Abstract
Big technological improvements in a new, secondary sector lead to a period of excitement about the future prospects of the overall economy, generating boom-bust dynamics propagating through credit markets. Increased future capital prices relax collateral constraints today, leading to a boom before the realisation of the shock. But reallocation of capital toward the secondary sector when the shock hits leads to a bust going forward. These cycles are perfectly foreseen in our model, making them markedly different from the typical narrative about unexpected financial shocks used to explain crises. Our dynamics obtain without a departure from rational expectations. In fact, these cycles echo Minsky's original narrative for financial cycles, according to which 'financial trauma occur [sic] as normal functioning events in a capitalistic economy' (Minsky, 1980, p. 21).

We explore empirically models of aggregate fluctuations in which consumers form anticipations about the future based on noisy sources of information and these anticipations affect output in the short run. Our objective is to separate fluctuations due to changes in fundamentals (news) from those due to temporary errors in agents' estimates (noise). We show that structural VARs cannot be used to identify news and noise shocks, but identification is possible via a method of moments or maximum likelihood. Next, we estimate our model on US data. Our results suggest that noise shocks explain a sizable fraction of short-run consumption fluctuations. (JEL D84, E13, E21, E32)

The relationship between the Phillips curve and inflation has become weaker over time, producing questions regarding how policymakers might connect inflation to the rest of the economy. Presentations given during the "Inflation: Drivers and Dynamics" session of the Central Bank Research Association's annual meeting focused on the intersection of monetary policy and inflation dynamics to examine the ways in which policy might impact inflation and related expectations and processes. This Economic Commentary summarizes the papers presented during this session.
