Background
The Required Rate of Return (RRR) is a central concept in finance, representing the mimimum return an investor expects to achieve by investing in a particular asset. This rate accounts for the risk associated with the investment, the time value of money, and potentially the opportunity cost of forgone investments.
Historical Context
The idea of a required rate of return stems from early investment theories and practices, evolving significantly with modern financial principles. Historically, investors have always sought to understand and quantify the potential returns of their investments compared to their risks, but a formal framework has been developed mainly since the mid-20th century with the emergence of financial economics.
Definitions and Concepts
The minimum rate of return on an investment needed to make it acceptable to a business. It considers several factors, including the investment’s risk, the risk-free rate of return, and any premiums for assuming additional risk. It’s used to assess potential investments and decide if they meet a firm’s threshold.
Major Analytical Frameworks
Classical Economics
Classical economics often didn’t explicitly consider investment risk in the modern sense, focusing more on capital accumulation and interest rates as key components of economic growth.
Neoclassical Economics
Neoclassical economics begins to integrate the concept of risk-adjusted returns, exploring how investors make decisions to maximize utility. It incorporates the time value of money and begins to link interest rates with required returns.
Keynesian Economics
Keynesian economics doesn’t directly address the required rate of return, but its emphasis on investment as a driver of aggregate demand plays a role in understanding how investors might decide on acceptable returns.
Marxian Economics
From a Marxian perspective, the required rate of return may take on a different meaning, often focusing on the exploitation and redistribution of surplus value, although not directly investing in financial terms.
Institutional Economics
Institutional economics would highlight how societal norms, regulations, and laws shape the required rate of return by modifying risk factors and investment parameters through market structures and rules.
Behavioral Economics
Behavioral economics explores how psychological factors impact investor expectations for returns. It considers how irrational behaviors and biases might skew perceptions of what a “required” rate of return actually is.
Post-Keynesian Economics
Post-Keynesian economics view investment in terms of social and historical context, exploring how expectations of future profitability might influence the internally considered required rate of return.
Austrian Economics
Austrian economics would approach the required rate of return through the lens of individual time preferences and opportunity costs, emphasizing subjective valuation and the role of entrepreneurial judgment.
Development Economics
In development economics, the required rate of return is critical for understanding the feasibility of investments in less developed markets, considering factors like higher risk and potential for substantial changes in growth rates.
Monetarism
Monetarism, with its focus on money supply and inflation, influences the risk-free rate, which serves as a baseline for evaluating the required rate of return on investments.
Comparative Analysis
Examining the required rate of return across various schools of thought reveals different priorities: from classical focuses on growth and accumulation to modern considerations of risk adjustment and behavioral influences.
