Health Economics

  • (written as Dynamics)
    One way of doing economics, in which the focus is on the process of change as people react to disequilibria arising from disturbances of various kinds affecting a model. A common interest in economic dynamics concerns whether and in what way, with what speed, etc., an economy will approach equilibrium following a disturbance. The other main way of doing economics is comparative statics, which compares the states of equilibrium that are predicted to come about in response to disturbances but not the process through which they come about.
