Other things equal, relatively poor countries tend to grow group of answer choices slower than relatively rich countries; this is called the poverty trap. slower than relatively rich countries; this is called the fall-behind effect. faster than relatively rich countries; this is called the catch-up effect. faster than relatively rich countries; this is called the constant-returns-to-scale effect.

faster than relatively rich countries; this is called the catch-up effect.

Explanation:

Also know as theory of as theory of convergence. Which assumes the GDP per capita should equalize in the future.
