Given the competing hypotheses proposed by Barclay and Smith
(1988) and the mixed empirical evidence as previously discussed, the
prediction of the effect of share repurchases in Thailand on liquidity
is, therefore, ambiguous. In this regard, the following hypotheses are
formulated:
H1a: Liquidity is higher on repurchasing days compared to nonrepurchasing
days.
H1b: Liquidity is lower on repurchasing days as compared to nonrepurchasing
days.
H2a: Share repurchases have positive effect on liquidity.
H2b: Share repurchases have negative effect on liquidity.
