• Dynamic Consumer Cash Inventory Model

  Staff Working Paper 2025-22 Kim Huynh, Oleksandr Shcherbakov, André Stenzel

  We study consumer cash inventory behavior by developing a dynamic model of forward-looking consumers and estimating structural parameters of the model using detailed consumer survey data. Consumers facing holding and withdrawal costs solve a discrete-time continuous-control dynamic programming problem to optimally use cash at the point of sale.

• 2024 Methods-of-Payment Survey Report: Cash in an Era of Alternatives

  Staff Discussion Paper 2025-12 Marie-Hélène Felt, Anna Chernesky, Angelika Welte

  We present core findings from the 2024 Methods-of-Payment Survey, highlighting results from both the survey questionnaire and three-day shopping diary. Although cash holdings have increased in nominal terms, we find that cash usage remains unchanged since 2020. Mobile and other alternative payment methods continue to grow in importance.
