What is the formula for measuring price elasticity of demand? percentage change in price / percentage change in quantity demanded percentage change in quantity demanded / percentage change in price change in quantity demanded / change in price change in price / change in quantity demanded when the price elasticity coefficient is less than 1, the percentage change in quantity demanded is the change in price. when the price elasticity coefficient is equal to 1, the percentage change in quantity demanded is the change in price. when the price elasticity coefficient is greater than 1, the percentage change in quantity demanded is the change in price?

There are three factors that can affect the shape of the treasury yield curve (r* t , ip t , and mrp t ) and five factors that can affect the shape of the corporate yield curve (r* t , ip t , mrp t , drp t , and lp t ). the yield curve reflects the aggregation of the impacts from these factors. suppose the real risk-free rate and inflation rate are expected to remain at their current levels throughout the foreseeable future. consider all factors that affect the yield curve. then identify which of the following shapes that the us treasury yield curve can take. check all that apply.a. downward-sloping yield curveb. upward-sloping yield curvec. inverted yield curve
