What is one way a market economy effects the lives of private citizens ?

The correct answer is citizens can change jobs relatively easily.

A market economy is one in which citizens have significant freedom of choice. This is due to a lack of government intervention within an economy. In a market economy the products businesses make, the decisions on what to purchase, and how to use resources are left all up to the individual. This is why the first statement is correct, as all of the other options are part of a command economy (one in which the government makes decisions for the people).

when a country suffers, for example, a drought period, the market product is affected for a low offer, in this case, potatoes; the government has to tax to the households, which have to give more money for the potatoes which they consume, that situation make them consume substitute goods even through loans, it could increase the financial market movement and the inflationary phenomena, the business has to increase salaries in order to the employees could buy a more expensive food (potatoes) and in order to inflation tha business had to buy expensive supplies in the factor market, while the rest of the world have to gain more money to consume the same amount of potatoes.
