 All three thinkers take great pains to answer Keynesian arguments for government intervention. Hayek’s (1941 [2007]) arguments concern how government spending and the monetary authority’s actions affect the structure of capital goods across the economy. Contra Keynes’s (1935 [1965: 37–45]) comfort with statistical aggregates in the General Theory, Hayek (1941 [2007]) contends that relying on simple economic aggregates obscures how capital and investment are structured across the economy. Hayek also thinks the premier cause of recessions is policy that makes bank credit too easy, which leads to malinvestment that has to be liquidated in a bust. Importantly Hayek’s critique of Keynes was not influential in the latter half of the twentieth century. Friedman’s and Buchanan’s ideas, especially Friedman’s, carried more weight.
