Non-spatial MERIT Model Non-Spatial MERIT is the key MERIT tool. It is designed to assess the economic impacts associated with sizeable disruption events. It is unique in that it accounts for out-of-equilibrium impacts often arising from larger disruption events. These include dynamics associated with markets where supply and demand are significantly out of kilter, causing behaviours that do not exist in normal household or business operating conditions. It reports various economic aggregate impacts (output, income, value added, GDP, balance of trade, exchange rate, commodity, labour and capital prices, and various welfare measures) by industry for both the regional and national economy.
