Q1: Protecting Injured Workers vs. Encouraging Economic Development
2
Previous literature found workers very responsive to benefit levels
Increased WC receipt may increase employer costs
States seek to encourage economic development
Concern: employers will choose to locate in states with lower WC costs
MD: Max=$877/week
DC: Max=$1,233/week
VA: Max=$816/week

Follow the literature: Increase benefits 10%, see 5% more

Policy Implications
5
Workers much less responsive to benefit levels than previous estimates suggest
Can better protect injured workers (by raising maximum benefit levels) without adversely impacting economic development

PRE POST
The 99th Percentile in Distribution of Claim Duration Over TimeDays away from work
Observations are weighted by inverse of predicted probability claim has valid return-to-work information.

Identifying Assumption: Other than the bonus payment, all changes in duration
during this time period impact treatment and comparison groups in same way
Ways to test identifying assumption:1. Make sure treatment same in period before
bonus payment If groups are treated the same, coefficient estimate on POST1*INCENT
will be zero
2. Examine different comparison groups with more similar groups of injuries
Injuries with same three-digit ICD-9 code Back injuries Bruises Cuts

Standard errors are clustered by injury code. Regressions are weighted by the inverse predicted probability a claim has valid return-to-work information. Each regression includes injury, demographic, job, time, and TCM effects. Significance at 10 percent (*), 5 percent (**).

Claim duration increases between 2-2.5 weeks for severe claims
This corresponds to 30% increase in probability a claim lasts more than 15 months
![Page 12: MELISSA MCINERNEY Workplace Safety and the Economic Impact of Workers’ Compensation Insurance.](https://reader035.fdocuments.us/reader035/viewer/2022062409/5697bf9b1a28abf838c929c7/html5/thumbnails/12.jpg)
12
TCMs reduced duration by about one third of a day for minor claims
Bonus payment generated an increase in duration for severe claims: An increase of about 19 days among cash benefit claims
30 percent in probability spell lasts longer than 15 months
Potential Mechanisms:
Minor claims: reduce duration through infrastructure changes
Severe claims: Increase duration via enrollment in vocational rehabilitation

Overall Effect of Privatized Case Managers (2002)Bonus structured such that maximize profits if extend
duration
Cash benefit claims having an incentivized injury miss 18 more days
~7,000 cash benefit claims having an incentivized injury
cash benefits ~ $59 per day
=> (7,000)*($59)*(18 days) = $7.4m in additional benefits
TCMs used vocational rehabilitation to increase claim duration
265 individuals received voc. rehab. because of bonus
average cost ~ $5,000 per participant
=> (265)*($5,000) = $1.3m in voc. rehab. Costs
Bonus payment may cost state over $8.5m in additional benefits paid

Discussion
WC is an important, large social insurance program, and many policy changes were implemented in the 1990s.
Structure of bonus suggests heterogeneous responses by TCM as claim develops over time, including an increase in duration as claims with incentivized injuries approach 15-month threshold.
Evidence is consistent with these anticipated responses; duration falls by 1/3 of a day for minor claims, increases by 20 days for severe claims

Policy Implications
15
Can provide better benefits for injured workers without risking economic development goals
Take great care in contracts write with private companies—may have unintended consequences
