In the aftermath of the Global Crisis, international banking is undergoing structural adjustments. This column investigates the role of policy-related drivers of changes in cross-border bank lending since the Crisis. The findings indicate that changes in regulatory policies are important push and pull factors of foreign credit. The empirical evidence further suggests that expansionary monetary policy has helped alleviate credit market fragmentation to some extent.

The Great Recession was marked by disruptions to the supply of credit to firms and households. But little is known about how much supply shocks to household credit actually contributed to employment losses. This column uses data on US counties to examine the causal relationship running from the supply of household credit to employment during the recession. The author concludes that contractions in household credit supply caused substantial employment losses.

Researchers have put forward two explanations for the failure of the US inflation rate to fall as far during the Great Recession as the Phillips curve would predict. Either expectations have been successfully anchored by the Fed’s inflation target, or the Phillips curve is focusing on the wrong thing – aggregate unemployment instead of short-term unemployment. This column shows that the two explanations are complementary; together, they explain the puzzle, but separately they cannot.

Macroecomics has changed in a number of ways since the global crisis. For example, there is now more emphasis on modeling the financial sector, self-fulfilling panics, herd behaviour and the new role of demand. This Vox Talk discusses these changes as well as those areas in macroeconomics that are currently perhaps not researched enough. Wouter den Haan explains the inadequacy of the conventional 'rational expectations' approach, quantitative easing, endogenous risk and deleveraging and refers to current CEPR research that reflects the changes. He concludes by reminding us that the 'baby boomers' issue could be the basis of the next crisis.

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 post-Crisis G7 economies have suffered weak business investment despite record low interest rates and the favourable financial positions of corporates. Some consider this the ‘new normal’ arising from secular, supply-side forces that have contributed to declining potential growth rates. This column argues that structural factors alone are not sufficient to explain the current weakness in investment rates. There is thus room for positive surprise if companies realise the pent-up investment demand.

The appropriate level of public sector wages is debated frequently in every country, and the debate has intensified in the wake of the global financial crisis. This column presents evidence that regional wage differentials in Japan are greater in the private sector than in the public sector. In regions where public sector wages are relatively high, skilled individuals may self-select into public sector jobs. At the same time, public sector employers in metropolitan regions such as Tokyo may have difficulty in hiring high quality employees.

The past three years have witnessed a slowdown in global trade. This column shows that the slowdown was particularly pronounced in advanced economies, especially the Eurozone. In a panel of 18 OECD economies, most of the slowdown can be explained by cyclical factors. However, structural factors – global value chains and especially protectionism – may have played a role too.

In the aftermath of the Global Crisis, policymakers and academics alike discussed how uncertainty surrounding macroeconomic policymaking has impacted domestic investment. At the same time, concerns regarding the spillover impact of monetary policy in advanced economies on emerging market economies featured strongly in the international policy debate. This column draws the two debates together, and examines how policy uncertainty in advanced economies has spilled over to emerging markets via portfolio capital flows. It finds remarkable differences in the spillover effects of EU vs. US policy uncertainty.

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.

House price fluctuations take centre stage in recent macroeconomic debates, but little is known about their long-run evolution. This column presents new house price indices for 14 advanced economies since 1870. Real house prices display a pronounced hockey-stick pattern over the past 140 years. They stayed constant from the 19th to the mid-20th century, but rose strongly in the second half of the 20th century. Sharply increasing land prices, not construction costs, were the key driver of this trend.

There has been renewed interest in sovereign debt since the Global Crisis, but relatively little attention has been paid to its composition. Sovereign debt can differ in terms of the currency it is denominated in, its maturity, its marketability, and who holds it – and these characteristics matter for debt sustainability. This column presents evidence from a new dataset on the composition of sovereign debt over the past century in 13 advanced economies.

The reason for the divergent macroeconomic policies on the two sides of the Atlantic after the Crisis remains a hotly debated subject. The topic was also discussed at the recent “Macroeconomic Policy Mix in the Transatlantic Economy” workshop. This column summarises the main discussions at the workshop. Other covered topics included secular stagnation, the output effects of fiscal consolidation, cross-border banking (as a source and propagator of shocks), and the asset-market effects of unconventional monetary policies.

Following the Global Crisis the focus has been on how to make banks safer. Capital and liquidity requirements have been tightened, but attention now needs to shift to corporate governance and risk culture. This column argues that in opaque organisations, formal risk-appetite frameworks can provide a pre-commitment mechanism that tightens risk governance, but a focus on the wider risk culture is also important.

Regulation of the global insurance industry, an emerging challenge in international finance, has two central objectives: strengthening the oversight of insurance companies designated ‘systemically important’; and designing a global capital standard for internationally active insurers. This column argues that it is a Herculean task because the business model of insurance is less globalised than other areas in finance; because global regulators have less experience of insurance than banking where global standards have been pursued for a quarter of a century; and because, as yet, there is limited research-based understanding of the insurance business and its interactions with the financial system and the real economy. But in the aftermath of the global financial crisis and the AIG disaster, regulators are under strong pressure to make progress.

Despite the growth of online and card payments, the ratio of currency to GDP in the UK has been rising. This column argues that rapid growth in the grey economy has been a key cause. The authors estimate that the grey economy in the UK could have expanded by around 3% of UK GDP since the beginning of the Global Crisis.

Olivier Blanchard, Friday, October 3, 2014

Before the 2008 crisis, the mainstream worldview among US macroeconomists was that economic fluctuations were regular and essentially self-correcting. In this column, IMF chief economist Olivier Blanchard explains how this benign view of fluctuations took hold in the profession, and what lessons have been learned since the crisis. He argues that macroeconomic policy should aim to keep the economy away from ‘dark corners’, where it can malfunction badly.

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.

During the Great Moderation, inflation targeting with some form of Taylor rule became the norm at central banks. This column argues that the Global Crisis called for a new approach, and that the divergence in macroeconomic performance since then between the US and the UK on the one hand, and the Eurozone on the other, is partly attributable to monetary policy differences. The ECB’s model of the economy worked well during the Great Moderation, but is ill suited to understanding the Great Recession.
