Now that Congress has passed the Dodd-Frank Wall Street Reform and Consumer Protection Act, regulators promulgating the rules under this new bill must tackle a major problem that the reform bill addresses only indirectly. This is the problem of excessive “leverage” – financing with too...

I construct a model of money and credit where financial intermediaries write deposit contracts with economic agents to intermediate credit transactions. A preference shock is private information to a depositor, which is costly for intermediaries to observe. Financial intermediaries create...

The aim of this work is to compare and contrast different ways of modeling financial shocks and financial intermediaries in the Dynamic Stochastic General Equilibrium models (DSGE models) and to discuss the empirical evidence on the importance of modeling financial sector and financial shocks in...

Central banks repo market operations and liquidity infusions occasion a structural liquidity mismatch in bank balance sheets and increase the dependence on central bank liquidity. This paper argues for what I term “Circular Monetary Economics”, an approach to monetary policy that seeks to...

During and after the Great Recession of 2008-09, conventional monetary policy in the United States and many other advanced economies was constrained by the effective lower bound (ELB) on nominal interest rates. Several central banks implemented large-scale asset purchase (LSAP) programs, more...

We propose a novel framework to analyze how policy-makers can manage risks to the median projection and risks specific to the tail of gross domestic product (GDP) growth. By combining a quantile regression of GDP growth with a vector autoregression, we show that monetary and macroprudential...

In this essay I discuss how theoretical models in finance and economics are used in ways that make them “chameleons” and how chameleons devalue the intellectual currency and muddy policy debates. A model becomes a chameleon when it is built on assumptions with dubious connections to the real...

The 2007-8 global financial crisis has shown the failure of private finance to efficiently allocate capital to finance real capital development. The resilience and stability of Brazil’s financial system has received attention, since it navigated relatively smoothly through the Great Recession...

Bank runs may serve to communicate information across agents, and thus enhance rather than thwart allocation efficiency by making the fundamentals determine the asset prices. Figuratively speaking, banks die (go bankrupt) singing a swan song (revealing hidden information). In this way bank runs...

In this paper I estimate a New Keynesian Dynamic Stochastic General Equilibrium model for the Euro Area, which closely follows the structure of the model developed by Smets and Wouters (2003, 2005, 2007), with the addition of the so-called financial accelerator mechanism developed in Bernanke,...
