PDFLong-Term Changes in Labor Supply and Taxes: Evidence from OECD Countries, 1956-2004
By Lee Ohanian, Andrea Raffo, and Richard Rogerson
RWP 06-16, December 2006
We document large differences in trend changes in hours worked across OECD countries over the period 1956-2004. We then assess the extent to which these changes are consistent with the intratemporal first order condition from the neoclassical growth model. We find large and trending deviations from this condition, and that the model can account for virtually none of the changes in hours worked. We then extend the model to incorporate observed changes in taxes. Our findings suggest that taxes can account for much of the variation in hours worked both over time and across countries.

PDFA Tale of Two Rigidities: Sticky Prices in a Sticky-Information Environment
By Edward S. Knotek
RWP 06-15, December 2006; updated June 2010
Macroeconomic models with microeconomic foundations afford the opportunity to compare the model’s behavior with empirical evidence at the macro and micro levels. This paper proposes a model that combines two strands of the literature on stickiness to match both sets of empirical facts. (1) Firms acquire information infrequently, as in Mankiw and Reis (2002), resulting in sticky information. (2) Firms face menu costs to change prices, leading to state-dependent sticky prices at the micro level. I estimate key structural parameters via indirect inference and show that a model of sticky prices in a sticky-information environment, combined with considerable real rigidity, is consistent with micro and macro evidence. In this context, sticky prices are not only useful in matching micro data on the size of price changes and the duration between adjustments; they also improve the model’s ability to fit the macro data, as embodied in an empirical Phillips curve.

PDFSearch Frictions: Matching Aggregate and Establishment Observations
By Russell Cooper, John Haltiwanger, and Jonathan L. Willis
RWP 06-14, December 2006; updated June 2007
We estimate a search model to match hours, employment, vacancies and unemployment at the micro and macro levels. We establish a set of facts concerning the variability of unemployment and vacancies in the aggregate and the distribution of net employment growth and the comovement of hours and employment growth at the establishment level. A search model with non-convex costs of posting vacancies, establishment-level profitability shocks and a contracting framework to set hours provides a structure to understand these observations. The estimated model is able to capture both the aggregate and establishment-level facts.

PDFSticky Information and Sticky Prices
By Peter J. Klenow and Jonathan L. Willis
RWP 06-13, December 2006; updated June 2007
In the U.S. and Europe, prices change at least once a year. Yet nominal macro shocks seem to have real effects lasting well beyond a year. "Sticky information" models, as posited by Mankiw and Reis (2002), Sims (2003), and Woodford (2003), can reconcile micro flexibility with macro rigidity. We simulate a sticky information model in which price setters update information on macro shocks less frequently than information on micro shocks. We then examine price changes in the micro data underlying the U.S. CPI. Empirical price changes react to old information, just as sticky information models predict.

PDFAveraging Forecasts from VARs with Uncertain Instabilities
By Todd E. Clark and Michael W. McCracken
RWP 06-12, November 2006
A body of recent work suggests commonly–used VAR models of output, inflation, and interest rates may be prone to instabilities. In the face of such instabilities, a variety of estimation or forecasting methods might be used to improve the accuracy of forecasts from a VAR. These methods include using different approaches to lag selection, different observation windows for estimation, (over-) differencing, intercept correction, stochastically time–varying parameters, break dating, discounted least squares, Bayesian shrinkage, and detrending of inflation and interest rates. Although each individual method could be useful, the uncertainty inherent in any single representation of instability could mean that combining forecasts from the entire range of VAR estimates will further improve forecast accuracy. Focusing on models of U.S. output, prices, and interest rates, this paper examines the effectiveness of combination in improving VAR forecasts made with real–time data. The combinations include simple averages, medians, trimmed means, and a number of weighted combinations, based on: Bates-Granger regressions, factor model estimates, regressions involving just forecast quartiles, Bayesian model averaging, and predictive least squares–based weighting. Our goal is to identify those approaches that, in real time, yield the most accurate forecasts of these variables. We use forecasts from simple univariate time series models and the Survey of Professional Forecasters as benchmarks.

PDFEndogenous Monetary Policy Regime Changes
By Troy Davig and Eric M. Leeper
RWP 06-11, September 2006
This paper makes changes in monetary policy rules (or regimes) endogenous. Changes are triggered when certain endogenous variables cross specified thresholds. Rational expectations equilibria are examined in three models of threshold switching to illustrate that (i) expectations formation effects generated by the possibility of regime change can be quantitatively important; (ii) symmetric shocks can have asymmetric effects; (iii) endogenous switching is a natural way to formally model preemptive policy actions. In a conventional calibrated model, preemptive policy shifts agents’ expectations, enhancing the ability of policy to offset demand shocks; this yields a quantitatively significant “preemption dividend.”

PDFConsumption Amenities and City Population Density
By Jordan Rappaport
RWP 06-10, August 2006; updated January 2008
Previously titled "Consumption Amenities and City Crowdedness"
Population density varies widely among U.S. metro areas. A simple, static general equilibrium model demonstrates that moderate differences in metro areas’ consumption amenities can cause extremely large differences in their population density. Such amenities are more strongly capitalized into housing prices than into wages. Empirical results suggest that amenities do indeed help to support high density levels and that amenities are becoming a more important determinant of where people choose to live. Matching the empirical correlation between wages and density requires that amenities cause approximately one fifth of the cross-sectional variation in metro population density.

