We were recently required to give 15 minute presentations, so I mashed up three topics. The first is the things about my thesis that I am most worried about, the second is my other two papers (after the paper presenting the model) and the third is some thought bubbles I had recently about the budget constraint. Fears and the 2nd and 3rd papers ended up getting mashed together because I thought that would be the easiest way to discuss these issues.
My first paper is going to be purely theoretical. I’m going
to try and pull together the literature from economics, psychology and
philosophy to produce a preliminary model of happiness.
One of the main motivations for this is that happiness
studies have been very empirically driven since inception and this is now
reaching the point where there is some confusion in the inferences we draw from
our measurements. It would be beneficial, I think, not least of all for our
scientific practice, to develop a clear, mechanistic theory that agrees with
our intuitions. We can then discuss our empirical findings in the context of
this model.
A related major motivation for this paper is that I worry that
our admirable dedication to measurement means that we are overlooking important
elements of happiness that can’t be measured. This wasn’t a problem in the
early days of hedonic psychology and the like but recently I get the feeling
that we know so much about some things that we’re growing increasingly
comfortable acting as though that’s all there is. I am talking here especially
about the differences between subjective wellbeing, which is mostly an
affective concept, and psychological wellbeing, which is a much more
intractable existential concept.
So I’m mostly doing theory and mostly interested in theories
that can’t be measured. This brings me to my first big worry with my paper,
which is that I won’t have very good empirical evidence to back up what I’m
saying.
This doesn’t mean that I don’t intend to do anything
empirical. Rather, it means that I am going to go looking for suggestive
empirical evidence rather than gold standard identification.
Here are the two thought bubbles that I have at the moment:
First, I want to emphasise the importance of preference.
Most happiness research has estimated across huge samples and taken the
average. We are left with stylised facts like: married people are happier. But
then Bruce has a paper where he shows that married people who are in
dissatisfied marriages are actually made less happy by their marriages than
unmarried people.
The issue here seems to be one of preferences.
On the flip side, we get some research into the impact of
certain preferences. Tim Kasser, who I intend to write a paper critiquing, has
produced several studies showing weak negative impacts from materialist
preferences on happiness. Unfortunately, not one of his papers controls for
whether the participants are successful materialists or not.
I’m currently poking around on this stuff in HILDA and I
think success as a materialist is important. Transitional effects of income
growth are more powerful and sustained for materialist than for
non-materialists, and rich materialists are happier than rich non-materialists.
I also have a data set of all Dutch millionaires and they seem to be an
exceptionally happy bunch.
This leads me to the second paper that I want to write for
my thesis. I want to use big data sets to put some people into groups based on
strong preferences for things that are easier to observe, like materialism,
then use these grouping to see whether preferences satisfaction is important to
happiness or just doing the things that should make people happy on average.
This would allow us to determine whether the source of
happiness really is subjective, or whether there are actually some things that
will just work for everyone.
For this work I am hoping to be able to combine the 3 big,
high quality longitudinal panels from Australia, Britain and Germany.
The hardest part will be sorting people into groups based on
preferences because preferences are hard to observe. HILDA has some questions like ‘how important
is financial security to you’ which can be used to proxy for preferences, but
these are often worded poorly. For example, financial security is not the same
as materialism.
More importantly, you really want this preference sorting to
be done in terms of what people are willing to trade off, which the HILDA
variables don’t capture. There is little reason in the HILDA questions for
people not to answer 8+ for community, family, financial security and leisure
even though maximising all of these preferences simultaneously is likely to
prove extremely difficult.
I have a lead on how to surmount these issues in a paper by
Manski called ‘Identification of income-leisure preferences and evaluation of
income tax policy’. This explains a method for reading trade-off preferences
out of longitudinal data. Hopefully it will lead to a wider literature; I
haven’t looked into it much yet.
Moving to the third paper: one of the most important
findings in this literature in recent years is the consistent relationship
between log-form income against happiness. I want to see whether this
functional form holds for other variables that I have in my agency cluster like
health and political rights, and also for other determinants of happiness like
family, leisure, religion and community participation.
Perhaps most importantly, I want to see whether some factors
do not exhibit diminishing returns. In particular, I am curious to see whether
aspects of psychological wellbeing or meaning
do not exhibit such a truncating relationship with happiness. I haven’t
thought about this paper much. Data issues will, I fear, be very difficult to
surmount.
So that covers the first of my main concerns – empirics –
and the content of my second and third paper. My other two fears are the
interdisciplinary nature of my research and that I’m using some things that
aren’t very popular within the disciplines I’m drawing on.
There is a lot of buzz around interdisciplinary research at
the moment, but my impression is that this is mostly about having specialists
in each field come together to work on a complex project. That is quite
different from what I’m capable of, which is having a generalist work on issues
that intersect several areas.
My fears are twofold. First, because I don’t have a hugely
deep training in any of the disciplines I’m working in I will miss some
critical insights or lack some critical technical tools. I might, for example,
not be able to express the psychological aspects of my study using the
appropriate terminology, and my econometric abilities might be deemed too
shallow by economists.
