International reserves and rollover risk
This paper provides a theoretical framework for quantitatively investigating the optimal accumulation of international reserves as a hedge against rollover risk. We study a dynamic model of endogenous default in which the government faces a tradeoff between the insurance benefits of reserves and the cost of keeping larger gross debt positions. A calibrated version of our model is able to rationalize large holdings of international reserves, as well as the procyclicality of reserves and gross debt positions. Model simulations are also consistent with spread dynamics and other key macroeconomic ...

Macroeconomic effects of Federal Reserve forward guidance
A large output gap accompanied by stable inflation close to its target calls for further monetary accommodation, but the zero lower bound on interest rates has robbed the Federal Open Market Committee (FOMC) of the usual tool for its provision. We examine how public statements of FOMC intentions?forward guidance?can substitute for lower rates at the zero bound. We distinguish between Odyssean forward guidance, which publicly commits the FOMC to a future action, and Delphic forward guidance, which merely forecasts macroeconomic performance and likely monetary policy actions. Others have shown ...

Higher-Order Perturbation Solutions to Dynamic, Discrete-Time Rational Expectations Models
We present an algorithm and software routines for computing nth order Taylor series approximate solutions to dynamic, discrete-time rational expectations models around a nonstochastic steady state. The primary advantage of higher-order (as opposed to first- or second-order) approximations is that they are valid not just locally, but often globally (i.e., over nonlocal, possibly very large compact sets) in a rigorous sense that we specify. We apply our routines to compute first- through seventh-order approximate solutions to two standard macroeconomic models, a stochastic growth model and a ...

From the horse’s mouth: how do investor expectations of risk and return vary with economic conditions?
Data obtained from monthly Gallup/UBS surveys from 1998-2007 and from a special supplement to the Michigan Surveys of Consumer Attitudes, run in 22 monthly surveys between 2000-2005, are used to analyze stock market beliefs and portfolio choices of household investors. We show that the key variables found to be positive predictors of actual stock returns in the asset-pricing literature are also highly correlated with investor?s reported expected returns, but with the opposite sign. Moreover, analysis of the micro data indicates that expectations of both risk and returns on stocks are strongly ...

Monetary Policy Expectations at the Zero Lower Bound
Obtaining monetary policy expectations from the yield curve is difficult near the zero lower bound (ZLB). Standard dynamic term structure models, which ignore the ZLB, can be misleading. Shadow-rate models are better suited for this purpose, because they account for the distributional asymmetry in projected short rates induced by the ZLB. Besides providing better interest rate fit and forecasts, our shadow-rate models deliver estimates of the future monetary policy liftoff from the ZLB that are closer to survey expectations. We also document significant improvements for inference about ...

Have we underestimated the likelihood and severity of zero lower bound events?
Before the recent recession, the consensus among researchers was that the zero lower bound (ZLB) probably would not pose a significant problem for monetary policy as long as a central bank aimed for an inflation rate of about 2 percent; some have even argued that an appreciably lower target inflation rate would pose no problems. This paper reexamines this consensus in the wake of the financial crisis, which has seen policy rates at their effective lower bound for more than two years in the United States and Japan and near zero in many other countries. We conduct our analysis using a set of ...

Institutional causes of macroeconomic volatility
In this paper we investigate the relation between the quality of institutions and macroeconomic volatility. Using instrumental variable regressions, we show that higher barriers to entry lead to higher volatility. In particular, a one standard deviation increase in entry costs increases the standard deviation of output growth by roughly 40% of its average value in our sample. To the contrary, property rights protection has no statistically significant effect on volatility.

An approximate dual-self model and paradoxes of choice under risk
We derive a simplified version of the model of Fudenberg and Levine [2006, 2011] and show how this approximate model is useful in explaining choice under risk. We show that in the simple case of three outcomes, the model can generate indifference curves that ?fan out? in the Marshack-Machina triangle, and thus can explain the well-known Allais and common ratio paradoxes that models such as prospect theory and regret theory are designed to capture. At the same time, our model is consistent with modern macroeconomic theory and evidence and generates predictions across a much wider set of ...

Does neoclassical theory account for the effects of big fiscal shocks? Evidence from World War II
There is much debate about the usefulness of the neoclassical growth model for assessing the macroeconomic impact of fiscal shocks. We test the theory using data from World War II, which is by far the largest fiscal shock in the history of the United States. We take observed changes in fiscal policy during the war as inputs into a parameterized, dynamic general equilibrium model and compare the values of all variables in the model to the actual values of these variables in the data. Our main finding is that the theory quantitatively accounts for macroeconomic activity during this big fiscal ...

Kalman filtering with truncated normal state variables for Bayesian estimation of macroeconomic models
A pair of simple modifications-in the forecast error and forecast error variance-to the Kalman filter recursions makes possible the filtering of models in which one or more state variables is truncated normal and latent. Such recursions are broadly applicable to macroeconometric models, such as vector autoregressions and estimated dynamic stochastic general equilibrium models, that have one or more probit-type equation.
