The price fluctuation of vegetables is generally greater than other agricultural products and it constrains consumers' planned consumption and farmers' stable income. Therefore, it is necessary to identify the factors that affect vegetable price fluctuations and formulate effective policies to stabilize prices. In order to examine the factors affecting the fluctuation of vegetable prices, this paper used a structural model constructed by demand, supply, import and export functions to decompose price variance. We select cabbage, radish, dried red pepper, garlic and onion as research objects. The results indicate that production has a relatively large impact on price fluctuations while demand, imports and exports play small roles except for dried red pepper and onion. Our results provide policy implications for formulating vegetable price stabilization strategies.

This study estimates the producer’s willingness to accept (WTA) and consumer’s willingness to pay (WTP) for GAP-certified agricultural products. We apply contingent valuation method (CVM) with producer and consumer survey data. The results suggest that the producer’s willingness to accept is turned out to be the lowest for fruits followed by grains and vegetables. On the other hand, the consumer’s willingness to pay turns out to be relatively higher in grains and fruits than fruit-vegetables and vegetables. Accordingly, the difference between WTP and WTA is the largest in fruits and the smallest in vegetables. The order of this difference is exactly the same as the GAP certification rate for each category of agricultural product. Therefore, in order to increase the rate of GAP certification, the government needs to improve consumers’ awareness and reliability regarding GAP certification. Concurrently, the production side support plan should be implemented.

In this study, the Gini coefficient is estimated and decomposed within as well as between the forest industries according to income components. Analytical results indicate that the average Gini coefficient for the entire sample from 2009 to 2018 is 0.478 which can be interpreted that a high level of inequality in the forestry household income exists. Forestry investment subsidies are proven to play a vital role in alleviating income inequality for forestry households. This study suggests that government needs to increase the public forestry subsidies in order to mitigate the high level of income inequality.
