Economics Colloquium, Thursday at 4:30 p.m.

Hillary Caruthers, a visiting professor at Berry College, will visit campus Thursday and deliver the next edition of the Economics Colloquium.  Professor Caruthers is a recent Ph.D. from the University of Wisconsin-Madison.   Her talk will be at 4:30 Thursday in Steitz 102.

“Household Risk Management and Rural to Urban Migration in Indonesia”

Hillary Caruthers
Berry College

ABSTRACT:  This paper investigates the role of risk in rural to urban migration decisions using Indonesian household-level panel data. Specifically, I use consumption data and measures of household risk aversion to test whether rural to urban migration is a means of managing risk among uninsured households via the diversification of household income flows. Most previous studies of risk and migration do not analyze the migrant’s choice of destination but instead focus on the relationship between risk aversion and the likelihood of migration; however, if migration is motivated, in part, by household risk management, then the level of risk aversion should impact both the propensity to migrate and the destination of migration. In this paper I generate predictions regarding the relationship between household risk aversion and the economic riskiness of receiving regions and test these predictions using a multinomial logit estimation. Empirical results generally affirm the predictions of the model. Households prefer to send migrants to destinations with lower consumption variability and, as predicted, this preference is stronger among households with higher risk aversion. Also, all households prefer destinations where average consumption is less correlated with home consumption.

Special EconTea: The Nuclear Option

There will be a special Econ Tea on Tuesday, May 20 at 2:30 p.m. in Briggs 217 to discuss this paper:

Joseph Michael Newhard, “The Stock Market Speaks: How Dr. Alchian Learned to Build the Bomb,” Forthcoming in Journal of Corporate Finance.

The paper covers the remarkable story of Armen Alchian’s attempt to figure out the fissile material in nuclear weapons.  Here’s Alchian’s telling of the story:

We knew they were developing this H-bomb, but we wanted to know, what’s in it?  What’s the fissile material? Well there’s thorium, thallium, beryllium, and something else, and we asked Herman Kahn and he said, ‘Can’t tell you’… I said, ‘I’ll find out’, so I went down to the RAND library and had them get for me the US Government’s Dept. of Commerce Yearbook which has items on every industry by product, so I went through and looked up thorium, who makes it, looked up beryllium, who makes it, looked them all up, took me about 10 minutes to do it, and got them. There were about five companies, five of these things, and then I called Dean Witter… they had the names of the companies also making these things, ‘Look up for me the price of these companies… and here were these four or five stocks going like this, and then about, I think it was September, this was now around October, one of them started to go like that, from $2 to around $10, the rest were going like this, so I thought ‘Well, that’s interesting’… I wrote it up and distributed it around the social science group the next day. I got a phone call from the head of RAND calling me in, nice guy, knew him well, he said ‘Armen, we’ve got to suppress this’… I said ‘Yes, sir’, and I took it and put it away, and that was the  first event study. Anyway, it made my reputation among a lot of the engineers at RAND.

LU Alum and Serial Entrepreneur Featured

’97 Lawrence alum Abir Sen is featured in a recent article in Twin Cities Business. Sen recently joined Lawrence’s Board of Trustees and has been an active participant in our Innovation and Entrepreneurship program as both guest expert and member of the advisory committee. See below for his view of the right job for him.

Tyler Vigen has opened up the world of spurious correlations like no other with his aptly titled website, Spurious Correlation.  Whether it’s the remarkably tight relationship between US spending on science, space and technology with suicides by hanging, strangulation and suffocation or a more loosely related relationship between Stanley Cup goals and Suicide by Pesticide (I made that one up myself!), Vigen is Johnny-on-the-Spot with fitting data for no greater purpose than amusement.

A Great Leap Forward, Thursday at 4:30

Alexander J. Field from Santa Clara University will be on campus Thursday to deliver a public lecture based on his book, A Great Leap Forward: 1930s Depression and U.S. Economic Growth  (Amazon link here).

Professor Field argues that despite the bottoming out of aggregate demand, total factor productivity growth increased faster during the Great Depression than any other decade in U.S.  history.   My read of the book makes the assertion almost uncontroversial, yet the notion of rapid productivity growth disrupts conventional views on the role of World War II in terms of “getting the US out of the depression,” and also in terms of setting the stage for the post-WWII economic boom.  Field makes this case quantitatively, walks through some of the implications, and puts it in historical context, including his thoughts on some recent events.  This is very high quality economics and should play very well with economics students and a general audience.

You can read a brief interview with Field on his work in the New York Times.

The talk is Thursday, May 15 at 4:30 p.m. in Wriston Auditorium.

This is the Phi Beta Kappa lecture as part of the Visiting Scholars Series.  We are fortunate that the Senior Experience is providing funding to bring Professor Field to campus. 

