  • Some ways to save money and cut expenses

    Who doesn’t like to see some extra money in their savings without having to sacrifice their living standard?

    Saving is the money left after subtracting all our expenses from all our income. This is, after all, the money you can ultimately invest and grow. Well, there are two ways to save money.

    Yes, you guessed it right, either you increase your income or reduce your expenses. In this post, I will focus on the latter.

    I will share some easy ways for you to reduce your monthly expenditures, without even feeling it. While some of these may seem common sense, it is still good to read this article. Maybe, you will find one particular option, which I am going to list below.


    I am combining personal finance and human psychology with my favorite economics knowledge to come up with some doable changes we all can implement. So without further ado, let’s get into it!

    Cut Down on Streaming services

    To start with, please cancel any unnecessary online streaming subscriptions. Many times, we take too many streaming services that we don’t even use much. Honestly, on average, if you are working or studying full time, how much TV do you get to watch every day? Maybe a couple of hours, max?

    So, yes most people do not get the time to watch that much TV and we often end up paying too much for each service. So you should consider how many of these you can’t live without. Even though their monthly fees don’t seem that much individually, together they all add up.

    Is Gym membership worth it?

    Think about marginal benefit vs. marginal cost of Gym membership

    Unless you use the gym 4-5 times a week, paying $20 or so per month isn’t worth it. We get tempted by their deals and may use them for some time in the beginning, but most of us are not able to continue for whatever reason.

    I am totally in favor of exercising and maintaining a healthy lifestyle. And there are free resources for that. You can always start with walking or jogging outside or jump roping. You can also do yoga and make use of many free online exercise videos or free cardio classes. These will all give you the same results if done 3-4 times a week for 30 minutes a day.

    Do you still use Cable TV?

    How to cut your expenses without affecting your living standards?

    In a world where there are so many streaming services, I honestly think we don’t need cable TV anymore.

    I find that a lot of time is taken by the ads shown, and we don’t have the option to skip ads, in cable TV. Honestly, most people just flip between channels waiting for the ads to finish. What a waste of time!

    Consume less electricity during peak hours

    For most places, peak hours are between 4 to 9 PM. This is when you get charged the most. So try not to use your dishwashers and washers during this time if you can. Also, Having an app like Nest will help you monitor how much your AC is running and how to control it. I found some additional ways to reduce your electricity bill in this post in case you are interested.

    Refinance your loans

    If you follow my posts and the news, you must be aware that the Fed has (indirectly) raised all the interest rates that affect us. This includes our home loans as well. The Fed has clearly stated that to fight inflation, it will further raise interest rates. So there is still time for you to refinance some of your loans for a lower rate.

    So anytime, you find interest rates lower than usual, don’t miss the opportunity to refinance your mortgage.

    Eat out less

    Well, this goes without saying, right? I understand everyone can’t have a home-cooked meal every single day. We also need a break and eating out provides us with that happy feeling. But if you can, try to slowly decrease the number of times you go out to eat. For example, start by reducing it by 25% and gradually increase it.

    There will be two advantages to it. Not only you will save money on restaurant bills, but you will also be able to have a healthier life. To get to this, you will certainly need better meal planning (esp. since we all live very busy lives). Nevertheless, it is doable if you incorporate simple and healthy options to cook. One way to do it, which I sometimes do is to make extra servings of the food in an instant pot and use my freezer to save it for the future.


    Avoid instant online shopping temptations

    When we pay with credit card or debit card, often times we don’t know how much money we have spent. We easily fall prey to online shopping deals and offers. Studies have found that the pleasures of online shopping release dopamine, a happy hormone.

    Oftentimes, we just want to buy something because we see others using it. Here, we need to stop and think if we really need it. Is this really adding value to our life?

    An additional tip is while buying clothes, shoes, and accessories, try not to do too many one-time-use purchases. Buy something that you can use more often. We all need a few party wear and special occasions outfits but just choose the number wisely. We work hard for the money and we need to use our judgment while making any purchase.

