Education as a Signal in Job Market

There may be no market more important to college students than the job market, especially for the students of Class of 2016.  Things were very different a few years back, when my sister graduated in Class of 2008.  According to this Wall Street Journal blog post, 201 employers from the National Association of Colleges and […]

Analyzing Behavior on a personal level

http://nymag.com/scienceofus/2015/11/knowing-how-you-make-decisions-is-important.html Having seen in class how popular consensus and societal pressure shaped people’s decision making, I was intrigued to find this article detailing how individual decision making is analyzed.

Rich Get Richer in Hotel Loyalty Programs

As the hotel giant Marriott buys out the smaller Starwood hotel chain, the benefits of the Starwood Perferred Guest loyalty program will be shifted towards the top elite.
