What it's like to intern at Giving What We Can

This summer I spent two months working at Giving What We Can’s Oxford offices as an intern. It was an 

incredibly valuable experience and I encourage anyone with an interest in extreme poverty alleviation to 

. You can find more information about doing a summer internship at Giving What We Can 

 (CEA), the organisations Giving What We Can is part of, shares the office the 

. This means that even though the Giving What We Can team is small, there are constantly 

opportunities to talk to, learn from, and socialise with a much larger group of people who are all trying to improve the world as much as possible

. I doubt I’ve ever met so many great people in a two-month period before.

the best way to learn about effective altruism

. I had read about effective altruism a little bit, mostly from the perspective of global poverty, but being there just doesn’t compare to reading things online (although there is a lot of very high-quality material 

). There was always an interesting conversation going on, and someone I could test my ideas on or ask to explain something. New concerns and old critiques of effective altruism are discussed frequently and openly. Among the interns, there were very varying degrees of commitment to the ideas of effective altruism, but everyone was very serious about genuinely helping their organisation and creating top-quality output.

Giving What We Can takes good care of its interns.

 I first noticed this when I explained that I didn’t have accommodation in Oxford for the summer, and they replied that I could stay in a house which was shared between interns and employees of CEA. But this was certainly not the last example.

. For instance, after one or two weeks working on outreach (encouraging people to start local Giving What We Can chapters), I noticed that this work was probably not a great personal fit for me. I came up with a couple of things that I thought would be a better fit for my skills, one of which was to work on tax deductibility in France for our recommended charities (I’ve lived in Paris for 14 years). The team welcomed these ideas – they operate under the principle that each intern is in the best position to figure out what would be the highest-impact thing for them to do.

Some of the other projects I worked on included translating the effective altruism landing page into French, improving our chapter ‘starter packet’ and writing two research reports on promising interventions. Doing so many different projects really drove home the 80/20 rule: the 80% of the value comes form 20% of what you do. For instance, I spent perhaps 5-8 times more time and energy on my first research project than on my second, but I am not sure the first one was much more valuable. My internship taught me to ruthlessly prioritise, something I became better at but still have room for a lot more progress on.

“Work smarter, not harder” is a cliché of self-help, but CEA is an organisation that has really internalised it. CEA recognises that making its people more productive is a very high-leverage action, and worth investing a lot of resources into. I could always turn to some of my very knowledgeable colleagues for advice on how to work more efficiently, and this idea is baked into the office culture, with things like morning check-ins, monthly feedback sessions, lunchtime talks, and a personal mentor for each employee or intern.

I grew a lot as a person during this internship. It was a 

fun and supportive environment where I felt free to try things and fail

. I was shocked by how often my colleagues offered to take time out of their workday to upskill me – whether about multiple regression, GitHub, how to write a good cold email, or how to plan my day.

For any of these aspects alone, the internship would have been worth my time. 

It’s a great way to help the world while helping yourself develop. If you’re considering applying to be an intern at Giving What We Can or the Centre for Effective Altruism, hesitate no more and go for it!

Out of the box and into this world: behavioural economics and international development

Studies show that people often make bad decisions. Annoyingly bad decisions, for annoyingly petty reasons. Like that time you procrastinated getting back to a friend, for no obvious reason, and it turned out you missed out on a nice dinner, an evening at the pub or some such. In fact, you probably didn’t need studies to inform you that you sometimes make bad decisions. You knew that perfectly well already.

But there is an incredible value to knowing people, in general, are not rational decision-makers. And there is an even higher value to knowing what specific biases influence their decisions and what lapses in judgement people are prone to commit. This value consists in being able to design policy interventions that 

, flagship publication of the World Bank. In this blog article I will outline the thinking behind the WDR and highlight a few promising opportunities for low-cost interventions.

 looks at how small changes in the costs of applying to college affected application rates for students from low-income households. The small changes in costs originated from score reports of standardized tests, such as the ACT, that have to be sent by the test administrator directly to American colleges. In this case, the number of score reports that were sent free of charge increased from 3 to 4. Sending additional reports incurred a small cost of $6. What happened was that the mean number of score reports sent increased from almost exactly 3 to almost exactly 4. The effect was the same across low-income and high-income households.

