Chapter 2.A, Problem 9P
To determine
The relationship between two variables
Concept Introduction:
Dependent Variable: The variables, which are tested in the economic model, is termed as dependent variable.
Independent Variable: The variation of the particular variable is measured on the dependent variable is referred as independent variable.
Slope of Curve: The steepness of a line is measured by slope of a curve, it states about the change in value of Y variable per unit of X variable.

If Firms A, B and C are in the same industry, is this industry in long-run equilibrium?
○ A. Yes, because P = MC = MR for each of the 3 firms.
○ B. No, because Firm A is not producing at a profit-maximizing level of output.
○ C. Yes, because all 3 firms are producing at their minimum average total cost.
OD. The answer is uncertain since it's unknown whether the firms are producing at the minimum efficient scale or not.
○ E. No, because if the industry were in equilibrium, all 3 firms would be earning zero economic profits.
Consider the table on the right, which shows the various
revenue concepts for a perfectly competitive firm.
Suppose the firm faces a constant market price of $4.
Compute first total revenue for each level of output and fill
in the TR column of the table. Next, compute marginal
revenue for each level of output and fill in the MR column
of the table.
(Marginal revenue at each level of output is computed
using total revenue for two successive levels of output.
For example, marginal revenue at 160 uses total revenue
for output levels 120 and 160.)

As the housing slump deepens and financial markets swing erratically, we've embarked on the usual search for culprits. Who got us into this mess? Our investigations will doubtlessly reveal, as they already have, much wishful thinking and miscalculation. They will also find incompetence, predatory behavior and probably some criminality. But let me suggest that, though inevitable and necessary, this exercise is also simplistic and deceptive. -- business It assumes that, absent mistakes and misdeeds, we might remain in a permanent paradise of powerful income and wealth growth.
