Government Failure
Government failure happens when government intervention in a market leads to a net welfare loss. Put simply, when government intervention makes the allocation of resources even worse than before.
Causes of Government Failure
1.Distortion of Price Mechanism
Government intervention can distort price signals, which weakens the price mechanism. When prices cannot adjust freely, markets may not clear and shortages or surpluses can appear.
This can lead to:
Surpluses from minimum prices
Shortages from maximum prices
Maximum Prices
An example is a maximum price for petrol (a fuel price cap).
A maximum price P1 is set below the free market equilibrium price Pe in the diagram.
At P1, firms are less willing/able to supply, so quantity supplied falls to Q1, while consumers want more at the lower price, so quantity demanded rises to Q2. This creates excess demand (a shortage) of Q2 − Q1, as shown on the diagram.
In this case, “excess demand” could mean queues at petrol stations, rationing per customer, and some consumers being unable to buy fuel even though they’re willing to pay P1. Without the maximum price, the price mechanism would push prices up toward Pe, which would reduce quantity demanded and increase quantity supplied, helping the market move back toward Qe. However, the maximum price prevents the price mechanism from functioning to clear the shortage.
Minimum Prices
If a minimum price is set above the equilibrium price, supply becomes greater than demand. This creates excess supply because the price cannot fall to remove the surplus.
For example, agricultural minimum prices can lead to wasted food when surplus output cannot be sold - as seen in the EU’s Common Agricultural Policy (CAP) “wine lakes and butter mountains”
2.Unintended Consequences
Examples
The British government in colonial Delhi wanted to reduce dangerous cobras, so they paid people for every dead snake handed in.
Instead of reducing numbers, locals started breeding cobras to earn money.
When the bounty was cancelled, breeders released the snakes, leaving the city with more cobras than before
Unintended Effects of Maximum Prices
Rent Controls
Rent controls (maximum price on rent) can reduce landlords’ incentives to maintain properties. This means the landlord's incentive to maintain and improve properties falls , leading to falling quality e.g damp/mould. As a result, although the policy is meant to improve access to housing, it can worsen quality and reduce availability therefore meaning the government has intervened in the market and made the allocation of resources worse than before thus representing govt failure .
3.Administrative Costs
These administrative costs can be large and get out of control thus meaning they can exceed the benefit of government intervention thus leading to government failure .
Example: UK Dog Licence (Scrapped 1987)
For over a century, dog owners in Great Britain had to buy a dog licence.
The aim: raise revenue
The problem: by the 1980s, the fee was still stuck at 37p
Why it backfired: issuing each licence cost the govt around £4 in admin (processing, paper, postage), but it only brought in 37p.
That meant the government was losing around £3.60 per licence . So a tax which was meant to raise revenue became a policy that burnt money .
4.Information Gaps
Governments do not have perfect information when setting policy. This makes it difficult to choose the correct level of tax, subsidy, or regulation.
This may cause:
Taxes set too high or too low
Subsidies misjudged
Regulation too strict or too weak
Some Extra Real World Examples
UK Energy Market
Ofgem raised the price cap by 53%. Some pensioners used buses to stay warm due to higher heating costs.
British Gas made £948m profit during this period.
NHS IT Programme
Over £10bn was spent on the programme. It was eventually abandoned and did not work properly.
