This study analyzed the effect of the sensitivity of news related to onions on producers' decision-making on cultivation areas and market supply and demand. We collected onion-related article data and derived the sentiment index through sentiment analysis using neural network-based learning. We estimated the cultivation area function, including the sentiment index we made. We analyzed the impact of news sensitivity on the onion market by constructing an onion market supply and demand model. Then, we gave a sentiment index shock to the cultivation area to examine the impact on the onion market. We also explored the sensitivity analysis to emphasize the news in June, July, and August plays an important role in the supply side. To the best of our knowledge, our approach using sentiment index in the agricultural model is the first trial. Therefore, our study can introduce an approach to improve the accuracy of modeling for agriculture and apply it to the area of agricultural economics.

Plant-based meat is one of the most commercialized alternative protein foods, and its market size is increasing worldwide. Media often emphasizes such an increase is led by vegetarians' preferences. This study begins with asking whether vegetarians' roles are so crucial in the market and aims to understand their intake intention for plant-based meat. For this study, we use Decision-Tree model to identify vegetarians' characteristics and use logistic regression and ordered logistic regression to analyze the determinants of intake intention for plant-based meat. Results show the followings: First, main determinants of intake intention for plant-based meats were interest in health, food safety and the environment. Second, vegetarians' preferences for plant-based meat was not so high as media has emphasized. This study is meaningful in that it identifies determinants of intake intention for plant-based meat and suggests future strategies for consumption enhancement.

This study examined income mobility of farm household and investigated the determinants of the income mobility in Korea. For the analysis this study used Farm Household Economy Survey (2003-2020), which is surveyed by Statistics Korea, and employed transition matrix and probit specification. According to empirical results, the income mobility of farm household in Korea had been weaken for the time periods. The probability of upward and downward income mobility had been decreased; however, the probability of staying same income quintile had been increased. In particular, the tendency of remaining same income quintile became stronger around 2013. Next, we found that many farm household-related variables have positive effects on upward income mobility, which is similar to the previous studyies. However, we found stronger association between public transer income and upward income mobility of farm household in the high-income quintile rather than low-income quintile. The empirical results imply that government policy for farmhouse income should be targeted on the low-income farm household for improving income distribution and mobility.

In this study, working mechanism of the vegetable price stabilization policy is theoretically identified and the effects of this policy on farm household income is empirically assessed. Farm household income is evaluated to be increased by KRW 119.36 billion for the producers of winter radish, autumn radish, autumn cabbage and garlic, if the actual supply amount from the farmers participating in the policy is the same as the contract quantity under this policy. In addition, the income increase of non-participating farmers is estimated to be 107.3 billion won which is very high compared to 12.03 billion won for the income increase of participating farmers. The estimated overall effect is larger than the vegetable price stabilization policy cost of 106.9 billion won in 2021, which imply that the policy needs to be continuously implemented.

Consumers' perception of food safety can be influenced not only by the information but also by relevant experiences. Nevertheless, only a few studies have investigated how consumer experiences affect food safety consumption behavior. This study analyzes whether consumers' negative experience(incidents) regarding food safety impacts their probability of purchasing Good Agricultural Practices (GAP) certified agricultural products. The Consumer Behavior Survey for Food Data of the Korea Rural Economic Institute was used for empirical analysis. The results showed that consumers who experienced food safety incidents are more likely to purchase GAP agricultural products than those who did not. However, the GAP agricultural product consumption behaviors of elderly consumers and low-income consumers did not change noticeably even after they experienced food safety incidents.

The classical discrete choice model assumes that decision-makers consider all attributes in choice situations. However, decision-making often relies on some heuristic process instead of full attribute assessment. Unlike previous literature based on stated choice data, this study attempted to accommodate attribute inattention into a discrete choice model using market data. Our test reports getting better models fit in where they include both choice heuristic and full attribute preservation rules than in the conventional assumption. Accordingly, the heterogeneous decision rules need to be considered in choice modeling as an alternative to the traditional assumption. It is expected that this approach will help to derive food marketing implications for the consumer segments corresponding to each decision rule, reflecting multiple decision-making rules.

This study proposes a theoretical method for evaluating the effects of food assistance programs in terms of consumer welfare. In particular, we develope a mechanism to derive the equivalent variation to measure the welfare effects of changing the payment method of food assistance programs from discount and in-kind transfer to e-voucher. Further, in order to intuitively present the aforementioned theoretical discussion, this study attempts to visualize the changes in utility and budget constraint based on the economic theory on consumer choice. The results of the graphical analysis show that beneficiaries can achieve a higher level of utility when the benefits are paid through e-voucher system rather than through in-kind transfer. However, it is found that the sign of the welfare effect is varied across the characteristics of consumers when changing the payment method from discount to e-voucher.

Land price has increased significantly in recent years, affecting the liquidity gap between beginning farmers and existing farmers. The liquidity gap could result in widening inequalities in land size, asset gaps and loan alienation of beginning farmers. Using two 5-year farm-level panel dataset from the Korean Farm Household Economy Survey, this paper estimates the effect of increases in land price on borrowing with a developed identification strategy. Based on the estimates, this paper analyzes the extent of the liquidity gap between beginning farmers and existing farmers due to increases in land price. The results show that a 1% increase in farmland wealth is associated with farmers' borrowing increase by 1.82%. The results also indicate that a 20% increase in farmland wealth leads to a 6.6 million won in liquidity gap between beginning farmers and existing farmers.

The pandemic of COVID19 has significantly changed consumers' food consumption and waste behaviors. Specifically, the main section of households' food consumption shifted from food away-from-home to eating at home which could be connected with household food wastes. This study estimated the effect of COVID19 on the amount of household food wastes by using Consumer Behavior Survey for Food(CBSF) data. We analyzed the effect of COVID19 on household food waste emissions using the ordered logit model given the theory that food waste emissions are influenced by food prices and opportunity costs of food utilizing. We found that household food wastes increase after COVID19, and a change of the opportunity cost of food utilizing causes increase in food wastes. Based on results, we provide policy implications regarding reduction in food wastes.

We investigated the growth and convergence in Vietnamese rural income using the household survey data, VHLSS of the years, 2004 and 2018. The regional convergences in the district level income sources were estimated and tested. We found that real agricultural income, off-farm income, and the whole farm income all increased and converged, but the convergence rate in off-farm income was much higher than that in agricultural income. The convergence in income implies that an overall increase in rural income in Vietnam will contribute to reducing poverty rate. We also found that the geographic characteristics are the main determinants of agricultural income growth rates. On the other hand, ethnic minorities and people living in poverty have difficulties in developing off-farm income sources despite the convergence tendency of off-farm income.
