RBA and Treasury at war

by Mark Crosby | Filed Under Economics | 3 Comments

I’ve been unable to read properly for a few weeks, but a few things that I have been able to hear are worth me writing about this week. Firstly, the IMF have suggested that Australia introduce capital gains tax on housing, and also allow mortgage interest deductability. This is a really dumb idea, but will leave for tomorrow. And the national accounts come out this week, with forecasters now expecting 2nd quarter GDP growth in Australia of around 0.7%. Not bad, but if that rate continues (and on that I’m skeptical) unemployment will still trickle upward. Which leads to the fact that the RBA are now expected to raise rates before year end, while the government wants to continue with the stimulus package. This is Reagan and Volcker all over again, and is likely to end equally badly. It makes much more sense to slow down the rate of fiscal stimulus, and to hold rates where they are as the signs of recovery continue. Stimulatory fiscal policy and a tighening of monetary policy makes no sense – particularly in a 1.5% inflation environment. See chapter 2 of Sargent’s “Rational Expectations and Inflation” for more on the Volcker/Reagan episode.

Grazing, Goods and Girth: Determinants and Effects (gated, sorry) 
Daniel S. Hamermesh
Using the 2006-07 American Time Use Survey and its Eating and Health Module, I show that over half of adult Americans report grazing (secondary eating/drinking) on a typical day, with grazing time almost equaling primary eating/drinking time. An economic model predicts that higher wage rates (price of time) will lead to substitution of grazing for primary eating/drinking, especially by raising the number of grazing incidents relative to meals. This prediction is confirmed in these data. Eating meals more frequently is associated with lower BMI and better self-reported health, as is grazing more frequently. Food purchases are positively related to time spent eating–substitution of goods for time is difficult–but are lower when eating time is spread over more meals.

More on broadband caps

by Joshua Gans | Filed Under Broadband | 8 Comments

My article in The Age on broadband caps got a bit more attention than I had bargained for. There are several themes that I wanted to follow up on. My starting point was high bandwidth costs in Australia. I suggested based on my reading of those in the known (for instance, this great piece by Ben Edelman in the Journal of Economic Perspectives) that bandwidth costs are now low — of the order of 15 cents per GB. If the Australian broadband market is working like a competitive industry then usage charges would reflect those costs. Instead they are 1000 times higher at 15 cents per MB.

First, what is the cause of high bandwidth costs? Are they really that high for Australian ISPs? Some suggested it was about international capacity. But if that was true, we know that capacity has been growing (click here). Why has the 15 cents per MB charge stuck? Others suggested that the wholesale providers (Telstra, Optus and some others) were keeping wholesale prices at that level. That could well be true but again, why are the wholesale providers doing that? Surely they want to compete for wholesale market share too. The final issue — that I hinted about — was congestion. But at these ridiculous prices surely more than just a few smaller ISPs would offer plans that shaped that congestion. Why can’t Telstra or Optus do that? It just doesn’t make sense that they are facing those constraints. They don’t even have congestion pricing for businesses.

My point was that something else is going on. To explain Telstra, Foxtel looks like the elephant in the room. To explain the others, it is a harder task. To me, the idea that these are real costs of 15 cents per MB just doesn’t add up.

Second, shouldn’t an economist be in favour of usage pricing? This came up over at catallaxy and in the comments there. To which I respond. Absolutely, and I have favoured usage pricing in all manner of circumstances especially where people are taking actions that are imposing costs but they aren’t paying a price for it.

In my article, I was not suggesting that broadband use be free — just that it reflect true costs. 15 cents a MB is not usage pricing. It is non-usage pricing. There is no-one who (knowingly) pays that charge for use. The highest ‘free’ allowance on BigPond is 60MB per month. They may be users who want consume more than that and pay the cost (more like 15 cents per GB or even $1.50 per GB — 10 times more) for the privilege. They are not served by this. The 15 cents a MB charge is Telstra’s way of saying we don’t want to sell you any more bandwidth this month. Come on. Could it really be that they don’t want to do that in a normal business? Can’t imagine.

So to those who think 15 cents a MB is reasonable, produce ONE PERSON who knowingly purchases say, 100MB, or 0.167% of the top Telstra allowed monthly usage of this. If there isn’t anyone, you can’t claim this is usage pricing. To do so, gives the whole concept we fight everyday for a bad name.

