I have just started reading Geoffrey Miller’s Spent. It opens with a mildly amusing faux discussion in which a modern person seeks to convince some Cro-Magnons of the benefits of the modern way of life. The modern person is…

Coyle on happiness

Over the weekend I read Diane Coyle’s The Economics of Enough. I particularly enjoyed her dismantling of the concept that to increase happiness we should forget about growth. My reading list on…

Dangerous ideas

Recently, I was asked whether the idea…

The benefit to being right

In all the debates about human biases, I like to believe that there is some benefit to being right. There must be some evolutionary benefit to knowing the true state of the world (on average). That is not to say that the benefits will always outweigh the costs, as the aim is to reproduce.…

Veblen’s The Theory of the Leisure Class, Part III

Thorstein Veblen has been ranked seventh in a poll of economists on their favourite, dead, 20th century economist. He ranked behind Keynes, Friedman, Samuelson, Hayek, Schumpeter and Galbraith. His supporters were…

Hungry judges

The media and blogosphere has dedicated plenty of column and blog inches to a recently published study by Danziger and colleagues on how parole rates by Israeli…

The Simon-Ehrlich bet

I’m back on the population bandwagon today, and I wanted to…

Evolutionary psychology and the left

Belief in evolution is often considered the domain of “the left”. Apart from being true, evolutionary theory provides a ground for opposition to creationists. It is often…

Ultimate population limits

Given the recent discussion on population that the release of Bryan Caplan’s Selfish Reason to Have Kids has triggered (my posts here, here and here), I have been contemplating some physical limits of what the ultimate human population could be. The current global population is around 6.8 billion and is growing at…

Happiness adjusts

Robert Frank has written a piece for the New York Times on why worrying is good. He writes of the well-known phenomena that after large life changes, people’s level of happiness tends to drift back to…

Veblen’s The Theory of the Leisure Class, Part II

Following last week’s post on Thorstein Veblen’s The Theory of the Leisure Class, I’ve progressed through some more of the book (to chapter 9). It hasn’t got any easier to read, but…

Heritability of religion and fertility

The United States is one of the few developed countries in the world with a fertility rate close to the replacement rate - that is, the rate of fertility required to…

Population and the tragedy of the commons

Like all economists, I am familiar with the concept of the tragedy of the commons. However, possibly like most economists, I had not read Garrett Hardin’s 1968 article from where we derive the phrase - that is, until yesterday. As a result, I did not understand the extent to which overpopulation concerns underpinned Hardin’s writing (HT…

Veblen’s The Theory of the Leisure Class

I have started reading Thorstein Veblen’s The Theory of the Leisure Class. The book was published in 1899 and…

Trust and education

Razib Khan of Gene Expression has put together a series of charts on changes in trust in the United States over the last 40 years. The trust data comes from the Genera…

Bryan Caplan’s Selfish Reasons to Have More Kids

Bryan Caplan has a simple recommendation. Have more kids. If you have one, have another. If you have two, consider three or four. As Caplan spells out in his book, Selfish Reasons to…

Libertarians and fertility

As I noted in yesterday’s post, Bryan Caplan has written the lead essay for this month’s Cato Unbound on The Politics of Family Size. Caplan argues that as there are strong benefits to increasing population, libertarians should support “libertarian policies” to increase population, educate and persuade…

Would Julian Simon worry?

This month’s Cato Unbound is on The Politics of Family Size. The lead essay is by Bryan Caplan, who is on a mission to get people to have more kids.

Fogel and supersized humans

Last week, the New York Times ran a profile of economist Robert Fogel in anticipation of the release of the book The Changing Body: Health…

Rotten kids and altruism

Gary Becker’s 1976 article Altruism, Egoism and Genetic Fitness: Economics and Sociobiology is an article that I cite often. Becker’s closing paragraph has one of the…

Morris’s Why the West Rules For Now - Part II

Following yesterday’s post on Ian Morris’s approach to biology in Why the West Rules - for Now, below are my thoughts on the some other elements of the book.

