Disclaimer: This list is heavily influenced by my own research and thus only a tiny subset of important questions in economics and adjacent areas is presented.
I met a young economist at EAGx Berlin who considered switching to AI Safety research because of the apparent lack of impactful research questions in economics. The young economist was under the impression that the case for working on AI Safety is crystal-clear and that there are no important questions in economics. I believe that there are many different problems in economics that can be tractably solved with additional research. You can imagine the conversation as follows:
Young Economist: "AI Safety seems important."
Me: "Sure, but there are tons of great research questions in economics too."
Young Economist: "Like what?"
Me: "Well, there is growth, this is super important you know... and a bunch of other things... really, sooo much I do not even know where to start."
I was unable to provide the young economist with a set of important questions from the top of my head. Therefore, I decided to make this list.
It is not a well-curated research agenda. To have that would require that many share their knowledge.
I have only listed questions that can be addressed by anyone with some quantitative skills and basic economics knowledge. Every research question comes with an angle-of-attack in the footnotes. Most research does not even require genius, but simply labor.
Forecasting
- Can we make use of 'subjective truth serums' to inform policy decisions and make better long-term forecasts?
- Is long-term forecasting distinctly different from short-term forecasting? How to best produce long-term forecasts? What can be robustly said about the latter given the current track record?
- Can Full-Accuracy Scoring improve relevant mid-term and long-term forecasts?
- How to forecast AI Progress and technological change?
- How to communicate forecasts to policy-makers?
- Is there a fundamental estimate of individual predictive skill, such as the Elo rating in chess?
- Awards in (forecasting) competitions are only handed out to a small number of forecasters- are forecasts measurably skewed? How to align incentives?
- Forecasts on events should be biased in favor of an early outcome unless this bias is actively counteracted if forecasters prefer to reap rewards earlier rather than later. This is an important consideration for making robust mid and long-term forecasts. Is this bias observable in practice?
- Assuming a situation in which a forecast affects behavior: Is the forecaster endowed with a decision or power in such a situation? What is the (moral) role of the forecaster in such a situation? For example: Better predictions for economic crisis seem useful, but a potential downside is that predicting a crisis may alter behavior in such a way that it leads directly to a crisis.
- Assuming that future generations further adapt to their economic, socially and cultural environment, they will be very different from us, just as we are extremely different from the society of 1924. Can we forecast such social changes?
- How can we best estimate the outcomes of studies that are not yet carried out?
- How can we best nowcast pandemics?
Futures
I think there might be a lot of value in exploring concrete scenarios. It is important to notice that whilst that particular scenario is extremely unlikely to ever occur, its analysis may discover nonintuitive repercussions and could meaningfully inform our understanding of similar scenarios and is thus useful. The method is simple: Assume a baseline future scenario but make exactly one change to it. Then use our understanding from multiple disciplines to find out what such a future might look like.
A couple of obvious candidates would be
- Catastrophic Climate Change
- Transformative Artificial intelligence
- Supervolcano eruption
- Nuclear winter
- Large drops in fertility/willingness to have kids
- The US or a major western country becoming authoritarian
- Cheap autonomous weaponry
- Very advanced synthetic biology (and engineered pandemics)
- Countries building out solar geoengineering capabilities
- Extremely large economic crisis
One would have to be very specific about the change that is introduced. Such a project would likely take book-form and multiple years of research, so it is ideally suited for interdisciplinary PhDs.
Climate Change
The amount of research regarding climate change is vast and growing. However, given the gravity and complexity of the situation, much seems to be missing yet:
- How do long-term energy forecasts of statisticians, economists and geoscientists compare? Help forecast the adoption of different energy sources.
- How could we improve upon existing climate agreements? Which key assumptions or agents make (future) climate agreements work?
- Can central banks help mitigate climate change? Should central banks do so?
- How do geoengineering methods play into future climate coordinations?
International relations
- How can international agreements improve upon pandemic response?
- How will (military) technological progress, such as the cheap availability of autonomous or biological weapons, change international relations and the future of warfare?
- How successful have attempts to forecast war been?
