Investment
An asset or object that is bought with the hope of making money or seeing its value increase is considered an investment. Investments are often meant to increase wealth or provide a safety net in case of unforeseen circumstances.
This paper's goal is to give a thorough overview of investment, determinants of investment, categories, the marginal efficiency of investment, and the marginal efficiency of capital.
Stocks, bonds, mutual funds, exchange-traded funds, real estate, and precious metals are among the most popular investment categories. These assets can be held through a broker or purchased and sold on the stock market.
For generations, investing has been a well-liked method of making money. The earliest evidence of investment is from prehistoric Mesopotamia when people bought cattle and agricultural land.
Investment refers to the acquisition of stocks, bonds, equities, and debentures. According to Say's law of investment, income is typically used for consumption. Overproduction may occur when a portion of revenue is not used for consumption or saved. However, the rate of interest is a key factor in determining how much money consumers and producers should save and invest. The amount that should be saved and invested depends on the interest rate. The market equilibrium rate of interest at which the equality between saving and investment is restored and there is no overproduction is determined by the interaction of demand for and supply of saving as capital.
In the long run, employment may be increased by increasing investment rates rather than using shelf adjustment mechanisms, according to Keynes. He didn't believe in the long term or in the idea that we would all survive it. Keynes claims that it is merely a financial investment and not a genuine investment. The stock of the country's real capital does increase as a result of this kind of investment. Keynes believed that investment included paying for capital investments.
Real investment is the addition of tangible capital to the stock. Capital additions include the purchase of new machinery, structures, tools, equipment, etc. All businesses must invest money in new equipment, machinery, and other items that must be replaced when they become worn out. If businesses want to expand and stay on the cutting edge of technology, they need to raise more money. Additionally, businesses maintain inventories of raw materials, semi-finished items, and finished goods.
Three key factors drive companies to hold stocks:
- To ensure a smooth production process, raw materials must be stored in adequate amounts.
- Holding stock allows businesses to meet an unforeseen rise in demand for the finished good.
- Purchasing and holding raw materials in stockpiles is an option if a future rise in the raw material is expected.
Capital:
When talking about investments, the word capital is used.
What does the word "capital" mean?
Depending on the context, the term "capital" can refer to a range of things, including financial capital (cash or other assets that can be used to generate revenue), human capital (a person's skills, knowledge, and experience), and social capital (the networks and connections that a person or organization has). Capital is frequently used in the context of business and economics to refer to financial assets like cash, real estate, or machinery that can be utilized to generate income.
Investing in machinery, tools, and equipment for businesses to use in the ongoing creation of goods and services is known as a business investment.
Residential investment is the cost of building or purchasing new homes or apartments for living in or renting to others.
Investment in inventory includes stock of raw materials, semi-finished items, and finished goods.
Determinants of Investment
According to classical economists, there are three determinants of investment. They are cost, return, and expectation.
- As investment expenses rise in response to an increase in the interest rate, businesses are compelled to save money since doing so yields higher returns. Due to lower investment costs, businesses are more motivated to invest money when interest rates are low. Conversely, saving money is less appealing as a result of the lower interest rates.
- Business confidence, sometimes known as the "animal spirit," is a metric that assesses how optimistic organizations are.
- Due to the circular flow of income, consumer and business confidence are directly or indirectly correlated. Businesses are more inclined to invest when there are more demands.
- Due to businesses' ability to offer goods at higher prices, inflation boosts investment.
- Deflation reduces investment because the cost of products has gone down on average.
- As businesses invest to adapt to new, more effective technology, investment rises.
- Because the government gets a higher portion of the money from business taxes, investment declines.
- Investment decreases when inventories or unsold commodities rise.
- Businesses are less inclined to invest if there is excess capacity, whereas businesses are more likely to invest if there isn't excess capacity.
- Consumption habits, population expansion, bank financing options, governmental policies, and other factors influence investment.
Investment Categories
1. Gross investment and net investment:
The gross investment, which includes the depreciation value, is the total amount spent on new capital goods within a year. Any sector's investment will not always be utilized to boost production. Instead, a portion of it will go toward maintaining and repairing dated and malfunctioning machinery and apparatus. All outlays are referred to as gross investments. Deducting depreciation from the gross investment will yield the net investment.
