From the abstract:
This paper investigates the effectiveness of a game-of-chance-based bonus reward system in reducing employee absenteeism. Starting in June 2002, a Dutch manufacturing firm held a monthly lottery for workers who had taken no sick leave in the previous three months and had not previously won the lottery. In a given lottery, each of seven randomly chosen contestants received 75 Euros. The authors find statistically significant differences in absence patterns across groups of workers with different eligibility statuses depending on their attendance records and whether they had previously won. One finding is that absenteeism rose among workers who, having won already, were ineligible for further participation. Nevertheless, and although the reduction in firm-wide absence associated with the lottery drifted from 2.4 percentage points to 1.1 percentage points after seven months, the authors conclude that the lottery was of net benefit to the firm.
