The paper offers a complex and systematic model of the bandwagon effect in
collective action using continuous time equations. The model treats the ban
dwagon effect as a process influenced by ratio between the mobilization eff
orts of social activists and the resources invested by the government to co
unteract this activity. The complex modeling approach makes it possible to
identify the conditions for specific types of the bandwagon effect, and det
ermines the scope of that effect. Relying on certain behavioral assumptions
, these conditions are only indirectly connected to individual beliefs, so
that a given bandwagon effect can be explained and planned without knowing
the exact preferences of the players' preferences.
