That of the multiplier is a largely debated issue. Several studies propose estimates for it. This paper answers the question of how inequality affects the value of the multiplier. The proposed formulation is analytically derived from the Lorenz curve of income by means of Zanardi asymmetry...

The paper surveys the recent work on economics of information with endogenous information structures where individuals can directly communicate information with each other. We consider the theoretical work on cheap talk, Bayesian persuasion, and information design, and review the implications of...

Principal-agent models take outside options, determining participation and incentive constraints, as given. We construct a general equilibrium model where workers' reservation wages and the maximum punishment acceptable before workers quit are instead determined endogenously. We simultaneously...

The global financial crisis has forced standard macroeconomics to re-examine the plausibility of its assumptions and the adequacy of the policy prescriptions flowing from those assumptions. We believe a renewal of macroeconomic thinking and macroeconomic modeling is possible by recognizing that...

We analyze the individual and macroeconomic impacts of heterogeneous expectations and action rules within an agent-based model populated by heterogeneous, interacting firms. Agents have to cope with a complex evolving economy characterized by deep uncertainty resulting from technical change,...

We show that supply networks are inefficiently, and insufficiently, resilient. Upstream firms can expand their production capacity to hedge against supply and demand shocks. But the social benefits of such investments are not internalized due to market power and market incompleteness. Upstream...
