During the fourth century, the amount of money Athenians got from the polis for volunteering to sit on a jury and for attending the assembly diverged significantly. Jury pay remained at 3 obols a day, despite inflation, while the pay given for a principal assembly eventually rose from 1 obol to 9 obols—outpacing inflation and overcompensating most citizens for their time. What demographic reconstruction of the jury can explain why the real value of jury pay never declined to the point (...) that too few Athenians volunteered? Self-reliant citizens must have dominated the jury pool, and penêtes with young adult children would have volunteered most often. Having an additional source of household labour reduced the opportunity cost of jury service for these Athenians and made their participation more resilient in the face of the declining value of pay. Citizens who faced greater opportunity costs probably participated less over time, meaning that fourth-century juries gradually became less diverse. By contrast, the growth in assembly pay can best be understood in terms of the ‘Lycurgan’ agenda of the 330s and the 320s. Greater pay helped to ensure that the assembly's newly expanded meeting place on the Pnyx was filled to capacity with citizens from all over Attica. The result was a massive spectacle that celebrated a threatened democracy and stimulated the polis economy. Since the courts lacked the same capacity for spectacle, there was no political motivation to pay jurors more. (shrink)
