FLEXIBLE FORM METHODS FOR MEASURING RENT GRADIENTS*
提出一种实证方法，在消费者对市中心距离偏好不同的情况下测量租金梯度，并推导出租金梯度、自身价格弹性和收入弹性的简便计算公式，同时检验假设偏好相同导致的估计偏差。
ABSTRACT We develop and demonstrate an empirical methodology for measuring rent gradients in the presence of consumers that have varying tastes for distance to the city center. We derive easily calculated measures of rent gradients, own price elasticities, and income elasticities. We demonstrate the ease of calculation of these functions, even in the presence of consumers who have nonidentical preferences. We also demonstrate how to test for bias in rent gradient estimation that arises from assuming identical preference functions.
