Official price indexes, such as the CPI, are imperfect indicators of inflation calculated using ad hoc price formulae different from the theoretically well-founded inflation indexes favored by economists. This paper provides the first estimate of how accurately the CPI informs us about "true"...

The great contraction of 2008 pushed the U.S. economy into a protracted liquidity trap (i.e., a long period with zero nominal interest rates and inflationary expectations below target). In addition, the recovery was jobless (i.e., output growth recovered but unemployment lingered). This paper...

Firms employ a rich variety of pricing strategies whose implications for aggregate price dynamics often diverge. This situation poses a challenge for macroeconomists interested in bridging micro and macro price stickiness. In responding to this challenge, we note that differences in macro price...

Empirical data show that firms tend to improve their ranking in the productivity distribution over time. A sticky-price model with firm-level productivity growth fits this data and predicts that the optimal long-run inflation rate is positive and between 1.5% and 2% per year. In contrast, the...

In this paper we incorporate the two most prominent approaches of inequality aversion, i.e. Fehr and Schmidt (1999) and Bolton and Ockenfels (2000) into an otherwise standard New Keynesian macro model and compare them with respect to their influence on the long-run effectiveness of monetary...

This paper shows that announced credible disinflations under inflation targeting lead to a boom in a standard New Keynesian model (i.e. a disinflationary boom). This finding is robust with respect to various parameterizations and disinflationary experiments. Thus, it differs from previous...

We present a new partial equilibrium theory of price adjustment, based on consumer loss aversion. In line with prospect theory, the consumers' perceived utility losses from price increases are weighted more heavily than the perceived utility gains from price decreases of equal magnitude. Price...

In this paper we empirically investigate the time- and state-dependent behavior of aggregate price setting. We implement a testing procedure by means of a nonparametric representation of the structural form New Keynesian Phillips curve. By means of the so-called functional coefficient regression...

The paper studies the effects of credible disinflation in the presence of real wage rigidity, comparing the Calvo and Rotemberg price setting mechanisms (the two popular variants of the New-Keynesian model). In both types of models, a credible, gradual disinflation is shown to lead to a delayed...

Deflation is said to dampen aggregate demand because consumers would defer purchases while waiting for prices to fall further in the future. We explore the validity of this reasoning at the level of individual goods. Our findings suggest that the widespread concerns about impaired aggregate...