For Whom Does the IPCC ‘Tol’?

I probably have more thoughts on this than I will convey here, but I have seen a number of unusual items related to the economics of climate change.  First, a few weeks ago I saw that University of Sussex economist Richard Tol had begged off the Intergovernmental Panel on Climate Change because he disagreed with how the recent IPCC technical report was translated into “journalist speak” in the Summary for Policy Makers (SPM).  The SPM takes several thousand pages of technical reports and boils them down to an Executive Summary in the 25-50 page range.

From The Guardian we have this: “Richard Tol told Reuters he disagreed with some findings of the summary to be issued in Japan on 31 March,” and the story follows up with some choice quotes from Professor Tol:

The drafts became too alarmist…. It is pretty damn obvious that there are positive impacts of climate change, even though we are not always allowed to talk about them…. They will adapt. Farmers are not stupid.

Okay, here is a rebuttal from an IPCC co-author.

Of the 19 studies he surveyed only one shows net positive benefits from warming. And it’s the one he wrote,” said Bob Ward, policy and communications director of the Grantham Research Unit on Climate Change and the Environment at the London School of Economics.

More on Tol later.

Meanwhile, Harvard’s Robert Stavins — a giant in environmental economics, really — has come out and publicly harangued the IPCC over its SPM saying “the resulting document should probably be called the Summary by Policymakers, rather than the Summary for Policymakers” (his emphasis).   Professor Stavins is specifically addressing the part of the report that he helped coordinate, and is very clear that it is the SPM, not the chapter it is based on, that he takes issue with.

As someone in teaching environmental economics year in, year out, I can say I am a more than a little distressed that some top-flight economists are worrying about the politicization of the IPCC SPM.

Now back to Professor Tol, who is author of a very influential piece in the 2009 Journal of Economic Perspectives, “The Economic Effects of Climate Change,” that evidently contained some errors.  Here’s Tol in “”Correction and Update: The Economic Effects of Climate Change” from the most recent JEP:

Gremlins intervened in the preparation of my paper “The Economic Effects of Climate Change” published in the Spring 2009 issue of this journal. In Table 1 of that paper, titled “Estimates of the Welfare Impact of Climate Change,” minus signs were dropped from the two impact estimates…

Gremlins, wow.  I guess that’s putting a good face on publishing erroneous data in the profession’s flagship journal.   Here’s the updated figure:

Tol Climate Change

 

The Figure is from the JEP article (click for a bigger image); the “hipster economist” reference is here.

The kerfuffle over the figure is that the little dots represent the central estimates, and most of the estimates show negative impacts on GDP.  The glaring exception is Tol’s own estimate of a 2.3% increase at 1 degree (C) of warming, which likely accounts for the shape of the fitted curve (the other study he reports with 1C warming estimates  a loss of -0.4% of GDP).  As the quote critical of Tol says that “of the 19 studies he surveyed only one shows net positive benefits from warming. And it’s the one he wrote.”  That appears to be approximately accurate, though there is one other study that estimates zero to 0.1% increase at 2.5 degrees warming.  

The larger issue is probably that the economic impacts simply aren’t as big as one would think.  Of the 20 studies Tol cites, about half look at 2.5C of warming, and the average impact on world GDP among these studies is about a 1% of world GDP.

Unfortunately, most studies haven’t gone out very far past that, and I would guess that most people who have looked at carbon emissions and projected temperature increases believe the impacts will exceed 2.5C, and no matter who you ask, damages appear to be increasing at an increasing rate at that point.

The link to the article is above, and all the data from the article are available here.  Tol has a more complete essay on his views in the Financial Times.

Cadillac Desert, Wednesday and Thursday in Briggs 223

I will be showing the PBS Series, Cadillac Desert: The American West and its Disappearing Water, Wednesday and Thursday night in Briggs 223.  The episodes will go off on the hour each night.  Episode summaries are here.

The documentary series is based on Marc Reisner’s epic novel about western water development, and particularly the role of the Bureau of Reclamation and the Army Corps of Engineers in shaping that destiny (NYT review here).  The first episode is about the delivery of water to Los Angeles and how that shaped the development of that urban area.  The second focuses specifically on the Colorado River and how that is divvied up.  The third episode looks at agricultural development in California’s Central Valley.

Econ Tea Monday — Pre-Registration Advising and Major Consultation… and, Look, the Pie!

We will host an Economics Tea on Monday, April 21 at 4:30 in Briggs 217 to convene for lively discussion and delicious pie.  Faculty will be available to discuss pre-registration and give advice to anyone interested in learning more about the department major.  We will once again be offering various types of pie.

For the Google-impaired amongst you, here is a link to the major and minor requirements.

