In A Theory of Imperialism, the economists Utsa Patnaik and Prabhat Patnaik present a new theory of the origins and mechanics of capitalism that sounds an alarm about its ongoing viability. Their theory centers on trade between the core economies of the global North and the tropical and subtropical countries of the global South and considers how the demand for commodities (such as agricultural products and oil) from the South has perpetuated and solidified an imperialistic relationship. The Patnaiks explore the dynamics of this process and discuss innovations that could allow the economies of the South to achieve greater prosperity without damaging the economies of the North. The result is an original theory of imperialism that brings to light the crippling limitations of neoliberal capitalism.
