幫幫忙 請問幾個經濟學名詞

補習班老師曾說,
他非常喜歡大家寫信問他問題,
但在提問時,先把自己的看法或所得的資料寫出來,
老師在針對問題的盲點回答,
他最討厭而且絕對不回答的問題類型如同:
何謂"邊際效益"?...這種簡單的定義型問題.

自己都不先多寫點內容(或先查閱資料),就想投機地一次想獲得解答?

其實我是個英語系的學生,從未碰過有關於經濟方面的問題. 只是口譯老師最近要我們翻譯一篇文章,所以才問大家的. 而且在問之前,我已經上網查過了,都只有中英翻譯,並沒有解釋. 那可否請大家提供何處可找到這些資料.(我已經查一天了)謝謝!

Cost minimization is when isoquant curve is just tangent to the isocost line...

Corner solutions happens when the total income is spent on one good.

When the budge line moves and become the same line as the indifference curve, the consumer can choose any point on the line to consume...

And the cross elasticity could be 0, great than 0 (subsitutes)and less than 0 (completements)

Hope this hlep...