Why is this strange? Well, it suggests that the students didn’t weigh the costs of sending an additional score report against the potential benefits, they simply went with the default option. Unthinking acceptance of default options seems to be pervasive in human societies, and in some cases it may have huge consequences. The students from low-income households in the example above were foregoing, on average, an additional $10,200 of lifetime earnings by not sending an additional $6 score report.

Automatic acceptance of default options is only one of many cognitive biases that people are subject to. Others include anchoring (an excessive focus on a single piece of evidence, usually the first one presented, when making a decision) and confirmation bias (the tendency to search for, interpret and focus on information in a way as to confirm your preconceived ideas).

These biases, recurring systematically and pervasively, are not in accordance with the underlying assumption of rational, utility-maximizing agents of economic models. 

 do what they would really want to do. They fall in the traps of automatic thinking and pre-defined mental models.

This implies that a heavy usage of economic models with rational agents can lead to a situation in which we ignore 

incredible opportunities to improve people’s lives through interventions that recognize their cognitive biases.

 What’s more, this is particularly relevant for development policy, as 

poor countries lack many of the institutions that make good decisions default options in the West

Figure 1: Good luck maximizing utility, baby.

The World Development Report 2015 draws heavily on the work of behavioural economists Daniel Kahneman and Amos Tversky, and for an overview of their research I would really recommend 

Three principles of human decision-making

In the World Development Report 2015, the World Bank sets up a framework where human decision-making is characterized by three principles.

 Lots of decisions we just make automatically, without much effort or consideration. Accepting the default option is one example of automatic thinking. Hence, 

minor changes to the decision-making environment can have disproportionate effects on outcomes and aggregate well-being.

 Such changes may relate to the timing of the decision or the design of the documents relevant for the decision.

One example comes from Mexico City, where people from low-income households were invited to pick the best $800, one-year loan from a randomized list of loan products representative of the local market. A mere 39% could identify the lowest-cost product from the brochures distributed by the banks themselves. However, 68% could do so with the help of a consumer-friendly leaflet designed by the Consumer Financial Credit Bureau. Making it easier for people to select what they want improves aggregate well-being.

Another example comes from India, where a study by Mani et. Al. (2013)

 showed how financial distress can deplete mental resources needed for important decisions. In the part of India studied, 99% of sugar cane farmers were indebted just before harvest, as opposed to 13% just after the harvest when farmers had received most of their income for the season. The financial distress had a considerable impact on farmers’ mental resources. In a series of cognitive tests, farmers performed consistently worse before harvest relative to after harvest, controlling for other factors such as sleep, work hours, nutrition etc. The mental depletion corresponded, on average, to the lack of a full night’s sleep.

With this in mind, it is perhaps less surprising that another study (Duflo, Kremer & Robinson, 2011)

 found that farmers on average make significantly higher-return investments in fertilizer straight after harvest relative to later in the season. Policy makers should therefore take real care in the timing of important decisions for the poor. Information about better seeds and crops should be distributed 

 harvest, not before, and farmers should be able to decide on theirs children’s schooling 

 Humans are social animals and have innate preferences for cooperation and altruism. We are strongly affected by the social norms in our communities. This is why prevalent corruption can largely be considered a social phenomenon – if you think everyone else will accept a bribe in your position, there is little stopping you from doing so yourself. Opportunities to change social norms exist at large.

An illustrative example of this is included in 

 by Abhijit V. Banerjee and Esther Duflo. Here we are told of school funds in Uganda, and that only 13% of the intended funds ever reached the right schools in the late 90s. After this had been publicized, there was an uproar, and the Ministry of Finance started providing the main national newspapers with statistics on how much money had been sent to local schools. The hypothesis was that the money got stuck in the pockets of local officials. 5 years after, more than 80% of the school funds reached their intended destinations.

