Housing, Portfolio Choice, and the Macroeconomy

Much of the macroeconomics literature dealing with wealth distribution has become abstracted from modeling housing explicitly. This paper investigates the properties of the wealth distribution and the portfolio composition regarding housing and equity holdings and their relationship to macroeconomic shocks. To this end, I construct a business cycle model in which agents differ in age, income, and wealth and derive utility from housing services. The model is consistent with several facts such as the life-cycle pattern of housing-to-wealth ratios, the larger degree of concentration for nonhousing wealth, and the smaller weight of housing in richer households’ portfolios as well as the larger housing-to-wealth ratios in recessions. In addition, the model delivers the familiar business-cycle moments regarding relative standard deviations and procyclicality of consumption, investment, and employment.

Productivity, Energy Prices, and the Great Moderation: A New Link

We study how total factor productivity (TFP), energy prices, and the Great Moderation are linked. First we estimate a joint stochastic process for the energy price and TFP and establish that until the second quarter of 1982, energy prices negatively affected productivity. This spillover has since disappeared. Second, we show that within the framework of a dynamic stochastic general equilibrium model, the disappearance of this energy-productivity spillover generates the significantly lower volatility of output and its components. Specifically, the change in the joint stochastic process accounts for close to 70 percent of the moderation in output volatility.

Uninsurable Individual Risk and the Cyclical Behavior of Unemployment and Vacancies

This paper is concerned with the business cycle dynamics in search-and-matching models of the labor market when agents are ex post heterogeneous. We focus on wealth heterogeneity that comes as a result of imperfect opportunities to insure against idiosyncratic risk. We show that this heterogeneity implies wage rigidity relative to a complete insurance economy. The fraction of wealth-poor agents prevents real wages from falling too much in recessions since small decreases in income imply large losses in utility. Analogously, wages rise less in expansions compared with the standard model because small increases are enough for poor workers to accept job offers. This mechanism reduces the volatility of wages and increases the volatility of vacancies and unemployment. This channel can be relevant if the lack of insurance is large enough so that the fraction of agents close to the borrowing constraint is significant. However, discipline in the parameterization implies an earnings variance and persistence in the unemployment state that result in a large degree of self-insurance.

Productivity, Energy Prices and the Great Moderation: A New Link

We build upon recent research that attributes the moderation of output volatility since the 1980s to the reduced volatility of the Total Factor Productivity (TFP) by investigating the linkage between energy price fluctuations and the stochastic process for TFP. First, we estimate a joint stochastic process for the energy price and TFP and establish that until around 1982, energy prices negatively affected TFP. This spillover has since disappeared. Second, we show that within the framework of a Dynamic Stochastic General Equilibrium (DSGE) model, the disappearance of this energy-productivity spillover accounts for close to 68 percent of the moderation in output volatility.

Wages and Unemployment Across Business Cycles: A High-Frequency Investigation

This paper investigates the change in wages associated with a spell of unemployment. The novelty lies in using monthly data from the Survey of Income and Program Participation (SIPP) to analyze the dynamics of those wage changes across different business cycles. The level of education or the sector of re-employment affects the change in wages following an unemployment spell differently across different downturns. The degree of wage rigidity varies across recessions; wage changes pre- and post-unemployment are sometimes procyclical and sometimes countercyclical. These results may be useful for understanding the different aggregate employment dynamics observed across downturns and recoveries.

Comparative Advantage and Risk Premia in Labor Markets

Using the Survey of Income and Program Participation (SIPP) we estimate quarterly labor earnings risk across 21 industries of the US economy. We document a significant and positive association between earnings risk (both permanent and transitory) and average log-earnings across industries. The Finance sector is 50% riskier than Government which implies a mean earnings premium of 20%. We develop an equilibrium framework to analyze the interplay between volatility in labor earnings and comparative advantage in determining the level of earnings across industries. We use the model to decompose how much of the empirical correlation represents compensation for risk and how much represents selection. The positive association between permanent risk and earnings is compensation for risk, but selection is responsible for the observed relationship between temporary risk and mean earnings.
