This article discusses the concept of price elasticity of demand for phones, alcoholic drinks, and healthcare. It explores the factors that affect demand elasticity and the implications for different types of goods. The demand for phones is highly elastic, except for certain professional needs. Alcoholic drinks have varying levels of elasticity, with some types being more inelastic due to customer loyalty. Demand for healthcare services is income-resilient, but certain types of care, such as preventive care, are more price-sensitive.
