Right now at Primary.guide, you can read the current betting market odds for a “contested convention” and a “brokered convention.”  The definitions are as follows.  A contested convention means that no candidate has 1237 delegates by the end of the last primary.  A brokered convention means that no candidate wins on the first ballot at the convention.

Right now the odds of a brokered convention are 50%.  Note also that the odds of a Trump nomination are 50% as well.  And Trump is the only candidate with any chance of winning a majority on the first ballot (even if he doesn’t get 1237 bound delegates he will be close and no other candidate could combine their bound delegates with unbound delegates to get to a majority.)

Thus, if there is no brokered convention Trump is the nominee.  The probability of no brokered convention is 50%.  Thus the entire 50% probability of a Trump nomination is accounted for by the event that he wins on the first ballot.

In other words there is zero probability, according to betting markets, that Trump wins a brokered convention.

The odds of a contested convention are 80%. That means that betting markets think there is a 30% chance Trump fails to get 1237 bound delegates but still wins on the first round.  I.e. according to betting markets we have the following three mutually exclusive events:

  1. Trump gets to 1237 by June 7.  20% odds
  2. Trump fails to get 1237 bound delegates but wins on the first ballot.  30%
  3. Nobody wins on the first ballot and Trump is not the nominee.  50%

Donald Trump:

You are a lifelong Republican and think Trump is not a conservative. You would never vote for him. You go into the voting both and see Clinton’s name and Trump’s name. What do you do? Either you bite the bullet and vote for Clinton or you abstain. Either way you have increased the probability that Hillary wins – OK not by much but since you are in the voting booth in the first place, you’re not a fully rational voter and so you care about the infinitesimal impact you have. So, you decide to make sure she’s hamstrung by a Republican Congress. You vote for the Republican Congressional candidates.

You would vote for Cruz but suspect he is a bit nuts. You vote for the Democratic Congressional candidates to make sure Cruz is ineffective.

(Kasich would actually be best all round but has no chance of making it.)




Suppose politician C goes negative on politician M. Politician’s M’s support declines..where do his supporters go? If there are just two candidates, they either go to politician C or stay at home. But if there are three or more candidates, they might go to politician A, B, or K etc etc. So, to a first order, it is less profitable to go negative the greater the number of candidates.

This resembles the Holmstrom teams model but with unproductive effort.




From Buzzfeed:

HENNIKER, New Hampshire — In town halls, pizzerias, and high school auditoriums, hundreds of voters are carefully evaluating the three governors who have pinned their presidential hopes on Tuesday’s primary in the Granite State — Jeb Bush, Chris Christie, and John Kasich.

Some have made their choice of the three; others are still undecided. But they all agree on one big thing: The Republican Party needs a strong contender coming out of New Hampshire to take down Donald Trump.

With the stakes so high, these “non-angry voters,” as described by some, are wrestling with whether to ultimately vote for their personal favorite — one of the three governors, or go by the polls in favor of a more practical favorite, Sen. Marco Rubio.

Perhaps the GOP should adopt approval voting as suggested by my colleague Bob Weber where each voter can “approve” as many candidates as he likes.

Of course, Ted Cruz and Donald Trump would disapprove or approval voting.

ISIL has taken war out of the Middle East by bombing a Russian plane and attacking Paris. These attacks follow increased Russian and Western involvement in Syria.

What was the purpose of these attacks? It is useful to examine two polar opposite cases : ISIL’s acts seek to provoke or seek to deter.

If they seek to provoke, the best case scenario for ISIL is that Russia and the West respond by repressing Muslims domestically. This anti-Muslim fervor will generate propaganda that is useful for recruitment. But of course, the attacks will provoke a strong counter-response by France, Russia and their allies in Syria. Finally, a Russia-Western coalition may even come into being. Al Qaeda’s diminished fate then awaits ISIL. A provocation cannot be targeted into only a domestic response and the international response will be so dramatic as to counterbalance any domestic response though, of course, it would also be wise not to give in to the temptation to cave in to anti-Muslim fervor.