 We use a variety of mental models when we think, passed down to us by history and culture. They are not necessarily social norms in the sense that they apply pressure on us to act in a specific way, but they are rather ways of thinking that are easily accessible. Thinking that people are rational is in some sense a mental model, particularly common amongst economists.

An example of how changes to institutions can help change mental models comes from the West Bengal in India. Here, affirmative action led to some regions having women leaders for the first time ever. Only seven years after the leaders had been elected, aspirations for teenage women were much higher. And perhaps more importantly, parents’ aspirations for their teenage daughters were higher and men’s bias in evaluating women in leadership positions was reduced (Beaman et Al, 2012)

Low-cost interventions that change behavior systematically look really promising from a development perspective. Particularly since many of the results in the World Development Report and those mentioned throughout this text have been asserted using robust statistical techniques, primarily randomized control trials. 

Improving decision-making environments and making good choices default options can and should improve well-being in the future. Finding such opportunities should be a clear focus for development professionals.

As a last note, we should always be aware of our own mental models and cognitive biases when thinking about development and policy interventions. And we should make sure that personal liberty is not unjustly compromised in the process of development. 

, by recognizing cognitive biases, shouldn’t be considered an infringement on personal liberty. In the words of John Stuart Mill:

[It] is a proper office of public authority to guard against accidents. If either a public officer or anyone else saw a person attempting to cross a bridge which has been ascertained to be unsafe, and there were no time to warn him of his danger, they might seize him and turn him back, without any real infringement of his liberty; for liberty consists in doing what one desires, and he does not desire to fall into the river. (Mill, 1859)

We look at the evidence regarding the economic benefits of malarial eradication

The Economic Benefits of Malaria Eradication

Estimates of the cost-effectiveness of malarial prevention have tended to focus on the number of deaths which can be averted. 

 currently estimates that it costs $2,838 to avert one death from malaria.

There may however be supplementary reasons to favour these interventions. In particular, improving the health of the population has important knock-on effects on economic productivity. This post gives an overview of the evidence regarding the extent to which fighting malaria can lead to economic growth and the various mechanisms by which this may occur.

Assessing the aggregate economic system-wide effects of health interventions is a difficult process and as a result there remains considerable uncertainty about the overall economic impact of malaria reduction. Nevertheless, we believe that, on balance, 

it seems likely that reducing malaria prevalence may have a substantial positive impact on long term productivity through a mechanism analogous to that of mass deworming.

Developmental, educational and cognitive effects: Getting malaria as a child substantially affects lifetime income

Recently, there has been increased attention on the long term productivity impact of having malaria early in life. This is similar to the case for 

 and potentially hugely important. There are a number of plausible mechanisms by which getting malaria early in life could have a long term impact on future earnings:

Malaria exposure impacts cognitive performance directly

Malaria in pregnant women produces anemia which is associated with worse cognitive development

Disruption to education caused by malaria may have a long term impact on future earnings

Catastrophic health expenditures may limit resources which can be invested in human capital by the family

The long timescales involved and the many confounding factors makes the extent of this impact difficult to evaluate.

One important study by Bleakley (2010) uses a difference-in-differences method to compare the average yearly income of cohorts born shortly before and after malaria eradication campaigns in Latin America and the USA. It found that cohorts born after the anti-malaria campaign in infected areas earned approximately 25% more than the previous generation, after controlling for the differences between cohorts in malaria-free areas. The equivalent number for the USA was 12%.

These are very substantial results (the increases apply to the whole population rather than just those infected with malaria) but have limited external validity because the data examined were from Latin America and the US (where the predominant strain of malaria differs substantially in its effects to the predominant strain of malaria in Sub-Saharan Africa

), and the 1920s in the US and 1950s in Latin America (when the economic ecosystem was very different).

An additional study by Barofsky (2011) in Uganda found that malaria eradication produced 0.3 more years of schooling in the intervention area compared to the rest of Uganda, which corresponds to an annual income gain of between 3% and 11% depending on the conversion rate used

. While these effects are less substantial than the Bleakley paper they are important for two reasons. First, they have greater external validity in Sub Saharan Africa. Second, because the prevalent strain of malaria in Uganda has a higher mortality rate, the results include the countervailing selection effect of removing lower lifetime income people from the population. Barofsky found that the long term impact of malarial prevention on productivity is substantial, even net of this selection effect. 

