| dc.description.abstract | This paper attempts to analyze the impact road infrastructure may have on the level and degree of grain market integration on selected Ethiopian markets. Using wholesale price series of six markets and based on monthly data from January 1996 to December 2005, which is disaggregated in the pre and post construction periods, one of the major staple food crops of the country, white wheat is analyzed. The other two major crops, teff and maize were also considered in the descriptive analysis. A threshold autoregressive (TAR) Model in the form of Error Correction Model is used to evaluate the level of integration and speed of adjustment towards equilibrium. The findings of the paper show that there is enough evidence to conclude that the deficit areas are isolated from Addis while the surplus areas were found to be well integrated in both periods. Some of the markets under consideration are found to be inefficient as smaller deviations than the threshold level from the long term equilibrium tend to be cleared (arbitraged) away; the results also show that the markets under consideration, could be clustered in to three market groups, that is the surplus areas including Addis, in one group and the two deficit areas each in other groups independently, isolated from Addis. The findings imply that any agricultural grain marketing policy should realize and be aimed at these three segregated groups, separately. The results suggest that geographic differences and distance are important factors affecting spatial markets integration between Addis and the regional markets. The results also propose, the requirement of government intervention mechanisms, such as availability of information (access to local media and telecommunications facilities), as key factors to improve spatial market integration between the markets. Moreover, as construction of roads alone hasn’t as such improved and produced a significant impact on the level of market integration, the results indicate the need for a coordinated effort of the other market enhancing instruments; market information and institutions and put forward a system of commodity exchange as a mechanism that can incorporate these instruments. Key words: Market integration, threshold level, Monte Carlo simulations, wheat, and construction of roads. | en_US |
