In the United States, for example, President Obama introduced an $800bon package of expanded unemployment benefits, increased welfare provision, tax incentives and various health, education and infrastructure projects.
Keynesian orthodoxy dominated the economic agenda and it was assumed that these stimulus policies would kick-start the recovery by replacing lower private spending with higher public spending and marshalling idle resources.