- Is it possible to get enforcable international agreements?
Macroeconomics & Economic Growth
- Help us understand economic growth and technological progress better. What will future economic growth be and how can we shape it?
- If technological progress is so "fast" right now, why the low growth?
- How should financial markets be regulated? What are the effects of regulation on financial stability?
- What should we expect a non-economic growth world to look like?
- How should we expect TAI to influence economic growth?
- What can be said about an economy with "fast take-off", i.e. where a substantial additional tasks can be performed cheaply by purchasing additional computational power?
- Can central banks help alleviate pressing problems not directly related to economic crisis?
Many issues concerning growth and macroeconomic policy intersect with other areas.
Public Choice and Democracy
- Why are countries currently autocratizing?
- Forecast democratic trends - What does history tell us about our future of democracy?
- How to implement better voting methods?
- How, why and when are existing policies revised? Is there less willingness to get rid of old policies than to create new ones?
- What is the effect of longevity on autocracy?
Development Economics
Important open questions in Development Economics seem to be abundant. Thus, I give some examples rather than concrete research suggestions: A recent study investigated the 'spillover effects' from GiveDirectly donations in Kenya. This study has likely been a big update on the effectiveness of GiveDirectly and has informed our understanding of spillover and multiplier effects as a result of increased spending. The study is, on average, cited twice per week (extremely influential) and could have easily been available five years earlier. Many philantropic organizations (such as GiveWell) seem to draw most of their evidence from studies in Development Economics.
Open Philanthropy has recently published which type of research they think would be very helpful for them.
Another recent study provides evidence on how to discover promising grantees for entrepreneurial microgrants in the developing world. The study suggests that returns to cash givings could be tripled by letting the local community predict entrepreneurial success.
Studies in developing countries inform cost-effectiveness estimates of micro-interventions, such as deworming children or giving cash to the poorest. However, macro-interventions that promote economic growth and organization throughout an entire nation might be far more cost-effective. Unfortunately, it is much more difficult to figure out whether macro-interventions, such as promoting open markets or educational reform actually work well. You cannot run randomized trials with entire countries. Given the importance of such questions, it is likely worthwhile to tackle these questions.
This study also informs grant-making. This and this recent forum post as well as the questions on economic growth might also be interesting.
The post by Open Philanthropy also suggest that they also consider immigration policy to be a important area of future research. Given that the effects of immigration seem to be dependent on a large range of factors (the immigrants, number of immigrants, how they are integrated) studying the contemporary effects of immigration in key countries is highly interesting.
Study (Effective) Altruism and relevant social groups
Studying the EA community and other relevant social groups itself may be very valuable. Furthermore, there are many questions highly related to giving and spending that can potentially be answered by additional research. Some potential research questions are:
- How to increase the funds directed towards effective charities?
- What are causes of peoples engagement with (effective) altruism? Why is effective altruism a recent phenomena?
- How can incentives in academia be changed so as to improve the quality of scientific work (as e.g. has been demonstrated with registered reports)? Which actions can be undertaken that steer academia towards better incentives?
Philanthropic spending across time
- How should a philanthropic actor spend resources across time to maximize utility?
- How should we discount the future?
- Which behavior should we expect to see, if there is mainstream concern that there is a high risk of disaster? What is the interplay between personal discounting and financial market interest rates?
Other
- Should factory farming be taxed? What would the consequences be?
- Can mainstream perception of catastrophic risk lead to broad value-change? What would be the implication of that?
- Theoretical Economists may bring to bear interesting results in AI. After all, economics studies rational agents, and AIs should therefore be even more predictable than humans.
- Can we study large language models to learn about human behavior? Are results from social science experiments with large language models closely representative of experiments with human subjects?
- Can large language models be used to more rigorously analyze text output of human subject in social science experiments, providing the opportunity for unbounded long-form answers as opposed to survey tickboxes?
- Can the different theories of causal inference be reconciled?
- Can Pearls SCM framework be extended to incorporate cyclical causality? If yes, how?
- Review the economics of the catholic church. Why is the institution so robust to change?
Another source of inspiration may be research agendas of others:
