The Australian economy is constantly affected by technological, demand and policy shocks from home and abroad. The opportunities and challenges presented by these shocks create demand for government advice on the likely effects on households, firms and the Australian economy, and in turn appropriate policy responses.
Treasury has developed a multisector dynamic general equilibrium model to meet this need – the Treasury Industry Model (TIM). As a general equilibrium model, TIM captures the economy’s interconnectedness and rich industry detail, enabling the net effects of policy or other exogenous changes to the economy to be assessed.
TIM extends previous Australian models by incorporating forward‑looking agents that are able to respond rationally to policy and technological changes, a well‑defined balanced growth path defined endogenously, and a model‑consistent welfare measure. These features, combined with TIM’s significant production and industry detail, position the model well for informing advice on a range of industry‑ and trade‑related policy questions.