If ISIL seek to deter – i.e. they are making us pay a price for increased involvement in Syria and giving us an incentive to retreat – well that’s totally going to backfire. The French, British and Russians are more likely to engage than less as I said above. In this case, ISIL’s strategy would be a complete misreading of the situation.

So, either way, the ISIL strategy is going to fail.

My colleagues are multi-talented:

Uber Drivers tried to organize a strike to demand higher pay.

Uber drivers are competing with each for fares. The smaller the number of other drivers on the road, the greater the chance a driver get business. Also, when demand for rides outstrips supply of drivers, Uber might activate surge pricing to increase supply. Not only does a driver stand to get more business, he gets a higher fare/mile. The incentives to deviate from the strike are huge.

So, in Chicago, during the supposed strike, the number of Uber Drivers on the road was huge. Surge pricing was not activated because it was not necessary.

HT: An Uber driver.

I was on Chicago Tonight very briefly discussing Purple Pricing (see around 4 minute mark).


Good for teaching:

In 2008, the New South Wales government announced plans to build a coal mine here, promising jobs and cheap power. The coal business was booming because of demand from China. The government bought up 177 square miles of land for the mine project, boarding up 114 farms and homes.

Since then, coal prices have plummeted to their lowest level in years and the government has not been able to find a mining company willing to open a mine here. In 2013, the government abandoned its plans to develop the mine and last December appointed Goldman Sachs to sell the land.

By then, the district had lost 95 families, about 10 percent of its population. A sense of loss pervades the town, and residents feel blindsided by forces beyond their control.

Party A steals something of value to Party B and demands a ransom for its return. But once the ransom has been paid, what is to stop Party A from coming back and demanding more?

One mechanism that purchases commitment is reputation. Party A has more ransoms to extract in the future and seeks to be seen as a fair player despite being an extortionist. An interesting example is provided by Cryptowall. This “company” sends an email with a devious attachment, a virus that encrypts your harddrive if you click on it. They demand a ransom in Bitcoin to send the decryption key. The price changes over time.

The fact that they do not take your data means that they cannot come back and demand another ransom for the same data if you pay.

Because the price changes, there can be errors – you pay a ransom of 500 and by that time the price has gone up to 550 and you do not get the decryption key. What to do? A good credit card company would waive a late fee to keep a good reputation and so does Cryptowall. From the New York Times:

Use the CryptoWall message interface to tell the criminals exactly what happened. Be honest, in other words.

So she did. She explained that the virus had struck the same week that a major snowstorm hit Massachusetts and the Thanksgiving holiday shut down the banks. She told them about the unexpected Bitcoin shortfall and about dispatching her daughter to the Coin Cafe A.T.M. at the 11th hour. She swore she had really, really tried not to miss their deadline. And then a weird thing happened: Her decryption key arrived.

You are debating a point with a colleague. Your colleague is wrong but to prove they are wrong you have to use information you know but cannot share. So, you leave things unsaid. Of course, someone who does not know the facts would also leave things unsaid by definition.

The listener knows that silence either conveys the fact that something is known but cannot be said or that nothing is known. Their inference takes the fact that you might know something but cannot say it into account. They should give you the benefit of the doubt. The benefit depends on how likely you are to know things that cannot be said. Hence, if the person leaving things unsaid is senior to the listener, the listener might defer to the speaker. Hence, seniority leads to authority via the inference content from leaving things unsaid.

From a Study in Scarlet:

“I consider that a man’s brain originally is like a little empty attic, and you have to stock it with such furniture as you choose. A fool takes in all the lumber of every sort that he comes across, so that the knowledge which might be useful to him gets crowded out, or at best is jumbled up with a lot of other things so that he has a difficulty in laying his hands upon it. Now the skillful workman is very careful indeed as to what he takes into his brain-attic. He will have nothing but the tools which may help him in doing his work, but of these he has a large assortment, and all in the most perfect order. It is a mistake to think that that little room has elastic walls and can distend to any extent. Depend upon it there comes a time when for every addition of knowledge you forget something that you knew before. It is of the highest importance, therefore, not to have useless facts elbowing out the useful ones.”

