Predictable polarization is everywhere. We can often predict the different directions that people’s opinions—including our own—will shift over time. Empirical studies suggest that this is so whenever evidence is ambiguous, a fact that’s often thought to demonstrate human bias or...

We develop a quantitative framework in which income inequality arises endogenously in response to productivity shocks. The framework accommodates sectoral inputoutput linkages, arbitrary elasticities of factors and intermediates, and heterogeneous workers that endogenously choose to supply their...

We investigate the geometry of finite datasets defined by equilibrium prices, income distributions, and total resources. We show that the equilibrium condition imposes no restrictions if total resources are collinear, a property that is robust to small perturbations. We also show that the set of...

We provide a theoretical demonstration that an exponential income distribution will emerge spontaneously in a standard Arrow-Debreu general equilibrium model, which is intended to describe the income structure of the low- and middle-class in a well-functioning free-market country. Furthermore,...

We incorporate a wage bargaining structure in a dynamic general equilibrium model and show how this feature changes short and long-run properties of equilibria compared with a perfectly competitive setting. We discuss how employment, capital, and income shares respond to wage setting shocks and...
