Cost Pass-Through in the Swedish Coffee Market
- 2017
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Cost pass-through to retail prices shows how changes in marginal costs are allocated between producers and consumers, and it is therefore closely related to market structure and competition. This paper uses Swedish data on coffee products at the barcode level to evaluate pass-through from the cost of green coffee beans, the main marginal cost, to the retail price of roasted and ground coffee. First long-run cost pass-through is estimated for each product, and then regression is used to analyse how pass-through varies across market shares, retailer-owned brands and other product characteristics. A general result is that pass-through is roughly complete for products with large market shares, while those with small market shares have low pass-through rates. There is no evidence that retailer-owned brands have higher pass-through than brand-name products with similar market shares, which would be the case if retailer-owned brands avoided double marginalization through vertical integration. Thus, although there is not perfect competition in the Swedish coffee market, a large part of it appears to be highly competitive.

Tidskriftsartikel (refereegranskat)abstract
- Lao PDR has extensive export controls on its staple food, glutinous rice, which keep domestic prices low relative to international prices. Using price, harvest, and export data this paper analyses how glutinous rice prices in Laos PDR are related to those in its trading partners, Thailand and Vietnam. We find that rice prices in Lao PDR are more likely to rise following a good harvest year than a bad or a normal year. This is consistent with export controls being relaxed after good harvests, leading to an increase in exports early in the season and rising prices later as stocks are depleted. There is thus a case for removal of trade restrictions since they give rise to price spikes while keeping the long-term price of glutinous rice low, and thereby hinder increases in income from agriculture. However, since high rice prices are likely to affect the poor negatively in the short to medium term, a combination of an export tax and cash transfers is recommended during the transition period. Although this is a case study of Lao PDR, the findings may equally apply to other developing countries that export their staple food.
