Summary

This project is a Maple code generator for performing log-linearisation.

It is useful, for example, for macro-economists working with Dynamic Stochastic General Equilibrium (DSGE) or Real Business Cycle (RBC) models.

The project is written in C#.

Usage

The programme should be fairly self explanatory. The function signature box expects something like:

fPHILLIPS(PI, PIf, Y, Z)
fIS(Y, Yf, R, PIf, G)
fTAYLOR(R, Rp, PIf, Y, EPSILON)

which will produce output equations in

pid, pifd, yd, zd
yd, yfd, pifd, gd
rd, rpd, pifd, yd, epsilond

respectively. Note that the steady state values will be assumed to be:

PIs, PIfs, Ys, Yfs, Zs, Rs, Rps, Gs, EPSILONs

hence you would probably want to include the following Maple code in your worksheet, in order to ensure that future and past values are given the same steady state:

PIfs:=PIs; Yfs:=Ys; Rps:=Rs;
