Question
Consider the OLG model with the following specifications: Let the utility of household i of cohort t be c i ( t ) + c
Consider the OLG model with the following specifications:
- Let the utility of household i of cohort t be
ci(t) + ci(t + 1)
where 0 < < 1.
- Preferences are the same across individuals and across generations.
- Also, let Y (t) = K(t)H(t)1.
- The depreciation rate is 100%: = 1.
Questions
a Find the function G where
K(t + 1) = G(K(t)).
(Show your work.)
Additional specifications: Let us make the following assumptions:
- There is no population growth: N (t + 1) = N (t) t.
- Each young person in the economy works for hy = 10 hours, while each old person works for ho = 5 hours:
hi = hi(t), hi(t + 1) = [hy, ho] = [10, 5], (i, t).
- Let = 0.8, = 0.5 and K(0) = 0.25.
- Find K(1).
- Calculate Y (1) using the income and expenditure approaches.
d) Suppose that due to the public health measures, the labor endowment of old people h0 is increased strating from t = T . Using the model, discuss how this change will affect the steady state wage w and consumption of young and old workers cy and co. Explain why these changes occur.
