Tiers of joy? Reserve tiering and bank behavior in a negative-rate environment
Negative interest rate regimes typically involve reserve tiering to exempt a portion of bank reserves from negative rates. We study the effects on bank behavior of a large and unanticipated change in reserve tiering by the Swiss National Bank that generate ...
2024Flood, farms and credit: The role of branch banking in the era of climate change
Seyed Javad Kashizadeh, Pejman Abedifar
Using Iran's unexpected flood in April 2019 as a natural experiment, we show that local branches bridge the time gap between the disaster and governmental aids by immediately increasing their lending for two months following the flood. Analyzing proprietar ...
Elsevier2024EOS: Efficient Private Delegation of zkSNARK Provers
Alessandro Chiesa, Yinuo Zhang
Succinct zero knowledge proofs (i.e. zkSNARKs) are powerful cryptographic tools that enable a prover to convince a verifier that a given statement is true without revealing any additional information. Their attractive privacy properties have led to much ac ...

In this article, we review the growing literature on financial technology (FinTech) lending-the provision of credit facilitated by technology that improves the customer-lender interaction or used in lenders' screening and monitoring of borrowers. FinTech l ...
ANNUAL REVIEWS2022Dynamic Byzantine Reliable Broadcast
Rachid Guerraoui, Jovan Komatovic, Dragos-Adrian Seredinschi, Andrei Tonkikh
Reliable broadcast is a communication primitive guaranteeing, intuitively, that all processes in a distributed system deliver the same set of messages. The reason why this primitive is appealing is twofold: (i) we can implement it deterministically in a co ...

Brookings Institution2020Replicated state machines without replicated execution
This paper introduces a new approach to reduce end-to-end costs in large-scale replicated systems built under a Byzantine fault model. Specifically, our approach transforms a given replicated state machine (RSM) to another RSM where nodes incur lower costs ...
IEEE2020Improved Credit Bounds for the Credit-Based Shaper in Time-Sensitive Networking
Jean-Yves Le Boudec, Eleni Stai, Ehsan Mohammadpour
In Time-Sensitive Networking (TSN), it is important to formally prove per-flow latency and backlog bounds. To this end, recent works have applied network calculus and obtained latency bounds from service curves. The latency component of such service curves ...
2019Secure Contactless Payment
Serge Vaudenay, Handan Kilinç Alper
A contactless payment lets a card holder execute payment without any interaction (e.g., entering PIN or signing) between the terminal and the card holder. Even though the security is the first priority in a payment system, the formal security model of cont ...