Morris’s Why the West Rules For Now

Over the Easter break, I read Ian Morris’s Why the West Rules- for Now. Morris seeks to develop what might be called a “unified theory of history” that can shed light on why…

Genetically testing similarity

In my last post, I questioned whether…

In the company of a stranger

I have just left the Social Decision Making: Bridging Economics and Biology conference, with one of the last speakers being Paul Seabright, author of The Company of Strangers. I will post some thoughts on Seabright’s presentation (and some of the other presentations at the conference) after Easter and once I have read the related…

Consumption and fitness

After posting Friday’s piece on Hansson and Stuart’s paper on natural selection and savings, I realised I had not commented on one of the most important assumptions made by the authors. To get their…

Social Decision Making: Bridging Economics and Biology

I am at the Social Decision Making: Bridging Economics and Biology conference (the abstracts of which can be downloaded here). As the name suggests, the basic idea behind the conference is to pull together economists and evolutionary biologists to develop new collaborations and examine how their…

Jones on IQ and immigration

David Henderson has posted on a recent presentation by Garett Jones of George Mason University in which Jones discussed IQ and cooperation.

What can evolutionary biology offer economics?

This is my last post on David Sloan Wilson’s series Economics and Evolution as Different Paradigms (my earlier three posts are here, here and here). While much of Wilson’s attack on economics is against a caricature of the discipline, he ties up his series with a few…

Lehrer on measurement

Jonah Lehrer has expanded his recent focus on measurement and grit (on which I recently posted) in an article on the usefulness of the…

Evolution and the invisible hand

In David Sloan Wilson’s blog series Economics and Evolution as Different Paradigms (which I have recently posted about here and here), Wilson discusses the…

Wilson on economics and evolution

As indicated in my last post, between December 2009 and October 2010, evolutionary biologist David Sloan Wilson wrote a series of posts titled Economics…

The Evolution Institute

In the first of a series of blog…

Measurement nihilism

Following from my recent post on Scott Barry Kaufman’s heritability measurement nihilism, Jonah Lehrer has gone a step further and taken a swipe at measurement in general, and in particular, at short-term tests.…

The heritability debate, again

Like the level of selection debate, the debate about what heritability means has a life of its own. The latest shot comes from Scott Barry Kaufman who…

Micromotives and macrobehavior

In a post a couple of months or ago as part of a debate on complexity in aid, I recommended Thomas Schelling’s Micromotives and Macrobehavior as a good starting point for understanding complexity science. The book predates a lot of the language associated with complexity science (in fact, I don’t think it uses…

Income and IQ

As I noted in my recent post on Malcolm Gladwell’s Outliers…

Evolution and irrationality

In a classic behavioural economics story, research participants are offered the choice between one bottle of wine a month from now and two bottles of wine one month and one…

Economists and biology

Mike the Mad Biologist has posted this piece on economists’ understanding of biology. He pulls apart some statements by Russ Roberts and suggests that if economists are going to use biology as a model for the…

Gladwell’s Outliers

After flipping through Malcolm Gladwell’s Outliers: The Story of Success l…

Diamond on biological differences

On Friday afternoon, as has happened a few times, I was asked if I had read Jared Diamond’s Guns, Germs and Steel. How could an…

Unskilled and unaware

Robin Hanson has had another stab at the oft-quoted paper by Kruger and Dunning, Unskilled and Unaware of It. The first couple of sentences of the paper’s…

Crisis in human genetics?

It is a bit over a year since Geoffrey Miller wrote this piece foreshadowing a crisis in conscience by human geneticists that would become public knowledge in 2010. The crisis had two parts: that new findings in genetics would reveal…

Genetic distance and economic development

The History and Geography of Human Genes has heavily influenced the way I think about human evolution. Even though it is getting old at a time when masses of population genetic data are being…

Trade and natural selection

Economic theory tells us that trade makes the parties involved better off. Through trade, a person can specialise in the activity in which they have a comparative advantage. A person is better off even if they are trading with someone who is better than them at all activities. This is because the less productive person will still have a…

Janet Browne’s Charles Darwin: Voyaging

Having put it in the top ten books I had read in 2010 despite being only halfway through it then, I feel somewhat obliged to offer a review of Janet Browne’s Charle…

Kling on patterns of sustainable specialisation and trade

I have just listened to the recent Econtalk podcast with Arnold Kling on his new “paradigm”, Patterns of Sustainable Specialisation and Trade (PSST). On first thoughts, I am not convinced about the idea. If anything, the paradigm appears to…

Crime and selection of aggressive males

As I posted a couple of months ago, a higher level of violence in a society may lead women to prefer more…

Banking as an ecosystem

Most of my interest in the use of biology in economics concerns humans being subject to the forces of…

Evolutionary economics and group selection

As my research intersects economics and evolution, I have found it inconvenient that the term “evolutionary economics” is already taken. Evolutionary economics is an area of economics inspired by biological processes, with interactions between firms, industries and institutions examined using evolutionary methods. The economics is…

What is the objective?

