Many establishments both hire and lay off within a short time window, resulting in ‘churn’. This column uses a newly constructed dataset to show that the rate of churn in Germany is high and can be up to 40% greater in booms compared to recessions. Both establishments that are shrinking and those that are growing hire more and lay off more in booms than in recessions.

Business cycle stabilisation policy in the Eurozone may end up being far from optimal if member states must tighten fiscal policy amid weak economic activity while monetary policy is constrained by the lower bound on nominal interest rates. This column surveys the recent literature formulating practical lessons for the Eurozone’s ability to implement an effective monetary–fiscal policy mix.

Emerging economies, particularly those dependent on commodity exports, are prone to highly disruptive economic cycles. This column points to fluctuations in international commodity prices as a key driver of these cycles. Using a small open economy model, it quantitatively assesses their importance for Argentina’s economy, and finds that they explain 38%, 42%, and 61% of the variance of output, consumption and investment growth, respectively.

The debate about the future of the Economic and Monetary Union entails a careful examination of the costs and benefits of the European single currency. This column takes stock of the empirical evidence on the euro’s effects on business cycle synchronisation. We find that synchronisation across European countries increased by 50% after 1999 (the year the euro was introduced) and that this increase was more pronounced in euro area countries.

This column presents the first bi-annual report from CEPR’s Euro Area Business Cycle Dating Committee on the state of the Eurozone business cycle. The main findings are that the Eurozone expansion is continuing slowly, but is creating employment at a rapid pace; the recovery is commensurate with the US recovery once the Eurozone’s double-dip sovereign debt recession is factored in; and the heterogeneity in the pace of recovery of individual member countries is driven by the heterogeneity in their recessions.

Exchange rates are important contributors to business cycle fluctuations in open economies. Forecasting exchange rates is not an easy task, however, perhaps due to the instability of their relationship with economic drivers. This column introduces a model that also allows for changing volatility when forecasting exchange rates. Modelling time variation in the cross-rate relationships, and in the volatilities of the shocks hitting the economic system, significantly improves forecasts.

In September 2016, the ECB held its first Annual Research Conference. This column surveys the contributions to the conference, which brought together policymakers and academics from around the world to promote discussion of topics at the forefront of monetary and financial economic research. Nobel laureate Eric Maskin gave the keynote lecture, addressing whether fiscal policy should be set by politicians, and the conference included eight further presentations and a panel discussion on monetary policy and financial stability.

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

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.

There is a high degree of correlation between the business cycles of different countries. This is particularly the case in the Eurozone, but also among industrialised countries outside of the Eurozone. Using a two-country behavioural macroeconomic model, this column shows that the main channel for the synchronisation of business cycles is the propagation of ‘animal spirits’ – waves of optimism and pessimism that become correlated internationally.

There seems to be a robust consensus that the relationship between the countries in the EU that use the euro as their currency (‘euro-ins’) and those that do not (‘euro-outs’) is the most important of the four areas in the ‘new settlement’ between the UK and the EU. This column presents new econometric estimates showing that, after the introduction of the euro, the UK and Eurozone business cycles became significantly more synchronised. It is likely this upsurge in synchronisation increased the costs of a potential UK exit from the EU.

The interaction of incomplete markets and sticky nominal wages is shown to magnify business cycles even though these two features – in isolation – dampen them. During recessions, fears of unemployment stir up precautionary sentiments which induces agents to save more. The additional savings may be used as investments in both a productive asset (equity) and an unproductive asset (money). But even a small rise in money demand has important consequences. The desire to hold money puts deflationary pressure on the economy, which, provided that nominal wages are sticky, increases wage costs and reduces firm profits. Lower profits repress the desire to save in equity, which increases (the fear of) unemployment, and so on. This is a powerful mechanism which causes the model to behave differently from both its complete markets version, and a version with incomplete markets but without aggregate uncertainty.

In the past few years, the world has witnessed large swings in world relative prices, from oil, to metals, to food prices. This column examines how important these terms-of-trade shocks are in explaining GDP fluctuations. Using structural vector autoregression analysis, it shows that terms-of-trade shocks account for no more than 10% of business-cycle fluctuations in the majority of poor and emerging countries.

There is no consensus on the effectiveness of government spending as a measure for boosting output. This column suggests that increasing government spending is highly effective exactly when it is most needed – when the economy is experiencing a deep recession. But the finding does not imply a one-size-fits-all recommendation. There are potential dangers in increasing spending in countries whose level of debt might be perceived as unsustainable.

A large literature in macroeconomics shows how credit market shocks can propagate through deterioration in the value of collateral. This column decomposes debt into secured and unsecured components and investigates their effects separately. While secured debt is acyclical, unsecured debt is confirmed to predict GDP movements in accordance with the standard financial accelerator mechanism.

The Global Crisis has forced a revaluation of the standard macroeconomic models in use worldwide. This column discusses an enrichment that include a formal concept of ‘confidence’ about the short-medium term economic outlook – one that relates to market psychology rather than expectations about technology and policy. This extension helps the model predictions better match reality. It also offers a formalisation of the popular view that depressed spending, arising from a drop in confidence, is a major cause of recessions and that recoveries often hinge on ‘restoring confidence in the economy’.

The CEPR Business Cycle Dating Committee recently concluded that there is not yet enough evidence to call a business cycle trough in the Eurozone. Instead, the committee has announced a 'prolonged pause' in the recession. This Vox Talk discusses the possible directions that this situation could lead to and questions whether the Great Recession has harmed the Eurozone’s long-term growth prospects to the extent that meagre growth could become the 'new normal'.

CEPR CEPR Business Cycle Dating Committee, 17 June 2014

The simplest business cycle dating algorithm declares recessions over after two consecutive quarters of positive GDP growth. By that metric, the Eurozone recession has been over since 2013Q1. This column argues that growth and improvements in the labour market have been so anaemic that it is too early to call the end of the Eurozone recession. Indeed, if this is what an expansion looks like, then the state of the Eurozone economy might be even worse than economists feared.

Young firms are known to play a central role in job creation. This column presents the results of a new OECD project on the dynamics of employment (DynEmp) based on an innovative methodology using firm-level data. It confirms that young firms play a central role in creating jobs, and in enhancing growth and innovation. Public policies can help by enabling firms to experiment, and by fostering the reallocation of resources towards the most productive firms. Structural reforms to product, labour, and capital markets, as well as bankruptcy laws that do not overly penalise failure, are particularly relevant.

Before the introduction of the euro, it was hoped that by promoting increased intra-regional trade it would increase business-cycle synchronisation within the Eurozone, and thus help it to fulfil the criteria for an optimum currency area. This column presents recent research that compares the evolution of business-cycle synchronisation in the Eurozone and east Asia. While the euro has had some impact on business-cycle synchronisation in the Eurozone, it has done so not through increased intra-regional trade intensity, but rather through some other channel – most likely financial integration.
