The present study uses a dynamic multiregional computable general equilibrium (CGE) model to estimate the micro- and macroeconomic effects of a hypothetical disease or pest outbreak. Our example is a Karnal bunt incursion in wheat in Western Australia. The extent of the incursion, the impact of...

Agricultural land protection (ALP) is a standard policy response to growing food security concerns driven by urbanisation, population growth and uncertainty over climate change. However, if not supported by rigorous analysis, at least in terms of the correct scale of protection, ALP may result...

Intertemporal CGE models allow agents to respond fully to current and future policy shocks. This property is particularly important for trade policies, where tariff reductions span over decades. Nevertheless, intertemporal CGE models are dimensionally large and computationally difficult to...