    Most of the time the pleasure we get by making any purchase is very short-lived. We suffer from something called “shiny object syndrome”. So always think before giving to this instant online need to splurge. One tip is to leave the item in a shopping cart for a few days and then decide if you still need to buy it.

    Return options

    Many of the companies we buy from these days, offer return services, some up to 90 days or more with a receipt. We procrastinate returning because of this long window and may forget to return the item. I am sure it has happened to some of you. So either set up reminders or do it as quickly as you can to avoid sitting with that item.

    Be cautious of free trial magazines and other services

    Sometimes, we take a service, which is free for a trial period. Usually, these services require us to give the payment information even though they don’t charge for the trial period. They also give the option to cancel the service anytime during the trial period. But life happens and we may forget to cancel it.

    Then unknowingly, we get charged for a whole year. Be cautious of these. I would suggest not falling for these offers unless you are very disciplined and can keep track of all your free trial subscriptions. One way to avoid getting charged is to set reminders on your phone to cancel before the free trial period ends.

    So, these were some of my tips for reducing your expenses without substantially affecting your lifestyle. I am sure there are many more, so feel free to share those in the comments section below. In my other post, I will also cover some ways to increase your income.

    I hope you learned something from this personal finance post series. Please leave your comments on what type of posts you would like to read, it will help me connect with my readers more. I hope you are having an amazing day and I will be back soon with another topic. Thank you for reading till the end!

     

  • Did inflation fall to 0% in the US in July?

    Yesterday, in the news, I read President Biden saying the US had 0% inflation in July. The BLS, the official source of inflation numbers, reported no change in the CPI (Consumer price index) from June.

    So did inflation suddenly disappear? Well, it depends on how you measure it.

    Sometimes, the way politicians report some facts could give us misleading conclusions. So, the economist in me had to write something today to help my readers understand it better.

    How do we measure inflation?

    As I said above, the official inflation number in the US comes from the BLS every month. BLS calculates price inflation both monthly and annual.

    If you want to know more about inflation in simple words, you can read my previous posts. I described how we can calculate inflation using some simple examples. I also explained what policy measures the central bank takes to control inflation – my most favorite post.

    So was Biden lying when he said 0% inflation?

    There was indeed no general average price increase from June 2022 compared to July 2022. This meant a 0% monthly inflation.

    However, the year-to-year inflation ending July 2022, was 8.5%. This is still very high, compared to the average US inflation of around 2%. Inflation is the percentage price increase of a basket of goods and services people in the urban United States use. This is of course, over a specific period.

    But, the good news is that it was somewhat less than the June 2022-to-2021 inflation of 9.1%.

    A picture is worth a thousand words

    Here is a chart showing category-wise inflation. The food prices continued to rise. Few others, such as electricity, new vehicles, and shelter also rose.

    The main reason behind 0% monthly inflation was the falling gas prices. It offset the increase in food and shelter indexes. The lower gas prices finally come as a relief to millions of Americans. We have been experiencing a sharp rise in gas prices for a long time and wanted a break.

    Hopefully, Fed’s tight monetary policy will bring inflation down further in the coming months. But, there might be a cost to it- the possibility of a recession. As we say in economics, there is no free lunch. Let’s just hope that even if the R word happens, it is not significant.

  • The jobs market in the US is still going strong

    Two days ago, President Joe Biden proudly posted that the unemployment rate in the US was 3.5% in July. This matched the lowest rate in the last 50 years. He also said that since he started, 10 million jobs have been created in the US economy.

    Praising the fastest-growing job market, Biden mentioned that 528,000 jobs were added in the US in July itself. “Today, we also matched the lowest unemployment rate in America in the last 50 years: 3.5%,” he said.

    The Bureau of Labor Statistics (BLS) in the US publishes data for the unemployment and labor force statistics every month. These are based on the data collected from household surveys and establishment surveys on sample-based estimates of employment.

    I got this Civilian unemployment rate graph from the BLS. You can see that the US unemployment rate is now at its lowest level at 3.5%. This had happened three times before in Sep 2019, Jan 2020, and Feb 2020, when it hit 3.5%.

    But have you ever wondered what is the unemployment rate anyway?

