higher

If there is a savings decrease, the country has a ______ level of steady-state capital.

lower

When do countries grow faster?

when they are farther away from their steady-state level of capital

the tendency for poorer countrues to grow faster than richer countries and thus for poor and rich countries to converge in income

conditional convergence

all countries income will converge, regardless of their steady-state level of capital (little evidence of this)

absolute convergence
