Application Background: Retail Payment Systems

• Goal/Aspiration for Project
• Enable decision-makers to estimate consequences of disruptions to the current RPS and evaluate potential disruptions/vulnerabilities caused if the composition of the system itself changes significantly (adapting to competition, new technologies, and regulation)
• Approach/Methods/Models
• Payment Flow Model (PFM): addresses potential disruptions to the current RPS
• Platform Competition Model (PCM): addresses potential disruptions caused by a transformation of the RPS
• Status, Accomplishments, and Next Steps
• Status/Accomplishments:
• designed, implemented and tested the PFM, which represents various elements of the RPS (banks, households, businesses, etc.)
• developed an initial, causal PCM
• Next Steps:
• populate the PFM database with data for the existing RPS to enable definition and analysis of disruption scenarios and possible mitigations
• implement PFM following discussion with industry experts
• develop and parameterize the PCM and analyze its behavior
• CASoS Goals: General Capabilities
