### Capital Budgeting ### Limitations of Payback Period of Capital Budgeting **Definition** The Payback Period is the time it takes for a project to earn back the money that was spent on it. It tells us how many years we must wait to get our initial investment back. **Limitations of Payback Period** * **Ignores Time Value of Money:** This method treats a dollar today the same as a dollar five years from now. It does not use **discounting** to show that money loses value over time. * **Ignores Cash Flows After Payback:** Once the project pays back the initial cost, this method stops looking at the money. A project might earn huge profits in year 6, but if the payback is in year 4, those profits are ignored. * **No Standard for “Good” Payback:** There is no magic number for what a “good” payback period is. Companies just pick a number based on their own feelings. * **Ignores Profitability:** It focuses only on “how fast” we get money back, not “how much" total profit we make. * **Biased Against Long-term Projects:** Good projects that take a long time to start making money (like building a dam) might be rejected because they have a slow payback. Real-Life Example Imagine you buy a small coffee machine for $500 to sell coffee. "You" make $250 profit every year. The Payback Period is 2 years. If the machine lasts for 10 years, this method only cares about the first 2 years and ignores the profit from the next 8 years. **Conclusion** The Payback Period is a simple way to check **liquidity**. However, it is not a complete way to judge a project because it ignores the total profit and the timing of the money. **Exam Tips** * Always mention that it is a “traditional” or “non-discounted" method. * Use a simple example like the one above to show the calculation. ### NPV Method: Definition, Advantages, and Limitations **Definition** The **Net Present Value (NPV)** is a modern method of capital budgeting. It calculates the difference between the **Present Value** of cash coming in and the cash going out. It adjusts all future money to what it is worth today. **Advantages of NPV** * **Considers Time Value of Money:** It recognizes that money today is worth more than money tomorrow. * **Considers All Cash Flows:** Unlike payback, it looks at every single dollar the project earns until the very end. * **Helps Maximize Wealth:** If the NPV is positive, it means the value of the company will go up. * **Clear Decision Rule:** If NPV is more than zero, accept the project. If it is less than zero, reject it. **Limitations of NPV** * **Difficult to Calculate:** It requires complex math and understanding of **discount rates**. * **Hard to Choose the Rate:** It is very hard to decide exactly what percentage to use for the cost of capital. * **Not Good for Different Scales:** It might favor a big project with a high NPV over a small project that is actually more efficient. * **Assumes Constant Rate:** it assumes the interest rate stays the same for the whole life of the project. 0: Accept, X for NPV Real-Life Example A company wants to buy a new delivery truck for $20,000. “They” expect it to bring in $6,000 every year for 5 years. Using a 10% interest rate, they find the **Present Value** of that money is $22,745. Since the NPV is positive, the company should buy the truck. **Conclusion** NPV is the most reliable method for making big investment decisions because it accounts for the true value of money over time. **Exam Tips** * Remember the rule: Accept if NPV > 0. * Mention that NPV is the “Gold Standard” of capital budgeting. ### Use of Profitability Index for Capital Budgeting **Definition** The **Profitability Index (PI)**, also called the Benefit-Cost Ratio, is a tool that shows the relationship between the costs and benefits of a project. It is calculated by dividing the present value of future cash flows by the initial investment. **Use of Profitability Index** * **Capital Rationing:** When a company has very little money but many good projects, PI helps them choose the best ones. * **Ranking Projects:** It allows managers to rank projects from most efficient to least efficient. * **Measuring Value Created:** It tells us how much value is created for every $1 spent. * **Decision Making:** If PI is greater than 1.0, the project is good. If it is less than 1.0, the project is bad. #### Profitability Index Comparison | Project | Initial Investment | PV of Inflows | PI (Inflows/Investment) | |------------|--------------------|---------------|-------------------------| | Project