Funds for Financing Investment

Suppose Y Y is the household’s income. Then,

Y=C+S+TY=C+S+T


Where:

C  C\; →   \; Consumption of goods and services
S  S\; →   \; Savings
T  T\; →   \; Net tax paid to the government

Recall that income Y Y is also equal to all the expenditures,

Y=C+I+G+X−MY = C + I + G + X -M


Setting the two equations equal gives us

C+I+G+X−M=C+S+TC + I + G + X - M = C + S + T

I+G+X−M=S+T I + G + X - M = S + T

I+G+X=M+S+T I + G + X = M + S + T


Subtracting G G and X X on both sides will give us investment I I .

I=S+(T−G)+(M−X) I = S + (T- G) +(M-X)


Where investment is financed by:
  1. S  S\; →   \; Savings
  2. T−G  T - G \; →   \; government budget surplus
  3. M−X  M - X \; →   \; borrowing from the rest of the world

Note: If TT > GG and MM > XX, then it contributes to financing investments.

The Real & Nominal Interest Rate

Nominal Interest Rate: the amount of dollars that borrowers pay to the lender as interest in a year expressed as a percentage of the value owed to the lender.

Example: If the annual interest paid to the lender is 10$ on a $200 loan, then the nominal interest is:

Nominal Interest Rate = 10200 ×100\frac{10} {200} \, \times 100 = 5%


Real Interest Rate: is nominal interest that is adjusted to clear the effects of inflation. In other words,

Real Interest  ≈  \, \approx \, Rate Nominal Interest Rate - Inflation Rate


Example: If the nominal interest rate is 3% and the inflation rate is 1%, then

Real Interest Rate = 3% - 1% = 2%


Real interest rate is important because we are going to see how the demand and supply of loan market determines the real interest rate, and how real interest can affect investments.


Demand & Supply of Loanable Funds

Quantity of Loanable Funds Demanded: the total quantity of funds demanded to finance investment, government budget deficit, and international investment or lending for a provided period.

We will only look at investment.

Demand for Loanable Funds Curve: is the relationship between the quantity of loanable funds demanded and the real interest rate, leaving all other influences the same.

The demand for loanable funds curve looks like the following:

Loanable Funds Market


Characteristics of demand for loanable funds curve:
  1. Downward sloping
  2. As real interest rate  ↑ \, \uparrow \, , then investment  ↓ \, \downarrow \, and quantity of funds demanded  ↓ \, \downarrow \,
  3. As real interest rate  ↓ \, \downarrow \, , then investment  ↑ \, \uparrow \, and quantity of funds demanded  ↑ \, \uparrow \,

Quantity of Loanable Funds Supplied: the total quantity of funds supplied to finance investment, government budget deficit, and international investment or lending for a provided period.

Supply for Loanable Funds Curve: is the relationship between the quantity of loanable funds supplied and the real interest rate, leaving all other influences the same.

The supply for loanable funds curve looks like the following:

Loanable Funds Market


Characteristics of supply for loanable funds curve:
  1. Upward sloping
  2. As real interest rate  ↑ \, \uparrow \, , then savings  ↑ \, \uparrow \, and quantity of funds supplied  ↑ \, \uparrow \,
  3. As real interest rate  ↓ \, \downarrow \, , then savings  ↓ \, \downarrow \, and quantity of funds supplied  ↓ \, \downarrow \,

Loanable Funds Market Equilibrium: the intersection of the demand and supply for loanable funds curve is the loanable funds market equilibrium. There is no excess or shortage of loanable funds here.

Loanable Funds Market


Depending on the real interest rate, we can have an excess or shortage of loanable funds.

Case 1: If the real interest rate is above the equilibrium interest, then there is a surplus of funds.

Loanable Funds Market


Case 2: If the real interest rate is below the equilibrium interest, then there is a shortage of funds.

