Assuming a 0.1 percentage point permanent increase in long-term inflation expectations, three simulation modalities are contrasted according to the perception of shock by i) all agents ii) all agents (also including firms as in the first modality), but excluding the household sector or iii) the financial sector only. The ECB-BASE can be used to perform a sensitivity analysis on the macroeconomic implications of an illustrative exogenous shift in long-term inflation expectations. On the other hand, where financial market participants increase their long-term inflation expectations by more than other economic agents and this is reflected in market prices, the subsequent rise in nominal financing costs translates into higher real rates for households and firms which may weigh on their spending decisions.

The key mechanisms at play operate through the perceived real rates across economic agents: to the extent that households and firms update their long-term inflation expectations, higher long-term nominal yields could still be consistent with lower real rates and thereby provide an expansionary effect on spending. Heterogeneous perceptions across economic agents could indeed significantly affect the associated macro-financial implications. These features are well suited to examining the transmission of changes in long-term inflation expectations. In the context of central bank macroeconomic models, the large semi-structural model ECB-BASE can be operated under various expectations settings and allows for some heterogeneous design across model agents. ), rational inattention (Maćkowiak and Wiederholt ) and sticky information (Reis ). Accordingly, the literature has modified macroeconomic models to incorporate alternative mechanisms of expectations formation, such as learning (Slobodyan and Wouters ), hybrid expectations (Levine et al. At the same time, data cannot explain exactly how expectations are formed and there is evidence suggesting departures from rational expectations, even if some convergence towards rational expectations over time cannot be excluded. A significant part of the literature on structural macroeconomic models relies on the assumption of rational expectations and perfect common knowledge among economic agents. The macroeconomic implications of alternative mechanisms of expectations formation, their heterogeneity across economic agents and the interplay with monetary policy remain an active field of theoretical and empirical research.

For ILS, the short term is calculated as the percentage deviation between the two-year-ahead swap rate and the one-year-ahead swap rate and the long term corresponds to the percentage difference between the ten-year-ahead swap rate and the five-year-ahead swap rate. In the case of the SPF, the short term is the 2021 expected annual inflation and the long term is the five-year-ahead expected annual inflation. For each source of inflation, long-term and short-term expectations differences are shown. The second is the inflation calculated from the euro area inflation-linked swap (ILS) rates. It corresponds to the average of point forecasts given by the forecasters.

The first one is HICP inflation expectations from the ECB Survey of Professional Forecasters (SPF). Two sources of expected inflation are compared.

(changes between Q4 2020 and Q1 2021, year-on-year growth rates, percentage points) This issue is explored through the lens of the ECB-BASE model, conducting illustrative simulations where the agents modelled have different perceptions of a shift in long-term inflation expectations.Ĭhanges in HICP expectations in the SPF and ILS rates In assessing the macroeconomic implications of a rise in long-term inflation expectations, a critical factor with regard to the propagation mechanism is whether other sectors of the economy (notably households and firms) share the same expectations as priced by financial markets. As shown in Chart A, between the fourth quarter of 2020 and the first quarter of 2021, inflation expectations increased only slightly according to the ECB Survey of Professional Forecasters (SPF), while this pattern was more pronounced for market-based measures. Over the recent period, long-term inflation expectations of financial market participants, which can be measured either from financial market instruments like inflation-linked swaps (ILS) or from surveys of professional forecasters, have been rising. This box explores how heterogeneous expectations across agents can change the macroeconomic outcomes of an increase in long-term inflation expectations.