Net investment plus depreciation equals gross investment.
i.e. NI = GI - Depreciation
2. Induced investment and Autonomous Investment
The cost of purchasing fixed assets and stocks that are necessary when the level of income and demand in an economy rises is known as "induced investment." Induced investment is driven by financial gain. It is connected to shifts in national income. The national income and induced investment have a positive relationship; as the national income declines, induced investment also declines, and vice versa. An investment that is induced is income elastic. It slopes positively. I = f(Y)
Induced investment is classified as :
- Average Investment Propensity API = I/Y
- Marginal propensity to invest (MPI) = Change in I/ Change in Y where I is investment and Y is income.
Construction of roads, bridges, schools and charitable homes are a few examples of investments that are not reliant on national income and are mostly undertaken with the welfare of the community in mind rather than for financial gain. These investments are crucial for lifting the country out of depression and are not impacted by increases in labor costs or raw material prices.
3. Private Investment and Public Investment
Private investment refers to funds put into a company by you, your friends, family, and other individuals. It can be either equity or debt (money lent to a corporation) (money invested in exchange for shares). Private investors seek a return on their investment, which often comes from either dividend given by the company or a growth in the value of their shares. If the marginal efficiency is greater than the interest rate, then private investment increases. Because there is no assurance that you will receive your money back, private investments carry a higher level of risk than investments made on the public market. However, if you make wise choices, it may also be quite profitable!
Public investment is the term for the government's spending on assets that are meant to last longer than a year. Investments are made in research and development, hospitals, canals, education, and infrastructure. Public investment can also be divided into current and capital categories. Spending for current public investment includes costs associated with running the government daily, such as paying staff members' salaries at hospitals or schools. Building new facilities or purchasing equipment like computers for a long period are examples of capital public investment.
4. Ex-ante Investment and Ex-post Investment
Ex-ante is Latin for "before the event." Ex-ante investments are ones that a company undertakes without any knowledge of potential future market conditions. Ex-ante investments are those that are made based on predictions of future events rather than real past happenings.
Ex-post means following the event. Ex-post investments are those that a company makes following the observation or experience of certain actual market situations, such as changes in demand, cost, etc. Ex-post investments are those that are based on real past events as opposed to anticipated future ones.
Marginal Efficiency of Capital
The marginal efficiency of capital (MEC) is a concept in economics that refers to the expected rate of return on an additional unit of capital. The marginal efficiency of capital (MEC) is also known as the marginal rate of return on capital or the marginal product of capital. It is used to evaluate the profitability of potential investments and to determine the optimal level of investment for a business or economy.
MEC is usually measured as the ratio of the additional income generated by an additional unit of capital to the cost of that unit of capital. For example, if an additional unit of capital costs $100 and generates an additional $110 in income, the MEC would be 110/100 = 1.1 or 110%. This means that for every dollar invested, an additional $1.10 is generated in income.
The MEC is determined by the expected revenue from an investment minus the expected costs, divided by the cost of the investment. A high MEC indicates that an investment is expected to be highly profitable, while a low MEC suggests that it may not be as profitable.
The formula to calculate the marginal efficiency of capital (MEC) is:
MEC = (Expected Revenue - Expected Costs) / Additional Capital Investment
It's important to note that the MEC is a rate, often expressed as a percentage, so the result of the above formula should be multiplied by 100.
Expected revenue and expected costs are the projected future cash flows from the investment. It is important to note that the MEC is a forward-looking concept, it represents the expected rate of return over the lifetime of the investment, not the historical or current rate of return.
It should also be noted that the MEC is a subjective measure and it can vary depending on the investment, the individual or organization evaluating the investment, and the specific conditions of the market and economy.
MEC is an important concept in macroeconomic theory, as it plays a key role in determining the optimal level of investment, which in turn affects economic growth and the overall level of employment and income in an economy.
It is typically represented as a downward-sloping curve on a graph, with the X-axis representing the amount of capital invested and the Y-axis representing the expected rate of return. The slope of the curve represents the rate at which the expected return decreases as more capital is invested.
Why MEC curve shifts upward?
The marginal efficiency of capital (MEC) curve can shift upward for a few reasons. Some of the most common reasons include:
Increase in expected future returns: If investors expect higher returns from future investments, the MEC curve will shift upward as the rate of return on capital investments will be higher. This can happen due to an increase in demand for goods and services, or an increase in the productivity of capital.
Decrease in risk: If the perceived risk of capital investments decreases, the MEC curve will shift upward. For example, if a new technology is introduced that makes capital investments less risky, the MEC will increase.
Increase in technology: Advancements in technology can increase the productivity of capital, making investments more profitable and the MEC will shift upward.
Lower interest rate: Lower interest rate environment makes borrowing cheaper, thus increasing the expected returns of investment and the MEC will shift upward.
Government policies: Government policies such as tax incentives, subsidies, grants, and other forms of support can increase the profitability of capital investments, shifting the MEC curve upward.
