Congrats to NYC on a week of congestion pricing. Now let's make the prices dynamic.

Any attempt to plan an economy inevitably lands on these as a coordination tool.
Politics dictate how these prices (and each participant’s objective) are set: in a decentralized or centralized way.

Prices are a communication system that links supply and demand. Politics are irrelevant.

In short: optimally planning the economy is the same as optimally setting prices and then letting participants make their own decisions.

Kantorovich, of course, couldn't call these prices (the USSR had gulags), but these ideas continued to appear in economic planning problems.

In the west, these dual variables were called "shadow prices," since they measure the marginal cost (or benefit) changing a constraint has on the optimization problem objective.

Kantorovich developed linear programming in the 1930's to centrally plan the Soviet economy. His solution method relied on dual variables ("resolving multipliers"), which measure the sensitivity of each constraint.

Why solve problems when you can just virtue signal? Less effort.
