is the expected rate of devaluation. The rate can be proxied by when|
exchange parity is not preannounced but should be proxied by

|πt||is the annualized rate of inflation calculated as (log WPIt - log WPIt-12).|
|Gt||is the ratio of government deficit (IMF, IFS, line 80, multiplied by -1 so that a + indicates a deficit) as a ratio of GDP. Since there are no available monthly or quarterly data for GDP, it had to be interpolated from yearly figures (IMF, IFS, line 99b).|
