     More details

    This study analyzes the effect of the tick size reduction on price discovery implemented by the Tokyo Stock Exchange in 2014 for the TOPIX100 component stocks. As for the evaluation of the effect, we categorized orders based on immediacy and executability, and compared the contribution of each to price discovery before and after the event. The estimation results show that tick size reduction changes the contribution of each order type to price discovery. The changes are a decrease in the contribution of orders to the best quote, an increase in the contribution of orders to outside the best quote, and an increase in the contribution of execution prices. Furthermore, the order types driving price discovery are different before and after the event. Before the event, orders to the best quote and orders to outside the best quote drive price discovery to the same degree, but after the event, orders to outside the best quote drive price discovery.
