TLDR
The authors examined the relationship between microeconomic productivity dynamics and aggregate productivity growth using establishment-level data for U.S. manufacturing establishments as well for selected service industries and found that the contribution of reallocation of outputs and inputs from less productive to more productive establishments plays a significant role in accounting for aggregate productivity.Abstract:
In this paper, we exploit establishment-level data to examine the relationship between microeconomic productivity dynamics and aggregate productivity growth. After synthesizing the evidence from recent studies, we conduct our own analysis using establishment-level data for U.S. manufacturing establishments as well for selected service industries. The use of longitudinal micro data on service sector establishments is one of the novel features of our analysis. Our main findings are summarized as follows: (i) the contribution of reallocation of outputs and inputs from less productive to more productive establishments plays a significant role in accounting for aggregate productivity growth; (ii) for the selected service industries considered, the contribution of net entry (more productive entering establishments displacing less productive exiting establishments) is dominant; (iii) the contribution of net entry to aggregate productivity growth is disproportionate and is increasing in the horizon over which the changes are measured since longer horizon yields greater differentials from selection and learning effects; (iv) the contribution of reallocation to aggregate productivity growth varies over time (e.g. is cyclically sensitive) and industries and is somewhat sensitive to subtle differences in measurement and decomposition methodologies.read more

The Impact of Uncertainty Shocks
TL;DR: In this paper, a model with a time varying second moment is proposed to simulate a macro uncertainty shock, which produces a rapid drop and rebound in aggregate output and employment, which occurs because higher uncertainty causes firms to temporarily pause their investment and hiring.

What Determines Productivity
TL;DR: The authors surveys and evaluates recent empirical work addressing the question of why businesses differ in their measured productivity levels, and lays out what I see are the major questions that research in the area should address going forward.

Reallocation, Firm Turnover, and Efficiency: Selection on Productivity or Profitability?
TL;DR: In this article, the authors investigate the nature of selection and productivity growth using data from industries where they observe producer-level quantities and prices separately, and show that there are important differences between revenue and physical productivity.

Industrial Organization and New Findings on the Turnover and Mobility of Firms
TL;DR: In this article, a large new literature derived from longitudinal data bases on the populations of firms and establishmnets in a number of countries is surveyed, showing the prevasiveness of turnover from entry and exit (high infant mortality of entrants); the entry process shows a good deal of rationality about entrants' chances and the importance of real options for entrants.

The Impact of Uncertainty Shocks

TL;DR: In this paper, a model with a time varying second moment was proposed to simulate a macro uncertainty shock, which produces a rapid drop and rebound in aggregate output and employment, and showed a good match in both magnitude and timing.

Measuring and Analyzing Aggregate Fluctuations: The Importance of Building from Microeconomic Evidence
TL;DR: The first draft of this paper was written while the author was a visiting scholar at the Kansas City Federal Reserve Bank in Summer 1996 as mentioned in this paper, and the author thanks the research staff at the KFC for providing a stimulating environment in which to think about these issues.

Firm-level Evidence on Productivity Differentials, Turnover, and Exports in Taiwanese Manufacturing
TL;DR: In this paper, the authors measured differences in total factor productivity among entering, exiting, and continuing firms, and quantified the contribution of firm turnover to industry productivity improvements, finding that the more productive members of the group, on average, survive and their productivity converges to the productivity level of incumbents.

TL;DR: In this article, the authors show how incentives assist in shaping strategy, illustrates the political costs and economic benefits of downsizing and demonstrates that even firms in declining industries have substantial opportunities for value creation.

Industry evolution with sunk costs and uncertain market conditions
TL;DR: In this paper, a dynamic competitive equilibrium framework is presented to analyze long-lasting effects of long-term decisions made by firms in a plant without knowing what market conditions will prevail during the life of the plant.
