Children’s Continuous Medicaid Eligibility During Covid-19 and Health Care Access, Use, and Barriers to Care
In this survey study, newly implementing continuous eligibility for children under the FFCRA was associated with reductions in unmet health care needs and no additional changes in health care outcomes overall, with additional benefits for Hispanic children and publicly insured children. This could reflect expected changes under mandatory, national 12-month continuous eligibility for children implemented in January 2024
Children’s Insurance Stability and Coverage Inequities During the Covid-19 Continuous Coverage Provisions
Objectives. To explore the association between the March 2020 Families First Coronavirus Response Act (FFCRA) Medicaid disenrollment freeze during the COVID-19 public health emergency (PHE) and children’s insurance coverage by family income, race/ethnicity, and language. Methods. We used 2015 to 2021 US Medical Expenditure Panel Survey data, comparing monthly coverage for publicly insured children before (2015–2019) and during (2020–2021) the PHE…
Erosion of community complexity increases temperature-dependency of microbial respiration, but not growth, in short-term incubations
Biodiversity loss and climate change are 2 of the most alarming threats to ecosystem functioning and stability. These factors are, however, typically investigated separately, overlooking potential interactions between species extinctions and climate change on ecosystems. Here, we evaluated how different temperature regimes impact the relationship between microbial diversity and ecosystem functioning, in terms of temperature sensitivity of carbon …

Population-level factors associated with maternal mortality in the United States, 1997–2012
Our findings indicate that, in addition to better case ascertainment of maternal deaths, adverse changes in chronic diseases, insufficient healthcare access, and social determinants of health represent identifiable risks for maternal mortality that merit prompt attention in population-directed interventions and health policies

[Bayesian Analysis of Stochastic Volatility Models]
Inequality Constraints in the Univariate GARCH Model
To keep the conditional variances generated by the GARCH (p, q) model nonnegative, Bollerslev imposed nonnegativity constraints on the parameters of the process. We show that these constraints can be substantially weakened and so should not be imposed in estimation. We also provide empirical examples illustrating the importance of relaxing these constraints
Conditional Heteroskedasticity in Asset Returns
This paper introduces an ARCH model (exponential ARCH) that (1) allows correlation between returns and volatility innovations (an important feature of stock market volatility changes), (2) eliminates the need for inequality constraints on parameters, and (3) allows for a straightforward interpretation of the "persistence" of shocks to volatility. In the above respects, it is an improvement over the widely-used GARCH model. The model is applied to…
