学ECON的,帮我看到题

[darkforce]

Suppose the government regulates the prices of beef and chicken and sets them below their market-clearing levels.

What will happen to the price of pork? Explain briefly.

晕,我以为PRICE会DECREASE...但是...

还有
(b) (2 marks)
Suppose the agency bows to the wishes of the board and sets a rental of $900 per month on all apartments to allow landlords a “fair” rate of return. If 50 percent of any long-run increases in apartment offerings come from new construction, how many apartments are constructed?

QS = 70 + 7*9 （new price）
= 133

QS = 70 + 7*6 (market-clearing price)
= 112

New construction = (133 ? 112)*0.5
= 10.5 tens of thousands of apartment
Therefore 10.5 tens of thousands of apartments are constructed.

对吗?

我也绝的是,但是LONG TERM也是下降吗?

 

[月舞花魂]

因为我感觉牛肉，鸡肉和猪肉都是差不多的东西，如果两样东西降了的话，猪肉也应该降啊，不然卖不出去的呀

 

[darkforce]

但是如果从LONG RUN来看的话, THERE IS A SHORTAGE OF BEEF AND CHICKEND BUT THE GOVERNMENT HAS SET THE PRICE BELOW THE MARKET CLEARING PRICE SO THE THEORY IS THAT THE QUANTITY SUPPLIED SHOULD INCREASE BUT WILL FARMERS INCREASE THE SUPPLY SINCE THE PRICE IS LOW?

你这是宏观还是微观啊？应该是宏观吧

其实经济最好学了，只要看书，基本上都能动的

ls的莫非就是学经济的

所有的人都去买牛肉鸡肉..买牛肉的人会少...所以PRICE DECREASE?

恩，我刚才说错了，GOVENMENT定的价格不会改变，beef,chicken和pork是substution,大家都会因为beef和chicken的价格低而不去买pork,最后导致pork的价格也会降低

恩恩~但是beef and chicken has a limited supply但供应不够的时候人们会去买猪肉,那猪肉的价格会上升,可是如果beef and chicken的供应不够的话, under normal market conditon会有人提供供应的然后就reach equalibrium.
but the government has set a price below the market price, the question is will the producers provide more chicken and beef if they are not making a profit?
晕,不知道问的清楚不.
