Callaway and Sant'Anna (2021), 'Difference-in-Differences with Multiple Time Periods', as in the did package's documented example on its county panel (2003-2007): estimate the group-time average treatment effects ATT(g,t) of a state minimum-wage increase on log county teen employment, for each adoption cohort (2004, 2006, 2007) and each period from 2004 to 2007, using the never-treated counties as the comparison group, no covariates and the package's default (varying) base period. Report the group-time effects.
Using Callaway and Sant'Anna's (2021) staggered difference-in-differences estimator on the county panel (500 units, of which 309 are never-treated), comparing each treated cohort to never-treated counties without covariates: ### Overall Average Treatment Effect - **Overall ATT**: -0.0399513 (SE: 0.0119411; 95% CI: [-0.0633554, -0.0165472]) --- ### Group-Time Average Treatment Effects ATT(g,t) #### Cohort 2004 (20 counties) - **2004 (t = 2004, e = 0)**: -0.0105032 (SE: 0.0228824) - **2005 (t = 2005, e = 1)**: -0.0704232 (SE: 0.0353493) - **2006 (t = 2006, e = 2)**: -0.137259 (SE: 0.0377078) - **2007 (t = 2007, e = 3)**: -0.100811 (SE: 0.0349882) #### Cohort 2006 (40 counties) - **2004 (t = 2004, e = -2, pre-treatment)**: 0.00652011 (SE: 0.0233194) - **2005 (t = 2005, e = -1, pre-treatment)**: -0.00275082 (SE: 0.0184849) - **2006 (t = 2006, e = 0)**: -0.00459461 (SE: 0.0182213) - **2007 (t = 2007, e = 1)**: -0.0412245 (SE: 0.019524) #### Cohort 2007 (131 counties) - **2004 (t = 2004, e = -3, pre-treatment)**: 0.0305067 (SE: 0.0148852) - **2005 (t = 2005, e = -2, pre-treatment)**: -0.00272589 (SE: 0.0172891) - **2006 (t = 2006, e = -1, pre-treatment)**: -0.0310871 (SE: 0.0186418) - **2007 (t = 2007, e = 0)**: -0.0260544 (SE: 0.0171051) --- ### Identification and Diagnostics - **Parallel trends**: Pre-treatment placebo ATT mean is -0.00059695767393341 (SE: 0.00682527115146348), which is close to zero and supports the parallel trends assumption prior to adoption. Ressalvas: Identification relies on the parallel trends assumption holding between treated cohorts and the 309 never-treated counties in the absence of treatment. Effects exhibit substantial heterogeneity across adoption cohorts: cohort 2004 experiences larger negative employment impacts than later cohorts (2006 and 2007).

- fonte primária · The did package's pkgdown home page (version badge 2.5.1), section on mpdta: summary(out) prints 'Group-Time Average Treatment Effects' (Group, Time, ATT(g,t), Std. Error) and summary(aggte(out, type = 'dynamic')) prints the overall event-study ATT. Read from the HTML text on 2026-10-15. The SEs are multiplier-bootstrap SEs and differ from the 2026-10-14 research note's copy (0.0243 and 0.0203 there, 0.0246 and 0.0219 now), so they are recorded and never required. The point estimates are deterministic group means; the SEs are multiplier-bootstrap draws, recorded and never required (the target's SE policy). Recorded before the tool was run on these cells: the cells were committed in the pending spec (75c3415) and the tool probed only after that commit.

Callaway and Sant'Anna (2021), 'Difference-in-Differences with Multiple Time Periods', as in the did package's documented example on its county panel (2003-2007): estimate the group-time average treatment effects ATT(g,t) of a state minimum-wage increase on log county teen employment, for each adoption cohort (2004, 2006, 2007) and each period from 2004 to 2007, using the never-treated counties as the comparison group, no covariates and the package's default (varying) base period. Report the group-time effects.
mpdta(agent)The did package's example panel mpdta (Callaway and Sant'Anna 2021): county-level teen employment in 500 U.S. counties, 2003-2007, one row per county and year. Some states first raised their minimum wage in 2004, some in 2006 and some in 2007; the others did not in the window. Columns: countyreal, the county id; year; lemp, the log of county teen employment; lpop, the log of county population; first_treat, the year the county's state first raised its minimum wage (2004, 2006 or 2007; 0 for counties never treated in the window); treat, 1 for counties in states that raised it at some point in the window.

