Existing literature continues to be unable to offer a convincing explanation for the volatility of the stochastic discount factor in real world data. Our work provides such an explanation. We do not rely on frictions, market in completeness or transactions costs of any kind. Instead, we modify a...

We examine the equilibrium effects of college financial aid policies building an overlapping generations life cycle model with education, labor supply, and saving decisions. Cognitive and non-cognitive skills of children depend on parental education and skills, and affect education and labor...

We develop an efficient and easy-to-use computational method for solving a wide class of general equilibrium heterogeneous agent models with aggregate shocks, together with an open source suite of codes that implement our algorithms in an easy-to-use toolbox. Our method extends standard...

We study business cycle fluctuations in heterogeneous-agent general equilibrium models that feature both intensive and extensive margins of labor supply. A nonconvexity in the mapping between time devoted to work and labor services combined with idiosyncratic shocks generates operative extensive...

What is it about modern capitalist economies that allows them, in contrast to all earlier societies, to generate sustained growth in productivity and living standards? It is widely agreed that the productivity growth of the industrialized economies is mainly an ongoing intellectual achievement,...

Artificial states are those in which political borders do not coincide with a division of nationalities desired by the people on the ground. We propose and compute for all countries in the world two new measures how artificial states are. One is based on measuring how borders split ethnic groups...

We argue that a 2-agent version of the standard New Keynesian model—where a “worker” receives only labor income and a “capitalist” only profit income— offers insights about how income inequality affects the monetary transmission mechanism. Under rigid prices, monetary policy affects...

This paper presents an Agent-Based Model (ABM) that seeks to explain the concordance of sluggish growth of productivity and of real wages found in macro-economic statistics, and the increased dispersion of firm productivity and worker earnings found in micro level statistics in advanced...

We analyze the role of household heterogeneity for the response of the macroeconomy to aggregate shocks. After summarizing how macroeconomists have incorporated household heterogeneity and market incompleteness in the study of economic fluctuations so far, we outline an emerging framework that...

The goal of this paper is to simultaneously unbundle two interacting reduced-form building blocks of traditional macroeconomic models: the representative agent and the aggregate production function. We introduce a broad class of disaggregated general equilibrium models with Heterogeneous Agents...
