Legislative lotteries?

Did you know the U.S. House of Representatives uses a lottery to allocate office space to its new members? Why doesn’t the Congress use a lottery system for budget appropriations as well? By way of example, why not (a) set aside a fixed amount of revenues for such things as defense, agricultural subsidies, or social-welfare spending and then (b) allocate monies to specific programs within each category through a lottery? If properly designed, a lottery system of budget appropriations, by inserting a high degree of randomness into the process, could reduce the overall level of legislative rent-seeking behavior.

Spoiler alert: Mr Cusick recommends a market approach to Internet service. (Hat tip to the amazing Tyler Cowen for the pointer; image below courtesy of the Pew Center.)

Legal confidence men

Jane Hu explains in this excellent essay why so-called “scientific jury selection” is not really scientific. But her essay misses the most compelling reason why trial consultants are basically high-priced charlatans: there is no way testing or falsifying their predictions! Karl Popper, anyone?

What would Popper say?

The reference class problem strikes again?

A public interest group based in Las Vegas — the Coalition for the Protection of Marriage — recently filed a petition alleging the non-random assignment of judges in a subset of same-sex marriage cases decided by the Ninth Circuit Court of Appeals in San Francisco. (In federal cases, appeals on the merits are decided by three-judge panels and judges are supposed to be assigned randomly to these panels.) When we first heard of these allegations, we were intrigued by the possibility of “panel packing” or non-randomness in the assignment of judges, since we suspect that the assignment of judges to high-profile cases is anything but random. But, a few days ago, when we finally read the statistical study on which these allegations are based, we detected a possible reference class problem. (For the record, the report was prepared by Dr James H. Matis, a retired statistics professor.)