    Well, the unemployment rate is the percentage of people who don’t have a job but can work and have actively looked for a job in the past 4 weeks. This is relative to people in the labor force.

    According to the BLS, The labor force is the sum of employed and unemployed people ages 16 and older at a given period.

    Their recent report about July’s unemployment rate was contrary to what many people would have expected. People were expecting a somewhat slowdown in the job market, but clearly, this hasn’t happened yet. The Fed has been raising interest rates to control inflation. The Fed’s policy aims to cool the overheated economy by reducing overall spending by individuals and businesses.

    So what does a low unemployment rate mean for you?

    If you are looking for work or want a change of job, right now could still be a good time for that. There’s a huge likelihood of you finding it sooner than later and as per your terms. With many employers paying higher salaries, it is a good time to ask for a raise if you think you deserve it.

    When the effects of tightening monetary policy start showing up and we see a reduction in jobs created, it might be a little late to negotiate.

    As always, if you enjoyed reading my post and learned something, please feel free to write your views in the comment section below. Thank you, till we meet again next time!

  • How to always make money in the stock market? What is a Dollar Cost Averaging?

    Today, I will introduce you to a very useful concept called Dollar-cost averaging. It is an investment strategy where you invest a fixed amount of money every period, such as every month, despite the stock market trend. You could invest your money in an index or mutual fund, or electronically traded funds (ETF).

    So, no matter how the stock market behaves if you keep putting in a fixed dollar amount every period, over the long run, it will surely give you good returns.

    Let’s understand this with a help of an example. The dollar amount you contribute each period, divided by the stock price, gives you the number of stocks you buy for that period. So, when you invest a fixed dollar amount (let’s assume you contribute every month), you end up buying fewer stocks when the stock price is high.

    Conversely, when the stock price falls, you buy more stocks for the same dollar amount you invested during that month. This way, your average purchase price per stock stays low over time.

    There is an excellent example explaining dollar cost averaging that I found on the Charles Schwab website.

    To be a successful investor, you need to have patience and invest for the long term. People expect their money to grow overnight and this certainly doesn’t happen.

    Why people need to use this strategy?

    People try to buy stocks when their prices are falling and sell when they are rising to make profits. But it is very difficult to time the market. There is no foolproof way to know how the stock price will behave the very next day or coming days.

    Sometimes, you may buy a stock thinking it is selling at a low price and will rise in the future. If the stock price rises and continues to rise, you made a good investment decision until you sell it at a higher price and make a profit. However, if the stock price falls further for the next few days, and you end up selling it at a lower price than you bought it for, you made a mistake.

    Dollar-Cost Averaging

    In reality, people panic and start selling individual stocks when the stock prices are going down. This is actually the wrong thing to do.

    Also, people, sometimes, don’t buy those underpriced stocks thinking they are not performing well and will continue to fall.

    We, as individual investors don’t have enough information about a specific company and other economic events. Hence, our guesses about market stock price and index movements are not always correct.

    How does Dollar cost averaging help?

    This can be avoided when we invest a fixed dollar amount. With dollar cost averaging, you can stick with a good investment schedule and will not overthink about when to buy or sell stocks.

    I like to invest worry free

    Thus, a big advantage of dollar-cost averaging is that it is a worry-free method of investing. The emotions and anxiety associated with investing are taken out and you just invest a fixed amount at a fixed time (such as every month), ignoring the market ups or downs.

    An example of dollar-cost averaging investing would be the investments done through your employer’s 401k plan. Here you and your employer contribute a fixed amount of money towards your retirement income.

    I hope you learned something from my post today. If you haven’t already, you will start making use of this useful technique in making your investment decisions. Also, please start early, as time is the key. After creating the emergency fund in your savings account, invest your money so it can grow.

  • Saving vs Investing

    What is saving?

    Saving is the extra money we are left with after meeting our expenses from our income. It is the difference between our total income and our total expenditures.

    There are several things we can do with that extra money. We can either leave it at home (the worst option) or keep our extra money in a bank, such as in a savings account or invest it.

    In this post, I will cover how much money we should save in a bank vs investing it to grow it.

