一個賽局觀念 - 經濟

剛剛在念課本，在auction章節時，

看到最後面有一句結論不是很懂，

" Truth telling is a weakly dominant strategy in second price auction,

but not in first auction. "

在secon-price的部分，課本的解釋是：

in a second-price sealed-bid auction (with perfect information), a player's

bid equal to her valuation weakly dominates all her other bids.

但看完我還是不太懂，可以請了解的人替我解惑一下嗎?

謝謝ˊˋ
