摘要：Australia is faced with a comprehensive package of changes to its indirect taxsystem, including the introduction of a GST. The Government's only quant-itative analysis in formulating the package employed PRISMOD, an archaicinput-output price model. PRISMOD sheds dim light on a very limited range ofpolicy-relevant variables. This article explains how PRISMOD works; this is ofcontinuing relevance because PRISMOD results are a benchmark in negotiationsconcerning the price e.ects of the tax package. Then an assessment of thepackage is made using MONASH, a comprehensive dynamic general equilibriummodel. Overall, the conclusions are negative: the package is welfare-reducingand unnecessary.
