Mathematical Economics:
(a) Provide an economic interpretation of the formula (*) (b) Use the chain-rule formula) to compute the total derivative dY/dt of national output with respect to time given the functional forms Y(g, K), g(t), and K(t) spec- ified above. Make sure to express the formula you compute for dY/dt solely as a function of t.

5. Government Spending and Long Run Economic Performance Consider the following variant of the basic growth model: We will include a government that consumes output (G) and pays for it by imposing lump sum taxes (T). The government balances its budget every period. With these modifications the model becomes: Y = A-. K.N.- N =1 Y = C, +1, +G I, =s.(Y, -T) T, = G, K,+1=K,:(1-5)+1, Suppose government spending is proportional to output. As the country grows, the government...

3 Growth Model Suppose that output (Y) in an economy is given by the following aggregate production function: Y = K + NE where Kt is capital and Nt is the population. Furthermore, assume that capital depreciates at rate 8 and that savings is a constant proportion s of income. You may assume that 8 > S. 1. Suppose that the population remains constant. Solve for the steady-state level of capital per worker. 2. Now suppose that the population grows...
