This paper focuses on organizations' abandonment of strategy, which ma
y be driven jointly by contagion and competition from other organizati
ons. This paper treats both explanations but emphasizes contagion. I a
rgue that strategy abandonment is contagious because the future perfor
mance of current and alternative strategies is highly uncertain, causi
ng decision makers to examine the actions of other organizations in th
e industry for clues to the correct action. Contagion from organizatio
ns easily observed by the focal organization is stronger than contagio
n from other organizations, causing corporate links across markets to
become important routes for the contagion of strategy abandonment. Thi
s theory is tested on a sample of radio stations abandoning a strategy
and is supported by evidence that contagion of abandonment occurs thr
ough the influence of an organization's social reference groups.
