imported agricultural products will not result in equal benefit as the policy of exporting

expansion.

Among subsidy policies in agriculture sector, income guarantee with product quantity

limited is the most effective policy to increase farmers’ income; their income will increase
more than the amount of subsidy money. Whereas the subsidy to factors of production and

price guarantee policy (without product quantity limited) are the policies that only 50 – 60

percent of the subsidy money will be effectively increase farmers’ income, while the rest of
the money will be effectively used as to subsidize for the agricultural products’ consumers

including oversea consumers. However, the income guarantee policy should be implemented
for only a short term to impede the consequences on the competitiveness of Thai agricultural

products in the long term.

These policies can also be applied as policy mix, to boost the positive impact for the

society, such as increasing exporting and enhancing the effectiveness of transportation and

distribution of goods at the same time, or to reduce some negative effects of one policy by
using another policy to support, such as to increase productivity and expand exporting

simultaneously so that the demand will increase and the prices of products will not
dramatically decrease.

Lastly, the results of this study are based on the behavior structure in the model that
some of its assumptions may differ from the reality. Therefore, one should consider carefully

when applying the findings of this study.
