Economics' Approach to Planning

No one wants to splurge today and starve tomorrow, nor do the opposite.

Life-cycle consumption smoothing—balancing our living standard through time—
is the goal. But finding the right current and future spending targets to achieve that goal is a complex mathematical problem.

Economists have worked on this problem for a century. Now, based on advances in desktop computing and numerical algorithms, you can implement life-cycle consumption smoothing using ESPlanner.
