| This paper discusses a modeling approach that extends and improves the standard parity bounds model (PBM) of spatial market efficiency by analyzing the dynamic effects of marketing policy changes. The model facilitates an improved understanding of the patterns of adjustment in grain marketing efficiency in response to policy changes in two main ways. First, it identifies whether there are statistically significant structural changes in trading regime probabilities as a result of a given marketing policy change. Second, it determines the time path of the response of spatial grain market efficiency to marketing policy changes, thus addressing the issue of how long will it take before the full effect of marketing policy change is realized on spatial grain... |

| In the context of on-going market reform in developing countries, there is a need for an improvement in the existing methods of spatial market efficiency analysis in order to better inform the debate toward designing and implementing new grain marketing policies, institutions, and infrastructure that facilitate the emergence of a well developed and competitive grain marketing system. The standard parity bounds model (PBM), while it overcomes many weaknesses of the conventional methods of spatial market efficiency analysis, it does not allow for the test of structural changes in spatial market efficiency as a result of policy changes. In this paper, building on the standard PBM, we develop an extended parity bounds model (EPBM). The EPBM is a stochastic... |

| The major objective of this paper is to identify determinants of market prices for cattle, sheep and goat in the export market value chain starting from pastoral markets to export abattoirs and live animal exporters. The study is based on the information generated through a formal survey conducted in the major pastoral livestock markets of Ethiopia with 128 collectors, small and big traders, feedlot operators, live animal and meat exporters. Hedonic price formation model was used to analyze the survey data. This study identified certain occasions such as Christian fasting, Muslim fasting, holidays and other times; time of a situation whether that specific month falls during ban time or not and season described as wet or dry season as important determinants... |

| One objective of this paper is to examine the trends and changes in crop production before and after the implementation of the partial market liberalization policies starting in the early 1990s. Another objective of the paper is to assess agricultural production performance and its implications for household food security. These issues are examined on the basis of the Crop Forecast Survey (CFS) data, Post Harvest Survey (PHS) data, Central Statistical Office (CSO) price data, data from the Agricultural Market Information Centre (AMIC) at the Ministry of Agriculture, Food and Fisheries (MAFF), and other data. |
