COFFEE COMMODITY CHAIN
Tine S. Olsen and Brett Inder♦

ABSTRACT:
To explain the value added along the coffee commodity chain we propose and estimate a theoretical model of the coffee commodity chain. The theoretical model consists of four markets and five agents in the coffee commodity chain and predicts that prices in the coffee commodity chain move together but are also influenced by income, technology and production. A vector error correction model is used to test the theoretical predictions. In addition to the theoretical conclusions the empirical model confirms the beneficial role of the International
Coffee Agreement and the importance of the level of

Darity and Davis (2005) argue that in the study of uneven development the North-South trade and growth literature provides insights which have been neglected by the later literature of new growth theory and new trade theory. This has encouraged us to apply North-South models to the coffee value chain. The theoretical model derived in section 2 builds on Bloch and Sapsford (2000) who model primary commodities used as inputs in the production of manufacturing. Where Bloch and
Sapsford (2000) take an aggregate view of primary commodities and manufactures, we here focus on coffee and hereby take an approach similar to Boratav (2001) who examines terms of trade for individual commodities. And just like Bloch, Dockery, and Sapsford (2004) we analyse the effect of mark-up on wages and commodity prices on the final consumer prices.
Price transmission literature such as Hazell, Jaramillo, and Williamson (1990),
Mundlak and Larson (1992), Baffes and Gardner (2003), Krivonos (2004), Morisset (1998) and Weldegebriel (2004) also offer a framework to analyse prices of commodities at different

nodes of the commodity chain. This part of the literature views producer and retail prices as determined by world prices. In Bloch and Sapsford (2000) the price of manufactures, which is a good higher up in the value chain if it is