    Advantages of having a savings account in a bank

    First, and foremost, we need to understand money loses its value over time because of inflation. So, even though the interest paid on a savings account is not very high, we still get some interest to compensate for loss happening from inflation. Thus, it is certainly better than keeping it in your house, as you don’t earn any interest when you keep it at your house and will lose its value due to inflation.

    However, the best part about a savings account is that your money is safe in a bank, as most commercial banks in the US are insured by FDIC. FDIC is Federal Deposit Insurance Corporation that insures that will not lose their money if that bank goes bankrupt.

    In other words, people who deposit money in a savings account protected by FDIC for up to $250,000.

    So, when looking for a savings account, make sure your bank has FDIC insurance. Also, if you want to select a bank for a savings account, you should look for one that charges the minimum fee for you to hold an account.

    Another important use of keeping money in a savings account is that you can withdraw it for expenses such as a down payment for a car or a house.

    Get that Emergency fund established first

    People also keep money in their savings accounts for emergencies. I strongly feel everyone should create an emergency fund. If something were to happen to our income, we should have at least 6 months’ worth of money to survive.

    So, keeping money in a savings bank doesn’t make you rich, but it helps in creating an emergency fund and meeting some big expenditures. So before, we start investing, we should have at least 6 months’ worth of money in a savings account for emergencies.

    This can change based on the size of the family and sometimes people need up to 12 months’ worth of expenses if the family size is big.

    Anything after that, we should invest if we want our money to grow.

    What do we mean by investing?

    In finance, investing means when you invest your extra money with the hopes to grow it. The most common forms of investment are stocks, bonds, an index or a mutual fund, commodities like gold and silver, and real estate (property).

    If you are interested in learning more about these options, you can check out my post here.

  • IMF predicts further slowdown for the world economies

    The International Monetary Fund in its latest World Economic Outlook report, published on July 26, 2022, has lowered its estimate of Economic growth for the world economies. This is a downward revision from their April 2022 projections of GDP growth rate for both 2022 and 2023. Below is the chart I took from the IMF website showing their growth projections by region.

    I have tried to summarize the main points of the report for you. If you are interested in reading the full report, please click here. https://www.imf.org/en/Publications/WEO/Issues/2022/07/26/world-economic-outlook-update-july-2022

    Lower GDP growth but higher inflation globally in 2022-23

    The GDP of the World is now expected to grow at 3.2% this year and 2.9% next year, compared to what they had predicted in April to be 3.6% in both 2022 and 2023.  While they predicted lower GDP growth across the globe, they raised their inflation estimates. The report predicts a 6.6% inflation in advanced economies and 9.5% in emerging and developing economies.

    What are the main factors behind this?

    The report cited various reasons for its downgrade revision. On top of the pandemic after effects, higher-than-expected inflation has been a major cause of worry worldwide, especially in the US and major European countries. This has caused the central banks of these countries to raise interest rates, making financial conditions tighter.

    Additionally, China’s economic slowdown has been worse-than-expected due to its zero covid policy. This has caused longer lockdowns, affecting their exports to the major US and European economies, and causing supply chain issues. This has also led to a supply-induced inflation.

    The report fears that given the current scenario, the Russian – Ukraine war could continue for long and sanctions associated with it could go up further. This will, unfortunately, cause more problems in energy and food markets’ supply.

    They also ran an alternative scenario of a possibility of a full shutdown of Russian gas flows to Europe by the end of 2022. If that happens, GDP global growth might fall further to 2% next year. The report also stated that since 1970, global growth has only been lower five times, so this does look very gloomy.

    What should the countries do to overcome this?


    The report suggests that controlling elevated inflation should remain the priority of policymakers around the world. This requires tightening monetary policy, and many central banks have started to do that already, both in advanced economies and emerging markets.

    They also noted the role of Fiscal policy is important here to protect the vulnerable population. But it is important that the fiscal policy (like in the form of subsidy or stimulus payments) should only target the weaker population and should not interfere with the overall disinflationary motive of monetary policy. Because a lot of inflation in the advanced economies was caused by this issue, where too much money was chasing too few goods. In other words, people got the money to spend, but not that many goods and services were getting made, causing excess demand and inflation.

