The fundamental theorem of asset pricing with and without transaction costs

Mathematical Finance, Volume 35, Issue 2, Page 567-609, April 2025.
Abstract We prove a version of the fundamental theorem of asset pricing (FTAP) in continuous time that is based on the strict no‐arbitrage condition and that is applicable to both frictionless markets and markets with proportional transaction costs. We consider a market with a single risky asset whose ask price process is higher than or equal to its ...

Agents' Behavior and Interest Rate Model Optimization in DeFi Lending

Mathematical Finance, EarlyView.
ABSTRACT Contrasting sharply with traditional money, bond, and bond futures markets, where interest rates emerge organically from participant interactions, DeFi lending platforms employ rule‐based interest rates that are algorithmically set. Thus, the selection of an effective interest rate model (IRM) is paramount for the success of a lending protocol.

Macroscopic Market Making Games

Mathematical Finance, EarlyView.
ABSTRACT Building on the macroscopic market making framework as a control problem, this paper investigates its extension to stochastic games. In the context of price competition, each agent is benchmarked against the best quote offered by the others. We begin with the linear case.

The Economic Effects of ‘Excessive’ Financial Deepening

Oxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT We study the causal implications of high levels of financial deepening for economic development and banking crises in a panel of countries over the past seven decades. We adopt a factor‐augmented heterogeneous difference‐in‐differences estimator and find, in contrast to the existing literature, that very high levels of financial development do

Reconstruction of an orbital fracture in a mare using a 3D‐printed patient‐specific implant

Veterinary Surgery, EarlyView.
Abstract Objective To describe surgical repair of an orbital wall fracture communicating with the caudal maxillary sinus using a three dimensional (3D)‐printed, patient‐specific implant (PSI). Study design Case report. Animal A 25‐year‐old Haflinger mare (370 kg). Methods The mare presented with severe chemosis and emphysema of the left upper and lower
