May 2019A Framework for Debt-Maturity Management
with Galo Nuño, Juan Passadore: w25808
We characterize the optimal debt-maturity management problem of a government in a small open economy. The government issues a continuum of finite-maturity bonds in the presence of liquidity frictions. We find that the solution can be decentralized: the optimal issuance of a bond of a given maturity is proportional to the difference between its market price and its domestic valuation, the latter defined as the price computed using the government’s discount factor. We show how the steady-state debt distribution decreases with maturity. These results hold when extending the model to incorporate aggregate risk or strategic default.
April 2016Financial Frictions in Production Networks
with Jennifer La’O: w22212
We study how an economy’s production structure determines the response of aggregate output and employment to sectoral financial shocks. In our framework, economic production is organized in an input-output network in which firms face financial constraints on their working capital. We show how sectoral financial shocks propagate through the network and manifest at the aggregate level through two channels: a fall in total factor productivity and an aggregate labor wedge distortion. The strength of each channel depends on the overall network architecture and the location of shocks. Finally, we calibrate our model to the U.S. input-output tables and use it to quantitatively assess the role of the network multiplier within the context of the recent Financial Crisis and the Great Recession.
September 2014Banks, Liquidity Management and Monetary Policy
with Javier Bianchi: w20490
We develop a new tractable model of banks' liquidity management and the credit channel of monetary policy. Banks finance loans by issuing demand deposits. Because loans are illiquid, deposit transfers across banks must be settled with reserves. Deposit withdrawals are random, and banks manage liquidity risk by holding a precautionary buffer of reserves. We show how different shocks affect the banking system by altering the trade-off between profiting from lending and incurring greater liquidity risk. Through various tools, monetary policy affects the real economy by altering that trade-off. In a quantitative application, we study the driving forces behind the decline in lending and liquidity hoarding by banks during the 2008 financial crisis. Our analysis underscores the importance of disr...
