Arbitrage Incentive Efficacy

Arbitrage Incentive Efficacy measures how effectively a protocol motivates traders to buy or sell an asset to correct price deviations. In decentralized finance, this is often achieved through minting and burning mechanisms or discount windows that allow users to profit from the difference between the market price and the peg.

High efficacy means that as soon as a price moves slightly away from the target, traders immediately engage in corrective trades to capture the profit, thereby minimizing the duration of the de-pegging event. If incentives are too low or if transaction costs exceed potential profits, the efficacy drops, leading to persistent price instability.

This concept is fundamental to the stability of synthetic assets and algorithmic stablecoins. It bridges the gap between game theory and market microstructure by ensuring that rational actors act in the interest of protocol stability.