Chicago school refuted

by Joshua Gans | Filed Under Economics | 2 Comments

From The Onion:

CHICAGO—Though the stock market remains shaky and consumer spending has reached a standstill, the U.S. economy is apparently still robust enough to produce nearly half a dozen television shows about cake. “This flies in the face of basic economic theory,” University of Chicago economist John Holloway said Friday, referring to such programs as Ace Of Cakes, Cake Boss, and Last Cake Standing. “Despite the worst recession in a generation, these shows somehow make enough money to pay for sets, celebrity hosts, producers, camera crews—not to mention the cakes themselves—all so people can see a dessert that looks like a Dr. Seuss character.” Holloway made it clear, however, that no known mathematical model has yet been able to explain why in the hell anyone would watch those Real Housewives Of Whatever shows.

A portfolio of portfolios

by Sam Wylie | Filed Under Economics | 1 Comment

An example of the ‘portfolio of portfolios’ problem appeared in the AFR on Tuesday.  An article by Ben Wilmot discussed the purchase of a shopping centre in Perth by Colonial First State Asset Management for $450 million.  The article considers what CFS Asset Management will do with its new property as follows.    “It is uncertain whether the centre is destined for the listed CFS REtail Property Trust, which reported last week, or whether it will be kept in an unlisted vehicle.”

In this situation an asset management firm (CFS) manages more than one portfolio on behalf of different investors (a listed property trust and unlisted trust) and it must decide which of those funds to favour.  If CFS believes that the shopping centre is worth substantially more than $450 million then it can favour the investors of either fund, but not both.  CFS has an interest in this decision.  CFS will receive management fees on the $450 million, but those fees will differ across the two funds.  Moreover, the recent investment performance the two funds will differ.  So CFS could choose to favour the poorer performing fund to prop up its performance, or favour the better performed fund, possibly building a “star” fund that attracts a lot of new money.  There is no suggestion in the AFR article, or here, that CFS has acted improperly in any way.

I have a new paper out today, looking at the impact of the Australian 2009 household payments on expenditure. It uses a poll question contained in the June ‘ANU Poll’. Here’s the abstract (click on the title for the full paper):

How Much Did the 2009 Fiscal Stimulus Boost Spending? Evidence from a Household Survey
Andrew Leigh
Using survey evidence, I estimate the impact of a $12 billion package of household payments delivered in Australia between March and May 2009. Forty percent of households who said that they received the payment reported having spent it. This is approximately twice the spending rate that has been recorded in surveys assessing the 2001 and 2008 tax rebates in the United States. Using an approach for converting spending rates into an aggregate marginal propensity to consume (MPC), this is consistent with an aggregate MPC of 0.41−0.42. Since this estimate is based only on first-quarter spending, it may be an underestimate of the longer-run impact of the package on consumer expenditure.

Surveys aren’t the ideal way of estimating expenditure, but in my view they’re superior to looking for sudden movements in quarterly macro figures, which has been much of the debate so far.

You know the story of the two guys who are being chased by a lion. One says to the other “We are going to die. We can never outrun this lion.” His friend replies: “I don’t have to outrun the lion. I only have to outrun you.”

A recent paper* turns the modern spotlight of statistics onto that pressing issue of how best to survive a big cat attack. The authors analysed data from 185 puma attacks on humans in North America over more than 100 years. The response was severity of injury, ranging from no injury to death. The predictors were age, group composition and behaviour. I am not sure about age but I am guessing that you shouldn’t go walking by yourself in puma country for a start. The modern data crunch used to reveal the elusive truth was multinomial regression.

It turns out that age had no effect on injury severity. Once the puma gets his claws into you, you are pretty well fu…d, well in serious trouble however old you are.

There is confirmation that if you are in a group you have less chance of injury – just as the guys in the humourous story reasoned from first principles. But the severity of injury is not reduced by larger group numbers. Your mates are obviously too busy climbing up the nearest tree to distract the puma from snacking on your wobbly bits.

It also appears that your behaviour influences the chance of serious injury. Specifically, it is found that if you stand still and wait for the puma to attack you then you have a higher chance of injury (74%) then if you run like hell (50%). And it doesn’t really matter how fast you run – presumably because the puma can run faster than you or Usain Bolt.

