Mimetic isomorphism and its effect on merger and acquisition activities in Taiwanese financial industries

This paper adopts an institutional theory and explores the impact of institutional pressures on mimetic isomorphism in merger and acquisition (M&A) activities. It uses 117 M&A announcements and adopts a logistic regression model to construct a probability model for mimetic isomorphism. This study finds that a firm's own M&A experiences and the frequency of M&A deals are positively correlated with the likelihood that a firm will complete its M&A deal. This paper also utilizes an event study methodology to estimate the excess return around M&A announcements as a proxy for the M&A performance and adopts the OLS regression model to analyse the relation between the imitation and M&A performances. There is a positive relation between the frequency of M&A activities and M&A performances, and a negative relation between a firm's own M&A experiences and M&A performances.
