Adopting the Ricardian approach, this study investigates the economic effects of climate changes such as average temperature and rainfalls on Korean livestock farm revenue. The explanatory variables of empirical model were selected based on the previous literature. The pseudo-panel analysis is employed to resolve the imperfectness of the panel data. The results indicate that the control variables such as farming experience, household size, employment, ownership of heavy machinery, technology use, full-time farming and male owner affect the livestock farm revenue positively, and the age does negatively. The impact of summer average temperature on farm revenue was significant and negative, while that of winter was significant and positive. The marginal change of the summer temperature decrease farm revenue per head by 2.48%. This paper suggests that the livestock farm’s revenue responds sensitively to changes in summer and winter average temperature, and so we need to establish the long-term countermeasures against rapid climate change.

Food waste has increasingly gained global attention and households are identified as the largest source of food waste along the entire food supply chain. Thus, it is necessary to have a clear understanding of the factors influencing food waste-related consumption behaviours and consumer perceptions in household levels. This study seeks to determine factors causing consumer-related food waste in households. Based on a nationwide survey of 3,335 consumers, this article examined the associations of households’ attributes, attitudes, and behaviours with self-reported household food waste. Using structural equation techniques, household food waste is modeled as a function of the food consumption behaviour, consumers’ perceptions of dietary habits and volume-based waste systems. Results show that making shopping list, environmental attitude, perception for less food waste behavior negatively affect household food waste, while household size, income, food preparation, check expiration date are associated with more household food waste.

This study focuses on the effectiveness of the support program for slaughterhouses and meat processing plants using the results of a survey conducted on slaughterhouses and meat processors to evaluate the modernization of the facilities and funding projects for running these operations. For the data obtained through the survey, a widely used propensity score matching technique was applied to identify the impact of government policy measures or system implementation. According to the result of the analysis, it was found that the average number and maximum number of hogs slaughtered per day were significantly higher for the companies participating in support projects than those that did not. In addition, it was revealed that the slaughterhouses that participated in support projects had more cattle and hogs to be slaughtered on average per day and the maximum number of slaughtered livestock per day compared to those that did not. Compared to slaughterhouses that did not participate in support projects, 1,436 more hogs were slaughtered per day on average, and the maximum number of hogs slaughtered per day was higher by 765~815 heads. It was calculated that slaughterhouses that participated in support projects could process an average of 60 more beeves per day compared to those that did not. In the case of hogs, it was found that the maximum slaughter quantity per day increased by 765 heads, and the average number of slaughtered heads per day increased by 1,374 heads.

Given increasing competition in beef meat market by growing meat import, decisions have to be made to allocate limited resources for developing beef cattle industry. To secure effectiveness of government policies under the limit of resources availability, this study identifies and weights twelve strategies or policy options that influence beef cattle industry and determines priorities among strategies by incorporating best-worst scaling technique into an expert surveys. Results reveal that on average experts displayed extreme preference for enhancing marketing and consumption of beef cattle meat and were less concerned about other aspects of production strategies. Expansion of distribution network, aggressive marketing strategies, and beef farmers education for improving meat quality were among the most important to beef cattle industry, whereas the veal and young cattle market pioneering, and enhancing traceability and country of origin labeling on food service menus were among the least important. This analysis provides estimates of best-worst scaling that help explain the current status of beef cattle industry, and the results have implications for the policy proposals, particularly in light of the experts.

This paper investigates the relationship empirically between land consolidation and agricultural productivity in South Korea. Drawing upon panel data set which consists of rice production and area of land consolidation in eight regions from 1970 to 1990, we estimate the effect of land consolidation fueled by Saemaul Undong on agricultural productivity in terms of rice production. Panel model results show that land consolidation indeed leads to higher agricultural productivity.

다양한 국가들과의 FTA 체결에 따른 농산물시장의 개방폭은 확대되고 국제유가와 곡물가격에 등락에 따라 우리나라의 물가는 직접적으로 영향을 받는 등 우리나라 농업을 둘러싼 대외적인 환경은 급속히 변화하고 있다. 이와 함께 대내적으로도 우리나라 농업은 고령화와 영세화, 도시에 비해 상대적으로 열악한 농촌지역 삶의 질과 의료, 복지, 교육 등 사회안정망의 취약 문제에 직면하고 있다. 본 연구는 통계청의 2015년 농업총조사자료를 기초로 우리나라 각 도별 농업경쟁력을 비교하였다. 도별 농업경쟁력 비교를 위해서 생산요소, 생산성, 농업 및 농촌관련 지방재정투입, 지역집중 등의 농업역량과 관련된 내용들을 지수로 선정하여 계측하였다. 이러한 네 가지 지수를 종합적으로 고려하여 종합적으로 계산된 각 도별 농업경쟁력 지수는 경북이 가장 높고 전남, 충남 순으로 나타났으며 제주지역이 가장 낮은 것으로 분석되었다. The issue is of importance in agricultural sector where competitiveness conditions differ across regions and might increase under the action of the recent policy, economics and social changes, induced primarily by the Free Trade Agreements, the hight domestic cost, and the new public priorities. The agricultural competitiveness of each provinces of Korea was compared by using the regional agri-competitiveness index approach that is made up inputs, productivity, finance input, and location quotient. Results indicates that Gyeongbuk has the highest competitive advantage in agriculture and Jeju has the lowest agricultural competitiveness.

This paper determines Hanwoo farmers’ preferences for government support programs, by implementing the best-worst scaling approach. Farmers are segmented based on the relative importance, which is perceived by the farmers, of support programs. Among thirteen support programs for Hanwoo farmers, four different programs, namely, feed cost sharing program, checkoff program, slaughterhouses restructuring, and animal disease control were of paramount importance to Hanwoo farmers. However, significant variations are found among farmers in the relative importance of support programs, dependent on farm scales.

In Korea each year an estimated 0.9 million people ride horses. As the number of horse riders continues to increase, there has been an increase in the number of riding clubs. This study seeks to determine the potential for success of riding clubs. Based on data from on site survey, which is designed to be representative of Korean horse riding clubs, this paper focuses on business diagnostics and explores the factors affecting the business performance for improving competitiveness. Results show that more than 70% of riding clubs recorded the excess profits in 2019, however, more than 40% of their sales relied on government assistance programs. Our ordinary least squares estimates found worker types, the number of certified coaches, membership types, regions had a significant effect on business performance. Taken together, the results suggest more detailed data and methodological work is needed on how to robustly capture management efficiency and derive improvement measures to riding clubs.

When consumers are uncertain about the quality of a good, government programmes and policies can serve as signals to them. This paper analyzes the relationship between government labeling policy and consumers’ beliefs about genetically modified food. Survey data are used to estimate an structural econometric model where beliefs about the safety of genetically modified food, beliefs about government labeling policy, and willingness to consume genetically modified food are endogenously determined. Results show that consumers who believe the government has a labeling policy for genetically modified food are more likely to believe genetically modified food is safe