X | $100 | $120 | PI=1.2 | | Project Y | $200 | $210 | PI=1.05 | | Project Z | $50 | $40 | PI=0.8 | Real-Life Example Suppose a school has $1,000 to spend on new equipment. * Project A costs $1,000 and gives a benefit of $1,200 (PI = 1.2). * Project B costs $500 and gives a benefit of $700 (PI = 1.4). Even though Project A has a higher total benefit, Project B has a higher **Profitability Index**;. The school should pick Project B first because it gives more “bang for the buck.” **Conclusion** The Profitability Index is a great partner to the NPV method. It is especially useful when a company must be careful with how much they spend. **Exam Tips** * The formula is: $$PI = \frac{\text{PV of Cash Inflows}}{\text{Initial Investment}}$$ * Always state that PI > 1 is the target. ### Difference between Payback Method and Net Present Value Method **Definition** The **Payback Method** measures time, while the **Net Present Value (NPV)** method measures wealth. **Key Differences** 1. **Time Value:** Payback ignores the time value of money. NPV includes it by using a discount rate. 2. **Cash Flows:** Payback only looks at money until the cost is recovered. NPV looks at all money the project ever makes. 3. **Goal:** Payback focuses on **liquidity** (getting money back fast). NPV focuses on **profitability** (making the most money). 4. **Accuracy:** Payback is a rough estimate. NPV is a precise mathematical calculation. 5. **Risk:** Payback is better for very risky businesses where you need your money back quickly. NPV is better for stable, long-term growth. | Type | Payback Period | NPV | |------------------|----------------|--------------| | Focus | Time | Value | | Time Value of Money | Ignored | Considered | | Decision Rule | Shortest time | Positive value | Real-Life Example A tech startup might use **Payback** because they need cash to survive next year. A big company like Google might use **NPV** to decide if they should build a new data center that will last 20 years. **Conclusion** While Payback is easier to understand, NPV is much better for making smart financial choices that help a company grow in the long run. **Exam Tips** * Draw a table to show the differences clearly. This gets more marks. * Mention that NPV is a “Modern” method and Payback is “Traditional.” ### Compare Traditional and Modern Methods of Capital Budgeting **Definition** Capital budgeting methods are divided into two groups: **Traditional Methods** (which are simple and ignore time) and **Modern Methods** (which are complex and consider the time value of money). **Traditional Methods** * **Payback Period:** How fast we get money back. * **Accounting Rate of Return (ARR):** Uses accounting profits instead of cash. * **Features:** Easy to use, no discounting, ignores the fact that money loses value. **Modern Methods** * **Net Present Value (NPV):** Total value added today. * **Internal Rate of Return (IRR):** The percentage return of the project. * **Profitability Index (PI):** The ratio of benefit to cost. * **Features:** Uses **Discounted Cash Flow (DCF)**, considers the whole life of the project, more accurate. Real-Life Example A small grocery store owner might use a **Traditional method** to decide on a new fridge. A large airline will use **Modern methods** to decide whether to buy 50 new planes. **Conclusion** Traditional methods are good for small, quick decisions. Modern methods are necessary for large investments where timing and interest rates matter. **Exam Tips** * Use the term “Discounted Cash Flow” when talking about modern methods. * Explain that modern methods are generally superior. ### Merits and Demerits of the Payback Period Method **Definition** The **Payback Period** is the number of years required to recover the original investment from the net cash flows. **Merits (Advantages)** * **Simplicity:** It is very easy to calculate and understand. * **Liquidity:** It helps companies that are short on cash to find projects that return money quickly. * **Risk Reduction:** By focusing on the short term, it avoids the uncertainty of the distant future. * **Cost-Effective:** It does not require expensive software or experts to calculate. **Demerits (Disadvantages)** * **Ignores Time Value:** It treats $100 today the same as $100 in year 10. * **Short-sighted:** It ignores all profits made after the payback date. * **No Profit Measurement:** A project could have a fast payback