" 20 درصد افزایش درآمد برای همه؟": اثر افزایش نسبی در درآمد بر نابرابری درآمد ادراک شده

Most research on income inequality implicitly assumes that a fixed percentage increase in income across all income levels does not alter income inequality. In contrast with this assumption, we show that relative increases in income lead to increased perceptions of inequality, even when buying power is held constant. In a second experiment, we extended these findings using a fictitious currency, thereby eliminating effects of using a familiar currency. In study 3, we demonstrate that feelings of envy and fairness are affected by a fixed percentage income increase.
