In qpmR: Quarterly Projection Models for Monetary Policy Analysis

Impulse response functions

Description

Impulse response functions

Usage

irf(x, ...)

## S3 method for class 'qpm_solution'
irf(x, shock = NULL, horizon = 24, size = NULL, vars = NULL, ...)

Arguments

x	A qpm_solution from qpm_solve().
...	Passed to methods.
shock	Shock name(s); default all shocks.
horizon	Number of quarters after impact.
size	Shock size(s). Default is one standard deviation (from the model's sigma); a named vector or a single number can override.
vars	Variables to include; default all declared (non-auxiliary) variables.

Value

A data frame of class qpm_irf in long format with columns shock, variable, horizon, value (deviations from steady state). Printing shows peak effects; plot() draws panel charts.

Examples

sol <- qpm_solve(qpm_template("bkl"))
ir <- irf(sol, shock = "eps_i", horizon = 16)
ir
plot(ir, vars = c("pi", "y_gap", "i", "q"))
