Verhulst Model In 1840, Belgian demographer Pierre Verhulst modified the Malthus model by proposing that the rate of growth dy/dt of the world’s population y(t)should be proportional to ky − cy2; thus

where both k and c are positive constants. Why do you think such a model may be feasible? What possible interpretations can you give for the term −cy2? Hint: Factor the right-hand side of the differential equation. Such refinements of population growth models will be further explored in Sec. 2.5.
