The analysis of rents and rent-seeking has been dominated by an economic perspective focused on assessing rents according to their impact on efficiency and economic growth. Contrary to a political approach to rent-seeking, which tends to assume the negative impact of rents and their potential to derive from corrupt activities, economists classify rents as growth-retarding or growth-enhancing. The classification of rents as “harmful” or “not harmful” does not respond to the characteristics of the different types of rents but, rather, on the conditions and incentives that make them have a positive or negative impact on the economy.
