Assume that the Solow model provides an accurate representation of the two Germanies around the late 80s and early 90s. Although in 1990 both countries re-unified, for this problem we will treat them as two separate economies, and we will model the effects of the reunification as a one-time flow of resources (capital and/or labor) across the common border.
Aside from being in steady state initially, assume that before the re-unification both economies had the same saving rate, the same rates of population growth and depreciation, and that capital was equally important for production in both countries, with a common value of = 1/2.
Let's focus first on the period before the re-unification.
1. In this initial steady state, output per capita in the West was twice the level in the East, due to its higher productivity A. Use this information and equations for the steady state to calculate the ratio of productivity between the two countries. Explain your derivations.
2. Calculate the ratio of capital per capita between the two countries. Explain your derivations carefully.
3. Did the owners of capital in West Germany have any incentives to reallocate their capital from the capital abundant Western economy to the capital scarce Eastern one? Explain your answer (think about the payment per unit of capital in both countries).
4. Would East German workers have any economic incentives to migrate to the West? Explain your answer (think about wages in both countries).
