I just had a look at the interesting article by Anik. I have a few comments on the write-up. My experience shows potato consumption is also correlated with the ebb of vegetables with the advent of monsoon and flood. Potato is consumed more and so prices go up as other vegetables are washed out by rain. The other point is, the view of the write-up overlooks the cultural dimension of rice and potato. To suggest that the poor should take more potatoes instead of rice is like asking them to settle for less, thus increasing the food inequality. Once potato price goes up because of more consumption (and rice is exported) may be we will ask the poor to settle for something even less like banana-tree-stumps. This is the global pattern now. Look at the RMG sector.
