Companies With Benefits or Potential Welfare Losses of Benefits

Many companies offer employees ‘benefits.’ These include paying for healthcare, investment plans, company gym, luncheons etc. (Just ask a Silicon Valley tech. employee for the full list.)

Beyond Anomaly Detection: Supervised Learning from `Bad' Transactions

Nearly every time you connect to the Internet, multiple servers log a bunch of details about the request.

Ideally, we would like to be able to place ideology of each bit of information consumed in relation to the ideological location of the person. And we would like a time-stamped distribution of the bits consumed. We can then summarize various moments of that distribution (or the distribution of ideological

Reviewing the Peer Review
