The standards for heavy metal levels in crustaceans are 0.5 mg/kg and 1.0 mg/kg or lower for lead and cadmium, respectively. Further, the contamination levels of arsenic, mercury, methyl mercury, and tin are being continuously investigated, considering their current exposure levels. Shrimps are potentially exposed to heavy metals because they inhabit areas with abundant organic matter, such as sandy or muddy shores, places with a lot of seaweed, and estuaries. This study measured the monetary value of reducing consumer anxiety and increasing consumer confidence if the government prohibits the sale of shrimp species that exceed the threshold for specific heavy metals and of the top shrimp species for which no threshold for heavy metals is specified. We derived consumer willingness-to-pay (WTP). Combining the estimated WTP with the number of households in the country, the total value of benefits was estimated to be 363.9 billion won. The results of this study will provide an important empirical finding, showing to what extent specific policies regarding heavy metals in seafood can alleviate consumer anxiety and provide psychological reassurance.

위해물질의 관리 및 규제는 소비자의 효용 증대와 질병비용 부담 감소뿐만 아니라 정부의 질병비용을 줄이는 효과가 있다. 따라서 해당 위해물질의 사회·경제적 질병비용에 대한 예측은 관련 식품 및 보건 정책에 필수적이라 할 수 있다. 이에 본 연구에서는 식품을 통한 납, 카드뮴, 비소 섭취에 따른 질병과 관련된 사회·경제적 비용을 분석하였다. 이를 위해 이 세 가지 중금속과 관련된 질병들의 목록을 도출하고, 중금속 평균혈중 농도와 질병들의 연관성을 추정하였다. 그리고 질병비용추정법을 이용하여 선별된 각 질병들이 야기하는 직·간접 질병비용을 도출하고, 세 가지 중금속의 혈중 평균 농도가 야기하는 총 질병비용을 도출하였다. 연구 결과 납의 경우 만성질환 중 4가지, 카드뮴은 6가지 그리고 비소는 5가지 질병의 유병률에 유의한 영향을 미치는 것으로 나타났고, 이러한 질병들이 야기하는 총 질병비용은 약 23조 7천억원 정도로 추정되었다. 또한 우리나라 국민들의 납, 카드뮴, 비소 평균 혈중 농도가 야기하는 총 질병비용은 카드뮴이 346.8억원, 비소 341.9억원, 납 165.0억원으로 나타났다. 이 결과는 중금속으로 인한 질병비용에 대한 보다 정밀화된 정보를 제공하고, 더 나아가 안전하고 건강한 식품을 위한 정책 효과를 가늠하는데 활용될 수 있을 것으로 여겨진다. This study attempts to estimate socio-economic costs of illness due to heavy metals, in particular, lead, cadmium, and arsenic, which have drawn special attention recently in food hazard management. For our analysis, we listed illnesses related to the three heavy metals and examined, using a logistic regression, their association with the blood concentration of each of these heavy metals. Next, by using COI (cost-of-illness) method, socio-economic costs caused by illnesses which were found to be related to one of the three heavy metals were calculated and finally total costs of illness due to lead, cadmium, and arsenic were derived. The results indicate that among chronic diseases, four illnesses were related to lead and six and five illnesses were related to, respectively, cadmium and arsenic. The total socio-economic costs of the illnesses which were found to be related with three heavy metals were about 23.7 trillion won and the total costs of illnesses caused by blood concentration of lead, cadmium, and arsenic among the public were 165.0 billion, 346.8 billion won, and 341.9 billion, respectively. The contribution of this study lies in providing reliable information regarding costs of illness which would be a lower bound for the cost due to heavy metals and providing an useful tool to judge the effect of food and health policies dealing with other hazardous substances.

