price. And the people who want no-frills service and cheap product will also get it at the other end of the market. So competition allows a range of variety to occur in a market. The benefit to society of competition is that it makes a major contribution to the fundamental economic issue, which is the scarcity of productive resources. It means that on the production side, there is maximum pressure to conserve the use of those scarce productive resources. On the demand side it also rations consumer demand appropriately, and it also tends to mean that the variety of consumer needs can be met.

(2)你认为这一价格控制政策是否对所有的学生都是有利的？为什么是或为什么不是？

The city council of a small college town decides to regulate rents in order to reduce student living expenses. Suppose the average annual market - clearing rent for a two - bedroom apartment had been $ 700 per month and that rents were expected to increase to $ 900 within a year. The city council limits rents to their current S 700 - per - month level.

a. Draw a supply and demand graph to illustrate what will happen to the rental price of an apartment after the imposition of rent controls.

b. Do you think this policy will benefit all students？ Why or why not？

dings is a phenomenon known as the first-night effect. If a person stays in the same room the following night they tend to sleep more soundly. Yuka Sasaki and her colleagues at Brown University set out to investigate the origins of this effect.

Dr. Sasaki knew the first-night effect probably has something to do with how humans evolved. The puzzle was what benefit would be gained from it when performance might be affected the following day. She also knew from previous work conducted on birds and dolphins that these animals put half of their brains to sleep at a time so that they can rest while remaining alert enough to avoid predators (捕食者). This led her to wonder if people might be doing the same thing. To take a closer look, her team studied 35 healthy people as they slept in the unfamiliar environment of the universitys Department of Psychological Sciences. The participants each slept in the department for two nights and were carefully monitored with techniques that looked at the activity of their brains. Dr. Sasaki found, as expected, the participants slept less well on their first night than they did on their second, taking more than twice as long to fall asleep and sleeping less overall. During deep sleep, the participants’ brains behaved in a similar manner seen in birds and dolphins. On the first night only, the left hemispheres (半球、of their brains did not sleep nearly as deeply as their right hemispheres did.

Curious if the left hemispheres were indeed remaining awake to process information detected in the surrounding environment, Dr. Sasaki re-ran the experiment while presenting the sleeping participants with a mix of regularly timed beeps (蜂鸣声、of the same tone and irregular beeps of a different tone during the night. She worked out that, if the left hemisphere was staying alert to keep guard in a strange environment, then it would react to the irregular beeps by stirring people from sleep and would ignore the regularly timed ones. This is precisely what she found.
