Don Bell’s Table Egg Layer Flock Projections and Economic Commentary - 2003
(This report was written by Don Bell, University of California Poultry Specialist, emeritus, under the sponsorship of United Egg Producers)
Adjusting Our Egg Price Projections to Current Real
Prices
While our accuracy of projecting egg prices in 2002
(based only upon 24 months of hatch) was acceptable, several factors affecting
supplies of a short- and long-term nature have caused our projections to fall
behind the actual market prices experienced by the industry. Flock hatch is associated with flock size and
eggs produced and, therefore egg price.
Any factor, though, which causes an interruption in
these relationships, can cause egg price projections to be less accurate. For example, egg export increases above the
“normal” level can cause short-term supply changes and therefore prices may
increase for several months during the export period and then return to their
normal relationship to supply. In early
2003, the END problem in
The United Egg Producer’s animal welfare initiative is
a third example of factors which affect the predictability of egg prices. The real effect is rather immediate for any houses
stocked at lower densities, but the effect of the lower hatch takes a longer
period to affect the formulas used in egg price projection. The transition period involved in reducing
densities will continue to the year 2008 and traditional supply/price
relationships will undoubtedly change during this period.
As we entered 2003, we immediately saw the
discrepancies between recent projections and recent real prices. For the first 7 months, real prices averaged
8.5 ¢/dozen more than our projections - even though our projections have
increased by another 6¢/dozen as a result of the reduced 24 month hatch
total.
Gene Gregory brought this to our attention recently
that egg producers can see no value in projections that are so obviously
off-the-mark. My concern was “how to make the necessary
corrections?” and “how long should the corrections last? We decided to continue to use the proven
format (24 month hatch + monthly adjustments of seasonal effects) and to add
monthly adjustments equal to the discrepancy between the most recent UB MW
monthly quotation and the original projection.
This is to be applied for the current 12-month projection. A new adjustment will be made monthly.
In January, for example, our original projection was
for 77.3¢. The actual price was 83.4¢ -
a discrepancy of 6.1¢. The adjusted
price was taken to 83.4¢ and the subsequent 11 months were adjusted at the same
rate (+6.1¢/dozen). In February, the
adjustment was +6.2¢; March was +3.8¢, and so on.
The table below lists the monthly adjustment factors
and the resulting price projections for 2003/04.

The first entry in each column (main body of the
table) is equal to the UB MW price for large white eggs. This is comprised of the 24 month hatch
effect, the seasonal effect and the adjustment. Subsequent projections down each column are
calculated the same way - with the same adjustment. Each column uses a different adjustment
(listed at the top of the table) based upon the current discrepancy between
projected (old method) and real prices.
Example: If we look at the row titled “July/2003",
we can see the history of price projections for that month. Back in January, they were 74.6¢, by April
they increased to 81.2¢, and by June they reached 85.3¢/dozen. The real price turned out to be 85.4¢/dozen.
A study of adjustment factors at the top of the table
illustrates the changing conditions in the industry which necessitate such
adjustments. In March, the adjustment
was only 3.8¢, by April, the required adjustment rose to 9.9¢, and by June, it
had risen to 12.2¢/dozen.
The new system recognizes the existence of change and
corrects for it, but it doesn’t predict change and, therefore, adjustments will
continue to be required for the foreseeable future.
