The lower tillage intensity in Africa may simply reflect the abundance of land: in order to maximize labor productivity, people work thinly over a large area. Under the substitution view, the profitability of mechanization and its contribution to economic growth depend on the opportunities available to workers (and sometimes draft animals) released from their tasks.
A third effect, discussed in detail in the next section, is that higher capital costs produce a bias in mechanization toward power-intensive operations. Finally, higher capital costs influence the design of machines; if repair costs are relatively low, designs emphasize repair over durability.
