Which of the following statements about the beer industry is correct?

A) Over the last 30 years, technological change has resulted in substantial diseconomies of scale in the industry.
B) In 2000, the minimum efficient scale in the industry was approximately 18 million barrels per year.
C) As a result of an increase in the number of microbreweries, the five largest firms in the industry control less than 50 percent of the market.
D) The market share of microbreweries was estimated to be 20 percent in 1990.

Much of the research on the minimum efficient scale suggests that for many firms the LRAC curve is:

The text considers three methods that can be used to obtain empirical estimates of long-run costs in different industries.Of those three, surveys of expert opinion are considered to be most reliable because they are less subject to bias than the other two methods.

One of the major motivations for labor resistance to productivity enhancing changes in a production process is the resulting threat to job security.

The fact that supermarkets, a land-intensive form of organization, have become the dominant form of grocery store in the United States suggests that there is little or no potential for input substitution in the grocery store business.

When a firm is experiencing economies of scale, the minimum point of the firm's short-run average total cost curve shifts down as it expands its scale of production.

The slope of the isocost line:

Assume a firm is producing 1000 units of a good by using two inputs, capital and labor, whose per unit prices are $50 and $20.Assume also that the marginal physical product of the last unit of capital is 25 and the marginal physical product of the last unit of labor is 15.In order to minimize its costs of production, the firm should adjust its combination of inputs by employing more labor and less capital.

In which of the following situations would consideration of the minimum efficient scale of operation suggest that the market should be served by a single firm to minimize production costs?

Assume that firms A and B have the same minimum efficient scale of operation and, at current production levels, both firms are incurring the same average costs of production.However, firm A's output is 5 times larger than firm B's output.How is this possible?

Labor resistance can be a major impediment to increased productivity in many firms.

Explain how labor resistance and political and legislative influences reduce the ability of firms to minimize their costs of production.What do the two have in common in this regard?

Empirical evidence suggests that economies of scale, advertising and image differentiation, and risk spreading all help account for the large-scale production that exists in many sectors of the economy.

As the price of labor increases relative to the price of capital, the firm will move to a more labor-intensive production method to minimize costs.

Economies of scale are illustrated by:

According to the text there appear to be very limited opportunities for input substitution in the production of pipe organs.Which of the following is the most plausible explanation for this observation?

If an industry is characterized by substantial diseconomies of scale, as a particular firm in the industry expands its production capacity we will observe:

Studies and experience suggest that labor and capital are highly complementary inputs to the production of pipe organs.

Which of the following would have the least amount of influence on a manager's choice of which inputs to employ in a production process?
