Do credit constraints amplify macroeconomic fluctuations?
Previous studies on financial frictions have been unable to establish the empirical significance of credit constraints in macroeconomic fluctuations. This paper argues that the muted impact of credit constraints stems from the absence of a mechanism to explain the observed persistent comovements between housing prices and business investment. We develop such a mechanism by incorporating two key features into a DSGE model: we identify shocks that shift the demand for collateral assets and we allow productive agents to be credit-constrained. A combination of these two features enables our model ...

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 ...

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 ...

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 ...

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.

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 ...

A cross-country quarterly database of real house prices: a methodological note
We build from (mainly) publicly available national sources a database of (nominal and real) house prices?complemented with data on private disposable income (PDI)?for 19 advanced countries at a quarterly frequency, starting in the first quarter of 1975. We select a house price index for each country that is consistent with the U.S. FHFA quarterly nationwide house price index for existing single-family houses (formerly called OFHEO house price index), and extend the country series back to 1975 with available historical data whenever necessary. Each house price index is seasonallyadjusted over ...

Optimal monetary policy in a two country model with firm-level heterogeneity
This paper studies non-cooperative monetary policy in a two country general equilibrium model where international economic integration is endogenised through firm-level heterogeneity and monopolistic competition. Economic integration between countries is a source of policy competition, generating higher long-run inflation, and increased gains from monetary cooperation.

'Rational inattention' guides overloaded brains, helps economists understand market behavior
Between Internet news sources, social media and email, people are awash in information, most of it accessible at near-zero cost. Yet, humans possess only a finite capacity to process all of it. The average email user, for example, receives dozens of messages per day. The messages can?t all receive equal attention. How carefully does someone read an email from a sibling or friend before crafting a reply? How closely does a person read an email from the boss?> ; Limitations on the ability to process information force people to make choices regarding the subjects to which they pay more or less ...
