➤ Why is charging $1,450 for the first two units and $1,225 for additional units second-degree pricing?
That schedule varies price by quantity blocks rather than by buyer identity. It is second-degree price discrimination because customers self-select into quantity tiers, revealing valuation. This block pricing or quantity-discount approach helps extract surplus when marginal willingness to pay falls with additional units and when seller cannot perfectly price by individual.

Back in 2015, the Fireflies installed a chemical filtration unit in a secured quarantine zone to purify contaminated water for survivors. The unit cost $500,000 and had a processing capacity of 1,000 liters per hour — barely enough to keep the population alive during the fungal outbreak. Now, in 2025, with more survivors arriving and fungal spores worsening in concentration, the Fireflies plan to upgrade to a larger unit with a capacity of 2,000 liters per hour. Due to economic instability and scarce resources, the Chemical Engineering Cost Index (CECI) has risen from 575 in 2015 to 750 in 2025. Ellie, tasked with supply coordination, finds old FEDRA records showing that the power sizing exponent for this type of equipment is 0.6. Survivor’s Task: Using the power sizing model and cost index adjustment, estimate the cost of the new filtration unit in 2025. Your analysis could determine whether this upgrade is feasible — or fatal.

Why are smaller automobile engines more common in Europe than in the United States? multiple choice 1
Because European speed limits are generally lower than those in the United States.
Because smaller European cars don’t have room for larger engines.
Because manual transmissions, which are more common in Europe, don’t require as much engine power to achieve acceptable performance.
Because gasoline is taxed more heavily in Europe than in the United States.

➤ What supports the claim about lower prices for older baseball cards of Black players?
Researchers used historical sales and hedonic pricing models to compare card values while controlling for player quality, era, and rarity. They found modest price penalties for cards showing Black players, consistent with racial bias among collectors. The result emerges from market data and regression analysis rather than simple anecdote or single sales.

In a congressional district somewhere in the U.S., a new representative is being elected. The voters all have one-dimensional political views that can be neatly arrayed on a left-right spectrum. We can define the ”location” of a citizen’s political views in the following way. The citizen with the most extreme left-wing views is said to be at point 0 and the citizen with the most extreme right-wing views is said to be at point 1. If a citizen has views that are to the right of the views of the fraction x of the state’s population, that citizen’s views are said to be located at point x. There are two candidates for the congressional seat and they are forced to publicly state their own political position simultaneously on the zero-one left-right scale. 1.a (2 points) Suppose voters always vote for the candidate whose stated position is nearest to their own views and suppose each candidate cares only about getting as many votes as possible.

The stock of money people hold to take advantage of future changes in the prices of financial assets other than money
The stock of money people hold to pay unpredictable expenses
The stock of money people hold to pay everyday predictable expenses
Complete the following statement about the relationship between the interest rate and speculative balances.
As the interest rate falls, the opportunity cost of holding money , and people their speculative balances.
Identify the motive for holding money in the following scenario.
Tim recently moved from a commission-based sales job in which his income fluctuated somewhat unpredictably from one month to the next to a salary-based management position where he receives a fixed paycheck each month. His newfound income stability causes him to lower the amount of money he keeps in a savings account to guard against a sudden drop in income. This is an example of a decrease in Tim’s demand for money.

As with current university pricing schemes, proponents of full-cost pricing generally argue for a standard fee (albeit higher than at present) for all students. Standard-fee proposals ignore relative cost and demand differences among activities in the university.
Discuss several possible rationales for charging different prices for different courses of study.
What are the income-distribution effects of a pricing scheme that charges the same fee to all students?
If universities adopted a system of full-cost (or marginal cost) pricing for various courses, what would you expect the impact on the efficiency of resource allocations within the university to be?
Would you complain less about large lecture sections taught by graduate students if these were priced significantly lower than small seminars taught by outstanding scholars?
What problems could you see arising from a university that adopted such a pricing scheme?
