A Paper on Equity Risk Premium - Risk and Reward Model

This research paper explores the concept of Equity Risk Premium (ERP) which is the additional return investors expect for investing in equities over risk-free assets. The study examines the theoretical foundations of ERP, its role in investment decision-making, and its importance in company valuation and capital allocation.

Drawing on historical market data, valuation principles, and academic research, the paper analyzes the key drivers of Equity Risk Premium, how it changes across economic cycles, and its application in estimating the Cost of Equity through valuation models such as CAPM. The research further investigates how investor sentiment, macroeconomic conditions, and market expectations influence ERP and, consequently, asset prices.

This paper aims to bridge the gap between financial theory and real-world market behavior, providing investors, students, and finance professionals with a practical understanding of one of the most important inputs in valuation and investment analysis.