A GrAgreement has been semi-signed. Originally, the Eurozone/Germany has offered two debt relief plans for Greece.

Under Plan A, Greece votes on a number of structural reforms and puts E50blln of assets in a privatization fund in return for more bailout money and possible debt relief. Assets are sold off to recapitalize the banks.

Under Plan B, they get a time-out from the Euro and debt relief. Plan B is unpopular with the majority of voters in Greece as they want to stay in the Euro but may actually be better economically depending on the terms. (Will the EC, ECB and IMF actively help to create the new currency and give humanitarian aid? What are the terms of the debt relief?)

But both plans have significant risk: Plan A involves more austerity, declining GDP, Greek Groundhog Day and probably eventual Grexit; Plan B causes the banks to collapse unless the Troika comes up with some active help.

A better plan is variation on Plan B, if you will a Plan G: Germany should leave the Euro. Deutschit will not cause a bank run in Germany as the mark will be strong and no depositors are at risk from a haircut. The Euro will devalue helping not only Greece but Portugal, Spain, Italy, Ireland and Finland. The New Eurozone can bail out Greece and give debt relief. Germany will not have to participate in any of this and this avoids one of the main political problems domestically. There is an economic downside for Germany: the mark will appreciate so exports will be more expensive. But imports will be cheaper so there is less inflationary pressure. Plus Grexit would cause some appreciation of the Euro anyway so even Plan B has that implication.

The main problem with Plan G is it appears to signal the end of the Eurozone. This is a blow to Merkel’s record as Chancellor. But Deutschit makes the rest of the Eurozone stronger as they can deal with the the overvaluation of their common currency. Plan A, Plan B and European economic performance post-2008 already demonstrate that monetary union without political and fiscal union does not work. In fact, Deutschit signals that Germany will take a somewhat costly action to help fellow EC members. It is more likely to stabilize the Eurozone than the other options. It is success for Europe if Deutschit occurs not a failure. Once the New Eurozone has stabilized, Germany can rejoin. Of course, it will have to meet fiscal targets to be accepted by the New Eurozone including Greece. If Germany can’t return because they carry too much debt, that would both be eironikos and cause for epichairekakia (schadenfreude).

Greece and the Troika are engaged in a war of attrition. The player with the higher cost to staying IN vs conceding and dropping OUT is in a stronger position in a war of attrition.

Greece has capital controls, is about to renege on a payment to the IMF, faces an offer from the Troika that is impossible for the Greek government to get through Parliament and the offer consigns the Greeks to more austerity and economic stagnation. They have little to lose from staying IN.

The IMF does not face an existential crisis if it sticks to its guns. The EC suffers from staying IN if there is contagion but they have protected themselves.

So both sides have low costs to staying IN. They have to increases costs on the other side to persuade them to concede.

For the Troika, the strategy is straightforward: they can’t accede to the Greek request to extend the bailout for the referendum, give extra money to banks etc. This is basically what they are already doing.

For the Greeks, the strategy is more surreal: To inflict maximum cost of the Troika, Greece should default on its payments but remain in the Eurozone. Greece is cut off from international lenders anyway and the default will not have any incremental effect on their ability to borrow. With Greece insolvent, the ECB will be the key decision-maker. Do they keep on lending to Greece as they are still technically in the Eurozone? The German Finance Minister says this is the case (via Bloomberg):

German Finance Minister Wolfgang Schaeuble told lawmakers in Berlin that Greece would stay in the euro for the time being if Greek voters reject austerity in a referendum scheduled this week, according to three people present.

Schaeuble also said the European Central Bank would do what’s needed to protect the euro if Greeks voted against the bailout terms in the July 5 referendum

This is ideal for Greece. They keep the Euro and get the debt restructuring they want via default. And other countries in the Eurozone are infected by Greece being in the Euro. If Greece needs anything from the EC, this is an ideal threat point for them.

