The market demand curve of a particular good is downward-sloping. Based on this information, which of the following statements is correct regarding a price-taking firm producing that good? (Justify the answer)

a) The demand curve faced by the firm is downward sloping

b) The firm chooses the price that equals its marginal cost

c) The firm chooses its output such that the marginal cost equals the price

d) A price-taking firm cannot be profit-maximising

Solutions

Expert Solution

Answer : A firm chooses the price that equals the marginal cost.

In a perfectly competitive market, firms are price takers because all the goods sold in this market are homogeneous and perfect substitutes. A price charged by the firm above the market price will lose all its customers and customers will switch to other producers. So the producer is a price taker. The firms will inturn charge a price equal to its marginal cost. It means that when a firm produces an extra unit, it will charge a price equal to the cost of adding a factor inputs to produce that additional unit.

Suppose that in the market for widgets, the supply curve is the typical upward-sloping line, and the demand curve is the typical downward-sloping line.
Suppose that in the market for widgets, the supply curve is the typical upward-sloping line, and the demand curve is the typical downward-sloping line. A tax of $4.80 per unit is imposed on widgets and the price rises by $3.25. The equilibrium quantity before the tax imposition was 400,000 widgets and the equilibrium quantity after the tax is 364,000 widgets. The deadweight loss from the tax isSelect one:A. more than $74,150 but less than $76,600      B. more than $76,600 but less...

The elasticity is inelastic along the line. D. The elasticity is perfectly elastic along the line. 2. The income elasticity for Good A is 0.7, and its cross elasticity with Good B is 0.7.

In an open economy, why is the demand curve in the foreign-currency exchange market downward sloping?...
In an open economy, why is the demand curve in the foreign-currency exchange market downward sloping? A. A depreciation in the domestic currency causes exports to fall and imports to rise and, therefore, net exports to fall. B. A depreciation of the dollar reduces the quantity of dollars demanded in the market for foreign-currency exchange. C. When the value of the domestic currency depreciates, domestic goods become less expensive relative to foreign goods, making domestic goods more attractive to domestic...

Assume that the labor market is competitive, where the labor demand curve is strictly downward sloping and the labor supply curve is strictly upward sloping. (a) Suppose the government imposes a minimum wage on this labor market. Why would the minimum wage cause a deadweight loss (welfare loss)? In what sense is it a loss? (b) How does the deadweight loss depend on the elasticities of the demand and supply curves? Explain. (c) If the minimum wage created a deadweight...

If the demand for labor is reflected in a downward sloping linear demand curve, then successive increases in any binding minimum wage (that is, for example, a binding minimum wage increases from $10.10/hr to $12.10/hr and then from $12.10/hr to $14.10/hr), will result in Multiple Choice no job losses since the demand for labor, particularly unskilled labor, is highly price inelastic.    increasing (as a percentage) job losses, and decreasing total income (or reduced rates of income growth) paid to...

Suppose the demand is a typical downward sloping linear curve and the supply curve is perfectly price elastic. If 3 million tickets are currently sold at a price of $5, approximately how much tax revenue could the government generate from a $1 per unit tax on sellers? The arc-price elasticity of demand between P=$5 and the new equilibrium price is -1.0 (Note: dQ = Change in Q and dP=Change in P) i. Draw a completely labeled D&S graph to show...
