Homo Economicus

Economic Prosperity from the Barrel of a Gun

October 08, 2014

Since September, tens of thousands of pro-democracy protesters have taken to the streets of Hong Kong. The protesters argue that the Chinese Communist Party has broken its legal obligation to hold free elections for the city’s Chief Executive. Beijing’s election proposal would limit candidates to a select few vetted by a committee loyal to the central government, while the protestors clamor for open nominations.

On a per-capita basis, Hong Kong is one of the world’s richest economies; its residents enjoy some of the best health care outcomes in the developed world.

In Defense of High Frequency Trading

April 14, 2014

In his new book “Flash Boys,” Michael Lewis explains how high frequency traders are rigging the American stock market. It was an instantaneous hit; according to Malcolm Gladwell “in the hands of Michael Lewis, anything is possible.” Indeed, Lewis has accomplished the impossible task of mistaking the great financial revolution’s protagonist for its antagonist.