    The report concluded that policymakers must continue to work on increasing vaccination rates to protect against future outbreaks. Lastly, countries must collaborate to address climate change and speed up the green transition to avoid their dependence on oil.

    Please let me know in the comment section your feedback on what topics you would like me to write about.

  • Why did Fed raise interest rates again, making borrowing more expensive?

    Ending their two-day meeting, the Fed (central bank of the US) has once again raised interest rates. The reason for the hike is to control inflation. The United States Congress has given the Fed a dual responsibility – to achieve maximum employment and keep inflation around the rate of 2% over the longer run.

    The average consumer in the US has been feeling the burden of rising prices, especially since the start of this year, esp. in gas, housing (including rental), and food prices. The Consumer Price Index, which measures inflation in the US has been at an elevated level for quite some time. In their press release, as of July 13, 2022, the BLS published inflation at 9.1%.

    How does the interest rate affect inflation?

    Going back to today’s news, let’s understand how the interest rate mechanism works. The FOMC (Federal open markets committee) is responsible for determining the federal funds rate target range. This is the rate at which banks borrow from each other. The Fed doesn’t set this rate, but market forces determine it.

    The reason this rate is very important to us is through its linkages to other rates. This federal funds rate impacts all the other interest rates such as on credit cards, housing, auto, and education loans.

    How much did Fed raise interest rates?

    In today’s meeting, the Federal open market committee decided to raise the target range for the federal funds rate from 2.25% to 2.5%. This increase has moved the Federal funds rate to its highest level since December 2018. During their June 13, 2022 meeting, they increased the target range for the Federal funds rate to be 1.25% – 1.75%. You can see the graph of this rate over time here.

    So how does the Fed steer the federal funds rate?

    It uses “interest on reserves balance” as its main monetary policy tool for that. To understand it better, you can read my article here, which explains this in detail. When the Federal funds rate (borrowing costs of banks) is high, banks will pass on these added costs to their final consumers. These consumers include people like you and me, and businesses.

    In a nutshell

    The main idea behind this repeated increase in the interest rate is that expensive loans will discourage people from spending. When the cost of borrowing (interest rate) is high, general consumers (households) borrow less for a big purchase such as a car or a house. Similarly, businesses also invest less in the expansion of their plant, inventories, machinery, buildings, etc. All of this will reduce the demand for goods and services these businesses make and they will also hire fewer workers. And when the excess (increased) demand is lower, the prices will eventually start falling, which will control high inflation. Thus, interest rate hikes are the Fed’s main tool to control inflation.

    Inflation happens because of strong consumer demand, which supply can’t match. Supply bottlenecks with China during the Covid pandemic, Ukraine war, etc have all contributed to a weaker supply of many essential items we use every day. Since many of the supply chain issues will take a long time to fix, the Fed is trying to control the demand aspect of inflation. By raising interest rates, and making borrowing more expensive, the Fed is hoping to weaken Americans’ willingness to spend money and ultimately bring inflation close to its 2% target level.

  • Commonly used macroeconomic terms that you should know

    Today, I explain some of the most widely used macroeconomic terms relating to a country’s economic performance. These are the terms we often read in the news, so we need to understand what they are and how they affect us. My list is not comprehensive, but I feel it is a good start. In my future posts on Economic Glossary, I will be explaining the meaning of some other important economic terms, so please stay tuned for that. For now, let me explain the ones that are coming to my mind as I type.

    Interest rate: It is the cost of borrowing money or the return we get from saving our money. By changing interest rates, the Fed (central bank) can influence economic growth. Low-interest rates encourage spending and investments and make the economy grow. On the other hand, rising interest makes loans more expensive and lowers investment. This reduces firms’ hiring, employment, and thus total demand in the economy and can lower both inflation and GDP growth.

