In standard Walrasian macro-finance models, pecuniary externalities such as fire sales lead to overinvestment in illiquid assets or underprovision of liquidity. We investigate whether imperfect competition (Cournot) improves welfare through internalizing the externality and find that this is far...

We argue that post-crisis bank regulation can explain large, persistent deviations from parity on basis trades requiring leverage. Documenting the financing cost and balance sheet impact on a broad array of basis trades for regulated institutions, we show that the implied return on equity on...

Does the intensity of supervision affect quantifiable outcomes at supervised firms? We develop a novel proxy to identify plausibly exogenous variation in the intensity of supervision across large U.S. bank holding companies (BHCs), based on the size rank of a BHC within its Federal Reserve...

We examine the effects of regulatory changes on banks' cost of capital and lending. Since the passage of the Dodd-Frank Act, the value-weighted CAPM cost of capital for banks has averaged 10.5 percent and declined by more than 4 percent on a within-firm basis relative to financial crisis...

We estimate the cost of capital for the banking industry and find that while the cost of capital soared for banks in the financial crisis, after the passage of the Dodd-Frank Act, the value-weighted cost of capital for banks fell differentially more than did the cost of capital for nonbanks. The...
