  1. By: Chi, Feng; Yang, Nathan
    Abstract: The paper provides some support in favor of Twitter adoption being driven by outreach reasons, rather than the well-popularized transparency motive. Furthermore, outreach considerations factor into a Republican's perceived benefit more than a Democrat's.
    Keywords: Government communication; diffusion of technology; political marketing; social media.

    Abstract: OECD labor markets have become more "polarized" with employment in the middle of theskill distribution falling relative to the top and (in recent years) also the bottom of the skilldistribution. We test the hypothesis of Autor, Levy, and Murnane (2003) that this is partlydue to information and communication technologies (ICT) complementing the analyticaltasks primarily performed by highly educated workers and substituting for routine tasksgenerally performed by middle educated workers (with little effect on low educated workersperforming manual non-routine tasks). Using industry level data on the US, Japan, and nineEuropean countries 1980-2004 we find evidence consistent with ICT-based polarization.Industries with faster growth of ICT had greater increases in relative demand for higheducated workers and bigger falls in relative demand for middle educated workers. Tradeopenness is also associated with polarization, but this is not robust to controls for technology(like R&D). Technologies can account for up to a quarter of the growth in demand for thecollege educated in the quarter century since 1980.
    Keywords: Technology, trade, skill demand, wage inequality

    Abstract: The network literature commonly neglects the importance of a clear distinction between interactions and information exchanges. Although convenient, this oversight is not innocuous and may lead to erroneous conclusions when looking at mechanisms such as contagion processes. We use simulation methods and conduct a systematic analysis of the implications of such omission. We show that the lack of distinction between information and interaction structures is not without consequences. More precisely, when agents use a myopic best response, only information exchanges matter and interactions can be ignored. With imitation however, both information and interactions play important yet different roles in contagion.
    Keywords: contagion, networks, coordination games, scale-free, small-worlds, best response, imitation