Resumo do raciocínio, como declarado pelo modelo**My Thought Process on Estimating Group-Time Average Treatment Effects** Right, so the core task here is to estimate the group-time average treatment effects, or ATT(g,t) as Callaway and Sant'Anna (2021) refer to them. I'm looking at the impact of state minimum wage increases on log county teen employment (`lemp`), using the `mpdta` county panel dataset. This is a standard staggered adoption difference-in-differences setup, and I need to be precise about the parameters. My adoption cohorts of interest are explicitly stated: 2004, 2006, and 2007. For the counterfactual, I'll be using the `never_treated` group as my comparison. The dependent variable is `lemp`, and my units of observation are `countyreal` over `year`. The crucial variable for identifying the timing of treatment for each county is `first_treat`. Now, I need to figure out the best tool for this job within the available framework. I'm aware of `infer.did_staggered` and that seems like the most direct and appropriate function for this type of analysis, given its specific design for staggered adoption DiD. I've already mentally (or actually, if I were in an interactive session) pulled up the arguments for `infer.did_staggered` to ensure I'm specifying it correctly: * `dataset`: This will be `'mpdta'`, as that's the data I'm working with. * `y`: The outcome variable is clearly `'lemp'`. * `unit`: My observational units are counties, specified as `'countyreal'`. * `time`: The time dimension is `'year'`. * `first_treat`: This is the key variable indicating when each county adopted the policy, so it's `'first_treat'`. * `control_group`: The instructions clearly state to use `'never_treated'` as the comparison group. * `level`: I'll set the confidence level to `0.95` for standard hypothesis testing. * `n_boot`: The default number of bootstrap iterations is usually sufficient, but I'll note it's a parameter I can adjust if needed for precision or computational time. * `seed`: Setting a `seed` to `0` is good practice for reproducibility of any random processes, like bootstrapping. My next step, or concurrent thought, is to ensure I have the necessary skill loaded. I'd either load the `differences-in-differences` skill explicitly or verify that `infer.did_staggered` is accessible through my current environment. Essentially, I'm confirming I have the right tool and know how to use it with the correct inputs to get the ATT(g,t) estimates I need.

Resumo do raciocínio, como declarado pelo modelo**My Thought Process** So, here's what's going through my head. I've been looking at this `mpdta` dataset, and I want to dive deeper into how the `lemp` variable behaves, specifically within the context of `countyreal` units and across `year` time periods. The key element I'm interested in is how the `first_treat` variable acts as a marker for when treatment begins, and I want to isolate the impact on those who were `never_treated` to serve as my baseline. To do this, I'm going to call the `infer.did_staggered` function. I need to make sure I pass in all the correct arguments: the `dataset` is indeed "mpdta", the outcome variable `y` is "lemp", my unit of observation `unit` is "countyreal", and the temporal dimension `time` is "year". Crucially, the indicator for the start of treatment is "first_treat", and my reference group, the control, is defined by "never_treated". This setup should allow me to properly execute a staggered difference-in-differences analysis, which is exactly what I need here.

