ABSTRACT
We use firm-level data from a Colombian manufacturing survey, complemented with data from the tax department, to test the effect of firms’ total tax and contribution rate (TCR) on the ratio of innovation expenditures to sales. We construct a data panel from 2003 to 2018 comprising 104,762 observations and implement fixed effects and instrumental variables estimation methods. Our results suggest that an increase of one percentage point in direct taxation leads to a decrease of 0.10% in the probability that firms engage in innovation investments, and market power moderates this effect. We discuss distinctive features of the effect of taxation on innovation in emerging economies—one being the inability of local innovation clusters to temper it. Policy implications include considering modifications to the magnitude and composition of the TCR as an alternative to R&D tax credits.

3 With the exception of two studies of Chinese firms discussed below. It must be noted however that in many aspects the Chinese case differs greatly from that of the rest of developing countries.
4 Inclusion parameters are having over 10 workers and 180,000 USD of production value (at 2016 prices).
5 The World Bank’s Total Tax and Contribution Rate measures ‘the amount of taxes and mandatory contributions payable by businesses after accounting for allowable deductions and exemptions as a share of commercial profits. Taxes withheld (such as personal income tax) or collected and remitted to tax authorities (such as value added taxes, sales taxes or goods and service taxes) are excluded.'
6 Other estimates disagree with the World Bank figure and find a lower rate after applying all the discounts and the effect of avoidance and evasion. However, they all agree on overall high corporate tax burden (see Olivera (Citation1996), Cardenas and Mercer (Citation2005), Avila and Leon (Citation2008), ANDI (Citation2014), Gomez and Steiner (Citation2015), Avila-Mahecha (Citation2015)).
