I am interested in the authors’ input regarding a few issues that caught my attention. Firstly, the study focuses on short-term effects, analyzing data only up to five years after graduation. While this is insightful, I would appreciate it if the authors could discuss the potential limitations of not having long-term data, especially for graduates who might experience changes in job satisfaction beyond the study’s window.
Additionally, while the study finds that job satisfaction increases most significantly in the academic sector, it does not seem to explore why permanent contracts in academia are perceived differently compared to other sectors. A deeper exploration of sector-specific expectations and career trajectories could further enrich this finding.
Lastly, the study uses fixed-effects regression to control for unobserved heterogeneity, which is a strong methodological approach. However, I wonder if the authors could please elaborate on the potential limitations of this method in estimating causal relationships. While the paper suggests that the effect is likely causal, the fixed-effects model may not fully rule out reverse causality or the influence of unobserved confounders that could also drive changes in job satisfaction.
