Jones owns a barber shop and charges $6 per haircut. By hiring one barber at $10 per hour the shop can provide 24 haircuts per 8 hour day. By taking a second barber at the same wage rate the shop can no provide a total of 42 haircuts per day. The MRP of the second barber is

$108

a profit maximizing firm employs resources to the point where

MRP = MRC

Inverted U theory

R&D expenditures first arise as a percentage of firms' sales as industry concentration increases, but then fall as higher industry concentration occurs

Resource pricing is important because

1. resource prices are a major determinant of money incomes. 2. resource prices allocate scarce resources among alternative uses. 3. resource prices, along with resource productivity, are important to firms in minimizing their costs.

barriers to entry are either weak or nonexistent

Entrepreneurship

can be carried out either by individuals or teams of individuals

broadly defined, technological advance

comprises new and improved goods and services and new and improved ways of producing or distributing them

the demand for labor is derived from

consumer demand for the product or service it is helping to produce

in the United States professional football players can earn much higher incomes than professional soccer players. this occurs because

consumers have a greater demand for football games than for soccer games

d. subway sandwiches

Other things equal, an increase in the equilibrium interest rate will

decrease purchases of capital goods and reduce R&D spending

Suppose an oligopolistic producer assumes its rivals will ignore a price increase but match a price cut. In this case the firm perceives its:

demand curve is kinked, being steeper below the going price than above

as pizza is topped with BBQ chicken became popular at speciality restaurants, Pizza Hut introduced a similar pizza. this imitation illustrates

diffusion

the corporate decision on type and level of R&D activity is difficult because

expected returns lie in the future and are highly uncertain

the marginal benefit to a firm from its R&D expenditures is depicted by its

expected-rate-of-return curve

technological advance improves allocative efficiency by

giving society a more preferred mix of goods and services

If you sum the squares of the market shares of each firm in an industry (as measured by percent of industry sales), you are calculating the:

herfindahi index

to say that land rent preforms no incentive function means that

higher rental payments will not bring forth a larger quantity of land

the copper, aluminum, cement, and industrial alcohol industries are examples of

homogeneous oligopoly

process innovation refers to

implementation of better methods of producing products

inclusive unionism

the first commercial introduction, as opposed to first discovery, of transparent tape is an example of

technological advance is a three-step process involving

invention, innovation, and diffusion.

the modern view of technological advance is that it

is an internal element of capitalism, occurring in responses to profit incentives

as it relates to the R&D decision, the interest-rate-cost-of-funds curve:

is the marginal cost element in the MB = MC decision framework

Henry George advocated a single tax on:

land

the monopolistically competitive seller's demand curve will become more elastic the

larger the number of competitors

technological advance improves productive efficiency by

lowering average total cost

monopolistic competition means

many firms producing differentiated products

marginal revenue product of the second worker is $20

the economic term for a sole employer in a nonunion community is

monopolist

economic profit is most closely associated with

monopoly, innovation, and uninsurable risks

When a monopolistically competitive firm is in long-run equilibrium:

mr = mc and p > minimum atc

we would expect a cartel to achieve

neither allocative efficiency nor productive efficiency.

economic analysis of a monopolistically competitive industry is more complicated than that of pure competition because

of product differentiation and consequent product promotion activities

the market supply curve for labor is upsloping because

of the opportunity cost of labor in housekeeping, leisure, or alternative employments

the conclusion that oligopoly is inefficient relative to the competitive ideal must be qualified because

overtime oligopolistic industries may promote more rapid product development and greater improvement of production techniques than if they were purely competitive

Kodak introduced to the marketplace a digital camera which uses no film, but takes photos that can be shown on personal computers. This is an example of:

product innovation

in a oligopolistic market

products may be standardized or differentiated

reduces the number of workers it employs so that it can pay each worker a lower wage rate

Pure or economic profit is:

the amount by which total revenue exceeds total costs

the marginal revenue product schedule is
