If some monopolistically competitive firms exit their market after suffering short-run

A firm's short-run average total cost curve is parallel to its short-run average variable
cost curve.
In the long-run equilibrium, both the perfectly competitive firm and the
monopolistically competitive firm produce the output at which MR = MC and charge a
price equal to the average total cost of production.
If the long-run average total cost curve is downward-sloping, then the firm is
experiencing decreasing returns to scale.
A decrease in liabilities will reduce a firm's accounting profit.
Consider a country that produces only two goods: parrots and iguanas. Suppose it is
impossible for this country to increase its production of parrots without producing
fewer iguanas. In this case, its current output combination is efficient.
To maximize profit, a monopolist will produce and sell a quantity such that for the last
unit sold, marginal revenue equals marginal cost, and charges a price given by the
demand curve at that output level.
Assume that the personal computer industry is perfectly competitive. The fact that the
price of personal computers over the last decade has fallen despite increases in demand
signifies that the industry is a decreasing-cost industry.
If a per-unit tax on output sold is imposed on a monopoly's product, the monopolist will
increase its market price by the full amount of the tax.

being in competitive equilibrium.
An increase in the supply of capital, which is a substitute to labor, will lead to a
decrease in the demand for labor.

If the marginal tax rate is greater than the average tax rate, the tax structure is described
as regressive.
Marginal benefit refers to the additional benefit that your activity provides to you.
Each person goes about her daily business seeking to maximize her own self interests.
In doing so, she contributes to the welfare of society at large. This is the idea underlying
Adam Smith's "invisible hand."
Suppose a monopoly is producing its profit-maximizing output level. Now suppose the
government imposes a lump-sum tax on the monopoly, independent of its output. As a
result the monopolist will increase the price of its product to cover its higher cost.
If the demand for a product increases and the supply of the same product increases, the
equilibrium price will increase.
In economics, the term "free market" refers to a market where products are traded but
not sold.

or sellers.

and consumed.
If the demand curve for a product shifts to the left and the supply curve for the product
shifts to the left, the equilibrium quantity will decrease.

prefer organic produce over conventional produce. Which of the following best explains
the effect of these events in the organic produce market?

right. As a result there has been an increase in the equilibrium quantity and an uncertain
effect on the equilibrium price.

been an increase in the equilibrium quantity and an uncertain effect on the equilibrium
price.

been an increase in both the equilibrium price and the equilibrium quantity.
D) The supply curve has shifted to the left and the demand curve has shifted to the
right. As a result, there has been an increase in the equilibrium price and an uncertain
effect on the equilibrium quantity.