Barofsky’s paper lends credence to the belief that malaria eradication could have long term productivity effects

 although we would welcome further research in this area.

Costs to individuals and health care system: treating malaria is very expensive, preventing malaria is very cheap

The most direct economic benefit to reduced malaria prevalence is the associated reduction in household health expenditures. Getting malaria is not only deadly but it’s also very expensive. This cost is relatively easy to measure. Household expenditure on malaria treatment in Malawi ranges from about 7% of household income for the average household to 32% of household income for the poorest groups.

 In countries with undeveloped healthcare systems, where out of pocket health expenditures are common, 

malaria can lead to catastrophic health expenditures and financial impoverishment

Where healthcare costs are subsidised, the direct costs of treating malaria fall on the government. The 2015 WHO World Malaria report estimates that, since 2000, 263 million cases of malaria which would have been treated in the public sector have been averted. This is equivalent to a $900m saving for government budgets, of which $610m is attributable to distribution of ITNs/LLINs.

 The 2011 version of the same report noted that “in Rwanda it has been estimated that while it would cost US$ 265 million to sustain the malaria control programme over the next five years, the public health system could avert about US$ 267 million in the costs of diagnosing and treating malaria; and households could avert about US$ 547 million in direct and indirect costs, equivalent to about 7% of household income.”

Figure 1: Estimated number of fever cases seen at public health facilities in Africa in 2015 according to different levels of ITN

for a given number of cases prevented/treated, preventative strategies have an advantage over treatment because they avoid catastrophic health expenditures and reduce the burden on the public health system (see Figure 1).

Labour productivity benefits: are people less productive due to malaria?

The economic cost of malaria is not limited to the direct costs of treatment. Working when you are seriously ill is very unpleasant. As a result, the sick take time off work (or at least are less productive) and those with sick children take time off to care for them.

Time lost per episode varies significantly across settings due to the variability of different types of malaria strains, type of economic activity and access to treatment amongst other factors. The average time lost per adult varies between 1 and 5 days.

 One recent RCT found that a group of farmers who were assigned bednets increased their harvest value by 15%

 have questioned the validity of this result due to baseline imbalances between the treatment and control groups). However, 

there remains considerable debate as to how much malaria impacts short term productivity

. For example, in Malawi, only 52% of adults reported that their illness affected their work.

 Moreover, a larger RCT which looked at 81,597 smallholder contract farmers in 1,507 clusters found no significant impact on cotton production from bednet distribution.

 One possible explanation for this result is that when people are ill they deprioritise less lucrative activities such as basket weaving rather than cotton farming. 

It seems likely that people who have malaria are less productive in the short term but the scale of this impact is highly uncertain.

Evidence on the macroeconomic effects of malarial eradication

Macroeconomic impact of health improvements is particularly difficult to measure. Early attempts used simple country cross-sectional regressions of health on GDP per capita

 but these seem doomed to failure because of omitted variable bias and the causal circularity of health and income (improved health may lead to increased income but increased income also leads to improved health). As a result, much of the literature prefers to extrapolate overall macroeconomic impact from microeconomic productivity gains.

More promising is the use of time-series data and simulations to evaluate the impact of a health shock on income per capita. Ashraf et al. simulated the impact of the immediate eradication of two diseases, malaria and tuberculosis.

 They found that, while the eradication of tuberculosis may lead to immediate increases in income per capita, the eradication of malaria may lead to short term reductions in income per capita. The difference is explained by the different demographic effects of the two diseases. While tuberculosis primarily affects workers in their prime, malaria disproportionately kills children under the age of 5. Malarial eradication therefore increases the dependency ratio of children to workers in the short term, leading to a fall in income per capita. In the long term, declining endogenous fertility rates, combined with the productivity improvements discussed above mean income per capita rises again (see Figure 2).

