CATSIM - Inter-industry Impact Assessment

The Inter-industry Impact Assessment model is a variation of the CATSIM model and used by the Risk and Resilience Program to help understand the effects of natural disasters.

Understanding, and preparing for, the higher-order impacts of natural disasters

Beyond the physical destruction of assets and lives, disasters may affect the economy through means such as the disruption of critical infrastructure, displacement of labor, and other interruptions to supply chain activities. For governments, firms, and households to adequately prepare for, and reduce, disaster risk, it is therefore important to understand what is referred to as the direct as well as the indirect or higher-order impact of disasters.

FAST FACTS

  • The CATSIM Inter-industry Impact Assessment module was developed in 2015 to assess the higher order impact of flood damage in Cambodia and Laos.

  • The inter-industry model expresses the time dependent nature of natural disaster impact, and quantifies the benefits of improved disaster preparedness.


About the CATSIM Inter-industry Impact Assessment

IIASA’s Risk and Resilience team has built a CATSIM module which quantifies the inter-industry impact of natural disasters. The model estimates the economic costs of natural disasters across sectors and takes into account the economy’s existing production structures and estimated disaster recovery time. The model may be calibrated using commonly available datasets such as input-output tables and users may see the economic benefit of better fiscal preparedness (faster disaster recovery). This software module has been built as part of the CATSIM framework, and may be used in policy assessment and capacity building activates. Further software development which includes interface and other visualization tools is being planned.
