Economics CourseworkQuestion 1: UK Housing Price PatternsInterpretation of data

House prices in the UK have followed a similar pattern, increasing by over 35% between 2002 and 2007 and

slowing down after that. However, prices in London have been consistently higher than in the rest of the UK

with an average gap of 122,000 throughout 2002 2011. Investigating the year -to-year percentage change

also shows that London prices have been more volatile from 2006 onwards with a standard deviation on

returns of 11 compared to 7.

To explain these patterns, we will use the supply and demand model and focus firstly on the 2002 2007 price

increase. This will then lead to the discussion of the slow down and the differences between London and UK

housing prices.

housing prices between 2002 and 2007.

Supply-side consideration1

There is consensus supported by academic research (Meen, 2005, p963) and government reports (Barker

Review 2006), that the housing supply in the UK was highly price inelastic over the last decade. The reasons

behind this are still debated but two possible factors were the restriction of land supply and a lack of housing

developments undertaken during the period.

Tougher environmental laws, safety regulations (no construction on flood plains, unstable soil) and excessiverestrictions from the planning system constraining the supply of land made available for development,

increasing its price. At the same time, the fall in long -term real interest rates further raised the price of long

duration assets such as land as investors viewed it as safe and profitable. The uncertainty associated with the

lag time needed for permits and construction further reduced the marginal benefit of developing land such that

overall, fewer than expected dwellings were built.

As a result, despite the price rises, the UK housing stock increased at a rate bellow 1% for several years with

only 175,000 new dwellings built in 20012.

Demand-side considerations

Since the supply of housing in the UK was inelastic, the substantial increase in average prices must be due to a

succession of outwards shifts of aggregate demand caused by combination of demographic, macro-economic

and behavioral factors.

The increase in the size of the UK population3 has put some upward pressure on demand for housing because it

has few good substitutes. Moreover, the low interest rate environment coupled with a loosened credit supply

through easily available mortgages significantly increased the buying power of consumers for houses. These

factors started a positive feedback cycle in which excess liquidity and expectations of future price rises further

pushed up aggregate demand leading to a type of housing market bubble.

Supply and Demand Model

The arguments stated above are illustrated in Fig. x in which the inelastic supply causes the outwards shift of

demand from D2002 to D2007 to be translated into a significant price increase from P2002 to P2001.

Slow down after 2007 and price differences between London and the UK

The subprime crisis and recession had an immediate effect on the UK housing market, which fell by 11%

between 2007 and 2009. The reasons for this contrast with the previous boom: aggregate demand fell suddenly

due to a shortage of credit and deteriorating confidence. The effect on prices was worsened by rising

unemployment and excessive mortgage leverage, which caused many houses to be repossessed and sold at

discounted prices, temporarily increasing supply on the market4.

Fig 5 shows the steep fall in the mortgage supply in 2007 which correlates with the UK housing prices5

It is interesting to note that later movements of house prices and mortgages have followed a pattern similar to

that of the UK economy, improving quickly in 2010 but slowing down as the debt crisis brings new uncertainty.

To conclude, we shall highlight reasons behind the persistent price gap between London and the rest of the UK.

Planning restrictions such as the metropolitan green belt and strong economic growth have particularly limited

the supply of residential land and housing in London. Adding to this is a high average earning level and a

perceived desirability that attracts international buyers and investors in search of lower risk speculative assets.

These factors amplify the supply and demand mechanism previously described and cause the housing market

to be both more expensive and volatile in times of crisis.
