      Chain Stability in Trading Networks

      By: John William Hatfield, Scott Duke Kominers, Alexandru Nichifor, Michael Ostrovsky and Alexander Westkamp
      We show that in general trading networks with bilateral contracts, a suitably adapted chain stability concept (Ostrovsky, 2008) is equivalent to stability (Hatfield and Kominers, 2012; Hatfield et al., 2013) if all agents' preferences are fully substitutable and...  View Details

      Lone Wolves in Competitive Equilibria

      By: Ravi Jagadeesan, Scott Duke Kominers and Ross Rheingans-Yoo
      This paper develops a class of equilibrium-independent predictions of competitive equilibrium with indivisibilities. Specifically, we prove an analogue of the “Lone Wolf Theorem” of classical matching theory, showing that when utility is perfectly transferable, any...  View Details

      Deposit Competition and Financial Fragility: Evidence from the U.S. Banking Sector

      By: Mark Egan, Ali Hortaçsu and Gregor Matvos
      We develop a structural empirical model of the US banking sector. Insured depositors and run-prone uninsured depositors choose between differentiated banks. Banks compete for deposits and endogenously default. The estimated demand for uninsured deposits declines with...  View Details

      Multilateral Matching

      By: John William Hatfield and Scott Duke Kominers
      We introduce a matching model in which agents engage in joint ventures via multilateral contracts. This approach allows us to consider production complementarities previously outside the scope of matching theory. We show analogues of the first and second welfare...  View Details

      Stability and Competitive Equilibrium in Trading Networks

      By: John William Hatfield, Scott Duke Kominers, Alexandru Nichifor, Michael Ostrovsky and Alexander Westkamp
      We introduce a model in which agents in a network can trade via bilateral contracts. We find that when continuous transfers are allowed and utilities are quasi-linear, the full substitutability of preferences is sufficient to guarantee the existence of stable outcomes...  View Details

      Anger and Regulation

      By: Rafael Di Tella and Juan Dubra
      We propose a model where voters experience an emotional cost when they observe a firm that has displayed insufficient concern for other people's welfare (altruism) in the process of making high profits. Even with few truly altruistic firms, an equilibrium may emerge...  View Details

      Katz and Shapiro (1985) study systems compatibility in settings with one-sided plat- forms and direct network effects. We consider systems compatibility in settings with two-sided platforms and indirect network effects to develop an explanation why markets with...  View Details
