Modeling Charitable Giving Using a Box-Cox Standard Tobit Model
指出以往研究慈善捐赠的模型不适用于近期联邦税务数据，开发了带Box-Cox变换的Tobit模型，得到的价格弹性和预期捐赠额与常用模型不同，且样本权重提供了重要政策启示。
There is a large literature investigating the determinants of charitable giving, in particular, price and income elasticities. We find that many of the most often reported results from this literature rely on a model specification that is inappropriate when applied to recent Federal Tax File data. We develop a standard Tobit model with a Box-Cox transformation parameter that nests a number of other specifications. The Box-Cox model yields estimates of price elasticities and expected charitable contributions that differ from those obtained using the typical specification. Additionally, we find that the use of sample weights provides potentially important policy insights. Copyright 1991 by MIT Press.
