How much would winning the lottery affect your labor supply?
But how big are these effects? Are income effects big or small? Would you change how much you work if given $15,000 a year for 20 years? What about $80,000 a year for 20 years?
The beauty of the lottery is that winning is random, so we can actually investigate the magnitude of these effects given appropriate data. Guido W. Imbens, Donald B. Rubin, and Bruce Sacerdote performed such an analysis using a data from a survey of 496 Massachusetts lottery winners. They found:
winning $15,000 a year for 20 years would not have a major effect on your life. However, if you instead won $80,000 a year for 20 years, it would affect your labor force participation, automobile expenditures, the value of the home you own, and your savings, according to the study.Imbens, Rubin, and Sacerdote, in Working Paper 7001 from the National Bureau of Economic Research, analyzed a survey that they conducted of 496 Massachusetts lottery winners. The survey participants were divided into three groups: winners of one-time prizes between $100 and $5,000; winners of a yearly amount of less than $25,000 for 20 years, with an average annual prize of $15,000; and winners of at least $25,000 a year for 20 years with an average prize of $80,000 annually.
The researchers found that a prize of $15,000 a year had little effect on the labor supply of the winners. However, they also found that winning $80,000 rather than $15,000 reduced labor supply significantly. Additionally, estimates by Imbens, Rubin, and Sacerdote indicated that, in this case, car values rose (by at least $5,500 on average), home values increased (by $30,000 on average), and savings went up (especially in the form of bonds and mutual funds).
