Skip to search - Accesskey = s. Random thoughts of an economist. Does it look suspicious to you? By kafuwong on October 9, 2014. A friend sent me a striking table of actuarial study of life span vs. age at retirement . The table shows a person who retires at age 49.9 will die at 86 on average, and a person who retires at age 65.2 will live to 66.8 on average. The data suggests that I should consider retiring early. A person who retires at age 65.2 will live to 66.8 on average? I think it is because most ...

Beside the extreme of white and black, there is a spectrum of grey. Given a color of grey, some might conclude it as black and some white. It depends on the referenced color. When grey is put next to white, it looks like black. When grey is put next to black, it looks like white. How can I know that the color I was is likely grey? The views of others are so important!

Skip to search - Accesskey = s. Random thoughts of an economist. Historic preservation is other people’s job. By kafuwong on May 17, 2014. A historic building near my workplace was being demolished to make room for a residential high rise. Some of my friends were annoyed by such development. They wanted the century old building to be preserved. People’s behavior is predictably rational! Let the government buy out the property! We tend to say we are willing to pay a lot to see the preservation. Like many ...

I’m finally meeting with a lawyer to draw up a will. If you were thinking of doing something extra nice for me, now would be a good time. I enjoyed so much reading how his friends replied. Of course, there is no point of summarizing their replies. But, I thought you might be interested in what I said to him. Follow “R...

A friend was trying to redeem his cake coupon from a chain bakery. His coupon was two days from expiry. If he had not done it in time, the chain bakery will gain. Hm… What is the redemption rate of cake coupons? That is, how much do the chain bakery gain per year due to people’s failure to redeem their coupons? Now, how do we get an estimate of the redemption rate? You a...

And, the statement came from a consultant of the “Hong Kong Poison Control Network”. In fact, at least supposedly so, nowadays even the paint cover of pencils should not contain lead so that most pencils are safe for chewing (not encouraged).
