Essentially, the paper dives into the conditions that can convert an economy from equilibrium-seeking to self-perpetuation:
Minsky identifies hedge, speculative, and Ponzi finance as distinct income-debt relations for economic units. He asserts that if hedge financing dominates, then the economy may well be an equilibrium-seeking and containing system: conversely, the greater the weight of speculative and Ponzi finance, the greater the likelihood that the economy is a “deviation-amplifying” system. Thus, the FIH suggests that over periods of prolonged prosperity, capitalist economies tend to move from a financial structure dominated by hedge finance (stable) to a structure that increasingly emphasizes speculative and Ponzi finance (unstable).
