This paper studies the effect of incomplete information within a banking network. Banks are arranged in a network of claims. Claims are held either by other banks in the network or outside depositors. Within this framework, we analyze how incomplete information about the viability of bank assets...

I study an economy in which firms are interconnected and there is strategic complementarity in production decisions. Firms use the output of other firms as inputs to their own production. Furthermore, they make production choices before knowing the demand they face. The simultaneity of these...

We study how the heterogeneity of information impacts the efficiency of the business cycle and the design of optimal fiscal and monetary policy. We do so within a model that features a standard Dixit-Stiglitz demand structure, introduces dispersed private information about the underlying...

the potential heterogeneity in priors.

Collateral constraints on firm-level investment introduce a potentially powerful two-way feedback between the financial market and the real economy. On one hand, real economic activity forms the basis for asset dividends. On the other hand, asset prices affect collateral value, which in turn...

We study how the heterogeneity of information impacts the efficiency of the business cycle and the design of optimal fiscal and monetary policy. We do so within a model that features a standard Dixit-Stiglitz demand structure, introduces dispersed private information about the underlying...

This paper develops a novel theory of the origins of fluctuations. This theory dispenses with the dubious notions of exogenous disturbances to technologies, preferences, or mysterious wedges. Instead, it points out the central role that self-fulfilling expectations can play in shaping short-run...

I construct a dynamic economy in which agents are interconnected: the output produced by one agent is the consumption good of another. I show that this economy can generate recessions which resemble traffic jams. At the micro level, each individual agent waits for his own income to increase...

Does welfare improve when ?firms are better informed about the state of the economy and can better coordinate their decisions? We address this question in an elementary business-cycle model that highlights how the dispersion of information can be the source of both nominal and real rigidity....