What if the ECB denies Greece credit? This state of affairs may need to be maintained by the Greek government issuing GrEuros as a medium of exchange. GrEuros can be used to pay the government as if they were Euros. GrEuros will not be accepted outside Greece by wary investors but they would trade internally in Greece. The GrEuro/Euro exchange rate will float. There is less risk of contagion here as GrEuros are not the same as Euros. Eventually GrEuros will become drachmas.

All these tactics will prolong the war of attrition. They will mask the bigger problem: How sustainable is the Eurozone with a monetary union but no political union?

I found this discussion paper by Stergios Skaperdas offered a useful perspective on the crisis. Here is a passage on default:

If Greece had defaulted in early 2010 Greek debt could have become sustainable in the long run with a writeoffs imposed on bondholders of considerably below 50% of total debt. The country would have had to borrow internally, perhaps issue IOUs (as it has done already), and impose a few modest cuts. The effect of such a policy would have been mildly recessionary.

What was done in 2010 instead by the troika was to provide Greece with loans so as to cover its budget deficit without default, in exchange for increasingly draconian budget cuts, tax increases, and institutional changes of dubious value. The effect of this policy was a fast downward spiral of the economy. Since debt kept increasing and the country kept getting poorer fast, debt was becoming ever less sustainable. Thus, the second bailout in 2012 restructured Greek debt, with the main losers being Greek pension funds and Greek banks. The Greek state had to borrow 50 billion euros just to recapitalize the banking system and continues to have to cover the losses of the pension funds (in addition to cutting pensions, cutting health expenditures, and increasing retirement ages). The continued contraction of the economy, deflation, and a few additional loans from official sources have brought the debt-to-GDP ratio close to 180%, the highest it has ever been.

Now, default would be considerably more difficult both because Greek public debt is under English law and because 80 percent of it is official and owed to official sources (the IMF, the ECB, and other Eurozone member countries). Yet, that debt is unsustainable and there is virtually no chance it will be fully paid back. Default is still a taboo but it is bound to occur in one way or another, regardless of how it is named.

Airlines are making it more difficult to do comparison shopping:

Airlines are increasingly pushing and prodding travelers to book flights through their own websites, where they can sell more services like in-flight entertainment and add-ons like hotel reservations. They also bypass paying a commission to websites that book plane tickets.

For consumers, this means that the hunt for the lowest fare has become more difficult as the number of places where they can comparison-shop has dropped. In many cases, they just give up.

Sure airlines can sell add-ons and cut out the middleman when people buy from their websites but they also have more wiggle room to increases prices if price comparison is difficult. Here is the abbreviated logic from our description of Diamond-Mortensen-Pissarides 2010 Nobel:

Peter Diamond has a classic paper A Model of Price Adjustment in the Journal of Economic Theory in 1971.  Diamond shows that even an infinitesimal search cost can lead to monopoly pricing rather than competitive pricing because of a hold up problem.  Suppose there is no search cost and two firms are selling an identical good.  The logic of (Bertrand) competition means they will both end up pricing at cost.  At any higher price, one firm can undercut the other and capture the entire demand rather than half the demand and double its profit.

Instead suppose there is a small search cost e>0 a consumer must pay to discover the price.  Pricing at cost is no longer an equilibrium – one firm can raise its price by almost e. The consumer discovers the higher price once he enters the store.  But going to the other store to get a lower price involves a transactions cost of e anyway.  So, it is better to submit to hold-up and pay the higher price.   This logic obtains at all prices lower than the monopoly price.  At that point you do not want to raise the price any more as consumers simply stop buying at a rate than makes further price increases lead to lower profits.   So, a small search cost reverses the intuition about pricing completely.

Cato Unbound is running a discussion with this topic.  Alex Tabarrok and Tyler Cowen kicked things off by suggesting that technological advances are ending asymmetric information as an important feature of markets.  My response, “Let’s Hope Not” was just published.  Josh Gans and Shirley Svorny are also contributing.

Suppose there are two bakeries which make wedding cakes and other baked items. The pastries from one bakery are pretty much the same as those from another so the baked goods market is quite competitive and margins and profits are thin.

The legislature passes a law allowing businesses to select which customers they will serve and which they will not.

