Overview

The overview of this annotated bibliography goes here. Talk about your broad goals for this literature search. What major themes did you aim to address? Throw a few citations in here as well, just to frame up the content below. I view this document as a long form version of my introduction and background sections. Ideally all the writing I do from this point forward is further distilling the abstracts from papers. The annotated bibliography roughly takes the following form in my use, feel free to add/detract as much as you’d like:

Title goes here nice and italicized

Main Findings: The main finding and contribution of this paper to the literature. 1-2 sentences.

Distilled Abstract: A 2-3 sentence recap of the paper.

Annotated Bibliography

You can split the sections below into topic areas and the table of contents up top will repopulate.

Healthcare Utilization and Medicaid Expansion

The effects of public health insurance on health behaviors: Evidence from the fifth year of Medicaid expansion.

Main Findings: Medicaid expansions ↑ preventative care & exercise and ↓ smoking & heavy drinking.

Distilled Abstract: This study observes the relationship between legislative expansions of public health insurance and health behaviors over time through analysis related to the installment of the Affordable Care Act-facilitated Medicaid expansions. The results show that said expansions increase the implementation of certain forms of preventive care, a reduction in heavy drinking, a reduction in smoking and a probabilistic increase in exercise, thereby indicating that the public insurance expansions could reduce harmful health habits in low-income populations over time.

STI Transmission and Medicaid Expansion

The effect of health insurance on sexual health: Evidence from the Affordable Care Act’s dependent coverage mandate.

Main Findings: Dependent coverage mandate ↑ chlamydia incidence for groups that gained coverage.

Distilled Abstract: This study observes that chlamydia rates increased for males and females ages 20-24 relative to comparison groups of males and females ages 15-19 and 25-29 following the ACA dependent coverage mandate. The author also offers evidence of an increase in gonorrhea rates for females in the same age group. They find no evidence that the mandate induced ex ante moral hazard.

Staggered Timing and TWFE Estimate Bias

Difference-in-Differences With Variation in Treatment Timing.

Main Findings: Staggered treatment timing in TWFE estimation introduces bias to estimate by comparing early and later treated units.

Distilled Abstract: This study identifies and decomposes a source of bias in TWFE estimations. The decomposition allows for a diagnostic of quasi-experimental settings to determine whether an estimator robust to the bias introduced by staggered treatment timing is needed.

The Effect of Minimum Wages on Low-Wage Jobs

Main Findings: Minimum wage laws do not have a large impact on low-wage jobs, new DiD method ameliorates staggered timing bias.

Distilled Abstract: This study observes that states’ minimum wage laws do not significantly change the composition of workers in low-wage jobs. The major contribution of this work is a stacked difference in difference estimation strategy which identifies comparisons between treated and never treated units by allowing TWFE to vary by treatment cohort.
