We investigate the relevance of Carroll's sticky information model of inflation expectations for four major European economies (France, Germany, Italy and the United Kingdom). In contrast to the most rational expectation models, households in the sticky information environment update their...

This paper surveys the current state of global empirical research on price setting behaviour at the firm level to evaluate the adequacy of pricing models used in the macro literature. To that end, it analyses the implications of 25 theoretical models (sticky information, menu costs, time...

We estimate impulse responses of sectoral price indexes to aggregate shocks and to sector-specific shocks. In the median sector, 100 percent of the long-run response of the sectoral price index to a sector-specific shock occurs in the month of the shock. The standard Calvo model and the standard...

I present and solve the problem of a producer who faces costs of acquiring, absorbing, and processing information. I establish a series of theoretical results describing the producer's behaviour. First, I find the conditions under which she prefers to set a plan for the price she charges, or...

This paper considers whether the Phillips curve can explain the recent behavior of inflation in the United States. Standard formulations of the model predict that the ongoing large shortfall in economic activity relative to full employment should have led to deflation over the past several...

Empirical research has shown that there is large uncertainty concerning the value of the natural rate of unemployment at any point in time. I incorporate this feature in a model of monetary policy where the policymaker targets an inflation rate and the natural rate of unemployment and solve for...

This chapter examines the concept of inflation persistence in macroeconomic theory. It begins by defining persistence — emphasizing the difference between reduced-form and structural persistence. It then examines a number of empirical measures of reduced-form persistence, considering the...

The New Keynesian Phillips Curve is at the centre of two raging empirical debates. First, how can purely forward looking pricing account for the observed persistence in aggregate inflation. Second, price-setting responds to movements in marginal costs, which should therefore be the driving force...

Should central banks increase their degree of transparency any further? We show that there is likely to be an optimal intermediate degree of central bank transparency. Up to this optimum more transparency is desirable: it improves the quality of private sector inflation forecasts. But beyond the...

This paper introduces deep habits into a sticky-price sticky-wage economy and asks whether the countercyclical markup movements induced by deep habits is helpful for accounting for the dynamic effects of monetary policy shocks. We find that this is the case: When allowing for deep habits, the...
