    My notes on this lecture for you guys, enjoy.
    - What is Microeconomics?
    - Scarcity is what drives microeconomics
    - Constraint optimization exercises where economic agents (firms or individuals) try to make themselves as well off as possible given their constraints.
    - It's about trade-offs. How do you make trade-off things to make you as well off as possible.
    - Opportunity costs is an important concept in microeconomics
    - Every action or inaction has a cost in that you could've been doing something else instead.
    - If you buy a shirt, you could've bought pants
    - If you stayed at home and watched TV, you could've been out working.
    - Everything you do has a next best alternative you could have done instead.
    - They get referred to as the dismal science
    - because their whole point is that nothing is free. There's always a trade-off, there's always an opportunity cost.
    - your constraint optimization means you're going to have to pass up one thing to do another.
    - because of Microeconomics, you can understand the decisions that drive our economy.
    - Supply and Demand model
    - Models aren't 100% true, but always pretty true, "pretty" being between 10% and 95% true.
    - The idea is to make a trade-off. We want to write down in our models a set of simplifying assumptions that'll allow us, with a small set of steps, to capture relatively broad phenomena.
    - To capture those broad phenomena, you want to do it in the most tractable possible way.
    - Positive analysis
    - is the study of the way things are
    - Normative analysis
    - is the study of the way things should be
    - Example of eBay auctions
    - Auctions are a terrific example, they're like the textbook example of a competitive market. Demand comes as a bunch of people going on and bidding. People who want it more, bid more. So you get a demand curve. The higher the price, the fewer people you're getting to bid. Supply is how many units of it are for sale on eBay. You bid until those two meets. And then you have a market equilibrium at that bidding price.
    - Example: someone offered their kidney for auction. The bidding went nuts. It started at $25,000. It climbed to $5m before the auction was shut down, and eBay wouldn't allow you to sell your bodily parts on eBay.
    - This raises two questions:
    - The Positive analysis question: Why did the price go so high?
    - Because the demand is high (because I'd die without it). Supply is low because not a lot of us are willing to sell their kidneys to eBay. Low supply, high demand led to a higher price.
    - The Normative analysis question: Should you be allowed to sell your kidneys on eBay?
    - The standard economics answer to start would be, of course, you should. We're in a world of thousands of people die every year because there's a waiting list for a kidney transplant. And these are people who would happily pay a lot of money to stay alive. Meanwhile, there are hundreds of millions of people walking around with two kidneys who only need one. And many of these people are poor. And lives could be changed by being paid $1m. So this is a transaction that makes both parties better off. So the standard answer would be that you should be able to sell your kidneys on eBay. The question is, why would we want to stop this transaction?
    - The first type of problem comes out of the category we call: Market failures. And MF are reasons why the market doesn't work in the wonderful way economists like to think it should. For this example, there could be the problem of fraud. People might not be able to tell if they're getting a legit kidney or not.
    - There could be an example of imperfect information. Do you know what the odds are that you can spend the rest of your life with only one kidney? We ought to know that before we start selling our kidneys.
    - A second problem is what we call equity or fairness, which is we would end up with a world where only rich people get kidneys.
    - The third problem has to do with behavioral economics., which is essentially, that people don't always make decisions in the perfectly rational, logical way we'll model them. People make mistakes.
    - You do the positive analysis to understand the economic framework before you start jumping to drawing conclusions. We have to be disciplined. We have to start with the fundamental economic framework.
    - Economics at its core is all about how the market knows best, and that basically governments only mess things up.
    - How freely should a market, should an economy function?
    - We have a capitalistic economy. And in a capitalistic economy, firms and individuals decide what to produce and consume, may be subject to some rules of the road set by the government. There are some minimum rules of the road to try to avoid fraud or misinformation, but otherwise, we let the dice roll.
    - The other extreme is a command economy. In this case, the government makes all the production and consumption decisions. The government doesn't just set the rules of the road, the government owns the road. The government says we're going to produce this many cars this year. And people can get them in some way. It could be a lottery, could be waiting in line. We'll allocate how many get produced and who gets them. The government decided how many shirts, cars, TV's, everything decided how much to produce. Problems with this model:
    - Too many opportunities for corruption when the government controls everything.
    - It's hard to control human nature.
    - Adam Smith's invisible hand is that the capitalist economy will manage to distribute things roughly in proportion to what people want. Folks who want a certain kind of car are going to want to get to that kind of car.
    - Adam Smith's view (the invisible hand view) is that consumers and firms serving their own best interest will do what is best for society.
    - The fundamental core of the capitalistic view is that consumers and firms serving their own best interests will do what ends up being best for society.
    - It can lead to outcomes that aren't fair.

    5 Things I learnt:
    - Microeconomics is the study of decision making under scarcity. It is basically a series of constraint optimisation exercises where economic agents (firms or individuals) try to make themselves as well off as possible given their constraints.
    - Opportunity cost: Every action or inaction has a cost that you could’ve been doing something else instead.
    - A model is a description between two or more economic variables. Models are never 100% true, but are generally true, about 90 to 95% of the time. George box said, “All models are false but some models are useful.”
    - Positive analysis is the study of the way things are and normative analysis is the the study of way things should be. We should consider two things to see why something shouldn’t be the way it is: market failures (fraud, imperfect information), equity or fairness and failing to understand that people make mistakes and that their decisions aren’t perfectly rational.
    - Economics at its core is that the market knows what is best and that governments only mess things up.

