MODEL AVERAGING IN ECONOMICS: AN OVERVIEW
综述了模型平均方法在经济学中的应用，该方法通过考虑模型选择的不确定性来改进实证研究，并以美国各州死刑威慑效果为例进行说明。
Abstract Standard practice in empirical research is based on two steps: first, researchers select a model from the space of all possible models; second, they proceed as if the selected model had generated the data. Therefore, uncertainty in the model selection step is typically ignored. Alternatively, model averaging accounts for this model uncertainty. In this paper, I review the literature on model averaging with special emphasis on its applications to economics. Finally, as an empirical illustration, I consider model averaging to examine the deterrent effect of capital punishment across states in the USA.
