An article in the Economist about economic
growth in Africa contains the following
statement:
One [of the big drivers of Africa’s growth]
is the application of technology. Mobile
phones have penetrated deep into the bush.
More than 600m Africans have one; perhaps
10% of those have access to mobileinternet
services. The phones make boons
like savings accounts and information on
crop prices ever more available.
Use the AK growth model to explain how this
technological change will affect the growth rate of
real GDP per capita in Africa.
