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. Who Was Alfred Marshall? Alfred Marshall was a professor at the University of Cambridge and a key figure in the development of neoclassical economics . 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. Supply and Demand Analysis Marshall was the first to clearly present supply and demand as intersecting curves on a graph. He showed how prices are determined by both what consumers are willing to pay (dem...

“This Sentence Is False”: The Liar Paradox, from Ancient Crete to Modern Code

 “All Cretans are liars,” said the Cretan Epimenides.  “This sentence is false,” echoes every logic textbook.  We’re still arguing 2,600 years later—and the paradox is winning.   _____________________________  /                             \ |   “THIS SENTENCE IS FALSE.”  |  \_____________________________/               |               |  self-reference               v    +---------------------------+    |  Truth flips back on     |    |  itself — paradox loop!  |    +---------------------------+ 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...
