영문 초록

The purpose of this paper is to measure price stabilization effects of fisheries outlook project implemented by the government since 2004. Given the problems associated with the use of a simple coefficient of variation approach, we applied a refined version of coefficient of variation: 1) trend equation is incorporated; 2) a structural change is explicitly taken into consideration. While we found significant price stabilization effects of outlook information on Laver (a kind of seaweed), we found no significant price stabilization effects in the case of Oyster as the presence of stabilization effects tend to be sensitive to the type of coefficient of variation used in the analysis. This suggests a need for careful consideration of pros and cons associated with the use of coefficient of variation in an empirical analysis.
