Governments can command (rules, bans, standards) or harness markets (taxes, permits, subsidies). Each instrument has a record, and the failures - free riders, carbon leakage - are as instructive as the wins. This is the real knowscape from knowhere, not a picture of one. Drag it. Watch what actually changes.
Every policy here is one lever aimed at one target — demand, prices, inequality, the environment — and every lever has a lag, a limit, and a side effect it can't escape. The exam never asks what a policy does; it asks what it trades away to do it.
Governments use command instruments like regulations and bans or market-based tools like carbon taxes and tradable permits to correct environmental market failures, each with different efficiency and compliance costs.
This concept has no prerequisites in knowhere's map — it is a root. Everything in the topic is built from here.
Each one is its own knowscape in the app — built for how a particular student takes things in, not one explanation handed to everybody.
