2.2
Consider the following functions for a model economy:
Consumption:
C=C, +c (Y-T)
Investment:
I=1, + a Y -br
Labour Supply:
BN°
= W/P
Money Demand:
L=L, +kY - hi
Production Function: Y AK N
Tax Revenue:
T=T, +tY
All variables with a subscript 0 denotes the autonomous component, e.g. C, is autonomous
consumption. All lower-case letters (except the real interest rate r and the nominal interest rate I)
are parameters. Government expenditure (G), the money supply (M), the level of technology (A)
and capital stock (K) are all exogenously given. N is the level of labour employed. For this
economy, the general price level (P) and the nominal wage rate (W) are fully flexible. The expected
inflation is assumed to be zero.
(i)
Derive the equation that characterizes equilibrium in the goods market.
(ii)
Derive the equation that characterizes equilibrium in the money market.
