Paige DeWitt-Holub 3/07 Price in session 1 (average prices), Quantity in same round (draw lines) Quantity was 14 in session 1 The theory behind this states that the quantity would go down as a hypothesis -the price will go down by each price tax addition, but not by a correlative amount of the price -the buyers should pay more by each, not by tax amount/sellers receive more, again not correlative when you “average” sessions 1 and 2, the prices should idealistically be the same -always same amount of buyers and sellers with alternating terms graph, explain, make theories/predictions 3/09 “Lecture #9 I. Producer Theory A. Cost of production I. Accounting costs vs. economic costs B. Long- run vs. short run C. Cost curves.” 1 -trying to predict behavior with regards to behavior, not business advice -to think of behavior, like a physical good, would require to think about all of the money it amounts to in order to make something like a meal (ingredients, utilities, labor services) -time is a factor of labor services categories: Total Cost = Fixed Cost (rent, doesn’t increase with more of the amount of renting/production) and Variable Cost Variable cost can be zero but is usually the amount of what was paid out to renters, workers, etc. -if quantity equals zero than it will also equal zero -you can leave fixed costs eventually (ex. Leases end) In the Long-run… the fixed costs are zero. -something can be “constrained”, such as the importance of a company like Google vs a small food shop that can quit more easily in typically a shorter amount of time 1 All quotations are taken from the board of Professor Duncan “Accounting costs – explicit cost Economic costs – include opportunity costs (indirect costs)” -someone who loses money in a business and does not factor in interest includes that they might have an accountant’s version of loss -opportunity costs = the next best opportunity -zero economic profit is okay, if I do the next best thing then I can earn the same amount of profit, positive is better than the next best thing -negative profit means you could have been more efficient – if you calculate what you could have done better, not necessarily negative but in theory “TC = FC + VC” graph this for the best results to find what the cost would be -if it starts at zero, it is a long-run time frame – if it starts at a higher point, of a fixed cost, there will be an amount demanded eventually by the ending of the costs -marginal cost = how much it cost to make that unit, marginal could go up average could go down -to get the average total cost, you divide something by twenty -if you ask something like was the 8 unit profitable, then you will have to figure out the marginal cost and see if it was higher than the money you made – then this would be called marginal revenue -marginal cost = change in total cost divided by change in quantity -Average cost will go down because you are losing fixed investments, marginal costs – actual price of the water company -tangent line cost is the lowest point possible to calculate for each quantity -average is price divided by quantity again -increasing marginal cost vs. decreasing marginal costs and decreasing marginal costs -A realistic cost curve would include a realistic determination of all of the above three graphs: size can become too inefficient -if you want to find total cost, you can look at this graph, but additionally, you can look at average cost/curves to make “Average Total Cost = TC/q Average Total Cost Average Fixed Cost = FC/q Average Fixed Cost Average Variable Cost = VC/q Average Variable Cost Marginal Cost = change in total cost/change in total quantity”
