Using multiple waves of two public opinion surveys and a two-way fixed effect model, this paper analyzes how people's perceptions and attitudes towards public institutions shifted with the business cycle in El Salvador during 2004-2018. It finds that individuals' levels of trust toward both the president and the municipal government are positively associated with higher levels of income at the municipality level. Income is also a strong predictor of trust in mass media, confidence in the judicial system and, to a lesser extent, trust in the national legislature but income does not affect trust in the Catholic Church. The relationship between income and trust toward the president and municipalities masks a relevant heterogeneity from a rural-urban divide as well as from differences in municipal state capacity. Further, views of income distribution fairness as well as preferences for democracy are positively shaped by municipality-specific business cycles. In contrast, neither generalized trust nor satisfaction with democracy is empirically associated with income at the municipality level.
