Universal basic income in a financial equilibrium
Kim Weston
Universal basic income (UBI) is a tax scheme that uniformly redistributes aggregate income amongst the entire population of an economy. We prove the existence of an equilibrium in…
Radner equilibrium with population growth
Jin Hyuk Choi, Kim Weston
We prove the existence of a Radner equilibrium in a model with population growth and analyze the effects on asset prices. A finite population of agents grows indefinitely at a Pois…
A multi-agent targeted trading equilibrium with transaction costs
Jin Hyuk Choi, Jetlir Duraj, Kim Weston
We prove the existence of a continuous-time Radner equilibrium with multiple agents and transaction costs. The agents are incentivized to trade towards a targeted number of shares…
Existence of an equilibrium with limited participation
Kim Weston
A limited participation economy models the real-world phenomenon that some economic agents have access to more of the financial market than others. We prove the global existence of…
Endogenous noise trackers in a Radner equilibrium
Jin Hyuk Choi, Kim Weston
We prove the existence of an incomplete Radner equilibrium in a model with exponential investors and an endogenous noise tracker. We analyze a coupled system of ODEs and reduce it…
Price impact equilibrium with transaction costs and TWAP trading
Eunjung Noh, Kim Weston
We prove the existence of an equilibrium in a model with transaction costs and price impact where two agents are incentivized to trade towards a target. The two types of frictions…
An incomplete equilibrium with a stochastic annuity
Kim Weston, Gordan Zitkovic
We prove the global existence of an incomplete, continuous-time finite-agent Radner equilibrium in which exponential agents optimize their expected utility over both running consum…
Existence of a Radner equilibrium in a model with transaction costs
Kim Weston
We prove the existence of a Radner equilibrium in a model with proportional transaction costs on an infinite time horizon and analyze the effect of transaction costs on the endogen…
Muckenhoupt's condition and the existence of the optimal martingale measure
Dmitry Kramkov, Kim Weston
In the problem of optimal investment with utility function defined on , we formulate sufficient conditions for the dual optimizer to be a uniformly integrable martingal…
Stability of Utility Maximization in Nonequivalent Markets
Kim Weston
Stability of the utility maximization problem with random endowment and indifference prices is studied for a sequence of financial markets in an incomplete Brownian setting. Our no…