One bakery, bakery A, decides to be selective and the other, bakery B, decides to be non-selective. The fact that bakery A has become selective becomes public knowledge either because the bakery advertises this fact or through word-of-mouth.

Does economic competition eliminate discrimination? This is the question.

Customers who abhor bakery A’s selection criterion boycott bakery A even if in other respects it would be convenient to just get a doughnut from bakery A. So, bakery B, gets additional business it did not get before.

Surely bakery A is suffering and hence should drop its ill-advised selection policy? Not so fast.

Some customers favor bakery A’s policy and they actively seek out bakery A’s products (the “Chick-fil-A” effect). So bakery A loses some customers but gains others. Moreover, the customers it gains are more loyal than the customers who enjoyed its products before it adopted its policy. Similarly, the customers bakery B gains are more loyal too.

Hence, product differentiation has increased because of bakery A’s active adoption of its policy and from bakery B’s decision not to adopt the same policy. The logic of competition now implies both bakeries will make more profits than they did before.

So, discrimination is not driven out by competition between firms. If anything it is reinforced by competition. This stands in contrast to Becker’s model where competition decreases discrimination in employment. (There is some way to make these models consistent by having workers have preferences over co-workers. Maybe someone already did this model?)

Without political or legal intervention, competition will not drive out discrimination.

Forty-seven Republican Senators signed a letter to the Iranian leadership claiming that any nuclear non-proliferation treaty signed by President Obama could be vacated at the stroke of a pen by the next President. What is the impact of their tactic on the probability of the deal being signed?

There are many effects but here are four key ones:

1. The Iranians now get further confirmation that President Bush III will be tougher than President Obama. The deal on the table is the best they are going to get. This makes them more likely to sign.

2. Democrats who are skeptical of the deal with now rally round the President, as they did after the surprise Netanyahu speech. This makes a deal more likely.

3. The Iranians now get further confirmation that the deal may fall apart under next administration. This makes it easier for them to renege in the future if circumstances dictate – they can more credibly blame the U.S. for being untrustworthy. Their citizens will not blame them if they exit the agreement as the Iranian leadership can more credibly blame the U.S.

Russia and China can trade with Iran with less international condemnation as the U.S. can be more credibly faulted for the deal falling apart. This makes a deal more likely.

4. The “no deal” option just got better too for reasons outlined in 3. Iran can blame the U.S. for not agreeing to the treaty and try to persuade Russia etc to break sanctions. This makes “no deal” more attractive relative to “deal” and makes the deal less likely. It could also mean that the deal the Iranians now get is improved to reflect their better outside option. If the deal is already better than even the improved outside option, the improvement will have little effect on the chance of a deal.

So, unfortunately, the net effect of the letter on the probability of an agreement is ambiguous. But even if the letter makes a deal less likely, it makes it less likely by making Iran stronger.

An excellent survey from the White House. Useful for teaching. For example:

Even if sellers do not wish to randomize prices across potential buyers at a point in time, it is often possible to collect similar data by raising and lowering prices for all customers over very brief time intervals. For example, if customers who arrive at a website at 10 am face a lower price than those who arrive at 10:15 am, and buy correspondingly more of a given product, the seller has discovered valuable information about the demand curve without technically offering different prices to its customers. To provide an example indicating that this phenomenon happens, the following chart shows two years of prices for a particular children’s toy on Amazon.com. While these frequent price changes are not necessarily experiments, they will certainly provide information about consumer demand for this item.


From NYT:

You recently did a tour with $20 tickets and $4 beers. Is it your goal going forward to keep it affordable? Yeah. Even if you’re not a big fan, you’re like: “Let’s find something to do tonight. It’s $20 to see Kid Rock. I like one of his songs, whatever!” The scary part is, you’re going to find out who your audience is, very fast. If nobody comes for $20, it’s about time to hang the hat up.

Another reason why companies do not cut prices when demand tanks? They are worried about what they will find out about themselves. If you keep the price high and no-one buys, you can console yourself that sales would have been high if you had cut the price. If your price is low and no-one shows up, it is harder to rationalize that your product is popular.

