Covid-19 in Wales: the mental health and wellbeing impact

[…] Welsh Government as mental health is a key determinant of educational success, future earnings, employment, and physical health of an individual. This paper intends to quantify the impact of the COVID-19 pandemic, lockdowns and social restrictions on mental health outcomes using the UK household Longitudinal Study (UKHLS), covering the pre-COVID-19 pandemic period (2009-2019) and […]

Double machine learning for static panel models with fixed effects

[…] fixed effects and unspecified nonlinear confounding. Our simulation study assesses the performance of these procedures using different machine learning algorithms. We use our procedures to re-estimate the impact of minimum wage on voting behaviour in the UK. From our results, we recommend the use of first-differencing because it imposes the fewest constraints on the […]

Friends make us happy: evidence from three European panel studies

[…] accounting for the potential influence of unobserved individual time-constant and time-varying heterogeneity by using random trend models (fixed effects with individual slopes (FEIS)). Thirdly, we inspect the impact of feedback by applying first-difference (FD) models. The results of FE, FEIS, and FD models show that the number of friends has a small positive effect […]

Deprivation’s role in adolescent social media use and its links to life satisfaction

Adolescents spend more time on social media than ever, making it necessary to understand the impact of social media use on their well-being. A largely unexplored, but potentially important, risk factor which may moderate effects of social media on well-being is material deprivation. Using 10-wave longitudinal data from 23,155 adolescents collected between 2009 and […]

Using interactions of area dose and individual exposure to estimate effects of population health interventions

[…] reform on the mental health of benefit claimants. In both cases and in a simulation study, the interactions approach produces more specific, precise and interpretable estimates of intervention effects. We suggest that researchers evaluating population health interventions that are expected to impact on some populations more than others should consider using a dose-exposure interaction design.
