It identifies a sequence of negative shocks to expectations for the 1927–32 period. The artificial economy predicts the 1928–32 depression and a long boom from 1933 onwards. Overall, a tangible fraction of interwar output volatility is attributed to sunspots.enJournal article002006037110.1093/oep/gpi0460002366139000052-s2.0-3364587418753026
