The Cohen effect

Nationally, the social-democrat PvdA did much better last Wednesday than in 2010, but in Amsterdam growth was small. A plausible explanation is the Cohen effect: in 2010, many Amsterdammers voted Job Cohen; as a result, there was little room for improvement for the PvdA this year. An analysis confirms that the PvdA did indeed perform relatively well in Amsterdam in 2010, at the expense of smaller parties GL, D66, PvdD and SP.
