This paper examines the possibility of a non-linear relationship existing between intellectual property rights protection (IPR) and gross domestic product (GDP) growth rates. A theoretical justification is developed for the potential existence of a non-linear relationship in terms of a quadratic relationship. This is then examined using panel data from 191 countries and taken in 5 year intervals, although the data had many missing observations. Results indicate there is statistically significant evidence that a quadratic relationship exists between IPR and GDP growth, however there are reservations about this evidence due to a dearth of observations in countries with very weak intellectual property rights protections.
