Changing Dimensionality Of The Political Issue Space: Effects On Political Party Competition
نویسندگان
چکیده
We built an agent-based model of political party competition in order to explore the effect of the decrease in the number of relevant political issues on the number of political parties and the corresponding voter shares. We find that, when the space experiences a political shock and suddenly reduces in the number of dimensions, the number of political parties declines. We also observe that, after the shock, (i) the inert parties tend to improve their performance and that (ii) a few of the adaptive large size-seekers cushion their increased mortality hazard by locating in the zone with most intense competition (close to the political space center), which generates strong party size effects.
