The ins and arounds in the U.S. housing market

In the United States, 15 percent of households change residence in a given year. This result is based on data from the Panel Study of Income Dynamics on gross flows within and between the two segments of the housing market-renter-occupied properties and owner-occupied properties. The gross flows between these two segments are four times larger than the net flows. From a secular perspective, housing turnover exhibits a hump-shaped pattern between 1970 and 2000, which this paper attributes to changes in the age composition of the U.S. population. At higher frequencies, housing turnover is procyclical and tends to lead the business cycle and real house prices. By taking a two-segment view of the U.S. housing market and by carefully documenting the empirics of turnover within and between these segments, the paper provides important moments for and gives empirical guidance to the design, calibration, and evaluation of micro-founded, dynamic, and quantitative models of the U.S. housing market

Systematic Monetary Policy and the Macroeconomic Effects of Shifts in Loan-to-Value Ratios

What are the macroeconomic consequences of changes in residential mortgage market loan-to-value (LTV) ratios? In a structural VAR, real GDP and business investment increase significantly following an expansionary LTV shock. The impact on residential investment, however, is contingent on the systematic reaction of monetary policy. Historically, the FED responded directly to lower collateral requirements by significantly raising the policy instrument, thereby increasing mortgage rates and reducing residential investment. In a counterfactual policy experiment, where the Federal Funds rate remains constant after the shock, the reaction of non-residential GDP components is magnified and residential investment increases significantly. While firms increase their borrowing after a relaxation of bank lending standards, whether monetary policy reacts endogenously or is held constant, household debt only increases in an environment of a counterfactually constant Federal Funds rate

Cyclical and sectoral transitions in the US housing market

Using data from the Panel Study of Income Dynamics, this paper examines the flow of U.S. households within and between two distinct segments of the housing market - renter-occupied properties and owner-occupied properties. The paper provides relevant empirical moments for microfounded models of the housing sector. In particular, net flows in the housing market are substantially smaller than the gross flows, as is the case in the literature on labor market flows. Housing market turnover also exhibits substantial heterogeneity in household moving rates, the long-run moving trends, and the cyclical patterns of household moving decisions. Moves by renters tend to lead movements in real GDP, while moves by homeowners are procyclical and/or slightly lag the cycle. The paper further shows that the secular decline in household moves over time is driven by reduced within-sector moves. Taken together, the paper's results imply that models aiming to describe housing market flows will have to feature substantial nonlinearities and/or multiple sector-specific (owner versus renter) shocks

Uncertainty Business Cycles - Really?

Are fluctuations in firms’ profitability risk a major cause of regular business cycles? We study this question within the framework of a heterogeneous-firm dynamic stochastic general equilibrium model with fixed capital adjustment costs. In such a model, surprise increases of risk lead to a wait-and-see policy for investment at the firm level and a decrease in aggregate economic activity. We calibrate the model using German firm-level data with a broader sectoral, size and ownership coverage than comparable U.S. data sets. The use of these data enables us to provide robust lower and upper bound estimates for the size of firm-level risk fluctuations. We find that time-varying firm-level risk on its own is unlikely to be a major quantitative source of regular business cycle fluctuations. When we augment a model with only aggregate productivity shocks by time-varying risk, the risk shocks dampen the high contemporaneous correlations of the productivity-shock-only model, but do not alter the other unconditional business cycle properties.

Investment Dispersion and the Business Cycle

We document a new business cycle fact: the cross-sectional standard deviation of firm-level investment (investment dispersion) is robustly and significantly procyclical. This makes investment dispersion different from the dispersion of productivity and output growth, which is countercyclical. Investment dispersion is more procyclical in the goods-producing sectors, for smaller firms and for structures. We show that a heterogeneous-firm real business cycle model with countercyclical idiosyncratic firm risk and non-convex adjustment costs calibrated to match moments of the long-run investment rate distribution, produces a time series correlation coefficient between investment dispersion and aggregate output of 0.58, close to the 0.45 in the data. We argue, more generally, that cross-sectional business cycle dynamics impose tight empirical restrictions on the physical environments and the structural parameters of heterogeneous-firm models.

Confidence and the Transmission of Government Spending Shocks

There seems to be a widespread belief among economists, policy-makers, and members of the media that the "confidence'" of households and businesses is a critical component in the transmission of fiscal policy shocks into economic activity. We take this proposition to the data using standard structural VARs with government spending and aggregate output augmented to include empirical measures of consumer or business confidence. We also estimate non-linear VAR specifications to allow for differential impacts of government spending in "normal'' times versus recessions. In normal times confidence does not react significantly to unexpected increases in government spending and spending multipliers are in the neighborhood of one; during recessions confidence rises and spending multipliers are significantly larger. We then quantify the importance of the systematic response of confidence to spending shocks for the spending multiplier and find that, in normal times, confidence is irrelevant for the transmission of government spending shocks to output, but during periods of economic slack it is important. We argue and present evidence that it is not confidence per se – in the sense of pure sentiment – that matters for the transmission of spending shocks during downturns, but rather that the composition of spending during a downtown is different. In particular, spending shocks during downturns predict future productivity improvements through a persistent increase in government investment relative to consumption, which is in turn reflected in higher measured confidence.

Time-varying business volatility, price setting, and the real effects of monetary policy

Does time-varying business volatility affect the price setting of firms and thus the transmission of monetary policy into the real economy? To address this question, we estimate from the firm-level micro data of the German IFO Business Climate Survey the impact of idiosyncratic volatility on the price setting behavior of firms. In a second step, we use a calibrated New Keynesian business cycle model to gauge the effects of time-varying volatility on the transmission of monetary policy to output. Our results are twofold. Heightened business volatility increases the probability of a price change, though the effect is small: the tripling of volatility during the recession of 08/09 caused the average quarterly likelihood of a price change to increase from 31.6% to 32.3%. Second, the effects of this increase in volatility on monetary policy are also small; the initial effect of a 25 basis point monetary policy shock to output declines from 0.347% to 0.341%

Cyclicality of Job and Worker Flows: New Data and a New Set of Stylized Facts

We study the relationship between cyclical job and worker flows at the plant level using a new data set spanning from 1976-2006. We find that procyclical labor demand explains relatively little of procyclical worker flows. Instead, all plants in the employment growth distribution increase their worker turnover during booms. We also find that cyclical changes in the employment growth distribution are mostly driven by plants moving from inactivity to a growing labor force during booms. Consequently, increased labor turnover at growing plants is the main quantitative driver behind increased labor turnover during booms. We argue that on the job search models are able to capture non-parallel shifts in the employment growth distribution and procyclical conditional worker flows for a range of the growth distribution. Yet, they fail to rationalize procyclical accession rates for all shrinking and procylical separation rates for all growing plants

Worker churn in the cross section and over time: New evidence from Germany

Worker churn is procyclical in the German labor market. We study the plant-level connection of churn and employment growth using the new Administrative Wage and Labor Market Flow Panel from 1975 to 2014. Churn is V-shaped in employment growth. Through analyzing this pattern by worker skill, age, and tenure, we establish that churn is unlikely to result from plant reorganization but rather from uncertainty about match quality. In a dynamic labor demand framework with a time-to-hire friction, churn can be interpreted as a manifestation of idiosyncratically stochastic separation shocks. These shocks become larger and more predictable during booms, leading to procyclical churn.The research leading to these results has received funding from the European Research Council under the European Union’s Seventh Framework Programme (FTP/2007-2013) / ERC Grant agreement no. 282740.
