Join us to hear from Yu Awaya, University of Rochester, presenting, "Spreading Information via Social Networks: An Irrelevance Result."

Abstract: An informed planner wishes to spread information among a group of agents in order to induce efficient coordination—say the adoption of a new technology with positive externalities. The agents are connected via a social network. The planner informs a seed and then the information spreads via the network. While the structure of the network affects the...

Join us to hear from Mehrdad Moharrami, who will present “A Policy Gradient Algorithm for the Risk-Sensitive Exponential Cost MDP."

Abstract: We study the risk-sensitive exponential cost MDP formulation and develop a trajectory-based gradient algorithm to find the stationary point of the cost associated with a set of parameterized policies. We derive a formula that can be used to compute the policy gradient from (state, action, cost) information collected from sample paths of the MDP for each...

Join us to hear from Josh Lerner, Harvard University. His presentation is titled, "What Do Impact Investors Do Differently?" 

Abstract: In recent years, impact investors—private investors who seek to generate simultaneously financial and social returns—have attracted intense interest and controversy. We analyze a novel, comprehensive data set of impact and traditional investors to assess how the non-financial characteristics of impact portfolios differ from their traditional counterparts. First...

Join us to hear from Colin Ward, University of Minnesota. His presentation is titled, "Appropriated Growth". 

Abstract: We assess how labor mobility affects intangible investment through the lens of a structural model that features knowledge spillovers and an agency conflict between investors and key employees. Our calibration to US data targets responses of employee turnover and firms’ intangible investment to variation in workers’ outside option values that are identified by state-level...

The Affordable Care Act was the most significant health care reform in the U.S. in half a century, but health care reform is never over. Continued high rates of insurance, high health care costs, and poor health care outcomes for many Americans demand continued efforts to improve the U.S. health care system. In this lecture entitled "Health Care Reform Never Ends," Professor Gruber will discuss how we got to where we are on health care policy and the central issues facing the U.S. in the coming...

Join us to hear from Tarun Sabarwal, University of Kansas, presenting, "General Theory of Equilibrium in Models with Complementarities".

Abstract: We unify and generalize the equilibrium theory of foundational models of complementarities used widely
in economics and other disciplines. Widely used results for existence of extremal equilibrium, nonempty
complete lattice structure of the equilibrium set, and monotone comparative statics (MCS) of extremal
equilibria are unified and generalized...
