Real World Examples (RWE's) Price Floors
Price floors in the real world
A price floor is a minimum price set by the government for a particular good or service, above the equilibrium price.
In this case, we look at minimum wages as an example of a price floor. The UK sets a legally binding minimum wage to protect workers against unduly low wages. This is especially important in times of rising prices, like the UK has experienced recently (see blue line graph to the right showing: Inflation rate for the Consumer Price Index (CPI) in the United Kingdom from January 1989 to February 2024)
Minimum wages are constantly revised to make sure they offer adequate remuneration (pay) per period time for workers. This policy aims to reduce poverty and income inequality, encouraging fair pay for work done. A minimum wage is even more relevant considering the recent cost of living crisis in mind! Because of this recent inflation spike, low income, fixed income and retirees suffered a disproportionate hit to their purchasing power and ability to buy goods and services.
For this reason, the UK government revised the legally binding minimum wage upwards to £11.44 per hour (see wages table to the right).
Whilst an increase in minimum wage is always celebrated by workers, it is rarely celebrated by businesses and usually agreed to be destructive to overall employment!
Here is why.
For workers: the increase in minimum wage increases affordability of goods and services. This is a positive outcome as wages increase by £1/hour (before tax)
For businesses: don’t forget that the demand curve represents, ‘demand for labour’! Referring to the diagram, as the NMW increases (price floor) demand for labour falls from 30 million workers to 28 million workers, creating a yellow section of excess supply of labour!
The market: Increase in NMW reduces demand for labour, causing unemployment (from 30m workers at equilibrium to 28m after the new NMW is implemented), which is destructive as one of the major objectives of government.
Black market: As business costs increase with rising NMW’s, there is an incentive for businesses to hire workers illegally and pay them in cash or ‘under the table’. This incentive is more likely as the supply of undocumented labour rises in the UK, which is currently estimated to be between 0.5 and 1m people in 2024.
The conclusion is that, whilst those who retain their jobs receive a pay rise, but the net result is greater joblessness! The effectiveness of a price floor in this case needs some serious discussion to address the unintended consequences that follow!
