To date the literature on subjective well being has focused on the developed economies. We provide empirical evidence from two emerging market countries, Peru and Russia. Our resultsand in particular a strong negative skew in the assessments of the respondents with the greatest income gainssupport the importance of relative rather than absolute income differences. Among other factors, we attribute our results to shifts in reference norms and to macroeconomic volatility. Relative differences seem to matter more for those in the middle of the distribution than for the very wealthy or the very poor. Our respondents were more critical in assessing their progress vis-à-vis others in their country versus those in their community. The large and consistent gap we find between objective income trends and the subjective assessments of the upwardly mobile may have implications for the future economic and political behavior of a group that is critical to the sustainability of market policies.
