The project has two goals. First, to follow up the unique sequence of Swedish Representation Studies covering the years 1969, 1985, 1988, 1994, 1996 and 1998. Second, to study confidence in societal institutions with a special emphasis on the Riksdag. Voter's as well as members' cognitions and evaluations of the Riksdag and its performance will be analysed across time. Most of the analysis will be based on survey data from the Swedish National Election Studies and the SOM institute as well as from a special mail questionnaire study involving all members of the Riksdag. Part of the project is comparative. Our results will be compared with data from similar studies in The Netherlands and Germany. A special feature of the project is an experimental study of information and trust effects among school pupils visiting and not-visiting the Riksdag.
