Arbitrage with financial constraints and market power
Journal of Economic Theory . 2024. Vol. 217. Article 105825.
I study how (VaR-based) financial constraints affect liquidity and welfare under different structures of the arbitrage industry. When capital is dispersed across competitive arbitrageurs, financial constraints may impair their ability to provide liquidity, lowering other investors' welfare. However, when capital is concentrated among arbitrageurs with market power, introducing constraints can make everyone better off and increase liquidity. Further, alternative constraints (fixed margins, position limits) have the same effects as VaR constraints when arbitrageurs are competitive, but not when they have market power. These results lead to new policy implications for margin and capital requirements and yield new empirical predictions.

We perform a comprehensive study of different illiquidity effects in the relatively illiquid Russian stock market. Over the period 2010–2020, we apply cross-sectional and time-series regressions using two low-frequency illiquidity proxies: the Amihud ratio and the invariance-implied ratio. The evidence suggests that implicit trading costs influence only the returns of small-capitalization stocks or low size ...
