A translog function is specified to represent the relation between revenue and human resource inputs in public accounting firms. Estimation of the model using a balanced panel of annual data for 64 large CPA firms for the period 1995–1999 indicates that increasing returns to scale prevail in the public accounting industry, justifying recent merger and acquisition activities among accounting firms. Average marginal revenue product of partners increased monotonically from 1995 to 1998, decreased slightly in 1999, and was about nine times that of other professionals during 1995–1999. The public accounting industry exhibited continuing improvement in productivity over the 5 years.

The paper examines the determinants and performance consequences of equity grants to senior-level executives, lower-level managers, and non-exempt employees of “new economy” firms. We find that the determinants of equity grants are significantly different in new versus old economy firms. We also find that employee retention objectives, which new economy firms rank as the most important goal of their equity grant programs, have a significant impact on new hire grants, but not subsequent grants. Our exploratory performance tests indicate that lower than expected grants and/or existing holdings of options are associated with poorer performance in subsequent years.
