What is the history of the concept of credibility?

[C]redibility was initially coined as an explanandum for the success and failure of Western monetary, anti-inflationary policies in the 1970s (Kydland and Prescott, 1977; Fellner, 1979). The widely flaunted idea was that the success of economic policy ultimately depends on the (state’s) credible commitment to free markets, trade liberalization, the privatization of government-owned enterprises and resources, and legal security for property rights. In this sense, the initial reading of the notion of credibility has a distinct neo-liberal signature. See Peter Ho, “The ‘Credibility Thesis’ and its Application to Property Rights: (In)secure Land Tenure and Social Welfare in China”, Land Use Policy, 2014, Vol. 40, September, pp. 15–16.
