Simultaion of Nikaido's "No Grwoth, No Flutuations"

See Nikaido "Prices, Cycles and Growth"


The applet works best in Netscape

Variables


k =: Capital per capita
I/K =: Investment over capital
r =: Nominal interest rate
Speed : Internal java time sharing parameter
Time : t counter
Time Change := dt in the simulation
Phi Scale := A parameter controling ths willingness to invest
Savings := Savings rate
Money Supply : Growth rate of money (if I remeber correctly)
Labour Growth : Effective growth rate of labour
Investment spririts : Measure of willingnes to invest
tr(J)^2-4*|J| : Stability condition
Determinant : Stability condistion
Trace : Stability condition
Steady Growth k := k*
Steady Growth (I/K) := (I/K)*
Steady Growth k := k*
(k*,(I/K)*,r*) defines the values that keep k,I/K,r unchanged. A r* less then zero 0 indicates a situation where no Solovian steady growth exist

Buttons


Start : Starts the simulation
Stop : Stops the simulation
Clear Buffer : Clears all displays
Solow Steady Growth : Sets the variables to there steady growth values

Displays


3d Display : Plots the vector k,(I/K),r in 3-d
2d Display : Plots the vector k,(I/K),r in three 2-d graphs with time on the x-axis

Time mode


For faster performance unde the 3d display use 'Dynamic dt' dt will be adjusted to smaller values when any of k,I/K or r changes fast and vice versa

Example


Choose 2d Display and adjust its size
Set Phi Scale to 0.025 (click once on the right arrow)
Click on the Solow Steady Growth Button
Click Start

The simulation start in a Solovian Steady Growth State!


Click Stop
Change Phi Scale to -0.025
Click Start

The simulations start without the existence of a Solovian Steady Growth State!
