Fixed Costs and the Product Market Treatment of Preference Minorities
研究了市场结果是否对偏好少数群体存在偏见，通过美国广播电台市场的进入模型估计固定成本，发现白人和非西班牙裔听众的福利权重显著高于黑人和西班牙裔听众。
We clarify the sense in which the market outcome may be biased against preference minorities, and estimate the degree of bias using an empirical model of entry into American radio broadcasting markets. Listening model estimates are used to infer fixed costs, and these estimates are then used to compute optimal station configurations as well as the welfare weights on different groups that rationalize the observed configuration. Welfare weights are 2 to 3 times higher for whites than for blacks, and 1.5 to 2 times higher for non‐Hispanic than for Hispanic, listeners. We explore the role of ‘importing’ and ‘exporting’ patterns in generating these findings.
