Worry over polarization has grown alongside the digital information consump-tion revolution. Where most scientific work considered user-generated and user-disseminated (i.e., Web 2.0) content as the culprit, the potential of purely increased access to informa-tion (or Web 1.0) has been largely...

How does trading in one venue affect the quoting strategies of market makers in other venues? We develop a two-venue imperfect competition model in which market makers face quadratic costs when absorbing shocks. Nonconstant marginal costs imply that absorbing a shock in one venue simultaneously...

We estimate the impact of temperature extremes on mortality in Vietnam, using daily data on temperatures and monthly data on mortality during the 2000-2018 period. We find that both cold and heat waves cause higher mortality, particularly among older people and those living in the hot regions in...

We study allocative efficiency and optimal regulation in inefficient economies with misalloca-tion and pecuniary externalities. We characterize the allocative value of a market based on its price, cross-sectional misallocation among participants, and pecuniary externalities. With both complete and...

We present a theory of conglomerate mergers and explore the effect of portfolio differentiation due to the heterogeneity of consumption synergy derived from product bundling. The differentiation of product portfolios reduces competition and leads to higher prices for stand- alone products in highly...

This paper applies an experimental design developed by Bleichrodt et al. (2010) to test the key assumption of original regret theory (Loomes and Sugden, 1982): convexity of the regret function. We elicit preferences for financial and health outcomes for about 1,000 subjects, yielding some evidence...
