Sub part (a):
How many great ideas will occur in the world of 1800.
Sub part (a):
Answer to Problem 20TPS
300 ideas when population is 300 million.
6,000 ideas when population is 6 billion.
Explanation of Solution
The relation between the population size and the number of great ideas is given. It is that only 1 idea out of every one million. Here, the total population is given as 300 million. Thus, by dividing total population with one million, the number of great ideas can be calculated as follows:
Thus, when the population is 300 million, the number of great ideas is 300. When the population is 6 billion, the same can be calculated as follows:
Therefore, when the population is 6 billion, the number of great ideas is 6,000.
Sub part (b):
How many great ideas will occur in the world of 1800 and today.
Sub part (b):
Answer to Problem 20TPS
60 ideas in 1800 and 1,200 great ideas in this year.
Explanation of Solution
The relation between the population size and the number of great ideas is given. It is that only 1 idea out of every one million. Here, the total population is given as 300 million. However, only 20 percent of the population is able to invent new ideas. Thus, by dividing total population with one million, the number of great ideas can be calculated as follows:
Thus, in the year 1800, the number of great ideas is 60. When the population is 6 billion, the same can be calculated as follows:
Therefore, when the population is 6 billion (this year), the number of great ideas is 1,200.
Sub part (c):
How many great ideas will occur in India and China.
Sub part (c):
Answer to Problem 20TPS
1,000 ideas in each country.
Explanation of Solution
The relation between the population size and the number of great ideas is given. It is that only 1 idea out of every one million. The total population by the two countries is 2 billion, which is approximately 1 billion each. Thus, the number of great ideas from each country can be calculated as follows:
Therefore, when the population is 1 billion, the number of great ideas is 1,000. Since both countries have equal population, there will be 1,000 ideas from each.
Sub part (d):
How many great ideas will occur in the world when the population cuts into half this year.
Sub part (d):
Answer to Problem 20TPS
600 ideas in this year.
Explanation of Solution
The relation between the population size and the number of great ideas is given. It is that only 1 idea out of every one million. When the population is 6 billion, only 20 percent of the population invents new ideas. Thus, the number of great ideas can be calculated as follows:
Therefore, when the population is 6 billion (this year), the number of great ideas is 1,200. When the population becomes half, then the number of ideas invented can be calculated as follows:
Thus, when population today becomes half of the 6 billion, the number of great ideas becomes 600.

- 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.)

Samuelson We are now in the "blame phase" of the economic cycle. 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. The reality, I think, is that the economy follows its own Catch-22: By taking prosperity for granted, people perversely subvert prosperity.
