Various Tools for Exchange Rate Regime Classification

Various Tools for Exchange Rate Regime Classification

Tools for exchange rate regime classification, currently under development.

fxpegtest(model, peg = NULL, ...)

Arguments

  • model: an object of class "fxlm" as returned by fxlm.
  • peg: character with the name of the currency the target currency is pegged to. By default this is chosen to be the currency with the maximal absolute coefficient.
  • ...: arguments passed to linearHypothesis.

Details

These tools should help to automate exchange rate regime classification.

The first building block is the function fxpegtest, a simple convenience interface to linearHypothesis. It assess the null hypothesis that only the peg currency has coefficient 1 and all other currencies have coefficient 0.

Examples

## load package and data library("fxregime") data("FXRatesCHF", package = "fxregime") ## compute returns for CNY (and explanatory currencies) ## after abolishing fixed USD regime until end of 2005 cny <- fxreturns("CNY", frequency = "daily", start = as.Date("2005-07-25"), end = as.Date("2005-12-31"), other = c("USD", "JPY", "EUR", "GBP")) ## estimate full-sample exchange rate regression model fm <- fxlm(CNY ~ USD + JPY + EUR + GBP, data = cny) ## check for plain USD peg: fxpegtest(fm) ## no deviation from a plain USD peg
