One of the most pressing questions in economics is “why are some countries richer than others?” One methodology designed to help answer the question is known as “Development Accounting,” a framework that organizes the determinants of income into two categories: differences in inputs and differences in efficiency. The objective of our work is to study to what extent differences in the levels of pollution can help explain income differences across countries. To do this, we adjusted a factor-only model to allow us to enter PM2.5, a measure of pollution that tracks the concentration of fine particulate matter in the air and looked to see if the model’s predictive power improved. We ultimately find that we can improve the model’s success in predicting GDP by .5 - 6%. Thus, pollution is unlikely to be a major force in understanding cross-country income differences, but it can be used with other economic factors to potentially magnify its impact with other additions in the future.

Pediatric anxiety disorders are highly prevalent and while pharmacological intervention seems to be an effective treatment, the validity of reported adverse side effects remains unclear. <br/><br/>Objective: To analyze the nature of evidence regarding adverse side effects in the pharmacological treatment of pediatric anxiety disorders. <br/><br/>Approach: A search using Google Scholar, PubMed, and PsychInfo was conducted for meta-analyses of pharmacological treatment of pediatric anxiety disorders as well as randomized controlled trials. The focus was on adverse events.<br/><br/>Results and Conclusion: Reportings of a limited number of adverse events were found among resources available to clinician and patient informed sources to inform pharmacological treatment of pediatric anxiety disorders. Only a small fraction of adverse side effects were found in the research literature. This finding raises concerns about making informed decisions to treat pediatric anxiety disorders with pharmacotherapy.

The esports scene has been constantly evolving ever since its inception in the early 1970s, growing from small arcade based tournaments to the multibillion dollar industry that can be observed today (Bountie Gaming, 2018). In fact, the term esports was not widely used until the early 2000s, decades after the first gaming tournaments had taken place. Decades prior, the earliest large-scale gaming tournament was hosted by Atari in 1980 for the game ​Space Invaders ​ . While still primitive by today’s standards, games such as ​Space Invaders ​ inspired fierce competition and effectively laid the foundation for what would grow into the booming industry that we see today (Edwards, 2013).
