The New Keynesian Phillips Curve (NKPC) is now the dominant model of inflation dynamics. In recent years, a large body of empirical research has documented price-setting behaviour at the individual level, allowing the assessment of the micro-foundations of pricing models. This paper analyses the...

The Phillips curve has flattened in Spain over 1995-2006: unemployment has fallen by 15 percentage points, with roughly constant inflation. This change has been more pronounced than elsewhere. We argue that this stems from the immigration boom in Spain over this period. We show that the New...

This document contains the text of the 1998 Central Banking Lecture delivered at the London School of Economics and Political Science on June 4th. It starts by asking what factors have been behind the remarkable retreat of inflation that has taken place internationally since the mid-eighties,...

This paper analyzes the effects of monetary shocks in a DSGE model that allows for a general form of smoothly state-dependent pricing by firms. As in Dotsey, King, and Wolman (1999) and Caballero and Engel (2007), our setup is based on one fundamental property: firms are more likely to adjust...

During the 1970s and early 1980s, Spain suffered high rates of inflation but inflation declined and by 1997 inflation had fallen to approximately 2 percent. To fight inflation, Spain implemented austere monetary programs, joined the EMS in 1989, enacted central bank autonomy in 1994, and...

An exogenous oil price shock raises inflation and contracts output, similar to a negative productivity shock. In the standard New Keynesian model, however, this does not generate a tradeoff between inflation and output gap volatility: under a strict inflation targeting policy, the output decline...

The purpose of the present paper is twofold. First, we characterize de Fed's systematic response to technology shocks and its implications for US output, hours and inflation. Second we evaluate the extent to which that responses can be accounted for by a simple monetary policy rule in the...

Recent treatments of the issue of a zero floor on nominal interest rates have been subject to some important methodological limitations. These include the assumption of perfect foresight or the introduction of the zero lower bound as an initial condition or a constraint on the variance of the...

Emerging economies with inflation targets (IT) face a dilemma between fulfilling the theoretical conditions of "strict IT", which imply a fully flexible exchange rate, or applying a "flexible IT", which entails a de facto managed floating exchange rate with FX interventions to moderate exchange...

This paper presents a model featuring variable utilization rates across firms due to production inflexibilities and idiosyncratic demand uncertainty. Within a New Keynesian framework, we show how the corresponding bottlenecks and stock-outs generate asymmetries in the transmission mechanism of...