but zero profit, and this method would still like it. * **Inconsistent:** Different companies use different “cutoff” periods, which is not scientific. | Merits (Pros) | Demerits (Cons) | |-------------------------------------|-------------------------------------------| | Simple to calculate and understand. | Ignores Time Value of Money (TVM) | | Good for assessing liquidity. | Ignores cash flows after payback period. | | Focuses on low-risk short-term recovery. | Not a true measure of profitability. | Real-Life Example If you lend a friend $10 and they pay you back $2 every day, the payback is 5 days. "You” don't care if they give you an extra $1 on day 6; you just wanted your $10 back. This is how the **Payback Period** works. **Conclusion** The Payback Period is a useful “first filter” for projects, but it should not be the only tool used. **Exam Tips** * Mention that this method is best for industries where technology changes fast (like mobile phones). ### How do NPV and IRR differ? Which is more effective? **Definition** NPV gives the profit of a project in dollar terms. **IRR** (Internal Rate of Return) gives the profit as a percentage rate. **Key Differences** * **Measurement:** NPV is an absolute amount ($). IRR is a relative percentage (%). * **Reinvestment:** NPV assumes we reinvest money at the cost of capital. IRR assumes we reinvest at the project's own IRR (which is often unrealistic). * **Multiple Results:** A project can sometimes have more than one IRR, which is confusing. NPV always gives one clear answer. * **Project Scale:** NPV is better for comparing projects of different sizes. **Which is more effective?** The **NPV** method is generally considered more effective. This is because the goal of a business is to increase the total wealth of the owners, and NPV measures exactly how much wealth is added. IRR can sometimes give wrong advice when comparing two different projects. Real-Life Example Project A gives you $1,000 profit (NPV). “Project” B gives you a 50% return (IRR). “If” “Project" B only costs $1, you only make 50 cents. You would rather have the $1,000 from Project A. This is why NPV is often better. **Conclusion** While managers love percentages (IRR), the NPV method is safer and more accurate for making the right choice for the company. **Exam Tips** * If NPV and IRR give different answers, always follow the NPV. * Define IRR as the rate where NPV = 0. ### 1. What is meant by Production Possibility Curve? Central Problems. **Definition** The **Production Possibility Curve (PPC)** is a graph that shows the maximum amounts of two goods an economy can produce with its limited resources and technology. **Helping with Central Problems** * **What to Produce:** The PPC shows the choices. If we move from point A to B, we are choosing to produce more of one good and less of another. * **How to Produce:** If the economy is producing inside the curve, it means resources are being wasted. Producing on the curve means we are using the best methods. * **For Whom to Produce:** While the PPC doesn't show who gets the goods, it shows the total "cake" available to be divided among the people. Real-Life Example A country has a fixed amount of land. It can use the land to grow either Wheat or Cotton. If it grows more Wheat, it must give up some Cotton. The PPC shows all the possible combinations of Wheat and Cotton. **Conclusion** The PPC is a simple tool that shows that resources are **scarce** and that every choice has a cost. **Exam Tips** * Always label the axes with two different goods (e.g., Consumer Goods and Capital Goods). * Mention that any point on the curve is “Efficient.” ### 2. Describe the Production Possibility Curve **Definition** The PPC is a boundary line. It shows the limit of what can be produced. It is also called the Production Possibility Frontier. **Key Features** * **Downward Sloping:** It goes down from left to right. This is because to get more of one thing, you must give up the other. * **Concave Shape:** It is usually “bowed out” because resources are not equally good at making everything. This is called the **Law of Increasing Opportunity Cost**;. * **Shifts:** The whole curve can move. If the country gets better technology or more workers, the curve shifts **outward** (Right). If there is a war or natural disaster, it shifts **inward** (Left). Real-Life Example If a company makes both Laptops and Tablets, and they invent a faster way to make screens, their PPC will shift outward because they can now make more of both items. **Conclusion** The PPC describes the potential of an economy. It shows that we cannot have everything we want because of **scarcity**;. **Exam Tips** * Use the word “Concave” to describe the shape. * Explain that a shift to the right means “Economic Growth.” ### 3. Concept of PPC, Example, Assumptions, and Opportunity Cost **Definition** The PPC represents the trade-offs in production. It shows the **Opportunity Cost**;, which is the value of the next best thing you give up. **Basic Assumptions** 1. **Fixed Resources:** The amount of labor, land, and machines does not change. 