Ava Labs x CBER Ep 3: Just-In-Time Liquidity At Decentralized Exchanges

About this episode

This episode discusses a phenomenon known as Just-In-Time Liquidity at Decentralized Exchanges. Agostino Capponi (Columbia University) explains that, while this phenomenon is generally viewed as positive for liquidity demanders, it can actually undermine liquidity provision. More specifically, JIT liquidity providers can pick-and-choose the best trades, which reduces the incentive for passive liquidity providers to offer liquidity. The consequent reduction in passive liquidity can lead to lower overall liquidity.

Ava Labs x CBER Ep 5: Loss-Versus-Rebalancing (LVR) at Decentralized Exchanges

This episode discusses the costs of liquidity provision at Decentralized Exchanges. Ciamac Moallemi (Columbia University) explains that liquidity providers at a Decentralized Exchange always face a loss relative to an asset portfolio that actively rebalances to match the asset weighting of the Decentralized Exchange at all times. This loss, known as Loss-Versus-Rebalancing (LVR, pronounced 'Lever'), is the primary cost of liquidity provision. Design refinements to mitigate this cost are discussed.

Ava Labs x CBER Ep 4: Economics of Lending Platforms

This episode discusses lending platforms on blockchains. Thomas Rivera (McGill University) and Quentin Vandeweyer (University of Chicago) explain that lending platforms generate sub-optimal welfare due to under-utilization of funds that are lent to the platform. To provide more context, lending platforms are specified in such a way that the level of borrowing (relative to lending) necessarily fluctuates with market conditions, resulting in instances where borrowing is significantly below lending. Importantly, when borrowing is significantly below lending, the total interest accrued from borrowers (relative to lending volume) is necessarily low, yielding low interest rates for lenders and thereby discouraging lending. Potential improvements for lending platforms are discussed. Paper: Equilibrium in a DeFi Lending Market
