“…An alternative to this rather simple approach is to postulate some parametric specification for 8t in terms of lagged 6t, /,, o, and any other relevant variables and use the maximum likelihood technique to estimate (/,, oa-, 58) conditional on this model for 8t. A similar approach was followed by Seitz (1988) and Kanoh and Li (1990) with varying degrees of success. For instance, Seitz (1988) did not find the threshold to depend on either the level or the variance of inflation.…”
