Working Paper
Macroeconomic Effects of Banking Sector Losses across Structural Models
The macro spillover effects of capital shortfalls in the financial intermediation sector are compared across five dynamic equilibrium models for policy analysis. Although all the models considered share antecedents and a methodological core, each model emphasizes different transmission channels. This approach delivers "model-based confidence intervals" for the real and financial effects of shocks originating in the financial sector. The range of outcomes predicted by the five models is only slightly narrower than confidence intervals produced by simple vector autoregressions.

Working Paper
Innovation, Productivity, and Monetary Policy
To what extent can monetary policy impact business innovation and productivity growth? We use a New Keynesian model with endogenous total factor productivity (TFP) to quantify the TFP losses due to the constraints on monetary policy imposed by the zero lower bound (ZLB) and the TFP benefits of tightening monetary policy more slowly than currently anticipated. In the model, monetary policy influences firms incentives to develop and implement innovations. We use evidence on the dynamic effects of R&D and monetary shocks to estimate key parameters and assess model performance. The model suggests significant TFP losses due to the ZLB.

Working Paper
Banks, Capital Flows and Financial Crises
This paper proposes a macroeconomic model with financial intermediaries (banks), in which banks face occasionally binding leverage constraints and may endogenously affect the strength of their balance sheets by issuing new equity. The model can account for occasional financial crises as a result of the nonlinearity induced by the constraint. Banks' precautionary equity issuance makes financial crises infrequent events occurring along with "regular" business cycle fluctuations. We show that an episode of capital infl ows and rapid credit expansion, triggered by low country interest rates, leads banks to endogenously decrease the rate of equity issuance, contributing to an increase in the likelihood of a crisis. Macroprudential policies directed at strengthening banks' balance sheets, such as capital requirements, are shown to lower the probability of financial crises and to enhance welfare.

Working Paper
A Model of Slow Recoveries from Financial Crises
This paper documents highly persistent effects of financial crises on output, labor productivity and employment in a sample of emerging economies. To address these facts, it introduces a quantitative macroeconomic model that includes endogenous TFP growth through firm creation. Firm creators obtain funding from a financial intermediation sector which is subject to frictions. These frictions become especially severe in a financial crisis, increasing the cost of credit for firm creators and thereby lowering the growth rate of aggregate TFP. As a consequence, the model produces medium-run dynamics following crises that are in line with the data.

Discussion Paper
Financial Crises and the Desirability of Macroprudential Policy
The global financial crisis has put financial stability risks?and the potential role of macroprudential policies in addressing them?at the forefront of policy debates. The challenge for macroeconomists is to develop new models that are consistent with the data while being able to capture the highly nonlinear nature of crisis episodes. In this post, we evaluate the impact of a macroprudential policy that has the government tilt incentives for banks to encourage them to build up their equity positions. The government has a role since individual banks do not internalize the systemic benefit of having more bank equity. Our model allows for an evaluation of the tradeoff between the size of such incentives and the probability of a future financial crisis.

Credit spreads, financial crises, and macroprudential policy
Credit spreads display occasional spikes and are more strongly countercyclical in times of financial stress. Financial crises are extreme cases of this nonlinear behavior, featuring skyrocketing credit spreads, sharp losses in bank equity, and deep recessions. We develop a macroeconomic model with a banking sector in which banks? leverage constraints are occasionally binding and equity issuance is endogenous. The model captures the nonlinearities in the data and produces quantitatively realistic crises. Precautionary equity issuance makes crises infrequent but does not prevent them altogether. When determining the intensity of capital requirements, the macroprudential authority faces a trade-off between the benefits of reducing the risk of a financial crisis and the welfare losses associated with banks? constrained ability to finance risky capital investments..

Exchange rate dynamics and monetary spillovers with imperfect financial markets
We use a two-country New Keynesian model with financial frictions and dollar debt in balance sheets to investigate the foreign effects of U.S. monetary policy. Financial amplification works through an endogenous deviation from uncovered interest parity (UIP) arising from limits to arbitrage in private intermediation. Combined with dollar trade invoicing, this mechanism leads to large spillovers from U.S. policy, consistent with the evidence. Foreign monetary policies that attempt to stabilize the exchange rate reduce welfare and may exacerbate exchange rate volatility. We document empirically a link between UIP deviations and measures of credit market frictions, as predicted by the model.
