Factors that explain wage inequality

A look at factors that explain wage inequality – including classical economic theory and labour market imperfections. Readers Question: Idealized free market theory argues that it is automatic for each worker to receive just what he or she is worth; otherwise, an “underpaid” worker could just look elsewhere to bid a higher salary.  Could established …

Participation Rate

Definition of Participation Rate. The participation rate is the number of people working or actively seeking work as a % of the working population (16-65). The participation rate is similar to the concept of being ‘economically active’. If a person drops out of the labour market, they are considered economically inactive and no longer participating. …

Problems of free movement of labour

average-wage-rates

In a recent post, we looked at the advantages of free movement of labour. But, what about the problems which might arise from free movement of labour? Firstly, free movement of labour depends on the area in question. To make an easy contrast, initially, the EU was free movement of workers between 12 / 15 …

Does real wage inflation help the economy?

Real wage inflation means an increase in average earnings adjusted for inflation. See also: Real wages Rising real wages means an increase in living standards and greater purchasing power of consumers. In the past decade, many economies such as US and UK have witnessed stagnant real wage growth. A rise in real wages would be …

Labour shortages

labour-shortages

Labour shortages occur when employers struggle to fill labour vacancies because of insufficient labour applying for the jobs. Labour shortages can occur in geographical regions or in occupations with special requirements in terms of skill or function. Labour shortages can also be seasonal in industries like retail (Christmas) and agriculture (harvest time) Reasons for labour …

Monopsony Exploitation

monopsony
  • Monopsony occurs when there is one buyer and many sellers.
  • In the labour market, a monopsony occurs with one employer and many workers wanting to gain employment.
  • Arguably, monopsony power enables firms to ‘exploit’ workers by setting lower wages and employing fewer workers than in a competitive market.

To visualise monopsony power, we could think of a coal mining town in the nineteenth century. In these towns, the principal source of employment was a coal mine owner (or cotton mill owner). If workers couldn’t get employment in the coal mine, or cotton mill there were few other alternatives. Hence we can understand why workers in the Victorian era were often facing low wages and dreadful conditions.

In this case of monopsony power, the coal mine owner has the ability to be a wage setter. A monopsony can pay wages lower than in a competitive market.

monopsony

The marginal cost of employing extra workers increases at a faster rate than the average cost. Because if you increase the wage rate to attract more workers, you have to pay everyone a higher wage.

A monopsony maximises profits by employing a quantity of workers where MR = MC (Q2). This means they only have to pay a wage of W2. This is lower than wage in a competitive market (W1), there are also fewer workers employed.

Should we increase the state pension age?

Many Western economies face a demographic time bomb – an ageing population, which places strain on government spending and the welfare state. To deal with this situation, governments face several difficult choices –

  1. Raise taxes to pay for pensions,
  2. Shift the emphasis on to the private sector provision of pensions,
  3. Raise the retirement age
  4. Cut other forms of spending to be able to maintain pension commitments.

Recently, the UK chancellor George Osborne, has suggested that he favours a solution which involves automatically linking state pension to life expectancy; this could see the state retirement age, increasing to 70. It is estimated, this could save up to £500bn over 50 years; there would be a very significant opportunity cost to keeping the retirement age at 65.

However, others are more critical of increasing the retirement age. They argue that raising the retirement age will adversely affect low income workers who find it more difficult to save for a private pension. Also, some economists question whether we really have a demographic time bomb, and argue that the fears of an ageing population are exaggerated.

The extent of the problem

The dependency ratio is the ratio of people who are not of working age compared to those who are of working age. If there is a higher % of pensioners then the dependency ratio will rise. Basically a higher dependency ratio means a relatively greater number of benefit recipients to tax payers.

This graph shows that all Western economies face a rise in the dependency ratio (assuming a retirement age of 65). However, the UK’s demographic forecast is not as bad as other countries. This is partly because the UK has had significant levels of immigration and an increase in the population.

How UK spending on pensions has increased

government-spending-percent-gdp-uk-1950-2019 The share of GDP spent on pensions in UK has increased from 2% in 1950 to 8% in 2016, it is forecast to rise towards 10% of GDP by 2062. See: UK pension spending

Arguments for raising the pension age to 70

1. Increasing life expectancy . Increasing life expectancy means that it makes sense to raise the retirement age. When the first state pensions were introduced in 1908, the pension age was set at 70. It was later reduced to 65. But, since the start of the Twentieth Century, we have seen a rapid increase in life expectancy. It means that people are living for longer. If we keep the retirement age the same, we are trying to support an ever increasing % of people’s life in retirement. Rather than seeing it as a bad thing the retirement age is increasing, we should see it as a good thing we are enjoying greater life expectancy. Since 1981, longevity has increased 5.3 years

2. Higher tax revenue. As well as saving the government pension spending, if people work longer it will increase income tax revenues. Increasing the labour supply will also increase the productive capacity of the economy.

3. Will enable the government to increase the value of the state pension. If the retirement age is increased, the government will be able to afford an increase in the real value of the state pension. A higher basic state pension will help reduce poverty without creating disincentives to save that means tested top up benefits do. People may prefer a decent pension spread over a smaller number of years than a limited pension stretched over a longer time period.

3. More flexible labour markets. At the moment, several professions have a fixed retirement age; this means people have to retire at a certain age, even if they would prefer to keep working. Increasing the state pension age, will enable people to work longer. It may be that people work part time towards the end of their working life, but it will help increase the supply of labour. With jobs increasingly non-manual, there isn’t any physical barrier for people to keep working. It means the economy can benefit from highly experienced and highly skilled workers.

4. Better than the alternatives. The alternatives to increasing the retirement age are also unattractive. It would entail placing a higher tax burden on the working population; these higher tax rates could reduce incentives to work.

Mobility of labour

The mobility of labour refers to how easily workers can move to different jobs within the economy. The two main factors of labour mobility are: Geographical mobility – how easy is it for a worker to move between different regions and countries to seek new work. Occupational mobility – how easy is it for a …
