the business cycles of advanced economies converged during the first third of the twentieth century.

prices in developing countries are sticky in the long-run whereas prices in advanced economies are flexible in the long-run.

the simple Solow model does not consider complementary inputs such as infrastructure and human capital.

there are significant barriers preventing international factor mobility.

Basic education should be made compulsory.

Human capital should be paid better in poor countries.

Educational subsidies are economically justifiable

Human capital would not necessarily be subject to decreasing returns in the aggregate

A longer patent period means that less knowledge will be available for use

The higher the cost of a patent application, the fewer patent applications will be made

ncreasing the cost of new knowledge through patent licensing will decrease the demand to use new knowledge.

Less than full-exploitation of new knowledge by potential users is the cost of increasing the incentive for inventors to produce new knowledge.

patents restrict access to new technologies to those nations that can afford the fees.

low human capital endowments lead to low rates of diffusion of technological innovations.

multinational corporations do not reinvest their profits from poor nations in the poor nations

all of the above.

An increase in the rate of saving (s) could lead to an increase in the rate of growth of output

Policies that would only lead to a one-time increase in the level of output could lead to a permanent increase in the rate of output growth.

The economy would not converge to a unique steady state capital to effective labour ratio.

The golden rule rate of saving would be zero.
