May 12, 2014 · This is the next video on Applied Econometrics: Difference-in-Differences. This video borrows extensively from Ted Miguel's lectures at UC Berkeley. The one-tailed probability of getting a difference this large just by chance is only .0013, so reject the null. We would also reject if the alternative was 2-tailed; the two-tailed probability is only .0027 and the 99% confidence interval for the difference does not include 0.

Note that this is a more general formulation of the difference in differences regression which allows for different timings of the treatment for different treated units. As was pointed out correctly in the comments your proposed solution c) does not work out due to collinearity with the time dummies and the dummy for the post-treatment period. Stata calculates the difference (diff) as prop(0) - prop(1), or proportion of non-religious people who answered true minus proportion of religious people who answered true. Thus the hypothesis that religious people are less likely to answer true is Ha: diff > 0 and the very low p-value associated with it suggests we should reject the null and ...

Suppose a state implements a health policy law that is aimed at improving the health of the elderly (age 65 and older). The outcome is a binary variable. There four other predictor variables. I am reanalyzing a previous study. In the previous study, they used a difference-in-differences estimator in a logistic regression, while controlling for the four predictors. With the indicators for Treatment and Time, the model is: Jul 10, 2018 · Difference-in-differences is gaining popularity in higher education policy research and for good reason. Under certain conditions , it can help us evaluate the effectiveness of policy changes. The basic idea is that two groups were following similar trend lines for a period of time.

Difference in differences (sometimes 'Difference-in-Differences', 'DID', or 'DD') is a technique used in econometrics that measures the effect of a treatment at a given period in time. It is often used to measure the change induced by a particular treatment or event, though it may be subject to certain biases (mean reversion bias, etc.).

The treatment effect is $\delta$, the implicit assumption is that the treatment effect is constant over time but this can be relaxed if needed. $\endgroup$ – Andy Aug 13 '14 at 14:35
