In a command economy, decisions are often made

by the government

Explanation:

The command economy is an economy type typical for the communist societies. The government is the one that controls everything in this type of economy. The private sector is absent, and the government controls all of the production and all of the resources. There is people chosen by the government that are in charge for planning how much, in what way, and what should be produced for a particular year. Unfortunately, in practice, this type of economies have turned out to be very inefficient, often being on the verge of collapsing because of bad planning, or because of over-dependence on themselves.

In command economy, decisions  are often made to achieve social and political goals.

Explanation:

A command economy is a system in which the authority spent more interest to choose decisions like 'which goods to produce', 'how much to produce' and 'at what price to sell' rather than the 'free market'.

So in a command economy the decisions are regularly made to achieve social and political goals by enlarging the financial institutions, utility companies and the manufacturing sector.

It also specifies investments and income. The command economy has an important feature of every communist society. The government manages monopolistic companies or entities deemed necessary to achieve economic goals.
