Abstract

Welchen kausalen Effekt erfahren Freiberufler durch eine freiwillige Berufsverbandsmitgliedschaft auf ihr Erwerbseinkommen? Diese Frage soll durch die Schätzung von Fixed-Effects-Modellen für Männer und Frauen im Rahmen einer mikroökonometrischen Evaluation mit Daten des Sozio-oekonomischen Panels (SOEP) von 1985 bis 2009 beantwortet werden. Es werden positive kausale Effekte einer freiwilligen Mitgliedschaft auf das Einkommen von Freiberuflern sichtbar: für Männer betragen sie kurzfristig 1,84 %, mittelfristig 2,72 % und langfristig 4,12 %, für Frauen betragen die Effekte mittelfristig 5,18 %. Das soziale Kapital, das durch die Mitgliedschaft in Berufsverbänden gebildet wird, bewirkt also eine Einkommenssteigerung.
