This paper presents an econometric mediation analysis. It considers identification of production functions and the sources of output effects (treatment effects) from experimental interventions when some inputs are mismeasured and others are entirely omitted. JEL Code: D24, C21, C43, C38.

We propose a model to study the role of industry-level external economies scale in open economies. If elasticity governing strength is below inverse trade each industry, then specialization under frictionless consistent with comparative advantage, tractable even frictions, and all countries gain from trade. External lower gains except if country specializes industries high economies, they ampli...

This paper discusses those sources of endogenous growth arising from labor as labor. It uses a production function which models the returns to scale as a function of the division of labor and learning. Smithian analysis of the labor process constitutes the basis upon which we build our own approach. © 2001 Elsevier Science B.V. All rights reserved. JEL classification: D24; J24; O41

How does rural-urban migration shape urban production in developing countries? We use longitudinal data on Chinese manufacturing firms between 2000 and 2006, exploit exogenous variation induced by agricultural income shocks for identification. find that, when immigration increases, becomes more labor intensive productivity declines. investigate the reorganization of using patent applications pr...

We study how opening to trade affects economic growth in a model where heterogeneous firms can adopt new technologies already use by other their home country. characterize the rate using summary statistic of profit distribution: mean-min ratio. Opening increases spread through increased export opportunities and foreign competition, induces more rapid technology adoption, generates faster growth...

Innovation plays a crucial role in improving firm's performance. The relationship between innovation and productivity has been widely analysed during this decade across countries industries, generating important new findings. This study aims to provide an overall literature review on the of firms obtain comprehensive overview changing productivity. By reviewing existing empirical evidence, one ...

Factor market failures can limit adoption of profitable technologies. We leverage a plot-level spatial regression discontinuity design in the context irrigation use by farmers provided free access to water. Using boosts profits 43–62 percent. Yet, only irrigate 30 percent plots because labor costs. demonstrate inefficient use, showing irrigating one plot reduce their on other plots. This ineffi...

This paper studies the interaction between barriers to firm entry and distortions allocative efficiency in a standard model of dynamics. We derive strategy infer based on cross-country differences size distribution idiosyncratic distortions. The inferred resemble regulation-based indicators advanced economies but are substantially higher middle- low-income countries. Regulation-based cannot acc...
