Financial Theories

The Miller-Modigliani theorem (M&M) is one of the foundational concepts in corporate finance, challenging conventional wisdom and reshaping our understanding of capital structure. Developed by economists Franco Modigliani and Merton Miller in 1958, the theorem offers crucial insights into how a firm’s financial structure—its mix of debt and equity—affects its overall value. In this article, […]

As someone deeply immersed in finance and risk management, I find Merton’s Model of Corporate Default one of the most elegant frameworks for assessing credit risk. Developed by economist Robert C. Merton in 1974, this model applies option pricing theory to evaluate the likelihood of a firm defaulting on its debt. In this article, I

In the world of finance, the ability to assess credit risk is crucial for both lenders and investors. One of the most influential models developed for credit risk assessment is the Merton Model, named after Robert C. Merton, who introduced it in 1974. This model applies a structural approach to credit risk, treating the default

Mergers and Acquisitions (M&A) represent a critical area of corporate strategy and finance. These processes involve complex decision-making, strategic planning, and substantial financial analysis. Throughout my career, I have seen how M&A deals shape industries, create value, or, at times, fail to meet expectations. As such, understanding the theory and mechanics of M&A is crucial

Mean-variance optimization is a cornerstone of modern portfolio theory (MPT), a field developed by Harry Markowitz in the 1950s. In essence, the theory revolves around maximizing portfolio returns for a given level of risk, or conversely, minimizing risk for a given level of expected return. In this article, I will delve deep into the concepts

Financial liberalization has been a significant area of economic policy discussion for decades. The theory, introduced by economists Ronald McKinnon and Shaw, has shaped how we think about financial systems, capital markets, and economic development. At its core, McKinnon and Shaw’s theory emphasizes the importance of liberalizing financial markets to foster economic growth. However, understanding

In the landscape of modern banking, the concept of maturity transformation stands as one of the foundational theories that shape the way financial institutions operate. It lies at the heart of how banks use short-term deposits to finance long-term loans, creating liquidity and facilitating economic growth. However, it also introduces risks and challenges that, if

Introduction I first encountered Harry Markowitz’s Efficient Frontier Theory while studying portfolio optimization. The theory, introduced in his 1952 paper “Portfolio Selection,” revolutionized modern finance by quantifying the trade-off between risk and return. It laid the foundation for what we now call Modern Portfolio Theory (MPT). In this article, I break down the Efficient Frontier,

When I first encountered Markowitz Portfolio Theory, it struck me as one of those rare ideas that reshapes how we think about investing. Developed by Harry Markowitz in 1952, this theory laid the groundwork for modern portfolio management by introducing a mathematically rigorous way to balance risk and return. In this article, I will take

Introduction When I first encountered Harry Markowitz’s Mean-Variance Optimization (MVO) theory, I realized how profoundly it reshaped modern portfolio management. Before Markowitz, investors often selected stocks based on intuition or dividend yields, ignoring how assets interact. His 1952 paper, Portfolio Selection, introduced a mathematical framework to balance risk and return, laying the foundation for modern
