We explore how firms respond to downstream product shocks. We find that affected firms increase R&D and make additional safety-related investments in their existing assets-in-place. These investments vary with firm capabilities and across shock severity. Competitors appear to vicariously learn...

We provide a general non-parametric formula for aggregating microeconomic shocks in general equilibrium economies with distortions such as taxes, markups, frictions to resource reallocation, and nominal rigidities. We show that the macroeconomic impact of a shock can be boiled down into two...

We develop an endogenous growth model with heterogeneous firms facing financial frictions, where misallocation emerges explicitly as a crucial endogenous state variable and plays a significant role in driving economic growth through the valuation channel. The model illustrates that transient...

Firm entry dynamics are an integral part of the propagation of financial shocks to the real economy. A VAR documents that adverse financial shocks in the U.S. postwar period are associated with a fall in new firm creation and a fall in firm equity values. We propose a DSGE model with endogenous...

In the presence of persistent heterogeneity in capital, debt and total factor productivity, the effects of a financial shock are amplified and propagated through large and long-lived disruptions to the distribution of capital that, in turn, imply large and persistent reductions in aggregate...

We develop a tractable model of strategic debt renegotiation in which businesses are sequentially interconnected through their liabilities. This financing structure, which we refer to as a debt chain, gives rise to externalities as a lender's willingness to provide concessions to his...

We examine how collateral affects the cost of debt capital. Theories based on borrower moral hazard and limited pledgeable income predict that collateral increases the availability of credit and reduces its price. Testing these theories is complicated by the very selection problem which they...

We document that net equity issuance is considerably more sensitive to aggregate stock returns and Q's than to firm-level stock returns and Q's. Very similar patterns also emerge when we look at merger activity. In light of earlier work (Campbell 1991, Vuolteenaho 2002) which finds that...
