TLDR
In this paper, an empirical focus is on estimating the parameters of a production function for the equipment industry, and then using those estimates to analyze the evolution of plant-level productivity.Abstract:
Technological change and deregulation have caused a major restructuring of the telecommunications equipment industry over the last two decades. Our empirical focus is on estimating the parameters of a production function for the equipment industry, and then using those estimates to analyze the evolution of plant-level productivity. The restructuring involved significant entry and exit and large changes in the sizes of incumbents. Firms' choices on whether to liquidate, and on input quantities should they continue, depended on their productivity. This generates a selection and a simultaneity problem when estimating production functions. Our theoretical focus is on providing an estimation algorithm which takes explicit account of these issues. We find that our algorithm produces markedly different and more plausible estimates of production function coefficients than do traditional estimation procedures. Using our estimates we find increases in the rate of aggregate productivity growth after deregulation. Since we have plant-level data we can introduce indices which delve deeper into how this productivity growth occurred. These indices indicate that productivity increases were primarily a result of a reallocation of capital towards more productive establishments.read more

Product quality and firm heterogeneity in international trade
TL;DR: The authors quantifies the separate contributions of product quality and technical efficiency in explaining variation in export outcomes across US manufacturing plants and finds substantial across-plant heterogeneity in demand, and consistent with the quality interpretation, demand is positively correlated with advertising expenditures, wage rates and material costs.

Capital Stock Approximation using Firm Level Panel Data
TL;DR: In this paper, a modified perpetual inventory approach is proposed for short firm panels, which provides more reliable measures for capital input when short firms are used and no direct information on capital input is available, and the empirical results based on a replication study of Addison et al. (2006) support the conclusion that modified perpetualinventory is superior to previous attempts in particular when fixed effects estimation techniques are used.

Foreign Acquisition and Firm Productivity: Evidence from Slovenia
TL;DR: In this paper, the impact of foreign acquisition on the productivity of Slovenian manufacturing firms subject to takeover in 1997 was investigated, and the results of the empirical analysis show no robust statistical evidence of a positive causal effect of the foreign acquisition up to two years following the takeover.

Impacts of Industry Mix, Technological Change, Selection and Plant Entry/Exit on Regional Productivity Growth
TL;DR: In this paper, Rigby et al. identified five sources of regional productivity growth: changes in industry mix, technological change by incumbent plants; selection, or changes in plant market shares; plant entry; and plant exit.
