During the Global Crisis, sovereign debt-to-GDP ratios grew substantially in the face of shocks to growth, increased fiscal deficits, bank recapitalisation costs, and rising borrowing costs. This column looks at how these various shocks interact with each other to exacerbate or mitigate the eventual impact on debt. Choice of monetary policy regime is an important determinant of how public debt reacts to these shocks.

Bankers’ compensation has been indicted as a contributing factor to the Global Crisis. The EU and the US have responded in different ways – the former legislated bonus caps, while the latter implemented bonus deferrals. This column examines the effectiveness of these measures, using US data from just before the Crisis. Caps are found to be more effective in reducing the risk-taking by bank CEOs.

Despite being a mainstay of macroeconomic theory for the past half century, the Phillips curve often receives the death knell from various commentators. These critiques often rely on results from data samples spanning relatively short periods. Using the case of Ireland, this column argues that short-term idiosyncrasies can explain the failure of the model in these contexts. Taking a longer historical view, the Phillips curve remains a useful macroeconomic model, at least in the Irish context.

The financial crisis brought with it many challenges, both to prevailing disciplinary tenets, and for research and policy more generally. This column outlines the lessons that can be drawn from the financial crisis – issues like financial market failures, macro-prudential policy, structural changes of the financial system, and the European banking union. It argues for the inclusion of these topics in curricula for the next generation of finance students.

The story of the run-up to the Global Crisis is, unfortunately, not an entirely new one. This column argues that regulators would do well to read up on the ‘Panic of 1907’. What quelled rumours and panicky behaviour back then still applies – maintaining market liquidity through measures that encourage transparency.

The 2007–08 crisis revealed regulatory failures that had allowed the shadow banking system and systemic risk to grow unchecked. This column evaluates recent proposals to reform the banking industry. Although appropriate pricing of risk should make activity restrictions redundant, there may nevertheless be complementarities between these two approaches. Ring-fencing may make banking groups more easily resolvable and therefore lower the cost of imposing market discipline.

In the wake of the Great Recession, a contentious debate has erupted over whether austerity is helpful or harmful for economic growth. This column compares the experiences of the East Asian countries – whose leaders responded to the East Asian financial crisis with expansionary fiscal policy – with those of the European periphery countries during the Great Recession. The authors argue that it was a mistake for the European periphery countries to pivot from fiscal expansion to consolidation before their economies had recovered.

The corporate cash ratio – the share of liquid assets in total assets – comoves with employment in the US. This column argues that disentangling liquidity shocks and credit shocks is key to understanding this comovement, and that liquidity shocks appear to be crucial. These shocks make production less attractive or more difficult to finance, while they also generate a need for internal liquidity to pay wages, which can be satisfied by holding more cash.

A number of US studies have found a link between high pre-crisis debt and weak consumption after the recent financial crisis. This column investigates the relationship between household debt and consumption in the UK. Spending cuts associated with debt are estimated to have reduced the level of aggregate private consumption by around 2% after 2007, unwinding the faster growth in spending by highly indebted households, relative to other households, before the financial crisis.

Banking has recently proven much more fragile than expected. This column argues that the Basel III regulatory response overlooks the interactions between different kinds of prudential policies, and the link between prudential policy and competition policy. Capital and liquidity requirements are partially substitutable, so an increase in one requirement should generally be accompanied by a decrease in the other. Increased competitive pressure calls for tighter solvency requirements, whereas increased disclosure requirements or the introduction of public signals may require tighter liquidity requirements.

Since the Global Crisis, concerns have grown that advanced economies are suffering from secular stagnation. This column discusses the lessons that can be learnt from the economic transition of central and eastern Europe and the emerging-market crises of the late 1990s and early 2000s. Structural reform is particularly costly in the context of a debt overhang and an overvalued exchange rate. However, the crux is not debt restructuring per se, but whether economic governance changes credibly for the better following it.

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.

World War I profoundly altered the structure of the US economy and its role in the world economy. However, this column argues that the US learnt the wrong lessons from the war, partly because a halo of victory surrounded wartime policies and personalities. The methods used for dealing with shortages during the war were simply inappropriate for dealing with the Great Depression, and American isolationism in the 1930s had devastating consequences for world peace.

The prevailing view of shadow banking is that it is all about regulatory arbitrage – evading capital requirements and exploiting ‘too big to fail’. This column focuses instead on the tradeoff between economic growth and financial stability. Shadow banking transforms risky, illiquid assets into securities that are – in good times, at least – treated like money. This alleviates the shortage of safe assets, thereby stimulating growth. However, this process builds up fragility, and can exacerbate the depth of the bust when the liquidity of shadow banking securities evaporates.

Central banks have resorted to various unconventional monetary policy tools since the onset of the Global Crisis. This column focuses on the macroeconomic effects of the Federal Reserve’s large-scale purchases of mortgage-backed securities – in particular, through reducing the ‘mortgage spread’ between interest rates on mortgages and government bonds at a given maturity. Although large-scale asset purchases are found to have substantial macroeconomic effects, they may not necessarily be the best policy tool at the zero lower bound.

Since the Global Crisis, critics have questioned why regulatory agencies failed to prevent it. This column argues that the US Federal Reserve was aware of potential problems brewing in the financial system, but was largely unconcerned by them. Both Greenspan and Bernanke subscribed to the view that identifying bubbles is very difficult, pre-emptive bursting may be harmful, and that central banks could limit the damage ex post. The scripted nature of FOMC meetings, the focus on the Greenbook, and a ‘silo’ mentality reduced the impact of dissenting views.

Financial crises are often credit booms gone bust. This column argues that ‘political booms’, defined as an increase in government popularity, are also a good predictor of financial crises. The phenomenon of ‘political booms gone bust’ is, however, only observable in emerging markets. In these countries, politicians have more to gain from riding the popularity benefits of unsustainable booms.

Since the Global Crisis, support has grown for the use of time-varying capital requirements as a macroprudential policy tool. This column examines the effect of bank-specific, time-varying capital requirements in the UK between 1990 and 2011. In response to increased capital requirements, banks gradually increase their capital ratios to restore their original buffers above the regulatory minimum, reducing lending temporarily as they do so. The largest effects are on commercial real estate lending, followed by lending to other corporates and then secured lending to households.

The European Monetary Union is unprecedented, but the Eurozone Crisis is not. This column draws upon the experiences of previous banking crises, and compares the Eurozone Crisis countries. Like Japan before the 1992 crisis, Spain and Ireland had property bubbles fuelled by domestic credit. The Greek crisis is very distinct from crises in other Eurozone countries, so a one-size-fits-all policy would be inappropriate. The duration and severity of past crises suggest the road ahead will continue to be very rough.

Wendy Carlin talks to Viv Davies about the 'Curriculum Open-access Resources in Economics' (CORE) project, which was established by the Institute for New Economic Thinking (INET) at Oxford and proposes a new approach to economics teaching for undergraduates. The aim is to update the existing economics curriculum so that it reflects recent developments in economics, the economy and in teaching methods. They discuss the 'three gaps' in economics teaching that the project seeks to close. The interview was recorded in April 2014 at the annual conference of the Royal Economic Society.
