What system of government calls for a free market economic system and a
government elected by the people?

Republic

Explanation:

Government officials are elected by the citizens of the country. The officials in turn keep to the agenda that they promised, and carry out what the citizens "want" (which is why they elected him for). A republic also uses the free market economic system, which means that prices & amount of goods depend on the amount of consumers, & the quality depends on competition from other companies.
