DP2558 Idiosyncratic Investments, Outside Opportunities and the Boundaries of the Firm
This paper adopts the incomplete contracting perspective to study a firm?s continuous choice between producing an essential input in-house (full integration), contracting part of the production out (tapered integration), and contracting all of the production out (non-integration), when (i) an idiosyncratic capacity investment is required to produce the essential input and (ii) under non-integration, outside opportunities are better. We show that the firm?s boundary choice depends crucially on its commitment power. If the firm can pre-commit to a particular provision mode, tapered integration will be chosen more frequently. Also, with commitment power the firm will never subcontract only a small portion of its input needs.
In-house capacity is in general smaller and outside capacity larger if the firm can pre-commit. Total capacity is never larger in the commitment than the non-commitment case.
