Empirical findings concerning economic voting differ according to the level of analysis employed. A widely accepted explanation for the inconsistency between macro- and micro-level evidence of economic voting is the high degree of random variation that plagues survey data. According to this explanation, aggregation purges individual-level noise from mass opinions on policy issues and outcomes. Building on the research of Bartels (1996), we debate the validity of this explanation by demonstrating that public evaluations by demonstrating that public evaluations of the national economy vary systematically with information, media exposure, political attitudes, personal experiences and demographic characteristics. Furthermore, we show that these sources of subjective heterogeneity produce systematic biases when national economic evaluations are aggregted. This findings challenge a widely accepted notion that because error in individual-level measures (or expressions) of preferences is random, the aggregation of these individual measures ensures that they correctly represent the collective preference.
