This study proposes that heterogeneous household portfolio choices within a country and across countries offer an explanation for global imbalances. We construct a stochastic growth multi-country model in which heterogeneous agents face the following restrictions on asset trade. First, the...

We present a macroeconomic model with a financial intermediary sector subject to an equity capital constraint. The novel aspect of our analysis is that the model produces a stochastic steady state distribution for the economy, in which only some of the states correspond to systemic risk states....

with theories of biased technological adoption but hard to rationalize in a neoclassical framework.

We investigate the welfare effects of vertical integration in U.S. multichannel television markets. Vertical integration in this market can enhance efficiency by aligning investment incentives and/or reducing double marginalization, but can also increase market power by encouraging raising...

Aging populations and increasing health-care costs will lead to an explosion in costs from long-term care (LTC) for permanently disabled elderly citizens. Governments are considering and implementing different kinds of policy responses, among them government-provided minimal care combined with...

This paper develops methods to study the evolution of agents' expectations and uncertainty in general equilibrium models. A central insight consists of recognizing that the evolution of agents' beliefs can be captured by defining a set of regimes that are characterized by the degree of agents'...

This is a theory of endogenous volatility over the business cycle based on firm-level intangible expenditures. We propose a firm dynamics model with endogenous market participation. Firms that incur higher intangible expenses are able to serve more markets and diversify market-specific demand...

Abstract

We study the dynamics of how private information is resolved in credit markets and its dependence on systematic uncertainty in collateral value. We develop a model in which all borrowers have verifiable income that can be collateralized, but only good borrowers have additional income that is...

U.S. financial institutions have traditionally insured the typical U.S. household against persistent shocks to U.S. inflation through the U.S. mortgage market. The bond risk premium is effectively the price of long-run inflation risk insurance charged by these U.S. intermediaries. Starting in...
