Neoliberalism emerged in the late 20th century as a response to Keynesian economics and the stagflation of the 1970s. It advocated for reducing state involvement in markets and increasing privatization, deregulation, and trade liberalization. While it led to some economic growth, it also increased inequality and failed to significantly reduce poverty or strengthen state capacity in many places. The 2008 financial crisis undermined confidence in neoliberal policies, though market-oriented reforms still influence development approaches today.
