Question A: Establishing a sovereign wealth fund to invest in domestic infrastructure, emerging technologies, and/or strategic sectors would bring substantial benefits to the US economy over a ten-year horizon.
Vote | Confidence | Median Survey Vote | Median Survey Confidence |
---|---|---|---|
Comment: Creating positive incentives in those areas would bring substantial benefits. For example via broad subsidies and taxes at sector level. Much less clear implementing this via sovereign wealth fund that buys equities in specific companies is the right policy implementation.
|
Question B: For the US, establishing a sovereign wealth fund would be substantially better for citizens relative to reducing public debt burdens.
Vote | Confidence | Median Survey Vote | Median Survey Confidence |
---|---|---|---|
Comment: At lower debt levels (say before the GFC) I would have argued for the US to issue safe debt and buy riskier assets. At present high level of debt, adding more government leverage and risk taking is a far less obvious policy.

Question A: A bitcoin's value derives from the belief that others will want to use it, which implies that its purchasing power is likely to fluctuate over time to a degree that will limit its usefulness.

Question A:Stock markets around the world have seen an increasing concentration of trades in or near the closing auction. In the US, for example, about a third of all S&P 500 stock trades are now executed in the final ten minutes of the session, up from 27% in 2021.
The increased concentration of trading in the final minutes of the trading day has a measurably detrimental effect on market quality.

Question A: Public companies that pursue social and environmental initiatives bear no measurable costs (in terms of lower profits) relative to similar companies that do not pursue such initiatives.
Vote | Confidence | Median Survey Vote | Median Survey Confidence |
---|---|---|---|
Comment: There are good or bad projects. If they pursue bad (low or negative NPV) projects purely to achieve a label on ESG the costs would be measurable. If they pursue good projects, which might include many with ESG orientation, then they would stand to gain.
|
Question B: Public companies that pursue social and environmental initiatives benefit from a measurably lower cost of capital than similar companies that do not pursue such initiatives.
Vote | Confidence | Median Survey Vote | Median Survey Confidence |
---|---|---|---|
Comment: I have not seen super reliable evidence on this. Estimating the cost of capital is notoriously difficult. Also the "benefits" might have been transitory from a moment when investors paid more attention to ESG labels.
|
Question C: There are substantial social benefits when managers of public companies make choices that account for the impact of their decisions on customers, employees, and community members beyond the effects on shareholders.
Vote | Confidence | Median Survey Vote | Median Survey Confidence |
---|---|---|---|
Comment: There are many externalities (pecuniary, demand, environmental, national security). It is often the role of the government to make managers (and other actors) internalize the externalities (regulation, tariffs, etc...)

Question A: It seems likely that Japanese authorities intervened in the foreign exchange market recently to prop up the yen – see, for example: https://www.ft.com/content/455784ec-0465-46ee-8c73-fc5ce3e31c37. In such circumstances, intervention refers to purchases or sales of domestic or foreign currency without changing the monetary policy stance.
Large-scale intervention by public authorities in currency markets can move exchange rates substantially.
Vote | Confidence | Median Survey Vote | Median Survey Confidence |
---|---|---|---|
Comment: Intervention has an impact via financial frictions on exchange rate markets. The more constrained the risk bearing capacity of the private market, the more intervention (for given size) moves the exchange rate

Question B: The effectiveness of foreign exchange interventions can last beyond one month.
Vote | Confidence | Median Survey Vote | Median Survey Confidence |
---|---|---|---|
Comment: Clean empirical evidence is hard to find. Intervention is endogenous and so far we do not have papers credibly identifying the effects. My judgement comes from combining theory and existing evidence, so uncertainty is high, but on balance more positive than negative on effects.

Regulator Probes BlackRock and Vanguard Over Huge Stakes in U.S. Banks – The WSJ reports that ‘The FDIC is scrutinizing whether the index-fund giants are sticking to passive roles when it comes to their investments in U.S. banks.’

