The weak relationship between wage dynamics and unemployment in the euro area since the Global Crisis is widely perceived as one of the main causes of the ‘twin puzzle’ of missing disinflation between 2009 and 2011, and missing inflation thereafter. This column attributes the weak response of nominal wage growth to employment dynamics since 2008 to the countercyclical behaviour of labour productivity, which is driven, in turn, by the exceptionally high persistence of the downturn and the subsequent recovery.

Although long-term macroeconomic forecasts substantially affect the sustainability of government debt and the social security system, they cannot avoid significant uncertainty. This column assesses whether academic researchers in economics make accurate long-term growth forecasts, comparing ten-year growth forecasts made by Japanese economists in 2006–2007 with the realised figures. Even excluding the years affected by the Global Crisis, the results show that forecasts tend to be biased upwards and involve significant uncertainty, even for economics researchers specialising in macroeconomics or economic growth.

After the Global Crisis, accommodative monetary policy also eased financial conditions in emerging market economies. This column shows that US banks contributed to the transmission of US monetary policy and that regulation and supervision attenuated it. Only US banks that performed well in the Fed’s annual stress tests expanded their lending to emerging markets in response to monetary easing. Banks that performed poorly left their lending unchanged.

Over the past 30 years, euro area countries have undergone significant changes and endured diverse shocks. This column assembles a large set of variables covering the years 1990-2016 and investigates possible links to fluctuations and differences in growth rates. The findings suggest a significant positive role for institutional integration in supporting long-run growth, particularly for periphery countries. Competitiveness and monetary policy also matter for sustained growth in the long run, while higher sovereign stress, equity price cycles, loans to non-financial corporations and debt over GDP have either mixed or negative effects in core and periphery countries.

The ‘exchange rate disconnect’ describes the difficulty of explaining exchange rate movements using classical models and fundamentals. This column presents evidence of an ‘exchange rate reconnect’ – a substantial co-movement of the US dollar with global risk premia and US foreign bond purchases since the Global Crisis. Though short-lived, this relationship between these factors could shed new light on the nature of financial crises and risk.

For the last decade, euro area countries have undertaken substantial debt issuances in order to maintain or bolster international capital market access. This column shows that the ECB's unconventional monetary policy dampens yield cycles in secondary markets for euro area sovereign debt around new debt auctions. This dampening effect tends to be larger when market volatility is higher, and this can be used to minimise any instability generated, for example, by different countries’ issuances occurring close together or the spillover effects of one country’s auctions on another.

Real wages and productivity in the UK have stagnated since 2007, whereas employment has risen considerably. Many commentators lament the consequent failure of `living standards’ to rise at historical rates. But real GDP per capita has grown by more than 20% since 2000 despite the Great Recession, so aggregate living standards have in fact risen. This column resolves the apparent paradox.

Wage growth in the euro area over 2013 to 2017 was subdued despite notable improvements in the labour market, leading some to claim a breakdown of the output–inflation relationship. This column presents comparative analyses of wage developments in the euro area, showing that the Phillips curve is alive and well and can be used to explain much of the weakness in wage growth during 2013-2017. Other factors also found to have played a role include compositional effects, the possible non-linear reaction of wage growth to cyclical improvements, and structural and institutional factors.

What would happen if another crisis were to occur? In this video, Mario Monti discusses potential differences and challenges. This video was recorded at the "10 years after the crisis" conference held in London, on 22 September 2017.

Japanese exports in electronic parts and components dramatically fell in value after the Global Crisis and have not recovered until today. This column investigates why Japan lost this comparative advantage. It argues that capital inflows seeking safe havens during the crisis led to a sharp appreciation of the yen and caused yen export prices to tumble relative to production costs. Plummeting profits then hindered Japanese firms from investing enough in capital and innovation to compete with rivals.

During the Global Crisis, international trade decreased more than overall economic activity, despite standard trade models predicting a one-to-one relationship. This ‘Great Trade Collapse’ has been investigated extensively in the literature, resulting in alternative competing explanations. This column evaluates the contribution of each story using data from the US. The results show that retail inventories have contributed the most to the collapse and the corresponding recovery, followed by protectionist policies, intermediate-input trade, and trade finance. Productivity and demand shocks have played negligible roles.

Externalities can have a powerful effect on financial stability. This column studies the amplification effect that can operate despite value at risk regulation, which suffers from the ‘fallacy of composition’. It shows that the magnitudes of booms and busts are amplified by two significant externalities triggered by aggregate shocks: the endogeneity of bank equity due to mark-to-market accounting and of bank liquidity due to 'fire-sales' of securitised assets. In addition to economic models, legal and political factors should also be considered.

The ECB's unconventional monetary policy package implemented in February 2012 changed collateral requirements. This column examines the effects in the French credit market, using data on corporate loans. Credit indeed increased after the liquidity injection, exclusively driven by supply. There was also strategic risk-taking by a group of banks, an unintentional implication of the policy.

Academics and policymakers alike have debated how to structure an optimal stimulus package since the Great Recession. This column revisits the arguments related to the size of the multiplier and the usefulness of public spending, and offers a blueprint for future stimulus packages. It finds that the relationship between the multiplier and stimulus spending is hump-shaped, and that a well-designed stimulus package should depend on the usefulness of public expenditure. The output multiplier is not a robust statistic to use, and instead the ‘unemployment multiplier’ should be used.

Bank stress tests in the US were an important tool for bailing out banks in the Great Recession. As this column points out, however, because the tests use regulatory rather than market measures of asset values and risk they have almost nothing to do with whether a bank will be economically solvent under test conditions. This column argues that the thousands of pages of post-crisis bank regulation have largely ignored perhaps the two most needed reforms: measuring asset values and risks in an economically realistic way. Reforming the stress tests is necessary for clearly and credibly placing responsibility for future banking losses in the private sector and for improving incentives for both managing old risks and for investing in new ones.

Increasing protectionism will slow down world trade and may dampen global economic growth. This column examines the global macroeconomic consequences of a major trade conflict between the US and China, and shows that the two countries would be the biggest losers from a 10% ‘tit-for-tat’ trade war between them. As long as it does not get involved in the conflict, the euro area may temporally gain from trade diversion, as competitiveness improves and imports from regions whose exports are blocked elsewhere become cheaper.

Various factors have been advanced as possible causes of the build-up of risks leading to the Global Crisis, and multiple policies have been put forward to address them. This column discusses the effectiveness of monetary policy and macroprudential policy in responding to the build-up of risks in the financial sector. While both policies are useful, macroprudential policy is more effective in terms of financial stability and can lead to higher welfare gains.

The Global Crisis brought attention to how connections among financial institutions may make systems more prone to crises. Turning to a major financial crisis from the past, this column uses data from the Great Depression to study risk in the commercial banking network leading up to the crisis and how the network structure influenced the outcomes. It demonstrates that when the distribution of risk is more concentrated at the top of the system, as it was in 1929, fragility and the propensity for risk to spread increases.

The Global Crisis has profoundly changed the financial landscape, including firm financing. This column examines the development of various channels of firm financing before and after the crisis among four groups of EU countries, the US, and Japan. While bank finance and, to some extent, equity finance are under pressure, alternative finance, although small, seems to be on the rise.

There is little evidence on whether deteriorating household balance sheets in advanced economies have made monetary policy less effective since the Global Crisis. Using US household-level data, this column shows that the responsiveness of household consumption to monetary policy has in fact diminished since the crisis, and that households with the highest indebtedness responded the most to monetary policy shocks. Since the distribution of debt did not change after the crisis, this suggests that household debt did not contribute to lessening the effects of monetary policy over time.
