We examine mobility in two dimensions: from firm to firm (inter-firm) and from one technical field to another. We exploit data on patents filed by inventors from five countries (France, UK, Germany, US and Japan) in the USPTO during the period from 1975 to 2002. From our regressions, we show that: (1) as predicted by evolutionary theory, inventor productivity is a positive determinant of invention value, (2) inter-firm mobility is a consistently positive determinant of productivity and (3) technological mobility is a negative determinant.]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[Resumen: El objetivo de este artículo es proporcionar un nuevo entendimiento de 1) las determinantes del valor de las invenciones y 2) el papel que juega la movilidad en los inventores prolíficos, identificados como tales con base en el número de patentes que exceden el umbral de productividad. La movilidad es examinada en dos dimensiones: de firma a firma (interfirma) y entre campos técnicos. Se utilizan datos de patentes registradas por inventores de cinco países (Francia, Reino Unido, Alemania, Estados Unidos y Japón) en la USPTO durante el periodo de 1975 a 2002. Los resultados de las regresiones muestran que 1) tal como predice la teoría evolutiva, la productividad de los inventores es una determinante positiva del valor de la invención, 2) la movilidad interfirmas es una determinante consistentemente positiva en la productividad y 3) la movilidad tecnológica es una determinante negativa.]]></p></abstract>
