Researchers often test firm conduct models using pass-through regressions or instrumental variables (IV) methods. The former has limited applicability; the latter relies on potentially irrelevant instruments. We show the falsifiable restriction underlying the IV method generalizes the...

We study the role of firms' political influence on the effectiveness of government spending using ARRA as a laboratory. Through an IV approach, we show that a 10 percentage points increase in the share of politically connected spending lowers the job creation effect of stimulus by 33 percent at...

We study the propagation of nominal shocks in a dispersed information economy where firms learn from and respond to information generated by their activities in product and factor markets. We prove the existence of a "Hayekian benchmark", defined by conditions under which imperfect information...

Heterogeneous firm models are ubiquitous in modern macroeconomics. We revisit a central feature of these models: the idiosyncratic shock process faced by firms. Using a large representative firm-level dataset, we document nonparametrically that the common assumption, a Gaussian AR(1) shock...

I provide a rigorous framework for accounting for corporate greenhouse gas emissions, based on the Greenhouse Gas Protocol. I show that only Scope 1 emissions are of interest from a national policy perspective: that emissions in Scopes 2 and 3 are duplicative, and that downstream Scope 3...

We study how government policies and corporate commitments to decarbonize interact under two externalities: environmental damages and green innovation spillovers. Unconstrained carbon taxes and innovation subsidies could achieve first-best outcomes, but when government policies face constraints,...
