Introduction to Mixed Strategies in Game Theory

Hi Everyone, in this video I introduce mixed strategies in game theory. I do have a video that goes through mixed strategy nash equilibrium in the battle of the sexes game: ruclips.net/video/MIJB6tY8BR8/видео.html It is a good idea to make sure you are confident with the more rudimentary theory before you get onto this stuff. I have some videos that might help with that background: ruclips.net/...

    • @econhelp_official

      Hi! I think I understand your question but I'm not certain. - I think mx+b can work: if we understand b = vertical axis intercept = number of vertical axis good we can make if we allocate all of our resources to the production of that good. Plus, the slope of the ppf is equal to the opportunity cost of making the horizontal axis good. So I think it could work if we can get that information. Does that help?

    • @econhelp_official

      Really good question! So... in more complicated models we actually find that the general equilibrium result in perfect competition is that the ratio of prices is equal to the opportunity cost. But that's like... second year uni usually. At this level, when you are just starting, I wouldn't bring prices into it yet. We have models to find prices and you have to get through those models first... for instance, prices are determined, in perfect competition, at the intersection of demand and supply. Here, we are just getting into the mindset of thinking about what it means when we are trading off between two things.

When we normalise that ratio to be in terms of 1 Radio, we see that Jack gives up 3/2 TV's for 1 Radio.

    Why did You not invert the function?

    • @econhelp_official
      @econhelp_official Месяц назад

      Thanks for the question! So the strategy of setting each variable to 0 and solving for the other in order to find the intercepts will work whatever form the function is in. For instance, note that the inverse demand function: P=25-Q/2 describes exactly the same relationship as the demand function: Q=50-2P It just looks different. You can check by setting each variable in each function equal to 0, both functions solve for a quantity axis intercept of 50 and and price axis intercept of 25. We can actually represent this relationship in a number of ways: Q-50+2P=0, P-25=-Q/2, ... etc. These are all legitimate algebraic descriptions of exactly the same relationship and the same curve. The first form (where P is on the LHS) is called the "slope -intercept" form of the equation of the line because the constant o the RHS is equal to the P-axis intercept and the coefficient on the quantity variable equal to the slope. So it's special in that way, but really you can use any form of the equation you want. Does that help?

    I'm an ACCA student, and in F5: performance management we have to study this topic, I can't begin to explain what they've done to it in their syllabus, they outright refuse to use the brain... at all, and I'm not saying this out of anger or disappointment, it's just the way things are. E.g they refused to teach us Marginal Revenue bcz, and I quote "Studying MR requires mathematical derivatives, many of the students haven't studied it so it's not part of your ACCA syllabus, we'll just give you a formula MR=a-2bq, and elasticity is constant, wtf are derivatives? and oh, this "model" cannot be used in the practical world bcz it uses the high-low method, it assumes a linear relation btw demand and price" Then how about you don't use the high-low method? HL method is the biggest nonsense ever, stop shoving it down our throats. ever heard of regression? there are so many types of it, one of them might be appropriate? or how about you use some statistics and probability if appropriate? how about you don't assume a linear relationship btw Q and P? How about you stop doing the stupid things you're doing? Maybe the model would work if you would at least try to use your brain. WTF man???? I studied calc 1 in high school when I was 17, I studied multivariate calc and (some) differential equations on my own, calculus is the easiest thing out there and they refuse to do anything that requires them to use their brain, they do this all the time, they do this to everything, consider the problem of limiting factors, now imagine the most stupid way of approaching this problem, well ACCA have you covered, they teach Marginal and Throughput accounting, that only deals with one limiting factor, if there are two products and many limiting factors, there's linear programming, well, what if there are many products and many limiting factors? you may ask: "Well then go duck yourself, we can't teach you anything that's of value and requires you to use your brain". And I can't even begin to tell you what they taught us in the learning curve, this is the most stupid subject ever. Studying it just boils my blood. If someone is reading this, just don't go into accounting, and don't do certifications, they're not a good education. Go to a proper university and study a stem degree.

    Thank you for the video! so why is mr steeper than ar?

    • @econhelp_official
      @econhelp_official 2 месяца назад

      I'm not sure how to think about this is terms of slope. Here's an initial thought: what we want to explain is that the MR is not only less than AR, but increasingly so. This will give us the steeper slope. From this perspective, the answer may well be "because the price decreases": - as we increase quantity, the additional revenue we get from that additional quantity, gets smaller and smaller because the price we get for that additional unit gets smaller and smaller. Thus we get MR steeper (below our demand and increasinly the gap gets wider). Does that help? Another way to think about it is with elasticities and connecting it with the TR curve, but I'm not sure if that helps.

    • @econhelp_official
      @econhelp_official 2 месяца назад

      Yeah it's a good question, I hadn't thought about it in terms of the slope. I think it's really good to see this through the elasticities as well, that gets to the issue in another way. In the top half of the curve we go from perfectly elastic to unit elastic. This means that increasingly, as we decrease the price, the demand gets less responsive to changes in price (quantity does not change so dramatically given a decrease in the price). I'm pretty sure I go through that here: ruclips.net/video/uawjookzs4Y/видео.html... So then we link it all to the hump shaped TR curve. Another way to think about it is that MR can't ever be flatter than AR (otherwise at some point MR will become greater than AR, which we know from this video can't be true). So then the question is, why isn't it just the same slope? Well... the price is decreasing. each time we increase q, that part of MR that increases (because we sell one more unit) is getting smaller and smaller (since price decreases) so MR gets smaller more quickly (i.e. it is steep). ... I hope that makes sense, it's actually hard to articulate! :)
