Latent Variables Analysis in Structural Models: A New Decomposition of the Kalman Smoother
This paper advocates chaining the decomposition of shocks into contributions from forecast errors to the shock decomposition of the latent vector to better understand model inference about latent variables. Such a double decomposition allows us to gauge the inuence of data on latent variables, like the data decomposition. However, by taking into account the transmission mechanisms of each type of shock, we can highlight the economic structure underlying the relationship between the data and the latent variables. We demonstrate the usefulness of this approach by detailing the role of ...

Credit Market Frictions, Business Cycles, and Monetary Policy: The Research Contributions of Charles Carlstrom and Timothy Fuerst
Charles Carlstrom and Timothy Fuerst were prolific and prominent research economists who, until their untimely deaths a few years ago, were long-associated with the Federal Reserve Bank of Cleveland. Their myriad contributions include the incorporation of financial market imperfections into macroeconomic models and the study of optimal monetary policy. We provide an overview of their work and summarize a few key themes from a research conference held in their honor.

Estimating contract indexation in a financial accelerator model
This paper addresses the positive implications of indexing risky debt to observable aggregate conditions. These issues are pursued within the context of the celebrated financial accelerator model of Bernanke, Gertler and Gilchrist (1999). The principal conclusions include: (1) the estimated level of indexation is significant, (2) the business cycle properties of the model are significantly affected by this degree of indexation, (3) the importance of investment shocks in the business cycle depends upon the estimated level of indexation, and (4) although the data prefers the financial model ...

Fiscal multipliers under an interest rate peg of deterministic vs. stochastic duration
This paper revisits the size of the fiscal multiplier. The experiment is a fiscal expansion under the assumption of a pegged nominal rate of interest. We demonstrate that a quantitatively important issue is the articulation of the exit from the policy experiment. If the monetary-fiscal expansion is stochastic with a mean duration of T periods, the fiscal multiplier can be unboundedly large. However, if the monetary-fiscal expansion is for a fixed T periods, the multiplier is much smaller. Our explanation rests on a Jensen?s inequality type argument: the deterministic multiplier is convex in ...

Inflation and output in New Keynesian models with a transient interest rate peg
Recent monetary policy experience suggests a simple diagnostic for models of monetary non-neutrality. Suppose the central bank pegs the nominal interest rate below steady state for a reasonably short period of time. Familiar intuition suggests that this should be modestly inflationary, and a reasonable model should deliver such a prediction. We pursue this simple diagnostic in several variants of the familiar Dynamic New Keynesian (DNK) model. Some variants of the model produce counterintuitive inflation reversals where the effect of the interest rate peg can switch from highly inflationary ...

Privately optimal contracts and suboptimal outcomes in a model of agency costs
This paper derives the privately optimal lending contract in the celebrated financial accelerator model of Bernanke, Gertler and Gilchrist (1999). The privately optimal contract includes indexation to the aggregate return on capital, household consumption, and the return to internal funds. Although privately optimal, this contract is not welfare maximizing as it leads to a sub-optimally high price of capital. The welfare cost of the privately optimal contract (when compared to the planner outcome) is significant. A menu of time-varying taxes and subsidies can decentralize the planner?s ...

Monetary Policy Options at the Effective Lower Bound : Assessing the Federal Reserve's Current Policy Toolkit
We simulate the FRB/US model and a number of statistical models to quantify some of the risks stemming from the effective lower bound (ELB) on the federal funds rate and to assess the efficacy of adjustments to the federal funds rate target, balance sheet policies, and forward guidance to provide monetary policy accommodation in the event of a recession. Over the next decade, our simulations imply a roughly 20 to 50 percent probability that the federal funds rate will be constrained by the ELB at some point. We also find that forward guidance and balance sheet polices of the kinds used in ...

Indexed debt contracts and the financial accelerator
This paper addresses the positive and normative implications of indexing risky debt to observable aggregate conditions. These issues are pursued within the context of the celebrated financial accelerator model of Bernanke, Gertler and Gilchrist (1999). The principal conclusions are that the optimal degree of indexation is significant, and that the business cycle properties of the model are altered under this level of indexation.

Do Sustainable Investment Strategies Hedge Climate Change Risks? Evidence from Germany's Carbon Tax
It is difficult to assess the effectiveness of investment strategies that screen companies based on environmental criteria to hedge climate change risk because physical risks have not yet fully materialized and policies to combat climate change are usually widely anticipated. This paper sidesteps these limitations by analyzing the stock market response to plausibly exogenous changes in expectations about the level of a carbon tax in Germany. The risk-adjusted return on two sustainable investment approaches---screening companies based on environmental scores and on firms' carbon ...
