In this article, two of the organisers highlight some of the main points from the papers and discussions, including why measured economic slack did not translate into more vivid price and wage growth, which role inflation expectations play in the conduct of monetary policy as well as where the challenges lie in reconciling changes in firms’ micro price-setting with aggregate inflation dynamics. This year’s ECB Forum on Central Banking focused on the core issue for monetary policy of why inflation accelerated so moderately in the recoveries that followed the crises in advanced economies. Policymakers, academics and market economists debated price and wage-setting from both macroeconomic and microeconomic perspectives. In this introductory chapter we summarise four of the main themes that were keenly debated in Sintra in June 2018: explanations as to why the Phillips curve has flattened and its implications; the sources and implications of low real wage growth; central bank communication with respect to inflation expectations; and key challenges in reconciling changes in micro price-setting behaviour with macroeconomic inflation developments. The full set of papers, discussions and speeches can be found in the other chapters of these proceedings and video recordings of all sessions on the Sintra Forum website.2 1 Slack and the flat Phillips curve: international factors, regime switches, slow adjustment or mismeasurement? The vanishing slope of the Phillips curve over the last few decades raises major questions about how the low-inflation phenomenon should be understood (see the previous discussion on this at the 2015 Sintra Forum; Constâncio et al. 2015). Put 1 Both European Central Bank. We are grateful to Benoît Cœuré, Luca Dedola, Martin Eiglsperger and Peter Praet for comments and discussions. All views expressed are summarised to the best of the authors’ understanding from the various Sintra participants’ Forum contributions and should not be interpreted as the views of the ECB or the Eurosystem.

ECB Forum on Central Banking, June 2018 6 another way, the empirical relationship between economic slack and wage and price developments seems to have weakened considerably in many advanced economies. Participants put forward many arguments that could explain why the Phillips curve is flat. In the opening paper, Jim Stock and Mark Watson (2018) argue that mismeasurement of inflation may be one culprit. Once price index components that do not react to the business cycle (or that are badly measured) as well as trends are taken out, the negative relationship between different measures of slack and the resulting indicator of “cyclically sensitive inflation” (CSI) in the United States remains stable and statistically significant over the last few decades. Chart 1 shows that the CSI indicator estimated by Stock and Watson for the euro area (black solid line) increased only very gradually in the last few years (see ECB 2014 for a similar methodology). This would suggest that the observed low inflation in the euro area is not a measurement artefact. In contrast to the US CSI, it is also quite close to the Harmonised Index of Consumer Prices (HICP) excluding energy and food (dashed blue line), a more standard measure of “core inflation” (which takes the most volatile components out of the index).