    GDP: It measures the size of the economy. It is the market value of everything (final goods and services) produced in a country, whether it is made by its citizens and companies or by the rest of the world. Market value is how much we pay for something, such as the market price for that bread we eat or the plumbing service we get. The US GDP number is published every quarter to see its trend. Economists at the U.S. Bureau of Economic Analysis estimate GDP by using a lot of data gathered by other federal agencies and private data collectors. As of Q1, 2022, the US Real GDP was $19.7 trillion. The US is the number one economy in the world when measured by real GDP.

    GDP Per capita is the GDP divided by the total population. It shows the standard of living of its people and this number is published once a year. Real GDP is the GDP at constant price or base year prices. This measure removes the effect of rising prices on GDP. GDP growth rate is a % measure that calculates real GDP growth as compared to the previous quarter or the previous year. This could be a positive or negative % depending on an increase or decrease in real GDP. To know more about US GDP growth, click here.

    Recession: A recession is a significant fall in the economic activity of an economy. It is mostly seen as a decrease in income and employment. During a recession, there is a significant drop in consumer spending. Some businesses can go bankrupt, people out of school don’t find good jobs and people might lose their homes when housing prices fall. If you want the exact definition of recession or expansion in the US, here’s a good source https://www.nber.org/business-cycle-dating-procedure-frequently-asked-questions

    Inflation: The inflation rate is a sustained rise in the average price level during a specified period, usually a month or a year. It is calculated as a % increase or decrease in prices from the previous period. Inflation exists when prices increase but our purchasing power reduces over some time. As seen in my post here, demand, supply, and future expectations about inflation affect inflation. 

    US Government and the Fed both measure and publish inflation numbers every month. They use CPI and PCE respectively for measuring inflation. Sometimes, the CPI can give us misleading information because it includes food and oil/gas prices. These numbers are usually more volatile. The core inflation rate excludes food and energy prices and thus is a better measure of the inflation rate. The Personal Consumption Expenditures price index is another measure of inflation. It includes more business goods and services than the CPI. For example, health care services paid for by health insurance companies are part of PCE and not CPI.

    Unemployment rate. Every country sets a target unemployment rate that it seeks to achieve. In most advanced economies it is a lower % compared to developing economies. In the US, The BLS publishes this % every month. The Fed aims to keep the unemployment rate around 4%. The unemployment rate represents the number of unemployed people as a percentage of the labor force. People in the labor force include people 16 years of age and older, who are either employed (have a job) or unemployed (those who have looked for a job in the past 4 weeks but couldn’t get one).

    As of June 2022, the unemployment rate in the US was 3.6%. The total number of unemployed persons was 5.9 million.

    Monetary policy or the Fed: Federal Reserve is the central bank of the U.S. The Fed performs many important functions such as supervising the nation’s commercial banks, conducting monetary policy and providing financial services to the U.S. government. It also promotes the financial system’s stability by taking measures to prevent crises like recession and bank failures.

    The Fed is not just one bank but consists of 3 main components.

    1. Seven Board of governors guide the entire monetary policy and set the discount rates for member banks
    2. 12 regional federal reserve banks are located in Atlanta, Boston, Chicago, Cleveland, Dallas, Kansas City, Minneapolis, New York, Philadelphia, Richmond, St, Louis, and San Francisco.
    3. FOMC, the Federal open market committee. It meets eight times a year and makes decisions that help promote the health of the U.S. economy and the stability of the U.S. financial system.   

    The Fed is an independent entity and is not affected by U.S. politics. Congress has given Fed a dual mandate of stable inflation and maximum employment. The Fed tries to keep prices stable with a long-term 2% inflation target and also promotes maximum employment. Please see my detailed post on how Fed in the US uses its monetary policy tools to keep inflation in the target range.

    Fiscal policy : Fiscal policy is the term used to describe the spending and taxation decisions of a government that can influence an economy. For example, the government can lower taxes and raise spending to boost the economy when needed. Governments often spend on infrastructure projects to create jobs and grow income to take the economy out of a recession.

    Similarly, the Fed increases business investment and spending by lowering interest rates. In a boom situation, when the economy is overheating with high inflation and very low unemployment, they do the opposite. The government reduces its spending and raises taxes. Alternatively or in addition, the Fed raises the federal funds rate which in turn increases all the other interest rates in an economy and thereby puts a break on overall economic activity. Thus, either fiscal or monetary policy or both can be used to expand or contract the economy.

