The idea that there is a common tipping point in the relationship between public debt and economic growth is still widespread. However, this is likely due to a misinterpretation of the existing evidence. Once we allow for the relationship between debt and growth to be country-specific, there is limited evidence supporting the presence of a within-countries debt threshold.

In the debate over Scottish independence, the question of how the UK’s assets and sovereign debt would be divided has received insufficient attention. This column argues that the size of Scotland’s debt obligations would be crucial to its optimal choice of currency. Under plausible assumptions, fiscal tightening would be required to return Scottish debt to sustainable levels, and a self-fulfilling rise in borrowing costs might tempt Scotland to leave the sterling currency union. A debt-for-oil swap might be mutually beneficial for a newly independent Scotland and the continuing UK.

In the aftermath of the global financial crisis, few would dispute the risks of excessive borrowing. But which debts should one worry about – public or private? This column presents new research on the interplay of public and private debts since 1870 in 17 advanced economies. History demonstrates that excessive private-sector borrowing plays a greater role than fiscal profligacy in generating financial instability. However, when the credit boom collapses, the government’s capacity to alleviate the downturn is limited by the prevailing level of public debt.

The IMF loans to Greece, Ireland and Portugal are considered controversial by some analysts. This column argues that these loans – granted without having agreed on convincing paths to manageable debt levels – constituted a substantial departure from IMF principles. The situation is costly for Europe and, having now permanently changed the principles guiding large IMF loans, it will be costly for crises to come. A serious rethink of the management and decision-making structure of the IMF is needed.

Should we expect more global financial crises? This column argues that we should. Global financial crises are far from being a thing of the past because they are often caused by buildups of excessive domestic and foreign debt. To successfully address them and to limit negative spillovers, we need coordinated actions that prevent a contraction in global liquidity. Unless we establish this more robust, coordinated global financial safety net centred on central banks (which is where the money is), we may end up being incapable of addressing inevitable future crises.

Debt seems to be a lightning rod for crises. This column presents new research showing that the ratio of net foreign liabilities to GDP, and in particular its net external debt component, is indeed a significant crisis predictor for both advanced economies and emerging markets. Large current-account deficits and real exchange rate appreciation – the standard predictors – still matter, but we should be thinking more about net external debt.

Are Eurobonds a desirable solution to Eurozone members’ debt crises? Unhappily, it’s difficult to say. This column argues it very much depends on how the system is designed. However, looking at the most prominent proposals, it seems a cleverly designed Eurobonds system may well provide governments with the right incentives to encourage both issuing less debt and pursuing meaningful structural reform.

Five years after the subprime bubble burst, the self-correcting nature of business cycles is being questioned and, subsequently, orthodox macroeconomic policy is starting to be challenged. This column introduces a radical rethink of options open to macroeconomic policymakers, suggesting that in order to simultaneously achieve economic stimulus without increasing debt, new money creation should be used to directly finance on-going budget deficits.

Should debt-ridden and economically struggling Western governments be doing everything possible to reduce their deficits? Should we cut spending or hike taxes to reduce our debt-to-GDP ratios? This column argues that the answer is obvious: the cheapest, most effective and confidence-inspiring route is to cut spending. Coupled with other pro-growth policies, the evidence suggests that it is only really spending cuts that will spur private investment and economic recovery in Europe.

Booming commodity prices generate large foreign currency inflows for exporting nations. This column argues that in countries with executive constraints and political competition windfalls from commodity booms lead to a significant reduction in external debt. In autocratic regimes, on the other hand, the windfalls are used to increase consumption expenditures.

Rich nations worldwide have a problem with debt. In the past, such problems have been dealt with by several tactics, including 'financial repression'. This column explains how the tactic works and documents its resurgence in the wake of the global and Eurozone crises.

As fiscal-consolidation policies are being implemented across the EU, a debate has been developing concerning the effects of such policies on the dynamics of the debt-to-GDP ratio. This column examines past episodes and finds that following fiscal adjustment may have favourable effects in the short term but that the two-year cumulated changes have been mainly adverse.
Carmen M Reinhart, Monday, January 9, 2012
Financial crises often unfold according to common patterns, but the post-2007 contraction is in fact different from other post-WWII crises in its unusual severity, says Carmen Reinhart in CEPR DP8742. But the patterns of past crises may still provide clues on the future of housing, labour, and international financial markets. This paper outlines what that future might look like.

Why do governments repay external borrowing? This column argues that myopic governments seeking popularity do not default when they are poor because they would lose access to debt markets and be forced to reduce spending. And they do not default when rich because of the adverse consequences to the domestic financial sector. This explains why governments continue servicing debt when default is beneficial for the country.

Europe’s debt crisis is unfolding while Japanese and US debt problems are on hold. The problem of public debt in advanced economies will be with us for decades. This column introduces a new Geneva Report on the World Economy that addresses the nuts, bolts, and worries surrounding the issue.

The 13th CEPR/ICMB Geneva Report on the World Economy takes a long-term perspective on debt sustainability, arguing that fiscal stabilisation is easier the faster the economy is growing.
Carmen M Reinhart, Kenneth Rogoff, Monday, March 28, 2011
With public debt in the US higher than it's been since 1945 and private debt burgeoning, governments are panicking about the impact of debt overhang on growth. In CEPR DP8310, Reinhart and Rogoff argue that governments have increasingly resorted to undercover restructuring by using the tools of "financial repression" that characterized the Bretton Woods era. If states continue to ignore or distort their debt problems, the authors predict, their bond markets could become ever more repressed.

Commentators have recently floated the possibility of debt buybacks as a way of reducing a country's debt, particularly in the crisis-ridden Eurozone. Are buybacks a good idea? This column argues that, while there could be some circumstances in which debt buybacks are efficient, theory and experiences suggest that buybacks are generally costly and inefficient, and in practice (concerted) debt exchanges have been preferred.

Record levels of government debt in the EU have forced some countries to call for help. This column presents data from the EU between 1985 and 2009 covering episodes when governments have tried to rapidly lower public debt. It shows that appropriate policies, especially on the expenditure side, can help make this reduction sustainable.
Paul Krugman, Thursday, November 18, 2010
Debt is the crux of advanced economies’ current policy debates. Some argue for fiscal expansion to avoid recession and deflation. Others claim that you can’t solve a debt-created problem with more debt. This column explains the core logic of a new model by Eggertsson and Krugman in which debt shocks and policy reactions can be examined. Relying on heterogeneous agents, the model naturally produces the paradox of thrift but also finds new supply-side paradoxes, those of toil and flexibility. The model suggests that most economists have been misthinking the issues and that actual policy in the US and EU is misguided.
