“…In selecting policies, representatives typically care not only about winning, but also about their actions while in office, either through their own policy preferences or else in terms of the "effort" expended on their constituents' behalf. With the exception of Barro (1973), electoral accountability models assume some form of incomplete information is present: either the motivations of the representatives are known but their influence over policy, and hence over voter utility, is not (Ferejohn 1986, Austen-Smith andBanks 1989), or their influence over policy is known but their motivations are not (Reed 1994, Duggan 2000, Bernhardt et al 2004, Meirowitz 2007, or neither is known (Rogoff 1990, Banks and Sundaram 1993, 1998, Coate and Morris 1995, Fearon 1999. To date, all of this work has maintained the original Downsian assumption of a unidimensional policy space, conceptualized either as a space of effort levels or as an ideological dimension.…”
