There are several classes of boom-and-bust economic cycles. It has been difficult to predict these cyclic catastrophes systematically, because they are related to biological phenomena. Recently, we proposed a model for explaining the reason why organs such as a blast cyst, ectodermal endoderm, mesoderm, heart, and hand generate at about sevenfold cell divisions during the morphogenic process. In this report, we will show that the morphogenetic process with a rhythm of about seven beats is similar to several economic system cycles, because several types of economic cycles are about seven times the length of the fundamental production cycles or durable periods. The shortest economic cycle is also 1week of 7 days. The longest type of economic catastrophe repeats with an interval of about 70 years, while the actual durable period of the longest lasting products is about 10 years.