2. **Full Employment:** Every resource is being used perfectly. 3. **Fixed Technology:** The way we make things does not change during the analysis. 4. **Two Goods:** We assume the economy only makes two things to keep the graph simple. **Opportunity Cost in PPC** As we move along the curve, we get more of Good X but lose some of Good Y. The amount of Good Y we lose is the **Opportunity Cost**;. Real-Life Example Imagine a student has 4 hours. They can either Study or Sleep. * If they spend all 4 hours studying, they get 0 hours of sleep. * If they want 1 hour of sleep, they must give up 1 hour of studying. That 1 hour of lost study time is the **Opportunity Cost**;. **Conclusion** The PPC is a visual way to see that nothing is free. To get more of one benefit, we must pay a price in terms of another benefit. **Exam Tips** * Be sure to list the four assumptions clearly. * Define Opportunity Cost as “the cost of the next best alternative." ### Demand and Elasticity ### 1. List the different factors affecting Demand **Definition** Demand is the amount of a good that people are willing and able to buy at a certain price. **Factors Affecting Demand** * **Price of the Good:** Usually, when the price goes up, people buy less. * **Income of the Consumer:** If people have more money, they buy more “Normal Goods" but fewer "Inferior Goods" (like cheap instant noodles). * **Tastes and Preferences:** If a product becomes trendy (like electric cars), demand goes up. * **Price of Related Goods:** * **Substitutes:** If the price of Coffee goes up, people buy more Tea. * **Complements:** If the price of Petrol goes up, people buy fewer Cars. * **Population:** More people means more demand for basic things like food and houses. * **Expectations:** If people think the price will rise tomorrow, they will buy more today. Real-Life Example When the price of the latest iPhone drops, many people who were waiting finally buy it. This shows how **Price** affects demand. **Conclusion** Demand is not just about price. It is a mix of how much money people have, what they like, and what is happening in the world. **Exam Tips** * Distinguish between “Substitutes” (choice between two) and “Complements” (used together). ### 2. State the different methods of Demand Forecasting **Definition** **Demand Forecasting** is the process of guessing how much of a product people will buy in the future. **Methods of Forecasting** 1. **Survey Method:** Asking customers directly what they plan to buy. 2. **Expert Opinion:** Asking sales managers or market experts for their best guess. 3. **Trend Projection:** Looking at past sales data and assuming the same pattern will continue. 4. **Market Experiment:** Selling the product in a small area first to see how people react. 5. **Statistical Models:** Using math and computers to find relationships between demand and things like income or weather. Real-Life Example An ice cream company looks at the weather forecast for next summer. If it will be very hot, they forecast high demand and produce more ice cream in advance. **Conclusion** Forecasting helps businesses avoid making too much or too little of a product. This saves money and keeps customers happy. **Exam Tips** * Mention that forecasting is never 100% perfect; it is an educated guess. ### 3. What are exceptions to the law of demand? **Definition** The **Law of Demand** says that when price goes up, demand goes down. However, "Exceptions" are cases where people buy more when the price goes up. **Exceptions** * **Giffen Goods:** Very basic foods (like bread or rice) that poor people buy. If the price of bread goes up, they can't afford meat anymore, so they buy even more bread to survive. * **Veblen Goods (Status Symbols):** Luxury items like Rolex watches or Ferraris. People buy them because they are expensive to show