The New Keynesian model with rational expectations unrealistically predicts that unanticipated credible changes in the inflation target lead to an immediate jump in the inflation level while the output gap is unaffected. We set up a theoretical model where agents learn the behaviour of the...

Central banks, whether independent or not, may occasionally be subject to external pressures to change policy objectives. We analyze the optimal response of central banks to such pressures and the resulting macroeconomic consequences. We consider several alternative scenarios regarding policy...

The modelling of expectations and its degree of backward looking behaviour are issues of main concern in the inflation dynamics research agenda. One approach in the literature is to use expectations from surveys as an approximation to actual expectations. We estimate the Phillips curve allowing...

This paper shows that a simple form of nonlinearity in the Phillips curve can explain why, following the Great Recession, inflation did not decrease as much as predicted by linear Phillips curves, a phenomenon known as the missing disinflation. We estimate a piecewise-linear specification and...
