2. Using the Wow/ MRW model, explain why- if all countries have the same saving rates, the same depreciation rate, the same labor force growth rate and the same rate of technological progress- we would expect countries with lower levels of output per worker to have faster growth rates of output per worker in the short run.

(a) The rate of depreciation falls.
(b) The rate of technological progress rises.
(c) The production function is Cobb - Douglassf(k) = ft*, and capital's share, a, rises.
(d) Workers exert more effort, so that output per unit of effective labor for a given value of capital per unit of effective labor is higher than before.
