Mega-events are usually assessed in terms of the economic impact of the event itself with little attention given to the event as part of a broader process that can be investigated longitudinally. An adapted political economy model is proposed (because the mega-event is seen as essentially an economic initiative) that distinguishes three kinds of linkages. Forward linkages refer to the effects caused by the event itself. Backward linkages refer to the powerful background objectives which justify or rationalise the event. Parallel linkages are side-effects which are residual to the event itself and not directly under the control of event organisers. This longitudinal approach also distinguishes between pre-event, eventand post-eventimpacts so that unintended and unanticipated consequences can be identified. The model is applied to the issue of displacement as a parallel linkage and to other issues of housing and impacts on neighboring communities to the mega-event site.Itis concluded that impact assessment ought to be part of every mega-event plan,and thatimpact equity and a mitigation plan to control adverse affects ought to be in place.
