This paper studies the relationship between public education and pay-as-you
-go social security in a representative democracy, where the government rea
cts both to voting and lobbying activities of workers and pensioners. While
an intergenerational conflict prevails concerning actual social security c
ontributions, workers may prefer public education for its positive effect o
n later pension benefits. Population aging diminishes the relative lobbying
power of pensioners, leading to a higher contribution rate, educational ex
pansion, and higher per capita income growth. JEL classifications: D72, I28
