This entry explicates neoliberalism by examining the political concepts, principles, and policies shared by F. A. Hayek, Milton Friedman, and James Buchanan, all of whom play leading roles in the new historical research on neoliberalism, and all of whom wrote in political philosophy as well as political economy. Identifying common themes in their work provides an illuminating picture of neoliberalism as a coherent political doctrine.

But several recent book-length treatments of neoliberalism (Burgin 2012; Biebricher 2018; Slobodian 2018; Whyte 2019) have helped give form to an arguably inchoate political concept. As Quinn Slobodian argues,

in the last decade, extraordinary efforts have been made to historicize neoliberalism and its prescriptions for global governance, and to transform the “political swearword” or “anti-liberal slogan” into a subject of rigorous archival research. (2018: 3)

Along similar lines, Thomas Biebricher (2018: 8–9) argues that neoliberalism no longer faces greater analytic hurdles than other political positions like conservatism or socialism.

In light of this recent historical work, we are now in a position to understand neoliberalism as a distinctive political theory. Neoliberalism holds that a society’s political and economic institutions should be robustly liberal and capitalist, but supplemented by a constitutionally limited democracy and a modest welfare state. Neoliberals endorse liberal rights and the free-market economy to protect freedom and promote economic prosperity. Neoliberals are broadly democratic, but stress the limitations of democracy as much as its necessity. And while neoliberals typically think government should provide social insurance and public goods, they are skeptical of the regulatory state, extensive government spending, and government-led countercyclical policy. Thus, neoliberalism is no mere economic doctrine.

The actual work of Milton Friedman and co. should work best for that, they don’t hide it! ;)
