Recent economic events cast doubt on the standard macroeconomic models. This column looks at new economic models built on the idea that inequality and income risk matter for the business cycle and long-run outcomes. While still in their infancy, these models show promise in addressing the concerns about the old New Keynesian models, and in bringing about a shift in the way that macroeconomists think about aggregate fluctuations and stabilisation policy.

Globalisation is in retreat, but while the slowdown in trade is widely recognised, what is more striking is the collapse of global trade flows. This column shows how banking deglobalisation is a substantial contributor to the sharp slowdown in global capital flows. It finds that certain types of unconventional monetary policy, and their interactions with regulatory policy, can have important global spillovers. Policies designed to support domestic lending may have had the unintended consequence of amplifying the impact of microprudential capital requirements on external lending.

An efficient allocation of inputs across firms is a necessary condition to boost TFP growth. This column presents evidence that in large Eurozone economies, capital misallocation trended upwards in the period 2002-2012 while labour misallocation dynamics were flatter. Uncertainty and credit market frictions were strongly associated with the observed developments in capital misallocation, whereas the overall deregulation in the product and labour markets contributed to dampening input misallocation dynamics.

As with previous systemic crises, the 2007-2009 crisis has created regulatory reform, but is it adequate? This column argues that prudential regulation should consider interactions between conduct – capital, liquidity, disclosure requirements, macroprudential ratios – and structural instruments, and also coordinate with competition policy. Though recent reforms are a welcome response to the latest crisis, we do not know how effective they will be in future.

In the wake of the Great Recession, the Federal Reserve took unprecedented measures to stem economic decline. This column uses the Fed’s open-market operations in 1932, another period of short-term rates near the zero lower bound, as a comparison for the QE1 operation of 2008-09. Although the 1932 policy boosted output and inflation, if the Fed had announced the operation in advance and carried it out for a full year, the Great Depression could have been attenuated considerably earlier.

After the 2008 Global Crisis, there has been progress towards a system-wide regulatory architecture that includes a national macroprudential authority. This column describes a ‘capacity indicator’ that measures the state of macroprudential policies worldwide, including the features policymakers believe constitute a successful macroprudential policy regime. Eventually this index may be used to establish whether these macroprudential policy innovations have been successful.

Over the past two years, a significant disinflationary impulse has dampened nominal activity around the world. As this disinflationary impulse fades, however, both nominal and real growth should normalise. Indeed, as this column highlights, the latest signs show inflation and inflation expectations rising, profits stabilising, and capital expenditure inching up.

Banks' payout decisions at the beginning of the financial crisis of 2007-2009 were particularly controversial as the crisis eroded the capital of many banks. Concerns were raised that banks may have engaged in wealth transfer to shareholders, or that they may have been reluctant to reduce dividends to avoid negative signalling. This column examines these arguments using a large dataset on US bank holding companies. Cross-sectional tests do not provide clear-cut evidence of active wealth transfer. Similarly, the evidence on signalling is mixed.

Conventional wisdom on supply and demand suggests that demand shocks are cyclical or transitory, and that only technology shocks are responsible for trend changes. This column argues that cyclical events can have permanent effects on demand, and therefore GDP. It is time for policymakers to start considering the possibility of hysteresis seriously.

The Great Recession has had long-lasting effects on credit markets, employment, and output. This column combines a model with macroeconomic data to measure how the recession has changed beliefs about the possibility of future crises. According to the model, the estimated change in sentiment correlates with economic activity. A short-lived financial crisis can trigger long-lived shifts in expectations, which in turn can trigger secular stagnation.

Structural reforms can have adverse effects in the short run if implemented under weak macroeconomic conditions. This column argues that prioritising reform measures that bring short-term benefits even in a bad conjuncture, and packaging them to benefit from reform complementarities across product and labour markets, remains the most promising growth strategy, especially in the post-Global Crisis context

The fragmentation of financial systems along national borders was one of the main handicaps of the Eurozone both prior to and in the initial phase of the crisis, hindering the shock absorption capacity of individual member states. The EU has taken important steps towards the deeper integration of Eurozone financial markets, but this remains incomplete. This column argues that a fully-fledged financial union can be an efficient economic shock absorber. Compared to the US, there is significant potential in terms of private cross-border risk sharing through the financial channel, more so than through fiscal (i.e. public) means.

Much of the damage from the Great Recession is attributed to the Federal Reserve’s failure to rescue Lehman Brothers when it hit troubled waters in September 2008. It has been argued that the Fed’s decision was based on legal constraints. This column questions that view, arguing that the Fed did have the legal authority to save Lehman, but it did not do so due to political considerations.

Fiscal multipliers tend to be larger when the fiscal position of governments is stronger. This column argues that the link between fiscal multipliers and fiscal positions is independent of the business cycle. Although multipliers are generally larger in recessions, they are smaller during times of high debt, even during recessions, relative to what they would be if government debt were lower.

Econophysics is an emerging field applying theories and methods from physics to economic problems and data. This column explores the collective motions of trade and the effects of trade liberalisation, using global data from the past two decades. Econophysics methods reveal how business cycles synchronise, and how economic risk propagates throughout the global economic network. The results also highlight inherent problems of structural controllability that are induced during economic crises.

Finance plays a key role in growth by connecting savers and investors, but it can also be a source of crises. This column discusses whether there has been enough finance to enable productive investments. UK non-financial companies appear to have enough internal funds to cover all their investment taken as a whole, but the evidence suggests that small firms face shortfalls. The column also pleads for the development of new and better data sources to help measure the supply of finance that can be used to exploit productive investment opportunities.

The US government’s ‘bailout of bankers’ in 2008-09 remains a highly controversial moment in economic policy. Many critics suggest that intervention to relieve household debt may have been more effective in stimulating economic recovery. This column suggests that without federal intervention to stabilise financial markets and recapitalise some non-bank lenders, the magnitude of the economic collapse might have been much worse. While household debt was incredibly important in reducing demand, the financial sector dislocations and the lack of credit also played a critical role.

During normal operations, price discovery is an important feature of decentralised market trading. But the process can be distorted when markets are under great stress, such as during the run up to the collapse of Lehman Brothers in 2008. This column uses trading data from the days leading up to and following the collapse to show that price discovery at US stock exchanges remained remarkably efficient, even at the height of the turmoil.

Since the Global Crisis, interest rates in many advanced economies have been low and, in many cases, are expected to remain low for some time. Low interest rates help economies recover and can enhance banks’ balance sheets and performance, but persistently low rates may also erode the profitability of banks if they are associated with lower net interest margins. This column uses new cross-country evidence to confirm that decreases in interest rates do indeed contribute to weaker net interest margins, with a greater adverse effect when rates are already low.

The success of independent central banks is often used to argue in favour of independent fiscal councils with the aim of promoting sound fiscal policies. But unlike central banks, fiscal councils have no policy levers to pull – they can bark but never bite. This column explores the theoretical foundations and practical implications of fiscal councils. The evidence suggests that independent councils can mitigate the deficit bias. They do this by subjecting the ‘fiscal alchemy’ to systematic, rigorous, and highly publicised scrutiny.
