EXcess Idle Time
Abstract
The speaker introduces a novel economic indicator, named excess idle time (EXIT), measuring the extent of sluggishness in financial prices. Under a null and an alternative hypothesis grounded in liquidity and asymmetric information theories of price determination, the speaker and his research group derive a complete limit theory for EXIT leading to formal tests for staleness in the price adjustments. In agreement with changing levels of liquidity, empirical implementation of the theory shows that financial prices are often more sluggish than implied by the (ubiquitous, in continuous-time finance) semimartingale assumption. EXIT provides, for each trading day, an effective proxy for the extent of illiquidity which is easily implementable using transaction prices only. Using EXIT, a sizeable compensation for long-run illiquidity risk in market returns is uncovered.