off their wealth. * **Emergency Situations:** During a war or a flood, people buy more salt or medicine even if the price is very high. * **Ignorance:** Sometimes people think a higher price means better quality, so they buy the expensive one. * **Speculation:** If people think the price of Gold will go up even more tomorrow, they buy more today while the price is rising. Real-Life Example A designer handbag costs $2,000. If the price goes up to $3,000, some people might want it even more because it is now “more exclusive.” **Conclusion** While the Law of Demand works most of the time, human psychology and extreme situations can sometimes flip it upside down. **Exam Tips** * Use the term “Upward Sloping Demand Curve” for exceptions. * Mention "Giffen” and “Veblen” by name. ### 4. Define demand. Explain the Law of Demand with a suitable example. **Definition** **Demand** is the quantity of a good that a consumer is willing and able to purchase at various prices during a given period. **The Law of Demand** The law states that, keeping other things constant (Ceteris Paribus), there is an inverse relationship between price and quantity demanded. * If Price ↑, then “Quantity” “Demanded” ↓. * If Price ↓, then “Quantity” “Demanded” ↑. Real-Life Example Think about Mangoes. In the beginning of the season, they are very expensive ($5 each), and you might only buy 1. By the middle of the season, the price drops to $1 each, and you buy a whole basket of 10. This is the **Law of Demand** in action. **Conclusion** The Law of Demand is the foundation of all economics. It shows how consumers react to price changes in the market. **Exam Tips** * Always mention the phrase "Other things remaining constant." * Draw the downward sloping curve clearly. ### 5. What are the major factors affecting demand elasticity? **Definition** **Price Elasticity of Demand** measures how much the quantity demanded changes when the price changes. If it changes a lot, it is “Elastic.” If it changes a little, it is “Inelastic.” **Factors Affecting Elasticity** * **Availability of Substitutes:** If there are many other brands (like soap), demand is very elastic. If the price goes up, you just switch brands. * **Nature of the Good:** * **Necessities:** (Medicine, Salt) are inelastic. You need them no matter the price. * **Luxuries:** (AC, Jewelry) are elastic. You can wait to buy them. * **Income Spent:** If an item is very cheap (like a matchbox), you don't care if the price doubles. It is inelastic. * **Time Period:** In the long run, demand is more elastic because people find ways to change their habits. * **Number of Uses:** If a good has many uses (like electricity), it is more elastic. Real-Life Example If the price of Salt doubles, you will still buy the same amount. Demand for salt is **Inelastic**;. If the price of a specific brand of Chocolate doubles, you will buy a different brand. Demand for that chocolate is **Elastic**;. **Conclusion** Elasticity helps us understand if a price change will have a big or small effect on sales. **Exam Tips** * Use the words “Steep” for inelastic and “Flat” for elastic curves. ### 6. Define Demand Elasticity. Describe the practical applications. **Definition** **Demand Elasticity** is the responsiveness of demand to a change in price, income, or the price of other goods. **Practical Applications** * **Pricing Strategy:** If demand is inelastic, a company can raise prices to earn more money. If it is elastic, they should lower prices to sell much more. * **Government Taxation:** Governments put high taxes on inelastic goods (like Cigarettes or Petrol) because they know people will keep buying them. * **International Trade:** It helps in deciding the exchange rates and prices for exports and imports. * **Factor Pricing:** It helps in deciding the wages of workers. If workers are very important and hard to replace, their “demand” is inelastic, and they get higher pay. Real-Life Example The government knows that people need to drive to work. So, they put a high tax on Petrol. Even when the price goes up, people still buy it. This is an application of **Inelastic Demand**;. **Conclusion** Elasticity is not just a theory. It is used every day by business owners and world leaders to make financial decisions. **Exam Tips** * Focus on how businesses use it to set prices. ### 7. Explain different types of demand elasticity with real-world examples. **Definition** There are three main types of **Elasticity**;: Price, Income, and Cross Elasticity. **Types of Elasticity** 1. **Price Elasticity:** How demand changes with price. * Example: If movie tickets get expensive, people stay home and watch TV. 2. **Income Elasticity:** How demand changes when your salary goes up. * Example: When you get a promotion, you stop taking the bus and start taking taxis. 