Alfred Marshall – The Father of Modern Microeconomics

  Welcome back to the blog! Today we explore the life and legacy of Alfred Marshall (1842–1924) , the British economist who laid the foundations of modern microeconomics . His landmark book, Principles of Economics (1890), introduced core concepts like supply and demand , elasticity , and market equilibrium — ideas that continue to shape how we understand economics today.

He believed economics should be rigorous, mathematical, and practical , focusing on real-world issues like prices, wages, and consumer behavior. Marshall also emphasized that economics is ultimately about improving human well-being. Key Contributions 1.

Behavioral Portfolio Theory (BPT) – Rethinking Investor Behavior and Portfolio Construction

  Traditional finance theories like Modern Portfolio Theory (MPT) assume that investors are perfectly rational and risk-averse, aiming to maximize utility by optimizing expected returns and variance. However, decades of research in behavioral finance have shown that investors often deviate from purely rational behavior. Behavioral Portfolio Theory (BPT) , introduced by Shefrin and Statman in 2000, offers a fresh perspective by integrating psychological and emotional factors into portfolio construction. What is Behavioral Portfolio Theory? Behavioral Portfolio Theory suggests that investors mentally segment their wealth into multiple “mental accounts” or layers, each with distinct goals, risk preferences, and expectations. Unlike MPT's single-layer approach focusing on an overall risk-return tradeoff, BPT models the portfolio as a layered pyramid , where each layer reflects different investor aspirations. For example: The bottom layer prioritizes capital preservation and safe...
