Abstract
Purpose
The main aim of this study is to investigate the effects of marketing and costs and research and development (R&D) investments on profitability of pharmaceutical companies of Iran.
Design/methodology/approach
In this study, pharmaceutical companies that have been accepted in Tehran Stock Exchange until March 19, 2013 were investigated. Random-effect panel data estimator was used for this purpose.
Findings
The findings indicate that variables such as company size, capital-to-total asset ratio and debt-to-asset ratio have an effect on profitability. But, company life, advertising cost and R&D investment are ineffective on profitability.
Originality/value
Legal issues like not having patent law and pricing mechanism are reasons for the ineffective relationship between R&D and marketing costs and its effect on profitability of the Iran pharmaceutical industry.
