The OBR are forecasting that household spending will increase in real terms in 2012 by 0.5 per cent and by a further 1.3 per cent in 2013. This is on the back of a fall in real consumption in 2011 of 1.2 per cent. Therefore, the rebound in consumer spending is predicted to be only fairly modest. The long-term average annual real increase in household spending is around 2½ per cent.
The drag on consumer spending growth remains the weakness of growth in real disposable income. The post-tax income of the household sector fell in real terms by 1.2 per cent in 2011 and is expected to fall by a further 0.2 per cent in 2012. It is not until 2015 that growth in real disposable income returns to its long-term average which, unsurprisingly, is roughly the same as that of household sector spending.
As we noted in our earlier blog, the OBR’s short-term figures on spending growth critically depend on the ability of households to absorb the negative shocks to their real income. Empirical evidence tends to show that household spending growth is less variable than that in income and that households try and smooth, if they can, their spending. Therefore, the marginal propensity of households to consume out of changes in their income is below 1 in the short-run. This is consistent with the idea that households are consumption-smoothers disliking excessively volatile spending patterns.
The actual figures for consumption and income growth in 2011 help to show that consumption-smoothing cannot be taken for granted. In 2011, the fall in consumption exactly matched that in income. An important impediment to consumption-smoothing in recent times has been the impact of the financial crisis on bank lending. Banks have become more cautious in their lending and so households have been less able to borrow to support their spending in the face of falling real incomes. Another impediment to consumption-smoothing is likely to be the continuing unease amongst households to borrow (assuming they can) or to draw too heavily on their savings. In uncertain times, households may feel the need for a larger buffer stock of wealth to act as a security blanket.
In short, the latest OBR figures suggest that the growth in consumption in the medium-term will remain relatively weak. Retailers are likely to ‘feel the pinch’ for some time to come.
A key determinant of our economy’s rate of growth over the year ahead is likely to be the behaviour of households and, in particular, the rate of growth in consumer (or household) spending. In other words, your appetite for spending will help to determine how quickly the economy grows. The importance of household spending for the economy is straightforward to understand given that it accounts for roughly two-thirds of the total demand for firms’ goods and services, i.e. two-thirds of aggregate demand. In its November 2011 Economic and Fiscal Outlook the Office for Budget Responsibility presents it forecasts for economic growth and household spending. The following table summarises these forecasts.

The OBR are forecasting that household spending will fall in real terms in 2011 by 1.1 per cent and grow by only 0.2 per cent in 2012. This is not good news for retailers nor, of course, for the economy. The drag on consumer spending growth is largely attributed to expected falls in real disposable (after-tax) incomes in both 2011 and 2012. In 2011, the household sector’s real income is forecast to decline by 2.3 per cent and then by a further 0.3 per cent in 2012.
The OBR’s figures on spending growth critically depend on the ability of households to absorb the negative shock to their real income. Empirical evidence tends to show that household spending growth is less variable than that in income and that households try and smooth, if they can, their spending. This means that the marginal propensity of households to consume out of changes to their income is below 1 in the short-run. In fact, the shorter the period of time over which we analyse income and consumption changes the smaller the consumption responses become. This is consistent with the idea that households are consumption-smoothers disliking excessively volatile spending patterns. In other words, the size of our monthly shop will usually vary less than any changes in our real income.
Of course, consumption-smoothing cannot be taken for granted. Households need the means to be able to smooth their spending given volatile and, in the current context, declining real incomes. Some economic theorists point to the importance of the financial system in enabling households to smooth their spending. In effect, households move their resources across time so that their current spending is not constrained solely by the income available to them in the current time period. This could mean in the face of falling real income perhaps borrowing against future incomes (moving forward in time expected incomes) or drawing down past savings.
The ability of households to move future incomes forward to the present has probably been impaired by the financial crisis. Banks are inevitably less cautious in their lending and therefore households are unable to borrow as much and so consume large amounts of future income today. In other words, households are credit-constrained. Furthermore, it is likely that households are somewhat uneasy about borrowing in the current climate, certainly any substantial amounts. Uncertainty tends to increase the stock of net worth a household would like to hold. A household’s net worth is the value of its stock of physical assets (largely housing wealth) and financial assets (savings) less its financial liabilities (debt). If households feel the need for a larger buffer stock of wealth to act as a sort of security blanket, they will not rush to acquire more debt (even if they could) or to draw down their savings.
The impairment of the financial system and the need for a buffer stock are two impediments to households smoothing their spending. They tend to make consumption more sensitive to income changes and so with falling incomes make it more likely that consumption will fall too. There are other related concerns too about the ability and willingness of consumers to smooth spending. Uncertainty arising from the volatility of the financial markets imposes liquidity constraints because households become less sure about the value of those savings products linked to the performance of equity markets. Consequently, they become less certain about the money (liquidity) that could be raised by cashing-in such products and so are more cautious about spending. Similarly, the falls in house prices have reduced the ability of households to extract housing equity to support spending. Indeed, with fewer transactions in the housing market the household sector is extracting less housing equity because it has been quite common, at least in the past, for households to over-borrow when moving and use the excess money borrowed to fund spending.
In short, there are many reasons to be cautious about the prospects for household spending. The expected decline in real income again in 2012 will ‘hit’ consumer spending. The question is how big this ‘hit’ will be and crucially on the extent to which households will be able to absorb it and keep spending.
