| 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 und die Determinanten dieser Reaktion werden für 85 Marktpaare von Januar 2000 bis Oktober 2008 untersucht. Zu diesem Zweck wird ein semi-parametrisches partiell-lineares Regressionsmodell genutzt, das imstande ist, den Einfluß der Marktentfernung, der sich als nichtlinear herausstellt, adäquat zu modellieren. Die Ergebnisse der Untersuchung sind kohärent mit der ökonomischen Theorie und von politischem Interesse. Ein Grenzeffekt wird identifiziert, der in dem Sinne... |

| This study uses a rich dataset of 85 market pairs between January 2000 and October 2008 for Kenya, Tanzanian and Uganda, the three largest member countries of the East Africa Community, to analyze the factors determining national and cross-national maize price transmission. Although the three countries are members of the community’s customs union and they each claim to pursue maize trade without borders, their agricultural trade policies still differ, thus affecting prices and trade flows to different extents. This analysis extends the existing border effects literature in three ways. First, it assesses the magnitude of price transmission, instead of analyzing trade flows or price variability. Second, distance is shown to have a significant impact on price... |

| Since the seminal work of Adam Smith, markets have been considered an efficient tool for co-ordinating the behaviour of economic agents. The basic characteristic of a market economy is that the complex system of interaction among individuals is not centrally coordinated. Under the assumption of profit and utility maximisation (and a whole set of assumptions about the institutional framework), relative prices and their change over time provide the signals that guide, like an invisible hand, the allocation of resources, i.e., the structure of production and the intensity of input use in the various production processes. They do this by co-ordinating the activities of economic agents, i.e., of resource owners, producers, intermediaries, traders, and... |
