This study takes a closer look into the equivalence result of Baliga (1999) namely, that a principal obtains the same optimal collusion-proof payoff for both hard and soft information. In the procurement model of Baliga (1999), we consider the sensitivity of equivalence to monitoring technologies, the agent's type-dependent reservation utility, and the supervisor's career concerns. We also show that career concerns may exacerbate the collusion problem. In response, the principal refrains from fully revealing the supervisor's performance to the future employer, hence generating informational frictions in the labor market. |
