Editing Henry George (section)

===Henry George theorem===
{{main|Henry George theorem}}
In 1977, [[Joseph Stiglitz]] showed that under certain conditions, spending by the government on [[Public good (economics)|public good]]s will increase aggregate land rents by at least an equal amount. This result has been dubbed by economists the [[Henry George theorem]], as it characterizes a situation where Henry George's "single tax" is not only efficient, but also the only tax necessary to finance public expenditures.<ref>{{cite journal |last=Arnott |first=Richard J. |author2=Joseph E.