So, if you see a puma attacking then you should run. Who would have thought! ** This is science and modern number crunching at its best – pushing the frontiers of human knowledge and saving human lives.

** OK, I am being a bit hard on the authors. Actually, conventional wisdom and some wildlife agencies advise against running. The California Department of Fish and Game says on its Web site, in part: “Do not run from a lion. Running may stimulate a mountain lion’s instinct to chase. Instead, stand and face the animal.”

Broadband caps in The Age

by Joshua Gans | Filed Under Broadband | 19 Comments

I got in one of my — let’s complain about broadband usage cap — moods this weekend. The result is the piece (over the fold) in today’s Age.

ISPs should pay no mind to the cap

Joshua Gans, The Age, 25th August 2009.

ONE of the great anomalies of the Australian broadband industry is the existence of usage caps, which around the world are virtually non-existent.

In the US, some internet providers have talked of a 250 gigabytes-a-month limit. That has led to consumer outrage that forced those providers to desist lest they lose customers. This is despite the fact only 0.003 per cent of US broadband users exceed that level – just 0.21 per cent exceed 100GB.

To an outsider, the Australian system seems very strange. Telstra boasts a basic package on its BigPond Cable Extreme network that, for $39.95 a month, gives 200 megabytes in usage. At Telstra’s boasted 30MB a second speeds, that amounts to a minute of high-quality video downloads. After that you pay 15¢ a megabyte. It is hard to imagine that being an option for consumers.

But even its Liberty plan, which costs $69.95 and offers 12GB a month – after which the extreme speed is slowed to the speeds of last century – only allows you 20 hours of video watching a month, provided you do nothing else. That’s about 45 minutes a night.

No wonder so many people do their YouTube watching at work.

Had the US and rest of the world had similar practices, requiring users to carefully watch their megabytes, YouTube and similar services would never had been conceived, let alone put into practice. Perhaps the carriers would have hosted content, under the cap, but then we would be in a world where they decided what we saw rather than the demonstrably better one where that choice is truly free.

There are costs to bandwidth. But rather than being 15¢ a megabyte, they are in the order of 15¢ a gigabyte – or 1000 times less. So if you are using 500GB a month, you are costing your carrier $75 a month. It seems reasonable that you pay for it. But, in Australia, if you want to use 50GB a month, you’ll pay $2.60 a gigabyte to Telstra. Paying for bandwidth is fine. Getting gouged for it is another matter.

It is not just Telstra, although it has a special role. No internet provider in Australia offers a plan like they do in the US. The best ones are cheaper than Telstra but offer more by dividing between peak and off-peak use.

They have not tried to grab market share by going for it and freeing people from dreaded usage monitoring.

Why isn’t competition working here? It is difficult to say but consider what would happen if a smaller provider lifted its cap to 250GB and charged 15¢ beyond that. It would attract a disproportionate share of those who would use that much. That may represent a small part of the market but a large part of its customers. Add to that the potential congestion caused by such usage – if concentrated in the evenings – on the equipment installed in Telstra exchanges, and that 15¢ a gigabyte may be something much larger.

This is a problem that Telstra likely does not face. But it does face conflicts that might give it pause when lifting caps.

For instance, a higher cap moves video watching online and out of the living room where Foxtel boxes reside. That is a cost it faces that others do not. But it is a cost borne of choice, the choice to be integrated with Foxtel.

We are told that the new management of Telstra is more open and ready to meet the challenges brought about by the national broadband network. The NBN will have the capacity to break through usage caps. But why wait eight years?

There is an opportunity for Telstra to demonstrate its new responsiveness and get rid of this anachronism. It could lift its Liberty plan to 100GB and likely face few additional costs if it charged 15¢ a gigabyte. It would send a strong signal to markets.

For others, there is a similar route. Smaller providers need not offer high-cap plans widely, but, for example, as an employee deal with businesses they also serve.

Think about it. Employees would be offered plans that gave them incentives to watch YouTube at home rather than at work. Employers would be happy and there would be only a marginal increase in traffic for the service provider as usage moved from work to home.

There is a way out of tight usage caps that stifle appropriate internet use. These will not be costly given international experience, but will open up more services to broadband usage. The NBN will provide this, but Australians shouldn’t have to wait that long.