An economist typically bases their economic models on an assumption that the economy is composed of agents who gain utility from consumption. From the…

Why do rich parents bother?

Is aid really so complex?

Since Bill Easterly stuck his head above the parapet last week and referred to complex systems in response to Paul Collier, the “complexity” community has been up in…

DeLong on the pace of evolution

Any theory that seeks…

The speed of cities - afterthoughts

Having recently discussed cross-country variation in time preference and the pace of life, I have found it interesting reconciling the conclusions.

The speed of cities, part II

As I described in my last post, there is a strong relationship between the size of cities and the residents’ speed of walking. The larger the city, the quicker its residents…

The speed of cities

Over the weekend, I listened to a great Radiolab podcast in which Bob Levine was interviewed about the pace of walking in cities. Bob spoke about how people tend to walk faster in larger cities, with this relationship surprisingly consistent. Where…

Clark on violence

In Greg Clark’s excellent book A Farewell to Alms, Clark posited that there was only one important event in human history - the Industrial Revolution. Before that time, per capita income…

More on violence

Following yesterday’s post on female preference for masculine men, a couple of old articles came to mind.

Selection for aggression

Masculine appearance in a man is an indicator of their health, which in turn leads to more viable offspring. On this basis, one might assume that women prefer masculine men.…

My top 10 books in 2010

Trading fish

Alex Tabarrok has posted on Marginal Revolution a piece on the expansion of “catch shares” as a fisheries management tool. Under catch shares (also called individual tradeable quotas or ITQs), each fisher owns a…

A wasteful Christmas

As noted by Chris Berg, the Australia Institute has rolled out its annual reminder of Joel Waldfogel’s almost 20-year old observation about the wastefulness of Christmas giving. As the gift giver has less than complete knowledge of the preferences of the recipient, the recipient tends to value the gift at…

Fitness spreading

One of the issues at the core of my research is the speed of human evolution, particularly over the last 10,000 years. There are several potential arguments to suggest that…

The evolution of technology

In Kevin Kelly’s recent appearance on Econtalk, he talked about his new book What Technology Wants. I have not read…

Post-crisis economics

Over the weekend I listened to the three-part Lionel Robbins Memorial Lectures 2010, this year given by Lord Adair Turner.

Coal and the industrial revolution

In a recent discussion as part of the Cato Unbound series, Matt Ridley suggested that we shouldn’t forget the Materialist explanation for the industrial revolution. The difference between the British and other bursts of economic activity, such…

Better school performance leads to more children

An article by Anna Goodman and Ilona Koupil in last month’s Evolution and Human Behavior found a link between school performance and number of children and grandchildren (in Sweden 1915-1929). This effect, as might be expected, held in males only. The number of…

Procrastination

Procrastination bothers me. Not in the sense that I want to procrastinate, but biologically. Why would a tendency to procrastinate evolve?

The value of a species

Today I listened to an old (2006) interview with E.O Wilson by Michael Novacek (thanks NYAS). Wilson had a few criticisms of economics - the heavy basis in mathematics for one - and he stated that this had…

There is but one social science

“There is only one social science and we are its practitioners” - George Stigler, economist

The short wingman - do humans use visual illusions to attract a mate?

An ABC news article last week reported a study by Professor John Endler on the use of visual tricks by male bower birds to make themselves look larger to females. By placing small objects at the front and larger objects…

Economics versus history - is this the right debate?

Over the past few days, Tim Harford has been engaging in a debate with Gideon Rachman (along with a few other bloggers)…

Education in the developing world

Following from my recent blog on over-education, Tyler Cowen’s words on under-education for most of the world should be noted.

Sports stars born early in the year

One of the more interesting pieces of evidence in the nature or nurture debate is the that athletes…

Should we tax education?

Over the last few weeks, Bryan Caplan of Econlog has engaged in a debate with his former teacher Bill Dickens over the social value of education. Brian’s position is that education is largely used for signalling rather…

Patience and IQ

Following from my recent post on marshmallows and impatience, I have come across the following article by Dohmen et al. It was found…

The predictive power of marshmallows

I have gone through the back catalogue of podcasts for WNYC’s Radiolab for a couple of months now. I got into it after ABC radio substituted it for the Science Show for two weeks in late June. It is sensational – great content and…

It’s a risky business attracting a mate

Last week, ABC’s Catalyst had a story on skateboarders taking extra risks based on the presence of an attractive researcher. This was based on article published earlier in the year (Ronay, R.…
