PENSIM output file .ECI

--- .ECI file contains lifetime saving statistics for an exemplary 
         cohort individual.

The PENSIM runNNNNN.eci file has no heading lines and no summary lines.  
The file contains scenario-specific saving information about an exemplary
cohort individual whose assumed attributes and saving behavior is specified
in the ECI table of the PENSIM input database.

FORMAT OF EACH ROW:
The statistics on each line are separated by the tab character.  
(1) scenario: scenario number
(2) ECI.id: same for each scenario
(3) balance: in saving account at start of year when age is ECI.apurch_age,
      expressed in thousands of SSASIM:COHORT.cpi_year dollars
(4) gender: female, male
(5) annuity_price: paid by exemplary cohort individual, expressed as the
      number of dollars required to buy an inflation-indexed annuity paying
      one real dollar per year
(6) annuity_payment: made in the first year when age equals ECI.apurch_age,
      expressed in thousands of SSASIM:COHORT.cpi_year dollars (note that
      the first payment is indexed for inflation so that spending a balance
      of $750K at price $15 produces a contract with face value $50K which
      pays in the first year $50K times one plus the rate of inflation)
(7) replacement_rate_denominator: expressed in thousands of 
      SSASIM:COHORT.cpi_year dollars (ECI.ssa_rr_den, ECI.psg_rr_den, and
      ECI.crs_rr_yrs control the kind of denominator calculated)
(8) balance_ratio: is balance (3) divided by denominator (8)
(9) replacement_rate: is annuity_payment (7) divided by denominator (8),
      expressed in percentage terms
