Forecasting the future state of economies is difficult at the best of times. Forecasters frequently get it wrong. To see this, just look at forecasts for the current point in time made two or three years ago – or even six months ago, given the current dire circumstances. They were often way-off mark.

But why are forecasts often so inaccurate? The problem is that in the short run the state of the economy depends on the level of aggregate demand; and that, in turn, depends crucially on confidence – both of consumers and business. But confidence is a ‘will-o’-the-wisp’ thing. Confidence can evaporate with bad news, making the situation much worse. Likewise, good news can lead to rapidly growing optimism, which in turn stimulates consumption, investment and growth. Humans are fickle creatures – and the media do not help here, playing on fears or hyping-up good news.

The following articles look at forecasts made in April 2009, when economies around the world were deep in recession. Was this recession the start of something much worse? Or were economies soon to bounce back, taking up the slack created by the recession? Forecasters were being sorely tested. It will be interesting to see in a year’s time just how accurate, or inaccurate, they were.

Questions

  1. Why do forecasters differ so markedly from each other?
  2. Other than an unexpected rise or fall in confidence, what else could make forecasts turn out to be wrong?
  3. To what extent is economic forecasting similar to and different from weather forecasting?

In a recession, the government’s budget will go into cyclical deficit as tax revenue falls and government spending on unemployment and other benefits rises. Provided the deficit is purely cyclical, it can be seen as desirable since it acts as an automatic fiscal stabiliser, boosting aggregate demand and helping to pull the economy out of recession. Once the economy returns to potential national income (i.e. a zero output gap), the deficit would disappear. At potential national income (Yp), government expenditure (including benefits) will equal tax revenue. The budget is in balance.

Again, provided that the deficit is only cyclical, discretionary expansionary fiscal policy that further deepens the deficit will not be a problem for public finances in the future. Once the economy pulls out of recession, the discretionary policy can be relaxed and the higher national income will eliminate the cyclical deficit.

But the problem the Chancellor of the Exchequer faced in the Budget (on 22/4/09) was not just one of tackling the recession. The UK economy has seen a massive growth in the structural deficit. His forecast is for the total deficit to be £175bn in 2009. But, according to calculations by the Institute for Fiscal Studies, even when the recession is over and the output gap has been closed, there will still be an annual deficit of around £140bn. This is not cyclical; it’s structural.

So why is there this huge structural deficit? And what is the solution? Will the solution slow down recovery? The following articles look at the issues.

Questions

  1. Explain the terms ‘cyclical deficit’ and ‘structural deficit’.
  2. Draw a diagram showing how government expenditure (including benefits) and tax revenue vary with national income. The diagram should show the sitation with no structural deficit: i.e. the two lines should cross at potential national income. Illustrate (a) a cyclical deficit where actual national income is below potential national income (a negative output gap) and (b) a cyclical surplus where actual national income is above potential income (a positive output gap).
  3. Now, on the same diagram, shift the two lines to illustrate a situation of structural deficit.
  4. Consider whether the government should attempt to increase or reduce the budget deficit at a time of recession.
  5. Why has the structural deficit become so severe over the past year?
  6. How quickly should the government set about tackling the structural deficit?

Every six months the OECD publishes its Economic Outlook. This gives annual (and some quarterly) macroeconomic data for each of the 30 OECD countries, for all 30 countries together and for the eurozone. There are 63 tables covering most of the major macroeconomic indicators, most going back 13 years with forecasts for the next two years. OECD Economic Outlook is normally published in June and December.

Similarly, every six months the European Commission’s Economic and Financial Affairs Directorate publishes its European Economy Statistical Annex. This gives annual data for 76 macroeconomic variables for each of the EU countries, plus the USA and Japan. Most of the tables go back to 1970 and forecast ahead for two years. There is also a separate publication, Economic Forecasts. The statistical appendix to this publication has 62 tables, again covering a range of macroeconomic data. The tables go back to 1992 and again forecast ahead for two years. There is a lot of useful commentary about the individual economies of the EU and other major economies, such as the USA, Japan, China and Russia. Both publications normally appear in May and November.

Another organisation to publish 6-monthly forecasts is the International Monetary Fund. The Statistical Appendix of the Word Economic Outlook (after clicking on this, go to link on right), normally published in April and October, gives macroeconomic data for most economies and regions of the world. Forecasts are made ahead for two years and for five years.

The state of the world economy was so severe in early 2009 and was deteriorating so rapidly that earlier forecasts proved far too optimistic. In early 2009, all three organisations published interim forecasts – the European Commission and the IMF in January and the OECD at the end of March. They painted a much bleaker picture than the forecasts published at the end of 2008. What will the next set of forecasts look like? Will they be even bleaker?

The following links take you to these interim forecasts and to articles commenting on them.

Questions

  1. Compare the forecasts for GDP growth, unemployment, inflation and output gaps for some of the major economies made by the OECD at the end of March with those made by the European Commission and the IMF in January and with those made by all three organisations in the autumn of 2008. Why, do you think, are there such large divergences in the forecasts?
  2. For what reasons might the OECD March forecasts turn out to be (a) much too pessimistic; (b) much too optimistic?
  3. In the light of the forecasts, should countries adopt further strongly expansionary fiscal policies – something rejected at the G20 summit in Early April (see news item Saving the world)?
