Borrowed capacity builds upon institutional capacity scholarship to discuss how interactions between government agencies and interest groups can increase agency resources and scope during agency formation and development. Equal Employment Opportunity Commission scholars often note the lack of capacity to implement Title VII of the Civil Rights Act of 1964 during the first years of the agency. I argue that current assessments of the agency’s capacity between 1965 and 1968 are incomplete by expanding the definition of capacity to include borrowed and nontraditional forms of capacity, reviewing congressional allocations to the agency and agency budgets, and considering the active roles state and local agencies as well as interest groups played in the early implementation of Title VII. I demonstrate the agency amassed not only claims but also capacity during its early years.
