Consequences of Rising Income Inequality
The increase in U.S. income inequality since 1970 largely reflects gains made by households in the top 20% of the income distribution. Estimates suggest that households outside this group have suffered significant losses from foregone consumption, measured relative to a scenario that holds inequality constant. A substantial mitigating factor for the losses has been the dramatic rise in government redistributive transfers, which have doubled as a share of U.S. output over the same period.

Tax structure, welfare, and the stability of equilibrium in a model of dynamic optimal fiscal policy
A demonstration that the assumed structure of taxation can have dramatic effects on economic welfare and on the stability of the steady state in a dynamic general-equilibrium model of optimal fiscal policy. The authors find that household welfare is highest under a structure that includes separate tax rates on labor and capital incomes, double taxation of dividends, and tax-deductible depreciation.

What’s different about the latest housing boom?
After peaking in 2006, the median U.S. house price fell about 30%, finally hitting bottom in late 2011. Since then, house prices have rebounded strongly and are nearly back to the pre-recession peak. However, conditions in the latest boom appear far less precarious than those in the previous episode. The current run-up exhibits a less-pronounced increase in the house price-to-rent ratio and an outright decline in the household mortgage debt-to-income ratio?a pattern that is not suggestive of a credit-fueled bubble.

Replicating Business Cycles and Asset Returns with Sentiment and Low Risk Aversion
This paper develops a real business cycle model with eight fundamental shocks andone ìequity sentiment shockî that captures belief-driven áuctuations. I solve for thetime series of shock realizations that allow the model to exactly replicate the observedtime paths of U.S. macroeconomic variables and asset returns over the past six decades.The representative agentís perception that movements in equity value are partly drivenby sentiment is close to self-fulÖlling. The model-identiÖed sentiment shock is stronglycorrelated with other fundamental shocks and implies ìpessimismîrelative to ...

House prices, credit growth, and excess volatility: implications for monetary and macroprudential policy
Progress on the question of whether policymakers should respond directly to financial variables requires a realistic economic model that captures the links between asset prices, credit expansion, and real economic activity. Standard DSGE models with fully-rational expectations have difficulty producing large swings in house prices and household debt that resemble the patterns observed in many developed countries over the past decade. We introduce excess volatility into an otherwise standard DSGE model by allowing a fraction of households to depart from fully-rational expectations. ...

Wringing the Overoptimism from FOMC Growth Forecasts
Growth forecasts by Federal Open Market Committee meeting participants were persistently too optimistic for 2008 through 2016. The typical forecast started out high but was revised down over time, often dramatically, as incoming data failed to meet expectations. In contrast, forecasts for 2017 through 2019 started low but were revised up over time. Cumulative forecast revisions for these years were much smaller on average than in the past. These observations suggest that participants have adjusted their forecast methodology, including lowering estimates of trend growth, to eliminate the prior ...

Anchored Inflation Expectations and the Slope of the Phillips Curve
We estimate a New Keynesian Phillips curve that allows for changes in the degree of anchoring of agents' subjective inflation forecasts. The estimated slope coefficient in U.S. data is stable over the period 1960 to 2019. Out-of-sample forecasts with the model resolve both the "missing disinflation puzzle" during the Great Recession and the "missing inflation puzzle" during the subsequent recovery. Using a simple New Keynesian model, we show that if agents solve a signal extraction problem to disentangle transitory versus permanent shocks to inflation, then an increase in the policy rule ...

Lock-in of extrapolative expectations in an asset pricing model
This paper examines an agent's choice of forecast method within a standard asset pricing model. To make a conditional forecast, a representative agent may choose one of the following: (1) a rational (or fundamentals-based) forecast that employs knowledge of the stochastic process governing dividends, (2) a constant forecast based on a simple long-run average of the forecast variable, or (3) a time-varying forecast that extrapolates from the last observation of the forecast variable. I show that a representative agent who is concerned about minimizing forecast errors may inadvertently become ...

Capital-labor substitution, equilibrium indeterminacy, and the cyclical behavior of labor income
This paper examines the quantitative relationship between the elasticity of capital-labor substitution and the conditions needed for equilibrium indeterminacy (and belief-driven fluctuations) in a one-sector neoclassical growth model. Our analysis employs a ?normalized? version of the CES production function so that all steady-state allocations and factor income shares are held constant as the elasticity of substitution is varied. We demonstrate numerically that higher elasticities cause the threshold degree of increasing returns for indeterminacy to decline monotonically, albeit very ...
