<Para ID="Par1">We present a general equilibrium model of the new neoclassical synthesis that has the same level of generality as the Arrow–Debreu model. This involves a stochastic multi-period economy with a monetary sector and sticky commodity prices. We formulate the notion of a sticky price equilibrium...</para>

We introduce a two-period economy with asymmetric information about the state of nature that occurs in the second period. Each agent is endowed with an information structure that describes her (incomplete) ability to prove whether or not a state has occurred. We show that if the number of states...

We present an analytically tractable dynamic stochastic general equilibrium model that incorporates micro-level fixed and convex adjustment costs. We provide an explicit characterization of equilibrium dynamics by a system of nonlinear stochastic difference equations. We provide general...

We consider a general equilibrium model of trade ex ante with differential information in which agents choose plans of state-contingent lists of bundles. Being unable to verify that the state of nature is s and not t, an agent has to accept the delivery of any bundle in the list for delivery in...

We study internalization of production externalities in perfectly competitive markets where production plans are decided by majority voting. Since shareholders want firms to maximize dividends of portfolios rather than profits, they are interested in some internalization. Two governances, namely...

This paper studies a class of general equilibrium economies in which the individuals’ endowments depend on privately observed effort choices and the financial markets are endogenous. The environment is modeled as a two-stage game. Individuals first make strategic financial-innovation...
