Advertising agency operating efficiency

This study uses data envelopment analysis to evaluate the operating efficiency of a sample of 41 US advertising agencies, based on their profits and expenditures in six key areas (i.e., payroll to employees, other payroll-related expenses, administrative expenses, space and facilities expenses, corporate expenses, and professional fees). The analyses reveal that, on average, 5% of an agency's budget is wasted, incurring the greatest amount of waste in the administrative and corporate expenses. The tobit model also indicates that professional fees contributed the most agency inefficiency overall.
