In 2008 and 2009, as the global recession deepened, so governments around the world turned to Keynesian policies. Aggregate demand had to be boosted. This meant a combination of fiscal and monetary policies. Fiscal stimulus packages were adopted, combining increased government expenditure and cuts in taxes. On the monetary policy front, central banks cut interest rates to virtually zero and expanded the money supply in bouts of quantitative easing.
The global recession turned out not to be a deep as many had feared and the Keynesian policies were hailed by many as a success.
But how the tide is turning! The combination of the recession (which reduced tax revenues and increased welfare spending) and the stimulus packages played havoc with public finances. Deficits soared. These deficits had to be financed, and increasingly credit agencies and others were asking how sustainable such deficits were over the longer term. These worries have been compounded by the perilous state of the public finances in countries such as Greece, Portugal, Ireland and Hungary. The focus has thus turned to cuts. In fact there is now an international ‘competition’ as to which country can wear the hairiest hair shirt. The new Coalition government in the UK, for example, is busy preparing the general public for deep cuts to come.
We are now seeing a re-emergence of new classical views that increased deficits, far from stimulating the economy and resulting in faster growth, largely crowd out private expenditure. To prevent this crowding out and restore confidence in financial markets, deficits must be rapidly cut, thereby allowing finance to be diverted to the private sector.
But if the contribution to aggregate demand of the public sector is to be reduced, and if consumption, the largest component of aggregate demand, is also reduced as households try to reduce their reliance on borrowing, where is the necessary rise in aggregate demand to come from? We are left with investment and net exports – the remaining two components of aggregate demand, where AD = C + G + I + (X – M).
But will firms want to invest if deficit reduction results in higher taxes, higher unemployment and less spending by the government on construction, equipment and many other private-sector goods and services. Won’t firms, fearing a decline in consumer demand, and possibly a ‘double-dip recession’, hold off from investing? As for export growth, this depends very much on growth in the rest of the world. If the rest of the world is busy making cuts too, then export growth may be very limited.
The G20, meeting in Korea on 4 June, wrestled with this problem. But the mood had definitely turned. Leaders seemed much more concerned about deficit reduction than maintaining the fiscal stimulus.
The following articles look at the arguments between Keynesians and new classicists. The disagreements between their authors reflect the disagreements between economists and between politicians about the timing and extent of cuts.

Questions
- Summarise the arguments for and against making rapid cuts in public-sector deficits.
- What forms can crowding out take? Under what circumstances will a rise in public-sector deficits (a) cause and (b) not cause crowding out?
- Assess the policy measures being proposed by the G20.
- How important is confidence for the success of (a) fiscal stimulus packages and (b) deficit reduction policies in boosting economic growth?
Should economists have foreseen the credit crunch? A few were warning of an overheated world economy with excessive credit and risk taking. Most economists prior to 2007/8, however, were predicting a continuation of steady economic growth. Inflation targeting, fiscal rules and increasingly flexible markets were the ingredients of this continuing prosperity. And then the crash happened!
So why did so few people see the downturn coming? Were the models used by economists fundamentally flawed, or was it simply a question of poor assumptions or poor data? Do we need a new way of modelling the economy, or is it simply a question of updating theories from the past? Should, for example, models become much more Keynesian? Should we abandon the new classical approach of assuming that markets are essentially good at pricing in risk and that herd behaviour will not be seriously destabilising?
The following podcast looks at these issues. “Aditya Chakrabortty’s joined in the studio by the Guardian’s economics editor Larry Elliott, as well as Roger Bootle, the managing director of Capital Economics, and political economist and John Maynard Keynes biographer Robert Skidelsky. Also in the podcast, we hear from Nobel prize-winning economist, Elinor Ostrom, Freakonomics author Steven Levitt, and UN advisor and developmental economist Daniel Gay.”

Questions
- Why did most economists fail to predict the credit crunch and subsequent recession? Was it a problem with the models that were used or the data that was put into these models, or both?
- What was the Washington consensus? To what extent did this consensus contribute to the current recession?
- What is meant by systemic risk? How does this influence the usefulness of ‘micro’ financial models?
- What particular market failures were responsible for the credit crunch?
- What is meant by ‘rational behaviour’? Is it reasonable to assume that people are rational?
- Is macroeconomics too theoretical or too mathematical (or both)? If you think it is, how can macroeconomics be reformed to improve its explanatory and predictive power?
- Does a ‘really good economist’ need to have a good grounding in a range of social sciences and in economic history?
This podcast is from the Library of Economics and Liberty’s EconTalk site. In it, Scott Sumner of Bentley University discusses with host Russ Roberts the role of monetary policy in the USA since 2007 and whether or not it was as expansionary as many people think.
In fact, Sumner argues that monetary policy was tight in late 2008 and that this precipitated the recession. He argues that the standard indicators of the tightness or ease of monetary policy, namely the rate of interest and the growth in the money supply, were misleading.

Questions
- Why is it important to look at the velocity of circulation of money when deciding the effect of interest rate changes or changes in the monetary base? Can the Fed’s failure to take velocity sufficiently into account be seen as a cause of the recession?
- Is there evidence of a liquidity trap operating in the USA in late 2008?
- How could the Fed have pursued a more expansionary policy, given that interest rates were eventually cut to virtually zero and the monetary base was expanded substantially?
- Why does Sumner argue that monetary policy should focus on influencing the growth in aggregate demand?
- How useful is the quantity equation, MV = PT (or MV = PY) in understanding the role and effectiveness of monetary policy?
- What is the Keynesian approach to monetary policy in a recession? How does this differ from the monetarist approach? Are both approaches focusing on the demand side and thus quite different from supply-side analysis of recession?
- Why is the consumer prices index (CPI) a poor indicator of a nominal shock to the economy? Should the central bank focus on nominal GDP, rather than CPI, as an indicator of the state of the economy and as a guide to the stance of monetary policy?
- What are the strengths and weaknesses of using a Taylor rule as a guide to monetary policy? Would nominal GDP futures be a better target for monetary policy?
The following two clips look at John Maynard Keynes’s contribution to macroeconomics and whether his theories have been proved to be correct by the events of the past two years.
“What would John Maynard Keynes make of the financial crisis and the credit crunch?” In the first clip, “Author Peter Clarke, former professor of modern British history at Cambridge University, and the former Conservative chancellor Lord Lamont consider whether Keynes’s ideas were twisted by modern politicians to support their desires to run big spending deficits.”

Questions
- How is the recent crisis and recession similar to and different from the Great Depression of the inter-war period?
- Can recent fiscal policies adopted around the world be described as Keynesian?
- How would a government of a Keynesian persuasion attempt to manage the move from recession to economic growth and deal with the problem of mounting public-sector debt?
The early part of the current recession, dating from April 2008, had much in common with the Great Depression dating from June 1929. But the Great Depression lasted three years. So does this grim prospect await the world this time round? Or have we learned the lessons of the past and will the policies of giving economies a large fiscal stimulus, combined with bank rescues and quantitative easing, help to pull the world out of recession this year?
