This paper estimated how demographic characteristics, food selection preferences, daily physical activities, and food purchasing patterns of consumers affect the consumer choice to buy coffee and tea by analyzing the Consumer Panel data in 2014 using Multinomial logit model. The results are summarized as follows. First, factors such as age, income, employment status, and educational level were found to be statistically significant upon the impact analysis of consumers’ demographic characteristics. Second, the study showed that the first group of consumers drinking less coffee and tea had the highest interest in health, followed by the third group drinking less coffee and more tea, the second group more coffee and less tea, and the fourth group more coffee and tea. In addition, it was also found that the fourth group’s pattern to purchase more coffee and tea could be explained by consumers’ food consumption patterns.

This paper predicts the onion’s cultivation areas, yields per unit area, and wholesale prices during ship dates by using wholesale price data from the Korea Agro-Fisheries & Food Trade Corporation, the production data from the Statistics Korea, and the weather data from the Korea Meteorological Administration with an ARDL model. By analyzing the data of wholesale price, rural household income and rural total earnings, onion cultivation areas in 2015 are estimated to be 21,035, 17,774 and 20,557(ha). In addition, onion yields per unit area of South Jeolla Province, North Gyeongsang Province, South Gyeongsang Province, Jeju Island, and the whole country in 2015 are estimated to be 5,980, 6,493, 6,543, 6,614, 6,139 (kg/10a) respectively. By using onion production’s predictive value found from onion’s cultivation areas and yields per unit area in 2015, the onion’s wholesale prices in June are estimated to be 780 won, 1,100 won, and 820 won for each model. Predicted monthly price after the onion’s ship dates is analyzed to exceed 1,000 won after August.

남국현(Kuk Hyun Nam),최영찬(Young Chan Choe) 한국농촌지도학회 2016 농촌지도와 개발 Vol.23 No.4

This paper estimated the demand function of the cuts of Korean beef and imported beef by using the consumer panel and retail price data from the Korean Agro-Fisheries & Food Trade Corporation, and the weather data from the Korea Meteorological Administration with an log-log model and AIDS model. The results show that the preference for cuts of beef used for cooked soup, steamed dish, Changjorim are more elastic than cuts used for roasting when there is a change in price and income in the estimation of demand function of Korean beef. On the other hand, consumers respond sensitively with the demand of roasting part compared to steamed dish, Changjorim, soup when there is change in price and income in the estimation of demand function of imported beef. The results indicate that there is substitutional relationship betw een Korean beef and imported beef, because Korean beef cuts used for roasting can substitute for imported roasting part and the same relationship applies to steamed dish, soup, Changjorim. In addition, family number, family member, husband job, purchasing place, means of transportation, purchasing time, weather are statistically significant.

여성의 결혼과 출산의 결정요인 분석

남국현 ( Kuk Hyun Nam ),김대일 ( Dae Il Kim ) 한국여성경제학회 2016 여성경제연구 Vol.13 No.2

저출산은 부양비율 증가, 성장동력 약화 등 경제 효율성 뿐 아니라 소득 불평등에도 부정적 영향을 미친다(김대일 외, 2014; 김대일, 2005). 본 연구는 여성의 결혼, 첫째 출산 및 둘째 출산 해저드(hazard) 추정을 통해 저출산에 대한 시사점을 얻고자 한다. 각 해저드를 학력, 취업 및 출생년도의 함수로 추정하여, 최근세대의 고학력화와 취업으로 인한 효과와 그 이외의 사회경제적 환경변화에 의해 유발된 효과를 비교한다. 분석에 의하면 최근세대의 고학력화와 취업확대는 만혼 및 저출산 추세의 3∼20%를 설명하는 것으로 나타났다. 결과적으로 여성 개인의 고학력화와 취업도 만혼과 저출산 추세의 주요 원인이지만, 모든 여성에게 공통적으로 영향을 미치는 사회경제적 환경 요인이 더 큰 역할을 하고 있다고 판단된다. Low fertility not only reduces economic efficiency but also impairs economic equity. This paper estimates women`s exit hazard into marriage, first and second births to obtain the implication on declining fertility. These hazards are modeled as functions of education, employment and birth cohort, where the latter is designed to pick up the effects of social and economic environmental factors. The results suggest that higher education and greater employment of recent women account for a non-trivial portion of the between-cohort differences of the hazards, but a much larger part of the differences remains to be accounted for by social environmental factors.

남녀 근로자의 숙련향상에 관한 연구

본 연구는 남성과 여성의 숙련수준의 증가를 개인적 특성과 공식훈련, 비공식학습, 품질관리제도, 업무특성, 조직문화 등의 변수로 추정하여 비교분석하였다. 분석에 의하면 남성은 근속년수, 전문대졸, 선후배 및 동료 간 상호작용 학습, 직무관련 자격증, 제안제도, 조직문화 등의 요인이 숙련향상에 더 크게 영향을 주는 것으로 나타났다. 반면에 여성은 근속년수, OJT, 업무특성, 조직문화, 성비 등의 요인이 숙련향상에 더 큰 영향을 주었다. This study estimates the skill level of men and women as variables such as personal characteristics, formal training, informal learning, quality control system, business characteristics and organizational cultures. According to the analysis result, men have a great effect on skill improvement in the factors such as tenure, college graduation, mutual learning among workers, qualification, suggestion system and organizational cultures. On the other hand, women have a great impact on skill improvement in the factors such as tenure, OJT, business characteristics, organizational cultures, and sex ratio.

남국현(Kuk-Hyun Nam),최영찬(Young-Chan Choe) 한국농촌지도학회 2017 농촌지도와 개발 Vol.24 No.1

This paper analyses the interrelationship among wholesale price, trading volumes, import volumes and demand for three agricultural products (cabbage, onions, and garlic) by using the consumer panel and the data from the Korea Rural Economic Institute and the Korea Customs Service with a VAR model. The results are summarized as below. (1) The prices of three agricultural products decrease when trading volumes increase while the price of cabbage and onions decreases when import volumes increase. But the prices of three agricultural products have little effects on trading volumes. (2) The demand of three agricultural products increases when trading volumes increase while the demand of cabbage and onions increases when import volumes increase. (3) when demand of garlic and cabbage increases by 10%, their price increases by 2.5% and 1.3% respectively. And the demand of garlic has positive effects on import volumes of garlic.

남국현(Nam Kuk Hyun),최영찬(Choe Young Chan) 한국농식품정책학회 2015 농업경영정책연구 Vol.42 No.4

Using a consumer panel, this paper analyzed the effect of income change on exenditure of each food item after controlling demographic factors such as age, educational attain ment, employment status, family number. The results show that when income grows by one million won, per capita consumption of fruit, eating-out expenses, processed food, meat increases 4,900 won, 4,500 won, 1,600 won and 1,300 won respectively in the cross-section SUR model. In the panel fixed effect SUR model, when income grows by one million won, per capita consumption of eating-out expenses, meat, fruit, fishery products increases 4,700 won, 800 won, 400 won and 200 won respectively. Above all, the factors such as age, educational attainment, family number, job status, the number of people eating, cohabitation with parents or middle school children, preference for country of origin, price preference are statistically significant according to food expenditure.
