political economy within the wider geographical studies of human-environment interactions wherein economic actions of humans transform the natural environment. Apart from these, attempts have been made to develop a geographical political economy that prioritises commodity production and "spatialities" of capitalism. History documents change, often using it to argue political economy; some historical works take political economy as the narrative's frame. Ecology deals with political economy because human activity has the greatest effect upon the environment, its central concern being the environment's suitability for human activity. The ecological effects of economic activity spur research upon changing market economy incentives. Additionally and more recently, ecological theory has been used to examine economic systems as similar systems of interacting species (e.g., firms). Cultural studies examines social class, production, labor, race, gender and sex. Communications examines the institutional aspects of media and telecommunication systems. As the area of study focusing on aspects of human communication, it pays particular attention to the relationships between owners, labor, consumers, advertisers, structures of production and the state and the power relationships embedded in these relationships.