PDFForecasting with Small Macroeconomic VARs in the Presence of Instabilities
By Todd E. Clark and Michael W. McCracken
RWP 06-09, June 2006
Small-scale VARs have come to be widely used in macroeconomics, for purposes ranging from forecasting output, prices, and interest rates to modeling expectations formation in theoretical models. However, a body of recent work suggests such VAR models may be prone to instabilities. In the face of such instabilities, a variety of estimation or forecasting methods might be used to improve the accuracy of forecasts from a VAR. These methods include using different approaches to lag selection, observation windows for estimation, (over-) differencing, intercept correction, stochastically time--varying parameters, break dating, discounted least squares, Bayesian shrinkage, detrending of inflation and interest rates, and model averaging. Focusing on simple models of U.S. output, prices, and interest rates, this paper compares the effectiveness of such methods. Our goal is to identify those approaches that, in real time, yield the most accurate forecasts of these variables. We use forecasts from simple univariate time series models, the Survey of Professional Forecasters and the Federal Reserve Board's Greenbook as benchmarks.

PDFAmenities, Local Conditions, and Fiscal Determinants of Factor Growth in Rural America
By Eric Thompson, George Hammond, and Stephan Weiler
RWP 06-08, June 2006
This paper examines how amenities, asset indicators, and fiscal factors influence the growth in factors of production from 1972 to 1999 in the 466 non-metropolitan labor market areas in the continental United States. In developing our model of non-metropolitan factor markets, we combine the emphasis of Brown et al. (2003) on the affect of taxes and public expenditure policy on labor and capital formation with the emphasis of Beeson et al. (2001) on the importance of climate and natural features on localized population growth. We develop our own measure of capital stock in non-metropolitan areas using data from the Census of Manufacturing for 1967, 1972, 1977, 1982, 1987, and 1992. Results indicate that local taxes discourage both employment growth and manufacturing capital formation, but that local public infrastructure investment and the level of local entrepreneurship encourages employment growth. Amenities such as a favorable climate and the presence of surface water encourage the growth of employment, and greater local wealth, as measured by dividend, interest, and rent income, encourages the formation of manufacturing capital stock. Results fail to support an “export base” approach for rural economies where greater manufacturing capital stock encourages greater employment in a region.

PDFTargeting Inflation and the Fiscal Balance: What is the Optimal Policy Mix?
By Marcela Meirelles Aurelio
RWP 06-07, June 2006
This paper identifies optimal policy rules in the presence of explicit targets for both the inflation rate and public debt. This issue is investigated in the context of a dynamic stochastic general equilibrium model that describes a small open economy with capital accumulation, distortionary taxation and nominal price rigidities. The model is solved using a second-order approximation to the equilibrium conditions. Optimal policy features a strong anti-inflation stance and strict fiscal discipline. Targeting a domestic inflation index - as opposed to CPI - improves welfare because it reduces the inefficiencies that stem from both price stickiness and income taxes.

Population density varies widely across U.S. cities. A simple, static general equilibrium model suggests that moderate-sized differences in cities’ total factor productivity can account for such variation. Nevertheless, the productivity required to sustain above-average population densities considerably exceeds estimates of the increase in productivity caused by such high density. In contrast, increasing returns to scale may be able to sustain multiple equilibria at below-average population densities.

PDFRegime Changes and Monetary Stagflation
By Edward S. Knotek
RWP 06-05, May 2006
This paper examines whether monetary shocks can consistently generate stagflation in a dynamic, stochastic setting. I assume that the monetary authority can induce transitory shocks and longer-lasting monetary regime changes in its operating instrument. Firms cannot distinguish between these shocks and must learn about them using a signal extraction problem. The possibility of changes in the monetary regime greatly improves the ability of money to generate stagflation. This is true whether the regime actually changes or not. If the monetary regime changes on average once every ten years, stagflation occurs in 76% of model simulations. The intuition for this result is simple: increased output volatility due to learning coupled with inflation inertia produce conditions conducive to the emergence of stagflation. The incidence of stagflation can be reduced by a stable, transparent central bank.

PDFReal Rigidities and Nominal Price Changes
By Peter J. Klenow and Jonathan L. Willis
RWP 06-03, March 2006
A large literature seeks to provide microfoundations of price setting for macro models. A challenge has been to develop a model in which monetary policy shocks have the highly persistent effects on real variables estimated by many studies. Nominal price stickiness has proved helpful but not sufficient without some form of "real rigidity" or "strategic complementarity." We embed a model with a real rigidity a la Kimball (1995), wherein consumers flee from relatively expensive products but do not flock to inexpensive ones. We estimate key model parameters using micro data from the U.S. CPI, which exhibit sizable movements in relative prices of substitute products. When we impose a significant degree of real rigidity, fitting the micro price facts requires very large idiosyncratic shocks and implies large movements in micro quantities.

PDFCombining Forecasts From Nested Models
By Todd E. Clark and Michael W. McCracken
RWP 06-02, March 2006; updated September 2008
Motivated by the common finding that linear autoregressive models often forecast better than models that incorporate additional information, this paper presents analytical, Monte Carlo, and empirical evidence on the effectiveness of combining forecasts from nested models. In our analytics, the unrestricted model is true, but a subset of the coefficients are treated as being local-to-zero. This approach captures the practical reality that the predictive content of variables of interest is often low. We derive MSE-minimizing weights for combining the restricted and unrestricted forecasts. Monte Carlo and empirical analyses verify the practical effectiveness of our combination approach.

PDFNet Exports, Consumption Volatility and International Real Business Cycle Models
By Andrea Raffo
RWP 06-01, March 2006
Conventional two-country RBC models interpret countercyclical net exports as reflecting, in large part, the dynamics of capital. I show that, quantitatively, theoretical economies rely on counterfactual terms of trade effects: trade fluctuations, on the contrary, are driven primarily by consumption smoothing, thus generating procyclical net trade in goods. I then consider a class of preferences that embeds home production in a reduced form: consumption volatility increases so that countercyclical net exports reflect primarily a strong relation between income and imports, as in the data. The major discrepancy between theory and data concerns the variability of international prices.
