    I think the easiest way of learning this would be that Demand is from the POV of the CONSUMERS whereas Supply is from the POV of the PRODUCERS. Producers are profit-oriented and therefore would wanna increase their prices with the increase in demand.

      doubt
      so when price rise, the supply rise
      so in demand, when price rise, the demand falls.
      so...demand fall.. means some people cant buy goods. the producers will lose after get lots of supplier but lots of sells by price rise

    The law of demand basically says that when the price of something goes up, people usually buy less of it. And when the price goes down, people tend to buy more of it. It's a simple rule that shows how price affects how much people want to buy something.

    The supply curve is a graph of marginal cost, the minimum price for a supplier is the one where the company works as efficiently as possible.
    The supply curve can actually have inflection points because of economies of scale.
    For example the marginal cost to produce 1000 grapes is less than the marginal cost of producing 1 grape. That's because fixed costs like land and tractors can be spread over more units.
    Note the equalibrium price is still always where the supply and demand curves cross.

    @TheGyij2 actually, there is no minimum price, because price will be determined by the supply and demand, and both will also be determined by the price that will act as an incentive to produce or not a certain good.

      When that happens there is an Excess Supply. Therefore the government intervenes in different ways to bring the production down.
      For example things like Market Ceiling
      So before all of this, you should learn about Market Equilibrium. It is the point where buyers and sellers agree to buy and sell goods at a certain price.

    why did the quantity supply increase by price, if the price was increasing which mean that the quantity demanded would be decreased, why would they need to increase the quantity supply if there are now fewer people wanted to buy them?

    • @theouterinn
      @theouterinn 6 лет назад +5

      As someone who isn't too experienced with economics, please correct me if I'm wrong. I believe the prices in these scenarios are after demand is taken into account; no matter how much they are being sold for, it will always cost the same amount to PRODUCE the grapes, the price is just dependant on the market. Therefore, if you are making more money for your grapes, it will give you more reason to produce more, since you'll have the money to do that.
      Hope this makes sense, cheers.

    Quick question. So when he sets a price for each quantity, what determines that price? What factors go into determining that price? Another instance is the price for barrels of oil. How do prices change for a good when the supplier isn't the one changing the price and only the amount quantity sold?

      I am also semi confused. It doesn't quite make sense to me that if the price goes up, you would increase quantity supplied, because if the price were to go up, wouldn't fewer people demand that much of the product? Therefore, wouldn't you be left with a surplus of the product if you increase the quantity supplied when no one is willing to buy more of that now expensive product??

    @TheGyij2 according to Adam Smith, price will be the sum of wages, profits and wages. and the minimal values to these will be the minimum quantity necessary for the subsistance of the worker, the capitalist, and the landowner. but he's somewhat wrong in this point, because he doesn't distinguish profit from interest, as Eugen Ritter von Böhm-Bawerk did later.
