STATISTICAL ANALYSIS OF THE ANNUAL AVERAGE F.O.B. PRICES 
 OF CALIFORNIA CANNED APRICOTS, 1926-27 to 1936-37 
 
 H. R. Wellman U 
 
 The purpose of this report is to present the results of an analysis of the 
 major factors which have influenced the annual average f.o.b. prices received for 
 canned apricots by canners in California from 1926-27 through 1936-37. 
 
 It should be clearly recognized that the results presented herein explain 
 only what has occurred. They do not forecast what will occur in the future. The 
 analysis is intended merely as a guide to those interested in estimating either 
 the probable price at which a given quantity of canned apricots can be sold or the 
 probable quantity of canned apricots which can be sold at a given price under 
 specified conditions. 
 
 In this analysis the average relationships which prevailed from 1926-27 
 through 1936-37 between the f.o.b. prices of canned apricots and two factors were 
 measured. These two factors are (l) total shipments of California canned apricots, 
 and (2) index of prices of competing canned fruits. It should not be assumed that 
 these two factors were the only ones which affected the annual average f.o.b. 
 prices of canned apricots from 1926-27 through 1936-37, or that they are the only 
 ones which will affect the average f.o.b. prices during the coming years. Neither 
 is it certain that the relationships between the f.o.b. prices of canned apricots 
 and the factors measured will be the same in the future as they wore on the average 
 during the period covered by the analysis. 
 
 The index of prices of competing canned fruits reflects not only changes in 
 the supplies of canned peaches, canned pears, and canned pineapples from year to 
 year, but in addition it takes into account changes in the supplies of other pro- 
 ducts which compete with canned fruits and also changes in the buying power of 
 consumers. It would, therefore, be a duplication to include these factors in the 
 analysis after having already used an index which reflects them. For reference 
 purposes, however, the shipments of canned peaches, canned pears, and canned pine- 
 apples, and the index of urban consumers' income in the United States are given in 
 table 5.

 Col. 1: Compiled from reports by canners. Prices are 
 weighted average prices received by canners, f.o.b. cannery 
 or dock, for all grades and sizes of cans on an unadvertised 
 basis. Regular brokerage, cash discount, swell allowance, 
 label allowance and case allowance are included.

Fig. 1. — California canned apricots: Average f.o.b. prices 
 received by canners related to (a) shipments of canned apricots, and 
 (B) index of prices of competing oanned fruits, 1926-27 to 1936-37. 
 
 On the average (A) an increase in total shipments of canned apricots 
 from 2,500,000 cases to 3,000,000 cases has been accompanied by a decrease 
 of 21 cents a case in the average f.o.b. price, and vice versa; and (B) 
 an increase in the index of competing canned fruit prices from 70 to 80 has 
 boon accompanied by an incrjaso of 59 cents a case in the a-vorago f.o.b. 
 prico, and vico vorsa.
