The non-accelerating inflation rate of unemployment (NAIRU) describes the rate of unemployment at which there is equilibrium between workers’ wage growth aspirations and the objective of firms of maximizing profits. In this article, we develop a theoretical model with the aim of quantifying the NAIRU. This aspect is particularly relevant, both from a theoretical and empirical approach, as equilibrium unemployment rate has increased in most European countries. However, as this rate is not directly observable, we suggest the use of econometric methods that involves the use of the Kalman filter. To illustrate the potentiality of this approach and the role of certain variables related to wage rents distribution, we have analyzed the evolution of the NAIRU in Spain for the period 1964-2004. La tasa de paro de inflación estable (NAIRU) describe aquella tasa de desempleo que se alcanza en el equilibrio entre las reivindicaciones salariales de los trabajadores y los objetivos de beneficio de las empresas. En este trabajo se desarrolla un enfoque teórico general que permite determinar el nivel de la NAIRU. Esta cuestión adquiere una especial trascendencia teórica y empírica si se tiene en cuenta que esta tasa de paro de equilibrio ha aumentado en la mayoría de países europeos. Sin embargo, esta tasa de paro de equilibrio no puede observarse directamente por lo que se recurre a su estimación econométrica a partir del filtro de Kalman. Para ilustrar la potencialidad del modelo desarrollado y la influencia de la determinadas variables relacionadas con la distribución de las rentas salariales, se analiza cual ha sido la evolución de la NAIRU para la economía española en el periodo 1964–2004.