Figure 2: Simulated impact of elimination of malaria and tuberculosis on income per capita (from Ashraf et al.)

These results have been thoughtfully critiqued by Bleakley.

 While Bleakley agrees that demographic effects mean the impact of malaria eradication is likely to be realised in the long term rather than the short term, he notes, among other things, that the mechanisms through which malaria impacts productivity may not be limited to cases of acute fever (which is assumed by Ashraf et al.) but rather may have more insidious effects on long term productivity. Bleakley concludes that Ashraf’s estimates may be an order of magnitude too low. The debate seems to hinge on the scale of these long term productivity effects, which are discussed above.

Why I not only give what I can but also campaign for Giving What We Can

I love Australian Rules football and cricket, I always have and I still do. But until the age of 22, that was about all I had a passion for.

Then I decided to follow up on a then new passion of mine: climbing mountains. So I chose a small country with big mountains to go to named Kyrgyzstan (also the world’s most difficult country to spell). I was instantly mesmerised by the 7000m mountains that filled my horizons and the beauty of the culture and people. While I was getting my Kyrgyz visa in London, one of the consulate staff said they had a friend who I should visit while there, a professor at a university in the east of the country. I was a newly graduated teacher myself so I thought this would be a good idea to go and visit and maybe volunteer for a week before I took off to the mountains.

That week has more or less lasted for the past 15 years and now in over 80 countries.

I completely fell in love with volunteering, cultural immersion and working with people to address issues of equality and justice. In my first month of volunteering in beautiful Karakol, in eastern Kyrgyzstan, I worked with an incredible group of women my own age and learnt more from them that I had learnt from anyone else in my life to that point. While I got a degree from a university in Australia, it was really the university in Kyrgyzstan that gave me an education in life.

A few months after my volunteering in Kyrgyzstan and then Mongolia I did some paid teaching in South Korea. There was a moment in South Korea that it hit me:. Why…? Why me…? Why was the world so unequal? That moment was when the paper money of Korean Won hit my hand after my first week of teaching. 

I had just been paid more money per hour than my friends and colleagues in Kyrgyzstan earned in a month, but here’s the thing - I didn’t worker harder than my friends, I wasn’t smarter, I didn’t work longer hours. The only difference between us was where we were born. Having been born in Australia, I had access and opportunity to do what I wanted in the world.

When I felt the world shift as the cold facts of reality and injustice dawned on me, it struck me that I had to do more to find out answers and work on solutions. My journey since Kyrgyzstan 15 years ago has taken me into two definite strands of life:

Listening, learning and trying to be of service to communities in developing countries

Advocating, campaigning, awareness-raising and educating others in developed countries.

What Giving What We Can has added to my life is not only a framework to have my financial justice house in order by giving at least 10% of any money I earn (since I don’t earn a salary from any one organisation and mostly still volunteer). 

It has also given me an opportunity to advocate on why overseas aid is important, how effective it is, and why I care and contribute not only in donations but also in time, effort, energy and passion towards making sure we all have access and opportunity no matter where we are born.

In September this year I visited Kyrgyzstan once again for the first time in 15 years. I no longer saw the same level of extreme poverty. It seemed people no longer had to make terrible choices between less food per day or to buy the medicines they needed. That is the basic kind of choice and opportunity I hope to see for everyone, everywhere and forever.

Giving What We Can is not only about getting our finances in order. It is also about engaging us with great people doing great things. So be sure to not just give your money but also lend your voice as to why giving is important to you. I strongly encourage everyone to share with others - especially your local MP - why you care about making a difference in the world and be a part of the solution for a better world for everyone, everywhere and forever.

Your voice is just as important as your donation. It is up to us to create a community and culture of being generous to others, so that our community, business and political leaders can also follow our lead or make good decisions on our behalf. We are lucky to be able to be part of the movement that can end extreme poverty, reduce inequality and protect the planet. Make sure others know about it and the positive impact Giving What We Can is having on the global community, contributing to opportunity for all.
