Changing Costs of Public Services Mike G Phelps UKCeMGA ONS November 2009

Changing costs of public services • Public sector output and measures • Relative costs of public services • How costs are related to productivity and input prices • Relative costs of healthcare • Relative costs of education Note: Estimates are experimental

Output measures ONS measure approximately 65 per cent of government output directly As a result we can measure: • Productivity: output divided by input • The change in the cost of a unit of output: a measure of inflation for public service output

Cost of unit of public service output Changes in the unit cost of public service output give a measure of public service cost inflation However, most interest lies in how public service cost inflation compares with some overall measure of cost inflation This is the relative cost of a unit of public service output

Relationship between relative cost and productivity Productivity and Relative Cost are related measures Relative price of inputs = Relative cost of output Productivi ty

What are the drivers of rising relative unit costs? • The rise in input requirements has driven up relative unit costs of public service output • But the fact that aggregate public service input prices rose faster than whole economy costs made a bigger contribution

Conclusions Between 1997 and 2007: • cost of a unit of public service output grew by 13.7 more than cost inflation across the whole economy (annual average relative rise of 1.3 per cent) • the aggregate price of inputs grew by 9.8 per cent more than cost inflation across the whole economy • public service productivity fell 3.4 per cent However, in 2007, the relative cost of public service output fell for the first time since 1997 as productivity improved and relative input cost growth fell
