The government can discourage the production of goods and services that create negative externality by imposing taxes. Taxes increases the cost of production and discourages production of that good.

Positive externality is when the benefits of economic activities to third parties exceeds the cost. Goods that produce postive externality are usually underproduced. The government can encourage production of goods that produce postive externality by subsidizing to encourage production.

Government fixing prices can be called either price ceiling or price floor. Price ceiling or price floor can discourage production and consumption respectively.