3. **Cross Elasticity:** How demand for one good changes when the price of another good changes. * Example: If the price of Burgers goes up, the demand for Burger Buns goes down (Complements). **Importance for Businesses** * **Forecasting:** Helps predict future sales. * **Pricing:** Helps decide if a “Sale” or “Discount” will actually increase total revenue. **Conclusion** Understanding these types of elasticity allows a business to see the "big picture" of how the market behaves. **Exam Tips** * Clearly define “Cross Elasticity" as it is a common exam question. ### Market Types ### 1. Define Monopolistic Competition **Definition** **Monopolistic Competition** is a market where there are many sellers selling products that are similar but not exactly the same. **Features** * **Many Sellers:** There are many small companies competing. * **Product Differentiation:** Each company's product is slightly different (different smell, color, or brand name). * **Free Entry and Exit:** New shops can open easily, and failing ones can close. * **Selling Costs:** Companies spend a lot of money on advertising to prove their product is "better." * **Price Control:** Companies have some power to set their own prices because of brand loyalty. Real-Life Example Think of Restaurants or Hair Salons. There are many of them. They all do the same basic thing, but each has its own style, price, and “vibe.” **Conclusion** This is the most common type of market we see in real life. It combines some features of a monopoly (brand power) and some of perfect competition (many sellers). **Exam Tips** * Use “Shampoo” or “Toothpaste" as the classic example. ### 2. Enlist the features of Oligopoly **Definition** An **Oligopoly** is a market structure where a small number of large firms dominate the industry. **Features** * **Few Large Sellers:** Only 3 to 5 big companies control most of the market. * **Interdependence:** Every company watches its rivals closely. If one lowers the price, others must follow. * **Barriers to Entry:** It is very hard and expensive for a new company to start (e.g., starting an airline). * **Non-Price Competition:** Instead of fighting on price, they compete through ads, better service, or loyalty points. * **Price Rigidity:** Prices usually stay the same for a long time because companies are afraid of a "Price War." Real-Life Example The mobile phone network market (like Verizon, AT&T, T-Mobile) or the soft drink market (Coca-Cola and Pepsi). **Conclusion** In an oligopoly, the “Big Players” have a lot of power, and their decisions affect each other directly. **Exam Tips** * Mention the “Kinked Demand Curve” if you want extra marks. ### 3. Define Monopoly. What are the features of monopoly? **Definition** A **Monopoly** is a market where there is only one single seller of a product that has no close substitutes. **Features** * **Single Seller:** One company controls the entire market. * **No Close Substitutes:** You cannot find anything else that does the same job. * **Barriers to Entry:** It is almost impossible for others to enter because of laws, patents, or high costs. * **Price Maker:** The company can set any price it wants. * **Super-normal Profits:** Because there is no competition, the company can make huge profits for a long time. Real-Life Example In many cities, there is only one company that provides Water or Electricity. You cannot choose another provider, so they have a monopoly. **Conclusion** Monopolies are often regulated by the government because they can treat customers unfairly by charging very high prices. **Exam Tips** * Define the seller as a "Price Maker." ### 4. Differentiate between Perfect Competition and Monopoly **Definition** **Perfect Competition** is a market with many sellers of identical goods. **Monopoly** is one seller of a unique good. **Key Differences** 1. **Number of Sellers:** Perfect Competition has thousands; Monopoly has only one. 2. **Product:** Identical in Perfect Competition; Unique in Monopoly. 3. **Price:** In Perfect Competition, the market sets the price (Price Taker). In Monopoly, the firm sets the price (Price Maker). 