Key things for potential majors to know:

The core series sequence is Micro Theory (ECON 300), Econometrics (ECON 380), and Macro Theory (ECON 320).  These are generally offered once per year, with ECON 300 in the fall, ECON 380 in the winter, and ECON 320 in the spring.  We believe that taking these back-to-back-to-back is a good strategy.

You need calculus (MATH 140 OR MATH 120 & MATH 130) in order to take Econ 300.

You need calculus in order to take Introduction to Probability and Statistics (MATH 207).  Math 207 is only offered in the fall term each year.

You need MATH 207 and either ECON 300 or ECON 320 in order to take Econometrics (ECON 380).  We recommend that you take MATH 207 in the fall and ECON 380 in the winter.

The full schedule is right here.

Life is Priceless: Only if You are an Incurrable Romantic

In this New York Times blog posting, Uwe Reinhardt, one of the most eloquent economists I have ever heard speak, tweaks Congress for its ignorance of the notion of opportunity cost and for a lack of understanding of the fundamental principles of policy making.  Furthermore, he provides a link to a marvelous discussion between Milton Friedman and a University of Chicago student that took place as part of the Free to Choose series in the 1970s.

Remarkably, this is the 1000th post on the Lawrence Economics Blog.  Wow.

Along the way, we have demonstrated that economists are in surprising agreement about a surprising number of things, though we tend to differ from Lawrence students.   We have had some actual economic analysis, such as explaining Giffen Goods to Matthew Yglesias, evaluating the argument that a great wine shortage is upon us, and reviewing Malcolm Gladwell’s Outliers.

We’ve also looked at topics such as consumption smoothing (for goods such as underwear) without and with a random stopping point (such as a robot uprising).

I’d probably be remiss if I didn’t mention something about innovation, such as our (okay, mycontinuing fascination with Joseph Schumpeter, as well as these remarkable spitballing roots of an American icon.

He’s a doctor, he’s a college professor, but he’s also a sort of rough and tumble guy.

Spanning the globe, we have taken on the literal meaning of place names, challenged the conventional wisdom on why people (such as Jonathan) vote the way they do, and normalized the data for Olympic medal counts so that Hungary might fare a little better

Speaking of Hungary and the eastern block, Professor Galambos’ has posted some great stuff on Goulash Capitalism and his (should-be) annual Lenin’s birthday message. 

No doubt our most intriguing posts are our continuing series on moral (and other) hazards. Here’s a taste:

L.W. Burdeshaw, an insurance agent in Chipley, told the St. Petersburg Times in 1982 that his list of policyholders included the following: a man who sawed off his left hand at work, a man who shot off his foot while protecting chickens, a man who lost his hand while trying to shoot a hawk, a man who somehow lost two limbs in an accident involving a rifle and a tractor, and a man who bought a policy and then, less than 12 hours later, shot off his foot while aiming at a squirrel.

“There was another man who took out insurance with 28 or 38 companies,” said Murray Armstrong, an insurance official for Liberty National. “He was a farmer and ordinarily drove around the farm in his stick shift pickup. This day – the day of the accident – he drove his wife’s automatic transmission car and he lost his left foot. If he’d been driving his pickup, he’d have had to use that foot for the clutch. He also had a tourniquet in his pocket. We asked why he had it and he said, ‘Snakes. In case of snake bite.’ He’d taken out so much insurance he was paying premiums that cost more than his income. He wasn’t poor, either. Middle class. He collected more than $1-million from all the companies. It was hard to make a jury believe a man would shoot off his foot.”

Who knew people were so crazy, er, rational? Anyway, Incentives matter! 

LU Environmental Studies in the NYT

There is a recent NYT piece on the proposed iron mine project up on the Bad River in northern Wisconsin, and it is a big mine indeed:

The $1.5 billion mine would initially be close to four miles long, up to a half-mile wide and nearly 1,000 feet deep, but it could be extended as long as 21 miles. In its footprint lie the headwaters of the Bad River, which flows into Lake Superior, the largest freshwater lake in the world and by far the cleanest of the Great Lakes. Six miles downstream from the site is the reservation of the Bad River Band of Lake Superior Chippewa, whose livelihood is threatened by the mine.

The piece cites our own geologist, Marcia Bjorenrud, who evidently investigated the possibility of acid drainage from the project:

Before the passage of the bill, Marcia Bjornerud, a geology professor at Lawrence University in Appleton, Wis., testified before the legislature that samples she had taken from the mine site revealed the presence of sulfides both in the target iron formation and in the overlying rock that would have to be removed to get to the iron-bearing rocks. (When exposed to air and water, sulfides oxidize and turn water acidic, which can be devastating to rivers and streams, along with their fish populations.) Sulfide minerals, Professor Bjornerud said, would be an unavoidable byproduct of the iron mining. But the bill does not mandate a process for preventing the harm from the sulfide minerals that mining would unleash.

