Goals:

Agricultural products are linked from farms to consumers through food marketing systems such as food manufacturing, wholesaling, and retailing. At each level of marketing system, the cost of marketing services are added, such as transportation, processing, packaging, distribution of farm products and marketers’ margin. This part of research examines how the prices at each marketing level relate to each other and how the margin between market levels may change over time.

Data:

From the most disaggregated data (weekly level), we standardized the quality of products—specific to a variety, size of fruit, grade, and container (when available) at all marketing levels so that we can focus on price differences caused only by marketing margins.

  • To develop the retail and farm price data that include the least amount of market inputs other than raw inputs (e.g., transportation costs), we used the prices of the producing region (we designated a representative producing region in the country and collected both farm and retail prices of that region).
  • At each marketing channel, we collected the prices of the products that have the most uniform quality (or grade) at all marketing channels. Given the perishable quality of fresh fruit, our data consist of weekly prices for the period spanning from 2007 to 2011 (or 2012).

Data source and data description:

Weekly data at the retail, terminal (wholesale) and shipping point levels are obtained from Agricultural Market News, which is published by Agricultural Marketing Services, USDA. Agricultural Market News reports publish daily, weekly and seasonal price aggregates for the shipping point (or FOB), terminal (or wholesale) and retail markets. The prices at the shipping point were provided in most detail, classified by product variety, size, grade, container, and districts where products originated. Terminal prices also include this product/container information for each terminal market location. Retail prices were reported in less detail; they are classified by variety, size (depending on the fruit), and broadly defined region. Our weekly data at shipping point and terminal levels are available from 1998, but retail prices are available only from 2007.

Price patterns at the vertically coordinated markets:

The graphs below depict the weekly prices of three supplying channels for each of five fruits, for several recent years (price lines are discontinuous because prices during the off-season were not available). Graphical presentations are provided below.

The following observations stand out from the above graphs:

  • In general, retail prices show much more weekly fluctuation than FOB and terminal prices.
  • FOB and terminal prices are much more stable, with less fluctuation for apples and oranges than more perishable fruits such as peaches, table grapes and strawberries.
  • The wider fluctuation of retail prices imply that, in addition to the product purchase price paid by the retailer, there are many other factors that are critical in determining the retail price.
  • While shipping and terminal prices are closely correlated, the correlation of retail prices with shipping and terminal prices is much weaker on a weekly basis.
  • Seasonal highs and lows are clear for FOB and terminal prices, but less so for retail prices.
  • Nevertheless, the correlation of retail prices with shipping point and terminal prices seems to exist for the longer-term moving average retail prices.
  • This indicates that retailers price their products (fresh fruits) over a relatively long horizon even for a perishable product such as fresh fruit.
  • Reported strawberry prices are often higher at the terminal level than at the shipping point level, suggesting that fruit and contract characteristics may not be the same in these markets.
