Journal Article
Jim LeeThis paper reexamines the determinants of firm performance and, in particular, the role that firm size plays in profitability. A fixed‐effects dynamic panel data model for over 7,000 US publicly‐held firms during the period 1987–2006 provides evidence that profit rates are positively correlated with firm size in a non‐linear manner, holding an array of firm‐ and industry‐specific characteristics constant. In addition, industry‐specific fixed effects play a negligible role in the presence of firm‐specific fixed effects.

Yuxia HuangThis paper investigates the spatial dimension of socioeconomic and demographic factors behind COVID-19 vaccine hesitancy. With a focus on a county with considerable sociodemographic diversity in the state of Texas, USA, we apply regression models to census-tract-level data of the unvaccinated population. In addition to disparities in accessing the vaccination service, particularly for residents in rural areas, empirical results confirm under-vaccination among lower socioeconomic neighborhoods and communities with signs of distrust in government. The spatial model regressions further underscore the impact that vaccine hesitancy among residents in one community spread to its nearby communities. This observed spatial spillover effect is attributable to the geographic interactions of similar socioeconomic groups.
