• Purpose: To explore the relationship between knowledge based capabilities with prior make or buy decisions and buyer-supplier differences in the management of skilled employees.
• Knowledge Work: Consists of activities, tasks, or projects that require the application of knowledge to solve business problems.
• Firm-specific Human Capital (HC): Knowledge and skills that are unique to a firm.
• Industry Specific HC: Knowledge about the industry setting or domain in which a project is situated, and thus it is re-deployable across the (limited) set of firms with projects in the same industry domain.
• Occupational HC: Knowledge and skills required to perform work within a professional or functional area.

• 1989 Survey of Fortune 500 Firms
– Sample includes all 129 Publicly listed Firms
– All firms are in technology-based industries
– 5 industries included:
• Chemicals (39 firms)
• Computer Manufacturing (22 firms)
• Electronics (40 firms)
• Pharmaceuticals (12 firms)
• Scientific and Photographic Equipment (16 firms)
– Patents from 1990-1995
– Sample size included 59,590 patents

• H1: Firms are less likely to outsource knowledge projects the greater their relevant firm-specific human capital developed by performing prior related projects.
• Theory: Governance Inseparabilites (Argyres and Liebeskind,1999);
Time Compression Diseconomies (Dierickx and Cool, 1989); among others.
• Operationalization: Firm-specific HC was measured as the number of backward citations to patents of the same company that were also processed in-house during the previous five years.
• Findings: H1 Supported.
6
• H2: Firms are less likely to outsource knowledge projects the greater the relevant industry-specific human capital developed by previously internalizing knowledge projects in the same domain.
• Theory: Mixture of KBV and TCE logic (e.g., Argote & Ingram,
2000; Hatch & Dyer, 2004; Parmigiani & Mitchell, 2009).
• Operationalization: Industry-specific HC was measured as the company’s previous in-house experience in the technical domain.
Specifically, it was the logged number of prior patents processed internally by the firm in the same primary seven-digit International
Patent Classification.
• Findings: H2 Supported.
7
• H3: The marginal impact of higher firm-specific or industryspecific human capital on the tendency of firms to internalize knowledge work is highest when the other type of human capital (firm specific or industry specific is low ).
• Theory: KBV. Focus on advantages of coordinating knowledge tasks (e.g., Kogut & Zander, 1992; Conner &
Prahalad, 1996; Nickerson & Zenger, 2004).
• Operationalization: Interaction Term
• Findings: H3 Supported.
8
• H4: Firms are more likely to outsource knowledge projects situated in areas that are highly contested (and thus rely heavily on occupational human capital).
• Theory: Focuses on TCE logic (e.g., Williamson’s 1985 concept of selective intervention) to explain why firms develop in-house occupational human capital but the authors main question is not on why but when occupational human capital is outsourced.
• Operationalization: Dummy variable coded as 1 if the focal patent cited a patent that was litigated in the past (referred to as a high contested area).
• Findings: H4 Supported.
9
• H5: The larger the firm’s internal staff (in the focal occupational area), the weaker the (positive) effect of a project being in a highly contested area on the probability of outsourcing.
• Theory: KBV. The logic is that firms with more patent attorneys may use knowledge hierarchies to leverage skills and learning
(e.g., Garicano, 2000).
• Operationalization: Interaction of highly contested area (see H4) with internal staff size, which measures the number of patent attorneys employed by the focal firm.
• Findings: H5 Supported.

• Theoretical Contribution?
- Provides strong links between KBV and TCE.
• Sample Issues?
- Limited to big Fortune 500 firms.
• Measurement Issues?
-Research design included interviews with managers to verify important measurement issues. Measurements are consistent with patent literature.
• Model Specification/Identification Issues?
- Model does not include variables on firm capabilities other than patenting experience. Is the main-case causality that greater outsourcing leads to lower firm capabilities, or that lower firm capabilities lead to outsourcing?
