While studying how to legally save on taxes, I realized the following trick.
This procedure completely avoids capital gains tax (15% at my tax bracket). The reason is that the standard deduction for a child is $1,350, so as long as income is below that amount, there is no need to file or pay taxes.
I wish I had known about this trick earlier, but it’s better to learn about it later than never. As I have substantial shares of VTI that I bought in 2010 for $60 per share but now are valued at around $335, I transferred a few shares to my kids’ UTMA accounts and sold them. Turning appreciated stocks into cash is almost alchemy.

I often fly bewteen San Diego and Atlanta, usually with Delta (because there are more flight options than Alaska, which also offers direct flights between SAN and ATL). As I was looking to book my next trips, I noticed that flight tickets got much more expensive, often over $600 round trip with Delta (main cabin). After playing around with various searches, I realized that if I book a round trip from Atlanta instead of from San Diego, the price drops by 25% or more. I am not sure why, but maybe it’s because if I book from Atlanta, the trip is over the weekend, so the booking system may judge myself as a (price-sensitive) leisure traveller. By using Alaska instead of Delta, the price often drops below $300 round trip. Although I have achieved gold status with Delta, since Alaska is much cheaper and also offers status match, I will likely switch.

Great news. Starting from the September 2025 issue, Econ Journal Watch publishes papers typeset in LaTeX.
For years, I have been begging the editorial board of EJW to accept LaTeX submissions. This summer, I attempted to submit a comment to urge EJW to accept LaTeX submissions, but to my surprise, I was told EJW was working to transition to LaTeX over the summer, so the point of my comment became moot. The call for papers does not seem to be updated yet, but we will see whether they will officially announce that they welcome LaTeX submissions.

American Express increased the annual fee of Platinum Card from $695 to $895.
In this post last year, I discussed my love-hate relationship with the American Express Platinum Card. When I opened the account many years ago, I recall that the annual fee was $450. Then it increased to $550 and then to $695. Now it’s $895. It has increased to the point that I need to reconsider whether it is worth keeping the card. (See also this opinion.)
The card provides various credits, but most of them are things that I won’t use or are redundant.
I didn’t list all the benefits and credits, but the rest are less important. My membership renewal is next May, so I still have time to think about it.
