Abstract
Purpose
This paper aims to examine the impact of a reduction in tick size on the information content of the order book by using data from the Taiwan Stock Exchange (TWSE).
Design/methodology/approach
To estimate the information content of the order book, the modified information share proposed by Hasbrouck and extended by Lien and Shrestha is used in this paper.
Findings
The empirical results show that the limit order book is informative. Furthermore, the results indicate that a reduction in tick size will decrease the information content of the order book and the decrease in the information content of the order book is positively related to the thinner order book.
Originality/value
This paper suggests that, in order to enhance the information content of the order book, the TWSE should disclose the full limit order book.
