Many people are attracted to work in the private sector, with expectations of greater opportunities for promotion, more variation in work and higher salaries. However, according to the Office for National Statistics, it may be that the oft-talked-of pay differential is actually in the opposite direction. Data from the ONS suggests that public sector workers are paid 14.5% more on average than those working in the private sector.

As is the case with the price of a good, the price of labour (that is, the wage rate) is determined by the forces of demand and supply. Many factors influence the wages that individuals are paid and traditional theory leads us to expect higher wages in sectors where there are many firms competing for labour. With the government acting as a monopsony employer, it has the power to force down wages below what we would expect to see in a perfectly competitive labour market. However, the ONS data suggests the opposite. What factors can explain this wage differential?

Jobs in the public sector, on average, require a higher degree of skills. There tend to be entry qualifications, such as possessing a university degree. While this is the case for many private-sector jobs as well, on average it is a greater requirement in the public sector. The skills required therefore help to push up the wages that public-sector workers can demand. Another explanation could be the size of public-sector employers, which allows them to offer higher wages. When the skills, location, job specifications etc. were taken into account, the 14.5% average hourly earnings differential declined to between just 2.2% and 3.1%, still in favour of public-sector workers. It then reversed to give private-sector workers the pay edge, once the size of the employer was taken out.

Further analysis of the data also showed that, while it may pay to be in the public sector when you’re starting out on your career, it pays to be in the private sector as you move up the career ladder. Workers in the bottom 5% of earners will do better in the public sector, while those in the top 5% of earners benefit from private-sector employment. The ONS said:

Looking at the top 5%, in the public sector earnings are greater than £31.49 per hour, while in the private sector, the top 5% earn more than £33.63 per hour… The top 1% of earners in the private sector, at more than £60.21 per hour, earns considerably more than the top 1% of earners in the public sector, at more than £49.65 per hour.

The data from the ONS thus suggest a reversal in the trend of average public-sector pay being higher than private sector pay, once all the relevant factors are taken into account.

This will naturally add to debates about living standards, which are likely to take on a stronger political slant as the next election approaches. It is obviously partly down to the public-sector pay freeze that we saw in 2010 and also to a reversal, at least in part, of the previous trend from 2008, where public-sector pay had been growing faster than private-sector pay. However, depending on the paper you read or the person you listen to, they will offer very different views as to who gets paid more. All you need to do in this case is look at the titles of the newspaper articles written by the Independent and The Telegraph! Whatever the explanation, these new data provide a wealth of information about relative prospects for pay for everyone.

Business performance is always affected by the economy and we can always look at the economic theory to explain why profits rise and fall. Some companies prosper during recession, whereas others decline and the key is to understand the economics behind the data. This blog takes a look at the performance of a variety of companies and asks you to think about the economic theory behind it.

The world of betting has grown significantly and the profits of companies in this market, while certainly linked to economic performance, is also dependent on sport results. Paddy Power has announced pre-tax profits of €141m for 2013, an increase from €139.2m, despite sporting results causing profit performance to fall. On the part of football clubs, Liverpool FC saw a loss emerge for the 2012-2013 financial year, whereas Newcastle’s profits rose by 900% to £9.9m. What factors can explain the vastly different performance (off and on the pitch) of these two clubs?

In the USA, Radio Shack has been forced to close 1100 stores. This is, in part, as a response to a change in the way we are shopping. More and more consumers are purchasing goods online and Radio Shack is therefore experiencing growing competition from online retailers. Sales fell by 10% last year and even during the fourth quarter sales continued to decline.

Companies based in the largest economy in Europe have also experienced declines in performance, showing that a strong performing country doesn’t imply the same for companies operating in it. RWE, Germany’s biggest energy provider, has not made a loss since 1949. However, in 2013, this company posted its first annual loss in over 60 years: a loss of £2.28bn. With energy being in constant demand and criticism being levelled at UK energy providers for the high profits they’re making, the economics behind these data is important.

In better news for a company, Thorntons has boasted a significant increase in pre-tax profits, with much of this due to strong trading in the months leading up to Christmas and a sensible business strategy, involving selling more in supermarkets. Thorntons has cut its number of stores, but its profitable position has been saved by a good business strategy and this is going to lead to significant investment by the company.

Another strong performance was recorded by Berkshire Hathaway, an investment firm run by Warren Buffett. The company made a profit of £11.6bn in 2013, a significant increase on its 2012 performance. It is the insurance, rail and energy parts of the business that have contributed to the big increase in profits.

These are just some recent examples of data on business performance and your job is to think about the economic theory that can be used to explain the varying performance of different companies.

The housing market is often a good indicator of the level of confidence in an economy. Prior to the credit crunch, there had been a house price bubble and as the financial crisis began and economies plunged into recession, house prices began to fall significantly. In the last few months, the housing market has begun its recovery and data from the ONS shows average property prices up by 5.4% across the UK in November, compared with a year earlier.

When we analyse the housing market, or any market, we have to give attention to both demand-side and supply-side factors. It is the combination of these factors that yields the equilibrium price. For most people, buying a house will represent their single biggest expenditure and so there are many factors that need to be considered.

