| 1. Compared to the general price of goods and services as measured by the consumer price index, the prices of retail roller and breakfast maize meal have declined by between 34 and 51% in the major urban markets of Zambia between 1994 and 2010. 2. Inflation-adjusted wholesale maize grain prices have also declined over this period but by a smaller amount. 3. Inflation-adjusted marketing margins between the wholesale price of maize grain and the retail prices of roller and breakfast meal have declined from 41% to 64% since the early 1990s when the market liberalization process began. Since the early 1990s, there has been substantial new investment in commercial maize milling as well as by the informal hammer milling industry. Enhanced competition at this... |

| This study analyzes the interrelationship and volatility between grain and oil prices. Specifically, the objective of this study is to investigate the volatility transmission mechanism of grain prices with oil prices, under the assumption that an increase in crude oil prices not only affects corn and soybean prices but also other grain commodity prices such as wheat and rice. The results presented in this paper suggest several conclusions. First, there is a short-run relationship between the grain market and oil prices, which implies that recent co-movements of oil and grain prices are just a temporary phenomenon. Second, grain prices, except for rice, are affected by oil prices to some degree. Finally, the volatilities of oil prices influence the... |

| Previous studies on post-reform market performance of Chinese grain markets have produced mixed results. This paper employs province-level price data to determine if China's food market liberalization policies in the 1990s resulted in interregional rice market integration. Furthermore, this study extends the literature on spatial market integration by augmenting multivariate cointegration modeling techniques with directed acyclic models (DAGs), a recently developed statistical method for analyzing contemporaneous causal relationships. While the empirical results confirm the existence of strong market linkages subsequent to the reforms of the early 19902, the linkages became less as the Chinese government reversed several reform policies in the mid-1990s.... |
