Optimal Fees for Geometric Mean Market Makers

چکیده

Constant Function Market Makers (CFMMs) are a family of automated market makers that enable censorship-resistant decentralized exchange on public blockchains. Arbitrage trades have been shown to align the prices reported by CFMMs with those external markets. These impose costs Liquidity Providers (LPs) who supply reserves CFMMs. Trading fees proposed as mechanism for compensating LPs arbitrage losses. However, large reduce accuracy and can cause deviate from desirable asset compositions. CFMM designers therefore faced problem how optimally select attract liquidity. We develop framework determining value supplying liquidity when underlying process follows general diffusion. Focusing popular class which we call Geometric Mean (G3Ms), our approach also allows one optimal maximizing LP value. illustrate methodology showing an mean-variance utility will prefer G3M over all alternative trading strategies zero.

Optimal Client Recommendation for Market Makers in Illiquid Financial Products

The process of liquidity provision in financial markets can result in prolonged exposure to illiquid instruments for market makers. In this case, where a proprietary position is not desired, pro-actively targeting the right client who is likely to be interested can be an effective means to offset this position, rather than relying on commensurate interest arising through natural demand. In this...

Bandit Market Makers

We propose a flexible framework for profit-seeking market making by combining cost function based automated market makers with bandit learning algorithms. The key idea is to consider each parametrisation of the cost function as a bandit arm, and the minimum expected profits from trades executed during a period as the rewards. This allows for the creation of market makers that can adjust liquidi...

Optimal Active Management Fees

We consider the problem of a mutual fund manager that maximizes the present value of expected fees and has to decide the level of fee to impose on the fund. The fee will be paid by a risk averse investor that maximizes expected utility over final wealth. This investor can invest either in an indexed fund or in a managed fund. The manager has superior ability and, as a result of it, the fund off...

Optimal Power Mean Bounds for the Weighted Geometric Mean of Classical Means

For p ∈ R, the power mean of order p of two positive numbers a and b is defined by Mp a, b a b /2 , for p / 0, and Mp a, b √ ab, for p 0. In this paper, we answer the question: what are the greatest value p and the least value q such that the double inequality Mp a, b ≤ A a, b G a, b H1−α−β a, b ≤ Mq a, b holds for all a, b > 0 and α, β > 0 with α β < 1? Here A a, b a b /2, G a, b √ ab, and H a...

Electronic Market-Makers: Empirical Comparison

Market-makers have been used by global stock exchanges as well as prediction markets to maintain liquidity and orderly price transitions in the financial markets. We use an agent-based model of the financial markets to analyze the behavior of market-makers employing various strategies. We empirically evaluate the performance of the market-makers in the financial market to demonstrate the streng...
