α: calibrated so average coauthorship-adjusted count equals average raw count
This paper argues that increasing average incomes and stagnating levels of happiness, as observed in the United States since the 1970s, do not constitute a paradox. First, we show that the effect of higher incomes has been more than counteracted by changes in other socioeconomic variables, notably the prevalence of marriage and divorce. Second, we show that the effect of a given amount of real income on happiness has not changed between the 1970s and the early 2000s.
