I recently wrote a paper with Jerome Creel and Paul Hubert, in which we try to assess the impact of the different fiscal rules that are being discussed for reforming the Eurozone governance. For our simulations we took into account the standard Keynesian positive effects of deficit spending: Government expenditure substitutes missing private demand, and hence supports economic activity. But we also embedded a negative effect of deficit and debt, that goes through increased interest rates (the famous spreads). High interest rates make it harder for the private sector to finance spending, and hence depress aggregate demand and growth. We assessed the performance of the rules in terms of average growth over the next 20 years.
A couple of years ago (February 2010), I thought I was being really heterodox, when I argued that Greece should be given 7-8 year to consolidate its public finances, because any sharp consolidation plan would push it into recession. The interview was in French, but more or less I said that
Not surprisingly, the deal reached last week failed to put the EMU economies back on track. I have always looked with suspicion, if not with outright fear, to policy agendas dictated by financial markets. But the fact that a simple attempt by the Greek Prime Minister to involve his fellow citizens in crucial decisions is creating a panic attack, shows how fragile the agreement was. With André Grjebine I wrote a piece for the French daily Liberation last week, in which we argued that all the crucial weaknesses of the Eurozone were not addressed.
- Address current account imbalances symmetrically, along the lines already outlined by Keynes before Bretton Woods.
- Focus more on quality of public spending, and not on quantitative targets. We mention the golden rule in its original meaning, i.e. the exclusion of public investment from numerical deficit targets. A study (working paper here) I made with some colleagues a while ago hinted that it worked for the UK.
- Finally, we insisted on debt monetization by the ECB, the only possible strategy to defuse speculation against sovereign debt of a currency union.
