Estimating household resource shares: A shrinkage approach
指出集体模型在估计家庭内部资源份额时面临标准误大、估计不稳定的问题，并提出一种收缩策略来稳定估计，有助于分析家庭内部福利和贫困。
Collective models identifying resource shares are promising tools to analyze intra-household welfare and poverty. However, their empirical application has proven difficult in practice as authors contend with large standard errors and unstable estimates. This paper uses a prominent framework to show how a common feature of the structure of these models makes the task so difficult and proposes an empirical strategy to stabilize the estimates.
