Public expenditure averaged 42 percent of GDP between 1967 and 2010. In general, it varied with the business cycle, rising in recessions and declining in the economic upswings, as the tax yield increased and welfare payments declined relative to GDP...public expenditure was still running at 42 percent of GDP when New Labour returned to power in 1997.
For the first few years, New Labour stuck rigidly to the previous Conservative government’s spending plans, bringing public expenditure relative to GDP to 37 percent in 2000-01, its lowest point for 50 years and far lower than under Thatcher. Gordon Brown, the chancellor of the exchequer, only allowed expenditure to rise in absolute terms after 1999 and surpass the Conservatives’ spend, relative to GDP, in 2005.
This increase was, however, quite different from the rest of the post-war period because it rose quite sharply in a period of economic growth...Who benefited from the increased spending is revealing... The number of public sector workers rose from 4.8 million in 1997 to 5.4 million in 2008. This 12 percent increase was far less than the 42 percent increase in public expenditure. And the number employed, at 20 percent of the total workforce in 2008, was still less than in the early 1990s.
So the 42 percent increase in public expenditure was not eaten up by the workforce.So where did the money go? It went to private business. In the name of efficiency, the Labour government continued and extended the Conservatives’ policy of outsourcing public services, including almost all local government functions. A report commissioned by the Department for Business Enterprise and Regulatory Reform found that by 2007-08, of the £300 billion spent on services (as opposed to welfare payments, interest and investment), £159 billion was spent on pay and £141 billion on procurement. Just 53 percent was spent in-house. Of the £141 billion spent on procurement, £79 billion went to the new and burgeoning “public services industry”...