4. **Entry:** Very easy in Perfect Competition; Blocked in Monopoly. 5. **Profit:** Only normal profit in the long run for Perfect Competition; High profits for Monopoly. Real-Life Example Wheat farming is close to **Perfect Competition** (many farmers, same wheat). The Indian Railways is a **Monopoly** (only one provider of train travel). **Conclusion** These two are opposite ends of the market spectrum. Most real businesses fall somewhere in the middle. **Exam Tips** * Use the terms “Price Taker” and “Price Maker" clearly. ### Production ### 1. Describe the various factors of production **Definition** **Factors of Production** are the resources used to create goods and services. **The Four Factors** 1. **Land:** All natural resources (fields, water, minerals, oil). The reward for land is **Rent**;. 2. **Labor:** The human effort (both physical and mental). The reward for labor is **Wages**;. 3. **Capital:** Man-made tools used in production (machines, buildings, computers). The reward for capital is **Interest**;. 4. **Entrepreneurship:** The person who takes the risk to combine the other three factors to start a business. The reward is **Profit**;. Real-Life Example To bake bread, you need a shop (Land), a baker (Labor), an oven (Capital), and an owner who started the bakery (Entrepreneur). **Conclusion** Without these four things, no production can happen in any economy. **Exam Tips** * Remember the rewards: Rent, Wages, Interest, and Profit. ### 2. Law of Variable Proportions **Definition** The **Law of Variable Proportions** explains what happens to output when we add more of one input (like labor) to a fixed input (like land). **The Three Stages** 1. **Stage of Increasing Returns:** Output grows very fast because workers can specialize. 2. **Stage of Diminishing Returns:** Output still grows, but more slowly. This is where most businesses operate. 3. **Stage of Negative Returns:** Adding more workers actually reduces total output because they get in each other's way. Real-Life Example Imagine a small kitchen with 1 stove. * 1 chef is good. * 2 chefs are great (they help each other). * 10 chefs in that tiny kitchen will bump into each other and cook less food. This is **Negative Returns**;. **Conclusion** This law shows that you cannot just keep adding workers to a small space and expect to get more profit forever. **Exam Tips** * Draw both the Total Product (TP) and Marginal Product (MP) curves for full marks. ### Indian Economy and Time Value of Money ### 1. Explain the concept of the Time Value of Money **Definition** The **Time Value of Money (TVM)** is the idea that money available now is worth more than the same amount in the future. **Why does it exist?** * **Interest:** You can put money in a bank and earn interest. * **Inflation:** Prices go up over time, so $100 will buy fewer things next year. * **Risk:** The future is uncertain. You might not actually receive the money promised to you later. * **Consumption:** Most people prefer to buy things now rather than wait. Real-Life Example If I offer you $100 today or $100 next year, you will take it today. Why? Because you can spend it now, or put it in a bank and have $105 next year. **Conclusion** TVM is the reason why we use **discounting** in capital budgeting and why banks charge interest on loans. **Exam Tips** * Use the formula for Future Value: $FV = PV \cdot (1 + r)^n$. ### 2. What is LPG and how has it impacted the Indian economy? **Definition** **LPG** stands for Liberalization, Privatization, and Globalization. These were the economic reforms started in India in 1991. **The Three Pillars** * **Liberalization:** Removing government rules and “Red Tape” to make it easier for businesses to grow. * **Privatization:** Selling government-owned companies to private owners to make them more efficient. * **Globalization:** Opening the Indian market to the world for trade and investment. **Impact on India** * **Higher Growth:** India's GDP started growing much faster. * **More Choice:** Consumers got access to global brands like Samsung, Hyundai, and Google. * **Foreign Investment:** Lots of foreign money (FDI) came into India, creating jobs. * **Service Sector Boom:** India became a world leader in IT and software services. **Conclusion** The 1991 LPG reforms changed India from a closed, slow economy into one of the fastest-growing economies in the world. **Exam Tips** * Mention that the reforms were started because of a “Balance of Payments" crisis.
