Why Is this Topic Relevant?
If you are calculating damages for litigation and there is an element of:
• How long a person is or was expected to live• How long a person is or was expected to work
And ...
The facts of the case and impact on damages is significant, you should consider/discuss the retaining of a life expectancy expert
5
Goals and Objectives
Life Expectancy• Define life expectancy and survival time• Identify a life table• Differentiate between mortality rates and excess death rates• Identify situations in which life expectancy is likely to be affected
Worklife Expectancy Calculations• List common methodologies used to estimate worklife• Understand the basic components of estimating worklife in two examples• Calculate customized worklife expectancies based on alternative life tables
7
Life Expectancy Misconceptions
8
Life Expectancy / Survival Time
Life Expectancy is defined as the average survival time across a large group of similar individuals.
Survival time is defined as the exact amount of time lived by an individual in days/hours/minutes.
No one on the planet can tell you what your survival time will be.
We can provide reliable information about life expectancy.

Life Table
• History
• Use in determining life expectancy
10Source: Series of Gresham lectures on 350th anniversary of John Graunt’s text.
The Life Table ‐ then
11Source: Entire Graunt text transcribed by Ed Stephan: www.edstephan.org/Graunt/bills.html
The Life Table ‐ now
12Source: Arias E (2014). United States Life Tables, 2009. National Vital Statistics Reports. Vol. 62, No. 7.
Mortality and Excess Death Rates
Mortality rate is the death rate. It measures the number of deaths per exposure time.
Excess death rate is the ‘excess’ rate of death above and beyond the general population (or study population in comparison).
The safest year of an individual’s life: Age 10 to 11
A year with very high risk: Age 0 to 1
13
Applying Life Expectancy
Examples:• Cerebral Palsy• Spinal Cord Injury• Traumatic Brain Injury• Minimally Conscious / Vegetative State • Cancer, cardiovascular disease, chronic illnesses,
and other general medical conditions
We are biological machines and our bodies are meant to be in motion. To the extent our bodies are not in motion we suffer as a result.
14
Worklife Expectancy
a measurement of the cumulative duration of remaining activity in the labor force
Worklife Expectancy = P(life) x P(activity in the labor force)
Measurement of the probability of labor force activity
15Source: Richards H, Donaldson M (2010). Life and Worklife Expectancies, Second Edition.
Concepts relevant to Measuring Lost Earnings
16
Are you measuring Expected Earnings or Earning Capacity?
Expected Earnings reflect a combination of a person’s • Abilities • Opportunities • Preferences or Choices
Earning Capacity reflects a combination of a person’s:• Abilities• Opportunities

Methods of Determining Worklife
Source: Brookshire ML, Luthy MR, Slesnick FL (2009). Journal of Forensic Economics. 21(1): pp 5‐34.
Two Methods of Measuring Worklife
19
1) Increment‐Decrement (Markov) Worklife
2) Life Participation Employment (LPE) using disability data
20
Measures the number of years of worklife adjusted only for:
• Prob. (Life) • Prob. of being active in the Labor Force
Measures the probabilities of transitioning between being in and out of the Labor Force (CPS)
Specifically measures the worklife expectancies for persons who are in or out of the labor force at the time of the incident.

LPE (Life Participation Employment)
23
Measures the number of years of worklife adjusted only for:
• Prob. (Life) • Prob. of being active in the Labor Force
(ACS & CPS)• Prob. of Employment (ACS & CPS)• Gamboa Gibson Worklife Tables look at
employment and participation rates based on disability.

26
• Life expectancy can be severely impacted in major medical conditions
• Worklife expectancy is measurement of the cumulative duration of remaining activity in the labor force
• When using worklife tables, you are making an assumption about the life expectancy of the plaintiff
• Measuring damages for an individual with a life expectancy that is significantly different from the average population can have a large impact on damages.
Takeaways
27
If all you know is age & sex and/or the person appears average for the general population
The HUGE Takeaway
If the person has a significant medical condition and/oris seriously injured
Use a condition specific life tablebased on the medical recordsand the peer reviewed literature
28
Thanks!
