試評論及分析價值之謎，根據經濟學

很遺憾沒有太多人評論

因為我以前見過市場論者，以供需求來決定，能使經濟極有效率進行，其中一論點是張五常的制度費用論，及香港的自由市場成功。但反論者如社會主義者害怕資本家的過度利益，造成壟斷行為，集合加價或減價以達到自己的利益，但沒有人進行此評論，實在遺憾

Since my chinese is not good, wish you don't mind.

Firstly, invisible hand is a concept that market will reflect the best presenting value by Demand Vs Supply.... etc. (In chinese is 小政府 大市場) However, the value may be affected by expectation, government...etc. For example, if you expect that the economic environment will become worst, then you will save up your money and decrease the expenditure. If everyone does it, then the good value will be affected. Also another example, OPEC control the gasoline production to increase price. Those cause the market in unbalance. ( 市場失效又如何?有人認為人的自私及恐懼或貪婪令市場失效 )
For increase government expenditure has been most commonly used on changing economic environment. Since the increased expenditure will increase willing on spending.
自由市場如佛利民等支持少干預，等市場自由運作，反映現值的意思指，市場有效率，人們在理智判斷下，價值價隨未來的變化而變，
For this speech is based on theory, but refer to public finance topic. Government plays important role on deflation period.

I am not professional, wish it can help

首先要更正既係
Invisible hand 唔係「後經濟學者」 「判斷」出黎
而係 Adam Smith 用既一個比喻

因為無形的手只係比喻, 所以根本唔可能反映任何價值

希望你可以解釋一下你所指既「現值」同「市場失效」
等我睇下可唔可以進一步解答你既問題
因為中文同英文字義可能唔同我唔想講錯..

理論上無之手係可以反映出一件物件的最佳價值, 情況就好似拍賣一樣, 經過一輪競爭之後, 價高者得。該物件會以一個最佳的價格成交。

但先決的條件係該物件是有一個精晰的產權(擁有權), 咁個物主先至可以攞出來賣。如果個件物品都唔知係邊個既(無一個精晰的產權(擁有權)), 等於無人可以攞出來賣, 無賣家, 就等於無價錢, 但個件物品是有價值的。
