Government interventions have distorted the major grain markets in Cos
ta Rica since the 1940s. While Initially intended to achieve price sta

, and ready access to world markets. This paper shows that significant
national economic savings could be achieved if the grain markets were
liberalized. Moreover, since current policies are shown to transfer i
ncome from consumers and poor farmers to large-scale rice farmers, mar
ket liberalization would in most cases assist rather than hurt the poo
