MERIT
MERIT is a suite of integrated, spatial decision-support tools that estimate the socio-economic consequences across sectors and wellbeings associated with disruption events.
Overview
MERIT also applies to the skilled MERIT team who apply MERIT to a range of real-world problems. MERIT is a joint partnership between GNS Science, Market Economics (MEResearch) and Resilient Organisations. The combined skillsets across these organisations enable the MERIT team to apply MERIT to a range of complex and wicked problems.
This research collaboration aims to determine
- how social and economic systems are affected by disruptions
- who is affected and who is the most vulnerable to disruptions
- how can we best reduce impacts caused by disruptions
- how we create the policy conditions now that create resilient futures
- how we create a just (equitable) transition to a resilient future
To achieve these objectives, we
- create processes to apply a suite of integrated spatial decision-support tools to estimate the socio-economic consequences associated with disruption events
- evaluate disruptions through time and across space for multiple stakeholders
- capture household and business mitigations and behavioural adaptations which occur before and after an event
- provide accessible and coherent storylines and narratives around scenarios and events
The project
Measuring the economics of resilient infrastructure
Disruptions—whether caused by natural disasters or service outages—affect the socio-economic wellbeing of our communities. But the specifics of these impacts can be difficult to predict. Not knowing the actual socio-economic impacts of a particular disruption event creates challenges when making policy and investment decisions.
MERIT is a suite of tools that estimate the socio-economic consequences associated with disruption events. Disruptions are evaluated through time (covering both the event and the subsequent response, recovery and rebuild phases), across space (detailing spatial locations regionally and nationally) and for multiple stakeholders (from households to industries).

MERIT
The MERIT tool is a suite of inter-related modules.
- Inoperability MERIT – This provides data for short-run outages (between 1-day and 1-week) from localised small-scale disruption events such as electricity, gas, or telecommunication outages. It is designed to assess the economic impacts associated with small-to-medium sized disruption events. This model assumes that the economic impacts associated with disruption are limited to those felt directly and through flow-on supply chains, i.e. through delays in production and consumption activity. No price change or other market dynamics are assumed to be involved. It reports various economic aggregate impacts (e.g. output, income, value added, GDP) by industry for communities, regions and the national economy.
- Non-Spatial MERIT – This key MERIT tool is designed to assess the economic impacts associated with sizeable disruption events. It accounts for out-of-equilibrium impacts often arising from larger disruption events. These include dynamics associated with markets where supply and demand are out of kilter, causing behaviours that would not otherwise exist in normal household or business operating conditions. It reports various economic aggregate impacts (e.g. output, income, value added, GDP, factor prices, commodity process, welfare measures etc.) by industry for both the regional and national economy.
Key features of MERIT
MERIT assesses socio-economic impacts for different sizes of infrastructure outages. As an event unfolds, the suite of tools can assess the likely impending economic impact. The suite measures the nature and distribution of effects and changes as the economy recovers from the disruption. It also adds value to investment planning by assessing the socio-economic implications of any set of resilience investment options.
Instead of generating just a single dollar value at a fixed point in time, MERIT provides a high-resolution assessment across space and through time of the socio-economic consequences of infrastructure failure. MERIT considers business response and recovery options, giving an estimate of total economic loss generated. Outputs describe local, regional and national impacts. MERIT runs comfortably over a 50-year time horizon, with the first 15-years calibrated against real-world data. Over time MERIT will be developed to report across multiple capitals and impacts across different demographic groups.
Use and applications
The research collaboration encourages the ongoing development and use of MERIT for public-good research. We encourage others to develop and build upon MERIT for non-commercial purposes. Please contact one of the MERIT team if this is of interest to you.

Funder
Funder: MERIT was initially developed by the Economics of Resilient Infrastructure (ERI) team as part of a 4-year research project funded by the New Zealand government. Funding of $2.8 m for this project was granted in the New Zealand Ministry of Business, Innovation and Employment’s 2012 Science Investment Round. The project ran from 2012 to 2016. Funding is now provided through the Resilience to Nature’s Challenges National Science Challenge, other research projects, and through fees-for-service commercial applications.
