Book (stand-alone)Household level impacts of increasing food prices in Cambodia 2010
Also available in:
No results found.There has been widespread concern regarding the surge in staple prices over the last few years and developments have been widely recognized, although to a varying degree, as one of the recent price surge and increased price volatility. Within the Asian context, food security conditions are mostly related to rice production and the price of rice. The analysis presented in this paper sheds light on the impacts of the increase in the prices of key food staples on different household groups and identifies the vulnerable segments of the population. The analysis shows that generally Cambodia gains from an increase in the price of rice although particular segments of the poor stand to lose. The analysis concludes that from a food security perspective, the price of rice should be monitored closely while considering the identified vulnerable household groups. -
Book (stand-alone)Exploring the impact of alternative population projections on prices, growth and poverty developments 2018
Also available in:
No results found.This study aims at exploring the implications for future economic growth and poverty of different agricultural price trajectories through scenario analysis. Agricultural prices are not a given but the end result of underlying changes in demand and supply. Acknowledging that the future is uncertain we assess the implications of contrasting developments in population, a key driver of agricultural prices, through its impact on demand. Using MAGNET, a global computable general equilibrium (CGE) model we develop three scenarios. The reference or baseline scenario is built upon the “Middle of the road” Shared Socioeconomic Pathway (SSP2), projecting from 2010 to 2030 with no major divergence from historical patterns. We then construct alternative high and low price scenarios by varying assumptions on population growth. The aim is not to predict the future but to systematically think through how different paths of a key driver changes how the world may look. Any model covering the entire world economy uses a large number of assumptions with varying levels of empirical support. We therefore also highlight key assumptions which need more empirical scrutiny to improve our understanding of the likely direction of future development -
DocumentAnalyzing the impact of food price increases: assumptions about marketing margins can be crucial 2009
Also available in:
No results found.This paper shows the importance of explicitly considering marketing margins in analyses of the impact of price changes on the welfare of different segments of the population. Failure to acknowledge the implicit marketing assumptions embedded in an analysis that assumes equal percentage changes for both farm and consumer prices leads to a bias towards finding negative impacts of higher food prices. In addition, the bias is not necessarily uniform across income quintiles; thus, failure to explicit ly consider marketing margins could lead one to conclude that the poor are hurt relatively more than the rich by a price increase when in fact the opposite is true, or vice-versa. We provide rules of thumb and simple techniques that may help to ascertain, in many circumstances, the percentage change in consumer prices that is appropriate for a given percentage change in farm prices.
