This study examined the effect of human and social capital upon firm d
issolution with data ham a population of Dutch accounting firms for th
e period 1880-1990. Human capital was captured by firm-level proxies f
or firm tenure, industry experience, and graduate education. The socia
l capital proxy was professionals' ties to potential clients.. Human a
nd social capital strongly predicted firm dissolution, and effects dep
ended an their specificity (uniqueness) and nonappropriability (the ow
nership status of that capital). Findings suggest an integration of th
e resource-based view of the firm and organizational ecology and a con
comitant stimulant for future research along these lines.
