Evolutionary economics emerged in the late twentieth century as a heterodox response to the limitations of neoclassical theory. Richard R. Nelson, together with Sidney G. Winter, pioneered this approach in An Evolutionary Theory of Economic Change (1982), offering a dynamic framework for understanding innovation, firm behaviour, and institutional development. Their work remains central to the study of technological change and long-run growth.
Read MoreThe Coase Theorem occupies a central place in modern economic thought, reshaping how scholars and policymakers understand externalities, property rights, and the role of government intervention. Named after the British economist Ronald H. Coase, it originated in his landmark article The Problem of Social Cost (1960), which has become one of the most cited works in the history of economics. Coase’s insight was both deceptively simple and radically transformative: under certain conditions, private bargaining between individuals can solve problems of externalities without the need for state intervention. This challenged the then-dominant Pigovian framework, which emphasised taxes and subsidies to internalise external costs and benefits.

Read MoreThe intellectual contribution of Arthur Cecil Pigou (1877–1959) to economics has been enduring, particularly through his development of welfare economics and his insights into externalities. Pigou’s work laid the foundations for modern public economics, especially the study of how government intervention can address market failures and improve social welfare. His thinking, often referred to as Pigovian or Pigou economics, emerged from a period of transition in economic theory, as the discipline moved away from the classical preoccupation with production and distribution towards the neoclassical analysis of welfare and efficiency.