  • What does a vaccine, a park and a factory have in common?

    These are all examples of externalities. Sorry, if this sounds too complicated at the beginning, it will all make sense as you read along. Externalities can happen when the after-effects of certain actions can spill over to other people not directly involved in it. These could be either positive or negative spillovers.

    Externalities can arise between producers, between consumers or between consumers and producers. Externalities can be negative when the action of one party imposes costs on another, or positive when the action of one party benefits another.

    Let’s look at an example of a positive externality. Vaccination for any infectious disease would be a positive externality because vaccination will reduce the overall severity, symptoms, and thus the possibility of spread of infection of that particular disease. This will also benefit people who are not vaccinated through positive spill overs by others who are. People who didn’t receive the vaccine are less likely to get an infection if more and more people around them are vaccinated. Vaccination also reduces the burden on a country’s healthcare and benefits society. Most recent example of this is the Covid 19 vaccine, which was provided mainly by the government in many countries to stop the spread of infection.

    In both positive or negative externalities, government intervention is required to make sure the businesses that create externalities get the benefits for positive externalities or pay the price for negative externalities.

    If a factory is producing toys but at the same time polluting the environment, people are bearing the cost of pollution. This is a negative externality. From an economic perspective, the business is transferring some of its cost of production to society. Without any tax on pollution, that business factory’s actual cost of production is less than what it should be, so it can charge lower prices from the people for the toys it produces. This reduced price creates more demand for toys, making the business produce more and more toys and thus polluting the air more.

    In our first example above, the factory will find ways to reduce its chimney smoke from polluting air if it has to pay the price for its pollution. Government can impose taxes in these cases. Tax will also increase the overall cost of production for the business. The business will be forced to charge higher prices from the consumers, which will, in turn, reduce the demand for it and the over-pollution problem will be solved to some extent. Similarly, water pollution that is caused by industrial effluents can harm ocean life, other plants, animals, and humans. The government imposing a tax on factories creating water pollution can limit it to some extent. In economics, the use of tax to limit negative spillovers is known as internalizing the externality.

    Another type of negative externality is caused by smoking. The government wants to discourage smoking and thus impose heavy duties and taxes on cigarette manufacturers because active or passive smoking both are harmful to society. Thus, cigarettes sell at a fairly expensive price. People who can’t afford to buy can refrain from consuming it. Also, smoking is banned in public places and to minors, these are all attempts to reduce the consumption of smoke.

    Similarly, to encourage businesses with positive externalities, government can provide subsidies to those producers. When producers get subsidy it lowers their cost of production and it encourages them to produce more. Also, the subsidy is a government expenditure, which government meets through taxation on general public. This taxation on general public is either form of direct tax (like income tax) or indirect taxes (like those paid on goods and services when we buy them.) Thus, the society who is reaping the fruits of a positive externalities ultimately ends up paying the price of subsidy.

    One example of this is public (government funded) education, when the government subsidizes public education, a greater quantity of education (more schools and colleges) is made and the society as a whole reaps the spillover benefits of more educated people. Also, parks, the police force, and public hospitals provided by the government provide benefits to any person who lives in the neighborhood. These are called public goods with positive externalities that are nonexcludable and benefit the larger public who indirectly pay for them through taxation.

  • If money doesn’t grow on trees, how and where does it grow?

    How do we grow our money? We all know that unfortunately, we can’t grow our money on trees. But there’s a way to have more money in the future. If we start saving early and make regular contributions to it each month in an interest-bearing account with a bank, our money will grow. I will prove how an economist would do it- you guessed it right, by using graphs and numbers!

    For the younger generation, this post might be particularly useful. As soon as you start getting paid from your first-time job, whether it is a part-time job, or your first full-time job after college, you must learn to save for your future. American economy and many other economies nowadays are very consumption-based economies. People tend to live above their means and take loans to buy luxury things early on in their lives instead of saving money for the future. Our current generation needs to understand that there is no shortcut way to getting rich. Saving a portion of your income every month is key to having a secure financial future.

