Tie strength in job change :

Evidence from business card exchange in Japan

Abstract

Japan has a unique culture where people exchange business cards in nearly every formal and informal setting. Capturing data from the business card exchange process allows us to reconstruct the structure and dynamics of job change in a large social network (over 1.5M individuals for 3 years). Contrary to Granovetter’s strength of weak tie hypothesis, we find there is a positive relationship between network constraint and job change, which suggests that strong cohesive ties contribute more to employment mobility than do bridging weak ties.
