Where Does MEV Really Come From? Revisiting CEXDEX Arbitrage on Ethereum
Bence Ladóczk, Miklós Rásonyi, János Tapolcai
A central question of the Ethereum ecosystem is where Maximal Extractable Value (MEV)revenue originates and to what extent it stems from harming unsuspecting users. It is acceptabl…
On ergodicity of the SAGA-LD algorithm
Miklós Rásonyi
The so-called SAGA-LD algorithm is used for efficient sampling from high-dimensional distributions in machine learning. Its intricate dynamics resists standard approaches of Markov…
Sharp Mixing Rates for Markov Chains on General Spaces with Unbounded Random Environments
Attila Lovas, Miklós Rásonyi, Lionel Truquet
We consider Markov chains on general state spaces in stationary random environment which are defined by a random mapping that is contractive up to a bounded perturbation. We prove…
On the existence of personal equilibria
Laurence Carassus, Miklós Rásonyi
We consider an investor who, while maximizing his/her expected utility, also compares the outcome to a reference entity. We recall the notion of personal equilibrium and show that,…
On the utility problem in a market where price impact is transient
Lóránt Nagy, Miklós Rásonyi
We consider a discrete-time model of a financial market where a risky asset is bought and sold with transactions having a transient price impact. It is shown that the corresponding…
Rate estimates for weighted total variation norm in terms of Wasserstein distances
Iván Ivkovic, Miklós Rásonyi
We study the weighted total variation distance between probability measures. Using Fourier-analytic tools, we present estimates in terms of Wasserstein distances between the respec…
