Workers live longer, are healthier, many indicate they would like to continue to work: Will they be able to?,Labor Demand through Hiri

6、ns,Is there differential hiring by age? If so, what can explain this differential hiring? Answers (from my labor market experiment): Yes, younger workers in both cities studied are more than 40% more likely to be called for an interview than older (similar to findings on race and gender). No evidenc

11、perimental Setup,Resume Audit (Correspondence review) Sent resumes with different ages (as indicated by date of high school graduation) to job openings and measured the response rate by age. 40 want ads per week per city 10 “call-ins” per week per city Sent two resumes per job 3996 firms total: abou

12、t 4000 observations for each city,Setup Cont.,Cities: Boston, MA and St. Petersburg, FL Looked only at women Linda Jones and Mary E. Smith Ages listed: 35, 45, 50, 55, 62 Realistic work histories (last 10 years only) Recent work experience in very entry-level positions,Setup Cont.,Targeted only “ent

Examples: Clerical work, customer servic

Somerville) High schools chosen from small Midwestern college towns (DeKalb, IL and Ames City, IA),Results for differential hiring,Two kinds of responses measured Positive or “call

16、-back” Interview Response rate overall of: 8% in MA and 10% in FL Response rates differ somewhat by method of application. Want ads are more likely to get positive responses than call-ins. Faxes slightly more likely than emails. Results are similar with interview requests. Reminder: observable chara

17、cteristics are roughly the same in proportion for each age (by design),Tests for differential response by age,Age is correlated negatively with the likelihood of being called back or being interviewed. Significant for the interview variable. In MA: Every 10 years of age translates to an employee hav

18、ing to send out 1 more ad to receive a callback and 3 more ads to receive an interview In FL: Every 10 years of age translates to an additional 3.5 ads for a callback and 4.5 more ads for an interview,Tests for differential response by age,Split into two groups: Older and Younger, where Older = 50+

19、tests on positive and interview responses by younger and older For positive, there is a difference of 1.5 pct pt, this is a difference of 20% in MA and 1.3 pct pt and 15% in Florida For interview, these differences are 1.6 pct pt and 44% for MA and 1.8 pct pt and 43% for FL,Older/Younger Cont.,Trans

20、lation (on average): In MA, a younger seeker needs to file 11 ads to get one callback; an older, 13. A younger seeker needs to file 19 ads for one interview request, an older, 27. In FL, a younger seeker needs to file 9.6 ads to get one callback; an older, 11. A younger seeker needs to file 16.4 ads

21、 for one interview, an older, 23.,Welfare Implications from the BOE*,Reminder: FL = demography of the future Hurt depends on occupation, location To get one interview, # applications FL Average: 17 ads younger, 24 ads older FL Healthcare: 5.5 ads younger, 10 ads older MA Clerical: 32 ads younger, 72

22、 ads older # ads in paper each week varies by occupation Ex: In one week in FL: 32 LPN ads, 8 pre-school In general, half of ads are repeats from previous wk Assume 7-10 interviews to land a job (optimistic),* Back of the Envelope,BOE and Welfare Cont.,Occupational differences in time to job License

23、d Practical Nurse Younger: an offer in a week Older: 3 weeks Clerical Younger: 3-5 weeks (all new ads), 6-10 weeks (half repeats) Older 7-10 weeks or 14-20 weeks May be even longer, since within a 5 month period there are more repeat ads = Real welfare effects for low savings seekers,Is there Differ

24、ential Hiring? Conclusion,Yes, there is differential hiring by age. The effects are slightly stronger in MA than in FL and are stronger for interview requests than for callbacks. These results are similar to those found for race and gender.,Reasons for Differential Hiring: Background,Different polic

Found for: Computer skills, but only in MA Volunteering, may imply up to date work skills or good health In general, resume characteristics matter more for younger seekers Could be reverse statistical discrimination, more likely employers read younger resumes more car

However, as a whole, they do matter.,Test for Employer Discrimination,Look at companies with and without separate human resources departments HR

Conclusion,No evidence for taste-based discrimination Probably not employer-based Probably not consumer-based Evidence not as strong against employee-based Some evidence for statistical dis

37、crimination Might be lack of computer skills, might be fear that work skills are rusty (evidence only suggestive) HR department evidence highly suggestive need to finish collecting HR department information to be more certain,Conclusions,There is differential hiring by age, at least in entry-level markets and against women This differential hiring may be due to statistical discrimination Any plan which requires older workers to continue working into later ages needs to consider these results,
