We present empirical evidence on a firm’s decision to eliminate a product from a multi-product line, in a market with rapid product turnover, using weekly micro-level data from a major metropolitan movie market. While film offerings are broadly similar across the market, the timing for removing a specific film varies at the theater level. Theaters are more likely to end a film’s run when the nearest competitor is showing the same film and is owned by the same chain; a film is more likely to survive when the nearest theater is showing the film, but is under different ownership. Theater- and movie-specific factors affect a film’s run length, including the film’s within-theater relative revenues, number of screens, and film rating.

我们使用来自主要大都市电影市场的每周微观数据，提供关于公司决定在产品周转迅速的市场中从多产品线中淘汰产品的经验证据。虽然整个市场的电影产品大致相似，但删除特定电影的时间因影院而异。当最近的竞争者正在放映同一部电影并且属于同一连锁店时，剧院更有可能结束电影的放映；当最近的剧院放映电影时，电影更有可能存活下来，但所有权不同。剧院和电影的特定因素会影响电影的放映长度，包括电影在剧院内的相对收入、银幕数量和电影评级。
