The government of Optima, a small developing country which cannot affect world prices, wishes to achieve self sufficiency in food so that domestic production is enough to cover caloric needs. At present, food is imported while Coffee is exported. If self sufficiency involves producing at least X units of food at home where X is more than the current production levels. The Finance Minister proposes attaining self sufficiency by putting a tariff on imports of food and raising the tariff until the country is self sufficient. The Minister for Agriculture suggests a subsidy to the production of food. He argues that this would not hurt consumers and so is the best way for production to be raised and the least cost way of attaining self sufficiency as defined above.
