In this study, the most effective policy direction is proposed by comparing the simulation results on the change in farmers' crop insurance purchase rate. We set the base scenario reflecting the current level of crop insurance purchase rate under adverse selection and evaluate the effect of additional policies through Monte Carlo simulations. As a result of the analysis, the most influential policy is identified to be lowering the surcharge rate. Decreasing the surcharge rate is expected to increase the likelihood of moral hazard and adverse selection. This causes a loss of insurance company in the mid-term. On the other hand, policy that provides an additional discount of insurance premium to low-risk farms have relatively low effectiveness in the short-term. However, this policy is expected to increase the insurance purchase rate of a low-risk farm, thereby reducing a loss of insurance company. This will lower insurance premium for crop insurance in the mid-term.

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.

This study estimates the fruit demand during the holiday and non-holiday seasons, and derives the demand curves using their price elasticities. In addition, this study analyzes the changes in producer surplus by allowing hypothetical changes in supply. Estimation results indicate that the most inelastic fruit turns out to be pears, followed by apples, mandarins, and grapes. If the supply of apples, pears and mandarins decrease by 10% in holiday season, producer surplus for each fruit is expected to increase by 4.2%, 7.6% and 1.0% respectively. On the other hand, grapes show a 0.6% decrease in producer surplus when the supply decreases by 10%.

The purpose of this study is to examine the causality between the different grades of Korean beef (Hanwoo) in the same marketing channel and to identify a leading price for each marketing channel. The efficiency of the Korean beef market is evaluated through the existence of asymmetric price transmission. As a result of the analysis, asymmetric price transmission between the farm and wholesale price is found for the 1++ and 1+ grade beef. On the other hand, asymmetry in the price transmission is not found between wholesale and retail prices. These results support that downstream Hanwoo market is efficient because there is no market power in the marketing chain from the wholesale to retail markets. However, the fact that asymmetry is found between farm and wholesale prices in high grade beef implies the upstream marketing chain is inefficient.

This study focuses on the ways for stabilizing broiler-breeding farmers profits through the vertical integration. When broiler-breeders use price information of broiler and production inputs, the risk premium decrease due to the declining volatility of profit. In other words, volatility and risk premium turn out to have a positive relationship, therefore risk-aversion coefficient is estimated to have a positive relationship with risk premium. The risk premium for the scenarios that assume farmers use the least amount of information is estimated to be 7.0~30.4 won per broiler depending on the risk-aversion coefficient and the risk premium for the scenarios that posit farmers use the most information is estimated to be 3.4~15.0 won per broiler.

Domestic horse industry is mostly considered a gambling industry for the negative aspect of horse racing, which is anticipated to serve as a factor that impedes medium to long term industrial development. Thus, for the development of horse industry, support and R&D mostly emphasized on horse racing by now need to be allocated to develpte the plans for shared growth along with many other related areas. And simultaneously with that, perception change on horse industry by promotion of positive aspects of it, such as linkage with rural tourism and rehabilitation treatment is required. To achieve it, this study has develped five strategic goals and four-to-five detailed strategies for an individual target, and implemented a importance and priority assessment with the anlaytic hierarchy process (AHP). The results of the analysis show that the reinforcing of the base of horse industry is considered the most imporatant R&D plan. However, the importance and priority of some objectives and strategies differed by group categorized on characteristics.

As consumer demand for well-being livestock products increases, the regulation of government on livestock products has been tightened. In this context, as an alternative to meet both internal and external needs of the industry, livestock farming in mountain areas was proposed. However, despite the aforementioned advantages and support, livestock farming in the mountain area has not been actively pursued. In this study, simulation analysis is conducted to find out why livestock farming in mountain areas is not widely adopted. The analytical results indicate that land cost is the most important factor for livestock farmer in making the decision of adopting livestock farming in mountain areas since it requires a large land area. The best livestock species for the mountainous area is identified to be Hanwoo.

This study estimats the willingness to pay (WTP) for Korean Geobong and Shinemusket and discuss the possibility of exporting them to Thailand. According to the analysis, the average WTP for Korean Geobong before providing information is estimated to be 731.8Bhat, and after providing information is 790.6Bhat which is increased by 58.8Bhat (8.0%). The average WTP for Korean Shinemusket before providing information is estimated to be 1,019.9Bhat, and after providing information is 1,140.0Bhat which is increased by 120.1Bhat (11.8%). In the result of the changes in WTP by separating consumers from the awareness of Korean Geobong and Shinemusket, both shows greater information value in low awareness group than in high awareness group. Based on the analysis results of this study, marketing strategies that promote information on awareness or variety of Korean products are expected to increase demand of Thai consumers.

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.

While most previous studies have mainly regarded data on consumers’ buying cycle as ordinal ones, we assumed that it captures the number of times that consumers making purchases within a given period of time. In this respect, we used count data models to investigate the differences in factors influencing purchase frequency for eco-friendly labeled food between households with and without children. Main findings of the study are as follows. First, we found that the households with young children purchase eco-friendly labeled food more frequently within a given period of time. Second, we found the differences in purchasing behavior between two groups in terms of three perspectives: (1) loyalty, (2) consumption tendency (cost effectiveness versus satisfaction inclination), and (3) major purchasing items. Based on the results, we presented marketing strategies tailored to each group to expand the demand for eco-friendly food.
