The Unassuming Economist

From a paper by Sunil Sharma:

“Despite over a decade of reforms, financial systems remain fragile, and with the ongoing degradation of the biosphere addressing these fragilities is becoming even more challenging. The green digital transition requires innovation and experimentation. Laws and rules must support competition for novel technologies and solutions, allow for failure, and facilitate re-allocation of labor, real assets, and capital. Hence, the case for robust banks, nonbank financial intermediaries, and market infrastructure is even more urgent and compelling.

Complexity and deep uncertainty characterize the green digital transition and the operation of economic systems. Taking this seriously means recognizing that simpler heuristic approaches may dominate complicated optimization strategies. We must be cognizant of what we know, what we can know over relevant time horizons, and what may be unknowable.

Given the weaknesses of the current approach to financial regulation and oversight, changes in institutional and financial structure should be considered that would reduce the use of “runnable” short-term debt, create more transparency and better incentives for all players, and hence lessen the need for complicated rules, explicit and implicit State guarantees, and interventions in markets.

In an era of chronic and acute disruptions, durable price and financial stability will require not just accounting for financial hazards, but also engaging in promoting a structural transition. With time running out and the world approaching critical ecological thresholds, central banks and financial regulators will have to integrate environmental considerations into their operations and policies and collaborate more closely with other government agencies.

To increase the systemic resilience of the financial sector, the policy essay argues for:

(i) simplicity in prudential rules; (ii) higher buffers in financial institutions; (iii) greater modularity in the structure of the financial system; (iv) better use of market forces and public discipline; and (v) more credible and effective supervision.”