According to the NYT, the Saudi’s (the principal) are thinking of using the oil price to incentivize Russia (the agent) to stop supporting Iran:

Saudi Arabia has been trying to pressure PresidentVladimir V. Putin of Russia to abandon his support for President Bashar al-Assad of Syria, using its dominance of the global oil markets at a time when the Russian government is reeling from the effects of plummeting oil prices…Saudi officials say — and they have told the United States — that they think they have some leverage over Mr. Putin because of their ability to reduce the supply of oil and possibly drive up prices.

There is one countervailing effect that has been foreseen and dismisssed:

American and Arab officials said that even if Russia were to abandon Mr. Assad, the Syrian president would still have his most generous benefactor, Iran. Iranian aid to the Syrian government has been one of the principal reasons that Mr. Assad has been able to hold power as other autocrats in the Middle East have been deposed.

And as a major oil producer, Iran would benefit if Saudi Arabia helped push up oil prices as part of a bargain with Russia…..

But the military aid that Russia provides to Syria is different enough from what Damascus receives from Iran, its other major supplier, that if “Russia withdrew all military support, I don’t think the Syrian Army could function,” a senior Obama administration official said.

But there is a bigger one: Iran has a nuclear program that the US (and Saudi Arabia?) would like to undermine. Low oil prices and sanctions are the stick that the US has been using to get Iran to the negotiating table. An increase in the price of oil price takes away the stick etc etc. Hope the absence of any mention of this in article does not imply someone is not thinking it through.

Here are the prices you see if you access the Kiwi Rail website from Chrome in the US:

Screenshot 2014-11-26 14.45.28

Note the blank space between the trip name and the prices. What could be there? Google “Kiwi Rail discounts” and find information that suggests accessing the Kiwi Rail website via a browser with a New Zealand IP address. When you do that, you find:

Screenshot 2014-11-26 16.10.43

Why are people physically in New Zealand getting better deals? You can tell a demand elasticity story: New Zealanders have cars and access the website from browsers with NZ IP addresses. Their demand is more elastic than that of foreign tourists. So, price lower to people buying from NZ. You can tell the reverse story: Many tourists in NZ buy when there. Their outside option is flying and buying flights late is expensive. Tourists make up the vast majority of train travellers in NZ. People buying from abroad are also tourists but they are buying early and can find cheaper domestic flights. So their demand is elastic.So price high for people buying from NZ IP addresses but low for people buying from foreign IP addresses.

Whatever the truth of the matter, it is quite interesting to see this kind of price discrimination by Kiwi Rail. God knows what Amazon is doing in comparison!

Here is an article on the latest Michelin stars for Chicago Restaurants. The very nice thing about this article is that it tells you which restaurants just missed getting a star. As of yesterday you would have preferred the now-starred restaurants over the now-snubbed restaurants. But probably as of today that preference is reversed.

Any punishment designed for deterrence is based on the following calculation.  The potential criminal weighs the benefit of the crime against the cost, where the cost is equal to the probability of being caught multiplied by the punishment if caught.

Taking surveillance technology as given, the punishment is set in order to calibrate the right-hand-side of that comparison.  Optimally, the expected punishment equals the marginal social cost of the crime so that crimes whose marginal social cost outweighs the marginal benefit are deterred.

When technology allows improved surveillance, the law does not adjust automatically to keep the right-hand side constant.  Indeed there is a ratchet effect in criminal law:  penalties never go down.

So we naturally hate increased surveillance, even those of us who would welcome it in a first-best world where punishments adjust along with technology.

From WSJ:

Even for the airline industry, cheaper oil may not be all good, analysts say, if carriers see it as an opportunity to increase capacity and then lower fares to fill empty seats, some analysts say. Hunter Keay of Wolfe Research LLC recently noted that airlines did just that during a previous oil slump in 2010. “Then oil prices went right back up again, as they tend to, and 2011 stunk,” he wrote.

