INTRODUCTION

English translation pending.

CORE DEFINITION

Junshu, equal transport, replaced tribute levies with local procurement and long-distance resale of goods; pingzhun, stabilization, had the state buy when prices were low and sell when prices were high. Under Emperor Wu of Han, Sang Hongyang implemented this so the government, by its scale, became the market's largest market maker, suppressing speculators while filling the treasury and damping price swings.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Spot the spread: identify regional or temporal gaps between supply, demand, and price before committing capital. - Trade with scale: use scale to buy low and sell high, aiming to level the price waterline rather than simply profit. - Guard the boundary: keep stabilization from degenerating into rent-seeking that harms the public.

Anchor fast decisions

Instead of taxing in kind and shipping tribute, the state bought goods where they were cheap and sold where they were dear, cutting loss and capturing the margin. Stabilization funds bought in glut and sold in shortage, damping swings. Scale lets the state set the spread rather than take prices, so revenue and stability reinforce each other.
