    For the determinants of supply, wouldn't a producer expectation of a high price actually lower supply today since they would want to sell at a future date when prices are high?

    • @ReviewEcon
      @ReviewEcon  3 года назад +2

      I see your point. I'd say it depends on how the exam question is phrased. If they expect a high price, production will increase to capitalize on that high price. That higher production will increase supply.
      But... If they expect current production can be sold at a higher price later, already produced products would be held from the market as suppliers wait for that higher price. And that would reduce supply.

    Great 👍, sir if price does not change demand .if the price high or low ,will it not effect the demand,get you please explain briefly

    • @ReviewEcon
      @ReviewEcon  3 года назад

      Demand is the entire curve with all prices and all quanties consumers will buy at every possible price. Since price is already part of demand, a change in price won't change it.
      Price does change QUANTITY demanded. At high prices there is a lower quantity demanded and at low prices, there is a high quantity demanded.
      Things besides price, like consumer tastes, that impact purchasing will change demand (shift the curve).
      I hope that helps!

    I think income effects is about when an employ wage higher buy more because the person has morer money now. U talked about price effect in income effect

    • @ReviewEcon
      @ReviewEcon  7 месяцев назад

      As it applies to the AP micro exam, the income effect is as I described it. When your income doesn't change, price increases will decrease the purchasing power of your income, resulting in a lower quantity demanded. Also, when your income doesn't change, price decreases will increase the purchasing power of your income, resulting in a higher quantity demanded.
      The income effect, substitution effect, and diminishing marginal utility all reasons for price inversely changing quantity demanded.
      I hope that helps!

    • @ReviewEcon
      @ReviewEcon  7 месяцев назад

      It appears you are describing a change in worker income as a demand shifter.
      The income effect is about movement up or down the demand curve (that results from price changes impacting the purchasing power of your income) rather than a shift of the demand curve.

    How can price not change demand when a products demand goes up when the price of it's substitute goes up?

    • @ReviewEcon
      @ReviewEcon  3 года назад +1

      When we say price doesn't change demand, we mean the price of the good in question doesn't change the demand for the good in question (only quantity demanded). If the price of another good (a substitute or complement) changes, the price of the good in question did not change (but demand will change). Prices of other goods is a demand shifter.

    The demand for tickets to ethiopian film is given by D(P)=200,000-10,000p, where p is the price of tickets . if the price of tickets is 12 birr, calculate price elasticity of demand for tickets and draw the demand curve. please help me

    • @ReviewEcon
      @ReviewEcon  3 года назад

      While this is a little outside what I teach, I would suggest you plug in the numbers to figure this out. Start by replacing P with the price of 12 to get the Qd (D in the formula) then reduce the price to 10, 8, 6, etc. Also raise the price to 14, 16, 18, etc
      Use the numbers you get (P and Qd) to draw the graph and calculate elasticity.

    • @ReviewEcon
      @ReviewEcon  2 года назад

      Doesn't look like it to me.
      With substitutes there is a direct relationship between the price of one good and the demand for the other good. When the price of one increases people buy less of that good and they buy more of the other good instead. That's why there is a direct relationship.
      For compliments it's the opposite the price of one good is inversely related to the demand for the other good when the price of one increases people by less of that good and less of the complement as well.
      I hope that helps! Good luck on your exams!
