Do R&D expenditures really matter for TFP?

Abstract: Recently, several studies have emphasized the role of R&D expenditure in determining Total Factor Productivity (TFP). In this paper it is shown that the relationship between R&D variables and TFP is far from being established. In particular, by using data for the Italian economy, it is found that the estimated effects of R&D variables on TFP crucially depends on: (i) the way in which the production function, used to derive Solow residuals, is defined; (ii) the numbers of maintained hypotheses used to estimate … Show more

“…Nevertheless, through an application to the Italian economy, Atella and Quintieri (2001) show that this relationship depend on the measures of Solow´s residual and on the aggregation level of the analysis. [ Figure 2]…”

“…This is because of using Solow model assumptions [37] (constant returns to scale, competitive market, and not short run fixities) can produce biased residuals as is mentioned by Atella and Quintieri [4] and Coe and Helpman [10]. Moreover, based on the conclusions of Swaine [38], the economic growth in the USA corresponds to an endogenous process since he found a structural change in the trend of the per-capita income which is "inconsistent with an exogenous growth assumption, but consistent with endogenous growth.…”

“…In the context of endogenous growth models, Atella & Quintieri (2001) puts in check the consummate relationship between R&D variables with the TFP. Using an Italian case study, the authors showed that R&D effects on TPF depend on: (1) the way in which the production function is defined; (2) the number of assumptions used to estimate Solow residues; (3) the level of aggregation of the data used for the empirical analysis.…”
