Labor productivity: structural change and cyclical dynamics
A longstanding puzzle of empirical economics is that average labor productivity declines during recessions and increases during booms. This paper provides a framework to assess the empirical importance of competing hypotheses for explaining the observed procyclicality. For each competing hypothesis we derive the implications for cyclical productivity conditional on expectations of future demand and supply conditions. The novelty of the paper is that we exploit the tremendous heterogeneity in long-run structural changes across individual plants to identify the short-run sources of procyclical ...

Euler-equation estimation for discrete choice models: a capital accumulation application
This paper studies capital adjustment at the establishment level. Our goal is to characterize capital adjustment costs, which are important for understanding both the dynamics of aggregate investment and the impact of various policies on capital accumulation. Our estimation strategy searches for parameters that minimize ex post errors in an Euler equation. This strategy is quite common in models for which adjustment occurs in each period. Here, we extend that logic to the estimation of parameters of dynamic optimization problems in which non-convexities lead to extended periods of investment ...

High tech business entry in the pandemic era
The COVID-19 pandemic and its aftermath have featured a surge in business entry (Decker and Haltiwanger 2024). A natural question is whether the elevated entry seen in recent years will have positive implications for aggregate productivity growth given the historically important role of business entry for productivity dynamics (Decker et al. 2014, Alon et al. 2018).

Dynamics of labor demand : evidence from plant-level observations and aggregate implications
This paper studies the dynamics of labor demand at the micro and aggregate level. The correlation of hours and employment growth is negative at the plant level and positive in aggregate time series. Further, hours and employment growth are about equally volatile at the plant level while hours growth is much less volatile than employment growth in the aggregate data. Given these differences, we specify and estimate the parameters of a plant-level dynamic optimization problem using simulated method of moments to match plant-level observations. Our findings indicate that non-convex adjustment ...

Measuring Early-Stage Business Formation
New businesses play an important role in overall economic activity. They account for a sizable share of job creation, and they provide a key source of innovation that contributes to overall productivity growth.

Job Displacement and Job Mobility: The Role of Joblessness
Who is harmed by and who benefits from worker reallocation? We investigate the earnings consequences of changing jobs and find a wide dispersion in outcomes. This dispersion is driven not by whether the worker was displaced, but by the duration of joblessness between job spells. Job movers who experience joblessness suffer a persistent reduction in earnings and tend to move to lower-paying firms, suggesting that job ladder models offer a useful lens through which to understand the negative consequences of job separations.

Job-to-Job Flows and the Consequences of Job Separations
A substantial empirical literature documents large and persistent average earnings losses following job displacement. Our paper extends the literature on displaced workers by providing a comprehensive picture of earnings and employment outcomes for all workers who separate. We show that for workers not recalled to their previous employer, earnings losses follow separations in general, as opposed to displacements in particular. The key predictor of earnings losses is not displacement but the length of the nonemployment spell following job separation. Moreover, displaced workers are no more ...

Early-Stage Business Formation : An Analysis of Applications for Employer Identification Numbers
This paper reports on the development and analysis of a newly constructed dataset on the early stages of business formation. The data are based on applications for Employer Identification Numbers (EINs) submitted in the United States, known as IRS Form SS-4 filings. The goal of the research is to develop high-frequency indicators of business formation at the national, state, and local levels. The analysis indicates that EIN applications provide forward-looking and very timely information on business formation. The signal of business formation provided by counts of applications is improved by ...
