外母在家收拾時找到這些陳年舊物,現在的同學應該不知道這些是甚麼來的吧?
My students these days probably don’t know what these are.

「請早夜特替紅減100」這句如果要以英文表達要用多少個字?
“Hiring [for] morning, evening, overnight [and] substitute [shifts], 100 [dollars] off [on] red.”* That’s how many words you need to translate that phrase printed on the left of this taxi.

* ‘Red’ represents public holidays, because the latter are marked in red on calendars.

在經濟系一年級的數學課中,set是其中一個比較難解釋有何用處的課題,因為本科經濟學課程基本上用不著。我為今年的第一份功課思前想後,最後嘗試用一個統計陷阱來作為例子。
It is not easy to explain what is the use of sets to first-year economics majors since it is rarely used in the undergraduate economics curriculum. I ended up using a statistical paradox in the first assignment.

我在某間大型保險公司選購定期人壽保險時發現一個有趣現象:增加保額的邊際差價原來可以時上時落,最高和最低相差超過一倍。最特別是買300萬保額竟然比買250萬便宜!

如果這現象背後是有著精算的考慮,那會是因為300萬的人有著過人之處?還是受到某些政策的影響?

While I am shopping for term life insurance I have discovered that pricing can be non-monotonic. In the case illustrated below, the price of getting 3 million coverage is actually lower than that of 2.5 million. What is the actuarial logic behind this phenomenon?

個人一小步,社會一大步: 今次隨中文大學研究院去馬來西亞招生, 只要吸引到一個學生來中大經濟系, 就已經可以增加馬來西亞學生人數超過100%! #尋找他鄉的學生
