Back-sourcing is the practice of bringing a once outsourced process back to the originating firm. Prior research have established that the opposite of back-sourcing, outsourcing, has generated positive market reactions. This study uses event study methodology to examine market reactions to back-sourcing. The results strongly support the idea that back-sourcing is a good strategic decision.
