Corn is an essential grain in the Mexican culinary, cultural and social heritage. However, the volatility in corn prices brings uncertainty to agricultural farmers and has caused an increase in imports of the grain from other countries. The purpose of this study is to use time-series models regularly applied in finance to an agricultural commodity ...
Farmers in the MENA (Middle East and North Africa) region face several interrelated challenges including natural resource depletion, low crop productivity, and food and nutrition insecurity. To address some of these challenges, governments are considering different incentives to increase crop production. However, incentives often entail trade-offs ...
Depuis le milieu des années 2000, les marchés agricoles internationaux s’illustrent par une volatilité accrue de leur prix. Cet article décrit les conditions d’institutionnalisation d’un régime de prix volatil et des marchés à terme comme réponse à cette nouvelle incertitude marchande. Il analyse le développement contemporain des contrats à terme e...

Cet outil, qui mobilise données statistiques et économiques, vise à faciliter la concertation et la recherche ...
This article analyzes literature on the history of cattle ranching and agricultural innovation adoption in Colombia to understand how livestock production systems have evolved from the 1950s until today. Departing from new scholarship that has questioned the idea that cattle ranching has been only a land-grabbing strategy dominated by few elites, t...
This analysis investigates the potential mechanism and the practical significance of the impacts of agricultural value chain development in a geographically challenging rural area of a developing country. We use data from a carefully designed primary survey administered in the hill and mountainous region in Western Nepal. Using the inverse probabil...
In this paper, we describe how both the existing degree of price correspondence and tradability are important factors explaining why and the extent to which grain price relationships adjust due to growing condition variations. For a set of maize and millet markets in Niger and Nigeria with different agro-ecological characteristics and strengths of ...
In Colombia, there are traditional food supply centers to trade agricultural products. Government institutions publish sale prices of these products in weekly reports. In order to determine the random characteristics of these price series and if there are relationships between the centers, we use a battery of six different tests to examine the weak...
Weekly series of agricultural prices usually exhibit seasonal variations and the stationarity of these variations should be taken into account to analyse price relationships. However, unit root tests at seasonal frequencies are unlikely to have good power properties. Furthermore, movements in actual price series are often not as expected when unit ...
The absence of an agricultural census in Nigeria means that samples for surveys to estimate agricultural production are obtained from a non-comprehensive, non-representative set of farms. Therefore, aggregate production data quality is questioned. The methods employed herein provide a new way to empirically evaluate the quality of agricultural prod...
