Factor Specificity and Real Rigidities
We develop a multisector model in which capital and labor are free to move across firms within each sector, but cannot move across sectors. To isolate the role of sectoral specificity, we compare our model with otherwise identical multisector economies with either economy-wide factor markets (as in Chari et al. 2000) or firm-specific factor markets (as in Woodford 2005). Sectoral specificity induces within-sector strategic substitutability and across-sector strategic complementarity in price setting. Our model can produce either more or less monetary non-neutrality than those other two ...

Estimating the cross-sectional distribution of price stickiness from aggregate data
We estimate a multisector sticky-price model for the U.S. economy in which the degree of price stickiness is allowed to vary across sectors. For this purpose, we use a specification that allows us to extract information about the underlying cross-sectional distribution from aggregate data. Identification is possible because sectors play different roles in determining the response of aggregate variables to shocks at different frequencies: Sectors where prices are stickier are relatively more important in determining the low-frequency response. Estimating the model using only aggregate data on ...

Approximating Multisector New Keynesian Models
We show that a calibrated three-sector model with a suitably chosen distribution of price stickiness can closely approximate the dynamic properties of New Keynesian models with a much larger number of sectors. The parameters of the approximate three-sector distribution are such that both the approximate and the original distributions share the same (i) average frequency of price changes, (ii) cross-sectional average of durations of price spells, (iii) cross-sectional standard deviation of durations of price spells, (iv) the cross-sectional skewness of durations of price spells, and (v) ...

Do people undestand monetary policy?
We combine questions from the Michigan Survey about the future path of prices, interest rates, and unemployment to investigate whether U.S. households are aware of the so-called Taylor (1993) rule. For comparison, we perform the same analysis using questions from the Survey of Professional Forecasters. Our findings support the view that some households form their expectations about the future path of interest rates, inflation, and unemployment in a way that is consistent with Taylor-type rules. The extent to which this happens, however, does not appear to be uniform across income and ...

Loss aversion, asymmetric market comovements, and the home bias
Loss aversion has been used to explain why a high equity premium might be consistent with plausible levels of risk aversion. The intuition is that the different utility impact of wealth gains and losses leads loss-averse investors to behave similarly to investors with high risk aversion. But if so, should these agents not perceive larger gains from international diversification than standard expected-utility preference agents with plausible levels of risk aversion? They might not, because comovements in international stock markets are asymmetric: Correlations are higher in market downturns ...

Aggregation and the PPP puzzle in a sticky-price model
We study the purchasing power parity (PPP) puzzle in a multisector, two-country, sticky-price model. Firms' price stickiness differs across sectors, in accordance with recent microeconomic evidence on price setting in various countries. Combined with local currency pricing, these differences lead sectoral real exchange rates to exhibit heterogeneous dynamics. We show that in this economy, deviations of the real exchange rate from PPP are more volatile and persistent when compared with a counterfactual one-sector world economy that features the same average frequency of price changes and is ...

Policy initiatives in the global recession: what did forecasters expect?
The global recession of 2008-09 led to monetary and fiscal policy responses by central banks and government authorities that were often unconventional in size and scope. A study of expansionary measures employed during the recession suggests that overall, the policies were likely effective in shaping the outlook for a recovery, as forecasters raised their expectations of inflation and GDP growth after the policies? implementation. From this perspective, the policies stimulated economic activity and prevented deflationary pressures during the financial crisis.

Aggregation and the PPP puzzle in a sticky-price model
We study the purchasing power parity (PPP) puzzle in a multi-sector, two-country, sticky- price model. Across sectors, firms differ in the extent of price stickiness, in accordance with recent microeconomic evidence on price setting in various countries. Combined with local currency pricing, this leads sectoral real exchange rates to have heterogeneous dynamics. We show analytically that in this economy, deviations of the real exchange rate from PPP are more volatile and persistent than in a counterfactual one-sector world economy that features the same average frequency of price changes, and ...

The persistent effects of a false news shock
In September 2008, a six-year-old article about the 2002 bankruptcy of United Airlines' parent company resurfaced on the Internet and was mistakenly believed to be reporting a new bankruptcy filing by the company. This episode caused the parent company's stock price to drop by as much as 76 percent in just a few minutes, before NASDAQ halted trading. After the "news" had been identified as false, the stock price rebounded, but still ended the day 11.2 percent below the previous close. We use this natural experiment and a simple asset-pricing model to study the aftermath of this false news ...

Real exchange rate dynamics in sticky-price models with capital
The standard argument for abstracting from capital accumulation in sticky-price macro models is based on their short-run focus: over this horizon, capital does not move much. This argument is more problematic in the context of real exchange rate (RER) dynamics, which are very persistent. In this paper we study RER dynamics in sticky-price models with capital accumulation. We analyze both a model with an economy-wide rental market for homogeneous capital, and an economy in which capital is sector specific. We find that, in response to monetary shocks, capital increases the persistence and ...
