously by everyobe even if they do not pay for it. A market would be
underproduce national defense because it is in each person’s interest to free
ride on everyone else and avoid paying for the good that has been shared. A
common resource is owned by no one buy it is available to used by everyone. It
can be overused when in everyone’s self interest to ignore the costs they
impose on others when they decide how much common the resources to use.
Monopoly become one of the obtacles because it is a
firm that provides a good or service. It becomes underproduction when a
monopoly produces too little and charges too high to achive its goals.
A price ceiling is a charge that the government give
to the producer to make the price higher from the specified level. When a price
ceiling is set above the equilibrium it has no effect and the market works in
efficient way. But when the price ceiling is set below the equilibrium, it has
a powerful effect. A price ceiling can cause a black market where is an illegal
market that operatees alongside a legal market in which a price ceiling or
other restriction has been imposed.
According
to Fintan Ng that local prices are expected to remain
stable in August even as food prices soared abroad in the wake of a severe
draught hitting parts of the United States and Europe alongside rising energy
prices that can make subsidies and
price caps continued to mask inflationary pressure in the country, which had
experienced a drop in its consumer price index (CPI) since the beginning of the
year and they also expected
Bank Negara
to keep the key policy rate at 3% for the rest of the year as concerns over
growth outweighed inflation expectations.
The food
price increase because of the occurrence of inflation and the amount of money
in circulation. The occurrence of inflation in which is increase or rise in the
price of goods or services in a given period. Usually this happens during the
period with respect to the moment or event such as Hari Raya and Christmas.
For the
amount of money in circulation, this is because the earlier consumptive of the
citizen that makes them withdraw their funds that already been deposited for a
long time. And with those funds held over sometime makes people
"confused" to use it. Because it is simultaneously
make a certain item for the shoppers to assault it. Consequently,
according to the economic laws, as more and more requests then the price will
rise. If a stock available, it will rise under control and at a reasonable
range, if it is not then the price will increase dramatically even sometimes it
will become effects in the social events.
When the
food price is perfectly inelastic demand, the buyers pay the entire tax such as
the service tax in the restaurants and when it is perfectly elastic demand, the
sellers pay the entire tax. The more inelastic the demand, the larger is the
buyer’s share of the tax. But if there is no tax, the marginal cost of the food
is equal to the marginal social cost and that makes the market become efficient
but not for the production subsidies because at the quantity of food produced,
the marginal social benefit is equal to the market price which has fallen so
the production subsidies become inefficient and overproduction.
If the
marginal social benefit of the food is exceed the marginal social cost, so the
tax is inefficient because the tax revenue takes part in the total surplus and
the quantity of the food become decreased. So the marginal social benefit of
the food has increased or exceeded that make the production subsidies become
inefficient and over production. The production subsidies are overproduction in
the two situations above that make a market failure to the food, and the price
also increase higher than the original price before the subsidies happen to
them and the price expectations of inflation will also become a concern for the
rest of the year.
