  • The paper studies the degree of international price dispersion for 300 individual goods and services between cities of three country groups over 1999 and 2013, focusing on the role of oil prices in generating deviations from the law of one price. We find that while oil prices did not contribute to the trend in cross-country price dispersion, it does account for within-country price dispersion. Once the oil price effect is subtracted out, the remaining price dispersion between U.S. cities no longer exhibits a noticeable upward trend. If oil prices increase transportation costs, they should increase the deviations from the law of one price, raising price dispersion. Our findings indicate that this effect is more pronounced within a country, while factors such as elasticity of substitution and other trade barriers are likely to matter more in price dispersion across borders. We view our results as complementary to those that emphasize the role of time-varying factors in accounting for price dispersion.

  • A chained option is a barrier option activated in the event that the underlying asset price crosses barrier or barriers prior to maturity in a specified order. In this paper, we study the pricing of chained options with the quanto property called the "Quanto chained option". A quanto chained option is a chained option starting at time when the foreign exchange rate has the multiple crossing of specified barriers. We provide closed-form formulas for valuing the quanto chained options based on probabilistic approach.

  • This study was to investigate the consumption pattern, behaviors, and motivational attitudes related to fruit and vegetables. Data were collected from 344 mothers whose children were attending an elementary school and a middle school in Kimcheon. The average vegetable expenses were under 10,000 won per week. The frequency of purchasing vegetables was 2-3 times a week. Housewives usually bought the vegetables at local markets and grand shopping centers. As for buying vegetables, housewives considered the organic vegetables, preference, price, and nutrition in order. In the family, the vegetables were favored by husbands most and by sons least. The average fruit expenses were under 10,000 won per week. The frequency of purchasing fruit was 2-3 times a week. Housewives usually bought the fruit at local markets and grand shopping centers. As for buying fruit, housewives considered preference, price, and nutrition in order. The fruit were favored by all members most and by husbands least. Housewives identified barriers to increasing vegetables and fruit consumption, including preference for other foods, lack of availability, cost, and time and effort to prepare. Several implications for nutrition interventions were suggested. First, a key motivation for these women was eating healthy food when they are pregnant, suggesting a persuasive appeal to use in interventions. Second, review of the women's current behaviors led to an identification of four specific behaviors that had the most potential for increasing overall consumption. Finally, the findings suggested ways in which nutrition interventions could address each of the barriers identified.

  • The Republic of Korea (ROK) has made many efforts to reduce greenhouse gases through a legal framework, making obligations to reach domestic and overseas targets via the Paris Convention in 2015. China recently launched a nation-wide emission trading system (ETS) and has considered extending this ETS to include the ROK. This study examines the possibility of linking the ETS between ROK and China by considering the institutional design elements of the ETS. Additionally, this study provides policy implications to reach Korea's overseas reduction target. For the research methodology, the design elements of both the ROK and China policies were analyzed by categorizing their standard design elements based on the International Carbon Action Partnership. This paper focuses on four main barriers (cap type, borrowing, offset and price ceiling) based on their environmental benefits and analyzes the challenges to combining the design elements between the ROK and China systems. The two ETS commonly share the same cap types, and there is similar institutional progress regarding the offset and price ceiling. In addition to this, note that China has a borrowing system that is opposite to the borrowing system in ROK. According to these findings, there are major challenges to linking the ROK and China systems due to differences in the major design elements. Thus, it is necessary to modify the Korean domestic borrowing system and understand the Chinese institutional processes related to environmental negotiation to achieve further cooperation.

  • External barrier options are two-asset options with stochastic variables where the payoff depends on one underlying asset and the barrier depends on another state variable. The barrier state variable determines whether the option is knocked in or out when the value of the variable is above or below some prescribed barrier level. This paper derives the explicit analytic solution of the chained option with an external single or double barrier by utilizing the probabilistic methods - the reflection principle and the change of measure. Before we do this, we examine the closed-form solution of the external barrier option with a single or double-curved barrier using the methods of image and double Mellin transforms. The exact solution of the external barrier option price enables us to obtain the pricing formula of the chained option with the external barrier more easily.

  • The purpose of this study was to identify factors influencing the consumption of calcium-rich foods among adolescents. A total of 96 adolescents divided into twelve focus groups were investigated during April to May 2000 in Busan. Focus group discussions were audio-taped, transcribed and analyzed using a grounded theory approach. Key factors influencing the consumption of calcium-rich foods were taste, food type, body image, and family. Motivators among the factors were taste, flood type, body image, health, family and perception, and barriers were taste, flood type, location, friends, price, weather and lactose intolerance. Taste, flood type, location and weather were found to be both motivators and barriers of consumption of calcium-rich floods according to circumstances. Some of these factors varied in importance by gender and age. Younger adolescents were more strongly influenced by taste and family than older ones. Older adolescents were strongly influenced by body image, convenience and perception. These findings could be used as a guideline for adolescents to consume calcium-rich foods.

  • This paper concerns barrier option of American type where the underlying price is monitored during only part of the option's life. Analytic valuation formulas of the American partial barrier options are obtained by approximation method. This approximation method is based on barrier options along with exponential early exercise policies. This result is an extension of Jun and Ku [10] where the exercise policies are constant.

  • The effect of change in exchange rates on an economy is very important, especially, to a small open economy like South Korea. I explore whether Free Trade Agreements (FTAs) have positive influences on exchange rate-pass through import price of import market for fishery products in South Korea. Competition among FTA partners is enhanced after FTAs are effective. I expect that the extent to which are exchange rate pass-through (hereafter, ERPT) into import price of fishery products (in terms of Korea currency) would be reduced since the import market for fishery products in South Korea is an oligopolistic market. Specifically, I investigate two research questions with six South Korea's FTA partners-Norway, Thailand, Peru, U.S., China and Vietnam. First, whether the extent to which are exchange rate pass-through into import price of fishery products from six FTA partners would decrase in the post-FTA era; seconds, the size of reduction has a negative relation with the size of their market share in the import market for fishery products in South Korea if it decreases. The empirical results indicate that the degree of ERPT into import price from other FTA partners than Norway has been reduced after FTA, statistically and significantly; however, I do not find the evidence that the size of reduction is related to their market share. The findings in this study imply that FTAs have negative effects on producers' economic welfare in South Korea's fishery industry by reducing the extent to which are exchange rate pass-through as well as reducing tariff barriers.

  • Internet vendors are gradually realizing the importance of "locking-in" online customers in order to ensure profitability. Erection of switching barriers increases customers'lock-in and in turn may result in their willingness to pay price-premium for the same service. However, raising customer lock-in online is difficult because search costs are very low. Therefore, this study examines the effect of switching barriers (customer satisfaction, perceived value and relative advantage) on switching costs and the effect of switching costs on customer's willingness to pay more. Since switching costs and consequent relationships may depend upon the type of product therefore the research model in this study is examined for both search products and experience products. Data is collected through an online survey from two websites (one each for search product and experience product). The empirical results show the key role of switching costs in customers' willingness to pay more and the relationships among the four constructs. The theoretical and practical implications of this study are also discussed.
