The Alpha Beta Gamma of the Labor Market
Using a large panel dataset of US workers, we calibrate a search-theoretic model of the labor market, where workers are heterogeneous with respect to the parameters governing their employment transitions. We first approximate heterogeneity with a discrete number of latent types, and then calibrate type-specific parameters by matching type-specific moments. Heterogeneity is well approximated by 3 types: αs, βs and γs. Workers of type α find employment quickly because they have large gains from trade, and stick to their jobs because their productivity is similar across jobs. Workers of type ...

Nowcasting Business Cycles: a Bayesian Approach to Dynamic Heterogeneous Factor Models
We develop a framework for measuring and monitoring business cycles in real time. Following a long tradition in macroeconometrics, inference is based on a variety of indicators of economic activity, treated as imperfect measures of an underlying index of business cycle conditions. We extend existing approaches by permitting for heterogenous lead-lag patterns of the various indicators along the business cycles. The framework is well suited for high-frequency monitoring of current economic conditions in real time - nowcasting - since inference can be conducted in presence of mixed frequency ...

Measuring Geopolitical Risk
We present a news-based measure of adverse geopolitical events and associated risks. The geopolitical risk (GPR) index spikes around the two world wars, at the beginning of the Korean War, during the Cuban Missile Crisis, and after 9/11. Higher geopolitical risk foreshadows lower investment and employment and is associated with higher disaster probability and larger downside risks. The adverse consequences of the GPR index are driven by both the threat and the realization of adverse geopolitical events. We complement our aggregate measures with industry- and firm-level indicators of ...

How Should Unemployment Insurance Vary over the Business Cycle?
We study optimal unemployment insurance (UI) over the business cycle using a heterogeneous agent job search model with aggregate risk and incomplete markets. We validate the model-implied micro and macro labor market elasticities to changes in UI generosity against existing estimates, and provide an explanation for divergent empirical findings. We show that generating the observed demographic differences between UI recipients and non-recipients is critical in determining the magnitudes of these elasticities. We find that the optimal policy features countercyclical replacement rates with ...

Cross-Sectional Financial Conditions, Business Cycles and The Lending Channel
I document business cycle properties of the full cross-sectional distributions of U.S. stock returns and credit spreads from financial and nonfinancial firms. The skewness of returns of financial firms (SRF) best predicts economic activity, while being a barometer for lending conditions. SRF also affects firm-level investment beyond firms' balance sheets, and adverse SRF shocks lead to macroeconomic downturns with tighter lending conditions in vector autoregressions (VARs). These results are consistent with a lending channel in which cross-sectional financial firms' balance sheets play a ...

Firm Dynamics and the Origins of Aggregate Fluctuations
What drives aggregate fluctuations? I test the granular hypothesis, according to which the largest firms in the economy drive aggregate dynamics, by estimating a dynamic factor model with firm-level data and controlling for the propagation of firm-level shocks using multi-firm growth model. Each time series, the growth rate of sales of a specific firm, is decomposed in an unobserved common macroeconomic component and in a residual that I interpret as an idiosyncratic firm-level component. The empirical results suggest that, once I control for aggregate shocks, idiosyncratic shocks do not ...

Accounting for Productivity Dispersion over the Business Cycle
This paper presents accounting decompositions of changes in aggregate labor and capital productivity. Our simplest decomposition breaks changes in an aggregate productivity ratio into two components: A mean component, which captures common changes to firm factor productivity ratios, and a dispersion component, which captures changes in the variance and higher order moments of their distribution. In standard models with heterogeneous firms and frictions to firm input decisions, the dispersion component is a function of changes in the second and higher moments of the log of marginal revenue ...

Firm Wages in a Frictional Labor Market
This paper studies a labor market with directed search, where multi-worker firms follow a firm wage policy: They pay equally productive workers the same. The policy reduces wages, due to the influence of firms? existing workers on their wage setting problem, increasing the profitability of hiring. It also introduces a time-inconsistency into the dynamic firm problem, because firms face a less elastic labor supply in the short run. To consider outcomes when firms reoptimize each period, I study Markov perfect equilibria, proposing a tractable solution approach based on standard Euler ...

What Inventory Behavior Tells Us About How Business Cycles Have Changed
Beginning in the mid-1980s, the nature of U.S. business cycles changed in important ways, as made evident by distinctive shifts in the comovement and relative volatilities of key economic aggregates. These include labor productivity, hours, output, and inventories. Unlike the widely documented change in absolute volatility over that period, known as the Great Moderation, these shifts in comovement and relative volatilities persist into the Great Recession. To understand these changes, we exploit the fact that inventory data are informative about sources of business cycles. Specifically, they ...

A Search-Based Neoclassical Model of Capital Reallocation
As a form of investment, the importance of capital reallocation between firms has been increasing over time, with the purchase of used capital accounting for 25% to 40% of firms total investment nowadays. Cross- firm reallocation of used capital also exhibits intriguing business-cycle properties, such as (i) the illiquidity of used capital is countercyclical (or the quantity of used capital reallocation across rms is procyclical), (ii) the prices of used capital are procyclical and more so than those of new capital goods, and (iii) the dispersion of firms' TFP or MPK (or the bene t of capital ...
