Aggregate Productivity Growth: Lessons from Microeconomic Evidence
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

Evaluating the Impact of Cluster Development Programs
TL;DR: In this article, the authors offer an insight into the methods that can help answer these fundamental questions through solid quantitative evidence, such as the level of coordination that is achieved and the actions undertaken as a result of improved coordination and strategy-setting of the relevant actors.

Small Business vulnerability to floods and the effects of disaster loans
TL;DR: In this paper, the authors examine the impacts of floods on businesses and the efficacy of small business administration (SBA) disaster loans on mitigating disaster aftereffects and find lack of business adaptation to extreme events in the short term, indicating their extreme vulnerability to flood disasters.

Cross-Sectoral Variation in Firm-Level Idiosyncratic Risk
TL;DR: This paper found that idiosyncratic risk accounts for about 90% of the overall uncertainty faced by firms and that firms in the most volatile sector are subject to at least three times as much uncertainty as those in the least volatile.

A Model of Growth Through Creative Destruction

TL;DR: In this paper, a model of endogenous growth is developed in which vertical innovations, generated by a competitive research sector, constitute the underlying source of growth and equilibrium is determined by a forward-looking difference equation, according to which the amount of research in any period depends upon the expected amount of the research next period.

The Dynamics Of Productivity In The Telecommunications Equipment Industry
George S Olley,Ariel Pakes +1 more
TL;DR: In this article, the authors developed an estimation algorithm that takes into account the relationship between productivity on the one hand, and both input demand and survival on the other, guided by a dynamic equilibrium model that generates the exit and input demand equations needed to correct for the simultaneity and selection problems.
