TL;DR: In this paper, the authors review some recent micro-econometric studies evaluating effects of government-sponsored commercial R&D and pay particular attention to the conceptual problems involved Neither the firms receiving support, nor those not applying, constitute random samples Furthermore, those not receiving support may be affected by the programs due to spillover effects.

TL;DR: In this paper, a parsimonious model of innovation is developed to confront firm-level evidence, which captures the dynamics of individual heterogeneous firms, describes the behavior of an industry with firm entry and exit, and delivers a general equilibrium model of technological change.

TL;DR: In this article, the inconsistency of common scale estimators when output is proxied by deflated sales, based on a common output deflator across firms is explored, and it is shown that the scale estimates tend to be downward biased in the production function case, under a wide range of assumptions about the pattern of technology, demand and factor price shocks.

TL;DR: In this paper, the inconsistency of common scale estimators when output is proxied by deflated sales, based on a common output deflator across firms, is explored, and it reveals itself as a downward bias in the scale estimates obtained from production function regressions, under a variety of assumptions about the pattern of technology, demand and factor price shocks.

TL;DR: In this paper, the authors present a new econometric framework that permits simultaneous estimation of price-cost margins, scale economies and productivity from a panel of establishment data. But the model contains only a few, economically interesting parameters to be estimated, but it is nevertheless consistent with a flexible (translog) underlying technology, quasi-fixed capital and the presence of persistent differences in productivity between establishments.