Switching to the correct side

by Joshua Gans | Filed Under Game Theory | 1 Comment

A coordination game is one where everyone benefits from choosing a similar strategy but there are many such strategies so the issue is how coordination occurs. Usually, we think of which side of the road you drive on as a legal issue but it is actually a coordination issue: we drive on the same side as everyone else otherwise things would be bad if we took liberty into our own hands.

With that it is really interesting when a country decides it is in the ‘wrong’ equilibrium and wants to change to another. Samoa has decided just that and will early morning on 7th September switch driving from the right to the left hand side of the road. Why?

The main reason for Samoa’s switch is that two of its biggest neighbors, Australia and New Zealand, drive on the left-hand side, whereas Samoa currently drives on the right, as in the U.S. By aligning with Australia and New Zealand, the prime minister says, it will be easier for poor Samoans to get cheap hand-me-down cars from the 170,000 or so Samoans who live in those two countries. It could also help more people escape tsunamis, says Mr. Tuilaepa.

Tsunamis? OK, that is just a reflection of clear dissent on this issue and political handwaving. There’s more.

In a TV address about the road change last week, the prime minister warned that “the only thing to fear is fear itself.”

The reasons for change seem weak (e.g., the ability to buy Australian cars!). Sweden switched in 1967 but at least you could drive somewhere.

Oh yes, and if you think that there wasn’t enough cost, 7th September is a Monday. It is hard to imagine a worse day of the week to switch things. That said, the Government did realise that and declared the Monday and Tuesday a holiday. It also has set up a training area now so Samoans can practice driving on the left. Of course, that has only illustrated the issue they face.

One recent Sunday morning, a bus was seen barreling down the right side of the road in the training area, the driver apparently oblivious to the fact that it was the wrong side. After nearly running head-on into a sport-utility vehicle, the bus driver swerved then returned to the wrong side of the road and chugged on.

I think the 7th September is the day to watch for South Pacific YouTube activity.

ETS in The Punch

by Joshua Gans | Filed Under Environment | 1 Comment

I have an article in The Punch today on costs and the ETS. Not sure about the title!

How and why the ETS could cost you

Joshua Gans, The Punch, 24th August 2009.

In 2007, Chris Goodall contended that walking may cause more environmental harm than driving.

The Australian's KudelkaThe Australian’s Kudelka

A noted that a 5km drive would add 1kg of carbon to atmosphere while a walk would seemingly add nothing if you just looked at its direct effects. However, Goodall contended that for many people, they would need more energy to sustain a regular 5km walk. To make up the 180 calories would likely generate 3.6kg in carbon emissions. The trade-off wasn’t even close.

What is significant is that Goodall wasn’t some member of an anti-environmental think tank but himself a strong environmentalist and the author of How to Live a Low-Carbon Life.

And it was he who was suggesting, contrary to one of Al Gore’s dicta in An Inconvenient Truth, that substituting driving for physical transportation might not be environmentally-friendly at all; even if it is friendly to your physical health.

I’m sure we can argue of the details of Goodall’s calculations and make sure we don’t come to a resolution as to whether walking should be banned or not. But to an economist, this whole issue encapsulates why we should have an environmental trading scheme (ETS) like the Government’s proposed Carbon Pollution Reduction Scheme (CPRS).

In discussions of the economic costs of climate change policy, there is a great deal of guesswork. For instance, there have been forecasts of how such policies will impact on the price of food or the cost of energy.

This usually rings all manner of alarm bells about the overall economic impact of the CPRS.

But, each and every one of these makes assumptions not only about how people’s behaviour might change when faced with higher costs but also how a price on carbon would percolate through the production chain and drive the prices consumers pay.

For example, an increase in electricity prices is going to impact more on businesses that use lots of electricity.

For instance, canned goods would be impacted upon in the making of the can itself, the mining and processing of minerals to make the metal in the can, the processing plant that puts the food in the can and then on the conditions in the supermarket that distributes it to consumers.

Will the price of such goods go up by the full price increase in electricity? It is unlikely.

For starters, canned goods require less energy at the supermarket end than fresh food that impacts on climate in the supermarket itself.

