Price Transmission Asymmetries and Nonlinearities in the International Coffee Supply Chain AgEcon
Lee, Jun; Gomez, Miguel I..
We examine two distinct and important dimensions (e.g. symmetry vs. asymmetry and linearity vs. nonlinearity) of price transmission from international to retail coffee prices in France, Germany and the United States. We show that ignoring these two features of the price transmission process may lead to misleading impact assessments resulting from the elimination of International Coffee Agreement (ICA) in 1990. Our results confirm the presence of threshold effects in both periods (ICA and post ICA) in all three countries. Our estimates show that, in the long-run, the speed of adjustment toward equilibrium becomes faster during the post-ICA period in France and Germany. Our results suggest that, for these two countries, changes in international prices did...

An Error Corrected Almost Ideal Demand System for Major Cereals in Kenya AgEcon
Nzuma, Jonathan M.; Sarker, Rakhal.
Despite significant progress in theory and empirical methods, the analysis of food consumption patterns in developing countries, particularly those in Sub Saharan Africa has received very limited attention. An attempt is made in this article to estimate an Error Corrected Almost Ideal Demand System for four major cereals consumed in Kenya employing annual data from 1963 to 2005. The model performs well both on theoretical and empirical grounds. All own-price elasticities are negative and statistically significant and all cereals are necessities both in the short-run and in the long-run in Kenya.