Introduction to Loanable Funds Market

The loanable funds market plays a crucial role in modern economies, serving as the mechanism through which savings are channeled into investments. Our introduction video provides an essential foundation for understanding this complex topic. It illustrates how the market facilitates the flow of funds from savers to borrowers, ultimately driving economic growth. Key concepts covered in this article include the supply and demand for loanable funds, the determination of the real interest rate, and the factors influencing market equilibrium. We'll explore how various economic agents, such as households, businesses, and governments, interact within this market to finance investments and manage their financial resources. Understanding the loanable funds market is vital for grasping broader economic principles and policy implications. As we delve deeper into this subject, you'll gain insights into how interest rates are determined and how they affect investment decisions across the economy.

FAQs

  1. What is the loanable funds market?

    The loanable funds market is a conceptual market where the supply of funds available for lending meets the demand for borrowing. It represents how savings in an economy are channeled into investments. The market determines the equilibrium interest rate, which balances the amount savers are willing to lend with the amount borrowers want to borrow.

  2. How does the real interest rate differ from the nominal interest rate?

    The nominal interest rate is the stated rate of interest without accounting for inflation. The real interest rate, on the other hand, is adjusted for inflation and represents the actual cost of borrowing or return on savings in terms of purchasing power. To calculate the real interest rate, you subtract the inflation rate from the nominal interest rate.

  3. What factors influence the demand for loanable funds?

    Several factors influence the demand for loanable funds, including investment opportunities, business expansion needs, consumer confidence, economic conditions, and government policies. When there are profitable investment opportunities or businesses are looking to expand, the demand for loanable funds typically increases. Economic growth and favorable government policies can also boost demand.

  4. How does the supply of loanable funds respond to changes in interest rates?

    The supply of loanable funds generally increases as interest rates rise. This is because higher interest rates incentivize saving and lending, as individuals and institutions can earn greater returns on their savings. Conversely, when interest rates are low, the supply of loanable funds tends to decrease as there's less incentive to save or lend money.

  5. What happens when there's a surplus or shortage in the loanable funds market?

    A surplus occurs when the quantity of funds supplied exceeds the quantity demanded at the current interest rate. This puts downward pressure on interest rates. A shortage happens when the quantity demanded exceeds the quantity supplied, pushing interest rates upward. In both cases, market forces work to restore equilibrium by adjusting the interest rate until supply and demand are balanced.

Prerequisites

Understanding the loanable funds market is crucial for grasping the dynamics of financial systems and economic decision-making. However, to fully comprehend this complex topic, it's essential to have a solid foundation in certain prerequisite concepts. One of the most important prerequisites is market equilibrium in economics, which plays a pivotal role in shaping our understanding of the loanable funds market.

The concept of market equilibrium is fundamental to analyzing the loanable funds market. In essence, the loanable funds market represents the interaction between savers (suppliers of funds) and borrowers (demanders of funds) in an economy. Just as in any other market, the loanable funds market seeks to achieve a balance between supply and demand, which is where market equilibrium comes into play.

When studying market equilibrium, students learn about the forces that drive prices and quantities to a point where supply equals demand. This principle directly applies to the loanable funds market, where the "price" is the interest rate, and the "quantity" is the amount of funds lent or borrowed. Understanding how equilibrium is reached in a general market context provides the necessary framework for analyzing the specific dynamics of the loanable funds market.

Moreover, the concept of market equilibrium helps explain how changes in various factors can affect the loanable funds market. For instance, shifts in saving behavior, investment opportunities, or government policies can all impact the supply and demand for loanable funds. By applying the principles of market equilibrium, students can predict and interpret these changes, gaining valuable insights into the functioning of financial markets and the broader economy.

Additionally, understanding market equilibrium is crucial for grasping the role of interest rates in the loanable funds market. Interest rates act as the price mechanism that brings the supply and demand for loanable funds into balance. Students who have a solid grasp of how prices adjust to achieve equilibrium in general markets will find it easier to comprehend the similar process in the loanable funds market, where interest rates fluctuate to equilibrate saving and borrowing.

In conclusion, a thorough understanding of market equilibrium in economics is essential for students approaching the study of the loanable funds market. It provides the necessary analytical tools and conceptual framework to explore the complexities of financial markets, interest rate determination, and the allocation of capital in an economy. By mastering this prerequisite topic, students will be better equipped to navigate the intricacies of the loanable funds market and its broader economic implications.
