Series range: 0.088 € – 0.118 € · 35 GRD

The wrap of the period, at the historical series price. The price may be documented or estimated, as explained in the year’s sources.

Range from price bounds: 725–972 period gyros/month

How is it calculated?

Base series · period gyros/month · scenario start 1998

85.52 € ÷ 0.103 € ≈ 830 period gyros/month

After contributions, before income tax. Annual income divided by 12, using 14 payments throughout the series. Wage and contributions are twelve-month means. Purchasing power in period gyros.

The quotient is rounded to a whole number.

Only the price varies within its published bounds. Wage and composition stay fixed. This is neither a total uncertainty range nor a statistical confidence interval. Bounds come from the model's selected percentage band.

Price anchor

The series uses an anchor for this year. The entry may include rescaling or time weighting. It does not certify a national sample.

Grivetti's narrative and expense ledger agree on 35 GRD for one sandwich purchase. They describe the same purchase, not two independent observations. The series retains this single observation. The purchase date, 26 June 1984, was read in the published journal pages. Neither the book's 2015 publication nor the drachma/dollar ratio is used to date the purchase. The narrative places the purchase in Athens' Plaka/Monastiraki, without a shop name. A single central-Athens purchase is not a national sample. A bread sandwich is described, ordered without the usual onions and tomatoes. Pita, meat type, gyro and cooked weight are unspecified. Matching it to a gyro pita remains conditional.

Anchors used by the calculation: 1984

The era view applies no meat-weight or composition rescaling to a classic product.

What do the sources support?

B: Regulated, single-source or an estimate with a range

Categories describe how the price enters the model. They do not certify original-source verification, representative sampling or historical product composition.

Historical meat weights and changes in composition are model assumptions, not a series of market measurements. The assumed peak and decline in portion size need verification. The present-day weight defines the reference product. The era price refers to the wrap sold at the time; the classic price and weight-adjusted index depend on these assumptions.

Which findings hold up?

We combine 2 wage bases, 4 historical-price choices and 7 composition specifications across 50 completed years, 1976–2025.

Counts are not probabilities. Payroll reconstruction remains under review. Portion scenarios are not measurements; geography and sale channel stay fixed.

8 distinct combinations. Portion assumptions do not affect this measure.

1984 rank: 1–2 out of 50 years.

Rank one is the highest purchasing power. Published baseline: rank 2.

Minimum–maximum across cases: ≈820–855 per month.

Extremes of the selected specifications, not an uncertainty interval. Ranks precede rounding of displayed counts.

Price anchor. The series uses an anchor for this year. The entry may include rescaling or time weighting. It does not certify a national sample.

The era price is an input or calculation in the series. Comparison in classic gyros adds assumptions about weight and composition.

From source to series price

A source entry is not always the final price. These are the inputs retained by the model, without implying fresh verification of the original.

  1. 1. Amount before rescaling

    Not separately recorded

    The recorded original amount before any rescaling. It may be a regulated ceiling or composite input, not an individual purchase.

  3. 3. Period price in the series

    0.103 €

    The final price used for period purchasing power. Classic composition rescaling is a separate subsequent step.

In some years an anchor constrains the range rather than replacing the calculated price. Historical amounts use the fixed drachma-to-euro conversion, without inflation adjustment.