    A very important factor for anyone’s wealth creation is to learn to start budgeting. Before you spend money on any of your expenditures, you must set aside some money to pay yourself first. By paying yourself, I mean depositing a fraction of your income in a bank account that pays you some interest.

    Banks are considered low-risk and safe places to save your money. In the US, deposits at banks are insured by the Federal Deposit Insurance Corporation, FDIC. Deposits held at credit unions is administered through the National Credit Union Administration, NCUA. Your money is very safe in a savings account and is almost risk-free, hence the return paid on savings is not very high. Risk and return move together. It means higher the risk, higher the return, the lower the risk, the lower the return.

    Inflation erodes money’s purchasing power, so keeping extra money sitting idle at your home is not a good option at all. A portion of your money should be either saved in a savings or time deposit account in a bank and some portion should be invested in high-return, high risk assets. In another post, I will go over where you can invest your savings besides keeping them in a bank. For now, our focus here is to understand how money grows with compound interest over time.

    Just with the power of compounding, you can grow your money by a lot and a few years by just keeping it in a time deposit in a bank. Compound interest, or compounding, means that interest is earned on both the amount you initially deposit, which is called Principal, as well as on the interest you earn each day until you withdraw your deposits.

    The rate of interest that the bank pays us is expressed as a percent. Two main factors will determine how fast money has grown when you withdraw your savings deposit. The first is the time component and the second is the rate of interest.

    Mathematically, we can express this as

    = P (1+i)t/ 100

    Where P is called the Principal amount that we deposit initially in a bank

    i is the nominal interest rate that the bank pays

    t is the time period for how long we’re saving

    I will explain this with a simple example. Let’s assume that I started saving at the age of 17 and initially deposited $1000 in a savings account with a bank at 3% interest rate and kept it for 20 years. Now each month, I started depositing $50 into my account. This means I have deposited $1000 + $12000 during the 20-year period. Are you curious to see what happens to my money in 20 years? With the power of compounding, my money has grown to be at $18,235.85. I magically made an extra $5235, which is $18235.85-$13000.

    If I didn’t make a monthly contribution to my savings of $50, my money would have only grown to $1820.75 in 20 years. Thus, we see that the regular savings contribution is a very important factor in growing your money. Simply putting a certain amount of money into a bank savings account before you pay any bill or buy anything, will help a great deal in growing your money.

    Now, if we assume that this time duration increases from 20 to 50 years with the same monthly contribution of $50 per month and the same initial deposit of $1000 when I retire at the age of 67, I will get $73,939.46. If I add my monthly contribution of $50 each month for these 50 years with the initial deposit of $1000. I would have contributed a total of $30,950 by age 67. This $43,000 got created just with the power of compounding.

    If the interest rate goes up from 3% to 5%, and I keep saving $50 a month with the same initial deposit of $1000, my total money would become $145,551.98 at the end of 50 years. And I will be so happy.

    Now, let’s change one variable of the equation, our time duration t. Let’s assume that instead of starting to save at the age of 17, I started saving at the age of 30. I want to show you the exact figure of how much less money I would be able to collect after 37 years. In this case, the total time is reduced from 50 years to 37 years and even though the rate of interest is higher at 5%. I will only have $70,360.49 instead of $145551.98.

    Thus, by looking at all these examples, we understood that it is just not how much you save but also how early you start that will help your money to grow. The power of compound interest is making your money grow exponentially, doing the job for you. * For our math-savvy readers, did you notice that the time variable t appears as an exponent in the equation above and thus, shows the exponential rather than linear growth.

    You just have to put your saving in a safe interest-bearing account such as CDs or time deposits with a bank and make routine contributions to it, and please start early. Once you have the job, you can get the money directly deposited from your paycheck each month into your account.

    So yes, always remember to pay yourself first.

    As I wrote earlier in my post, there are a few other options available in the market to save and invest your money. Some of these options can give us higher returns than banks do but they also pose higher risks as well. A recent article by Bankrate lists some savings and investment options in the US with no to very low risk. We will go over those in my next post.
