Let’s face it – no-one likes paying tax! After all, to see your monthly pay decline by £1000 through taxation and national insurance has got to hurt. Yet, taxation and national insurance contributions are essential sources of government revenue to finance benefits and public and merit goods.

However, with so much attention given to the UK’s ‘culture of dependency’, many people are increasingly angry with having to pay so much in taxation to see it being spent by the government on individuals who in some cases choose not to work and at the same time seeing other rich people paying so little in taxation. The increase in the top rate of tax received a lot of coverage. Although it did make the tax system more progressive, there were many concerns that it would lead to lower growth, a lack of innovation and enterprise and increased tax evasion and avoidance, as the super-rich were being hit with phenomenal tax bills. The post on the 50p income tax available here is worth looking at again to think about the effect that taxes have on incentives.

The issue of tax avoidance is by no means new, but with a large budget deficit in the UK, tax avoidance by the super-rich has become something that everyone has an opinion on. The average household has seen its income squeezed more and more, as the government continues its efforts to cut the deficit. The fact that the super rich are avoiding sometimes millions in taxation, while the average household struggles to pay even the basic rate of tax, creates a rather contentious issue. The Chief Secretary to the Treasury, Danny Alexander, has said that the basic rate of tax could be cut by 2p in the pound if tax avoidance came to an end. He commented to the BBC’s Sunday Politics Programme that:

‘We have to make sure that everybody, especially the rich and famous, are paying their fair share of tax…These sorts of schemes that save wealthy people potentially tens of millions of pounds in tax, they are paid for by everybody else… If we could narrow the tax gap in this country by a quarter we could reduce income tax for every basic rate payer by 2p in the pound.’

This would clearly have some very positive effects on some of the poorest people living in the UK.

There is a variety of tax avoidance schemes available and the one receiving the most attention at present is the Jersey-based K2 scheme, which Jimmy Carr and others are thought to be using. The Public Accounts Committee will be reporting on the problem of using private companies to pay salaries, as a means of avoiding income tax and national insurance contributions.

If tax avoidance could be stopped, or at least reduced, then not only could basic rate tax payers benefit, but it might go some way to cutting the budget deficit, giving the government more flexibility in stimulating the economy. According to HMRC, tax avoidance and evasion cost the economy some £42 billion – enough to pay off one-third of Britain’s budget deficit.

A recent post on this blog referred to what sounds a fascinating new book, What Money Can’t Buy: The Moral Limits Of Markets, by Michael Sandel. The Guardian also recently featured an extract from this book.

As the earlier blog post discussed, our lives are now dominated by markets. Economists typically believe markets are the best way to allocate resources as, if the market mechanism works correctly, the resulting equilibrium maximizes economic welfare as measured by the sum of consumer and producer surplus. In particular, all consumers that are willing to pay a price above the market price are able to buy the product.

Fundamental to the measurement of consumer welfare is the notion that consumers will be prepared to buy a product as long as their willingness to pay exceeds the price. It therefore follows that consumers are more likely to buy the product as the price falls and, if they do so, gain increasing surplus. However, the extract from Michael Sandel’s book provides a number of interesting examples which suggest that in some situations this might not be the case.

One example concerns the storage of nuclear waste in Switzerland. When surveyed, 51% of the residents of the small Swiss village of Wolfenschiessen, said that they would be prepared to accept the waste being stored nearby. However, somewhat surprisingly, this figure fell to 25% when the residents were told that they would be compensated for the inconvenience. Furthermore, the figure remained at this low level even when the proposed compensation was increased to over £5000 per person.

Sandel argues that this is because, once compensation is introduced, financial incentives crowd out public spirit. He suggests that:

putting a price on the good things in life can corrupt them.

For economists, this potentially has important implications for how we evaluate market outcomes and our belief that the market equilibrium is always the optimal outcome. Furthermore, it suggests that in some circumstances allowing the market mechanism to allocate resources may not be the ideal solution.

