This paper generates new evidence for England and Wales on the importance of labour pooling as a source of agglomeration economies. Estimates of worker and firm productivity are obtained from longitudinal worker and firm micro-data and used to test the hypothesis that denser labour markets increase the quality of the matching between employees and employers across labour markets. Our findings provide evidence supportive of a positive relationship between the quality of the employee-employer matching and the economic size of labour markets.


Este trabajo aporta a Inglaterra y Gales nuevas pruebas sobre la importancia de la puesta en común de la mano de obra, como fuente de economías de aglomeración. Las estimaciones de la productividad del trabajador y la empresa se obtienen de micro-datos longitudinales sobre trabajadores y empresas y se utilizaron para poner a prueba la hipótesis de que los mercados laborales más densos aumentan la calidad del emparejamiento entre empleados y empleadores en los mercados de trabajo. Nuestros resultados aportan pruebas que apoyan una relación positiva entre la calidad del emparejamiento empleado-empleador y el tamaño económico de los mercados laborales.