Paul Krugman has an op-ed today where he argues Amazon is abusing its power:

Which brings us back to the key question. Don’t tell me that Amazon is giving consumers what they want, or that it has earned its position. What matters is whether it has too much power, and is abusing that power. Well, it does, and it is.

Amazon is attempting to negotiate lower prices from the publisher Hachette and is slowing down sales of Hachette books on amazon.com in an attempt to force their hand. This is the main evidence.

But this kind of bargaining leads to lower prices for consumers not higher. Hence, from the perspective of welfare it is actually good. It is akin to the argument for reducing double marginalization via vertical integration. Double marginalization occurs because the primary producer (here Hachette) and the retailer (here Amazon) BOTH add a margin on to costs to maximize profits. Welfare would be higher and prices lower if they vertically integrated so some externalities are internalized. In fact, here is Krugman in 2000 explaining why breaking up Microsoft into Windows and Office is a bad idea:

In the last few days the Justice Department, outraged by the lack of contrition among Microsoft executives, has apparently decided to seek a ”horizontal” breakup of the software company — that is, to split it into one company that sells the Windows operating system (the upstream castle) and another that sells Microsoft Office and other applications (the downstream castle)….

even if you believe that Bill Gates has broken the law, you don’t want to impose a punishment that hurts the general public. And even strong critics of Microsoft have worried that a horizontal breakup would have a perverse effect: the now ”naked” operating-system company would abandon its traditional pricing restraint and use its still formidable monopoly power to charge much more. And at the same time applications software that now comes free would also start to carry hefty price tags.

As we know from ECON 101, integration is just one way to internalize externalities. Another would be for the retailer to negotiate lower prices from the producer so they are closer to production costs. Another would be for the producer to force the retailer to charge a lower margin. As both sides try to negotiate such deals which are good for them but bad for the other side, there is a war of attrition as we see currently. Sure Amazon’s tactics may be a bit crude but this is the typical kind of negotiation that lowers input costs and eventually prices. Hachette’s tactics are harder to observe but I would bet they are not so different.

(Update Oct 21: Spelled out some more details!)

You are trying to convince others that the product you are selling is high quality. Your target audience is concerned that the product is low quality. So your sales pitch should be credible – it should be convincing that the sales pitch would not be made by someone who is selling a low quality product.

Your target customers are also salesmen. They sell their own products and use a certain kind of lingo when they pitch. They use this lingo even when they are selling bad products.

Since you are pitching a product to them, you are tempted to use language they understand. But here is the problem: they know they use this language even when are makin’ stuff up. If you use that language, they suspect you are makin’ stuff up. So they do not believe you.

So, you have to come up with your own jargon, one your customers are unfamiliar with. Of course, back up your pitch with facts and logic. But if you pitch seems like BS, the evidence will have to be all the stronger to help you. If you have no facts and logic on your side, only a unfamilar pitch has any chance of succeeding.

Norway and Liberia (somewhat) internalize externalities:

Norway will give Liberia up to a hundred and fifty million dollars in aid, in exchange for which Liberia will work to stop the rapid destruction of its trees.

Liberia has much of what remains of West Africa’s rain forest, but logging is rampant. The initiative is not an act of charity but a trade: Liberia gets income, which it needs; Norway gets to preserve biodiversity and take a small step against climate change. A similar deal that Norway struck with Brazil years ago helped slow deforestation there. Economists call arrangements of this kind “payments for ecosystem services,” and they follow a rationale known as the Coase theorem. In 1960, the economist Ronald Coase argued that bargaining between parties could, under certain conditions, produce a mutually beneficial and efficient solution to problems like pollution.

Brazil and US subvert efficiency via transfers:

When the WTO’s Appellate Body upheld Brazil’s claim that U.S. cotton subsidies were depressing world prices and hurting Brazilian cotton farmers in the process, the United States did not amend its subsidies to make them compliant. Rather, it agreed to pay Brazil $147 million a year for the privilege of continuing to subsidize its own farmers in a WTO-inconsistent way. This week, the United States reached another settlement, buying Brazil’s peace once more, this time to the tune of a $300 million lump sum payment.
