To make decisions about product prices and output, managers need to research the supply and demand of goods, factors affecting demand for goods, and the elasticity of demand, and especially need to analyze factors affecting the price elasticity of demand for a firm’s product (EDP). For goods in general, the price elasticity of demand is influenced by four factors. For a business’s products in particular, this elasticity is also influenced by six factors: market structure market, market demand elasticity, market share, product differentiation, customer loyalty, and reaction of competitors. Businesses need to concentrate on examining the effects of these aspects in order to maximize decision-making.
