We extend the Berry, Levinsohn and Pakes (BLP, 1995) random coefficients discretechoice demand model, which underlies much recent empirical work in IO. We add interactive fixed effects in the form of a factor structure on the unobserved product characteristics. The interactive fixed effects can be arbitrarily correlated with the observed product characteristics (including price), which accommod...

Password-Authenticated Key Exchange (PAKE) protocols allow parties to share secret keys in an authentic manner based on an easily memorizable password. Recently, Nam et al. showed that a provably secure three-party passwordbased authenticated key exchange protocol using Weil pairing by Wen et al. is vulnerable to a man-in-the-middle attack. In doing so, Nam et al. showed the flaws in the proof ...

This paper empirically studies U.S. and Canadian asbestos mining firms’ divestment process when the asbestos industry faced a long-run decline in demand. I develop a dynamic oligopoly model of capacity adjustment and exit based on Ericson and Pakes (1995). I calibrate my model to a panel data of the U.S. and Canadian asbestos mining industry’s capacities and exit/stay status over 1968-2002, and...
