Economic concern and stability
Explanation:
The economic problem, which is sometimes considered the basic or core economic problem, argues that the available resources of an economy are inadequate to satisfy all human needs and desires. Economics involves learning how money can be distributed under inadequate circumstances.
The avoidance of undue volatility of the macro economy ensures economic stability. The economy would be seen as economically stable with fairly constant production growth and low and stable inflation.

Internal: happens on the inside.
It depends what “internal detail” do you want, but if it’s a character’s internal details it basically has to do with their thoughts, feelings, traits and what they’ve been through or experienced.
If you mean the internal detail of an object, like a house, it has to do with the number of rooms in the house, the measures, etc.
