Spatial market equilibrium theory views trade flows as the driving force behind market integration. We assess the price linkages between five major tomato markets in Ghana to ascertain whether spatial price transmission depends solely on direct trade between markets, or whether other forces...

Diese Arbeit analysiert Faktoren, die Einfluß auf das Ausmaß der inländischen und grenz-übergreifenden Integration der Maismärkte Kenias, Tansanias und Ugandas ausüben. Die Stärke der Reaktion der Preise auf Abweichungen von ihren Langzeitgleichgewichtswerten als Maß der Marktintegration...

It is reasonable to expect that price transmission for perishable products will display seasonal variation, especially in low-income country settings. To date, however, few studies have explicitly tested for seasonal variation in price transmission. We apply a vector error correction model with...

This analysis employs cointegration methods and semiparametric regression in order to assess the integration of maize markets and the factors determining national and cross-national transmission of price signals in Sub-Saharan Africa. We use a rich dataset of 16 series of wholesale maize prices...

Maize is a major staple food in Sub-Saharan Africa. Monthly maize prices in Tanzania are analyzed since the country is an important maize producer and exporter in East Africa. We analyze price transmission between the five most important urban regions of Tanzania between 2000 and 2008 which...

We compare two regime-dependent econometric models for price transmission analysis, namely the threshold vector error correction model and Markov-switching vector error correction model. We first provide a detailed characterization of each of the models which is followed by a comprehensive...

Ethical aspects of food products have become increasingly important for Western European consumers. One example of such ethical consumption attributes are “peace products”, commodities produced in peaceful economic cooperation between members of conflicting parties in areas of political...