call_bf29bc1fgemini-3.8-flashFim:STOP32.669 ms16484 de entrada · 935 de saída · 3294 de raciocínio · 12619 em cacheResumo do raciocínio, como declarado pelo modelo**My Thought Process on Estimating Group-Time Average Treatment Effects of Minimum Wage Increases** I've carefully reviewed the user's request, which asks me to estimate the group-time average treatment effects (ATT(g,t)) of state minimum wage increases on log county teen employment. The core of this task involves using the Callaway and Sant'Anna (2021) method, as implemented in the `did` package, specifically employing the county panel data from 2003-2007 provided as an example. I need to consider three distinct adoption cohorts (2004, 2006, and 2007) and estimate the effects for each period from 2004 to 2007, treating the never-treated counties as the comparison group, without covariates, and using the default varying base period. The ultimate goal is to report these group-time effects. Upon executing the relevant `did` package functions, I've obtained a table detailing these group-time ATT estimates, labeled `att_gt`. I'm now going through this table systematically to extract the requested information for each cohort and time period. For the **2004 cohort**, I see the following estimates: * In 2004, the ATT is -0.0105032 (with a standard error of 0.0228824). This period is marked as `post: true` and `e: 0`, meaning it's the first period after treatment adoption. * In 2005, the ATT is -0.0704232 (SE = 0.0353493). This is `post: true` and `e: 1`, the second period post-adoption. * In 2006, the ATT is -0.137259 (SE = 0.0377078), `post: true` and `e: 2`. * In 2007, the ATT is -0.100811 (SE = 0.0349882), `post: true` and `e: 3`. Moving on to the **2006 cohort**: * In 2004, the ATT is 0.00652011 (SE = 0.0233194). This is `post: false` and `e: -2`, indicating a pre-treatment period. * In 2005, the ATT is -0.00275082 (SE = 0.0184849). This is also `post: false` and `e: -1`, another pre-treatment period. * In 2006, the ATT is -0.00459461 (SE = 0.0182213), now `post: true` and `e: 0`. * In 2007, the ATT is -0.0412245 (SE = 0.019524), `post: true` and `e: 1`. Finally, for the **2007 cohort**: * In 2004, the ATT is 0.0305067 (SE = 0.0148852), marked as `post: false` and `e: -3` (pre-treatment). * In 2005, the ATT is -0.00272589 (SE = 0.0172891), `post: false` and `e: -2` (pre-treatment). * In 2006, the ATT is -0.0310871 (SE = 0.0186418), `post: false` and `e: -1` (pre-treatment). * In 2007, the ATT is -0.0260544 (SE = 0.0171051), `post: true` and `e: 0`. I also have an overall ATT estimate, which represents the average effect across all post-adoption cohort-periods. This value is -0.0399513, with a standard error of 0.0119411 and a 95% confidence interval of [-0.0633554, -0.0165472]. This overall estimate is identified by the key `call_e841b472:att`. To ensure the validity of the method, I've reviewed the diagnostic tests. The pre-trend mean is -0.00059695767393341 (SE: 0.00682527115146348). This suggests that, on average, there were no significant trends in log county teen employment in the years prior to treatment adoption among the treated groups compared to the never-treated group, which supports the parallel trends assumption. The diagnostics also show that there are 3 cohorts included in the analysis, and the comparison group consists of 309 never-treated counties out of a total of 500 units. Regarding the output format and rules: I need to provide a concise summary in English, as the original question was in English, and adhere to Rule 7, which states the answer should be short and direct, including the estimate with its uncertainty, the identification design, and potential limitations. I must also list all quoted figures using their references and any diagnostics that limit the conclusion in caveats. Therefore, my final output will present the group-time effects as requested, along with the overall ATT, the identification strategy (staggered difference-in-differences using never-treated counties), and the pre-trend diagnostic as support for the parallel trends assumption, while also noting potential caveats. The overall ATT, identified by `call_e841b472:att`, will be central to the summary. I've confirmed all numbers are directly from the tool output or the question itself, and no calculations have been performed. I will use standard English punctuation, including decimal points, as the question was in English.

Using Callaway and Sant'Anna's (2021) staggered difference-in-differences estimator on the county panel (500 units, of which 309 are never-treated), comparing each treated cohort to never-treated counties without covariates: ### Overall Average Treatment Effect - **Overall ATT**: -0.0399513 (SE: 0.0119411; 95% CI: [-0.0633554, -0.0165472]) --- ### Group-Time Average Treatment Effects ATT(g,t) #### Cohort 2004 (20 counties) - **2004 (t = 2004, e = 0)**: -0.0105032 (SE: 0.0228824) - **2005 (t = 2005, e = 1)**: -0.0704232 (SE: 0.0353493) - **2006 (t = 2006, e = 2)**: -0.137259 (SE: 0.0377078) - **2007 (t = 2007, e = 3)**: -0.100811 (SE: 0.0349882) #### Cohort 2006 (40 counties) - **2004 (t = 2004, e = -2, pre-treatment)**: 0.00652011 (SE: 0.0233194) - **2005 (t = 2005, e = -1, pre-treatment)**: -0.00275082 (SE: 0.0184849) - **2006 (t = 2006, e = 0)**: -0.00459461 (SE: 0.0182213) - **2007 (t = 2007, e = 1)**: -0.0412245 (SE: 0.019524) #### Cohort 2007 (131 counties) - **2004 (t = 2004, e = -3, pre-treatment)**: 0.0305067 (SE: 0.0148852) - **2005 (t = 2005, e = -2, pre-treatment)**: -0.00272589 (SE: 0.0172891) - **2006 (t = 2006, e = -1, pre-treatment)**: -0.0310871 (SE: 0.0186418) - **2007 (t = 2007, e = 0)**: -0.0260544 (SE: 0.0171051) --- ### Identification and Diagnostics - **Parallel trends**: Pre-treatment placebo ATT mean is -0.00059695767393341 (SE: 0.00682527115146348), which is close to zero and supports the parallel trends assumption prior to adoption. Ressalvas: Identification relies on the parallel trends assumption holding between treated cohorts and the 309 never-treated counties in the absence of treatment. Effects exhibit substantial heterogeneity across adoption cohorts: cohort 2004 experiences larger negative employment impacts than later cohorts (2006 and 2007).
