Multicollinearity is the issue when explanatory variables in a regression are not independent of one another. When I was taught applied econometrics, I was told that I should not worry about multi-collinearity because the problem is very rare, and if it was the result of a misspecification, then my software would warn me about it.… Continue reading Multicollinearity and social risks: A problem in the Journal of Risk and Uncertainty and my solution
I have a new working paper with Alisa Frik about privacy risk. I forgot to write about it here up to now, but here it goes: Privacy protection, risk attitudes, and the need for control: An experimental study. In that paper, we report results of an experiment where we exposed subjects to the risk of… Continue reading Privacy protection, risk attitudes, and the need for control

Privacy, Trust and Social Network Formation Alexia Gaudeul and Caterina Giannetti CEGE… Continue reading New paper on privacy and social network formation

This is actually a nice illustration of an issue with nudges, how they… Continue reading The battle of the Nudge
Paolo Crosetto writes about our new paper about price and format competition with consumer confusion. http://paolocrosetto.wordpress.com/2014/11/07/price-and-format-competition-with-consumer-confusion-a-new-paper-with-alexia-gaudeul/ Nice graphs depict our “Chrome market model”: Our conclusion is as follows: In a nutshell, clever consumers are not enough to avoid collusion and high prices. Consumer protection may therefore require some encouragement for firms to present prices and… Continue reading Price and format competition with consumer confusion
A very busy summer for me this year, after last year’s ban on conferences to focus on doing experiments. For me the summer started at the end of May with a research stay in Rennes, where I was invited by Eric Darmon and gave a talk about my research with Paolo Crosetto on how firms… Continue reading Busy like a bee and still buzzing not so weakly