Second, nobody will take the work very seriously because it
won’t fit into an ongoing research stream. For example, the economics stuff in
my paper doesn’t have much to say about reference groups and relative status,
even though this is a huge part of the research agenda on happiness in
economics.
These fears have been amplified during the few conversations
I’ve had with happiness scholars that I’ve met at conferences. They were always
nice but they were also quite dismissive of what I was doing and we had trouble
communicating because I couldn’t articulate myself in a way that fit their
paradigm. For example, economists keep coming back immediately back to
utilitarianism in a way that I think isn’t very healthy for happiness research.
Onto the fact that I’m using stuff on the outer in my
disciplines, there are three main issues here:
First, existential philosophy is generally ignored by
philosophy, except for Heidegger, who isn’t really an existentialist but a
metaphysician. The reason for this is that philosophy has actually never been
interested in the meaning of life, only in metaphysics. Sartre, Beauvoir,
Nietzsche, Kierkegaard and Jaspers did bad metaphysics, so they are largely
ignored in favour of Heidegger, who did great metaphysics.
The happiness literature goes on and on about Bentham and
Aristotle. These guys produced useful words—utilitarianism and eudemonia.
However, Bentham does very little to link utilitarianism to the good life
(quite rightly), and Aristotle provides very little in the way of content to his
notion of Eudemonia. Nietzsche wrote
hundreds of pages of content for Eudemonia, but many Westerners seem to think
him a boorish apologist for German nationalism, so they ignore all that.
On related notes, I’m writing an economics PhD with very
little mathematics and only weak identification at a time when applied micro is
obsessed with perfect measurement and macro is obsessed with dense mathematical
models.
I’m also trying to make psychology take more seriously
issues that dominated its earliest discussions in Freud and Jung but which it
has since tried its darndest to avoid in its quest to be a science because they
are hard to measure.
Getting people to take me seriously when I start bringing in
all this stuff is going to be difficult.
The budget constraint
My model is a utility function:
Utility = agency + SWB + PWB
An obvious question follows: what is the budget constraint?
My initial thoughts regarding an answer were all bad. I now
realise that there are two main constraints: the agency score, and information,
especially about ones authentic preferences and how to satisfy them.
Recall that the agency score is basically derived from
Amartya Sen’s definition of development as freedom. It contains such things as:
Health, Income, Leisure time, Political power, Rights and other legal
protection, ‘Capabilities’, which includes things as simple as access: no good
being a billionaire on a dessert island.
This is more expansive than simply income, which is the
neoclassical budget constraint. This is fitting, because maximising the good
life function involves more than maximising the neoclassical utility function.
Let me give one example to illustrate how this budget
constraint could be interesting. Consider the character Spartacus from the film
of the same name. Spartacus is a slave who fights in the gladiator pits. He
eventually leads a revolt for freedom in which he is very successful because of
its fighting abilities.
Spartacus would not get far maximising an income-constrained
utility function because he doesn’t have any income. Indeed, there is very
little that he has because he is a slave. What he does have is health, defined
expansively to include mad fighting skills and charismatic leadership
qualities. Within this agency constraint he is able to maximise his PWB score
by leading a revolt.
Interestingly, this suggests that the strictness of the
constraint will depend substantially on what preferences the individual has
that are informing their SWB and PWB.
The agency budget constraint also has substantial
implications for the SWB cluster. Someone with a lot of income, health and
power is more likely to be exposed to positive stimuli and less likely to be
exposed to negative stimuli. They will also be able to double down on positive
stimuli and rapidly work their way out of negative stimuli.
For example, someone with good health is less likely to be
in pain and more capable of leaving unpleasant situations like being stranded
in the woods. Someone with money can spend more to prolong the length of their
massage and can escape police extortion by causally paying bribes. As such,
someone with a high agency score is better able than someone with low agency to
maximise an affect function, though uncertainty will be a problem.
Some other thoughts occurred to me once I took this
constrained maximisation perspective. First, many of the stylised facts of the
happiness literature correspond to agency—health, income and political agency
(Swiss referenda literature) notably. Yet we notice that these things seem to
have diminishing returns.
This makes sense if we think about these things as a budget
constraint. If the constraint keeps moving outward but you don’t maximise your
utility function then it’s understandable that pushing the budget constraint
even further out won’t have much effect.
I recognise that I’ve just suggested people have dumb
preferences or at least don’t know how to maximise their utility as derived from
their preferences. This is a huge problem for politics and for a lot of
modelling, but here I think it’s actually quite a reasonable position to take.
The plethora of self-help books, the renaissance of religion in the West and
the popularity of Alan De Botton’s guff suggests to me that people really don’t
know how to make the most of our unprecedented levels of income, health and
political power.
What important ramification that follows from this is that
there is little argument about the agency constraint but a lot of argument
about what preferences and actions make people happy. As such, government
should focus on increasing people’s agency and stay away from increasing their
SWB and PWB. This amounts to government expanding people’s budget constraint rather
than conditioning their utility function.
One thing I really like about thinking of the model in this
way is that it plugs quite nicely into economics in a way that the old model
did not. It’s really just an extension of good old-fashioned rational choice
theory, but bringing psychology into the fold to more realistically define the
utility function in terms of SWB and PWB.
