regression adjustmenttime‐varying confoundingDifference-in-differences (diff-in-diff) is a study design that compares outcomes of two groups (treated and comparison) at two time points (pre- and post-treatment) and is widely used in evaluating new policy implementations. For instance, diff-in-...

Alternatively, one can estimate a cross-sectional regression of first differences, (31)Δy=β0+Δu, in which case the treatment effect is given by the intercept β0. With more than one period before and after the event, several options are available. First, one can estimate a level ...
Balancing, Regression, Difference-In-Differences and Synthetic Control Methods: A Synthesis 来自 ideas.repec.org 喜欢 0 阅读量: 585 作者:N Doudchenko,GW Imbens 摘要: In a seminal paper Abadie, Diamond, and Hainmueller [2010] (ADH) develop the synthetic control procedure for estimating the ...
GentrificationWe develop a class of difference-in-differences regression models for the case of multiple transportation interventions that may occur sequentially over time and may generate causal spillover effects within a spatial system. We show how these models can be estimated using tools from ...

It aimed at the difference among within and between groups of control group and treated group to discuss the treatment effects of the household's medical care expenditure after the implementation of NHI. Then we use quantile regression model to estimate the treatment effects of the household's ...
