The WINE conference started today, after a day’s tutorial we had a reception - on a yacht on Pudong river, around the Bund. It is by far the fanciest academic event I’ve ever attended. Salute to the organization comittee! Here’s a really impressive occasion I’ve witnessed tonight. Herve Moulin is scheduled on giving the opening keynote talk tmrw morning, and he was on the yacht tonight as well. He was alone for sometime so I went for some casual chatting with this charmingly witted scholar....

Here’s a recap of yesterday’s keynote tutorial given by prof. Saif Benjaafar, based on his MSOM review paper Operations Management in the Age of the Sharing Economy: What Is Old and What Is New?. The paper described three “canonical” applications that have garnered much attention from the operations management community, and used these applications to highlight distinguishing features of sharing economy business models and to point out research questions that are new....

Our paper got second place in the data competition. Coolness.

So it’s an art picking out talks to attend out of all the parellel tracks - after all, why can’t the organizer just pick out a smaller amount of paper and make everyone’s life easier?

In the bias and wisdom in decision making course that I’ve taken this semester, we featured the topic intertemperal choice today. It’s pretty cliché a topic that, well, usually everything starts with this function: $$ U(\mathbf x) = u(x_0) + \beta\sum_{t = 1}^\infty\sigma^t u(x_t). $$ But something interesting came up today. It’s called the growth curve. Consider choosing from various ways of growing over time - some trajectory is log-like while others can be exponential-like....