But even along the way, the choices food providers made as to how they processed food and constructed cans were based on an electricity price without carbon. Add that carbon price and they may well change their practices.

The point is that it is impossible to tell how all of this will work its way through and sort itself out in terms of prices to consumers.

To be sure, it could be a disaster in that businesses and people have limited choices to move away from high carbon consumption ways.

But every shred of experience with economic impacts of this kind tells us that choices are much wider than what we had previously thought.

When faced with a higher expense, people find no end of ways of avoiding that expense. And each time they do, they soften the economic impact of the CPRS.

The only thing we know for certain is that unless we set a carbon price (or the means of getting one), we will not find out precisely what can be done. It will take time.

But again, that is the point. We need to get started right away.

Occasionally, I get blog post requests and more occasionally I respond. This is one response from a reader who is wondering what I made of the whole ‘public option’ debate in the US over health insurance. This is actually something I worked in for Australia back in 2003 (or thereabouts) and was part of Finishing the Job.

As I understand it there are several problems facing the US system. First, there are 50 million uninsured. Second, many of those who are insured have deals that might mean they are actually uninsured as treatments and even coverage may be denied when they come to claim it. Uwe Reinhardt calls this ‘unsurance.’ Third, too much is tied to employment. Fourth, it is hard to work out what is going on and so competition may be impeded. Finally, it isn’t clear the system with these problems is even economical (i.e., in maximising health per dollar spent).

The proposals cover various things. The first is to set-up an exchange that makes choices easier for consumers. We don’t have that here but anything that improves transparency is, prima facie, not a bad idea. The second is to launch a public scheme in that exchange. The idea is that will be both cheaper and less discriminatory than private plans and so will be able to close some of the uninsured gap. The issue here is that it will surely cost more money because you are paying for more health (which is, by the way, not a bad idea) although if there is a competition issue in private insurance, this effect will be muted.

To the outside eye, this all seems messy. For instance, if a public provider can solve the ‘unsurance’ problem surely with appropriate regulations, private providers can do so to. In Australia, this is done through community rating and last time I looked the industry survived. In addition, universality can be solved be appropriately extending Medicare. Finally, there is a rationale for breaking the whole employment-based system by taxing the benefit while at the same time reducing payroll tax — that way, insurance isn’t likely to be tied to an employer.

That said, when you think about it, the optimal system – whereby everybody in insured to some level of treatment with those treatments reimbursed at a set rate with private coverage being allowed to offer additional treatments, quicker treatment and fancier surrounds — would be really hard to jump to. The transition would be painful especially without publicly-owned hospitals to catch the bits that are missed while the private sector re-organises itself around a new model. When you start to consider transitional issues, the public option — for all its messiness — starts to look more attractive.

[Update: Another interesting perspective]

Apple responds to the FCC

by Joshua Gans | Filed Under Economics | 2 Comments

The Federal Communications Commission asked AT&T, Apple and Google to answer some questions on why Apple rejected the Google Voice app. They have done so now with AT&T denying knowledge while Apple claims it is still considering it due to issues of compatibility with its interface. But the interesting bit of their response is this:

There is a provision in Apple’s agreement with AT&T that obligates Apple not to include functionality in any Apple phone that enables a customer to use AT&T’s cellular network service to originate or terminate a VoIP session without obtaining AT&T’s permission. Apple honors this obligation, in addition to respecting AT&T’s customer Terms of Service, which, for example, prohibit an AT&T customer from using AT&T’s cellular service to redirect a TV signal to an iPhone. From time to time, AT&T has expressed concerns regarding network efficiency and potential network congestion associated with certain applications, and Apple takes such concerns into consideration.

Now just so we are clear. VOIP usage is not a network congestion issue. So blocking Skype and the like outside of WiFi is strange. The reason is this: the iPhone has always had YouTube front and centre. That is the bandwidth hog not to mention streaming services such as Pandora. VOIP is nothing compared this. And it is not only AT&T. Australian carriers appear not to allow similar things.

I get the feeling the FCC didn’t ask the right questions. What it wants to know whether the exclusivity deal with AT&T brings with it incentives that modify Apple’s behaviour in terms of the applications it approves. The possibly correct response is that it is nothing to do with exclusivity and is just something imposed by all carriers even where there are no such deals. Alas, we didn’t get an answer because the FCC didn’t get to the issue.