It's worth noting that the MEC curve is a theoretical construct and its movements may not always align with real-world investment behavior.
Marginal Efficiency of Investment:
The marginal efficiency of investment (MEI) is an economic concept that refers to the expected return on an additional unit of investment. It is typically represented as a downward-sloping curve on a graph, with the x-axis representing the amount of investment and the y-axis representing the expected rate of return. The slope of the curve represents the rate at which the expected return decreases as more investment is made. The MEI is an important concept in macroeconomics and investment analysis as it helps to determine the optimal level of investment in an economy. The MEI is closely related to the marginal efficiency of capital (MEC) which is the expected return on an additional unit of capital investment.
Factors on which MEC depends:
The marginal efficiency of capital (MEC) depends on a variety of factors, including:
The capital asset's prospective yields: Prospective yield, also known as expected yield, is the expected return on an investment that is projected to be earned in the future. In other terms, the total net return anticipated from a capital asset over the course of its lifetime is its prospective yield.
It is a projection or estimate of the income that an investment will generate and is used to evaluate the potential profitability of the investment.
Capital asset's supply price:
The supply price of capital assets refers to the cost of acquiring an additional unit of capital. This can include the purchase price of the capital, as well as any ongoing costs associated with maintaining or operating the capital.
The level of investment: As the level of investment increases, the MEC will tend to decrease as the returns on additional units of capital decrease.
The rate of interest: The MEC is inversely related to the rate of interest, meaning that as the rate of interest increases, the MEC will decrease, and vice versa. This is because a higher rate of interest makes borrowing more expensive and reduces the profitability of investments.
The state of technology: The MEC depends on the state of technology as new technologies can increase the productivity and profitability of investments.
The state of the economy: The MEC depends on the state of the economy, as a robust economy will generate more investment opportunities and higher returns than a weak economy.
The level of risk: The MEC depends on the level of risk associated with an investment, as investments with higher risk typically have higher expected returns.
The expectations of future economic developments: The MEC is a forward-looking concept, so the expectations of future economic developments are also important factors, such as inflation and GDP growth.
The availability of capital: The MEC also depends on the availability of capital, as a shortage of capital will decrease the MEC, and an abundance of capital will increase the MEC.
The investment's life span: The MEC also depends on the investment's life span, as longer life span projects will have a lower MEC than shorter life span projects.
How do entrepreneurs make an estimate for investment?
An entrepreneur can use prospective yield and supply price to make an estimate for an investment. The prospective yield is the expected return on an investment that is projected to be earned in the future and supply price is the cost of acquiring an additional unit of capital.
Here's a general process that an entrepreneur can use to make an estimate for an investment using prospective yield and supply price:
Identify the investment opportunity: The entrepreneur should research and analyze the market to identify potential investment opportunities that align with their business goals and objectives.
Project future cash flows: The entrepreneur should estimate the future cash flows that the investment is expected to generate. This can be done by forecasting revenue and expenses for the investment.
Calculate the prospective yield: The entrepreneur can calculate the prospective yield by taking the expected future cash flows from the investment and dividing them by the initial cost of the investment.
Evaluate the supply price: The entrepreneur should estimate the cost of acquiring an additional unit of capital, which includes the purchase price of the capital, as well as any ongoing costs associated with maintaining or operating the capital.
Compare the prospective yield and supply price: The entrepreneur can compare the prospective yield to the supply price to evaluate the profitability of the investment. If the prospective yield is greater than the supply price, the investment may be considered profitable.
Assess other factors: The entrepreneur should also consider other factors such as risk, liquidity, and the competition before making a final decision on whether to invest or not.
It's worth noting that this process is an estimation and that the actual results may differ from the estimated ones. Entrepreneurs should also be aware of the uncertainty that often comes with forecasting future cash flows and market conditions.
Overall, it's important to note that the MEC is a complex concept, and it can vary depending on the investment, the individual or organization evaluating the investment, and the specific conditions of the market and economy.
The practice of investing involves putting money into something with the hope of receiving a return on that investment. This can take the shape of securities, such as stocks, bonds, property, or a variety of other items. Investment has a long and complex history, with several schools of thought emerging at various points.
The most crucial thing to keep in mind regarding investing is that it carries risk. There is no assurance that your investment will provide a profit; in fact, it's possible that you could even lose money. This is why it's crucial to understand investing well before investing any money. In conclusion, investing is a difficult and hazardous process, but if done properly, it can be quite profitable. Make sure you do your research and are aware of the hazards if you are considering investing.
