I think I have understood what you’re saying: assuming that one firm could produce more for less, it would have done so already and undercut its competitors; therefore in the long run, the scope for such improvements will be ironed out by competition. There’s a bit of a tension between implications from the margin and a margin. --You can edit this template and create your own diagram. Of course, the two curves are independent. OK, thanks, that helps. This doesn’t make sense. Post Date: April 08, 2020 - Issue Date: April 25, 2020 As for toilet paper, it is not the case that the virus is causing a mass wave of dysentery. In the short-run, though, they don’t have a constant marginal cost, if only because the marginal cost of distribution and management/coordination would rise. Since quantity demanded is now higher than quantity supplied at the ex ante price, producers would fill the gap only if they could increase production at the same marginal cost, that is, only if they could produce additional units at the same cost. If the firm was big enough to affect the market, increasing production could cause the market clearing price to decline enough to eliminate profit. People might find it easier to cut back on whatever they used to use napkins for than cutting back on toilet paper. I have written something similar in response to Dylan (see above). It certainly doesn’t seem like that to me. Meanwhile, what is the local grocer supposed to do? Producing more toilet paper for consumers on its current production lines would require more workers, whose marginal productivity would decrease. An overnight report from a friend in Australia about shortages of toilet paper compels me to write about the supply chain for this product. Draw A Graph Showing Your Analysis And Provide A Written Analysis Along With Your Graph. I get what Jon is saying, that’s because there is opportunity cost for her to make more rings, she has higher inventory costs, and we can’t use the money she spends on supplies for those rings for other things we need like rent and food. The Medium story is very weak on the role of prices and the impact of price controls, but economic theory can fit this gap and help better understand the economic consequences that we observe. The standard supply-demand graph is all you need. Yet, products are highly differentiated, or at least perceived to be highly differentiated. In my career, having done consulting for dozens if not hundreds of companies, the ones that were profitable numbered in the single digits. The answer is found in the basic economic principles of supply and demand. The toilet paper bubble must eventually burst. In economics, “cost” is something that takes place in the future, not the past. We have all kinds of other products like napkins and tissue paper people can divert to use as toilet paper. Even if production lines of commercial toilet paper can be retooled, at a cost, to make a product better adapted to consumer demand, the packaging will also have to be modified. 3) You write that it “depends on the interplay of a lot of factors.” Of course, it does. I also don’t work with companies normally that make a profit. Let me add one point. The C-average child will be happy, but the A-average child will not. Or, will I be able to sell it to Europe at a much lower price? The willingness of consumers to pay for products is known as demand. In a monopolistic market, marginal cost is still increasing, of course (it always does when some factors of production are fixed), but a monopoly does not have a supply curve because its quantity supplied depends on marginal revenue and thus on the demand schedule (curve). Marginal costs may decrease in the short run when you do this or they may increase, it depends on the interplay of a lot of factors. But it doesn’t follow that if she did have the orders, that her marginal cost to produce the 2nd ring would be higher than the first. Here’s what went wrong. This flexibility will probably already contemplate increasing marginal cost if the most likely production is exceeded. Noted your responses and have replied. As production increases further, the MC curve bottoms out and begins to increase even as the AC curve continues to decrease. @Pierre: With all due respect, that’s just not how it works. (Note, however, that a firm can still make a loss, although not maximizing it, on the upward-sloping part of its marginal cost curve–only if, at that point, average cost is higher.). Therefore, it would be irrational to build expensive, greenfield toilet paper factories in response to a temporary increase in demand that must inevitably be followed by a decrease in demand. Working with less equipment, the marginal (supplementary) worker has a lower productivity. Enough people would buy it to ease the demand and insulate us from the hoarders. Supply and Demand, Hoarding, Price Gouging -- and the Coronavirus ... As many of us have experienced in the past few weeks, buying toilet paper, hand … The firm can reduce costs by producing more. Can the machines operate at better efficiency when running 24/7? This may be possible, up to a certain point, for a number of reasons. If your factory can produce 100 widgets, the 101st is going to be super expensive to produce if you have to build a new factory. Price can be greater than MC in a monopoly situation (though output would still be where mc = Mr, and thus the general point that you need an increase in price to induce more production still holds). Hang on, I think I see part of the disagreement here. My guess is those were single rolls of commercial toilet paper. And there are wildly different prices for pieces that are almost identical, certainly are identical from a cost of the inputs perspective. Such probabilistic calculations don’t change the basic model, although they make them more complicated to manipulate if you are analyzing the toilet paper or the Ferrari market. I’m no expert. The supply chain for toilet paper “is not built for dramatic shifts and seasonal demand changes,” said Scott Luton, the CEO and founder of Supply Chain Now, a digital media company. Adding in middlemen doesn’t alter the story much (middlemen exist because of transaction costs. One must always have in mind the standard graph of a competitive and a monopolistic firm. All production planning is based on probabilistic considerations. View desktop site, This graph represents the supply and demand for toilet paper during the Covid Pandemic. Yes, that seems true. P.S. "Paper machines already run 24/7. Since a profit-maximizing firm must always be producing where MC is increasing, then in order to produce more, they need to see higher prices. as it seemingly contradicts the commonplace, stylized fact that there are often increasing returns and economies of scale. The side of safety often has excess capacity such that if one production unit goes down, there is enough available slack to meet production goals anyway without increasing costs. Demand for Marcal toilet paper from retail customers is up over 25%, he said. Maybe I’m messing up marginal cost and average cost, although I think I’ve got those pretty straight. But there IS a capacity somewhere. Dylan: