Central bank large-scale asset purchases, such as the purchase of securities of nonfinancial firms, can induce a misallocation of resources through their heterogeneous effect on firm cost of capital. First, we analytically demonstrate the mechanism in a two-period model. We then evaluate the...

A few sufficient statistics can identify the aggregate effects of distortions to firm investment in a class of general equilibrium models that can accommodate rich general equilibrium effects including endogenous firm entry. This result does not depend on the microfoundation of the distortion;...

This paper develops a heterogeneous firm general equilibrium model with endogenous innovation and default to assess policies related to leverage and debt overhang. We estimate key model parameters and find that near default, debt overhang induces nonlinearities in firm innovation decisions...

We study the role of firm heterogeneity in affecting business cycle dynamics and optimal stabilization policy. Firms differ in their degree of cyclicality, and hence, exposure to aggregate risk, leading to firm-specific risk premia that influence resource allocations. The heterogeneous firm...

We develop a theory linking "misallocation," i.e., dispersion in marginal products of capital (MPK), to macroeconomic risk. Dispersion in MPK depends on (i) heterogeneity in firm-level risk premia and (ii) the price of risk, and thus is countercyclical. We document strong empirical support for...
