Furthermore, Nordhaus rewrote significant sections to reflect contemporary thinking in finance and monetary policy. Key updates included a revised view of financial markets (Ch. 23) and a shift away from a purely quantitative view of the money supply towards an "interest-rate world" in the discussion of monetary policy (Ch. 24).