Acid drainage is a particularly nasty problem associated with many mining projects, so these issues tend to be at the fore of any mine permitting process.  When sulfides are exposed to water and air, they oxidize and become acidic.  The overhead shots from problem mines  often look like someone dumped battery acid into a sink (see here from this photo essay of a particularly egregious case).

Thnx to “Mr. E” for the pointer.

Getting a Ph.D. in Economics

Over the next few weeks, we will be compiling some resources for those of you who are interested in doing graduate work in economics.  Certainly, your first stop should be to talk with one or more of your professors (especially the economics professors, I suppose).   The American Economic Association is probably your next stop.

You might also check out the Miles Kimball / Noah Smith essay on the economics Ph.D.

I have this on my mind because I just received Stuart Hillmon’s Getting a Ph.D. in Economics in the mail.   If you care to take a look at the book, you can come by and I’ll loan it to you.

S-Curves and the Death (?) of the Microwave

If you’ve ever wondered what an “S-Curve” is in the context of the diffusion of innovations, check out the piece at  Quartz on “The Slow Death of the Microwave.”  The piece shows what are effectively household adoption rates of various consumer items over the past 100+ years.  It is called an “S” curve because the initial roll out tends to be somewhat prolonged (the bottom _ of the S) followed by a rather steep increase as the item catches on (the / part), and finally a leveling off when most of the population has adopted it.  The curves themselves contrast both rates of diffusion and total penetration rates.  The microwave, for example, went from 10 to 80% of households in a ten-year period.  Compare that with stoves, washers, dryers, and even telephones, which took their sweet time becoming the proverbial “household” items.

S Curves

The figure* actually says a lot about the characteristics of American households.  At the onset of World War II, for instance, the majority of households did not have refrigerators, clothes washers, telephones, or color televisions.  The curves also show the dramatic impact of the Great Depression on the diffusion of telephones, electricity (both stunting then accelerating diffusion), and automobiles.  

As for the article, it’s a fascinating look at the microwave, though it seems a bit premature to be calling its “death,” given that the vast majority of households can still pop corn and defrost meat in short order. Bloomberg seems to agree with me on this point.

But when you read a little deeper, it turns out that people aren’t actually abandoning microwaves; they’re just not replacing them as frequently.

Yep.  Still some cool graphics, though.

 

*The graphic is taken from the Quartz article, which was taken from an old New York Times article.

Spring Forward!

Here are some courses, updates, etc… germane to the Spring term on Briggs 2nd:

(NEW) ECON 495: Mathematics for Economists   ARRANGED  Professor Rhodes.   This course is a 400-level course emphasizing some of the fundamental mathematical theory and practice common in the economics profession.   We are in the process of coordinating times and places, so please contact Professor Rhodes or Gerard ASAP is you are interested.

ECON 495: Individual and Community  TR 12:30-2:20 in the Econ Seminar Room, Professor Wulf.

Professor Steve Wulf (!) is cross-listing his fabulous course for the economics department for the first time. That being the case, here is the course description:  This course studies a variety of theoretical responses to the emergence of open societies in the West. Topics include the competing demands of individuality and community in religious, commercial, and political life.   The course promises a very healthy dose of history of economic thought.

ECON 460:  International Trade   MWF 8:30-9:40 in the Econ Seminar Room, Professor Devkota.

ECON 405:  Innovation and Entrepreneurship  9:50-11:00 MWF in the Econ Seminar Room, Professor Galambos.

For those of you looking for some theoretical foundations to thinking about innovation & entrepreneurship, look no farther.  An excellent complement to IO and Theory of the Firm.

ECON 320:  Intermediate Macroeconomics MTWR Briggs 223.

Always a highlight!

CANCELLED ECON 295:  Labor Economics 3:10-4:20 MWF in the Econ Seminar Room, Professor Rhodes

ECON 200: Development Economics 11:10-12:20 MWF in the Econ Seminar Room, Professor Devkota 

This is also a good bet for next term, especially for those interested in understanding economic growth across countries.

ECON 225:  Decision Theory  MWF 1:50-3:00 Briggs 223, Professor Galambos

This class is not full, but enrollment is heavy (30+).  We have committed to offering this in 2014-15 and expect it will be offered in 2015-16.

ECON 280:  Environmental Economics TR 12:30-2:20, Briggs 223, Professor Gerard

This class is full and the current wait list is at about 8 or 9.  It is offered each year, including Spring 2015.

ECON 120:  Introduction to Macroeconomics  MWF 12:30-1:40, Briggs 223, Professor Rhodes

The longest journey begins with the first step… and then the second step.  This could go either way, as ECON 100 is not a prerequisite.
