Egg Cycle

Japanese: エッグ・サイクル - えっぐさいくる

...This is because when small producers expand production in response to high prices during production planning, it causes an oversupply at the time of supply, and conversely, when they reduce production in response to low prices, it causes a shortage (see the entry on "spider web theory"). This is often seen in livestock products, such as the egg cycle, which lasts 2 to 3 years, and the pig cycle, which lasts 4 to 5 years (in the United States there is a cattle cycle, which lasts about 10 years). However, for vegetables and fruits, price fluctuations due to good or bad yields are large. ...
