response by changing the slope of the demand schedule can thrust the model into instability, chaos, and extinction, without … via slope preserving increases in market demand can push the model into instability, chaos, and even extinction. Finally …, we show that similar adjustments in market demand may be capable of eliminating instability and chaos rooted in powerful …
