The feedback loop between banking crises and sovereign debt crises has been at the heart of recent problems in the Eurozone. This column presents stylised facts on the mechanisms through which banking and sovereign crises combine and become ‘twin’ crises. The results point to systematic differences not only between ‘single’ and ‘twin’ crises, but also between different types of ‘twin’ episodes. The timing of ‘twin’ crises – which crisis comes first – is important for understanding their drivers, transmission channels, and economic consequences.

There has been a long-term downward trend in labour’s share of national income, depressing both demand and inflation, and thus prompting ever more expansionary monetary policies. This column argues that, while understandable in a short-term business cycle context, this has exacerbated longer-term trends, increasing inequality and financial distortions. Perhaps the most fundamental problem has been over-reliance on debt finance. The authors propose policies to raise the share of equity finance in housing markets; such reforms could be extended to other sectors of the economy.

The role of credit-fuelled property booms in the Global Crisis has received much high-profile attention in recent years. Using data on Irish small and medium enterprises, this column highlights an additional channel through which such booms can impact post-crisis growth. Firms having difficulty repaying their property-related debts divert resources away from hiring and investment. Property booms thereby induce misallocation of resources in both the boom and the bust.

Real interest rates have fallen to historic lows, and some economists are concerned that an era of secular stagnation has begun. This column highlights the role of policy frameworks and financial factors – particularly debt – in linking low real interest rates and sluggish economic growth. Policies that do not lean against booms but ease aggressively and persistently in busts induce a downward bias in interest rates over time and an upward bias in debt levels – something akin to a debt trap. Low real interest rates may thus be self-reinforcing and not always ‘natural’.

The debt-growth link is essential to today's marcoeconomic policy choices. This Vox Talk discusses new evidence based on data on total public debt for 105 economies between 1972 and 2009 and two centuries of data for the UK, US, Sweden and Japan. There is no convincing proof that austerity works and that it is dangerous for policy makers to pretend otherwise.

Stijn Claessens talks to Viv Davies about the recent IMF book titled 'Global Crises: Causes, Consequences and Policy Responses', co-edited with M Ayhan Kose, Luc Laeven, and Fabian Valencia. The book provides a comprehensive overview of current research into financial crises and the policy lessons learned. They discuss crisis prevention and management, and the crisis in the Eurozone. The interview was recorded in April 2014.

The recent debate on the link between austerity and growth has focused on the short run. This column discusses recent research into the link between fiscal consolidation and medium-term growth under different financial conditions. If credit is not available to consumers and investors, private demand is less able to compensate for cutbacks in public demand, so large spending cuts can have a negative effect on growth. Difficult financial conditions probably explain why fiscal adjustments that worked in the 1990s have not produced similar beneficial effects on growth in recent years.

Although progress has been made on resolving the Eurozone crisis – vulnerable countries have reduced their current-account deficits and implemented some reforms – more still needs to be done. This column argues for a ‘consistent trinity’ of policies: structural reforms within countries, more symmetric macroeconomic adjustment across countries, and a banking union for the Eurozone.

Sales of state-owned assets have been proposed as a way for highly-indebted countries to ease the pain of fiscal consolidation. This column argues that, despite the potential merits of privatisation in terms of long-run efficiency, in practice it is unlikely to improve short-run fiscal solvency. Since governments rarely alienate control rights, the efficiency gains from privatisations are often small. Moreover, financial markets may not fully reflect these gains – particularly during a financial crisis. The implication is that the Troika policy of linking financial assistance to privatisations is inappropriate and self-defeating.

One popular explanation for the increase in US household debt in the years before the subprime mortgage crisis is that households with stagnating incomes borrowed more to ‘keep up with the Joneses’. This column presents recent research that questions this explanation. Low-income households in high-inequality regions in fact borrowed relatively little compared to similar households in low-inequality regions. A theoretical model in which greater local income inequality facilitates the screening of loan applicants makes predictions that are consistent with the data.

Democratic governments tend to accumulate excessive debt. This column proposes a new rule – the ‘Catenarian Fiscal Discipline’ – which allows a fiscally disciplined incumbent to limit the debt-making of the next officeholder. This way, fiscal discipline today can lead to fiscal discipline in the future. Such a rule would require that we broaden our notion of representative democracy by recognising the fact that a current government already has various implicit ways of limiting what its elected successors can do.

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.

Alberto Alesina, Friday, November 30, 2012

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.
