Competition, R&D and innovation in Chilean firms

Purpose The purpose of this paper is to analyze the effect of competition on both innovation inputs and outputs in Chilean firms. More specifically, the authors investigate whether there is an inverted-U relationship at different stages of the innovation process. Design/methodology/approach The sample covers 1,347 firms that responded to both the 4th Chilean Longitudinal Enterprise Survey and the 10th Chilean Innovation Survey. The CDM model (Crepon et al., 1998) is applied to correct for selectivity bias and endogeneity. Competition is proxied by measures of market concentration. The robustness of the results is checked using four alternative indicators. Findings The results strongly suggest that competition and both R&D and innovation intensities are linked by an inverted U-shaped curve. The estimated effects of competition on innovation output and labor productivity are rather ambiguous. Thus, market structure would be influencing the firms' incentives to innovate, but not necessarily their innovation performance. Research limitations/implications - The model is based on cross-sectional data, hampering the possibility to control for unobserved heterogeneity. Competitive pressures from potential entrants and foreign markets are not captured in the analysis. Practical implications - Moderate levels of competition would be the optimal market structure in terms of promotingmore business R&D and innovation spending. Originality/value A previously unutilized data set covering the whole economy is used. Estimations are executed at three different stages of the innovation process. Two types of innovation input and four types of innovation output are taken into account.
