這三本經濟學小說，印象最深刻的橋段：單價低的產品價格波動大，單價高的產品價格波動小。

譬如30元的平價飲料在柑仔店、超商、全聯、大賣場，價格差距常常會超過兩成，若是3萬元的高價飲料，價格差距足夠吸引人去做功課，尋找便宜的管道入手。

同樣的道理應用在於投資上，也是非常有感覺的，隨便聽明牌買1張，漲十倍、賠光會有差別嗎？歐應投資股票你又會做多少功課呢？炒個千萬房地產你又會做多少功課呢？

等我再來複習一下書本中的文字，再來分享怎麼呼應我的投資心得。

［一戴一露］鞋可以單邊買，因為有人有細腳。幾時到胸圍？

話時話，呢排記得keep 住like and share，主動入嚟睇，同埋設定做see first．真係搵食艱難。但感激大家

1. 小故事，可能有人聽過。甘地坐火車，跌咗一隻鞋落路軌，執唔返。結果佢就快手除埋另一隻鞋，掉埋落路軌。寓意好明顯：與其攬炒，不如益人。對方執到一隻鞋冇用，佢自己留住一隻鞋又冇用　—但佢掉埋另一隻，執到嗰個有一對，就會有用

2. 然後又講返Econ 101，substitutes and complements，同一款對鞋嘅左邊鞋同右邊鞋，就係perfect complements, 個”indifference curve”，一個個L字咁。用人話，就係度個Utility．一隻左一隻右，很好。三隻左三隻右，更好。但三隻左一隻右，同一隻左一隻右，應該係一樣嘅　（當然，你拎去炒就可能唔同，Lets say 米高佐敦最後一場著過嘅鞋，左邊畀人整唔見咗，得返右邊，都有得炒的）

3. 不過，又要改寫了。而家，買鞋就可以單丁咁買！其實好多年前已經有人提出過，但當然冇乜人真係大規模做。而家電商Zappos就可以畀你買一隻鞋。介紹返，間公司而家係萬惡嘅Amazon的

4. 點解要賣單邊鞋？倒唔係因為有人漏低一隻在路軌。

5. 首先係有人截肢，冇咗一隻腳（＊），呢個「市場」幾大，但一路冇人理。

6. 另外亦都因為，其實好多人都係大細腳（其實我都係），左右腳唔同碼嘅。而家亦可以畀你買左右邊唔同碼。

7. 認真，其實胸圍都應該有得咁玩吧？正如大細眼好平常，兩邊胸一大一細都好常見，但好似冇乜人理呢個問題。真係藍海呀！寫個proposal 去呃 funding啦。You heard it first from Ivan

（＊）六字故事：Sorry soldier. shoes sold in pairs。另一玩法就係For sale: baby shoes, never worn。中文呢？「她含了他的它」。

📍防疫第四招：寫一封英文信

Dear Dr. Tedros Adhanom Ghebreyesus,

Have you ever visited Taiwan? It is a small island right next to China that has an area of 35,808 square kilometers with 23.6 million inhabitants. YES. We have our own constitution, our own government and our democratically elected leaders. We are a sovereign state.

And YES. Taiwan is a developed country. Although Taiwan has been excluded and blocked or barred from many international organizations and communities due to China’s interference and suppression, Taiwan still managed to have the best healthcare system and advanced medical technologies among the best in the world.

Do you still remember? In the end of 2019, it was Taiwan that warned WHO and China about possible human-to-human transmission of the new coronavirus, but Chinese authorities silenced doctors and refused to admit. Then what have you done?

You did not make it public! You tolerated China’s lack of transparency and decided to be their accomplice in making the coronavirus pandemic a global catastrophe.

You deliberately put people’s health at risk, and now the whole world suffers from China’s initial denials, continuous cover-ups and your inability. Unfortunately, COVID-19 had 91,595 deaths by today. How much more to come?

_

No one judges you because of your race or skin color, nor hairstyle nor gender, but your dereliction of duty! And, hey, those judgments and complaints actually come from not only Asia, not just Europe, but all over the world!

You have always treated Taiwan’s absence in WHO with indifference. Like a wicked ally of China. And when this whole coronavirus gone wild, you continued to refuse all the kind warnings and messages from Taiwan. We’re always here, and we’re willing to help.

How dare you accuse Taiwan of these unfounded allegations when you’ve always been the person with power who keeps discriminating and trampling Taiwan and Taiwanese people the whole time?

In Taiwan, we value human rights, liberty and equality. We are always described kind and friendly. Yet facing injustice, on no account must we endure. We strongly oppose your malicious smear and bullying. We demand a public apology from you to Taiwan and Taiwanese people.

彈到屎 / 動詞 介詞 名詞 /

n. 台語念比較傳神

有時候當一個人太邪惡（比如希特勒）或太可惡（比如毛澤東），我們不會有機會歧視他；我們只能無視他，然後想辦法讓自己更強大。

有點孤單，但非常堅強。

但還是難免，彈到屎。

昨天氣到決定寫一封英文信，結果寫到大半夜可惡。好久沒寫英文作文，好生疏喔天啊😂 我只想做個好國民，但當個好國民有點累🙄

😎特別說明：據說有些人的FB會自動把我的英文信翻譯成中文，記得把功能關掉才能看到英文原文～

我的中文不可能寫得那麼不流暢好嗎😎