The demand for housing is affected by incomes, by the availability of mortgages, the rate of interest and hence the cost of mortgages. Speculation also tends to be a key factor that influences the demand for houses, as people may buy houses if they believe that prices will soon rise. Of course, simply by responding to expectations about future price changes causes the price changes to happen – a classic case of self-fulfilling speculation.

The availability of mortgages has been one of the biggest factors increasing the demand for and hence price of houses in recent months. More individuals have been able to get onto the property ladder and, with confidence returning to the market, these factors have caused a rightward shift in the demand for owner-occupied houses.

Another key factor has been the growth in the demand for housing as an investment opportunity, in particular from the global super rich. This has been of particular concern in London, where there are fears of a housing bubble developing and of lower-income households being priced out of the market.

At the same time, there has been a growth in the supply or housing and thus a rightward shift of the supply curve. Ceteris paribus, this would push down average prices. However, the data suggest that house prices, especially in London, have increased, implying that the impact on price of the increase in demand has more than offset the downward force in prices from the increase in supply. Part of this can be explained by the demand-side factor of an increase in demand for top-end properties, which ‘has been distracting developers from the need for more affordable accommodation.’ When asked about the changes observed in the London housing market, Civitas said:

London is one of the most – if not the most – attractive property markets for international investors all over the world. It is also at the centre of an affordability crisis in the UK which is having serious consequences for younger people and the less well-off…For too many it [investment at the top end of the market] is providing financial shelter rather than human shelter.

With the upward pressure on house prices, many are now warning of another bubble developing in London. When comparing house prices in London with a Londoner’s income, Ernst and Young found that house prices were 11 times average annual income. Data like this were last seen prior to the financial crisis and it is this which has led to concerns of a post-crisis bubble.

There are suggestions that more action is needed to combat this bubble, such as imposing a limit in income multiples in relation to how much of a mortgage you are able to borrow. Another criticism levelled at the market is the government’s Help to Buy scheme, which critics argue is raising demand and pushing up prices, because there is no matched increase in supply.

So, with the rest of the market returning to some semblance of normality, it is currently just London showing signs of a bubble and we are all well aware of what the consequences might be if a bubble is allowed to grow and then eventually burst. The following articles consider the housing market.

Conservative Party leaders are considering the benefits of an above-inflation rise in the minimum wage. This policy has been advocated by both the Labour Party and the Liberal Democrats as a means of helping the lowest paid workers. From 2008 to 2013, minimum wage rates fell 5.2% in real terms: in other words, nominal increases were less than the increase in both the RPI and CPI (see UK minimum wage: a history in numbers).

Advocates of a real rise in the minimum wage argue that not only would it help low-paid workers, many of whom are in severe financial difficulties, but it would benefit the Treasury. According to Policy Exchange, a free-market think tank closely aligned to the Conservative Party, increasing the minimum wage by 50p would save the Government an estimated £750m a year through higher tax revenues and lower benefit payments.

But even such a rise to £6.81 would still leave the minimum wage substantially below the living wage of £8.80 in London and £7.65 in the rest of the UK, as estimated by the Living Wage Foundation (see The cost of a living wage). Although many businesses are now paying at least the living wage, many others, especially small businesses, argue that a rise in the minimum wage above the rate of inflation would force them to consider cutting the number of employees or reducing hours for part-time workers.

Meanwhile, in the USA 13 states have raised their minimum wage rates from the 1st January 2014 (see). Some of the rises, however, were tiny: as little as 15 cents. In a couple of cases, the rise is $1. Currently 21 states and DC have minimum wage rates above the Federal level of $7.25 (approx. £4.40); 20 states have rates the same as the Federal level; 4 states have rates below the Federal level. At $9.32 per hour, Washington State has the highest state minimum wage; the lowest rates ($5.15) are in Georgia and Wyoming. In 5 states there is no minimum wage at all. As the ABC article below states:

The piecemeal increases at the local level are occurring amidst a national debate over low wages and income inequality. Fast food and retail workers have been staging protests and walking off work for more than a year, calling for better pay and more hours. Currently, fast food workers nationally earn an average of about $9 per hour.

Workers from McDonald’s, Wendy’s, Burger King and other fast food joints are calling for $15 per hour. Wal-Mart workers organizing as part of the union-backed OUR Walmart aren’t asking for a specific dollar amount increase, but they say it’s impossible to live on the wages they currently receive.

President Obama has been throwing his weight behind the issue. Earlier this month, the President said in a speech that it’s “well past the time to raise the minimum wage that in real terms right now is below where it was when Harry Truman was in office.” But such legislation has a bleaker outlook if it reaches the Republican-led House of Representatives. House Speaker John Boehner has said that raising the minimum wage leads to a pullback in hiring.

So what are the costs and benefits of a significant real rise is the minimum wage on either side of the Atlantic? The articles explore the issues.

According to the supply and demand model, we would expect the price of turkeys to be high at this time of year. After all, last Christmas in the UK over 10 million turkeys were consumed and, therefore, this high level of demand should cause prices to rise. This is certainly what happens in other markets when there is a substantial increase in demand.

However, evidence from Thanksgiving in the USA suggests that this might not be the case. According to this article from the New York Times, data suggests that the price of frozen turkeys in the US falls by around 9% between October and November, coinciding with the substantial increase in demand for Thanksgiving celebrations. The article then goes on to suggest a number of plausible demand and supply-side explanations for this fall in price.
