Urban bias in price risk: The geography of food price distributions in low‐income economies
研究基础设施薄弱经济体中农村与城市食品价格风险的差异，发现城市偏向的价格风险对季节性买卖粮食的农民福利有不利影响，基于马达加斯加大米价格数据验证。
The geography of agricultural marketing has important implications for the stochastic distribution of agricultural commodity prices. This article proposes that objective food price risk differs between rural and urban areas of infrastructure‐poor economies characterised by spatially concentrated patterns of foodgrains storage. This difference implies an urban bias having adverse welfare effects for peasants who seasonally switch between net food seller and net food buyer positions. Empirical analysis of rice price data from Madagascar suggests that price variability and skewness indeed differ between rural and urban areas in ways that adversely influence the relative welfare of rural peasants.
