“Weak ties”, a valuable aid in getting a job, are generally work ties. One reason for this feature is not that former colleagues increase one’s information but rather that they value the pursuit of past collaboration. We examine the consequence of the collaboration ties hypothesis in the financial industry labor market. In finance, the labor market values the assets that financial operatives take with them from one firm to another, such as knowledge, know-how and customers. Since assets are to a certain extent shared among co-workers, it is worth hiring business relations and former colleagues or moving in teams: this enables a better transfer of assets such as idiosyncratic work routines, distributed knowledge, or joint customers. To demonstrate our claims we rely on an online survey launched with eFinancialCareers.fr collected in September 2008 among French financial employees. This questionnaire shows that working at the core of financial markets favors the accumulation of key moveable assets on the one hand and of collaboration ties on the other. That is, collaboration ties and key moveable assets are strongly correlated. The moving of key assets, collaboration ties and notably the combination of those two dimensions all result in increased wages.
