Economists agree!

Tim Lambert links to this article by Eric Pooley in Slate’s The Big Moneye which points out that, for all the disagreement among economists regarding the details of climate change policy, there is substantial consensus on the following main points
(i) the cost of action to stabilise atmospheric concentrations of CO2 and other greenhouse gases will be of the order of 1 per cent of GDP
(ii) a strong mitigation policy is preferable to business as usual

There is also widespread, though not universal, support for the view that it is best to act early and strongly rather than waiting for more information.

The article makes the point that the quarrelsome nature of economists obscures the level of consensus and that has certainly been my experience.

Also from experience, I know that quite a few readers of this blog are unwilling to believe that (i) can be right. But the argument from personal incredulity is not a sound basis for reasoning. It’s easy to check that the cost can’t be much more than 10 per cent of GDP (about five years worth of economic growth), which contradicts the common intuition that cheap energy is economically vital. Once you accept that upper bound it seems silly to disagree with the experts on the best estimate in the range 0-10.

AARES after-dinner speech

After-dinner speeches are generally best forgotten after the dinner even when (perhaps particularly when!) they are extremely funny. My speech to the Australian Agricultural and Resource Economics Society dinner wasn’t funny at all (at least not intentionally), but a couple of people asked me to write it up for the blog. So I’ve done it. I didn’t have notes when I talked, so this is not an accurate record, more like a reconstruction of what I meant to say

AARES

I’ve been in Cairns for the last few days, at the annual conference of the Australian Agricultural and Resource Economics Society. Although the city hasn’t been much affected by the floods, roads to the south were cut until today, so fruit and vegetables have been in short supply.

The conference opened with an address by Ross Garnaut, who got stuck into the government’s proposals Soldier buy for free permits and exclusions under the proposed ETS. My research group (Risk and Sustainable Management Group) presented a paper on this topic, and a number of others on modelling risk and uncertainty and the complex trade-offs between environmental flows, trees for carbon capture and irrigated agriculture. As well, I presented a paper with Terry Hughes of JCU on the future of the Great Barrier Reef, and gave the after-dinner speech, which I’ve promised to write up and post when I get a free moment. More soon, when I get a free moment or two.

The global spread of the financial crisis

Jim Henley asks a lot of good questions

There’s an awful lot of right/conservative/soft-libertarian economics I consider well and truly refuted by events. That said, I haven’t seen progressive thinkers grappling with the global nature of the current downturn, which seems to be falling on the social democracies and neoliberal regimes and post-mercantile states alike. What does it mean that pretty much all national economies are in a tailspin, regardless of model? Are the safety-net features of the social democracies successfully blunting the impact on their citizens? In ways that can be sustained through another year, say, of recession? Is the protectionism of post-mercantile states in East Asia protecting their industries more than the less protectionist regimes of the neoliberal countries?

I’ll try and answer these, with more confidence on some points than others.

Quick reactions on stimulus package, Mark 2

As expected, the government has announced a new round of fiscal stimulus, and the Reserve Bank has cut interest rates by a further 1 per cent, incidentally achieving a further devaluation of the dollar. All of that is likely to stimulate economic activity, but will it be enough and will it be in the right directions.

The magnitude of the package, $42 billion over 2 years, amounts to around 2 per cent of GDP per year, which is pretty modest given the scale of the crisis. But it follows the $10 billion package from late last years, and is virtually certain to be followed by more. I’d be surprised if the deficit is held under 5 per cent of GDP for 2009-10, and deficits are likely to continue for quite a few years. With fiscal stimulus of that magnitude and interest rates near zero, it ought to be possible to keep the inevitable recession to a relatively modest scale, assuming (a big one) that the international financial system is on the road to stabilisation.

The main concern I have with the package is that it continues a heavy focus on construction. That sector has been the first (apart from the finance sector itself) to take a big hit, but it won’t be the last. It’s great building schools, but we need to be hiring teachers, teachers aides and support staff to work in them. As I’ve mentioned before, human services are the most labor-intensive areas of the economy, and also an area that’s been constrained in the era of economic liberalism that is now coming to an end. Hopefully, we’ll see more action on this front, and on direct measures to help the unemployed in the Mark 3 package.

I also have some concerns about the idea of insulating homes. That’s great if it’s additional to the impact of the emissions trading scheme, but not so great if all it does is make it easier for electricity companies to meet their targets.

Easter in January

As many readers will have noticed, the supermarkets began selling Easter items like eggs and hot cross buns early in January, just as they were clearing out the remaining Christmas stock. I must say this is a sorry commentary on what is supposed to be a consumer society

* First off, what about those of us who want to celebrate Christmas and Easter at the same time? If the stores could get their act together and put on the Easter items a couple of weeks earlier this would be easy, but they seem to stick to the tradition of one festival at a time

* Valentines Day is only a couple of weeks away, but there’s scarcely anything in the way of Valentine’s items. Given that Valentines falls in the middle of the Easter season surely it’s not beyond the capacity of the marketing guys to come up with Valentine-themed Easter eggs, or Heart-Cross buns

* There’s no risk of going short on gluttony during Lent, but there’s a long drought from Easter to Halloween, with only Mother’s Day and Father’s Day to provide options for excess consumption. Surely they could invent an Australian version of Thanksgiving and put it in midwinter.

Refuted economic doctrines #5: Trickle down

The idea that policies favorable to the wealthy, such as financial deregulation and favorable tax treatment of capital income, will ultimately benefit everybody has been described, pejoratively, as ‘trickle down’ economics.

The same idea been summed up, more positively, in the aphorism ‘a rising tide lifts all boats’ attributed to John F Kennedy, and a favorite of  Clinton advisers such as Gene Sperling and Robert Rubin. (It should be noted that this phrase is also used in the context of debates over free trade and over the effects of macroeconomic expansion. While it generally implies that we should focus on expanding aggregate income without too much concern over distribution, it is less sharply focused than the ‘trickle down’  pejorative.

Whatever you call it, trickle down economics is one of the casualties of the financial crisis. I’m not the first to point this out, and I’m sure I won’t be the last, but here’s a piece summing up my thoughts.
