Application in economics
The ratchet effect can be seen in long-term trends in the production of many consumer goods. Year by year, automobiles gradually acquire more features. Competitive pressures make it hard for manufacturers to cut back on the features unless forced by a true scarcity of raw materials (e.g., an oil shortage that drives costs up radically). University textbook publishers gradually get "stuck" in producing books that have excess content and features.