What year is it?

Imagine that you were speaking to an ordinary man in Western Europe in the year 1500.  If you asked him to describe his identity, the very first thing he would say is that he was a Christian.  Then he might identify with his  village and family.  His world view would be necessarily local.  He would believe that all authority to explain the creation and nature of the world rested with his religion.  He would be confounded and disturbed by the idea of democracy or liberalism.   He would consider women to be essentially the property of men. 

By 1750 much was changed.  The Renaissance (beginning in Italy in the 1350s) reintroduced to Europe classical learning.  The democratic ideals of ancient Greece and the example of the Roman Republic and Roman law were immensely influential on the emerging polity.  The Renaissance also promoted humanist teaching and civic virtue.   The Protestant Reformation rested power from the established church.  Crucially, the Reformation elevated the role of individuals relative to society by insisting that each individual had a personal relationship with God regardless of institutional arrangements on Earth.   Most importantly, The Enlightment took authority for explaining nature from the Church and gave it Science.  Enlightment rationalism swept away millenia of embedded ideas on how society should be structured and put the West on an unstoppable path to liberal democracy. 

Imagine now that you were speaking to an ordianry man in Helmund Province in the south of Afganistan today.  His views the world and society would more likely remind you of the Europe of 1500 than the Europe of 1750.  Read more

Counterfactuals

by Joshua Gans | Filed Under Economics | Comments Off

From Barney Frank on economists [HT: Greg Mankiw]:

Not for the first time, as an elected official, I envy economists. Economists have available to them, in an analytical approach, the counterfactual. Economists can explain that a given decision was the best one that could be made, because they can show what would have happened in the counterfactual situation. They can contrast what happened to what would have happened. No one has ever gotten reelected where the bumper sticker said, “It would have been worse without me.” You probably can get tenure with that. But you can’t win office.

That would be right. I wonder what would have happened had Barney Frank become an economics professor rather than run for Congress.

Clean energy target

by Sam Wylie | Filed Under Economics | 11 Comments

The renewable energy target legislation will soon clear the federal parliament and await royal ascent. I am happy to give my ascent right now — 1.5 thumbs up I would say.   When the legislation comes into effect, wholesale electricity buyers will be required to have renewable energy certificates to cover 20% of their electricity purchases, or else pay $65 for each megawatt hour of electricity without a matching certificate.

I like the expansion in electricity supply that will come with the renewable energy target scheme. Our growing economy will demand more electrical energy over time, but the building of fossil fuel power plants will become more politically untenable in coming years. The renewable energy target should result in about an extra 45,000 GWH per annum of new electricity production over the next 10 years. Read more

A bettor way of forecasting

by Andrew Leigh | Filed Under Economics | Comments Off

My Wryside Economics talk today was on prediction markets. If you’re interested, you can download it from the ABC website.

The recent Frontier Economics proposal to treat emissions differently in electricity has been framed as being about whether price signals flow through to consumers or not. But there were no claims that the Frontier proposal might be favourable in encouraging low emissions generation in electricity. I thought that the CPRS and Frontier’s scheme would be equivalent in that regard.

According to a new paper released today by Stephen Holland there may be a difference. The abstract is over the fold. But the bottom line is this: if generators have significant market power in wholesale electricity markets, then an emissions intensity standard (similar to the Frontier proposal) dominates an emissions tax (equivalent in the  model to a CPRS scheme).

The intuition of these results is relatively straightforward. The weakness of an intensity standard is that it relies more on substitution effects than output effects to reduce emissions. With incomplete regulation or market power, this disadvantage may be helpful since leakage  may offset gains rom reducing output and since market power already inefficiently reduces  output.

The reason is that with market power, output is restricted and carbon prices have less of an impact on it. Now, I didn’t see this in the Frontier report but they are the experts on electricity markets and, in light of this paper, I’d be happy to admit that their scheme may be superior in driving the optimal mix of emissions in electricity if they would provide clear statements and evidence about the existence of significant market power held by electricity generators in Australia. (The issue on price signals remains live, however).

