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 ...

Mathematical Finance, EarlyView.ABSTRACT This study develops a novel multivariate stochastic framework for assessing systemic risks, such as climate and nature‐related shocks, within production or financial networks. By embedding a linear stochastic fluid network, interpretable as a generalized vector Ornstein–Uhlenbeck process, into the production network of interdependent ...

Equilibrium Reward for Liquidity Providers in Automated Market Makers
Mathematical Finance, EarlyView.ABSTRACT We find the equilibrium contract that an automated market maker (AMM) offers to their strategic liquidity providers (LPs) in order to maximize the order flow that gets processed by the venue. Our model is formulated as a leader–follower stochastic game, where the venue is the leader and a representative LP is the follower.

Endogenous Institution Formation for Public Good Provision
The Manchester School, EarlyView.ABSTRACT We revisit an existing framework of endogenous institution formation for public good provision, incorporating heterogeneous players to address the question, “Who joins an institution that sanctions only its members to provide a public good?” We analyze two models with different sources of heterogeneity.

Tax Progressivity, Public Debt, and Growth in a Neo‐Kaleckian Model
Metroeconomica, EarlyView.ABSTRACT We develop a neo‐Kaleckian growth‐and‐distribution model featuring two classes of workers and a progressive income tax. Two fiscal closures are considered: balanced budgets and deficit financing via public debt. We study the responses to shocks, including changes in functional income distribution, and assess how tax progressivity alters demand

Metroeconomica, EarlyView.ABSTRACT We propose a demand‐led heterogeneous firm macroeconomic model to study the impact of an exchange rate devaluation on output and financial stability. We simulate the model and find that, in the presence of foreign debt, a devaluation can have contractionary effects.
