Recently, consumers’ interest in food safety has increased rapidly, and it may affect consumer preference and the food production process. Considering that high-income countries have stricter regulations on food production and greater consumer preferences for safe food products, countries’income level might have an important role in determining the quality of food products. Therefore, higher-income countries have possibly been exporting their food products to similar-income-level countries because of the greater consumer preference for safer food products. In this paper, we examine how income similarity between countries affects the trade flow of food products using a large-panel data set covering 2000 to 2018. We found that income similarity has an important role in the trade of food products and the Linder effect is larger than in the other industries we consider in this study. These results support the Linder hypothesis and imply that we need to consider income similarity an important variable in future research in food trade and when establishing a food exporting strategy.

교역국의 문화적 특성이 식품무역에 미치는 영향 분석

조규대,임태인,김윤형 한국농업경제학회 2023 농업경제연구 Vol.64 No.1

The previous studies have suggested that the cultural characteristics of a country could affect consumer preference attitude toward innovation and international trade. To examine this effect, Hofstede’s multidimensional index of national culture has been popularly used. This paper focuses on the question of how the Hofstede individual cultural indices affect the international food trade using a gravity equation. The results show that the individual cultural characteristics have different effects on the food trade. An increase in the power distance, uncertainty avoidance, and masculinity index is negatively related to food exports, while an increase in the individualism and indulgence index is positively correlated with food exports. On the other hand, the power distance, and masculinity index have been positively related to the food imports, whereas individualism, uncertainty avoidance, and indulgence index have been negatively related to the food imports. Considering the magnitude of the effects in each index, we find that high uncertainty avoidance, long term orientation, and masculinity index restrain the food trade, while the high power distance index tends to increase food imports. Finally, individualism and indulgence index have a greater effect on food exports than imports.

While corruption in importing countries is generally regarded as a trade barrier that increases transaction costs and hampers trade, some argue that in cases where institutional and administrative inefficiencies are severe, corruption may serve as a “grease the wheels” mechanism that mitigates such inefficiencies. This study analyzes a balanced panel dataset of 13,838 observations on food exports from the world’s top 10 food-exporting countries to various importers from 2002 to 2018, employing a gravity model framework. The results indicate that, overall, corruption in the importing country hinders food exports. Specifically, a one-point increase in the importer's control of corruption index is associated with an approximate 21.58% increase in food exports. Furthermore, an examination of non-linear relationships suggests the possibility of an inverted U-shaped relationship between the level of corruption and food exports. To test the hypothesis that corruption may play a lubricating role in countries with extremely poor institutional and administrative quality, the sample was divided based on governance quality. The findings provide partial support for the “grease the wheels” hypothesis in such contexts.

교민이 한국의 과일류 수출에 미치는 영향 분석 - Cragg의 Double Hurdle Model을 이용한 접근

조규대,김인석 한국농업경제학회 2019 농업경제연구 Vol.60 No.1

Recently, the effect of immigrants on international trade has been one of the important research topics in international economics. To examine this issue in connection with the agricultural export of Korea, relevant studies has used the panel tobit model to control the observations having zero value. However, theoretically, the tobit model is highly restrictive because it assumes the same consumption and participation effect of immigrant on trade volume. In this paper, with panel data sets covering three important fruit exports of Korea, we estimate these effects separately using the Cragg’s double hurdle model. The important empirical findings are: First, the Cragg’s model is statistically more proper than the tobit model to handle agricultural export data when there are significant zero observations in the sample. Second, the participation effect of immigrants on trade volume is significant while the consumption effect is not so important. Third, the effect of immigrants on Korea’s fruit exports are much bigger than the general goods suggested in the relevant literature.

소셜벤처 생존요인에 대한 실증연구

조규대,김세현,홍재범 기술보증기금 2025 기술금융연구 Vol.14 No.1

본 연구는 소셜벤처 생존에 영향을 미치는 요인에 관한 실증연구이다. 연구 대상은 2020년과 2021년 2개년 사이에기술보증기금 소셜임팩트 보증을 받은 745개 소셜벤처이며, 종속변수는 보증지원 이후 3년간 부실이 발생하지 않으면생존으로 정의하고, 독립변수는 보증 심사를 위해 실시한 평가자료로 측정하였다. 평가자료는 사회성과 혁신성에 대한다양한 평가 결과로 구성되어 있다. 분석 결과, 소셜벤처 혁신성이 사회성에 비해 수준이 높다. 사회성과 혁신성 모두소셜벤처 생존에 영향을 미치지만, 그 영향은 연차에 따라 다르다. 혁신성에서 경영주 경험과 참여인력 역량은 1, 2,3년에 모두 영향을 미치지만, 경영주 경험은 1년 차에 가장 큰 영향을 미치고, 이후 점차 감소하고 참여인력 역량은1년 차 보다, 2년, 3년 차에 영향이 커진다. 사업진행 수준이나 시장 여건은 2년과 3년 차에 영향을 미친다. 사회성은1년 차에는 생존에 영향을 미치는 항목은 없지만, 2년 차는 사회적 비즈니스모델의 사회적 수용이, 3년 차에는 사회적성과 창출이 영향을 미친다. 소셜벤처의 생존에 창업자 역량과 참여인력 역량, 사업진행 상황이나 시장 여건도 중요하지만, 이와 함께 사회적성과 창출도 중요하다. This study is an empirical study on factors affecting the survival of social ventures. The subjects ofthe study are 745 social ventures that received the Technology Guarantee Fund Social Impact Guaranteebetween 2020 and 2021. The dependent variable is defined as survival if no default occurs for threeyears after the guarantee support, and the independent variable is measured by evaluation data conductedfor the guarantee review. The evaluation data consists of various evaluation results on sociality andinnovation. The analysis results show that the level of social venture innovation is higher than sociality. Both sociality and innovation have a positive effect on the survival of social ventures, but the effectvaries by year. In terms of innovation, both the experience of the manager and the capacity of theparticipating personnel affect the first, second, and third years, but the experience of the manager hasthe greatest effect in the first year and gradually decreases thereafter. The capacity of the participatingpersonnel has a greater effect in the second and third years than in the first year. The level of businessprogress and market conditions affect the second and third years. Sociality does not have any itemsthat affect survival in the first year, but in the second year, the social acceptance of the social businessmodel affects it, and in the third year, the creation of social outcomes affects it. The survival of socialventures depends on the founder's capabilities, the capabilities of the participating personnel, thebusiness progress status, and market conditions, but social outcome creation is also important.

Is An Export Subsidy Socially Beneficial under Corruption?

조규대 한국농업경제학회 2014 農業經濟硏究 Vol.55 No.4

According to the influential model suggested by Brander and Spencer(1985),an increasing export subsidy can increase a market share of the firm inforeign markets and a social welfare of the country under the assumption ofneutral government. In this paper, using the concept of a politically realisticobjective function (PROF). I try to develop a policy decision model when thegovernment decision makers are corrupt. Within this particular setup, thetheoretical finding of the paper shows that a collusion equilibrium can existbetween policy makers and high cost firm. In this case, agricultural export canbe increased with an export subsidy, however, it is not socially beneficial.
