Higher Fuel And Food Prices Economic Impacts And Responses For Mozambique

Since 2006, global food prices have fluctuated greatly around an increasing trend and price spikes were observed for key food commodities such as rice, wheat, and maize.

In the wake of the global food crisis of 2007–08 and additional price spikes since then, greater attention has been given to the welfare impact of food price increases in developing countries. The standard approach in this type of analysis, proposed by Deaton (1989), is based on income and expenditure data from household surveys. Given the widespread use of this method, it is important to revisit the assumptions behind it and examine the sensitivity of results to those assumptions. In this paper, we explore the distributional impact of higher maize, rice, and food prices in Ghana and analyze the robustness of those results to changes in several key assumptions. The results suggest that higher maize and rice prices have a relatively modest short-term impact on national poverty but significant effects on specific groups of households. As expected, urban households lose from higher grain prices, but a surprisingly large share of rural households also lose because they are net buyers. The results also suggest that the current policy of protecting domestic rice producers with an import tax does not contribute to national poverty reduction, in spite of the fact that rice growers tend to be poor. If we relax the assumption that households do not respond to the higher prices, the effects are more positive or less negative, but only modestly so. On the other hand, if we relax the assumption that producer and consumer prices rise by the same proportion, and instead assume a constant marketing margin, the results change substantially. Because producer prices now rise by a larger proportion than consumer prices, the impact of higher prices is much more positive. These findings highlight the need for more research on the effect of price spikes on marketing margins.

"Previous studies implicitly assume uniform price-effects across regions or provinces within countries. They also do not address the issue of integration between the world food market and local markets. Instead, they assume a complete transmission of changes in world food prices to local food prices. In this paper, we first establish evidence of regional price heterogeneity across Ethiopia. We also applied the Johansen test for market integration over 95 local maize markets and found that none of the Ethiopian regional markets for maize is integrated to the world market. However, there is significant short-term price effects between the world maize market and some Ethiopian regional markets. Using the Almost Ideal Demand System, we estimate loss in household consumption and calorie intake as induced by food price increases. The results suggest a great deal of heterogeneity across regions as well as between rural and urban areas. Studies that fail to account for the characteristics of household demand across locations are more likely to induce misleading policy recommendations."--Authors' abstract.

In developing countries, all too often policies formulated in response to high food prices are inspired by ideology instead of evidence-based policy research. We look at the immediate effects of these shocks faced by households in Uganda on their poverty and well-being. In addition, we look at the economywide impact in the long run when all markets have settled at a new equilibrium. We find that in the short run, poverty has increased substantially. However, in the longer run, we find welfare levels of rural farm households in particular to rise sharply, primarily as a result of increased returns to farm labor and agricultural land coupled with improved market prices for output sold. These results call for policies that aim to protect the most vulnerable against high food prices and extreme volatility in the short run, without eliminating the incentives of steadily rising commodity prices for longer-run structural agricultural development.

This book aspires to be a comprehensive summary of current biofuels issues and thereby contribute to the understanding of this important topic. Readers will find themes including biofuels development efforts, their implications for the food industry, current and future biofuels crops, the successful Brazilian ethanol program, insights of the first, second, third and fourth biofuel generations, advanced biofuel production techniques, related waste treatment, emissions and environmental impacts, water consumption, produced allergens and toxins. Additionally, the biofuel policy discussion is expected to be continuing in the foreseeable future and the reading of the biofuels features dealt with in this book, are recommended for anyone interested in understanding this diverse and developing theme.
