This paper evaluates the empirical validity of the New Keynesian Phillips Curve (NKPC) model of rational expectations. We employ an instrumental variable (IV) projection method to approximate inflation expectations, and show that the inference based on this approach can differ significantly from...

The ability of the New Keynesian Phillips curve to explain US inflation dynamics when official central bank forecasts (Greenbook forecasts) are used as a proxy for inflation expectations is examined. The New Keynesian Phillips curve is estimated on quarterly data spanning the period...

Some observers have worried that under or over-estimating the output gap may unnecessarily induce tightening or loosening of monetary conditions, causing real fluctuations. To investigate the relationship between the output gap and inflation, we examine models of inflation that do and do not use...

As both the natural level of output and the New Keynesian output gap cannot be observed in practice, there is quite some debate on the question how these variables look like in practice. Rather than taking the standard approach of using a time trend or the HP-filter to obtain estimates of these...

The Phillips curve has been at the same time an econometric object, a trade-off curve and an analytical equation representing the aggregate supply in a macro model. The paper considers these aspects as they emerge from the so called new “neoclassical synthesis'' models used for monetary...

In this paper we propose a straightforward method to derive a non-accelerating inflation capacity utilisation rate (NAICU) based on micro data. We condition the current capacity utilisation of firms on their current and planned price adjustments. The non-accelerating inflation capacity...

In this paper we propose a straightforward method to derive a non-accelerating inflation capacity utilisation rate (NAICU) based on micro data. We condition the current capacity utilisation of firms on their current and planned price adjustments. The non-accelerating inflation capacity...

This paper analyses the interplay of capacity utilisation, capacity constraints, demand constraints and price adjustments, employing a unique firm-level data set for Swiss manufacturing firms. Theoretically, capacity constraints limit the ability of firms to expand production in the short run...

In a small-scale New-Keynesian model with a hybrid Phillips curve and IS equation, the paper is concerned with an arbitrary frequency of the agents’ synchronized decision making. It investigates the validity of a fundamental methodological precept according to which no substantive prediction...

This paper shows how endogeneous inflation inertia is generated by a simple modificaton of the quadratic adjustment cost structure faced by economic agents. We derive the pertinent inflation relationships based on purely nominal rigidities and show that they always involve additional expectation...
