초록
KOBIS통합전산망으로부터 관객 수와 매출액에 관한 영화별 × 광역시도별 × 주별 자료를 채취한 후, 영화에 대한 수요를 확률계수 로짓모형으로 설정하여추정하고, 수요의 가격탄력성을 중점적으로 분석하였다. 영화별 × 광역시도별 × 주별 단위로 추정된 총 13,077개의 가격탄력성 추정치는 -8.585 ∼ -7.402 × 10-6 범위에 넓게 분포하여 영화는 개별 상품에 대한소비자 선호가 아주 다채로운 상품에 해당함을 확인할 수 있었다. 추정치의 표본 평균값은 -0.890, 표본 중위값은 -0.610으로서 한국을 대상으로 한 거시적연구가 보고한 추정치보다는 더 탄력적이지만 국외를 대상으로 한 미시 및 거시적 연구가 보고한 추정치보다는 더 비탄력적이었다.
Abstract
From KOBIS Database compiling administrative and marketing information on every movie on screen in Korea, we constructed weekly data on movie-goers and sales at the individual movie/ province level. We then estimated a random coefficients logit model for cinema demand at the individual movie/week/province level. The 13,077 own price elasticity estimates range widely from -8.585 to -7.402 × 10 , manifesting colorful preferences of individual moviegoers. Sample mean and median of these estimates are -0.890 and -0.610, which are less elastic than the estimates from micro-level and macro-level studies on Spanish, German and Australian markets, and far more elastic than the estimate from a macro-level study on Korean market.
