In poor countries, most governments implement policies aiming to stabilize the prices of staple foods, which often include storage and trade measures insulating their domestic market from the world market. It is of crucial importance to understand the precise motivations and efficiency of those...

This paper provides an analytical discussion of several interconnected resource allocation problems from under-pricing of electricity used by farmers for groundwater extraction. In these situations, groundwater extraction is inefficiently high even without electricity under-pricing. Moreover,...
