Consider a growth/development model based on the following assumptions:

a. The total output is a function of total labour force, the stock of the capital, the amount of land available, and the level of technology. b. The level of technology depends on the level of capital accumulation. c. Capital accumulation depends on profits. d. Profits are a function of labour supply and the level of techniques. e. Agriculture faces diminishing returns.

Use this model to explain the differential development of country A and B. Country A is a developed country while country B is a developing country. Build your argument very carefully using the assumptions mentioned above.
