Example 9.10-9.14 in Li (2019)

Description

This is Example 9.10-14 in Li (2019), which illustrates economic cycles in a monetary economy and economic policies ironing economic cycles.

Usage

Example9.10(
  policy = NULL,
  pExg = rbind(NA, NA, 0.25),
  p0 = rbind(0.625, 0.375, 0.25),
  priceAdjustmentVelocity = 0.3,
  ts = TRUE
)

Arguments

Those arguments will be passed to the function sdm. See sdm.

policy

a policy function

pExg

an n-vector indicating the exogenous prices (if any).

p0

an initial price n-vector.

priceAdjustmentVelocity

the price adjustment velocity.

ts

if TRUE, the time series of the last iteration are returned.