One of the main arguments of John Kenneth Galbraith was that firms create demand. So it does not have a supply curve or, in other terms, its quantity supplied is not given by its marginal cost (which is, of course, increasing, at least in the short-run). The commercial production lines would need to be retooled at the packaging end too, again at additional cost. Why? Right. The Truth About TP Supply and Demand. If your model is as complex as the real world, you have not built a model, but an alternative, side-by-side universe. https://www.wtoc.com/2020/03/25/georgia-pacific-ramps-up-production-amidst-coronavirus-concerns/. This is why one shouldn’t blog before coffee. Creately diagrams can be exported and added to Word, PPT (powerpoint), Excel, Visio or any other document. There’s obviously something fundamental I’m missing here. Therefore, real consumption (C) of toilet paper has not changed. The reason for my optimism: economizing and substitution. That a given price control does create as shortage is a necessary (but not sufficient) condition for the hypothesis that the industry is competitive. The perfectly competitive model works better here. Pierre: “or else you are making a very basic error”. Machines that pulp recyclable paper. Yes, that is what I did mean. You’re not going to want to do that, unless you think you can sell more than just one additional widget. Jon: Instead of “at minimal marginal cost”, you probably want to say “at marginal cost=price”. Phil: Either you (like perhaps Dylan) assume a monopolistic market or else you are making a very basic error: confusing one firm on a competitive market and the market itself. It costs me $20 to make the first one. This is why theory is important: it helps find out which cause has which consequence in what otherwise looks like a big blob. For a monopolist, since they can control the price by restricting output, they face a downward-sloping marginal revenue curve. Thank you for the economic point. When the two toilet paper rolls allowed per customer at the grocery store are not available anymore (the price is low but the thing is unfindable), and when jails fill up with smugglers and black marketers (“hoarders” and “profiteers,” as governments have called them across all modern history), some voices will be raised for toilet paper to allocated, and perhaps even manufactured, by the government. No, there is still increasing marginal cost. Toilet Paper Market $11.00 $10.00 59.00 $8.00 $7.00 $6.00 $5.00 $4.00 $3.00 $2.00 $1.00 50.00 0 1 2 3 4 5 6 7 8 9 10 11 Q demanded Q Supplied. See how this thing shakes out. Maybe this is the point that has been missing, because I thought it was too obvious to state? If you’re going over 100% capacity that’s either typically a situation where they are foregoing maintenance or 100% is simply predefined to be something that isn’t actually the absolute physical limit. I also think that companies not busy being born, are busy dying. (In the longer, the industry might have to bid up wages or the prices of other factors of production to divert them from other industries.) The other article makes no qualification, but if it is simply shipping at 120% of capacity it could be a situation where they are operating at ‘100%’ of capacity’ and they are drawing down inventory, ie imagine a 1000 gallon tank of water where you can only put 50 gallons in per day, but you can widen the spigot at the other end so that you can now take out 60 gallons per day. There’s still an implied opportunity cost, she can’t use that exact metal to do other things, but that cost is minimized now, because the other things are speculative, and the bulk order she’s been paid for. That’s because they are partially paying with inconvenience and queuing time. Are you telling me that the marginal cost of the second dose is higher than that, in the short or long run? Manufacturers of toilet paper, tissues and hand sanitiser are boosting production to keep up with a surge in demand prompted by coronavirus concerns. Is there increasing marginal cost for the company to ramp up production? That would imply an upward sloping marginal cost curve at that point (remember the definition of cost above). Why, just the other day, I was discussing law with a friend who is a constitutional law professor (law is something I study alongside economics, but it is not the subject of my graduate degree the way econ is). Many people already use the commercial quality stuff at work so that should not be a huge hurdle. Look, a profit-maximizing firm will operate wherever he can maximize profit. It should thus be obvious that the short-run marginal cost of producing toilet paper increases with production, which means that the supply curve of toilet paper has a positive slope. She’s been doing this for about 15 years, mostly profitably, although not always. But large companies like Georgia-Pacific or Procter and Gamble, which are incited to maintain the value of their brands (which are worth billions or even tens of billions of dollars), will not yield to this temptation except if the shortage situation gets closer to Cuba or Venezuela. See Chapter 4 here. Therefore, real consumption (C) of toilet paper has not changed. To make the broad, sweeping claim you are doesn’t hold. If a firm is not producing at the increasing portion of the marginal cost curve, we need to ask “why?” We could eliminate the “profit-maximizing” assumption, in which case we’d need something else to motivate firms. A Wall Street Journal story of yesterday (“P&G Toilet Paper Factory Keeps Delivering as Coronavirus Strikes its Town,” April 12, 2020) tells us that the Procter & Gamble plant in Albany, Georgia, increased by 20% its production of toilet paper and paper towels. I don’t have access to the WSJ to read the details, but it is consistent with my story of lower marginal costs until the firm reaches capacity utilization, and then increasing costs beyond that point. Jewelry is on one sense a very competitive market. They will handle all the regulatory, distribution, and selling, all I have to do is get the product to them. Is there increasing marginal cost for the company to ramp up production? The commercial product is shipped on crates in individually wrapped rolls, rather than in brightly branded packs of 6 or 12. Since firms are profit-maximizers, no firm will willingly remain in a market where they are making losses; those resources will be re-allocated to other uses. Walmart distribution centers give a narrow half-an-hour window for supplier deliveries. Dylan is right that a firm can operate on the downward-sloping part of a marginal cost curve. Actually, in your example, at a price of $4, they would lose money no matter how much or how little they produced because their very minimum average total cost is $6.67 per unit. Of course, it isn’t quite that simple, as there are usually things you can do to increase capacity, at least temporarily, without building a new factory. Black markets will develop. But that is still rationing; it is just Antoinettish rationing. Will running all the time introduce a bottle-neck into the supply line that isn’t there when you are running at lower capacity?
