This paper seeks to explain the incomplete transmission of coffee bean pric
es to consumer prices. We adopt and estimate an aggregate model of oligopol
istic interaction. We obtain demand and cost parameter estimates that are c
onsistent with conventional wisdom in the industry. Conduct is estimated to
be relatively competitive. Our results imply that the relatively large sha
re of costs other than bean costs accounts for the greater part of the inco
mplete price transmission. The remaining part is due to mark-up absorption,
but is less important as oligopolistic interdependence is relatively compe
titive.