This paper investigates whether an emissions tax (equivalent to an emissions cap) is the  best policy in the presence of incomplete regulation (leakage) or market power by analyzing  an intensity standard regulating emissions per unit of output. With no other market failures, an intensity standard is indeed inferior, although combining it with a consumption tax  eliminates this inferiority. For incomplete regulation, I show that under certain conditions an  intensity standard can dominate any emissions tax (including the optimal emissions tax). This  dominance persists even with the addition of a consumption tax, which ameliorates output distortions and can sometimes help the intensity standard attain the first best (when an emissions  tax/consumption tax combination cannot). Comparing intensity standards to output-based  updating shows that the latter dominates because of its additional flexibility. Finally, I show  that with market power an intensity standard can dominate the optimal emissions tax.

Newspapers need to get a grip

That’s the message from Bill Wyman in this excellent article about why newspapers are failing. The answer is competition but the way he depicts the problems is first-rate. Here is a taste:

And some of it was useful to readers. But let’s be honest. It wasn’t the information the republic needs to govern itself. A very large percentage of it was based, one way or another, on information from press releases, either physical or de facto, from organizations with products to sell.

Press releases contain dated information, the release of which is valuable only to the companies involved; in most cases, they’d actually pay to advertise it, and in that sense it has a negative news value. But vast swaths of a typical American daily is filled with news whose primary source is a press release of one form or another, from entities governmental, political, or corporate. It was part of an unspoken but implicit agreement the papers had with advertisers—that the vast majority of what the paper printed would be complementary with the advertising. (It would be complimentary too, of course.)

The irony is that this all wasn’t as corrupt as it sounds. The primary cause of this wasn’t, paradoxically, to curry favor with advertisers, though they certainly liked it. That was just a lagniappe. The big attraction of a press release? It was safe. No one has ever canceled a newspaper subscription (and no one has ever gotten into trouble internally) because of the publication of material contained in a press release. Anyway, I argue this genetic evolution made timidity the hallmark of most daily American newspapers. It manifested itself in myriad ways.

More Frontier Economics details

In today’s Australian, Danny Price, MD of Frontier Economics, has attempted to clarify what became obscured about their argument on the ETS last week. First, he argues that there has been little acknowledgement by the Government of the economic cost of an ETS. Part of this is a claimed enormous error in the Government’s modeling. But the other part is surely the usual political issue of how policies are sold. In my mind, those economic costs have hardly been hidden and in economics circles they have been all the discussion.

Second, he argues that the shielding in electricity price signals the Frontier report advocates is not about households but about small to medium enterprise. I must admit that I missed this in the Frontier report and didn’t see the reference to the evidence on this. Like the whole notion of gradualism — that has a legitimate basis in economics (unlike so-called ‘churn’ which was not called that in the Australian piece) — what is disappointing is that Frontier provided a theoretical argument but no evidence to push-back on the Government’s more, big bang like approach. Recall, however, that the Government has adopted some shielding too with a carbon tax being favoured for the first year of the CPRS. To me, it seems very important the SMEs see the energy costs they face with carbon prices embedded so that we have a flow-on effect to less energy intensive production. How often are computers replaced? To wait 3-5 years seems silly. But then again, I agree that we need evidence to sort these competing theories out. Where is it?

Finally, the piece talks about a problem with churn (that is, making generator’s pay for permits and making it up at the household end with tax cuts). It was not (again I might have missed it) mentioned in the Frontier report but it has to do with political economy:

The government plans to charge the same carbon price to all generators whether they are high or low emitters. This will make all emitters, good and bad, more expensive and drive up the cost of electricity across the board. But this is one aspect to the scheme the government seems to like. Over the years the government’s coffers will swell from an additional $4 billion a year to $20bn in the sale of permits. This will give it a lot of discretionary expenditure, and the political power that comes with it.

So when it comes down to it, the reason to go with the Frontier scheme rather than the Governments is that we don’t trust the Government to not divert the money in ways that destroy the economy. Again, I’m not sure about that but in the end the Frontier scheme and the Government’s are legislated outcomes. The Government could legislate more commitment — maybe it already has — that prevents this, somewhat speculative, dire consequence. But even if they legislated the Frontier plan, it would be subject to the same political risk.

I agree with the piece that there is lots still to debate on the details of the ETS. What I am not sure about is whether theoretical discussions are contributing to that debate. Evidence is still lacking.