산업연관모형을 이용한 농자재산업의 경제적 파급효과 분석

본 연구에서는 산업연관분석을 바탕으로 수요측모형과 공급측모형의 결가를 비교ㆍ분석하여 농자재산업의 중요성을 살표보고자 하였다. 기존의 다른 유사연구와 비교하여 볼 때, 본 연구의 차별성은 일반적인 생산유발효과모형뿐만 아니라 공급지장효과모형을 사용하여 농업부문에 있어서 농자재산업의 중요성을 재조명하였다는 것이다. 결과를 보면, 농자재산업의 공급지장효과는 같은 금액의 변화가 일으키는 생산유발효과보다 상대적으로 큰 것으로 나타났다. 즉, 농자재산업부문의 생산량 증가가 가져오는 다른 산업부문에 미치는 생산유발효과보다 공급량 부족으로 인해 생기는 다른 산업부문의 생산차잘효과가 훨씬 더 강함을 의미한다. 이는 원천적으로 농자재산업이 전체산업 지도에서 비고적 후방에 위치한고 있기 때문으로 풀이된다. 따라서 농자재산업부문의 농업부문에 있어서 차지하는 비중은 일반적인 접근법인 생산유발계수를 활용한 모형보다는 공급감소모형을 통해 볼 때 그 중요성이 더 확연히 나타나는 것을 알 수 있다.

미역의 안전성 강화에 대한 소비자 효용 측정

진현정 ( Jin Hyun-joung ) 한국식품유통학회 2016 食品流通硏究 Vol.33 No.4

This study tries to evaluate consumer willingness-to-pay(WTP) for sea mustard with enhanced heavy metal safety. The evaluation of WTP was conducted using a contingent valuation method. After setting virtual market for sea mustard with enhanced heavy metal safety, respondents were asked their WTP through 3 types of question : direct question, payment card, and dichotomous choice. The average WTP was calculated using analytical median, nonnegative mean, and truncated mean. The results show that the average WTPs for sea mustard with enhanced safety of lead, cadmium, and arsenic are 1,914, 1,659, and 1,701 Korean won, and the entire consumer utility by measuring household base is, respectively, 35.8, 31.0, and 31.8 billion Korean won. These estimates are equivalent to the consumer utility for enhanced heavy metal safety which will be a valuable information for estimating benefit from policies of heavy metal safety for other seaweeds or marine products. We also confirmed that estimated WTP differs by different question type and calculation method, and direct question method yields the largest value of WTP. This suggests that one can reduce bias for estimating WTP by using the average from different question types and calculation methods.

This study analyses consumer preference and purchasing behavior for rice-noodle and, using the conjoint analysis, examines the main attributes consumers consider when purchasing the commodity. In order to set up the attributes and levels in the conjoint analysis, what producers want to know regarding consumer purchasing behavior was investigated through a survey toward rice companies. It was revealed that the most important attribute producers are interested in is ``price``. To check whether or not the results of the conjoint analysis vary depending on the setting of price range, two different conjoint commodity profiles with dissimilar range of price levels were presented toward survey respondents. Empirical results show that through the two different conjoint investigations, price is the most important attribute consumers concern, followed by ``country of origin`` and ``brand``. The order of the importance among the three attributes was maintained regardless of changes in the price interval. The results also revealed that across the two different conjoint surveys, domestic rice as a raw material was preferred to imported rice, while the results were mixed for the brand. It indicates that if the price variation is not large among conjoint commodity profiles, small and medium enterprises may have competitiveness in the market, while if not, large corporation is preferred by consumers. The results of this study may provide useful information regarding consumer preference and purchasing behavior in the rice-noodle market, the main attributes consumer concern when they purchase the product, and promotion of rice-noodle consumption.

This paper analyzes factors that affect purchasing intention for Gluten-free food by female undergraduate and graduate students. We included independent variables such as awareness of the food, involvement for healthy dietary life, attitude toward the food, experience of chronic indigestion, experience of weight control, and demographic variables. This study is the first, as far as we know, to study consumer behavior, attitude, and intention regarding gluten-free food. Our results indicate that respondents who answered ``not aware`` were larger than those who answered ``aware`` for the food. It also appeared that the half of respondents who answered ``yes`` for intake experience of the food appraised the experience positively. The reason with highest frequency respectively of intake and not intake was ``to enhance health`` and ``don``t see the necessity.`` The result of binomial logistic regression model suggests that awareness of gluten-free food, involvement for healthy dietary life, attitude toward the food, experience of chronic indigestion, experience of weight control affect purchasing intention toward gluten-free food, while household income level is not statistically significant.
