This paper presents the results of an analysis designed to discover and measure the influence of the major factors that have affected the season’s price of each class of California fresh grapes—table, black-juice, and white-juice.
The total quantity of California grapes produced in any one year is determined by the bearing acreage, the environmental conditions of growth in that year, and the care expended in their culture. During any one harvesting season, therefore, the total available supply of grapes is not subject to great change. Because the supply of fresh grapes for any given season is relatively fixed it is primarily price-determining rather than price-determined. However, the two-way usage of raisin grapes has some effect upon the quantity of that class of grapes marketed fresh. Raisins take a large portion of the crop, and the relative profitableness of shipping fresh or of drying into raisins influences the amounts utilized in one way or the other. The two uses, however, tend toward equality of returns. With a relatively fixed supply for any given year, changes in price other than those accounted for by year-to-year changes in fresh shipments, therefore, are the result of factors influencing demand. Because of this fact, a large part of this study is devoted to factors which have influenced the demand for fresh grapes.5
