This equilibrium is disturbed by an isolated event; the analysis then shows the new equilibrium to which the system moves (comparative static analysis Opens in new window, assuming all other things to be equal, the famous ceteris paribus Opens in new window clause of economic textbooks).

It is often assumed that policy makers are able to design a line of rational actions, which achieve their objectives. These assumptions facilitate the formulation of mathematical models and economic analyses.

In turn these models suggest that economic policy should be conducted in terms of predetermined goals and instruments, with policy makers pulling deftly at ‘the levels of the economy.’