Oil is a commodity like any other – its price is affected by demand and supply. Back in 2003, with the impending war in Ira and strikes in Venezuela, oil prices increased and continued to do so as further supply concerns developed in Saudi Arabia, Russia and Nigeria. This upward trend continued until 2008, when with the growing banking turmoil and demand for oil falling, the price began to decline. However, the crisis in Libya is only making matters worse. Its credit-rating has been downgraded with the potential for it to be lowered further and concerns are deepening about the country’s crude exports. As Libya is the world’s 12th largest exporter of oil, these supply concerns have started to push up oil prices once more.

With inflation rates already high and political turmoil pushing oil prices up further, consumers and firms are feeling the squeeze. These changes have also been reflected on stock markets across the world. Analyst, Michael Hewson at CMC Markets said:

‘Given the fact that we have seen massive gains in stock markets over the last few months, investors have been nervous about a possible correction for some time… The tensions in the Middle East with Libya imploding and concerns that the unrest could spread to Saudi Arabia could provide a catalyst for (this) correction.’

The disruption in the Middle East has caused companies such as Eni of Italy and Repsol YPF of Spain to shut down production, leading to output losses of some 22% of Libya’s production. As supply contracts from this region, prices will inevitably rise. However, the Saudi oil Minister has said that he is ready to boost production to offset any decline, but that at present there is no oil crisis. So, what can we expect to happen to oil prices in the coming months? It will all depend on changes in demand and supply.

Ahead of Lord Davies’s report on Boardroom equality, he will be somewhat alarmed by the survey results carried out by the Institute of Leadership and Management, which found that 73% of women felt that they still face barriers to top-level promotion. Quotas are a suggestion to break down this barrier. As Sheelagh Whittaker, a non-executive directive of Standard Life said:

‘I am a big supporter of quotas. I believe that we will only have true equality when we have as many incompetent women in positions of power as incompetent men.’

However, others say that quotas are not the answer, as they don’t actually change the fundamentals. Forcing compliance for equality in the workplace is not the same as equality in the workplace. There are a number of other reasons behind fewer women in top level positions, including less confidence and ambition, a more risk-averse attitude to promotion, as well as more women than men aspiring to run their own company, rather than seek promotion within a firm. So does discrimination still remain in the workplace or are there other explanations for the fact that only 12% of FTSE 100 directors are women?

The owner-occupied housing market has seen widespread coverage. With house prices falling throughout the recession and problems accessing mortgages for many people, it is this sector of housing that has received most attention. However, it is rental homes that we’ll be considering here and a new strategy being adopted by landlords. As access to mortgages dried up, people instead turned to renting. Demand for rental properties began to increase, such that competition between potential tenants increased significantly. Not only has there been a substantial increase in rents – up by some 35%, but it has also led to a new ‘sealed bid’ strategy.

A strategy that is often used for purchasing houses is where potential buyers submit sealed bids and it is this approach which is now spreading to the rental sector, as demand and competition for properties increases. Potential tenants are required to submit a sealed bid, containing the amount that they are willing to pay to rent out the property and all this must be done within a deadline. Whoever submits the highest bid ‘wins’ the property and hence tenants are encouraged to submit a bid at or close to the maximum they are willing to pay. Landlords insist that they are not trying to force tenants to pay more, but that it is simply the most effective way of letting properties that are short in supply, but face significant demand. As the BBC News article states:

‘It seems that with the current state of the housing market, sealed bids will be here to stay – as long as many would-be renters are chasing a dwindling supply of good rental homes.’

Questions

  1. Using a supply and demand diagram, explain the trend we have seen in the rental market, thinking about the impact on demand, supply and hence on price. How does this explain why sealed bids have been used to combat the increased competition?
  2. Which factors have affected (a) the demand for rental properties and (b) the supply of rental properties? How is the elasticity of demand and supply relevant here in terms of the impact on price?
  3. To what extent is a sealed bid format fair on potential tenants? Who does such a strategy favour?
  4. How could this sealed bid strategy be an example of price discrimination?
  5. What is likely to happen to your consumer surplus if you have to submit a sealed bid?
