3. Suppose a straight-line, downward-sloping demand curve shifts right due to an increase in consumer preferences. Is the price elasticity of demand higher, lower, or the same between any two prices on the new (higher) demand curve than on the old (lower) demand curve?
Elasticity of demand = dQ/dP * P/Q
dQ/dP = Slope of demand curve.
Since slope of both curves are same. or there is parallel shift in demand curve.
Price is also same, but quantity has increased for new demand curve. thus, Shifted Demand curve shows that demand is inelastic. or it is more inelastic.

The price elasticity of demand for a downward sloping straight line demand curve is: a. constant as the price changes along the curve b. a number ranging from negative infinity to positive infinity c. given by the ratio of price and quantity d. lower in absolute value as the price drops along the curve
Suppose a firm has market power and faces a downward-sloping demand curve for its product, and its marginal cost curve is upward sloping. If the firm reduces its price, then A. producer surplus increases due to new buyers, but the producer surplus from existing customers declines due to the lower price. B. the sum of producer and consumer surplus remains the same, but surplus value is transferred from the producer to consumers. C. the change in producer surplus is transferred...
Given a downward-sloping aggregate demand (AD) curve and an upward-sloping short-run aggregate supply curve (SRAS), equilibrium occurs where the two intersect. The value on the vertical axis is the equilibrium price level and the value on the horizontal axis is the equilibrium value of real GDP or output. What happens to the economy when AD shifts? It is useful to sketch a graph and show the shift. Suppose, for example, interest rates fall or wealth increases due to a stock...
A. Along a straight-line downward sloping demand curve, as Qd is increasing, the elasticity measurement is: 1. Constant 2. Equal to one 3. Decreasing 4. Increasing The cross-price elasticity of beer for coke is positive, this fact reveals that: 1. Beer and coke are complements 2. Beer is a luxury good 3. Beer and coke are substitutes 4. Coke is an inferior good
in a market with an upward sloping supply curve and a downward sloping demand curve, when there is an excess supply, a. b. c. The actual price must be higher that the equilibrium price. The actual price must be lower that the equilibrium price. The quantity demanded is higher than the equilibrium quantity.
A linear downward-sloping demand curve has price elasticities (in absolute values) that increase as price decreases. remain constant along the demand curve. decrease as price decreases. are greater than or equal to 1. Suppose a hurricane decreased the supply of oranges so that the price of oranges rose from $120 a ton to $180 a ton and quantity sold decreased from 800 tons to 240 tons. What is the absolute value of the price elasticity of demand? 0,11 0.37 9.33...
Consider a monopolist facing a straight line downward sloping demand curve. Suppose that the monopolist has constant marginal cost c>0 and wishes to maximise profit. At the optimal price and quantity choice, if the monopolist were to reduce its price marginally, the total revenue Select one: O a decreases. b. increases. O c. does not change. O d. Not enough information to determine.
Suppose there is a linear downward-sloping demand curve and a linear upward-sloping supply curve for some good. The price of a substitute good decreases and the price of an input to the production process also decreases. Both changes occur simultaneously. Graph the original demand and supply curves, and then graph new curves after the substitute good and input prices decrease. How will the equilibrium price and quantity change after the substitute and input prices decrease? Explain your answer in English...
suppose that the market for product x is characterized by a typical, downward-sloping, linear demand curve and a typical , upward-sloping, linear supply curve. suppose the price of supply is 0.7. will the dead weight loss form a $3 tax per unit be smaller if the absolute value of the price elasticity of demand is 0.6 or if the absolute value of the price elasticity of demand is 1.5?
1) Consider a normal market with a downward-sloping demand curve and an upward-sloping supply curve. Which of the following cases would definitely result in a decrease in consumer surplus? For each case, assume that the market is initially in equilibrium and that everything else is held constant except for the change described in the case Case 1: The supply curve shifts to the left. Case 2: The supp Case 3: The government imposes a binding price ceiling. Case 4: The...
