From lower case to capital GROWTH! How capital spending boosted growth in Q1

The second estimate of UK output for Q1 2010 from the Office for National Statistics reports that the economy grew by 0.3%. The first estimate, based on limited data, put growth in Q1 at 0.2%. But, it appears that more recently available data picked up evidence of stronger growth in the latter stages of the quarter, particularly in the production industries, such as manufacturing, as well as in capital spending by firms.

When analysed in terms of the composition of demand for our firms’ goods and services, there has been something of a rebound in investment expenditure. This follows a marked collapse during 2008 and the first half of 2009. In 2010 Q1 investment volumes increased by 4.2% on the back of a 2.4% rise in the last quarter of 2009.

This rebound in the investment figures across the last two quarters has partly been driven by firms running down their stockpiles of finished goods at a considerably slower rate. When firms build up their stocks of inventories for sales in future periods they are deemed to be engaging in investment. When firms then ‘tap into’ these inventories, as they have been since Q4 2008, they are disinvesting. It is now the case that the pace of disinvestment through running down inventories is slowing. This reflects a pick up in the demand for firms’ goods and services and, hopefully, an expectation of stronger future demand.

More encouragingly, the rebound in investment volumes in Q1 also reflected an increase in gross fixed capital formation, i.e. an increase in the purchase of non-financial fixed assets used in production, such as machinery. Gross fixed capital formation increased in Q1 by 1.5%. This was the first quarter since Q2 2008 in which there has been an increase in the volume of capital purchases by firms. Again, this is likely to reflect increased optimism about future demand since these assets are purchased to do one thing – to produce goods and services!

The improvement in the investment numbers is such that the volume of investment in Q1 2010 was 0.6% higher than it was in Q1 2009. This is largely the impact of a slower rate of disinvestment by firms through running down inventories since despite the rise in gross capital formation in Q1 2010 it still came in 5.7% lower than in Q1 2009. Nonetheless, it will be interesting to see whether the recent improvement in the UK’s investment numbers is maintained as we go forward.

Of particular concern is whether the volume of capital purchases can continue to grow. Can these purchases help to both boost growth now and our economy’s potential output in the medium term? Some of the key issues in determining the answer to this are likely to include: (i) the extent to which aggregate demand grows; (ii) the impact of fiscal consolidation measures on both firms and consumers; (iii) sentiment (confidence) across firms – especially of their own medium-term prospects; and (iv) the ability of firms to access credit from financial institutions. One can undoubtedly add many other issues to this list. One thing is for sure, these are very uncertain times indeed!

  1. Why do the National Accounts record a positive change in inventories as investment and a negative change in inventories as disinvestment?
  2. What factors might explain the running down of inventories across firms in the UK since Q4 2008? Why didn’t this start in Q2 2008 when the UK economy went into recession?
  3. In Q1 2010 the running down of inventories was worth, at 2005 prices, some £1.347 billion. This was considerably less than the £4.883 billion in Q3 2009 and the £2.596 billion in Q4 2009 (again at 2005 prices). Why might the pace of disinvestment be slowing?
  4. Of what importance do you think, firstly, the change in inventories and, secondly, gross capital fixed formation are for an economy’s potential output?
  5. What arguments do you think there are for distinguishing between different types of investment goods and services when considering our future economic growth?
