ECON 需求與供給的問題... [復制鏈接]

一個農夫生產既物件產量升左,佢既總收入都升左(大約係咁)
mc來
a.需求好冇彈性
b.供給好有彈性
其他兩個廢ans唔打
個ans 係a,但係點解呢
兩個ans做出黎既效果都係一樣....
我係度諗緊...

希望有人幫到手

is it because the crops must have an inelastic supply, as the crop will go bad if not sold soon?
and similiarly, food is a necessity for people, so should have an inelastic demand?

b.供給好有彈性
altough there is an elastic supply and increased supply
if the quilibrium point move along the elastic region of demand curve (above the mid-point of demand curve)
the total revenue of sales will be decreased
so ans B is wrong and A is correct

supply 升, Price decrease, output/quantity sold increase

只有(price elascity of demand) Ed > 1 才會total revenue increase

Ed>1, % change in price 細過% change in quantity demanded

total revenve decrease by price 細過total revenve increase by quantity

需求好有彈性

劃個demand-supply diagram就大概可以了解到a & b有唔同（意思）∼

(a) 是對的