      It's interesting watching this having studied economics in the Nordics. The heavy leaning on Adam Smith seems a bit apocryphal. Even referencing Smith so heavily the ie. "invisible hand of the market" etc. in opening lectures, while having touched on the problems of why the "invisible hand" really doesn't work (market imperfections etc.).
      It's interesting since he says economics is inherently "right wing", without defining right or left wing politics. Having an open market with basic regulations isn't inherently right or left wing according to my definition. Neither is the basis of economics, assignment of value is as relevant to a command economy as it would be to a "capitalistic" economy. The meaning of capitalism as a term varies by definition as well, but having *capital* doesn't really nullify the possibility of having a command economy. Capital is just a mean of exchange.

    I would highly recommend reading "Basic Economics: Theory and Cases" by Attiyeh, Bach, Lumsden as an introduction. Wonderful "programmed learning" type of text book - you need to focus and keep answering questions (fill in the blanks in the text) as you read the book. Answers are at the bottom of the page. There are review questions with answers at the end of each chapter followed by a case study (no answers). Calculus not required. I learnt basic Economics from this book. It is fantastic.

    As a third year undergrad in Economics at Sorbonne University in Paris, this video was relaxing to watch. Currently on holidays soon to start again I needed a refresher on basic economics. The professor is very concise through the explanations it was a pleasure listening to him. Of course, especially for the classical theory of market, lots of assumptions are to be made including the most notable one being the theory of rationality. It's both a good & bad thing that we aren't always rational ! Economics has not be taught enough has anything but the laws of the universe, people need to understand we humans are supposed to get ahead of Economics, understand how we got here today & why we can chose a better world.🙂

    The thing I would like to clarify with regards to this lecture is that it is absolutely possible to engage with normative questions irrespective of one’s understanding of positive analysis. Ethicists do that all the time and they are the authorities on normative analysis.
    Additionally, Smith’s invisible hand only exists in theory as we have heavy government intervention in practice. There is no evidence to suggest that a free market leads to equitable outcomes which is probably why we have said government intervention.
    I think, for everyone listening to these lectures, it’s important to question the normative assumptions underlying economic theories and models.
    Obviously, I’m sure the lecturer is aware of all this and there is only so much one can cover in a lecture.

    The law of demand and supply, otherwise is a fragile law between natural and artificial phenomena. For example, when an engineer at MIT desgin a device and prove utility, depending on its intensity, it can absolutely change economic environment. This turns attention to new demand and supply sources to a certain extent.

    1.What's microeconomics?
    Micro economics is the study of how individuals and firms make decisions in a world of Scarcity. A series of constrained optimisation exercises Where The individuals and the firms strive to make themselves much well as they can in the presence of constraints.
    It is about trade-offs how to trade of things to make yourself as well possible.
    It is also the idea of the notion of opportunity cost.
    Economics is generally termed as dismal science.
    2.Supply and Demand.
    An economics model is a description between two or more economic variables by simplifying assumptions.

    Consider two firms that produce perfect substitutes with the same marginal cost c = 1 in
    an infinite horizon setting. The market demand is stochastic: At each period t, it can be
    low (qL = 10 − p) with probability 1
    2 , or high (qH = 13 − p) with probability 1
    2 . At each
    period the firms learn the current state of demand before choosing prices simultaneously.
    Future payoffs are discounted at a rate of δ < 1.
    a) Suppose that the firms tacitly collude to maintain the “monopoly position” (charge
    pm
    s ; s = 1, 2, forever)
    a. First calculate the monopoly price for each state of demand.
    Assuming that such a collusion is sustainable, derive the expected value of the dis-
    counted profit of each firm along the equilibrium path.
    b) Suppose that any deviations from the monopoly position will revert the market
    outcome (indefinitely) to a fully-competitive (Bertrand style) one. Compute the
    expected discounted pay-off of the deviating firm under both states of demand.
    c) What is the range of δ over which collusion is sustainable? Is it easier to maintain
    collusion in periods when demand is high or low?

    An important thing to note about his the model he and economists often use for best outcome (he mentions important problems with it that he says he will go into/tweak) is that it is fundamentally utilitarianism (and necessarily a simplified utilitarianism), while the majority of people are fundamentally not utilitarians morally. Nonetheless, educated quantitative utilitarian information (how many ppl benefit and how much) are often still important to making moral decisions even if you are not a utilitarian.

    Both the teacher and the students are enthusiastic unlike most university students in Japan. Rarely do Japanese students raise their hand during a lecture.

      Isn't Jonathan Gruber the architect of the very messed up and failed Obamacare? He was recorded on camera as saying "blame it on the stupidity of the American Voter" when they were in a meeting back when Obama was in office. This guy should be sitting in a prison cell! He was paid $400K of our taxpayer dollars to mess up the healthcare system here in the United States. Do the research! He basically did loads of damage to the United States and got away with it!
