Music subscription case study: investigating the behavioral changes of consumers upon subscription price changes

Started May 3, 2024

Abstract or project description

This paper includes an analysis of the elasticity of various well-known music platforms, such as Spotify, Pandora, and YouTube. Elasticity in economics means the impact that a product change has on a change in consumer behavior. In the context of this paper, I analyze how price changes of music subscriptions affect, if any, consumers' demand. All three music platforms include different music subscription programs with differing prices. Consumers may change their behavior as a result of the price increase, such as canceling subscriptions and choosing alternative products. I explore this change in behavior by documenting changes in the share of paid subscribers by music companies. In addition, this paper also explores other impacts and potential spillover effects of subscription changes.

Melatonin and its effects

Started May 26, 2023

Abstract or project description

Melatonin is a commonly used substance in humans. It is important to understand their effects and safety, so that they can be effectively prescribed to patients with medical issues, such as sleep problems. This project will overview melatonin with respect to the role and process of melatonin in improving sleep and also identify possible adverse effects (AE) of melatonin. PubMed and google scholar were used for literature search to look at 13 articles.   The literature search includes human melatonin sleep experiments and the short-term adverse effects of melatonin. The analysis of melatonin use included the effects on different populations, adults and elderly. This review examines the effectiveness of melatonin and its possible risks for people with sleep quality needs.
