Dynamic stochastic general equilibrium models are still dominant in mainstream macroeconomics, but they are only able to explain business cycle fluctuations as the result of exogenous shocks. This column uses concepts from behavioural economics to develop macroeconomic models with endogenous business cycle fluctuations. Application of the models highlights how the trade-off between output and inflation is moderated by the flexibility of the economy. The models further help to explain the international transmission of business cycle fluctuations.

In many economies, inflation may have remained stubbornly low during the recovery because their Phillips curves have become flatter. This column uses an analysis of Swiss data since 1916 that support this argument. The most recent structural break in the Swiss Phillips curve occurred in 1994, when it became much flatter. Previous structural breaks suggest that this has been a change from an above-average to a below-average slope, not a collapse from the long-term normal level.

Determining ‘currency value’ is a century-old topic on which there is little consensus among economists. This column proposes a novel way of adjusting real exchange rates for key country-specific fundamentals to obtain better gauges of currency valuation levels. Adjusting for productivity, export quality, foreign assets, and output gaps is shown to isolate information related to currency risk premia across countries. This can serve as a more precise input into investment and policy decisions.

Olivier Blanchard and Daniel Leigh’s work on growth forecast errors and fiscal multipliers in 2009-2011 has been highly influential. This column extends their approach to recent years. The authors do not find convincing evidence for stronger-than-expected fiscal multipliers for EU countries during the sovereign debt crisis (2012-2013) or during the tepid recovery thereafter.

Stagnation is gripping several of the world’s largest economies and many view this as secular, not transient. This column argues that many economies need both demand-side stimulus and supply-side reform to close the output gap and restore potential-output growth. A combined monetary-fiscal stimulus – i.e. helicopter money – is needed to close the output gap, and this should be accompanied with extensive debt restructuring, policies to halt rising inequality, and additional public infrastructure investment.

Fears that the financial crisis will have a significant negative impact on long-term UK economic growth are unfounded, according to a majority of the UK macroeconomics profession surveyed by the Centre for Macroeconomics (CFM). What’s more, the inaugural CFM survey, summarised in this column, indicates some optimism about the UK’s immediate capacity for higher growth: while roughly half of the respondents share the views of the Office of Budget Responsibility, the other half is substantially more optimistic about the capacity for the economy to recover.
