The objectives of this study are to determine the existence of the day-of-the-week effects in vegetable prices at Garak wholesale market and to investigate the reasons of the day-of-the-week effects. Analysis is conducted on chinese cabbage, red pepper, garlic, onion, carrot and green onion, over the period from January 1995 through December 2003. The multiple regression model with dummy variables is estimated by generalized least squares(GLS) to obtain the average value of daily logarithmic price changes. It is found that significant day-of-the-week effects are present for chinese cabbage, onion and green onion prices, with the pattern of positive price changes on Monday or Tuesday and negative price changes on Saturday. The average daily prices of chinese cabbage, onion and green onion are generally higher in the beginning of the week and lower on weekend. The results imply that producers could make higher returns by shipping their vegetables in the beginning of the week rather than on weekend. The day-of-the-week effects are explained by the degree of perishability, buyers and wholesalers` purchasing pattern, diminishing demand on weekend, and decreased supply on Sunday due to traffic congestion.

우리는 국내 최대 제과회사의 광고 덕분에 가나(Ghana)하면 초콜릿을 먼저 떠올리고, 초콜릿하면 가나를 연상하게 된다. 실제로 가나는 초콜릿의 원료가 되는 카카오의 주요 생산국으로 카카오는 오랫동안 가나의 주요 수출품목 및 환금작물(換金作物)로 자리매김해 왔다. 가나는 인접국가인 코트디브아르(불어로는 Cote d’Ivoire이고 영어로는 Ivory Coast)에 이어 세계2위의 카카오 생산국이며, 다른 생산국들에 비해 프리미엄급 카카오를 생산하는 것으로 유명하다. 본고에서는 카카오의 특성 및 생산과정에 대해 소개하고, 전 세계 및 가나의 카카오 생산 현황을 살펴본 다음 최근에 가나의 카카오 생산량이 크게 증가한 원인에 대해 고찰하고자 한다.

This study primarily aims to examine the current situation of ginseng industry in major countries (China, United States and Canada) and to explore future directions in the development of Korean ginseng industry. To enhance the competitiveness of Korean ginseng, this study suggests more rigorous scientific research on the effects and active ingredients of Korean ginseng, especially whether it contains heating (yang) or cooling (yin) ginsenosides, industry efforts to prevent marketing of counterfeited Korean ginseng, production increase of 3~4 year old ginseng rather than 6 year old to gain a competitive advantage in Korean ginseng price, and product diversification to avoid the problems of overconcentration on red ginseng.
