¿Quién se empareja con quién en el mercado laboral español? Un análisis cluster basado en la Muestra Continua de Vidas Laborales

Abstract

Our study addresses empirical tools that are useful to capture the role of heterogeneities in the labor matching process. We develop an application of our methodology to the Spanish labor market based on the data from the Muestra Continua de Vidas Laborales (Continuous Sample of Working Lives). These data contain information about the worker and the job that form each job placement, which allows us to group in worker and job segments on the basis of their characteristics. These segments can be also grouped respectively in worker and job clusters, which finally can be combined among them attending to their matching. Those joint clusters (or biclusters) with the highest propensity to match can be considered specific “job creation” markets, whose structure can be studied in detail —for example, analyzing the employment duration—. Our empirical methodology, which can be very versatile in its application (of which we provide several examples), allows showing the important labor market segmentation, and it can be useful for the efficient design of active employment policies, for instance of labor mobility.