Question A: Allowing short selling of financial securities, such as stocks and government bonds, leads to prices that, on average, are closer to their fundamental values.
Vote | Confidence | Median Survey Vote | Median Survey Confidence |
---|---|---|---|
Comment: While it is possible that enhanced speculative activity might cause distortions (especially in the short run and during a crisis), overall the first order effect is to get closer to fundamentals on average
|
Question B: When short sellers start to establish substantial short positions in a stock, the stock is likely to have been overvalued.
Vote | Confidence | Median Survey Vote | Median Survey Confidence |
---|---|---|---|
Comment: This variation, especially at high frequency might be more about speculation. So much would depend on the frequency
|
Question C: Requiring investors to disclose short positions in a stock at the equivalent threshold as they are required to do for long positions would improve the informativeness of stock prices.
Vote | Confidence | Median Survey Vote | Median Survey Confidence |

Application of the principles of modern portfolio theory allows investors in practice to achieve substantial improvements in the risk-expected return trade-off relative to naive strategies such as equal-weighting that do not take account of return covariances.

Question A: The Federal Reserve has begun quantitative tightening (QT) to reduce the size of its balance sheet. Fed holdings of Treasury securities have declined by $800 billion relative to the March 2020 peak. The Fed currently holds $4.9 trillion of Treasury securities, significantly larger than the $2.5 trillion holdings prior to the Covid pandemic.
A reduction in Fed holdings of Treasury securities measurably increases the interest rate on long-term U.S. Treasury bonds.

Question B: A reduction in Fed holdings of Treasury securities measurably increases volatility in the Treasury market.

Question A: September 2023 was the 25th anniversary of the collapse of Long-Term Capital Management (LTCM). In response to LTCM's troubles, the Federal Reserve orchestrated a multi-billion dollar rescue package by a consortium of banks and it cut the Federal funds rate target by 75 basis points within six weeks.
The hedge fund sector's contribution to systemic risk is substantially lower today than at the time of LTCM.
Vote | Confidence | Median Survey Vote | Median Survey Confidence |
---|---|---|---|
Comment: The hedge fund sector has expanded and is still largely unregulated. Much of it has moved offshore, Cayman Islands, or in onshore/offshore financial centers like Luxembourg and Ireland. Its levered positions recently contributed to US treasuries volatility and the UK LDI crisis.

Question B: Financial market participants' expectation that the Fed will aggressively ease monetary policy in response to financial market dislocations is a substantial source of financial instability.
Vote | Confidence | Median Survey Vote | Median Survey Confidence |

Question A: New Money Market Fund (MMF) Rules: The SEC adopted amendments to the MMF rules, including a new mandatory liquidity fee for institutional prime and tax-exempt funds. The liquidity fee would trigger when daily net redemptions exceed five percent and when the costs associated with such redemptions are more than de minimus. https://www.sec.gov/news/press-release/2023-129
The new liquidity fee will substantially reduce the likelihood of runs on MMFs.

Question B: Regulation that prevents state pension funds from considering environmental, social, and governance factors in investment decisions even if these factors are material for risk and expected return would make retirees measurably worse off.

Question A: By issuing inflation-indexed bonds, and thereby providing a long-term real safe asset for pension funds and retirement savers, governments can make a substantial contribution to social welfare.
Vote | Confidence | Median Survey Vote | Median Survey Confidence |
---|---|---|---|
Comment: In practice these bonds have tended to be illiquid and attract mixed interest. There are a number of measurement and indexing issues. The practical impact has been somewhat disappointing even if there are good theoretical reasons for this market to exist.
|
Question B: Issuance of inflation-indexed bonds substantially helps government commit to a responsible fiscal and monetary policy.
Vote | Confidence | Median Survey Vote | Median Survey Confidence |

Comment: Governments have many levers to tamper with the real payoff of debt (default, taxes, financial repression). Inflation is one of these levers. Inflation-indexed bonds reduce the ability to use this lever, but at the risk of the government simply using another lever more.

Question A: The collapse of a major crypto intermediary will have little impact on the wider economy and the stability of the traditional financial system.
Vote | Confidence | Median Survey Vote | Median Survey Confidence |
---|---|---|---|
Comment: At the current scale and level of usage, crypto does not seem systematic enough to cause major issues to the wider financial system. But my level of uncertainty is high since I am not an expert on the issue and have not seen a detailed data analysis.
|
Question B: The collapse of a major crypto intermediary suggests the need for the crypto asset class to be more tightly regulated.
