A Model of R&D Capitalization

This paper studies the decision of firms to expense or capitalize R&D expenditures. The firm has an incentive to mismatch the benefits and costs of R&D, expensing a larger portion of R&D when the benefits occur in the long-run and capitalizing a larger portion when the benefits occur in the short-run. There is strategic substitutability between R&D investments and expensing. Accounting standards, market evaluation of capitalization, and firms¡¦ accounting policies can have real effects on innovation.
