Book (stand-alone)Price transmission in selected agricultural markets 2004
Also available in:
No results found.The paper is aimed at providing evidence on price transmission in a number of agricultural markets, both per se and in support of analytical efforts in the area of agricultural trade policy analysis. Work is based on a price database collected from various sources in sixteen countries Argentina, Brazil, Chile, Costa Rica, Egypt, Ethiopia, Ghana, India, Indonesia, Mexico, Pakistan, Senegal, Thailand, Turkey, Uganda, and Uruguay primarily for basic food commodities. Both spatial and vertical p rice relations are considered, as the database includes prices at the producer, wholesale and retail levels. These are supplemented with information from FAOSTAT. Data are analyzed with an econometric framework based on the estimation of Autoregressive Distributed Lag models, and of the corresponding Error Correction specification. Tests for Granger causality and for asymmetric transmission are also performed. Results indicate that the African markets included in the sample are characterized by more incomplete transmission compared to Latin American and Asian markets. -

ArticleCombining market structure and econometric methods for price transmission analysis
Food Security, August 2019, Volume 11, Issue 4, pp 941–951
2019Also available in:
No results found.Much attention has been devoted in the literature to the analysis of price transmission along food supply chains. Price transmission analysis has traditionally focused on applying econometric methods to assess price dynamics and interrelationships. However, the exclusive application of econometric methods without considering the market’s institutional context has limited potential to support evidence-based policy-making. In recent years, studies have thus attempted to combine the use of quantitative and qualitative methods to better understand the level of performance of food value chains. This study contributes to broadening these empirical toolkits by suggesting a structured analytical framework that benefits from the simultaneous application of econometric and market-structure methods in price transmission analysis. To illustrate the application of the framework, we analyze the milk market of Panama.
