The simple macroeconomics of North and South in EMU. Bruegel Working Paper 2012/12, 30 July 2012

The euro area today consists of a competitive, moderately leveraged North and an uncompetitive, over-indebted South. Its main macroeconomic challenge is to carry out the adjustment required to restore the competitiveness of its southern part and eliminate its excessive public and private debt burden. This paper investigates the relationship between fiscal and competitiveness adjustment in a stylised model with two countries in a monetary union, North and South. To restore competitiveness, South implements a more restrictive fiscal policy than North. We consider two scenarios. In the first, monetary policy aims at keeping inflation constant in the North. The South therefore needs to deflate to regain competitiveness, which worsens the debt dynamics. In the second, monetary policy aims at keeping inflation constant in the monetary union as a whole. This results in more monetary stimulus, inflation in the North is higher, and this in turn helps the debt dynamics in the South. Our main findings are: •The differential fiscal stance between North and South is what determines real exchange rate changes. South therefore needs to tighten more. There is no escape from relative austerity. •If monetary policy aims at keeping inflation stable in the North and the initial debt is above a certain threshold, debt dynamics are perverse: fiscal retrenchment is self-defeating; •If monetary policy targets average inflation instead, which implies higher inflation in the North, the initial debt threshold above which the debt dynamics become perverse is higher. Accepting more inflation at home is therefore a way for the North to contribute to restoring debt sustainability in the South. •Structural reforms in the South improve the debt dynamics if the initial debt is not too high. Again, targeting average inflation rather than inflation in the North helps strengthen the favourable effects of structural reforms.

Focal points and fiscal discipline. ACES Cases No. 2013.2

Many studies suggest that balanced budget rules can restrain sovereign debt and lower sovereign borrowing costs, even if those rules are never enforced in court. Typically, this is explained as a result of a legal deterrence logic, in which the threat of judicial enforcement deters sovereigns from violating the rules. By contrast, we argue that balanced budget rules work by coordinating decentralized punishment of sovereigns by bond markets, rather than by posing a credible threat of judicial enforcement. Therefore, the clarity of the focal point provided by the rule, rather than the strength of its judicial enforcement mechanisms, determines its effectiveness. We develop a formal model that captures the logic of our argument, and we assess this model using data on US states. We then consider implications of our argument for the impact of the balanced budget rules recently imposed on eurozone states in the Fiscal Compact Treaty.

Did the German court do Europe a favor? Bruegel Working Paper 2014/09, July 2014

The European Central Bank’s Outright Monetary Transactions (OMT) programme was a politically-pragmatic tool to diffuse the euro-area crisis. But it did not deal with the fundamental incompleteness of the European monetary union. As such, it blurred the boundary between monetary and fiscal policy. The fuzziness of this boundary helped in the short-term but pushed political and economic risks to the future. Unless a credible commitment to enforcing losses on private creditors is instituted, these conundrums will persist. The German Federal Constitutional Court has helped by insisting that such a dialogue be conducted in order to achieve a more durable political and economic solution. A study of the European Union Court of Justice’s Pringle decision (Thomas Pringle v Government of Ireland, Ireland and The Attorney General, Case C-370/12, ECJ, 27 November 2012) suggests that the ECJ will also not rubber-stamp the OMT – and, if it does, the legal victory will not resolve the fundamental dilemmas.
