Making a success of welfare reform has as much to do with implementation as with policy design. The experience in Wisconsin and New York generalises too much of the US, with states divided into those successfully implementing work-based reform, those incapacitated by partisan divisions and those that have never seriously framed welfare policy. Three decisions are key: the degree of toughness, the amount of programme integration; and the locus of administrative control which are shaped by long standing differences in political culture, moralistic, individualistic and traditionalistic. States adopting a moralistic approach to policy administration generally achieve most success.
